Rules in Wales

In Wales, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.

Planning: 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.

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.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions

Is triple glazing enough for Passivhaus?

Triple glass is the starting point. The frame, spacers and installation all have to perform too.

What is EnerPHit?

The Passive House Institute’s standard for retrofitting existing buildings, with slightly relaxed targets compared with new Passivhaus builds.

Can you fit to my designer’s details?

Yes. We agree position, fixings and airtightness details with your designer before ordering.

Do you cover all of Mid Glamorgan?

We arrange surveys and fitting across Mid Glamorgan.

Do I need permission for Passivhaus and EnerPHit windows in Wales?

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