I should say it is. It’s well beyond the rating for a typical household

electrician help to set it up.

Your comment puzzles me.... standard UK outlets are 13A 240V, using a ring main rated at 30A total. 3kW is a standard "3 bar" electric heater.

Appliances that draw more than 1.5kW from memory.
Oh. No. They have changed it
On "modern" houses sockets are rated for 16A, being schuko type like maybe the entire EU.

You may be confused because I have mentioned in conversations that my entire (old) house is limited to 10A (actually 15 because design flaw of the meter-limiter), because it is an old installation that doesn't have a modern certification.
On a certified house you may easily have 10 KW, sometimes 15. More if you contract the three phases.
"All electrical equipment has an assigned electrical power (small or large) that is expressed in Watts (W) or kilowatts (kW). If we use several devices simultaneously, the electrical power of each adds up, until we reach a point where we can no longer use more equipment at a time so that this sum exceeds the electrical power we have contracted. This is the maximum power that can be consumed simultaneously.
When the maximum power is exceeded, the new digital meters disconnect the service and the home runs out of electricity supply. The most economical and efficient way to use electric energy is to have a low contracted power, as this will optimise the use of the equipment and reduce the fixed cost of the electricity bill."
