Changing from back boiler to combi

I have briefly looked and costs were around £7k. My brother in law is having his done now and is moving a lot of pipes and was told by one plumber he would need all new pipework through out!

The guy doing has kept the existing rads, just moved gas and some pipework and removed hot water tank and expansion and cold water tank from loft. Think their bill is in the £8k region.
 
I paid no where near £8k,that sounds extortionate to me.

Best off getting a few quotes,preferably off people that come recommend.
 
Why not replace the old back boiler with a new one ? Baxi do a direct replacement for their old Bermuda line.
