A sensor, valve or pump fault does not automatically justify a whole new boiler. The condition of the main exchanger, previous breakdowns and availability of suitable parts matter. A diagnosis provides a firmer basis than a general age threshold.

Compare costs over a realistic scope

Consider the repair quotation, likely related work and whether the appliance still suits the property. A replacement quote needs to include removal, connections, flue, condensate arrangements, controls and commissioning. Comparing only the price of the new appliance is misleading.

Reassess the needs of the property

Insulation, heat demand, occupants and simultaneous hot water use may have changed since the old boiler was fitted. A new system should be selected for current needs and technical constraints. Boiler and heat-pump options require their own feasibility assessment.

Plan rather than rush where possible

Discuss access, parts timing and the duration of the proposed works. Check current local requirements and any grant conditions separately; support should not be treated as guaranteed. See boiler replacement in Anderlecht to prepare your request.
