Would strongly advise against this place.
Called them to fix my boiler, told them the issue and part that needed replacing (I knew the issue but didn't have the means to fix it). They came out 5 mins before closing, didn't even take the cover off, just relit it and left.

They still charged me full call-out fee.
I queried the fee considering they hadn't even had a proper look at the thing, but they said it was their policy and that was that.

Ended up getting the part myself and getting someone else to fix the boiler.

Seriously, go elsewhere.
