Alright guys,

I have an L9 fault on the boiler mentioned above. The pressure had dropped but I have topped this up to just over 1 bar. I also bled the radiators to check their was no air in the system.

Any ideas what might cause this and how long it could be to do it. I was considering going with British Gas fixed price repair service...is this wise?

If you are DIY man no need ,pressure low of water must be leak in system look if pressure relief valve is ok, or may be radiator small leak in system
