Rules in Wales

Wales sets replacement door limits through Approved Document L for Wales (2022 edition, with 2024 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 as windows: a competent person scheme installer self-certifies the work, or building control approves it.

Before ordering: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material of a front door.

How it works

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • 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.

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.

Can I have a level threshold?

Low thresholds are available; they need a suitable drainage detail outside, which we check on survey.

Do you cover all of Dyfed?

We arrange surveys and fitting across Dyfed.

Do I need permission for triple glazed sliding patio doors in Wales?

In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
