Well we've bought our rear conversion today and now I need it fitted !!!

It comes with a Smev three burner hob and sink unit and a Indel B compressor chest fridge.
We don't have a leisure battery fitted at the moment and I want to run from the hook up point, does come with the consumer unit and what looks like a power inverter but I'm no electrician so can anyone recommend a local place to me near Newport gwent who can fit and connect up our kitchen.
The kitchen is a rear conversion that I bought through Ebay today.
Any help would be great .
