Hi Ant There are a few things that need to be taken into consideration:- Where you are in the UK as prices will differ from north to south Is there spare capacity within your current consumer unit to run a supply from it? Do you currently have RCD protection as the new circuit would require this. Perhaps you need to get a electrician to have a look and give you some advice Hard to give you a price.It prob wont be less than £150 but if other works are required you could pay £300-£400 Hope this helps If your in Lancashire you can always look me up on Facebook Russ
