I’m coming round to the idea of digging it out. Of course, if I’m doing that I will put in a decent amount of insulation. I may also be able to eek out another 10cm of head room which would be a bonus. I think the thing that confuses me is is the EPC lists solid floor insulation as the first thing to do, but it only raises the score by 1!! From 43 to 44. Which implies it is of limited value but of course I know this is not the case.

The ceiling height is only 2.33m so looking to minimise buildup. I had read if I understood correctly that 25mm xps would reduce heat loss by 50% so seemed worthwhile. That said I think I am going to do some investigation on the slab construction and depth of foundations. I can see the benefit in replacing the slab but if I have to underpin the walls it would be a non-starter due to cost I think!

Hi All Just purchased a 1970s detached dormer bungalow in north wales. Its a full renovation project. Heating is currently via a knackered oil fired rayburn. Solid floors and cavity walls. As part of the renovation works I would like to improve the insulation of the property and install a more energy efficient heating system. This is what I am currently thinking, - Walls - EPC says filled cavity, but will check this and top up if needed. Plus - internal wall insulation on all external walls (50 mm PIR bonded plasterboard drylining using GypLyner or similar) - Floors - 25 mm high density XPS glued to floor, engineered wood flooring on top (no battens). Have considered relaying floor but level of disruption is off putting - Roof - add 100 mm PIR board to dormer ceilings (there is no accessible loft as roof void is habitable space), minimum 300 mm loft insulation in eaves) - Heating - air source heat pump. New central heating system with oversized radiators, pipes run behind new drylining. - Windows and doors - replace all with A rated The EPC report for the property has it down as low E rated at the moment but is not much help as the only insulation recommendations are for the solid floor! This probably isn't going to be a forever house but likely will be there 10 years and we would like a nice warm property which doesn't cost a fortune to run. Am I thinking on the right lines?
