Electric supply to concrete garage?

[nondrip]

Can anyone help me please?

I want to install a couple power points and light in an unlined concrete garage. What do I need to do? What are current regulations? How do I install the points and light switch given that I cannot drill into the concrete? Is there anything else I should know? Sorry if this sounds daft but I will be getting an electrician in and don't want to be completely ignorant and/or ripped off!

Many thanks.

is the garage attached to the house or is it detached?

It's detached, Mr Winston - about 4 metres from the house. It has concrete walls, which have been bolted together, metal doors and surround and 2 wooden roof beams. It's a basic Comptons model.

I have a Comptons Garage.

The electric supply is carried on a catenary from the main supply in the house, and the cable enters through a small gap just under the roof, to a fused spur.
I have a fluorescent light, and a power point.

battens can usually be fixed to the concrete with metal ties, or wall plugs drilled into the thicker parts, depending on the design.
Overhead is cheap and cheerful - better would be buried steel wire armoured. Most important is an RD to protect the sockets at least, and posibly the whole lot. Sounds like a 16A radial would be fine for you.

There is timber on the door frame, which is suitable for mounting all the nccessary sockets etc, it is fairly simple to fix a wooden batten betweent the framework used for the roof structure on which to mount the fluorescent fitting, that is how mine is done.
I do have RD protection fitted, always best to be safe.
