Four different things called copper pipe

Plumbing tube is the seamless stick a 15 mm, 22 mm, or 28 mm fitting expects. Craft offcuts are short pieces, often 100 mm to 300 mm. A soft coil should name its own standard. A brake line is usually copper-coated steel or plated iron with flare nuts. Only one family belongs in the basket. In this set the plumbing-shaped row is PlumbUniverse: 15 mm, 1 m, £9.49, rated 4.4 from 164 reviews. It allows solder-ring, compression, and water-only push-fit, and it does not state BS EN 1057. The sourcing map rows are 100 mm and 200 mm. The METERXITY packs are 5 mm and 10 mm. The BRRNOO coil is titled 1/2 inch and 2 m. Diameter for a domestic run sits on 15 mm or 22 mm copper pipe.

What a plumbing length should say

BS EN 1057 covers seamless copper tube for water and gas in sanitary and heating use. Trade straight tube is usually half-hard R250. Table X, the light wall, is 15 × 0.7 mm, 22 × 0.9 mm, and 28 × 0.9 mm. Lawton’s 2026 brochure says domestic straight lengths are stamped with size, a Kitemark, EN 1057, temper, maker, and quarter. None of the ten listings prints that set. A different amazon.co.uk ASIN, B08LTWPHCS, does state BS EN 1057 R250 and 15 × 0.7 mm, and it is not one of these rows. Do not paste that stamp onto the £9.49 metre. If the amazon title is silent, you do not have that mark. A 1 mm craft wall is not Table X at 0.7 mm. The named picks are on best copper pipe.

Length in millimetres, then price

100 mm is 0.1 m. 200 mm is 0.2 m. 300 mm is 0.3 m. The sourcing map 100 mm tube is £5.39 and the 200 mm tube is £8.02. Both show 4.3 from 273 and the same review text, so that count is one pool. On the Screwfix page checked for this research, Wednesbury 15 mm × 3 m was £15.60 including VAT and cited EN 1057. A separate 15 mm × 2 m page was £9.38. The amazon metre at £9.49 can cost about as much as two metres of Kitemarked tube.

Where DIY stops

A competent householder can joint copper on wholesome water or closed heating. The Gas Safety (Installation and Use) Regulations 1998 require competence, and HSE says domestic gas work is for a Gas Safe registered engineer. Stop as well for a brake line or a refrigerant coil you would have to braze.

Common questions

Is 100 mm the same as a metre of 15 mm pipe?
No. 100 mm is 0.1 m. The sourcing map listing at £5.39 is a 100 mm offcut, and the 200 mm listing is 0.2 m. Reviews in the shared 4.3-from-273 pool often say the buyer expected a much longer piece. Read the title in millimetres before you compare it with the £9.49 one-metre pipe.
What should be printed on plumbing copper?
Lawton’s brochure describes domestic straight lengths stamped with size, a Kitemark, EN 1057, temper, maker, and quarter. Yorkshire writes the size as outside diameter times wall, with R250 the usual half-hard stick. None of the ten listings prints that set. A stamp you cannot see is not a standard you can claim.
Is Table X the same as BS EN 1057?
BS EN 1057 is the standard for seamless round copper tube for water and gas in sanitary and heating use. Table X is the light wall in that family: 15 × 0.7 mm, 22 × 0.9 mm, and 28 × 0.9 mm. A listing can be silent on both. Silence is not Table X, and a 1 mm craft wall is a different tube.
Why is a short amazon tube close to the price of a 3 m stick?
You are paying for a packed short length, not for copper by the metre. The 1 m listing is £9.49. The Screwfix Wednesbury 15 mm × 3 m page checked here was £15.60 including VAT, and a 2 m page was £9.38. Those prices move. They are context, not a promise that today’s basket will match.
Can I use a craft 10 mm or 5 mm tube on a tap?
No. A tap tail or a short radiator branch in this job is 15 mm outside diameter, and the trunk is often 22 mm. The 10 mm pack is three 300 mm tubes with a 1 mm wall. The 5 mm pack has a 0.2 mm wall that a UK review says folds when bent. Neither listing confirms plumbing use.
Does a listing that mentions gas mean I can fit gas pipe?
No. The Health and Safety Executive treats domestic gas fittings as Gas Safe work under the Gas Safety (Installation and Use) Regulations 1998. A product bullet is not a registration. Use a Gas Safe engineer for gas, including a repair on an existing gas pipe.
