gas and electric use way above average

There is a small garden pond pump run 24/7
Three is a headless backup server running 24/7

If the pond pump is 100W and the server 200W, that's 2600kWh/yr right there.

2 under counter fridges
2 freezers in garage (1 chest / 1 under counter)

And that could be another 1000kWh/yr - 200 each for the fridges, 300 each for the freezers.

How many W has the garden pump?

I also need to replace a fridge freezer, only 2 years old, but something must have gone wrong, it is using almost 23 times what it should, over 2.2KWh per day instead of 320 KWh per year, that is almost 500Kwh wasted.

Let's start with the gas, quick and easy check, make sure your gas meter and your gas bill are using the same units...

If you have a metric gas meter (m3) but your billing assumes it is imperial (ft3) then it will be overstated by a factor of x2.83...

the meter has this written on it
Qmax 6 m3/h so I guess that is metric?

The bill lists
"Consumption 932.0 Units (m3 )"

So I guess it matches?

I would do a quick sanity test on the bill anyway, it has been known for them to mess it up even if the bill states the correct meter units.

Find a bill and divide the kWh charged by the meter units - should be around 11 for metric.

Immersion heater left on ?

Electric underfloor heating in bathroom etc ?

Electric showers ?

Your pond pump costs you £112 a year.

That 932 units should equal roughly 10,438kWh.

What period was that over?

Also you mentioned the thermostat at 21C, is that like that 24/7 or do you have it set for different temperatures through the day?

Also is there an uncontrolled radiator in the same space (not with a TRC on it)

10378kwh/932units=11.13

so ok?

immedsion off
no underfloor
hot water for showers comes from tank

Yes, it is correct, but as a guide, over that exact period we used 376m3 to heat a large 5 bed house, so you have some room for savings I'd say...

Key things we did for this last winter was to reduce the temperature setting on the boiler to around 55C (there is often a mark on the dial like an 'e' for eco...

Also fitted a simple programmable thermostat which allowed us to automatically change the temperature down to say 16C overnight, raise it to 19 for a couple of hours in the morning then down to 17C during the day when people are more active, then up to 20C for the evening.
