Not in the UK, but Arizona in the US. A lot of low energy materials have linings that block signals significantly. They're meant to help insulate but a lot of the properties that do that also block signals. It's all EM radiation, just different wavelengths.
Modern Low-E windows linings meant to help insulate will block phone signals quite substantially compared to the past. Saw the changes happen firsthand over the last 20 years selling and repairing phones.
