How much does flat pack furniture assembly cost?
Updated 19 Oct 2026
Typical cost per item
£30 – £60
Flat pack furniture assembly in the UK typically costs £30–£60 per item, with discounts when several pieces are built in the same visit. Most assemblers work either per item or at an hourly rate of £25–£45. The single biggest saving available is batching everything into one booking, since travel and setup are charged once rather than per item.
| Job | Typical cost |

| Standard item (desk, drawers, shelving) | £30 – £60 |
| Bed frame | £40 – £80 |
| Wardrobe | £60 – £120 |
| Kitchen unit, each | £40 – £80 |
| Hourly rate | £25 – £45 |

Per item or by the hour?
Per item is the norm for one or two pieces, and it is the safer option for you: if the build turns out awkward, that is the assembler's problem rather than your bill.
Hourly at £25–£45 usually wins once you have several items, or a mix of assembly and other small jobs. A full bedroom of furniture is often best done as a half or full day.
Whichever applies, send a list of exactly what needs building when you book — ideally with the product names. An assembler who knows they are facing three specific units can bring the right tools and give you a realistic time, rather than discovering a wall-mounted unit that needs different fixings.
Ask about a minimum charge. Most have one, typically an hour, which is why a single small item can cost nearly as much as two.
Wall fixing is the part that matters
Tall furniture — wardrobes, bookcases, tall drawer units — must be fixed to the wall. Flat-pack furniture is light and top-heavy, and it tips forward easily, particularly when a drawer is open or a child climbs on it. Almost every unit ships with a bracket or strap for exactly this reason.
The fixing in the box is usually a basic plug and screw, and it is often wrong for the wall you have. Plasterboard needs a proper hollow-wall anchor landing in a stud where possible; masonry needs the right plug and drill bit.
Tell the assembler what your walls are when you book, and confirm anchoring is included. Most do it as standard, but it is worth saying rather than assuming.
If you are assembling yourself, this is the step not to skip. It takes five minutes.
Before they arrive
Leave the boxes sealed. It is tempting to make a start, but loose fittings go missing and a half-built unit takes longer to finish than an untouched one.
Get the boxes into the right room. Most furniture cannot be carried through a doorway once assembled, so it has to be built where it lives. Clear enough floor space to lay the panels out flat.
Check the boxes are all there. Large items often ship in two or three boxes, and discovering box two of three is missing when someone is standing in your bedroom is an expensive way to find out.
Decide where it is going. Moving a built wardrobe across a room is a two-person job and is not always possible at all.
How to keep the cost down
Do everything in one visit. This is far and away the biggest lever — the second item costs a fraction of the first.
Ask for a price for the whole list rather than adding up per-item rates.
Book a half day if you have four or more items, which usually works out below the per-item total.
Have the boxes in the right rooms and the space cleared before they arrive.
And get a couple of quotes. Assembly is straightforward work with a wide spread of prices, and posting the list locally costs nothing.
Frequently asked questions
How much does flat pack assembly cost?+
£30–£60 per item typically, with beds £40–£80 and wardrobes £60–£120. Hourly rates run £25–£45.
Is it cheaper to have several items built at once?+
Considerably. Travel and setup happen once, so most assemblers take £10–£20 off each additional item, and a half day beats per-item pricing past about four items.
Should I unpack the boxes first?+
No — leave them sealed. Loose fittings go missing easily, and a partly started build takes longer to finish than an untouched one.
Will they fix furniture to the wall?+
Most do as standard, and tall furniture should always be anchored. Tell them whether you have plasterboard or masonry walls, because the fixing supplied in the box is often not right for either.
Can they build it in a different room and move it?+
Usually not. Most assembled furniture will not fit through a doorway, so it has to be built where it will stand. Get the boxes into the right room beforehand.
Is there a minimum charge?+
Usually about an hour, which is why one small item can cost nearly as much as two. Batching is the way around it.
