The best gutter guards, compared.
Top pick: PATIKIL stainless dome Best value: LAOJU aluminium strainer – About £6.99 for four strainers, score 90 and 4.5 from 516 reviews. The file does not print 68 mm. Updated 23 October 2026.
Gutter protection is a leaf guard at the downpipe outlet, or a mesh over the trough, so leaves and twigs do not fill the pipe. It is not a length of gutter and it is not a bristle brush. You buy one in the UK when a domestic rainwater run keeps blocking after leaf fall. The usual house system is a half-round gutter about 112 mm wide with a 68 mm round downpipe. You tell a suitable guard by the opening you measured, in millimetres, and by whether that hole is round or square. An outlet insert keeps debris out of the downpipe. A trough mesh tries to keep debris out of the gutter. A balloon does not empty the trough, and moss on a mesh can send water over the front lip. A size stated in inches, a cap near 45 mm, or a dome near 61–66 mm is a different product from a stated 68 mm round hole. What to measure, and which type does which job, is set out in the [gutter protection buying guide](/hub/diy-supplies/gutter-protection/sub/gutter-protection-buying-guide).

Question 1 of 2
Where does the debris need to stop?
The PATIKIL listing pta231206tt000919eu is one 304 stainless dome at £9.99, stated for 2.4–2.6 inch, with a compatible-diameter field of 2.5 inches. That band is about 61–66 mm, and the file does not print 68 mm, so it sits short of a typical 68 mm round outlet unless your measured hole is inside that inch range. The star line is 5.0 from 2 amazon.co.uk reviews, and the score is capped at 60 because the saved count is under 10. The one UK text says the quality is excellent, it looks good, and it is adjustable, and it does not state a fault. Two ratings cannot carry a house decision. The listing says you measure the inner size and push the dome in, with no tools. The piece weighs 50 g, the footprint is 6.9 by 6.9 cm, and the capture rank is 637 in Gutters & Accessories.
Pros
Cons
Best for: You have measured an inner hole inside 2.4–2.6 inch and you only need one dome.
Less suitable: A 68 mm outlet you have not checked, or any choice that treats two 5-star ratings as a large sample.
Specifications
Common questions
What size is printed?
2.4–2.6 inch, and a compatible-diameter field of 2.5 inches. The file does not print 68 mm.
How does the listing say it fits?
Measure the inner size and push it into the hole. The note says no tools are required.
What does the copied review say?
The listing total is 5.0 from 2 reviews. The one UK text says the quality is excellent, it looks good, and it is adjustable. It does not state a fault.
The DIVCHI HA866 listing is a plastic mesh roll stated as 5 m by 15 cm, with eight fixing stakes, at £11.99. It sits in the gutter trough, which is a different job from an outlet balloon, and the bullets say you cut it to length and shape it to the gutter section. They do not name a 112 mm half-round profile, and 15 cm is wider than that typical trough, so the cut is part of the fit. The star line is 5.0 from 1 amazon.co.uk review, no review text is saved in the file, and the score is capped at 60. One rating with no words is not evidence that the stakes hold in wind or that moss will not mat on the mesh. Weight is not stated. The capture rank is 84 in Gutters & Accessories, and the date first available is 1 September 2026.
Pros
Cons
Best for: You want a trough cover you can cut, and you will not treat one star rating as proof.
Less suitable: A blocked downpipe only, or a choice that needs a review sample before you pay £11.99.
Specifications
Common questions
What is in the pack?
A plastic mesh roll stated as 5 m and 15 cm wide, plus eight fixing stakes.
Does it name a gutter profile?
No. The bullets say cut it to length and shape it to different gutter sections. They do not name 112 mm half-round.
What do buyers say in this file?
The listing shows 5.0 from 1 review. No review text is saved in the file.
