From my first conversation with Sian to installation of my new Vaillant boiler they have been absolutely brilliant. Sian responded instantly via What's App when ever I had a question regarding pricing and installation. Sam the installer and his colleague with very friendly, professional, tidy and talked me through the full installation once completed.

Service was professional and friendlyPosted on Google Olive Tree HouseTrustindex verifies that the original source of the review is Google. I’ve been dealing with ongoing pump issues for as long as I can remember, and after multiple visits from different plumbers, nothing ever fully got resolved. Harry from Jennings was the first to actually diagnose the problem and sort it in one visit. Professional, efficient, and clearly knows his craft inside out. I couldn’t recommend Jennings more highly.Posted on Google Stella OforiTrustindex verifies that the original source of the review is Google. Tristan was very polite, friendly and very professional. He is also very good at his job and very efficient. Very happy with the service
