HUGE electricity bill!

Presuming the landlord isn't telling porkies, that would mean it was done before. So, if this was a new build, it would be the fault of the builder. In a new build, the builder decides what type of heating is required and registers the supply to get the meter fitted.

If you can dig back further, determine what type of meter hour heating needs, then if its a standard meter ensure their is no wired off peak load and ask your supplier to change it. Be onsite for this I case the engineer won't do the work because he would expect to be handed the sparkys contractors completion certificate but if you explained it, he should be OK. He just has to ensure his and your safety, if he can't, he will abort.

Then, since npower have acknowledged some blame, get your complaint handler to tell you how/many times they have had meter readers, meter engineers and so forth out there plus how np many times this rejected in their billing systems. This will give e you grounds to demand rebilling to standard as they haven't investigated what will appear as a faulty time switch which in this case would gave resulted in someone telling you what is on this thread. If they provided a settlement to the previous customer it makes it far worse because again they have ignored the situation, I think they should rebill you on standard rate elec charges, on the cheapest rate available when you moved in (providing you need the meter changing to a standard rate one).

Total mess but the supplier has made some errors, most likely due to it not being seen by someone with experience of metering investigation work!
