I just went through all of my readings see attached. And perhaps I have exaggerated the cost a little based on what Bulb are currently charging me (£675.00 per month). In coldest winter months my usage is going over 80Kwh per day, but averages down to 59Kwh per day. But with the prices going up by a third on April 1st I will still hit north of £6k per annum, so worth investigating all of the suggestions re insulation and day/night rates etc

The funny thing about that is when I spoke with Bulb and told them I was alarmed at the cost, they ran a calculator their end and said if they charged me the daytime only rate I’d be worse off. So I’m going to check that, as I agree that doesn’t make sense

Sorry those figures are cost in pounds not units of electric

Sorry my mistake I quoted the actual cost of daytime and nighttime units in pounds

Sorry as per my other reply. What I quoted was the actual cost in pounds over 41 days. I wrote them down after working it out but didn’t state what they were.

Yes that’s fine. It was a new digital meter installed during refurb. They upgraded the supply to cope with the demand of the new Electric boiler

Sorry I made a sill mistake. The numbers I quoted are in Pounds! Not the units. That’s my cost over 41 days.

No the majority of my electric is used during the day, as I do not have night storage heaters remember.

there are a few of them, but many do not have easy access sadly. So will be a case of opening them up and then having them repaired and plastered after.

Yes I have full access to the loft. But as below, and potential buyer would need to be informed of the heating cost issue

This was my thoughts yes. I can access from the inside by making holes in the dry lined walls, and the cavities can be access quite easily. This is the stuff I was thinking of. Ignore the price though, you can buy a lot cheaper elsewhere https://www.travisperkins.co.uk/insulation-accessories/dupre-minerals-vermiculite-insulation-liner-granules-bag-100l/p/755408?gclid=CjwKCAiAyPyQBhB6EiwAFUuaku3gxdyeEoO97zWQjEalbkmO9PgzsiFxWv7D88OK4hIAKkyb70hCyhoCXrsQAvD_BwE&gclsrc=aw.ds

In terms of numbers for the last 41 days I used 634 day units and 140 night units. My provider Bulb is about to raise prices to 33p and 22p I believe and 38p per day SC

Yes I cover the whole top floor. The flat is large which is both a blessing and a curse! The one across the way pictured is similar. My thoughts regarding insulation so far are I can access the big void areas, as pictured in my message above, so was thinking of getting these all insulated. I know they are not great as food smells come up inside them from the flats below. Plus the amount of cold you can feel when near them is telling. As for the main walls, which are all dry lined. I was thinking of getting the natural grain type insulation, which is completely safe and fire retardant etc. Then making holes in the dry lining around each room and filling them. Lastly, I have not been in the loft and surveyed properly yet, to see why the builder didnt take the insulation right to the ceiling edges, but am guessing access is blocked some how This work will cost quite a bit of course. Not sure how much, but given the £675 I am currently paying Bulb each month, I would hope that I can recoup the cost quite quickly I do own the leasehold of the flat, so insulating etc isnt an issue, but they will not allow anything bolted on the walls outside. I could sell and move, but I would not hide the massive heating issue from a potential buyer, so it would probably devalue the property to some degree From reading the responses so far, it looks like insulation as best I can and go from there?

The underfloor had a thin layer of insulation, and then the thick pads that the pipes clip in to. Its concrete floor. I cant hang anything on the outside walls as my lease does not allow it. Landlord very fussy:-( in this block we are all in the same boat really. The flat is very large. probably clos to 2000 sq ft or so. I have suspicions that the dry lined walls have little or no insulation. I may be answering my own questions based on the current feedback so far here. But the attached image shows a corner of my lounge and the areas of concern for insulation

HI Everyone, I have a large 3 bed 2nd floor flat which cannot have gas. I had it refurbished 3 years ago. I took the decision rightly or wrongly to install water piped underfloor heating with a 14.4Kw electric boiler. Sadly I did not project manage the job and the builders were not good at all. They never checked the floor levels before they installed the underfloor heating, and ended up cheating in two of the largest rooms by pouring latex over the top of the heating to get rid of the undulations in the floor. They have since gone bust:-( My issue is the heating is so expensive to run. I am facing an annual electric bill of £8000 or more now, and that is with the cheapest supplier I can find. So I am looking at all of my options to try and reduce the cost. I know I can improve the insulation in the apartment, as there are a lot of cavities around the walls, as being top floor I have vaulted ceilings in every room. Whilst the loft is fully insulated, the purchase of a thermal imaging camera as shown that there are big areas around the sides of most rooms which could not be as easily accessed, and were left by my lovely builders. But insulation aside, I need to try and find a more energy efficient way to heat my home as this is killing me I have considered a heat pump boiler, but I do not believe I would be allowed to install the outside unit here as being a block of flats, putting anything outside is a no go. I have spoken to a heat pump installer who has informed me that the unit cannot be installed in a loft, even if I created a well ventilated area, as it still will not be enough air circulation etc. The boiler I have is slimJim (see link below), I am wondering whether there are other more efficient electric boilers out there, or are they pretty much the same? I am really struggling to think of any other options tbh, and wondered whether any of you guys who are much more knowledgeable might be able to help. I might freeze next winter if not!!! https://www.electric-heatingcompany.co.uk/electric-boilers/slimjim-electic-boilers/?gclid=CjwKCAiAyPyQBhB6EiwAFUuakt2EDYDZtRTPhzZ3ym_crE4Lz4C9swJ_SAN-VDW_ae9Li3hxhRprCBoCorUQAvD_BwE
