Reviewed rectangle on a pergola
You already have four solid anchors and a span longer than the cloth, and you want the fixing kit in the same box. Check the curve: the centre can stay saggy, and rain can sit in the belly.
Sun sail comparison 2026
The best sun sails, compared.
Top pick: Mokani 3 x 4 m rectangle – Highest stored score at 80: 4.3 from 672 reviews, with turnbuckles, plugs and a bag in the box. Best value: HEYOMART 2 x 2 m square – Best value at about £19.99: 4.0 from 1,575 reviews, a sample of its own, below the top score. Updated 16.10.2026.
A sun sail is fabric with a corner ring, tensioned between walls, posts or a pergola. Most are polyester or, and two are 120 g/m² polyethylene. You choose by the anchors you already have, by rain versus airflow, and by the shaded patch after the sides curve. A flat coated sail holds water, and these listings warn about heavy rain. BS EN 13561 does not cover wind resistance of non-retractable products. A seller’s 95 or 98 percent UV line is not an NHS certificate. From March to October, use shade between 11am and 3pm. Anchors, fabric, size and slope are in the [sun sail buying guide](/hub/sun-shades/sun-sail/sub/sun-sail-buying-guide). It is not a freestanding parasol and it is not a retractable awning.

Which sun sail fits this patio?
Question 1 of 2
How many solid anchors do you have?
The best sun sails in detail
Our view
The Mokani 3 x 4 m grey sail is the only listing here that ships turnbuckles, pad eyes, plugs, six ropes and a bag, at £41.99. It holds 4.3 from 672 amazon.co.uk reviews, the highest star line in this set among sails with hundreds of reviews, which is why it is the top pick on the stored scores. In the first 50 UK blocks, people praise the stitching, the mid-side fixing points, and shade over a hot room, a dog kennel or a fish pond, and at least one sail stayed up into a third season. The centre still sags when the edges are tight, and one person cut a hole because rain sat in the belly. Several buyers found it too large once they added the 1.5–2 ft gap, and they take it down when the wind picks up. Continuous heavy rain can seep even though the attribute says waterproof.
Pros
- 4.3 from 672 reviews, the highest stars with a large sample
- Turnbuckles, pad eyes, plugs, ropes and a bag in the box
- Mid-side fixing points as well as the corners
- At least one review covers more than one UK season
Cons
- Centre stays saggy and rain can sit in the belly
- £41.99 is the highest price in this set
- Too large once the fixing allowance is added
- Taken down when the wind picks up
Best for: A span clearly longer than 3 x 4 m, where you want the fixing kit in the same box.
Less suitable: A tight gap, a gale, or a cover that must stay dry in continuous heavy rain.

Common questions
What fixing hardware is in the box?
Two turnbuckles, two carabiners, four pad eyes, 16 screws and plugs, six ropes and a carry bag, plus the sail.
Can it stay up in heavy rain?
The bullets say it resists moderate water pressure and that continuous heavy rain may cause slight seepage. One stored review describes a sagging belly that held rain.
How much gap should I leave?
The listing says leave 1.5–2 ft between the fixing point and the sail, and tilt it 20–40 degrees.
Our view
The Mokani 3 x 3 m grey sail is a 160 g/m² polyester rectangle at £30.99, sold with six ropes and no wall plugs. Across 2,002 amazon.co.uk reviews it sits at 4.2, and the first 50 UK blocks often call it easy to hang, easy to move, and enough for a light shower. One reviewer who already owned a beige triangle says the grey cloth blocked more sun, and others prefer the seams and metal loops to cheaper sails. The bullets say waterproof while the attribute says water resistant, and continuous heavy rain can seep even on the suggested 20–40 degree slope. Corner stitching is called weak in one review, and another wants extra holes along the 3 m side so the edge does not flap. The listing itself says the curved sides will not hang like the photo, so you still buy the anchors and accept a smaller shaded belly.
Pros
- 4.2 from 2,002 reviews, the largest sample here
- Six ropes included; easy to take down and move
- Reviewers describe light showers as manageable
- Grey cloth preferred to an old beige triangle in one review
Cons
- Plugs and turnbuckles are not in this box
- Waterproof bullets clash with a water-resistant attribute
- Corner stitching called weak in one review
- Curved sides will not match the photo
Best for: A patio or pergola where you already have solid anchors and want a widely reviewed 3 x 3 m rectangle for sun and light rain.
Less suitable: A custom pergola blind, a winter roof, or a wall you still need to plug.

