Does this new heating system quote look high for Sheffield?
Asked by Isla Patelin Sheffield, England· 3/27/2026· 606 views
I'm in Sheffield, England and dealing with a 18-year-old new heating system in our small commercial unit. Over the last three days, it has been coming in with wildly different replacement recommendations and we're now noticing the technician who came out last time did not leave any actual readings behind.
One contractor quoted GBP 368 for repair, while another jumped straight to a GBP 14,921 replacement because of the age. The weather here has been dealing us damp shoulder-season weather, so I do not want to wait too long, but I also do not want to approve the wrong scope.
If you were comparing bids on this, what would you want checked first? I especially want to know how much weight you would give to load calculation, venting requirements, duct sizing, and equipment staging.

Before signing anything, I would ask the technician to show the readings and explain which number actually supports the recommendation. For a new heating system that is coming in with wildly different replacement recommendations, the first things I would ask for are load calculation, venting requirements, duct sizing, and equipment staging. If the contractor is recommending bigger work, ask them to explain which measurement supports that recommendation and whether they ruled out airflow or controls first. In Sheffield, England, pricing can move around, but the diagnostic process should still be clear.

If this landed on my schedule, I would want to document the core readings first and then explain exactly why the repair does or does not make economic sense.

The price range alone does not tell you enough. Ask what was tested, what failed, and which assumptions are built into the quote.

We had something similar and the turning point was asking each company for the actual readings in writing instead of a verbal explanation. We had a related issue with our new heating system in Sheffield. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

I would compare how clearly each contractor explains the diagnosis, not just the price. The clearer company ended up being the better hire for us.
