Kitchen refits, bathrooms and alcove joinery, often in a flat rather than a whole house.
In the news
The rules and money around energy upgrades moved a long way in 2026. The short version, with the sources.
The government's Warm Homes Plan, published in January 2026, offers grants and low- and zero-interest loans for solar panels, batteries and heat pumps, with fully funded upgrades for low-income households.
The Future Homes Standard amends the Building Regulations from 24 March 2027, with a 12-month transition: new homes in England must generate renewable electricity on site — in most cases rooftop solar — and be built with low-carbon heating. It covers new homes, not extensions or refits, but it shows where the regulations are heading.
The Energy Saving Trust notes that installation costs less if scaffolding is already up for roof work. If you are planning a loft conversion or an extension, settle where panels, cables and a battery would go while the roof and the walls are open.
The houses here
Victorian terraces alongside a lot of post-war and newer flats. Plenty of houses already converted, which changes what is permitted and what is possible.
What you need permission for
Southwark's householder guidance is the one to read before you draw anything. Permitted development does not apply to flats or maisonettes at all, so any external change needs a full application. A large single-storey rear extension can go ahead under permitted development but needs Prior Approval, which means the council writes to your neighbours first. In a conservation area, or anywhere the council has an Article 4 direction, those permitted development rights are cut back again.
Rules vary street by street, and none of this is advice about your particular house — we check yours before we quote, and we handle the applications.
