IKEA and flat-pack furniture assembly in London: the 2026 guide.

A flat-pack box looks simple on the shop floor and considerably less so at 9pm on the living-room carpet, surrounded by cam locks, dowels and a wordless manual. IKEA flat-pack assembly in London carries an extra layer of difficulty most buying guides skip: the flat itself. This is a practical guide to furniture assembly in London in 2026 — what a good service actually builds, how long each piece really takes, and why a Victorian conversion in N16 turns the same PAX wardrobe into twice the job it would be in a Home Counties new-build.

What an IKEA assembly service actually builds

Most bookings fall into a handful of categories. An IKEA assembly service spends its weeks on bedroom storage above everything else — PAX wardrobes (frames, hinged and sliding doors, KOMPLEMENT internals), MALM and HEMNES chests, and bed frames from MALM up to the taller BRIMNES with underbed drawers.

Beyond the bedroom, the regular list runs to:

• Bunk beds and high sleepers — MYDAL, STUVA and non-IKEA equivalents, the fiddliest common build
• Desks and home-office kit, from a plain LAGKAPTEN top to motorised sit-stand frames
• KALLAX and BILLY shelving runs, often wall-anchored across an alcove
• Kitchen units — IKEA METOD carcasses, drawers and door alignment (cabinetry, not plumbing)
• Garden and balcony furniture — the summer rush, usually softwood sets and rattan-effect sofas

The same crew handles Wayfair, Made, Habitat and Argos flat-pack too. Non-IKEA boxes vary far more in quality, which affects both time and price. The full breakdown lives on our furniture assembly London page.

How long each piece really takes

Manufacturer "assembly times" assume a clear floor, every part present and someone who has built the model before. Real timings for one experienced assembler tend to look like this:

• BILLY bookcase — 20 to 30 minutes
• KALLAX 4x4 — 30 to 45 minutes
• MALM bed or chest — 45 to 90 minutes
• HEMNES dresser — around an hour
• PAX wardrobe, single frame with doors — 1.5 to 2.5 hours; sliding doors add time for alignment
• Bunk bed or high sleeper — 2 to 3 hours
• Sit-stand desk — 45 to 60 minutes
• A run of METOD kitchen units — most of a day

Two things blow those figures out: missing or damaged parts (check the manifest before opening the sealed fittings bag), and access — the subject of the next section.

Why London flats make flat-pack fiddly

Flat-pack furniture assembly in London is rarely about the box and usually about the building. Three things separate a smooth build from a lost afternoon.

Walls. IKEA supplies an anti-tip restraint with every tall wardrobe and chest, and fixing it correctly is not optional — it is the difference between safe and dangerous furniture. What the wall is made of decides how. Victorian and Edwardian conversions across Hackney, Camden and Tooting are usually solid brick or lath-and-plaster: brick takes a masonry bit and a proper plug; lath-and-plaster needs care to find a joist. Post-2000 new-builds in Nine Elms, Stratford (E20) and Canary Wharf are typically plasterboard on metal studs, or dot-and-dab board over blockwork with a void behind — the wrong fixing there pulls straight out. A PAX anchored into a stud, a spring toggle or the brick behind the void is secure; a screw in bare plasterboard is not.

Getting the box in. Narrow Victorian stairwells, tight half-landings and lift-free walk-ups in N1, SW11 and NW6 mean a 2.4m PAX frame sometimes cannot be turned at the top of the stairs — so it is built flat and walked upright into place, which needs floor space and a second pair of hands. Mansion blocks and new-builds may have a lift, but check whether it is a small passenger lift or a goods lift that has to be booked ahead.

The van and the kerb. If we collect the flat-pack for you, ULEZ, the Congestion Charge and controlled parking zones all apply. A suspended bay or a permit-only street in Islington or Kensington needs planning — there is no loading on a red route.

Assembled by a pro, or do it yourself?

Self-assembly is genuinely fine for a BILLY or a KALLAX on a free Saturday. The calculation changes with weight, height and anything that anchors to a wall. A PAX is heavy, unforgiving of a single misread diagram, and easy to rack out of square so the doors never sit flush. Bunk beds carry a child's safety on the fixings. Kitchen units have to be dead level or every door looks wrong. If a piece is tall, load-bearing or slept in, the case for a pro is strongest — and you keep the walls undamaged and the packaging cleared.

What to check before you book

Five things make an assembly visit go cleanly:

• Have the model names or the IKEA receipt to hand — it tells the assembler exactly what is coming
• Confirm the boxes have arrived and are in the room, not still with the courier
• Keep the fittings bags sealed and together — cams and dowels are model-specific
• Flag your wall type and any lift or stairwell issue when booking, so the right fixings come in the van
• Clear roughly two square metres of floor per large item

What Hausio charges, and how booking works

Hausio prices furniture assembly from £45 an hour with a one-hour minimum, plus flat rates on the most-booked IKEA models — a PAX wardrobe from £85, a MALM bed £45, a HEMNES dresser £35, KALLAX £25 and a BILLY £20. Anything non-IKEA, or a bigger multi-item build, is charged at the same £45 an hour. For the full flat-rate list see our furniture assembly London page.

Every assembler is DBS-checked, interviewed in person and fully insured (£2M public liability, £25k goods-in-transit), and arrives with drill, hex keys, mallet, level and stud finder. Jobs inside the Central London Congestion Zone (EC, WC, W1, SW1 and SE1 postcodes) carry a flat £18 access charge; same-day slots add £15. There is £0 to pay at booking — you settle after the job by card, Apple Pay or Google Pay. Booking online takes about a minute, seven days a week, 8am to 8pm.
