We are a high usage household. Ours is between £130 - £170 a month for gas and elec combined depending on time of year. Kids with tech. We have a TV in each bedroom. TV in the lounge and kitchen. 3 x PC setups with multiple monitors and games consoles. Also have and use a tumble dryer often twice daily.
I do my best to combat it. I try to have the water and heating come on as little as possible but it's hard over the last year as with constant occupied house, people get cold and also the routine is out the window so we invariably find the water needs to be on a lot to account for random shower demands.
I use smart plugs for the kitchen hot tap to turn it off at night to save energy. Have one on the electric oil heater for the shed, plus on a couple of older TVs which tend to get left on at night and hence switch off at 1am. Also used them for xmas lights and stuff.
I do generally try to buy efficient appliances and electronics where possible and we don't have any incandescent bulbs in the entire house. In fact, we barely have even the CFL tube type bulbs now either. I think almost everything is LED aside from a couple of cooker hood and internal oven lights. I educate my household to turn things the **** off constantly!
I set the freezer to minus 18 rather than any colder. The fridge is on medium setting and still gets down to 5 degrees. My server is spec'd for efficiency in mind where possible and I do calculate carefully the trade offs in usage vs services and also now mining puts a spin on things.
The tumble dryer I might start measuring actually as I know it will be a killer. It's just so convenient though as hanging out washing to dry in the UK is obviously harder in the non spring/summer months. I don't chase standby items much as having measured things like TV's in standby, it tends to be often under a single watt. They do all add up, but you really are better off going after the big boys:
Tumble dryer
Immersion (rarely used these days by most)
Heating and water obviously
Electric Oil heaters or anything that attempts to heat an element
Kettle usage can add up
Basically all kitchen appliances
Hot tubs cost a bomb to run (hence I don't have one!)
Servers/PCs do add up depending. A lot of people buy "cheap" ex commercial rack servers and bung them in the loft as they are noisy beasts, without realizing they consume a few hundred watts just idling.
Another tip...try to eat together as a family more. My mrs often ends up cooking 4 different things for dinner to account for different tastes and meal times depending on schedules. Waste of energy.
. But your prices per unit don't look "too" bad"
