Hi all, I have a customer that has a grade 2 listed building being rented out to a charity. They are planning on selling the building but for obvious reasons are struggling. I recently completed a fire door survey which highlighted around 95% of the doors failing due to a mix of original panel doors and the fact it was left derelict for afew years. They are hesitant to complete any remedial works (which are rather substantial in cost due to the amount) and have been asking for other options. Is there an amount of time remedials need to be completed by or a percentage of remedials that needs to be completed? Any advice positive or negative would be greatly appreciated. Kind regards Simon Jeffries
