• Are there businesses at the residential end of the scale that can do a detailed energy survey (more than just someone who tells you to get energy saving lightbulbs) and advise different solutions with different costs and savings, etc? Ideally someone independent rather than someone who wants to flog their solution.

    I had my central heating on for 5 hours, full blast, last night and that increased the temperature in the house by about 3.5 degrees (up to 17.5) and by the morning had dropped back down to about 12. Ideally I'd like to know whether this is due to poor insulation, poor heating, dodgy windows, etc. and how to rectify.

  • Bloody heck.

    A £50-100 EPC will give you exactly what you’re asking for. It will be very vague but you can use it as a starting point for getting detailed quotes.

    You can have a look at your neighbours to see if they already have one for a guide:

    But keep in mind older EPCs aren’t as good. They have improved info now, maybe since 2 or 3 years ago so find a recent one.

  • I can pretty much tell you what it will say;
    Insulate your roof space to at least 300mm;
    Fit double glazed windows (if you already have them replace the seals on the opening windows).
    Replace your bulbs with LED.
    Fit cavity wall insulation.
    Fit temp controlled rad valves.
    It’ll also say fit under floor insulation (as if!)
    Look at some EPCs online and just work though them on your place.
    Do the easy stuff before you get your own one done.

    The below was just pulled off the net.

  • Cheers, I have an EPC from when we bought the place a couple of years ago (it's on that site as valid until July 23), that's the pretty generic one which talks about lightbulbs.

    I want something which is more: this is where heat is escaping and this is how you could fix it or this room isn't heating properly because radiators are the wrong size, etc.

    I assume being end of terrace with a big west facing wall is one of the major issues. Not sure how that can be fixed for a reasonable cost or who I would ask about it.