The PATIKIL listing is two 304 stainless caps at £11.99, with a stated outside diameter of 45 mm, also written as 1.8 inch, a height of 80 mm, and a grid spacing of 10 mm. That is not a 68 mm house downpipe, and the note says you match the cap to the inside diameter of the pipe. The star line is 4.7 from 9 amazon.co.uk reviews, and the score is capped at 60 because the saved count is under 10. Four UK texts say it fitted a pipe, felt strong, or was adjusted easily, and one buyer used eight caps in a retaining wall against rodents. None of those four states a breakage. A wall or a small pipe is a different job from a domestic outlet. The listing says place the cap over the pipe and adjust it by hand or with tools, and it tells you to wear gloves. The pair weighs 120 g, the capture rank is 102 in Gutters & Accessories, and the date first available is 14 November 2025.
Pros
Cons
Best for: You have measured a pipe near 45 mm, or a small opening where a cap of that diameter is the point.
Less suitable: A typical UK 68 mm round downpipe, or a trough that needs mesh along the run.
Specifications
Common questions
What diameter is printed?
45 mm outside, also written as 1.8 inch. Height is 80 mm and the grid spacing is 10 mm. The pack is two.
Does the file say it fits 68 mm?
No. The note says match the cap to the inside diameter of the pipe, and wear gloves.
What do the copied reviews describe?
Four UK texts say it fitted a pipe, felt strong, or was adjusted easily. One buyer used eight in a retaining wall against rodents. None of the four states a breakage.
The Graplan GLW-SY listing is an aluminium-alloy set at £10.59, and the bullets say a 2-inch to 4-inch drainage pipe or gutter downpipe. The title says six mesh guards and six zip ties. The included-components line says four gutter leaf protections and four pull rings, and the file does not say which count arrived. Across 41 amazon.co.uk reviews the line is 4.6, which scales to 92, the highest number in this table. The nine UK texts praise the fit and do not describe breakage or rust, and one buyer said the plastic ties were not required. That pack clash is why this row has no award, even with the higher star score: a description that disagrees with itself is not a top pick. The capture rank is 4 in Gutters & Accessories, the set weighs 130 g, and the date first available is 18 August 2025.
Pros
Cons
Best for: You have measured a hole inside 2–4 inch, you will count the pieces on arrival, and you accept that the two pack lines disagree.
Less suitable: An order where the piece count has to be settled before you pay, or a listing you want to say 68 mm.
Specifications
Common questions
How many pieces does the file claim?
The title says six guards and six zip ties. Included components says four gutter leaf protections and four pull rings. The file does not say which one arrived.
What outlet size is printed?
The bullets say 2-inch to 4-inch drainage pipes and gutter downpipes.
Do the UK reviews describe a breakage?
The nine UK texts praise the fit and do not describe breakage or rust. One buyer said the plastic ties were not required.
The LAOJU LJ4XSGWUK listing is four aluminium-alloy outlet strainers at £6.99, and the bullets say the diameter can be extended up to 7.5 cm. Across 516 amazon.co.uk reviews the line is 4.5, and the score is 90. That price for four pieces, against a sample of more than 500, is why this row is the best value when you have several holes, even though the file never prints 68 mm. Reviewers say the mesh is easy to shape and that it clogs, so you still clear it. Nested pieces are hard to separate, and some strainers blew out when they were only wedged in. The bullets tell you to secure the strainer and to watch sharp edges, and no cable ties are listed, so buyers who needed them added them. The capture rank is 1 in Gutters & Accessories, the set weighs 90 g, and the date first available is 3 February 2023.
Pros
Cons
Best for: You have several outlets, you will shape the mesh to the hole you measured, and you will tie it if a wedge will not hold.
Less suitable: A hole you have not measured, or a job where you want the listing itself to say 68 mm.
Specifications
Common questions
What size does the listing state?
The bullets say the diameter can be extended up to 7.5 cm. They do not print 68 mm.
Are cable ties in the box?
No ties are listed. The bullets say to secure the strainer. Reviews mention ties that buyers added themselves.
Is there a safety line?
Yes. The bullets say to be aware of sharp edges when installing.