Common questions
Does this 3 x 3 m sail include wall plugs?
The box list is one canopy and six ropes. Turnbuckles and plugs are not on this ASIN. They are listed on the Mokani 3 x 4 m sail.
Is it waterproof?
The bullets say waterproof and also say continuous heavy rain may seep. The attribute says water resistant. The listing suggests a 20–40 degree slope.
Will it hang like the photo?
The listing says curved sides change the shape slightly, with a 1–2 cm difference between rings, and that gravity stops it matching the main picture.
Our view
The KAHEIGN cream sail is a 2.5 x 3 m, 120 g/m² polyethylene cloth at £18.99, with four 1 m ropes and no hooks. The page shows 4.2 from 1,005 reviews, and the first 50 UK blocks are the same text as the grey KAHEIGN, so that count is one sample. Reviewers like the light cloth for sun, and say the colour held into a second season when it was pitched as pictured. A review in the file says it is certainly not waterproof, which fights the waterproof attribute on this colour. The middle is about 200 mm under the stated size, and tie ribbons started to fray after one week. Water sits in the middle if you hang it flat, and those short ropes will not bridge a wide gap to the wall.
Pros
- £18.99 for a 2.5 x 3 m polyethylene sail
- Reviewers report sun block and a colour that held a second season
- Light cloth that is easy to fit, in the shared sample
- A large 4.2 line if you count the two colours once
Cons
- The review text is the same as the grey ASIN
- A review says it is certainly not waterproof
- Ties frayed within a week
- Four ropes are only 1 m long and hooks are not included
Best for: Summer shade where rain may pass through and you already have hooks within a short rope’s reach.
Less suitable: A rain roof, or a second highly reviewed sail if you have already counted the grey listing.

Common questions
Is this the same product as the grey KAHEIGN listing?
The cloth claim, size and the first 50 UK review blocks match the grey ASIN B0FDWXLZN2. The price, colour and listed weight differ. Count the reviews once.
Will it keep rain off?
The attribute says waterproof. A review in the file says it is certainly not waterproof. The bullets also describe air permeability.
How long are the ropes?
Four ropes, 1 m each. Hooks are not listed in the box.
Our view
The grey KAHEIGN repeats the same 2.5 x 3 m, 120 g/m² polyethylene claim as the cream sail, at £24.99. The stored review blocks open with the same sentences, and both pages print 4.2 from 1,005, so this is not a second opinion. Praise in that shared text is sun block, an easy fit and a colour that held when the sail was sloped. The criticism is the same: not waterproof, a middle about 200 mm narrower, and ribbons that fray within a week. This listing’s attribute says water resistant, while the cream attribute says waterproof, and the item weight here is 850 g against 120 g on the cream page. You pay about £6 more for a colour and a weight figure the file does not reconcile.
Pros
- The same sun-shade comments as the cream listing, counted once
- The water-resistant attribute sits closer to the not-waterproof review
- A four-corner 2.5 x 3 m shape
- Grey if you want a darker cloth than cream
Cons
- £24.99 for a duplicated review set
- Listed weight of 850 g clashes with 120 g on the cream ASIN
- Not a rain cover in the shared review
- Ropes are 1 m and hooks are not in the box
Best for: Only if you specifically want grey and you treat the cream reviews as the one sample.
Less suitable: Anyone adding 1,005 to the cream count, or anyone who needs the cloth to keep rain off.

