OP, a modern un-vented cylinder such as the unistor only needs the PTRV and PRV checked once a year. Can be done at same time as boiler service. Probably no more than a tenner extra.
The new 440 highflow is a very good boiler and if you have been happy with the performance of the old one then whats the problem?
Considering the cost of a new 440 and that this figure include vAT I think it is quite reasonable, but make sure it includes a proper powerflush and all system controls being brought up to current standards.

Stick to you're googling and theory t w a t. Op whats advice from installers like us out there in the real world doing a proper job, not a bookworm with letters after his name who spends all his time on google to post on here
thnaks for that. The price does include VAT but not the powerflush which will cost extra around £400- £500. I am not sure which controls will be installed - is it reasonable to expect new timer for that money? Last, please can you recommend a good timer.
