Ringing round for quotes for renewal motorhome insurance and I thought I would get a quote from NFU as a lot of people on here use them. All went well until they referred the installation of a replacement solar panel (30w to 100w) to the underwriters. They came back and said I needed to get an engineers report to the installation of the new panel, which is when I said thanks but no thanks. The only way to test the quality of the installation to my mind would be to try and prise the solar panel off the roof which would be self defeating.
