Bifold doors are glazed panels that fold and stack to one side to open up a wide gap, while sliding doors glide past each other on tracks; both connect a living space to the garden and bring in more daylight.

Building in Fareham
Southampton and Portsmouth have dense Victorian terraces, with plenty of post-war rebuilding after wartime bombing. Winchester keeps Georgian and medieval streets, Basingstoke expanded rapidly with 1960s and 1970s estates, and New Forest villages feature cob, thatch and brick. Brick and flint is common on the chalk downs, and new estates ring most towns.
Terraces suit loft rooms and side-return extensions; post-war and expanded-town homes often need window, roofline and cladding renewal. Cottages in the Forest may call for lime repairs and planning-sensitive windows.
So when we survey a Fareham property for bifold or sliding doors, the first step is working out how it was built and what has been changed since.
Do you need permission in Fareham?
Homes in Fareham come under the regulations for England, summarised below. We don't rely on general rules alone: we confirm the position for your address with the council before a quote goes out.
Replacing windows and doors on a house is usually permitted development in England when the new ones look broadly similar to the old. Flats, listed buildings and homes covered by an Article 4 direction can need consent, and conservation areas may limit materials or styles.
Replacement windows and external doors must meet Building Regulations for energy efficiency, ventilation and, on upper floors, escape. The work is either self-certified by an installer registered with a competent person scheme or signed off by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

Frequently asked questions
How much do bifold doors cost?
Bifold doors cost £3,400–£9,000 for a typical 3m opening, supplied and fitted. As a rough guide, allow around £900–£2,000 per metre of width plus the fixed costs of fitting, depending on frame material and glass. uPVC sits at the lower end and slimline aluminium at the top. Widening the opening with a new steel adds to the price. We confirm a fixed figure after measuring.
Do I need planning permission in Fareham?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Fareham is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Can I have a level threshold?
A level threshold means the door track sits flush with the floor, so there is no step between inside and out. Most aluminium bifolds and sliders can be fitted this way, but the outside paving must sit just below the track with a drainage channel to keep rain out. Rebated thresholds give stronger weather protection with only a small step. We check floor and patio levels before recommending either.
Can you fit bifold doors where I have a window now?
Bifold doors can usually replace a window by cutting the wall down to floor level and, if the opening is being widened, fitting a new lintel or steel beam. A structural engineer sizes the beam, and building control approval is needed. Radiators, pipes and cables under the window may need moving. We check all of this at the survey and include it in a single written quote.
