Triple glazing for period homes and conservation areas in Gwent
We survey and fit period-style triple glazing across Gwent, from Newport and Cwmbran to smaller towns such as Monmouth.

Heritage-style frames and plain advice on consents. 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.

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.
Before ordering: 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

Questions
Do you help with planning applications?
We provide drawings, specifications and samples you can use in an application. The application is made by you or your agent.
Will heritage-style frames look chunky with triple glass?
They can if the sections are too slim for a full triple unit. We will show you the frame sizes and, if needed, offer a slim high-performance unit instead.
Can I have triple glazing in a conservation area?
Often yes, if the new windows match the look of the old ones and there is no Article 4 direction. Check with your council first.
Do you cover all of Gwent?
We arrange surveys and fitting across Gwent.
Do I need permission for period-style triple glazing in Wales?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
