With some very rough sums its looking like it would cost you £2 per hour to run everything; this at 14.5p per unit and using 14kW. This breaks down to 3 off 3kw heaters and 87 off 50W lights, plus the computers and white goods.

You would need to run this rate for 2000hrs to use £4,000 worth of electricity. There are about 2160 hours in a quarter so it would be just possible if you never turn anything off to burn this much electricity.

Can you take your own meter readings with the meter you have? If so I'd see how much you use in 24hours; bearing in mind you may have switched the heaters down as it is now almost summer.

Lectrician should be along later and he may be able to give you some more specific advice.

we did it for 1 week to get a good average use,

and yet they say that what we see has to be multiplied by 10 to configure the meter, also they will not help us by sending someone out to see what we have on to asses our situation properly

and thank you so much for coming back to me so quick, i do have a full list of items that we have here if that would help to approx give us an indication how much we should be charged as a small business

thnak you Pete

The digital reading on the meter usually has x10 at the end if it is required.  You will find this on larger services due to the high consumption.  They charge you per 10units, and not singularly.

You show some small export figures - turbine or solar?

Do you know your service size?  If you scroll through the menu items on the meter, what does it show you for CT ratio and VT ratio?

You could have around 5kw of lighting (58watt tubes), 6kw of heating (2kw heaters),  0.5kw of computers (125w each), circa 1kw of white goods.

That's 14.5kw, and lets assume 10 hours a day, and 14.5 per unit (R1/R2 average).

14.5kw x 14.5p x 10hrs = 2102.5p per day (circa £21)

£21 per day would be £7,665 per year, £1,916 per quarter.

What are you pence per unit rates?

You can hire check meters to install, we actually have one of our own these days as it seems to be a regular request by customers!

It is very rare to find metering errors, but I have seen the CT ratios set incorrectly for the installed CT's that have been installed.  This can cause large over or under readings.

What model meter is yours?  Ulster?  I would investigate the x10 issue and make sure it is correct - the meter should indicate this on it.

Where are you based?

I see Lectrician beat me to it & posted whilst I was composing my post!!

CCL is the "climate change levy" added on top of all units consumed.  Think of that as a tax.

What are the exact hours of occupancy?  Anyone on site between midnight and 7am?  What would be in use during these times?

When you say the water heaters are not used, are they on, but not being used, or off?

The heaters - how often are these on?

Give this spread sheet ago.

you can change the kW's, hours and unit prices.  Calculating cells are locked, although the password is just 'att'.

   

it is just a shop area, and the heaters are only in the offices, the shop has no heating.

Hours of work, everything goes on about 8am - 5pm mon-sat, 1 computer may stay on until say 7pm sometimes later if i am working.

for 4 nights from 5-8 there are some lights on for the dance room but that is only 9 max and a stereo.

the only thing left on over night is the fridges, and very very low watt lights for fire exits.

the waters heaters are there but we dont really use hot water, so guessing they will be on all the time

once again thank you so much for helping and only hope we can come to a positive conclusion.

nope nothing