Common questions
Why is the review count the same as the cream sail?
The raw file repeats the same UK review blocks and the same 4.2 from 1,005. It is not a second sample.
Which weight is listed?
This ASIN says 850 g. The cream ASIN says 120 g. Both say 120 g/m² and 2.5 x 3 m.
What does the listing say about water?
The attribute says water resistant. The cream listing’s attribute says waterproof. A shared review says it is not waterproof.
Our view
The HEYOMART cream square is a 2 x 2 m, 160 gsm polyester sail at £19.99, with four pad eyes and four 200 cm ropes. It sits at 4.0 from 1,575 amazon.co.uk reviews, a large independent sample at the low end of this set, which is why it is the best value here even though the stars sit below the Mokani pair. Reviewers use it over children or a pond, and some compare the price with a large parasol, once they accept the size. One UK review measured 1.42 m across the middle of a 2 m side, so part of the patio stays in the sun. Sag within two months, anchor seams failing in under four months, and rotting tie cords all appear in the first 50 blocks. The title says waterproof, while the bullets state a 400 mm water head and say water resistant, not waterproof.
Pros
- £19.99 with 4.0 from 1,575 independent reviews
- Four pad eyes and four 2 m ropes
- Reviewers call it easy to put up and take down
- A usable patch for a gazebo or pond if you accept the curve
Cons
- Middle measured at 1.42 m on a 2 m side
- Anchor seams failed in under four months in one review
- Cords rot and the cloth can stretch so it will not re-tension
- The title says waterproof and the bullets say it is not
Best for: A small patio, gazebo or pond where £20 and a real review sample matter more than a taut long-term roof.
Less suitable: A 3 m span, a rain cover, or a cloth you need to stay tight for several years.

Common questions
Is the 2 m size the shaded width?
The listing says the size is the distance between the corner tips, not the width of the shaded cloth. One UK review measured 1.42 m across the middle of a 2 m side.
Is it waterproof?
The title says waterproof. The bullets state a 400 mm head and say water resistant, not waterproof. The attribute says water resistant.
Are wall anchors included?
Four pad eyes and four 200 cm ropes are listed. Reviews say you still buy decent anchors separately.
Our view
The Ghligna grey rectangle is sold as a 3 x 3 m 420D Oxford sail at 180 gsm, with 316 stainless D-rings and four 2 m ropes, at £24.99. amazon.co.uk shows 4.0 from a single review, and that text only says it does the job and is value for money. There is no stored complaint to quote, and one content sentence is not a durability record. The title size is 3 x 3 m while the item dimensions attribute says 30 x 30 mm, which cannot both describe the sail. Hooks are not in the box, and the listing asks you to leave 30–45 cm between the fixing points and the D-rings. The water line is limited to light showers, so you can read the cloth specification and you cannot yet read a wet British week.
Pros
- 420D Oxford at 180 gsm, a heavier paper spec than the 160 g/m² sails
- Four 2 m ropes and 316 D-rings
- The single review does not describe a fault
- £24.99 for a stated 3 x 3 m rectangle
Cons
- 4.0 from one review only
- The dimensions attribute says 30 x 30 mm
- Hooks are not included
- The water claim is light showers only
Best for: A spec-sheet 3 x 3 m sail only if you accept almost no UK feedback.
Less suitable: A decision that needs a review sample, or a listing whose size fields must agree.

Common questions
How many reviews are stored?
The listing line is 4.0 from 1. The only UK text says it does the job and is value for money. It does not describe a fault.
What size should I trust?
The title and size are 3 x 3 m. The item dimensions attribute says 30 x 30 mm. Those cannot both be the sail.
What gap does the listing ask for?
Leave 30–45 cm between the fixing points and the D-rings. Hooks are not in the box list.

