Planning in Kensington & Chelsea
Do You Need Planning Permission for New Windows in Kensington & Chelsea?
Often not, if the building isn’t listed. The Royal Borough has a borough-wide Local Development Order for replacement windows in non-listed homes, provided the new windows look similar to the existing ones. Listed buildings still need listed building consent.
The council sets out the order on its check if you need permission page; the full conditions are in Part 3 of its planning register. Read them before you order, because a change in material, pattern or opening type may fall outside the order.
The council maps 37 conservation areas, and it can still remove permitted development rights with an Article 4 direction. The national permitted development rules for windows apply on top.
| Your home | What you usually need | Where to check |
|---|---|---|
| House, not listed, no Article 4 | No planning permission if the new windows look similar | Planning Portal guide for houses |
| Flat or maisonette | Planning permission | Your local council |
| House under an Article 4 direction | Planning permission | Article 4 map, then your council |
| Listed building | Listed building consent | National Heritage List for England |
If the house is listed, any change to the windows needs listed building consent. Check the address on Historic England’s National Heritage List for England. Applying is free, the council has 8 weeks to decide, and replacing windows without consent is a criminal offence. We supply profile drawings and material specifications for the application, and our page on replacing windows in listed buildings covers the rest.
Get the approval first, then order to the approved drawings. Ordering first and applying later is how people end up with windows the council won’t accept. Building regulations still apply to a full replacement; our standard double glazed windows have a whole-window U-value of 1.4 W/m²K, which meets Part L for replacement windows in England.

Glazing bars
Glazing Bars and Slim Double Glazing for Period Windows
On a Kensington or Chelsea facade, glazing bars decide whether a new window passes for the original. Solid through-bars, with each pane separately sealed, are the most authentic and cost £100–200 more per window than applied bars. Duplex bars are the most popular middle ground.
Slim double glazed units with solid Georgian bars come in at around 1.6–1.8 W/m²K, and we can make single glazed windows where a listed building requires them. A Georgian sash window on weights starts at £649+VAT.
Our page on Georgian style windows shows the bar types side by side. Send photos of your existing windows with your sizes and we’ll quote for the same pattern.
Timber and prices
Which Timber Suits a Kensington or Chelsea Home, and What Does It Cost?
Engineered pine starts at £449+VAT per window and lasts 25–35 years when maintained. Meranti costs about 20–30% more and lasts 35–45 years. Solid European oak costs £799–1,299+VAT and lasts around 50 years.
| Timber | Construction | Service life (maintained) | Price | Best for |
|---|---|---|---|---|
| Scandinavian pine | 3-layer engineered | 25–35 years | From £449+VAT | Painted windows on sheltered walls |
| Dark Red meranti | 3-layer engineered hardwood | 35–45 years | About 20–30% more than pine | Exposed walls |
| European oak | Solid | Around 50 years | £799–1,299+VAT | Grain on show, clear or stained |
For painted windows, engineered pine is the sensible choice. If you want natural timber, solid oak windows cost £799–1,299+VAT and last around 50 years when looked after.
Our timber sash windows on weights are balanced individually: each sash is weighed after glazing and the weights matched to it. On a main road, acoustic laminated glass adds £100–150 per window. Meranti and oak are compared on our hardwood windows page, and every upgrade price is under timber window prices.
