My first post in property & DIY! 
We have a loft conversion that was done about 15 years ago, long before we bought the house. We're replacing the flooring due to water damage and wondered about getting underfloor heating in the bedrooms up there to make it warmer- any thoughts please?
Our builder seems rather sceptical, says its expensive to fit and run. He's suggested bigger radiators instead, which we will also do.
Does underfloor heating work under laminate, and is it any good or a bit of a white elephant?
Thanks in advance
