A friend is selling her house which she bought in 2002.The loft had been boarded out by the previous owners at some point and when marketed was described by the agents as a 'games room' as it could not be described as a fourth bedroom due to there being insufficient means of escape in the event of a fire perhaps.
My friend has received an offer but the potential buyer has stated that there is no building regs approval.On searching the gov.uk website there is no info.
I believe that some mortgage providers would be reluctant to lend if the necessary approval hasn't been given.When she purchased it nothing was shown on the valuation report or disclosed by her solicitor.