The RICHIE wine red rectangle is a 2 x 3 m 300D Oxford sail at £25.45, with ropes in the box and hooks sold separately. The star line is 3.9 from 298 reviews, and the first 50 UK blocks also describe other sizes, so treat them as comments on the listing family. Where a 2 x 3 m sail is mentioned, one buyer puts the shaded patch at about 1.4 m by 2.4 m because the sides curve. People mention an easy fit and a cooler spot, including beside a caravan, and some say the construction held for weeks under tension. Sag in the middle pools rain, and buyers wished they had ordered the next size up after the cloth stretched in hot then wet weather. The listing says leave 1.5–2 ft for hardware you still have to buy.
Pros
- 2 x 3 m 300D Oxford at £25.45 with ropes included
- Family reviews mention an easy fit and a cooler spot
- One 2 x 3 m note gives a shaded patch of about 1.4 m by 2.4 m
- Construction described as holding for weeks under tension
Cons
- 3.9 from 298, and the blocks mix other sizes
- Rain pools when the centre will not go taut
- Hooks are a separate purchase
- Buyers in the sample wanted the next size up
Best for: A small pergola or caravan side where a 2 x 3 m corner-to-corner cloth is enough and you will buy the hooks.
Less suitable: Anyone who needs the reviews to be only this colour and size, or a span that cannot spare 1.5–2 ft.

Common questions
Are the wall hooks included?
Ropes are included. The listing says hardware and hooks are purchased separately, and to leave 1.5–2 ft for that hardware.
Do the reviews match this wine red 2 x 3 m sail?
The star line is 3.9 from 298. The first 50 UK blocks also describe other sizes and colours, so treat them as family comments.
Why might the shade be smaller than 2 x 3 m?
The sides are curved. One review of a 2 x 3 m sail puts the shaded patch at about 1.4 m x 2.4 m.
Our view
The ABTZENO light grey sail is the cheapest here at £12.99, and the title calls it a 3.2 x 3.2 x 4.5 m triangle. The size attribute says 3 x 4 m and the item dimensions say 40 x 30 cm, so the file does not tell you what will arrive. The star line is 3.7 from 7 reviews, with six UK texts stored. Praise is short: up all summer with no rips, and called very strong. Criticism in the same small set says the corner stitching is not very strong, that it hung like a hammock, and that it was smaller than the dimensions showed. Ropes and D-rings are listed, a screw kit is not, and the UV line jumps from 95 percent in the title to up to 98 percent in the bullets.
Pros
- Lowest price in the set, at £12.99
- A few short reviews say it stayed up all summer without rips
- Ropes and D-rings are listed
- A triangle title if you only have three anchors
Cons
- Three size fields disagree
- 3.7 from 7 reviews, with six texts stored
- Hammock sag and weak corner stitching in the sample
- One review says it was smaller than the dimensions
Best for: A trial shade only if you can return it when the cloth does not match the title.
Less suitable: Any patio where the shaded width has to be known before you drill.

Common questions
What size is this sail?
The title says a 3.2 x 3.2 x 4.5 m triangle. The size attribute says 3 m x 4 m. The item dimensions say 40 x 30 cm. The file does not resolve that.
Does the box include screws?
The bullets include free ropes and D-rings. A screw and pad-eye list is not in the bullets. The page asks whether hardware is included.
What do the six stored reviews say?
Praise is strength and a summer with no rips. Criticism is weak corner stitching, a hammock sag, and a sail smaller than the dimensions shown.

The YOUNTHYE grey square is a 3 x 3 m 420D Oxford sail at £28.99, listed at 1.34 kg, with four 2 m ropes, two tighteners, two carabiners, four pad eyes and 16 expansion screws. The raw amazon.co.uk file has no Customer Reviews line and no review text, so there is no star rating to lean on. The stated size and the item dimensions both say 3 x 3 m, which is more consistent than several neighbours in this set. The bullets claim 95 percent UV block and a waterproof cloth, and they do not give a wind speed when the page asks about strong winds. Included plugs are not a design for every wall, because a fascia or tired mortar can still fail under tension. You are buying a kit and a cloth specification, not evidence from UK buyers in this file.
Pros
- 3 x 3 m square with matching dimension fields
- A fixing kit with tighteners, carabiners, pad eyes and screws
- Listed weight of 1.34 kg is a plausible mass for this cloth
- 420D Oxford with a PU coating on the specification
Cons
- No stored amazon.co.uk reviews
- No wind figure on the listing
- The included plugs do not suit every wall
- The waterproof line has no buyer check in this file
Best for: A 3 x 3 m kit only if you are willing to judge the cloth yourself on arrival.
Less suitable: A choice you want backed by reviews, or a wall you have not checked for the pull.

