Viewed a flat I like which was built in 2004. I'm a cash buyer. There's a car park on the ground floor with 4 stories above. It's brick with no cladding but I think some flats have small balconies. The day I viewed it, I read about the ESW1 certificates on here and now I'm worried that if I needed to sell the flat it would be very difficult and also that I could be liable for additional costs for the ESW1 certificate and the works required if recommendations are made. It seems that all flats have now been brought into scope and not just those over 18m or with cladding. I'm in such a quandary. Although I'm a cash buyer, I'm not well off and can't afford to make a huge mistake. All purchases carry some risk of course, but is it very risky to buy a flat now?
