Gas and electrical safety

[vaguelyfamiliar]

So this weekend is going to be spent giving our newly acquired van a good clean all through, sterilising the water tanks and so on, however I'd quite like to have someone give all the internal electical and gas items the once over, can anyone recommend anywhere in the Herts / North London area?

Also going to be looking for a gas / carbon monoxide detector any recommendations?

Thanks