Four 2 m ropes, two awning tighteners, two carabiners, four pad eyes and 16 expansion tubes and screws.

The page asks if it withstands strong winds. The bullets do not give a wind speed or a standard.

The DAJAVE grey rectangle is a stated 3 x 4 m 420D Oxford sail at £32.99, listed at 1.62 kg, with four 2 m ropes, carabiners, lag screws, pad eyes and expansion screws. There is no Customer Reviews line and no review text, so the 420D label is unread by buyers in this file. The item dimensions attribute says 10 x 10 mm, which fights both the 3 x 4 m size and the 1.62 kg weight. The bullets limit it to light and moderate rain, say continuous heavy rain may leak slightly, and suggest a 20–40 degree angle. That water line is more cautious than a bare waterproof title, and it is still unchecked by a stored review. At £32.99 you are close to the Mokani 3 x 3 m, which has 2,002 reviews, and this listing has none.
Pros
- A stated 3 x 4 m sail with screws and pad eyes in the box
- Weight listed at 1.62 kg
- The rain line is explicit: light to moderate only
- A 20–40 degree slope is stated on the listing
Cons
- No stored reviews
- The dimensions attribute says 10 x 10 mm
- £32.99 without a UK review sample
- The seller excludes heavy rain
Best for: A 3 x 4 m kit only if you accept an unreviewed listing and set aside the millimetre field.
Less suitable: Heavy rain, or a shopper who can use a reviewed sail of a similar size instead.

Common questions
Will it take heavy rain?
The bullets say light to moderate rain only. Continuous heavy rain may leak slightly. They suggest a 20–40 degree angle.
Why do the dimensions say 10 mm?
The item dimensions attribute is 10 x 10 mm. The size is 3 x 4 m and the weight is 1.62 kg. The millimetre figure is a conflict, not a sail size.
Are there reviews?
No Customer Reviews line and no review text.

The YOUNTHYE grey triangle is listed as a 3 x 3 x 3 m 420D sail at £23.99, with four 2 m ropes, two tighteners, four pad eyes and 16 screws. A triangle has three corners, so that four-point kit does not match the shape. The item weight in the file is 10 g, which cannot be a 3 m Oxford sail, while the square from the same brand lists 1.34 kg. There is no Customer Reviews line and no review text. The dimension attribute says 3 x 3 m while the title says three equal 3 m sides. The bullets claim a waterproof cloth and 95 percent UV block, and they do not answer the wind question with a speed or a standard.
Pros
- An equilateral 3 m title if you have three anchors
- A fixing kit is listed in the box
- £23.99, below the reviewed Mokani rectangles
- 420D Oxford on the material line
Cons
- No stored reviews
- The item weight of 10 g conflicts with a 3 m sail
- Four ropes and four pad eyes for three corners
- The dimension attribute says 3 x 3 m rather than 3 x 3 x 3 m
Best for: Only if you need a triangle-shaped kit and you can check the cloth on arrival against a sensible weight.
Less suitable: Anyone treating 10 g as a real mass, or a wall you have not assessed.

Are there reviews?
No Customer Reviews line and no review text in the raw file.
Does the kit match three corners?
The kit lists four ropes, four pad eyes and two tighteners. The sail is a triangle.

