Electric Heaters in new build home and lack of insulation

If you have solar panels, did you get a battery as well as part of the build?

That brochure is 100% green(wash). It's just a house built to current regulations, but with a poor heating system, as far as I can see.

I wonder if the mis-selling is egregious enough to be able to persuade the builders to pay for a heating upgrade? If everybody on the development is suffering, similarly, a "class action", with the threat of bad publicity, might be effective.

I'm not sure, but I know that all of the houses we asked are having the same issue. 
We changed the windows to winter mode hopefully this will make some difference.
We are also going to challenge them about the Dimplex's specifications as we believe the radiators they installed are not enough for this floor area.

Until you leave them on to warm up the fabric of the house you won't know what temp they can get rooms to and that means setting them to 20oC and seeing they can reach that as an example. 

So test that before challenging that assumption..

If you keep turning them off due to agile pricing as said before consider a change to tracker and then turn the heating on.

Just to echo @MultiFuelBurner comment above I'd be very surprised if you didn't save money by moving to Tracker and that is something you can do immediately and with no cost. Even if you keep your current heating pattern you'd probably save a bit, but the big advantage of Tracker is that you'd be able to use the heat at the best possible time for maximum effect without paying a premium for the electricity. Also, my house had low powered electric radiators when I moved in and they were fine if I never let the house get too cold but took forever and were ineffective if I let the temperature drop too far. And as you are finding they cost a fortune to run compared to other forms of heating. If you can find the money to pay for a better heating system (e.g. heat pump or night storage heaters) I expect that it would pay for itself in a few years as well as providing more comfort and adding to the value of the house. Good luck with whatever you decide to do, hope you manage to get something sorted.

yes we have 10kwh batteries (2x5)

You could use flux , and recharge the batteries between 0200-0500 @ 16.76 , but the daytime rate will be  27.93 and 1600-1900 @ 39.1 but then you would need to work how long your batteries will keep you going and if the discharge is sufficient that you don’t use too much grid power

Likely they will need 70kwh of use each winter day. 50kwh+ just on  their panel heaters and the rest hot water. So the batteries whilst useful I don't know if that ever beats a flat rate like tracker. Maybe maybe not.

Yeah I can’t get my head around those figures and I am working on a tablet at the mo so not easy to do what ifs. That is a lot of kWHs a day

I just blew my brains 100A fuse...there is black smoke the lot. 🤯

Are you calling it a Passivhaus (sp?) because the EPC is a A?

My bungalow is a B (91 points), but loses a lot of heat mainly through the slab of uninsulated concrete base it sits on, and the fact it's detached. 

How do you know the concrete base is not insulated? We have the beam and block base and from our research we understand it should be insulated, however we suspect there's no insulation at all as the floors are getting very cold and we know people from our site who had to have carpets even in the kitchen downstairs as they have 99.99% moisture in the floors which is constantly increasing instead of dropping. Also other houses have the same problems as us with the house not keeping the heat.

As someone kindly answered for me, it just wasn't done back in the 70s, and also because the floor is flipping cold. 

I wasn't saying your floor is uninsulated. I very much hope that modern buildings have higher insulation standards, but I have no clue what's mandated these days. 

I was just trying to show that a highish EPC rating doesn't necessarily mean that your heating needs will be negligible. 

Passivhaus is an entirely different thing, so was wondering if you'd assumed it met this criteria. 

Sounds like you may have, after skim reading the last few pages. Off to re-read them in more detail.

Arriving late to this thread but I am shocked at how the developer can make such a big play about sustainable and affordable living when they install peak rate electricity panel heaters as the only source of heating for the houses.
