Rules in England

In England, 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: 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

You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

  • 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

Can I have a level threshold?

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

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.

Do sliding doors need safety glass?

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

Do you cover all of Merseyside?

We arrange surveys and fitting across Merseyside.

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.
