What external pocket sliding doors offer homes in Radlett
The right door depends on the opening, the room and the way you use the garden. Here is how external pocket sliding doors tend to work out in practice:
If the only wall beside your Radlett opening is shared with a neighbour, check the pocket design and any steel bearing on it early, as the Party Wall etc. Act 1996 (England and Wales) may apply.
Want the whole width of your Radlett 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.
- Parked inside the wall, open panels are protected from weather and knocks, and garden furniture can sit right up to the edge of the opening.
- 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.
- When closed, a pocket door looks like a large-paned slider, with slim meeting stiles and plenty of glass instead of the many frames of a folding door.

Survey, manufacture and fitting around Radlett
A surveyor visits your Radlett home to check the wall, the structure above and the floor levels, and talks through glass and finish. Any building work is planned to the engineer's design, the door is made to 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.
Rules for external pocket sliding doors in England
In England, forming or widening an opening is structural work that needs a Building Regulations application, structural calculations and usually a steel beam on padstones. The new door is also a controlled fitting (U-value 1.4 W/m²K or better if more than 60% glazed). If steelwork bears on a party wall, the Party Wall etc. Act 1996 may apply.
Options to consider for your external pocket sliding door
- Threshold. Low or flush thresholds, with the external drainage channel continuing past the pocket.
- 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.
Questions about external pocket sliding doors in Radlett
Do you fit external pocket sliding doors in Radlett?

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.
Do external pocket doors need Building Regulations approval?
External pocket doors need Building Regulations approval in England, because forming the opening and pocket is structural work needing an application, structural calculations (included in our guide prices), and usually a steel beam or lintel. If the steel bears on a party wall, the Party Wall etc. Act 1996 (England and Wales) may apply. Scotland needs a building warrant; Wales and Northern Ireland have their own building control rules.
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.