The Merriway BH03114 listing is a pack of two black plastic balloons at £5.25, and the title and the bullets state a 68 mm round downpipe outlet. Across 1,118 amazon.co.uk reviews the line is 4.4, the largest sample in this set, which is why the score is 88 and this row is the top pick for a measured 68 mm round hole. The bullets say you push the flexible legs into the outlet, with no tools and no separate fixings, and reviewers describe a secure fit that keeps leaves and moss out of the pipe and out of water butts. One review calls the plastic flimsy, another says the balloon was smaller than expected, and the slots still need checking so they do not silt up. It does not cover the gutter run, so a trough full of needles will still overflow even if the downpipe stays clear. The capture rank is 2 in Gutters & Accessories, the pack weighs 40 g, and the date first available is 22 September 2014. The listing does not say 65 mm square, so a square outlet is a different product.
Pros
Cons
Best for: You have measured a 68 mm round outlet and you will still look at the slots after leaf fall.
Less suitable: A square outlet, a trough that fills with needles, or a job that needs mesh over the whole run.
Specifications
Common questions
Does this listing say 68 mm?
Yes. The title and the bullets say 68 mm round downpipe outlets. They do not say 65 mm square.
Are separate fixings included?
No. The bullets say push the flexible legs into the outlet, with no tools and no separate fixings. The pack is two balloons.
Does it cover the whole gutter?
The bullets say it helps stop leaves, moss, and larger debris entering the downpipe. They do not say it covers the gutter run. Reviews in the file also say the slots need checking.
The Katai listing is four aluminium guards at £7.95, and the title says an adjustable 2–4 inch fit for round and rectangular downpipes. A compatible-diameter field on the same page says 2 inches, so the size line disagrees with itself. The star line is 3.6 from 22 amazon.co.uk reviews, and the score is 72, under the cap of 75 that applies when the saved count is under 25. The file holds three review texts, two of them from the United States, and those three do not state a fault. That is not an explanation of the other 19 ratings, and it is not UK evidence for the 3.6. The bullets say you compress the guard, insert it, and release it, with no screws, sealant, or specialist tools. The capture rank is 712 in Gutters & Accessories, and the listed weight is 70 g. Buy it only after you have measured the hole and decided which of the two size lines you are trusting.
Pros
Cons
Best for: You have measured the outlet, the piece in the photo matches that hole, and you accept a small review sample.
Less suitable: You need one agreed diameter on the listing, or a UK review set large enough to explain a 3.6.
Specifications
Common questions
What size is printed?
The title says adjustable 2–4 inch, for round and rectangular downpipes. A compatible-diameter field says 2 inches. Both lines are on the listing.
Does the listing say it is tool-free?
Yes. The bullets say compress, insert, and release, with no screws, sealant, or specialist tools.
Do the copied reviews explain the 3.6 score?
No. The file has three review texts, two of them from the United States, and those three do not state a fault. The listing total is 3.6 from 22 reviews.
Shelf prices, stars and review counts are the amazon.co.uk snapshot stored for these seven listings on 21 October 2026. The number on each card is the star line scaled to 100, then capped at 60 when the saved count is under 10 and at 75 when it is under 25. That cap stops a thin 5-star line outranking a large sample. It is not a lab test of flow, moss or how long a guard stays seated. The top pick and the best value are not the highest stored number. They follow a stated size, a large review sample and a listing that does not contradict itself. A best-sellers rank is not a test. Non-UK review text is not British opinion.
Stated opening
30%Measure the outlet in millimetres and note round or square. A title that says 68 mm is a different product from a 45 mm cap or a 2.4–2.6 inch dome. An expandable line is not the same as a printed 68 mm.
Review evidence
25%The stored score is the amazon.co.uk star line scaled to 100. Under 10 reviews the score is capped at 60. Under 25 reviews it is capped at 75. A 5.0 from one review does not outrank a large sample.
Listing consistency
20%A title and another line on the same file have to agree. Six pieces against four, or 2–4 inch against 2 inches, is a description problem. A higher star line does not wash that out.
