Many streets in North and East London sit inside conservation areas. That does not mean you cannot replace your windows — but it does mean a little more care is needed before you order. Work through this checklist first.
1. Check whether your home is affected
Your council’s website has a map of conservation areas. Also check whether your home is listed, and whether your area has an “Article 4 direction”, which removes some of the usual permitted development rights for windows and doors on the front of a house.
2. Find out what the council expects
Most councils publish a short guide for each conservation area. Look for what it says about materials, glazing bars, opening styles and colours. Some accept well-designed uPVC that matches the originals; others prefer timber or timber-look frames on front elevations.
3. Match the originals
The details that matter most from the street are the proportions of the frames, the way the windows open (sash or casement), the size and position of glazing bars, and the colour. A good replacement copies these closely.
4. Get drawings and product details
If you need permission, the council will want to see what you are proposing. Ask your installer for drawings and product information you can include with your application.
5. Allow time
A planning decision usually takes around eight weeks. Order once you have the decision, so you are not paying for windows you cannot fit.
