Currently something like £1050/year for gas (It went up a lot when our fixed tariff came to an end). I don't have a way of separating space heating from hot water, but eyeballing the graph for the last year suggests it's something like a 4:1 ratio (assuming we use the same amount of hot water all year round, which isn't going to be true as we wash more in warm weather).
Some amount of resistive electric heating (I only have rolling averages) which varies at the whims of weather and illness (we used a fan heater extensively when barkata was stuck downstairs after her hip surgery, so recent figures would be atypical). I don't have a good figure for the boiler's electricity consumption, which seems significantly higher with this newer model, on account of it spending much more time pumping tepid water around in order to do load compensation.
Plus the room we spend most of our time in during the day is heated to the order of a few hundred watts by computers.
This is in an ISO standard Victorian terrace, with landlord-quality insulation. We keep things somewhere in the 19-22C range, depending on what we're doing, because we're not masochists and I value my lungs.
We rarely have visitors, but have people who do found that ventilating for covid reasons has lead to a significant increase in heating use? On the odd day we have had to have windows open for prolonged periods in winter, it's roughly doubled our gas consumption.
