When it comes to quality, we accept nothing less than 100%. That’s why we’re so confident in the reliability of our products that we offer an extensive guarantee with every purchase.

To help the installed system perform at its best, please ensure that the Vaillant boiler and associated system is serviced either by Vaillant or another Gas Safe registered company within one year of installation. All service details will need to be recorded in the Benchmark logbook provided by your installer.
