20kwh per day for hot water sounds about right to me
Are you comparing your usage with what you hope to achieve or what you have used at a previous property?

Hi, sorry to hear of your power cost concerns! My thoughts on your info, for what they’re worth...

- re the vacant apartment - they might have chosen to run heating and ventilation on timers to avoid mould build up for example.

- re the hot water - I agree with James, the energy consumed is likely to be about right. Electric hot water is almost 100% efficient energy conversion and so it’s simple to calculate (approximately) how many kWhrs are needed. For example to raise the incoming water temp from 15C to 65C using 6kW heater element will heat about 200l in 2hrs, so 12kWhrs is used. Then factoring keeping it hot and some use during the day a 3rd chunk of 6kWhrs seems a reasonable minimum. As that’s roughly the energy use you are seeing, my opinion is it’s unlikely your hot water service is faulty.

Can I suggest you install electric shower and an electric instantaneous water heater? At least then you can have hot water for washing and showering without such high Kw usage. Also what if you got some storage heaters and insisted on eco 7 heating??? would that be possible?

Horse's for courses's if you are a young couple that are at work all day, you definitely do not want an overnight economy 7 tariff for storage heaters, the majority of the heat will be given out when you are at work all day, take yourself off the economy 7 tariff, it's anything but, for a young working family, however electric shower and instantaneous water heaters are a good idea only heat up what you use.

It is expensive I agree. Unfortunately, LL is a property management company; but the company handling the energy is a completely separate company that manages the apartment block. They decided to use e-on, which I'm aware are pretty expensive as-is. They've assured me they don't charge anything above the electricity tariff but am waiting for evidence of this. LL didn't inform me of the fact that we were on sub-meters before moving in (and therefore unable to choose our own tariff), so I'm trying to get a rent reduction to cover this.

13kWh I don't think would be entirely unreasonable if we were using the central heating, or if we had access to hot water whenever we wanted it.

Even using standard UK average; 13kWh x 0.145 = £56.55, for a household of 2 people, with limited hot water, no central heating, and being extremely vigilant with turning off lights+switches+appliances - isn't that a lot?

Yes - access to both; after extensive argument with the block manager they eventually gave us the code for the door to access our sub-meter, so I've been checking it daily to monitor our usage.
No that is not a lot at all £56 per month is considerably less than what we use at home

To the OP, is this your first residence and therefore the bills are not being compared to a previous property, I only ask as the usage does not sound excessive IMO.
