Are external pocket sliding doors right for your Sevenoaks home?
Most homeowners choosing external pocket sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Want the whole width of your Sevenoaks kitchen open to the garden but prefer the look of sliders to bifolds? A pocket gives you both, at the cost of more building work.
For a Sevenoaks extension still at the drawing stage, planning the pocket wall now is far simpler than rebuilding a finished wall later.
- Pockets can be formed on one side or both, so a wide opening can part in the middle with panels sliding away in each direction.
- Open panels are hidden inside the wall rather than stacked in view, keeping the opening clean-lined compared with a bifold stack at one side.
- With every panel slid into the wall, the full width of the opening is clear, so the room and terrace join without a fixed panel in the way.
Planning glass for the light in Sevenoaks
In Sevenoaks the shortest day has roughly 7 h 52 min of daylight and the longest about 16 h 36 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

How fitting works in Sevenoaks
Here is the usual sequence in Sevenoaks: guide price, free survey, written quote, any building work, then manufacture (typically 6–8 weeks from survey sign-off). Fitting typically takes 3–5 days of building work to form the opening and pocket, then 1–2 days to fit the door. Nearby, we also survey in Westerham, Tonbridge and Orpington.
Do you need approval in Sevenoaks?
A new or wider opening in England needs Building Control approval for the structural work as well as compliance for the door itself under Approved Documents L and K. Expect structural calculations, a steel beam and, where a party wall is involved, notices under the Party Wall etc. Act 1996.
Which options matter for external pocket sliding doors?
- Colours. Single or dual colour powder coating, so the exposed edge of the panel matches the frame inside and out.
- Pocket side. A single pocket to one side, or pockets on both sides so a wide door parts in the middle.
- Internal finish. Plastered, panelled or tiled finishes on the pocket wall, with the access panel set discreetly into it.
Questions about external pocket sliding doors in Sevenoaks
How soon can you survey in Sevenoaks?
Surveys in the TN13 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 6–8 weeks from survey sign-off.
How much wall do I need for an external pocket door?
An external pocket door needs a clear length of wall beside the opening at least as long as the panels that slide into it, plus a little for the frame. For a single 2 m panel that means just over 2 m of wall with no windows, radiators, sockets or pipes in it. A two-sided pocket splits the panels between both sides, so each side needs less length.
Are external pocket doors secure?
External pocket doors are secure when the panels lock to the frame with multi-point hardware, the glass is laminated, and the pocket is closed off so the panels cannot be reached from outside. Once shut, the front edge of the panel locks into the frame just as on a standard slider. Systems are available tested to PAS 24, and the locking specification is set out in your quote.
Does a pocket in the wall cause heat loss?
A pocket in the wall does not have to cause significant heat loss if it is insulated, lined and sealed as part of the design, and the door itself typically achieves whole-door U-values around 1.2–1.6 W/m²K double glazed. In England, a new door in an existing home with more than 60% glazing must achieve 1.4 W/m²K or better. Wales, Scotland and Northern Ireland have their own energy rules.
