Have just been quoted £5k (inc VAT) to have the following supplied and installed:

Worcester Bosch 40CDi combi boiler + vertical flue + 5yr guarantee
Full system flush & treat with corrosion inhibitor
Install 210-litre unvented hw cylinder
Additional expansion vessel
New safey valve
All necessary pipe work for above

For all of the work above is the cost reasonable?

Can't really say without seeing the installation, but doesn't sound too bad.
Sorry if infringed rule but have seen plenty of posts with advice on pricing with no moderator intervention
Again cant say without seeing. Why not get more quotes to compare to??

Hi sw,

The Worcester Bosch 40CDi isn't a combi boiler its a conventional boiler.

I agree with previous advice, get a few quotes and you'll soon know whether its good value.

To offer anything sensible here you will need to post more detail.

unless you live in a 20 bedroom mansion, you do not need a 40 kw boiler if it is indeed a conventional boiler. the only cdi models that i have seen are combis in which case you have no need for a cylinder, that would knock about a grand off the price.
Perhaps you are quoted for a combi boiler AND a cylinder because you have two bathrooms you want to use together.

Thats quite acceptable as long as you understand what you are getting quoted for.

Otherwise a lower power boiler, perhaps 15 or 18 kW?, would be adequate with a larger cylinder like a 310 litre. That would be the most economical solution.

Howver all the possible options should have been discussed with you by the CORGI rather than giving you a quote for just one option!

There is quite a lot of work and expertise in discussing the possibilities which is why we charge for visiting in cases like these!
