About folding patio doors in Wandsworth
In England, replacement doors with more than 60% of the internal face glazed should achieve a U-value of 1.4 W/m²K or a Doorset Energy Rating of band C under Approved Document L. New openings in extensions are assessed with the whole extension, and large glazed areas may need energy calculations.
Bifold doors are glazed down to floor level, so every pane needs safety glass. In England, Approved Document K treats glazing in doors within 1500mm of the floor as a critical location. Units are usually toughened, with laminated glass added where extra security or protection against falls is wanted.
Aluminium is the usual material for bifold doors because its strength allows slim, stiff panels that hold heavy double or triple glazed units without distorting. uPVC bifolds cost less but have bulkier frames and suit smaller openings. Engineered timber bifolds offer a natural finish but need periodic re-coating.
Bifold doors take longer to manufacture than standard doors because each set is made to the opening and coated to order. Fitting a typical set usually takes one to two days, depending on width, removal of old doors and any making good to plaster, flooring and the patio outside.

- Coast
- Wandsworth is well inland, around 39 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Wandsworth the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. A wide bifold opening on a south or west-facing wall brings in strong sun and can overheat a room, so solar-control glass or integral blinds may help. North-facing bifolds benefit from high light-transmission low-E glass to make the most of winter daylight.
- Access and setting
- Long, heavy bifold panels need planned access through the house or a side passage, and parking close by for unloading. In terraces and flats, check permitted development rights, freeholder consent and conservation area rules before ordering.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Bifold Doors in Wandsworth: questions
Bifold or sliding doors: which should I choose?
Bifold doors suit you if you want almost the whole opening clear in summer, because the panels fold and stack to the side. Sliding doors suit you if you want the fewest frames and the widest view when closed, because large panels glide past each other. Many people decide by how often they will fully open the doors.
What guarantee comes with bifold doors?
Manufacturer guarantees apply to the frames, coating, hardware, rollers and sealed units, and the terms are confirmed in writing. Cover for running gear can depend on regular cleaning and adjustment, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered before going ahead.
How long does it take to fit bifold doors?
Fitting a typical set of bifold doors takes one to two days on site, depending on width, removal of old doors and making good around the opening. The doors are manufactured to the survey sizes first, and the lead time depends on the system and colour; it is confirmed in writing when you accept the quote.
Do bifold doors need building regulations approval?
Yes. Fully glazed replacement doors like these are controlled fittings, and in England an installer registered with a competent person scheme can self-certify them, or building control approves the work. A new or widened opening is structural work and needs building control approval for the lintel or steel. Wales, Scotland and Northern Ireland set their own requirements.
