Only had the boiler serviced a couple of weeks ago and everythign was fine then. However sicne then the weather has changed and temperature has dropped and Im suddenly noticing less than hot radiators and really slow running hot water. Any ideas as to why this may be, or should I just get somone in? Thanks.

I'm only guessing here but ................. wait's coming to me ............................

Is the boiler a white one, with pipes going to it, hanging on a wall?

Give the GasSafe guys a chance

Mftr & model would be a start
Is this a combi boiler, regular boiler, system boiler? As asked for a make /model would be a good start, system setup another.
