Why new boilers still need annual servicing

Manufacturer warranties on new boilers almost always require proof of an annual service — skipping even one year can void the entire warranty, even if the boiler is only a year or two old. Servicing also confirms the installation is performing as it should and checks for any early faults.

Common misconceptions

AssumptionReality
“It is new, so it does not need servicing yet”Warranties typically require the first service within 12 months of installation.
“The installer’s check-up counts as a service”Installation checks and annual servicing are different — keep your service record separate and up to date.

What it costs to skip a service on a new boiler

If your warranty is voided due to a missed service, any future repair — even in year two or three — comes entirely out of your own pocket rather than being covered by the manufacturer.
