Flat-pack furniture rarely goes wrong because the instructions are hard to follow. It goes wrong when a wardrobe built on its back will not stand up under the ceiling, when a cam lock is overtightened and splits the chipboard, or when a tall chest of drawers is left free-standing in a child’s bedroom. Good furniture assembly deals with those points before the first panel comes out of the box.

Voltify Contractors assembles flat-pack wardrobes, beds, drawers, desks and shelving units for homes, rental properties and offices across East and South-East London. Assembly is one part of our handyman and property maintenance service, so fixing units to the wall, adjusting doors and dealing with small jobs nearby can be handled in the same visit.
What Changes the Job, Piece by Piece
Two items with the same number of boxes can take very different amounts of time. If you are still weighing up whether to build something yourself, our guide on when professional assembly is worth it walks through the decision item by item. These are the details that matter most:
| Item | What takes the time | What to check before booking |
|---|---|---|
| Wardrobes | Door hanging and alignment, sliding door tracks, internal drawers and fittings | Ceiling height and the diagonal clearance needed to stand the frame up |
| Beds | Storage bases, gas-lift ottoman mechanisms, slat systems and headboards | Room to build it in place, especially in small bedrooms or with a fixed radiator |
| Chests of drawers | Every drawer runner has to be square or the drawers will stick | Whether a wall restraint is supplied and where it can be fixed |
| Bookcases and display units | Long back panels, adjustable shelf pins, glass doors | Wall type behind the unit if it is tall |
| Desks and office furniture | Sit-stand frames, cable trays, pedestal drawers, multiple identical units | Where the sockets are, and whether a desk will block them |
| Children’s furniture | Guard rails on bunk and cabin beds, cot sides | The manufacturer’s age and mattress guidance for that item |
Tall Furniture Should Be Fixed to the Wall
Most wardrobes, bookcases and chests of drawers now come with a wall restraint kit, and there is a good reason for it. A tall or top-heavy unit can tip forward when drawers are pulled out or a child climbs it, and the risk is highest in bedrooms.
The screws and plugs in the kit are often a basic set that suits only some walls. The fixing needs to match what is behind the plaster:
- Solid brick or block: a masonry plug and screw sized for the restraint.
- Plasterboard on studs: ideally a screw into a timber stud; if the unit sits between studs, a cavity fixing rated for the load.
- Plasterboard stuck to masonry (dot-and-dab): a fixing long enough to reach the solid wall behind the gap.
Pipes and cables run through walls, so the position of a restraint is checked before drilling. If a previous fixing has left a torn or crumbling patch of plasterboard where the unit needs to go, it can be put right first through our drywall and wall repair service.
Getting the Room Ready for Flat-Pack Assembly
A little preparation keeps the visit focused on building rather than clearing space:
- Leave the boxes in the room where the furniture will stand, unopened if you prefer, so parts are not mixed up between items.
- Clear a working area roughly the size of the largest panel, plus space to walk around it.
- Measure the ceiling height for a tall wardrobe. A frame built lying down needs enough room to be tilted upright; if the ceiling is low or has a beam, it may have to be built standing.
- Mention stairs, lifts and parking if the boxes still need carrying up to a flat or across a car park.
- Keep any online planner printout for modular systems, so the internal layout matches what you ordered.
If existing furniture has to be taken apart first to make space, say so when you book so the time can be allowed for.
Missing Parts, Damaged Panels and Wrong Deliveries
A missing bag of fittings or a chipped panel is one of the most common reasons an assembly cannot be finished. Checking the boxes against the parts list before the visit, where you can, saves a wasted trip. If a problem is found on the day, the furniture can usually be built as far as possible while you contact the retailer for the replacement part, and the remaining work finished once it arrives.
Where a hinge, drawer runner or cam fitting is simply loose on furniture you already own, that is a repair rather than an assembly job and can go on a general handyman list alongside other small jobs.
Landlords, Letting Agents and Offices
Furnished lets often need several rooms assembled between tenancies, usually to a deadline set by the move-in date. For rental properties, assembly can be booked alongside other void-period work through our landlord property maintenance service.
For offices, the job is often a run of identical desks, pedestals and storage units, sometimes on a floor that is still in use. Planning the order of work and where the empty packaging will be stacked matters as much as the assembly itself. Larger fit-outs and ongoing work for managed buildings are covered by our commercial property maintenance service.
When the Furniture Needs Other Work Around It
Assembly sometimes shows up something else that needs attention. A new wardrobe or desk may cover the only double socket on that wall, or a room may need painting before fitted-looking furniture goes in. Those are separate jobs, handled through our electrical services and painting and decorating services, and it is easier to plan them before the furniture arrives than after. If a TV is going on the wall above a new media unit, TV mounting can be booked on the same visit so the unit and screen line up.
Cost of Furniture Assembly
The documented minimum call-out is £80 for the first hour. The total depends on the number and size of items, how complex they are (a sliding-door wardrobe with internal drawers takes far longer than a bedside table), whether units need fixing to the wall, and how easy it is to get the boxes into the room. A list of the items with product names or links gives the most accurate idea of time before the visit.
Standard visits run 7am–5pm, Monday to Friday. Send your list and contact Voltify Contractors to arrange assembly, or check the areas we cover across East and South-East London.
