Saunier Duval boilers
Saunier Duval comes up regularly as a search but not as a current UK purchase, and the distinction matters. The installed base is genuine and some of those boilers are still working. We service and repair them where parts allow, and are straight about the point at which replacement is the better spend rather than stringing out repairs.
Saunier Duval is a legacy brand. We service and repair the installed base and advise on replacement — we do not offer new Saunier Duval installations.
What we see on Saunier Duval boilers
- Ageing installed-base units still in daily service
- Repairs constrained by what parts remain obtainable
- Replacement conversations where nothing carries the same badge
These are the patterns we see across the installed base, not a diagnosis of your boiler. Faults are identified on site before anything is quoted.

Saunier Duval questions
- Are Saunier Duval boilers still supported?
- Not as a current UK range for new installation. Servicing is straightforward and many repairs are still possible, but parts availability is the limiting factor and it is worth checking before spending on an older unit.
- Do you repair and service Saunier Duval boilers?
- Yes. Gas work is carried out by Gas Safe registered engineers, which is the legal requirement for working on any gas boiler regardless of make.
