Triple glazing for period homes and conservation areas in Kent
From Maidstone to Swanley, we arrange period-style triple glazing for homes across Kent, with every quote fixed for the specification shown.
Warmth for period homes without losing their character. 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 England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Planning: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.
- 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
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 put triple glazing in a listed building?
Usually not as a replacement. Listed building consent is needed and is often refused for original windows. Secondary glazing is the common alternative.
Do you cover all of Kent?
We arrange surveys and fitting across Kent.
Do I need permission for period-style triple glazing in England?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent.
