extractor fan keeps cutting out and stops the boiler from turning on

Efficiency is a ratio expressed as a percentage of heat out divided by heat in.

I imagine your boiler will be between 90% and 95% efficient.

Efficiency figures for many boilers here...

But unable to see your specific boiler in the lists.
