The statutory nominal voltage in the UK is 230 V(+10% / -6%). The actual voltage varies according to the load on the system, which varies throughout the day, but it must not vary beyond the percentages quoted.
The rate we use energy is called power, and it is measured in watts. Power over time clocks up to energy in kilowatt-hours (kWh). (It makes no sense to talk about kilowatts per hour.)
kWh units of energy are totaled up in the electricity bill. UK households use 3-4000 kWh of electricity each year on average. This represents a rate of electricity consumption of about 400 watts on average. On average, each person in the UK uses about 200 watts of electricity and as there are 8760 hours in each year this adds up to about 1800 kWh per year each.

According to this page: Working couples consume 4117kWh
Single people consume 3084kWh
Nuclear families consume 5480kWh
They use 240 Volt, 50Hz power. Their outlets have 3 slots (one vertical, two horizontal) arranged in an isosceles triangle instead of a round hole and two slots, and they are typically connected in ring main instead of a radial fashion.
Answer
The nominal (i.e. 'named') supply voltage in the UK is 230 V which is allowed to vary between -6% and +10%.

Ummm .. How does an electric ray use its electricity ?
Could be a lot if the amount of charge is low as in static electricity.
A TV will use all the volts you give it. The amount of power on the other hand varies greatly depending on type and vintage.
