From Gloucester to Cirencester, we arrange triple glazed sliding patio doors for homes across Gloucestershire, with every quote fixed for the specification shown.

uPVC and aluminium sliders with low-threshold options. A sliding patio door has large glazed panels that slide past each other on a track, so it opens without swinging into the room.

Rules in England
England sets replacement door limits through Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules: a competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council, or a building control body approves it.
Before ordering: Replacing doors on a house is normally permitted development if the new ones look similar. Flats need planning permission for a change that alters their appearance, an Article 4 direction may mean permission is needed, and listed buildings need listed building consent.
How it works
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions
Are triple glazed sliding doors hard to open?
Not with correctly rated rollers. Lift-and-slide gear makes even very large panels easy to move.
Can I have a level threshold?
Low thresholds are available; they need a suitable drainage detail outside, which we check on survey.
How much does a triple glazed sliding door cost?
Our guide starts at £1,895 fitted for a 1.8 m uPVC slider and £3,295 for a 3 m aluminium slider, inc VAT. UK quotes for triple uPVC sliders run from about £1,600 to £2,600.
Do you cover all of Gloucestershire?

Do I need permission for triple glazed sliding patio doors in England?
In England, a replacement door on a house that looks similar is normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent.
