Once complete, we’ll explain the condition of your system clearly and let you know if any further work is recommended.

I have used Assured since I moved in to the area a few years ago. I phoned needing an emergency repair, and within 3 hours of making the call, somebody had attended and the problem fixed. Transparent pricing, polite, tidy and faultless service from start to finish, I wouldn't go anywhere else!

Assured came and completed a powerflush of our heating system. The guy who came was both professional and curtious. He carried out the job efficiently and was very helpful when it came to explaining things. Would recommend this company.

I recently changed my boiler service package changed from HomeServe to Assured Heating Essex. Assured Heating attend my first annual boiler service under the package I have with them. All I can say is what a first class service I received from there engineer Mitch (who deserves a mention for his over all professionalism) I had my previous package with HomeServe for three years, but on my annual HomeServe boiler visit they never picked up a flue fault but Assured Heating did. The fault was, the flue was not sealed correctly on the outside of my property, the Assured Heating engineer Mitch explained the consequences of not having the flue sealed correctly. Mitch then proceeded to correct fault at NO ADDITIONAL COST. Great overall service from start to finish and I would highly recommend Assured Heating Essex..

In an age where people are quick to criticise but slow to compliment. A short note to thank Amy who oversees the professional team of Engineers at Assured Heating, Chelmsford. We have used this firm for over a decade for all our Gas & Plumbing needs. Their engineers are trained to the highest standards and consistently reliable on timekeeping, quality of work & fees. Please keep up the good work. We do not hesitate to recommend you where anyone asks for a recommendation.
