Power to Shed. Requiring 32Amp supply

Engage a registered electrician, who will do some cable size calculations, armoured cable of the size calculated, buried or cleated from the main consumer unit to a sub board in your shed. This has to be RCD protected, when completed an Electrical Installation Certificate and notification to Building Control. You will receive a compliance certificate from BC. Edit...don’t take it as gospel for the size of cable-leave it to the electrician. After all we design & test etc. You have to understand that none of us have actually seen the job. But if others want to speculate and give you cable sizes etc etc, that’s up to them to give and you to accept. In your position I would get several quotes from registered electricians. Don’t please attempt to DIY this and by-pass the process. That’s why I never speculate on cable sizes etc on here, as some people, not you personally, I hope, will just go down to the big orange shed, get all the stuff and do it themselves from information on here.

Would need to run conduit underground, so dig out a trench 700mm deep and bring cable up inside, at 32amps you'll need a panel board and circuit breaker in a watertight box, cupboard or suitable spot and from panel you'll be able to run a ring main then!

You would need a minium of a 6mm SWA armoured cable buried or cleated from the main consumer unit to a sub board in your shed. This has to be RCD protected from inside the house depending if your main Cu has Rcd protection you might need to upgrade or install a separate rcd for shed supply ,when electrical works is completed an Electrical Installation Certificate should be provided and Building Control will be notified

Hi Paul, I would recommend you have at least two registered electricians come and perform a site visit to quote, to advise, and answer any questions you have. Our job is to provide you with solutions based on your needs and ensuring your electrical installation complies with Building Control. A site visit is best in most circumstances for an electrician, as many different factors determine what to install and how. We would look at your current electrical system, and what you would like installed. Quotes always seem to go more smoothly if you have a clear idea of what you would like, along with technical details of any equipment you wish to have installed. You would have no problem clipping the cable along a fence so long as the cable is supported and the fence is stable.
