My electricity direct debit is £180 per month but that's largely because I use electricity to heat my home. If I recall correctly, Jennyjoan, you use oil for heating. £50 per month is equal to about £1.67 per day. At the moment nearly all electricity companies will be charging the maximum daily standing charge, which is 45p. If your supplier is doing so, that means that you're actually using about £1.22 per day for your electricity. [NB: That 45p daily figure is the maximum that can be charged in England, Scotland and Wales. It doesn't apply in Northern Ireland, so you might actually be paying quite a bit more]. That suggests that you might be using about four and a third kilowatt-hours of electricity each day at 28p per kWh. [However, because the Energy Price Cap doesn't apply in NI, your supplier could be charging a much higher rate per kWh, meaning that you're using less energy than my estimate].
Over 4 kWh daily use (without any heating) does seem to be rather high but
(a) it's better to overpay than to underpay, in order to avoid any nasty shocks at the end of the accounting period ; and
(b) because the Energy Price Cap doesn't apply in Northern Ireland, it's hard to do any calculations because you might be paying far more for your energy costs than the rest of the UK does.
