A common question from landlords in Swansea and South West Wales when I undertake an Energy Performance Certificate (EPC) is what’s needed to get to the forthcoming band C rating?
So I did an experiment, the current EPC was 67 points, a D band rating, so not much was needed – what’s the most cost effective way of getting to a band C?
Topping up the loft insulation to 200mm, that gave 70 points, a band C rating.
