I’ve been informed by my letting agents that my property has been given an EPF rating of F.
What I don’t understand is why, it’s not that it’s poorly insulated.
My house has more than the industry standard loft insulation, it has cavity wall insulation and is fully double glazed throughout, plus a modern and up to date combi boiler and recent roof repairs.
Not that it makes any difference to insulation so far as I know but I also have UPVC soffits and guttering and renewed chimney.
Any help would be appreciated.
