Bay window installation across London
Bay windows are one of the more involved jobs we do in London, and also one of the most rewarding for kerb appeal. The sheer size and borough-by-borough variation of the capital means what works on one street rarely applies two miles away, and bay windows are a big part of what gives those streets their character. Many boroughs have conservation areas or Article 4 directions covering entire streets, and a bay window is usually the most visible feature on the whole street elevation, so getting the style right matters.

Frequently asked questions
Why do bay windows cost more than a standard window in London? A bay involves three or more frames plus a roof or canopy over the top, and often some structural work to the wall below - all of which adds labour and materials compared with a single flat window.
Do I need planning permission for a new bay window in London? Usually not for a like-for-like replacement, but many boroughs have conservation areas or Article 4 directions covering entire streets, so it’s worth checking if you’re changing the shape or size of the existing bay.
How long does a bay window installation take? Most single bay window jobs in London take one to two days, depending on whether the roof over the bay also needs attention.
