Hi Martine, Can't really give a cost as this would depend on quite a few things. Has your existing consumer unit got spare ways? or will a new one have to be installed? How much cable will be required? If its a house carpets and floorboards will prob need lifting.Do you require the cable sinking in the wall or running surface in plastic trunking. Best thing to do is post the job on here,put a small budget on and a electrician local to you should get in touch and he can call round and you can discuss and he'll give you a more accurate price
