Should I replace an oil boiler with gas in Glasgow?

That depends on whether a suitable gas supply is available and what changes would be required to the property. Moving from oil to gas is not simply a boiler swap: the fuel supply changes, the appliance and flue arrangements change, and the existing heating system still needs to be assessed for compatibility and condition.

If mains gas is available, compare the full conversion cost with the cost of replacing the oil boiler and retaining the existing fuel arrangement. Space, future servicing, fuel-storage arrangements and household preferences can all influence the decision.

Doherty works with both gas and oil boilers, which makes it possible to compare the two approaches for a Glasgow property without assuming one fuel is automatically the answer. A survey is needed before meaningful costs can be compared.
