Why choose uPVC sliding patio doors in Reading?
Here is what to weigh up if you are considering uPVC sliding patio doors for a home in Reading:
For a rental or family home in Reading, frames that never need painting keep upkeep down to an occasional wipe, which is one reason uPVC sliding patio doors suit tighter budgets.
If the windows on your Reading home are white or woodgrain uPVC, uPVC sliding patio doors in a matching finish keep the rear of the house looking uniform.
- As the least expensive sliding door material, uPVC lets you replace a draughty older patio door with modern double glazing on a modest budget.
- Steel reinforcement inside the main profiles keeps the frame rigid, holds the locking hardware firmly and stops the sliding panel flexing over the years.
- uPVC frames never need painting or staining; an occasional wipe with warm soapy water keeps white or foiled finishes looking clean.
Sunlight, glass and orientation in Reading
Daylight in Reading runs from about 7 h 50 min in December to 16 h 38 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

How fitting works in Reading
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.
Rules for uPVC sliding patio doors in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Which options matter for uPVC sliding patio doors?
- Trims and cills. A matching uPVC cill, add-on trims and internal finishing so the new door sits neatly against existing plaster and brick.
- Foiled colours. Anthracite grey, black, cream or woodgrain foils on one or both faces, for an extra charge.
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
Questions about uPVC sliding patio doors in Reading
How soon can you survey in Reading?
Surveys in the RG1 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 2–4 weeks from survey sign-off.
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.
What sizes do uPVC sliding doors come in?
uPVC sliding doors are made to measure, so they come in any size within the system limits rather than set sizes. Our uPVC range covers overall widths from about 1.5 m to 3.6 m at standard 2.1 m height. Two panels cover most openings up to about 3 m, and beyond that a third panel is added. For larger openings, aluminium carries bigger panels.
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.
