Founder & Owner:
Lee Nichols

Founded in 2005 by Lee Nichols, Assured Heating Essex has gained vast experience within the domestic and commercial heating sector. Day to day, Lee runs the office and attends all of the site surveys. With his determination and drive the company has gone from strength to strength, furthermore, is consistently growing. Lee is highly motivated, with exceptional multi-tasking and organisational skills…he is also the nicest guy you will ever meet!

At Assured Heating Essex we specialise in gas and oil heating systems that are energy-efficient, reliable and are value for money.

We are fully qualified to install and maintain any boiler type using quality heating supplies and we currently perform over 250 boilers installations per year in the local area.

We are accredited with Worcester Bosch, Viessmann boilers, Vaillant boilers, Glow-worm boilers and ATAG boilers. We are Gas Safe registered and are Oftec oil registered installers.

We have engineers that specialise in boiler installation, we also have engineers that specialise in system repairs. We believe different engineers have different strengths, an installation engineer is not necessarily going to know the common faults of a 15 year old boiler! We have a team of engineers that are experts in their own field.

We are proud of our reputation for meeting the needs of our customers while staying true to our principles of delivering the highest standards of customer service, based upon the core tenets of trustworthiness, professionalism, reliability and value for money. We have an office based in Rettendon, which is staffed Monday to Friday 9am until 5pm so feel free to pop down to see us!

Our customer commitment.

It’s not just about what we do; it’s about how we do it. According to Harvard Business School 80% of businesses claim to provide good customer service in contrast to only 8% of customers who feel the same way! We are committed to delivering the highest standard of professionalism and customer service, which is why we receive so many enquiries that start “you were recommended to us by my mother, father, sibling, colleague or friend”.

We understand the importance of the customer experience and welcome feedback. We are registered with and have over 750 feedback reports and an average customer satisfaction score of 10 out of 10. Please click here to read our latest reviews and to view our galleries.

Pride in workmanship.

No one likes a mess, so we will prepare the working area with dust sheets to ensure that your home remains as clean as it was when we arrived. Once that is sorted, we will pay meticulous attention to detail in installing/servicing your boiler, unvented cylinder, heating system, underfloor heating, solar heating, your heating controls, all so the system is working flawlessly.
