Heating Installation
Does this new heating system quote look high for Sheffield?
Asked by Isla Patelin Sheffield, England· 4/14/2026· 404 views
I'm in Sheffield, England and dealing with a 15-year-old new heating system in our semi-detached home. Over the past week, it has been coming in with wildly different replacement recommendations and we're now noticing our energy use jumped before the comfort issue became obvious.
One contractor quoted GBP 903 for repair, while another jumped straight to a GBP 10,971 replacement because of the age. The weather here has been dealing us older housing stock with mixed insulation, 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.

From a contractor side, I would not approve a major repair or replacement without test results that line up with the symptoms. 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 used the directory reviews to filter out firms that were vague about what they had actually tested. That saved us a lot of time. 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.

The recommendation should be tied to measurements, not just the age of the equipment. Age matters, but it is not a diagnosis on its own.