The DAJAVE grey triangle is listed as 3 x 3 x 3 m of 420D Oxford at £19.99 and 1.33 kg. The box lists three 2 m ropes, which matches three corners, and four pad eyes, which does not. There is no review line and no review text. The dimensions attribute says 10 x 10 mm, the same clash as on the DAJAVE rectangle. Rain is limited to light and moderate, with a warning against heavy rain and a 20–40 degree suggestion. The 1.33 kg figure is at least a believable mass, unlike the 10 g printed on the other triangle in this set. You still do not get a buyer account of sag, stitching or the real shaded patch.
Pros
- £19.99 for a stated 3 m triangle
- Three ropes match three corners
- Weight listed at 1.33 kg
- The seller limits it to light and moderate rain
Cons
- No stored reviews
- Four pad eyes for three corners
- The dimensions attribute says 10 x 10 mm
- Heavy rain is excluded by the listing itself
Best for: A low-cost triangle only if you can return a cloth that does not match 3 m sides.
Less suitable: A structural shade, heavy rain, or a decision you want based on star ratings.

Common questions
Does the kit match a triangle?
The box lists three ropes and four pad eyes, plus two carabiners and two lag screws. A triangle has three corners.
What rain does the listing allow?
Light to moderate rain. It says not to use it in heavy rain, and that continuous heavy rain may leak slightly.
Are there reviews?
No Customer Reviews line and no review text.
How we compared
Scores compare the twelve amazon.co.uk listings kept in this set. Prices, stars and review counts are the stored listing figures from 16 October 2026. There is no laboratory test, and no sail was tensioned or soaked. The scores do not name a sun sail for every patio in Britain. Each score is out of 100 in four blocks, and the weights below sum to 100.

