Estimate my elec bill?

jayuk022002

Hi

I am moving in a weeks time out of my parents home for the first time into a 2 bedroom bungalow which we are renting.

The bungalow has a brand new full wet elec boiler with a tank and normal radiators. It is also double glazed.

It has an electric oven, washing machine, microwave and fridge/freezer.

I will have a tv and games consoles etc and energy saving bulbs everywhere.

Both of us work during the day.

What do you think my monthly bill would be roughly as i have no idea?

Could be anything....What did the previous tenants pay?

The national average is 3,300kWh of electric and 16,500kWh of gas. If that's for an average 3 bed house then you could divide by 3 then multiply by 2 then if you convert the gas usage into electric by multiplying by 0.75 (due to gas boiler efficiency losses) then I'll have a wild guess that's about what you will use. So that's 10,500kWh of electricity multiplied by the average unit rate of 12p per unit (including standing charges) that makes £1,200 per year or £100 per month. But as I started with it could be anything.

How long is a piece of string?

They are far too many variables to base any assumption on your usage. ie size of property, insulation, efficiency of the boiler, your comfort .

On a cautionary note I would put by at least £25-30 per week for both utils not for each even then you could accrue some debt/credit depending on usage

Also monitor your usage each month, obviously heating will be high until come March/April

Thanks. Unfortunately the property used to have gas or oil heating and the elec boiler is brand new so no previous bills im afraid.

Thanks. I am going to get one of the wireless electricity meters for a guide

Why don't you just take weekly meter readings.
You can chart your consumption on something like http://www.imeasure.org.uk/

Be aware that heating with full rate electricity will be 4 times more expensive than using gas.

4 times now...and here I am thinking electric was cheap. Ebico is 4.788p/kWh for gas. 14.501p/kWh for Standard electric. Electric is 100% efficient. Gas boilers average out at about 75% efficient (when taking seasonal efficiency into account). They never reach the claimed 90% efficiency. Electric therefore costs 2.5 times that of gas. Using E7 rates then daytime electric heating is 2.8 times more expensive and using night rate storage heating it's exactly the same cost. Taking into account the maintenance costs of a gas central heating boiler then electric storage heating is cheaper than the total cost of ownership of a gas central system.

Even if you use the best rates on the market of 3.5p for the secondary units of gas and 10-12p for the secondary units for electric then it still isn't 4 times more expensive.

The boiler is one of these wet systems

Not sure on what KW version the property has though

I can guarantee that it won't be the 4kw but it may be the 6kw. It will probably be the 9kw or may be the 12kw. All you need to know now is the unit charge for the electricity then multiply 9 by that number and you have the cost per hour of running that boiler.

Thanks. I have asked what tariff the elec is on but i have no idea on how long it will be running for at all

So why has it been switched to all-electric? Oil or gas would be much cheaper.
If mains gas is available, using anything else is crazy.
