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 and semis with later infill, and bigger gardens than nearer town. Two councils cover the area between them.
What you need permission for
Sydenham is divided between Lewisham and Bromley, which are two different planning authorities with two sets of local policy, so the same drawing can get a different answer on either side of a road. Parts of the area are conservation areas as well. Much of this area is covered by a conservation area, which removes permitted development rights that would apply elsewhere and brings windows, doors, roofs and front gardens into the application. Each conservation area has its own appraisal setting out the materials the council considers appropriate, and they differ — so the answer on one street is not the answer on the next.
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.
