Top tips
Hiring a doors, without the regret.
Four moves that separate a smooth job from a nightmare.
Cassette racking
If the cassette twists during install, the door will bind. Always pack the cassette to the surrounding studs every 200mm.
Plasterboard damage
The cassette's plasterboard cladding is fragile — bashed during plumbing or first fix, it dents into the door cavity.
Fixing into the cassette wall
You can't hang a heavy picture on a pocket-door wall — there's nothing behind the plasterboard skin. Mark the wall and warn the homeowner.
Door slab thickness
Standard cassettes take 40mm doors. Thicker slabs (45mm, 50mm) need the cassette specified at order.

Doors explained
Pocket doors slide into a hidden cassette inside the wall, giving a completely uninterrupted opening when open and a clean wall when closed. They free up swing space and look architectural. Expect to pay £900–£3,500 fitted in the UK including the cassette kit.
What Does the Work Involve?
The pocket-door cassette is a factory-built steel-and-timber frame that gets built into a stud wall. In new construction it is straightforward — the carpenter cuts in the cassette during first fix, the plasterer dot-and-dabs over the metal cladding, and the door is hung at second fix. In retrofit, the existing wall is opened, studs cut, the cassette dropped in, the wall thickened to 120–130mm to accommodate it, and replastered and decorated. The door slab hangs on top-running ball-bearing wheels and slides into the cassette with a soft-close at the end of travel.
Typical Costs
| Item | Low (£) | High (£) | Notes |
|---|---|---|---|
| Eclisse Classic kit (single) | 280 | 480 | UK best-seller |
| Coplan PD75 kit | 320 | 520 | Heavy-duty 100kg system |
| Double-pocket kit | 500 | 900 | Two doors meeting centrally |
| Door slab, supply | 180 | 700 | Stock or bespoke |
| Soft-close upgrade | 70 | 180 | Both ends of travel |
| Carpenter labour | 350 | 600 | One day on new build |
| Retrofit (wall opening + plaster) | 800 | 1,800 | 3–5 days total |
How Long Does It Take?
New-build first fix: one day. Retrofit: 3–5 days including plastering, drying time, and decoration.
DIY or Professional?
Professional. The cassette has to be installed dead plumb, dead square, and packed against the surrounding studs so it doesn't move when the wall is plastered. A 2mm twist will leave the door binding in the wall — a problem that's near-impossible to fix without opening the wall back up.
Choosing the Right Tradesperson
Use a carpenter who has fitted Eclisse or Coplan systems before — they have specific tolerances and quirks (e.g. shimming the head rail before plastering). Ask to see previous work, including operating the door — it should glide silently with soft-close at both ends.
UK Regulations
Pocket doors in load-bearing walls need a structural engineer's lintel calc. Standard pocket-door cassettes do NOT meet FD30 fire-door requirements; specific FD30-rated pocket cassettes exist but are 3–5x as expensive. Internal doors don't need building-regs notification otherwise.
Common Problems
- Cassette racking: If the cassette twists during install, the door will bind. Always pack the cassette to the surrounding studs every 200mm.
- Plasterboard damage: The cassette's plasterboard cladding is fragile — bashed during plumbing or first fix, it dents into the door cavity.
- Fixing into the cassette wall: You can't hang a heavy picture on a pocket-door wall — there's nothing behind the plasterboard skin. Mark the wall and warn the homeowner.
- Door slab thickness: Standard cassettes take 40mm doors. Thicker slabs (45mm, 50mm) need the cassette specified at order.
Frequently Asked Questions
Can a pocket door be retrofitted into an existing wall?
Yes — but it adds 3–5 days of building work and £600–£1,500 to the cost. The wall thickness must be increased to 120–130mm.
Can you hang pictures on a pocket-door wall?
No — there is no stud behind the plasterboard within the door's travel zone. You can hang lightweight pictures using No More Nails or 3M Command strips, but anything that needs a fixing must avoid the pocket zone.
Are pocket doors as quiet as hinged doors?
With ball-bearing rollers and soft-close, yes — quieter, in fact, because they don't slam shut. Cheap systems with nylon rollers click and rattle.
Can pocket doors lock?
Yes — flush-fit privacy locks (with an emergency coin-release outside) are standard. Hook bolts engage into a strike in the jamb.
What's the difference between Eclisse and Coplan?
Eclisse is the UK market leader — well-documented, easy to fit, sub 100kg doors. Coplan is heavier-duty (up to 200kg leaves) and used for full-height architectural slabs. Both have good warranty support.
Can two pocket doors meet in the middle?
Yes — double-pocket configurations give a 2.4m+ unobstructed opening. The two leaves meet at the centre with a soft-close strike between them.
