Had a few issues with my Vaillant boiler which was doing overtime during the winter. Vaillant always send engineers promptly under warranty, no fuss, usually it's up an running again really fast. I'm super impressed, and special shout out to engineers 315 and 323, both really lovely, friendly and knowledgeable, great service all round!
