    The answer to the question is that the grades A, B and C relate to the quality (and thus the longevity) of the frames, not the glass, and whether you go for A or B makes only a minimal impact on the EPC in terms of improved energy efficiency. It's just more cost effective for the owner in the long run.

    Even if it did, do you think you'd be able to convince your EPC assessor of that, that you had the better windows, and that in view of that, your EPC grade should be higher?

    There's a lot of 'if's' there, all of which have to be fulfilled. More hassle than it's worth I think.

    EPC & grade of Double Glazing

    I've a 1/3rd of a house (to complete it) & a complete house to have double-glazed:

    Found suppliers (probably being fitted by my tame builder) - one of whom quotes "A" & "B" grade, B cheaper.

    Does the grade make any difference to any EPC assessment, please??

    Regards & thanks in advance..

    I’ve recently had an EPC done on a 1 bed flat that only has electric panel heaters. The flat was given and F23 with several recommendations, being external/internal insulation and high heat retention storage heaters with a dual immersion cylinder. Obviously I am so far off an E that just changing...

    I would keep the existing panel heaters and buy some ordinary 2nd hand storage heaters from ebay. These can be wired to spur box timeswitches if you don't have Economy 7 wiring. Only bother with lounge, hall & maybe bathroom if there's room in there. You don't need to put a storage heater in the...

    If you have a loft hatch, stick an extra 300mm insulation all around it - most assessors are too lazy to bring step ladders or climb up there so will do a basic visual check. My last one stood on a stool and held his camera by his fingertips to get an idea of the thickness.

    You would need to replace all three, as the assessor may spot one and make an assumption that they are all the same. I would discuss with assessor how many additional points it would add, just before you make the investment.

    Also the governments green scheme is due to be launched soon,...

    If it is caused by condensation - probable on an outside wall - you could try painting the wall with bathroom paint (anti mould). I have found this effective where condensation is causing mould behind wardrobes on outside walls. You would need to clean off the mould & treat the stain with a stain...

    Hi, I’m a farmer (in England) with two cottages that are currently rented out. We have spring water ( which I’m responsible for) and septic tanks for sewerage. I’ve never made any charges for water or sewerage ( despite spending ~40K on improving the water supply over the past few years).

    I doubt any official will want to take a close look either. Is there any reason they would want to investigate? Neighbour's is 60 years old and still as good as when it was built.

    ​​​​​​I don’t really fancy replacing it either, but I really wouldn’t want anyone official taking too hard a look at the existing septic tank. On the other hand, I’m confident that it isn’t causing pollution so probably all that any official could do is require its...
