Passivhaus and EnerPHit windows in Wrexham
We arrange surveys and fitting of Passivhaus and EnerPHit windows in Wrexham and the LL13 area, with a written, fixed quote after a free survey.

The windows and installation detail low-energy builds depend on. Passivhaus is a building standard from the Passive House Institute; EnerPHit is its version for retrofits.
Winter light and glass choice in Wrexham
Winter days in Wrexham are short: about 7 h 33 min of daylight on 21 December, with the sun peaking near 14°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for Passivhaus and EnerPHit in Wales
The rules for replacement windows in Wales are set by Approved Document L for Wales (2022 edition, with 2024 amendments): 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
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.
- 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
