Extra pipework and flue changes
Question to ask
Could extra pipework, flue extensions or condensate work be needed, and how will we agree the price before that work starts?
Why it matters
A boiler installation may need work beyond the appliance itself. Agreeing how extras are priced helps both sides understand what is being authorised.
What to confirm
The survey findings, proposed additional work, itemised price, any date change and written approval.
Clarify further if…
The answer is only “we’ll sort it when we get there”, with no agreement on evidence or approval.