Job and material
15%An outlet insert is not a trough mesh, and a balloon does not empty the gutter. Plastic, aluminium and stainless 304 are the labels on the file, not a lifetime claim. Sharp-edge warnings stay in view.
Price after the size matches
10%The price is the GBP figure on the saved amazon.co.uk file, and it counts only after the diameter fits. A dearer mesh is not a better buy when it is the wrong opening.
You are choosing a guard for a downpipe outlet or a mesh for the gutter trough, not a new length of gutter and not a bristle brush. The seven amazon.co.uk listings in this set run from about £5.25 to about £11.99. The usual domestic profile cited here is 112 mm half round with a 68 mm round downpipe. The top pick is the balloon whose title states 68 mm, if you have measured that hole and you will still clear the slots.
Gutter protection here means a leaf guard at the downpipe outlet or a mesh over the trough, so leaves and twigs do not fill the pipe. It is not a length of gutter and it is not a bristle brush. The usual domestic system is a half-round gutter about 112 mm wide with a 68 mm round downpipe, which is how FloPlast describes that profile. Quality is a size line that matches the hole you measured, a review count large enough to mean something, and a listing that does not contradict itself.
A 2–4 inch title, a 2.4–2.6 inch dome and a 45 mm cap are different openings. Convert nothing in your head and then assume 68 mm. The only kept listing that prints 68 mm is the balloon, and it does not say 65 mm square.
A balloon sits in the outlet. Leaves in the pipe are its job. Needles along the run can still overflow the front lip. Mesh is the trough product in this set, and you still clear moss off it.
Graplan’s title says six pieces and six ties. The components line says four and four pull rings. That clash is why the highest stored score, 92, has no award. Katai’s title says 2–4 inch and another field says 2 inches. Count what arrives.
The opening is the first check. Measure the outlet in millimetres and note whether it is round or square. A title that says 68 mm is a different product from a 45 mm cap or a dome stated as 2.4–2.6 inch, which is about 61–66 mm. Do not treat an expandable line of up to 7.5 cm as a printed 68 mm. The job is the second check. An outlet insert keeps debris out of the downpipe. A trough mesh tries to keep debris out of the gutter.
Prefer a large amazon.co.uk review count over a 5.0 from one or two reviews. The number stored for each row is the star line scaled to 100, then capped at 60 when the saved count is under 10 and at 75 when it is under 25. That cap is not a lab test, and stars are not a lab score. A listing that contradicts itself stays a problem even when the star line is higher.
Three typical situations, each with a recommendation from this comparison.
You have measured a 68 mm round downpipe and you will still check the slots after leaf fall. The Merriway pack of two is the top pick at about £5.25, with 4.4 from 1,118 reviews. It does not cover the trough, and the listing does not say 65 mm square.
You have several holes, you will shape aluminium mesh to the size you measured, and you will tie it if a wedge will not hold. LAOJU is best value at about £6.99 for four, with 4.5 from 516 reviews. The file does not print 68 mm, and the bullets warn of sharp edges.
You want a cover in the gutter run, not only a guard in the hole. DIVCHI is the 5 m plastic roll, 15 cm wide, with eight stakes, at about £11.99. The listing says cut to fit. The saved line is 5.0 from 1 review, with no review text, so the score is capped at 60.
The top pick is the Merriway 68 mm balloon at about £5.25. It scores 88. It is the only kept listing that names 68 mm, with 4.4 from 1,118 amazon.co.uk reviews. It does not cover the trough, the title does not say 65 mm square, and it is not a laboratory win. Best value is the LAOJU aluminium strainer at about £6.99, score 90: four pieces expandable up to 7.5 cm, with 4.5 from 516 reviews. The file does not print 68 mm. Reviews say wedged mesh can blow out, and the bullets warn of sharp edges. Graplan scores 92, the highest stored number, and has no award. The title says six pieces and six ties. The included-components line says four and four pull rings.
