Winter light and glass choice in Porthmadog

Rules for flats and apartments 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

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 from Porthmadog

Can windows in a flat be fitted from inside?

Often yes, which avoids scaffolding. It depends on the window design and access, checked on survey.

What about tall blocks?

Higher-risk buildings (18 m or 7 storeys and over in England) have extra building safety requirements. Talk to your building’s accountable person first.

How long does it take to get flat and apartment triple glazing fitted in Porthmadog?

After the survey, typical manufacture time is 4 to 7 weeks, and most homes are fitted in 1 to 4 days.
