Trying to figure out if switching gas & electric is worthwhile

Do double check on your gas please -  give us the actual meter reads please (today and 12 months ago if you can) and look carefully for the letters m3 and cu ft  (whatever you do ignore any ref to kWh on your meter). 

These are the reading I'm using - 12 months as of 9 August 2020 & 2021 actual from my bills.
Electric 37069 - 27952 = 9117
Gas 10666 - 7955 = 2711

kwh for both as nothing showing as far as I'm aware in any other measure.

Gas usage in kwh is calculated on each bill - the figures you have are meter readings , hopefully in m3 - which equates to ~ 30,000 kwh !

What type of gas meter?  If its mechanical it will be cubic metres (or now rarely cubic feet).  I would be amazed if a house with gas heating and water can use fewer than about 250 cubic metres a year, which is an approximation what 2711 kWh would be.

We are considered low uers (8,000 kWh a year), gas use last month was 17 cubic metres just for hot water and cooking.

Nov to March the average was about 100 cubic metres a month.

You are clearly a high user. 9117 kWh electricity is about 3 times average. Gas meter readings are always in either cubic metres or hundreds of cubic feet. As has been said 2711 cubic metres equates to about 30,000 kWh. Also well above average. For heating and hot water in my 5 bedroom house I use about 13,000.

If you can, take a photo of the gas meter today, displaying the reading which you are using, and post it here, and folk here can advise. Likewise if you can photo or scan the most recent gas bill, redacting personal information, you will get further advice.

When this confusion is sorted out, there will be plenty of energy saving suggestions forthcoming.

@Brie - many modern meters can be very difficult to read.

Watch out for the decimal point and do not include any figures after the decimal point in the readings you give.

Be particularly careful if your meter has a small keypad.  You need to press 9 to get your reading which will be in m3. Do not attempt to convert this to kWh - that's what the computer will do.

The bill will charge for gas per kWh, but usually it first shows the difference in meter readings in m3 (or cu ft), and then multiplies that number by various figures to convert it to kWh. Do your bills show something like that?

@FeralHog

Nope just the kwh.  nothing about m3.

and what's a TRV?  the rads seem to have on/off spiggots, nothing fancier.  we don't really want to turn off all the rads - especially in the winter but we do have a timer on the boiler so they are only heating at certain times.  But that's all of them or none of them.

That's very odd.

Here is one of my bills.

You'll see it quotes my meter readings, calculates the difference to give a volume in m3, then multiplies that up to give a value in kWh that are charged.So eg. from 4th to 31st of Jan I used 162 m3, which converted to 1790.1 kWh.

Is there nothing like that on your bill?

Thermostatic radiator valve ... it's fitted to a radiator, has a dial to select target temperature, and will shut off the radiator when that temperature is reached.

Really you want a programmer/timer, a room 'stat & TRVs for efficient control - they will pay for themselves with fuel savings over the life of a boiler.
