We have a loft conversion not to building regs we upgraded it nearly 5 years ago as there was a space there but not being used and in poor condition, following a re-roofing we had a visit from the council who saw the loft conversion and issued us with an unauthorised work file, we are trying to sort this out but are unsure if they had the right to issue us with the file after this time laps. They want to put new stairs in,smoke alarms and fire doors we are sailing close to the wind on costs as if it is worth doing because of the value of the property, we would like to sell at some stage but can't with this file issued or they want us to rip it all out !! already spent £9500 on the work 5 years ago. Any advise would be a great help
