I live in a solid brick semi-detached house..The side of the house is currently pebble-dashed and in a poor state of repair, so we were thinking of getting it rendered and painted. This is potentially an opportunity to get exterior insulation. I know it would be expensive but I'd like to get a quote. Trouble is, I'm struggling to find firms that do this in SW London. I put my postcode into a Government website which claimed to list accredited installers, but it only returned one result - in Scotland - and they said they don't cover London. Am I just 5 years too soon? I've seen there are firms which do it for council flats, but I'm starting to wonder if its considered too expensive and difficult for the private domestic market. Yet energy-saving advice websites still seem happy to recommend it.
