    Is someone in a 1960's detached cavity wall house with 100mm fibreglass only in their loft and nothing in the cavities and an old gas boiler got any chance of reaching an EPC of "D" ?

    Hoping to get them to do improvements anyway but they want a D now.

    Roll some 200mm quilt over the top in the loft ( probably £30 from DIY shed)
    Stick some CFLs in all light fittings (£20 for 10 ?)
    fill the cavity with eps graphite ( just had a large 5 bed house done I'm working on for £250ish , (70mm cavities))

    Ha presto , cheap energy efficient refurb, drop the bills buy £300+ per year a least and make EPC C

    Shouldn't be too hard. My place had a D when I bought it:

    1947 semi
    Filled cavity wall
    Uninsulated suspended wooden floor
    70mm of nasty old rockwool in loft
    About a quarter of windows single glazed
    No low energy lighting
    Non-condensing boiler
    Chimneys open to the sky

    Getting a D on the gas network isn't hard at all if my place got one in that sorry state. I agree with James, insulate cavity and loft and whack some CFLs in, maybe some better heating controls if it doesn't have a programmer and TRVs. No need to throw lots of cash at it.

    This slightly noddy home energy check on the EST webpage - gives an EPC type output for a house.
