As a part of our kitchen renovation we are having four additional double sockets installed - not because we anticipate increasing the number of appliances or load in any significant way, just to ensure that there will always be a spare outlet where it could be needed.
The first electrician to quote has said that we need an additional ring main because of the new sockets (he did not check to see how many existing sockets were on the existing ring main) and a new consumer unit.
As far as I am aware the limit on sockets is based on floor area (100sq m for the building?) and there is no other limit on the number of sockets although clearly common sense should prevail.
What concerns me more is the apparent need for a new consumer unit (and equipotential bonding?) - the existing is an elderly but visually sound metal 6 way Wylex fitted with mcb's with an added RCD for the ring main.
Grateful for any advice.
