Best back box for plasterboard

Updated: October 2026

You already know you need a back box, and you want one of the three amazon.co.uk listings for the wall you actually have. The best back box for plasterboard is not the one with the most stars if that box is a metal chase fitting, and the cheapest metal box is the wrong buy if the wall is a hollow stud. The [Wall box comparison](/hub/electrical-equipment/wall-box) is the table for Lyvia, LEENUE, and Evoges, with the prices and review counts saved on 21 October 2026. How to choose the order of wall, depth, and gang, before you pick a row, is on the [buying guide](/hub/electrical-equipment/wall-box/sub/wall-box-buying-guide).

You already know you need a back box, and you want one of the three amazon.co.uk listings for the wall you actually have.

Our top picks

On this page

For plasterboard, start with the Evoges dry lining box

The Evoges EDB1G35, ASIN B0FWCHV232, is the only box in this set described as a dry lining fit for plasterboard or a hollow wall. It is listed at £8.99, 35 mm deep, with spring lugs the bullets call tool-free, and 4.7 from 60 amazon.co.uk reviews. That is the highest star line here and the smallest sample, so it is the top pick for a hollow board, not a test winner. The bullets state UKCA and a flame-retardant material. Skip it for brick, for a job that needs a stated earth terminal, or for a fire-separating wall. If the plate depth is the open question, use 25 mm or 35 mm before you assume 35 mm is what your USB module needs.

For a chased solid wall, the Lyvia 25 mm metal box

The Lyvia box, ASIN B013K0WOGO, is the flush metal row: one galvanised 1-gang pattress listed at £3.68, with 4.6 from 224 reviews, the largest sample in the set. The bullets say 25 mm, knockout cable entries, an earth fixing connection, and compatibility with 1-gang faceplates. It is the best value here on price and review count when you are chasing a solid wall for a standard 25 mm plate. It is not the best value if the earth lug is the part you must trust without looking. One UK review says the brass point was extremely thin and sheared on first use, which leaves that terminal unusable. The listing also prints 7 × 7 × 7 cm in the technical details, which conflicts with 25 mm, so measure before you cut a 70 mm chase.

For a plate on the face of the wall, the LEENUE 32 mm surface box

The LEENUE box, ASIN B091C91XV6, is the surface pattress: white ABS, 86 mm × 86 mm × 32 mm, listed at £6.99, with 4.6 from 149 reviews. The bullets name brush plates and network plates, including Cat5 and Cat6, plus TV, phone, and audio plates. Reviewers describe the 86 mm footprint as accurate for a UK single-gang Cat6 faceplate, and 32 mm as enough to avoid a tight bend on a keystone. That is the row to use when the plate has to sit on the wall because you cannot chase. The pack is one box and two screws. Wall plugs are not listed, and one review says they were missing. The faceplate is not included. The specification does not state an earth terminal, a British Standard, or UKCA.

When none of the three is the right buy

All three listings are 1-gang. A double socket, a cooker switch, or a 2-gang plate needs a wider box, and no star line on a single changes that. None of them states an IP rating. The Evoges bullets specify plasterboard, the Lyvia page does not answer a weatherproof question, and the LEENUE page does not claim outdoor use, so a garden socket is a different product, often an IP65 assembly rather than a bare pattress. A fire-separating wall is also outside this set. If you are still unsure whether the wall is masonry or a stud, settle that on metal or dry lining before you add a box to the basket.

Common questions

Which of these is the plasterboard box?
The Evoges EDB1G35 is the plasterboard box in this set. It is a 35 mm dry lining box with spring lugs, listed at £8.99, and the bullets name a hollow wall. The Lyvia box is a galvanised flush pattress for a chase. The LEENUE box is a 32 mm surface pattress. Putting the metal box behind plasterboard leaves you with no solid fixing, and the surface box does not sit inside the board at all.
Is the cheapest metal box the one to buy for brick?
The Lyvia box is the lowest price in this set, at £3.68, and it is the flush metal listing, so it is the brick-and-block row if you accept 25 mm and you check the earth lug. One review reports the brass earth point shearing on first use. Cheap, in this table, means the Amazon shelf price against the other two ASINs. It does not mean the lug or the 7 cm dimension line can be ignored.
Which box is for a Cat6 faceplate on the surface?
The LEENUE 32 mm surface box is the one whose listing names Cat5 and Cat6 faceplates and whose reviews describe an 86 mm fit. You still buy the faceplate separately, and you still buy wall plugs if you are screwing into masonry. It is not a flush box and it does not claim a British Standard number. Use it when the cable can enter a box that stands proud of the wall.
Is the Evoges pack five boxes or one?
The title says pack of 5 and the bullets also mention a 1 or 5 pack. The technical details say number of items 1, which may mean one pack or one box. The listing does not settle it. Count what arrives before you mark five holes, and do not turn £8.99 into a firm price per box until the carton confirms five.
Should I skip all three and buy a trade-counter box?
You should if you need a BS 4662 or BS 5733 mark you can read on the moulding, a published plasterboard range, or a counter price below these Amazon rows. Appleby-style dry lining boxes are the trade default in that conversation. They are not these ASINs. Stay with this set when the mounting matches your wall and you have read the gaps on the listing.
