worcester bosch combi 40kw in 4 bed house?

I have but been quoted £4.2k for the job which is a bit steep for me considering our gravity system currently works fine but is simply lacking a bit of pressure...

Tbh that's about right looking at about 1500-2000 for combi flue etc 500 for pipe and fittings and about 3-6 days work

You ever thought of just putting an electric shower in one of the bathrooms. Means you could still have a combi and if it ever went on the blink you still have somewhere to wash??
Just throwing in an alternative.
