Now you've got at least one fairly comprehensive quote. Get some more and
eventually you will have the market price for somebody doing the job for

Bechmark it against BG and an independent. You may be able to find cheaper.
Only you can decide the value of going with a big name.

( I assume its you that has omitted the TRVs)
