Our work on conversions is managed by our team of specialist surveyors and inspectors. The team provides national consistency in interpretation of the NHBC Standards on variable and complex conversion schemes.

  • Cover for alternative accommodation and storage costs
  • Minimum claim value* instead of an excess
  • Cover against contaminated land

Please see the full Buildmark policy document below for all the conditions, limits and exclusions that apply.

* The minimum claim value explained: We don’t require policyholders to pay the first part of any claim. Instead, we operate a minimum claim value (MCV) which means that if the cost of a valid claim exceeds the MCV we will do the work or pay the cost in full and the policyholder will not have to make any contribution. The MCV for plots registered from 1 April 2018 is £1700 (increasing by £50 on 1 April in each subsequent year).
