What uPVC sliding patio doors offer homes in Farnham
These are the points a surveyor will go through with you when you choose uPVC sliding patio doors for a home in Farnham:
Planning a door wider than about 3.6 m for your Farnham home? That is beyond the uPVC range, so aluminium or a multi-track system would be the next step.
Replacing a tired patio door in Farnham? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
- 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.
- Shoot-bolt or hook locking on the sliding panel, plus anti-lift devices, help stop the panel being lifted or levered out of the frame from outside.
Daylight in Farnham and what it means for your glass
In Farnham the shortest day has roughly 7 h 52 min of daylight and the longest about 16 h 35 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
What should you budget for uPVC sliding patio doors in Farnham?
The table shows guide prices for common sizes, supplied and fitted, including VAT. Your exact price is fixed in a written quote once the opening in your Farnham home has been measured.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 2.1 m | 2 panels | £1,995–£2,495 |
| 2.4 m | 2 panels | £2,195–£2,695 |

How fitting works in Farnham
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 2–4 weeks from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a straight swap in an existing opening for a door like this.
Do you need approval in Farnham?
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.
Which options matter for uPVC sliding patio doors?
- Foiled colours. Anthracite grey, black, cream or woodgrain foils on one or both faces, for an extra charge.
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
Questions about uPVC sliding patio doors in Farnham
Do you fit uPVC sliding patio doors in Farnham?
Yes. We survey and fit uPVC sliding patio doors in Farnham and across Surrey, including nearby Aldershot and Fleet. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
Are uPVC sliding doors secure?
uPVC sliding doors are secure when the sliding panel has multi-point locking, anti-lift protection and steel reinforcement in the frame. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets. Laminated glass adds resistance to breaking through, and a key-locking handle stops the door being opened from inside if a pane is broken.
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.
