External pocket sliding doors in Corby: what to know
These are the points a surveyor will go through with you when you choose external pocket sliding doors for a home in Corby:
Want the whole width of your Corby 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 Corby extension still at the drawing stage, planning the pocket wall now is far simpler than rebuilding a finished wall later.
- A lined and drained pocket carries rainwater running along the track out of the wall, protecting the structure as well as the rollers.
- 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.
- A removable access panel on the inside of the pocket wall lets the rollers be reached and adjusted without opening up the plaster.
How much sun will a door in Corby get?
Sun angles matter for big glazed doors. Around Corby, midday sun reaches about 61° in summer and drops to about 14° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.
What should you budget for external pocket sliding doors in Corby?
These figures are for the door supplied and fitted, with the engineer's structural calculations, including VAT. They include forming the opening and the pocket in the wall; Building Control fees are set by your council and are extra. Your price is fixed in a written quote after survey.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 1.8 m | 1 panel | £6,595–£8,095 |
| 2.4 m | 2 panels | £7,495–£9,195 |
| 6.0 m | 3 panels | £12,895–£15,795 |

Survey, manufacture and fitting around Corby
Nothing is ordered until you sign off the surveyed specification. The door is made from the finished opening sizes (typically 6–8 weeks from survey sign-off), and fitting usually takes 3–5 days of building work to form the opening and pocket, then 1–2 days to fit the door. If you are in Uppingham or Desborough, the same process and prices apply.
Do you need approval in Corby?
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.

Questions about external pocket sliding doors in Corby
Is the price different in Corby?
No. Guide prices for external pocket sliding doors are the same across mainland Britain, including Corby. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
How much do external pocket sliding doors cost?
External pocket sliding doors start from a guide price of £6,595 for a 1.8 m single-panel door, fitted, inc VAT, at standard 2.1 m height, including forming the wall pocket. A 3 m two-panel door is a guide £8,395–£10,295, and a 6 m three-panel door is around £12,895. Wall construction, glass and finish affect the figure, which is fixed in a written quote after survey.
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.
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.
