    Can anyone give me a second opinion on this.

    Our power supply comes from the garage which is below the house. The meter, main switch and a small fused distribution board for the lights and power supply in the garage are all in the garage. The power supply for the house goes up to the main distribution board for all the circuits in the house.

    The boss wants a new electric double oven and a ceramic hob to replace the gas cooker we have now.

    The route to lay new cable/s from the house distribution board to the new cooker and hob venue is quite tortuous and would mean a lot of work and destroying a lot of decoration etc.

    Our electrician says the best way to do it is to install a bigger distribution board in the garage using 16mm cable to connect it to the main switch then take two separate fused supplies from it using 10mm cables to supply the double oven and ceramic hob individually via isolator switches on the kitchen wall. This way the route is straightforward and no decoration will be spoilt.

    The ceramic hob requires a 30amp supply and the double oven requires a 22amp supply.

    We have a quote for the work but it is a bit scary (apparently the 10mm cable is being offered much cheaper than it should be as the electrician has a large stock of it)

    Does anyone have any ideas of a better method or is this the way to go.

    Many thanks for any advice.

    it sounds quite a reasonable plan

    10mm cable is more than big enough, but at least it means that if in future you decide to get an all-electric Range cooker with 6 rings and 3 ovens, it will be big enough. Having two cooker circuits in the kitchen is a good idea as it means you can change your mind about where to put a cooker (I have two, on opposite walls)

    your electrician probably pays about £2 per metre for 10mm T&E on the reel. Is it a very long run?

    John thanks for your reply, I would say it is about 30 feet in total, about 15 feet down to garage and 10 feet across and max 5 feet up the wall. The vertical bit is in a concrete duct and across under a suspended floor then chased up the wall.
