Getting new gas install signed off

[mellowyellow]

I'm just about finished building my interior.
My brother (who works for British Gas) is going to help me install the gas pipes and the electric wiring.
I want to know if there is a way of getting all the gas and electric checked out to make sure its all safe and legal????
I don't want to get to the summer and have the van blow up or the dog os the Mrs die of gas poisoning
If anyone knows of such a company who are local to me, i would be greatful for any help.
I live in Doncaster but work in Lincoln, so any companies close to either of these would be ace

maybe try a caravan sales place, some of them do servicing too. If not, ask Steve at Gasure, though not sure if he certifies anything that is not done by gasure

Thanks for that. Will try my local caravan shop.
I thought that i may have trouble getting it signed off if i did the gas and stuff myself.
Any idea how much it would cost to get the job done completly by one company???
