Folding patio doors for homes and businesses in Newmarket
Creating a new bifold opening in an external wall is structural work that needs building regulations approval and a correctly sized lintel or steel beam. Replacing existing doors in the same opening is simpler. Planning permission may also be needed for new openings in listed buildings, flats or conservation areas.
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.
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.
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.
What a typical job includes
- Toughened or laminated safety glass to every panel
- Written guarantee terms and advice on building regulations sign-off
- Made-to-measure bifold doorset in your chosen colour
- Fitting, levelling, adjusting and sealing the frame

Newmarket at a glance
- Postcodes covered
- CB8 and the surrounding area, including Mildenhall, Haverhill and Ely
- Coast
- Newmarket is well inland, around 55 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Newmarket the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 61° and 16.5 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
- Rural gardens often slope or sit lower than the floor, so threshold height and drainage need careful planning. Exposed open sites benefit from stiffer aluminium systems, raised thresholds and outward-opening doors that seal against the wind.
- 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 Newmarket: questions
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.
Should bifold doors open inwards or outwards?
Outward-opening bifold doors are more common because the stacked panels sit outside and leave the room clear. Inward opening suits balconies, raised decks or tight patios where outward panels would block the space. The direction also affects weather performance and furniture layout, so it is decided at survey with the room plan in mind.
Are bifold doors secure?
Good bifold doors are secure when the traffic door has a multi-point lock and anti-snap cylinder, the other panels have shoot bolts top and bottom, the glass is internally beaded and the hinges and track resist lifting. Ask whether the system has been tested to PAS 24, and consider laminated glass for ground-floor doors.
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.
