Frequently asked questions
Is there a fixed national repair rate?
No. Regional providers set their own pricing. Request a quote for your site, equipment and urgency.
Are parts included in a service quote?
Check explicitly. Service kits, seals and remedial repairs may be separate, depending on the provider’s quotation.
Can a price be confirmed before diagnosis?
The attendance terms can be agreed, but the repair may need testing first. Ask for a separate repair quotation once the cause and compatible parts are known.
How is replacement priced?
A survey assesses output, quantity, access, gas/flue work, hydraulics and controls. The provider quotes the agreed installation and commissioning scope.
