Is a uPVC sliding patio door a good fit for your home in Slough?
These are the points a surveyor will go through with you when you choose uPVC sliding patio doors for a home in Slough:
Where a patio door in Slough opens onto a conservatory or narrow side return, a sliding panel avoids the clash a hinged door can have with furniture or a gate.
Replacing a tired patio door in Slough? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
- 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.
- Steel reinforcement inside the main profiles keeps the frame rigid, holds the locking hardware firmly and stops the sliding panel flexing over the years.
- Multi-chambered uPVC profiles trap still air inside the frame, so the frame itself insulates well without needing a separate thermal break.
How much sun will a door in Slough get?
Because Slough sees long summer days (about 16 h 38 min) and short winter ones (about 7 h 49 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.
What should you budget for uPVC sliding patio doors in Slough?
These are guide prices for fitted doors at a standard height, including VAT. They run from an entry-level system to a premium one at the same size; the survey confirms which suits your opening.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 1.5 m | 2 panels | £1,695–£2,095 |
| 2.4 m | 2 panels | £2,195–£2,695 |
| 3.6 m | 3 panels | £2,895–£3,495 |

Survey, manufacture and fitting around Slough
We plan the job around your home in Slough: survey first, then a written quote, then manufacture (typically 2–4 weeks from survey sign-off). The fitting itself usually takes 1 day for a straight swap in an existing opening. If you are in Maidenhead or Gerrards Cross, the same process and prices apply.
Do you need approval in Slough?
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.
Choosing the specification
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- Glass. Toughened double glazing as standard, with laminated, obscure or solar-control units available.
Questions about uPVC sliding patio doors in Slough
Do you fit uPVC sliding patio doors in Slough?
Yes. We survey and fit uPVC sliding patio doors in Slough and across Berkshire, including nearby Maidenhead and Gerrards Cross. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
How much do uPVC sliding patio doors cost?
uPVC sliding patio doors start from a guide price of £1,695 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £2,195–£2,695, and a 3.6 m three-panel door is around £2,895. Coloured foils, glass upgrades and a low threshold move the figure up, and the final price is fixed in a written quote after survey.
Are uPVC sliding doors energy efficient?
uPVC sliding doors are energy efficient because the plastic frame conducts little heat, with whole-door U-values typically around 1.3–1.6 W/m²K double glazed, depending on profile and glass. In England, a replacement door in an existing home with more than 60% glazing must achieve 1.4 W/m²K or better, so the sealed unit is specified to meet it. Wales, Scotland and Northern Ireland set their own energy requirements.
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.