Sun sail buying guide
Choose the anchors and the cloth before the title size. Four solid points suit a rectangle or square. Three suit a triangle, which shades less once the sides curve. Coated polyester or Oxford is the waterproof claim, with a heavy-rain caveat. Polyethylene is the breathable cloth in this set. If you are deciding between a sail and a parasol, start with [parasol or shade sail](/hub/sun-shades/blog/parasol-or-shade-sail).
What is a sun sail?
A sun sail is a shade sail: fabric with a corner ring, tensioned between walls, posts or a pergola. It is not a freestanding parasol and it is not a retractable awning. The twelve amazon.co.uk listings here run from about £12.99 to about £41.99. Most are PU-coated polyester or Oxford. Two are 120 g/m² polyethylene. You choose by the anchors, by rain versus airflow, and by the shaded patch after the sides curve. The corner-to-corner title is not the shadow.
Best for
- A patio or pergola where the anchors are already solid
- Summer shade where you accept that rain may pass or seep
Not ideal for
- A winter roof, a gale, or continuous heavy rain
- A wall you have not checked, or new posts on a listed building
Mistakes to avoid
- 1
Treating the title as the shadow
Corner-to-corner sizes shrink once the sides curve. A stored note puts a 2 m by 3 m sail at about 1.4 m by 2.4 m of shade, and a 2 m side has been measured at 1.42 m across the middle.
- 2
Reading waterproof as a winter roof
Coated cloth still carries a heavy-rain caveat, and a flat sail holds water. Do not stand under a belly that is filling, and take the sail down before a gale.
- 3
Ignoring a 10 g or 10 mm field
A 10 g weight is not a 3 m sail, and 10 x 10 mm or 30 x 30 mm is not the cloth. Counting both KAHEIGN review totals, or plugging a fascia because screws were in the box, repeats the same sort of miss.
What to weigh up
Anchors, size and slope
HighStart with the points you can fix to. Four solid points suit a rectangle or square. Three suit a triangle, and a triangle shades less once the sides curve. New concrete posts are a building job. Measure from anchor to anchor, then leave about 30–60 cm so ropes or turnbuckles have room. Listings here also say 1.5–2 ft, or 30–45 cm on one 3 x 3 m page. The printed size is often the distance between the corner tips. One UK review of a 2 m side measured 1.42 m across the middle.
Fabric, water and the review sample
HighCoated polyester or Oxford is the waterproof claim in this set: 300D, 420D, or about 160–180 g/m². Read it with the heavy-rain line. A flat coated sail holds water. One title says waterproof, then a 400 mm head and the words not waterproof. One 3 x 3 m page says waterproof in the bullets and water resistant in the attribute. Two pages limit the cloth to light and moderate rain. The 120 g/m² polyethylene sails are the breathable cloth.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Summer shade, rain may pass
You want sun block where rain may pass through, and you already have hooks within a short rope’s reach. Count the cream and grey KAHEIGN review text once.
Three anchors only
You have three fixing points, so a rectangle will not sit. This triangle lists three ropes. It has no stored reviews, and the dimensions attribute says 10 x 10 mm. Do not pick a size from one ABTZENO field.
Common questions about sun sails
Which sun sail is the top pick in this set?
The top pick is the Mokani 3 x 4 m grey rectangle at about £41.99. It is 4.3 from 672 amazon.co.uk reviews, the highest star line here among sails with hundreds of reviews, and the stored score is 80. The box includes turnbuckles, pad eyes, plugs, six ropes and a bag. The centre can stay saggy, rain can sit in the belly, and continuous heavy rain may still seep.
Which listing is the best value?
The best value is the HEYOMART cream 2 x 2 m square at about £19.99. It is 4.0 from 1,575 reviews, a large sample of its own, and the stored score is 70. The cream KAHEIGN is about £18.99 and scores 68, but that review text is the same as the grey KAHEIGN, so it is not a second sample. HEYOMART’s title says waterproof; the bullets state a 400 mm head and say it is not.
How much does a sun sail cost in this set?
On the stored amazon.co.uk figures these twelve listings run from about £12.99 to about £41.99. Under about £21 sit ABTZENO, the cream KAHEIGN, the DAJAVE triangle and HEYOMART. From about £22 to £33 sit both YOUNTHYE sails, Ghligna, the grey KAHEIGN, RICHIE, the Mokani 3 x 3 m and the DAJAVE rectangle. The top of this set is the Mokani 3 x 4 m at about £41.99.
Will a coated sun sail keep heavy rain off?
A flat coated sail holds water. These listings warn about heavy rain even when a bullet says waterproof. The Mokani 3 x 3 m bullets say waterproof and the attribute says water resistant. HEYOMART’s title says waterproof and the bullets say it is not. A KAHEIGN review says the cloth is certainly not waterproof. DAJAVE limits itself to light and moderate rain. Take it down before a gale. Do not stand under a coated sail that is holding rain.
How should I measure the shaded patch?
Measure anchor to anchor, then leave about 30–60 cm, or the 1.5–2 ft some listings ask for, so the ropes or turnbuckles fit. The stated size is often corner to corner, not the width of the belly. Reviewers describe a 2 m by 3 m sail shading about 1.4 m by 2.4 m, and a 2.5 m by 3 m sail about 200 mm narrower in the middle.
Do I need planning permission in England?
England’s householder permitted development is on GOV.UK under the 2015 Order. There is no shade-sail class. The Planning Portal’s awning FAQ treats a freestanding awning as an outbuilding and an attached awning as an alteration. Ask the council for a listed building, a conservation area, an Article 4 direction, a flat, or new tall posts. Scotland, Wales and Northern Ireland differ. A lease can forbid a fixing. New concrete posts are a building job, not a cloth choice.
Does a UV percentage replace sun protection?
No. A seller’s 95 or 98 percent UV line is not an NHS certificate. From March to October, use shade between 11am and 3pm, protect skin when the UV index is 3 or higher, keep babies under 6 months out of direct sun, and do not rely on sunscreen alone. UV can still pass gaps and reflect off the ground. A three-anchor cloth is a different comparison: triangle shade sail.
Our verdict
In this set the top pick is the Mokani 3 x 4 m rectangle: stored score 80, 4.3 from 672 reviews, about £41.99, and the only listing that ships turnbuckles, pad eyes, plugs, six ropes and a bag. The centre can stay saggy and rain can sit in the belly. The best value is the HEYOMART 2 x 2 m square at about £19.99, score 70, 4.0 from 1,575 reviews of its own. The cream KAHEIGN is about £18.99 and does not take that badge: the review text is shared with the grey ASIN and the score is 68. The Mokani 3 x 3 m scores 78 from 2,002 reviews and does not take the top pick: the stored scores put the 3 x 4 m listing first.
