Never had any issues with radio reception in the UK, but I only listen to 'national' stations so may not lose the signals that much. If you're on local radio then the coverage on VHF is designed to be local as the transmitter power is very much lower - typically 2-3kW as against 50kW for a national station. VHF being 'line of site only', you will lose signal if anything gets in the line between you and the transmitter site.
