Want to run some reasonably beefy tools in the garage- particularly an air gun and a welder.

Whats the biggest Ampgage plug that a sparks will install on a normal domestic single phase supply, and how much would it cost-"ish"to run a plug and 4m cable

What plug do these tools have?

If it is a standard 13A three prong then just run a separate ring main.

(I am assuming then when you say 4M, the garage is attached.)

garage atached, just need to drill a single whole through the wall direct to the distro board.

its more a case of buying kit to work in the garage- ie if i can get 32amp plugs then i can buy a proper welder!

Not that it's the answer but electric cookers run off a 30a circuit.

Sounds like that's a 3-phase unit?

And you'll need someone to fit sockets! Plugs are what you have on the end of the cable from the equipment which you want to plug in!

ETA
If it's one of these you need fitting (for 32A single-phase), you will need a dedicated fused spur which should be wired in using 6mm T&E.

You can run a 150A welder off a 13A socket with a normal 3 pin plug... I can weld 4mm plate without any issues with that... (ok more power would help, but with practice the weld is perfectly acceptable)...

Most compressors will run on a 13A feed as well....

Any bigger than 150A on a welder and you really do need a 32A spur from the consumer unit.

30A supply is what you need, my welder is 20A and has the 32A plug on it.

I had a spark wire an isolator up to a 30A supply, which we used to run a kiln from, I have now wired in some armoured trailing cable with machine socket on the end.

Buy a socket and some 6mm twin and earth. Run the wires around the garage from fusebox to socket leaving a generous loop of spare. Secure wiring to walls and call spark, he'll make good and you'll be rocking!

180A welder approx 5.2kW (23A ~ 230V), equivalent to a medium-large size electric oven.

That will require a 32A plug/socket to BSEN 60309-2 (as pictured above).

A 32A radial circuit from the consumer unit wired in 4 or 6mm².

Consideration should be given to the existing appliances & their diversity.

we don't have any big loads at the moment- heating and cooker is gas- shower is few from the hot water supply and is non-pumped. About the biggest load is the TV i would guess. We have an immersion heater but never use it.
