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.

Winter light and glass choice in Holyhead

Rules for sliding patio doors in Wales

In Wales, replacement external doors must meet 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

The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.

  • 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 from Holyhead

Yes, all door glass must be safety glass. Triple units in sliders are toughened or laminated.

How long does it take to get triple glazed sliding patio doors fitted in Holyhead?

After the survey, typical manufacture time is 5 to 8 weeks, and a door is usually fitted in a day.

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

In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
