Thanks for the offer JP but all is sorted, glad yours is ok, we've had N-Power round about a million times over the past few weeks but it appears they select their contractors according to the criteria of being bullshitting, tardy, rude and unable to fix a boiler.
Numptys.

I'm loving being able to sit in the front room without having to wear an arctic parka.

May all your boilers continue to bless you with heat and bountiful hot water, especially yours Big J, minus 15 ain't funny.
