- Multi-chambered uPVC profiles trap still air inside the frame, so the frame itself insulates well without needing a separate thermal break.
- As the least expensive sliding door material, uPVC lets you replace a draughty older patio door with modern double glazing on a modest budget.
- Woodgrain and colour foils, including anthracite grey and black, let a uPVC door match existing windows instead of appearing as a white frame on a coloured elevation.

Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Questions about uPVC sliding patio doors in West Sussex
Is the price different in West Sussex?
No. Guide prices for uPVC sliding patio doors are the same across mainland Britain, including West Sussex. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Do I need permission to replace a patio door with a uPVC slider?
In England, replacing a patio door on a house is usually permitted development if the new door looks similar, though flats, listed buildings and Article 4 areas may need consent. The work must be done by a competent person scheme installer or notified to Building Control, and the glass must be safety glazing. Wales, Scotland and Northern Ireland have their own planning and building rules.
How quickly can a uPVC patio door be fitted?
A uPVC sliding patio door is typically made in 2–4 weeks after you sign off the surveyed specification, the shortest lead time of the sliding door materials. A straight swap in the same opening typically takes 1 day, including removing the old door, fitting, sealing and making good inside. Times are typical rather than promised, and foiled colours can add a little time.
Should I choose uPVC or aluminium for a sliding door?
Choose uPVC if budget and a quick, simple replacement matter most, and aluminium if you want slimmer frames, bigger panels or a powder-coated colour. uPVC insulates well and costs less, but its frames are wider and its panels smaller. Aluminium suits openings over about 3.6 m and modern extensions. Our aluminium vs uPVC guide sets out the differences.
