Just thought I'd ask in case there are any gas fitters on here.
My boiler pilot light has gone out and won't stay lit.
It's an old boiler and it's had a few thermocouples I fit one maybe 15 yrs ago the last one was fitted by a gas engineer.
Gas safety has got a lot more strict since I fit one, would it be best to call a gas engineer or would I get badly done if I fit it myself?
