Most homes in Rettendon run on mains gas (58% according to the 2021 Census), so a like-for-like combi swap is the usual job, and next-day installation is available when the old boiler has failed. Water in the Chelmsford area is hard at around 260 ppm, so we talk through scale protection with every new boiler. We are about 10 minutes from Rettendon by van.
A boiler replacement is the biggest single job most households have done on their heating. We install new gas boilers across Essex, from a straight like-for-like combi swap to a full system change with a new cylinder, controls and pipework.
Next-day boiler installation. If your boiler has failed, we can survey and quote the same day and fit the new boiler the next working day in most cases, so you are not left without heating or hot water for a week while you wait for a quote. Tell us when you call and we will hold the slot.
Every installation starts with a survey at your home. We size the boiler to your radiators and hot water demand rather than to a brochure, check the gas supply and flue route, and give you a written quote. On the day, the old boiler comes out, the system is cleaned, the new boiler goes in with a system filter, and we commission it, register the warranty and show you the controls.
Essex Heating Engineers is a family firm with more than 40 years in the trade, Gas Safe registered (925538) and a Baxi Approved Installer. We also fit Worcester Bosch, Vaillant, Ideal and Glow-worm. Installation starts from £1,980 fitted, and manufacturer warranties are available, ask us for the term on the boiler you choose.

Questions about boiler installation and replacement in Rettendon
How much does a new boiler cost?
Gas boiler installation starts from £1,980 fitted. The final price depends on the boiler you choose, whether the flue or pipework needs moving, and whether you are changing from a system boiler to a combi. We survey first and quote in writing, so you know the full cost before we start.
How quickly can you fit a new boiler?
Next-day installation is available. If your old boiler has failed and you have no heating or hot water, tell us when you call: we survey and quote the same day where we can, and fit the new boiler the next working day in most cases, stock and access permitting. For a planned replacement we book the survey at a time that suits you and give you a firm installation date when we quote.
Which boiler brands do you install?
We are a Baxi Approved Installer and also fit Worcester Bosch, Vaillant, Ideal and Glow-worm. We recommend the model that suits your home, hot water demand and budget rather than pushing one brand. If you already have a boiler in mind, tell us and we will quote for it.
Should I choose a combi or a system boiler?
A combi heats water on demand and suits most homes with one bathroom, freeing up the airing cupboard. A system boiler with a cylinder suits larger homes where two showers may run at once. We look at your mains water pressure and how you use hot water before recommending either.
How far is Rettendon from you?
Rettendon is 8 miles from our base in Bowers Gifford, about 10 minutes by van. Same-day emergency cover and typical arrival in about 10 minutes.
