Triple glazing for period homes and conservation areas in Colwyn Bay
From the first measure to the handover pack, we handle period-style triple glazing for homes in Colwyn Bay and the rest of Clwyd.

Flush casements and sashes that councils tend to accept. In a conservation area, replacing windows on a house is often permitted development if the new windows look similar to the old ones, but councils can remove those rights with an Article 4 direction.
Winter light and glass choice in Colwyn Bay
On the shortest day, Colwyn Bay gets about 7 h 30 min of daylight and the midday sun reaches only about 13° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

Rules for period homes and conservation areas 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
