Heating fault finding & diagnosis
Our £75+VAT per hour rate includes boiler breakdown diagnosis by experienced heating engineers. This fee ensures that you receive an expert assessment to identify the issue. If an issue can be resolved within the first hour without ordering parts, you will be back to hot showers and warm radiators with no further costs.
Boiler repair is a cost-effective option for minor issues that don’t impact the unit’s overall performance. However, if your boiler is over 10-15 years old, frequently breaking down, or significantly inefficient, investing in a new boiler replacement may be more economical and energy-efficient in the long run.
The breakdown diagnosis forms the basis for effective repairs or, if necessary, a recommendation for boiler replacement. If boiler or heating parts are required, we will order the parts the same day, with most parts available within 48 hours if not a stocked item.
