Looking for Heating Survey recommendation for purchase

[RouxRussell]

We have had an offer accepted on a flat and I would like to get the heating checked. Unfortunately the gas supply was not on at the time of the building survey so was not checked then and both the heating and electrics were off during our viewings.

My partner would also like to get the electrics checked. I'm less keen on this as it is a ~ 600 sq ft flat, not very complicated and thought we could check ourselves ie. turn lights on off plug in a charger to sockets. But if the heating engineer could bundle this in that would be great. Are am I naive to think both can be done by the same professional or that our checks would suffice?!
