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
Georgian and Victorian houses around the heath, a significant conservation area, and some of the best-known modernist housing in London on the Span estates — which have their own rules about what may be changed.
What you need permission for
Blackheath is split between Greenwich and Lewisham, with the heath itself as the boundary. The bigger point is the post-war housing: several of the Span estates around Blackheath Park are listed or sit in their own conservation area, and what may be changed there is defined unusually tightly, down to window frames and the colour of a front door. 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.
