Sounds like the pump is packing in, no where for water to go so overheating then high limit stat knocking pilot out, u need to see if motor on pump is spinning easiest way remove disc in centre of pump and make sure it turning whilst u run boiler.

ok cheers i'lcall someone up tommoro. if it is the pump how long would it take to fix and does it cost much? british gas do a call out and repair for £170 i think if it takes under 2 hours. used them earlier in the year for a different fault.

It takes 30/40 mins in total to change a pump head, inc fault finding, draining, replacing pump head and refilling. Thats Prob not the worst deal in the world
