Boiler prices in Havering depend on how the home has grown.

Like-for-like combi swaps start from £1,759 fitted, while Worcester Bosch Greenstar 4000 packages start from around £2,450. Every quote you get online is fixed – no surprise extras on the day.

Local boiler installers
Havering is London’s eastern edge and its greenest large borough, a mix of Romford’s busy centre, the Gidea Park garden suburb, Hornchurch’s tree-lined streets and Upminster’s older houses with fields beyond. Most homes are inter-war and post-war family houses, with flats near Romford and newer estates around Harold Wood and Rainham.
Plenty of Havering houses have been extended and loft-converted, so the original boiler is often too small for the way the home is now used. When we price boiler installation in Havering we check the size of the property and how many bathrooms it has before giving you a fixed price.
Choose your boiler and installation day online and a Gas Safe registered engineer arrives to remove the old unit, fit and commission the new one, register the warranty and notify Building Control, leaving the heating tested and signed off.
Havering is Greater London’s most easterly borough, with Arts and Crafts houses, garden suburbs and green-belt edges. Here is what we see most.
Havering water is very hard, shortening combi boiler life through scale. We check your postcode and fit a scale reducer where hardness is above 200ppm.
These homes have character and design controls. We plan a discreet flue route and keep original features intact while upgrading.
Extra bedrooms and bathrooms often outgrow the old boiler. We re-size the output to the whole house so winter heating keeps up.
Flats around Romford need compact combis and flue routes that meet building rules. We check both before quoting.
Older houses may have original pipework and awkward boiler spots. We survey carefully and propose a tidy, compliant installation.
A few edge-of-borough homes towards Havering-atte-Bower are off mains gas. We can also fit oil and LPG boilers on a fixed quote.
Our Gas Safe engineers cover the whole borough, from Romford and Hornchurch to Upminster, Harold Wood and Rainham. See all our service areas.

All RM1 postcodes plus RM2, RM3, RM5, RM11, RM12, RM13 and RM14, including Romford, Hornchurch, Upminster, Harold Wood and Rainham, and nearby areas such as Barking, Brentwood and Dagenham. As part of a nationwide network of Gas Safe engineers, we also cover the wider area.
Havering tap water is very hard, usually well above 200ppm. You can check your postcode on your supplier’s hardness checker. Where it exceeds 200ppm, we fit a scale reducer with a combi boiler, in line with Building Regulations guidance.
Yes. We remove the back boiler and associated fire, make the old flue and pipework safe, and install a modern condensing combi or system boiler in a more suitable position. This usually takes a little longer than a straight swap, and we’ll confirm the timescale before we start.
A boiler replacement is notifiable under Building Regulations, which your Gas Safe registered engineer handles with Building Control, so a compliance certificate follows. Planning permission is not normally needed for a like-for-like swap. In Gidea Park or Upminster conservation areas, check with Havering Council before moving a flue to a front wall.
Yes. Boiler finance in Havering includes interest-free, 9.9% APR and buy now, pay later options, with deposits from £0 – see our boiler finance page. All finance is subject to status.
Yes. Your engineer will safely disconnect, remove and dispose of your old boiler, and any redundant tanks or cylinder if you’re switching to a combi.
All boilers we install come with a manufacturer-backed warranty, typically between 5 and 10+ years depending on the model. Keeping it valid usually means an annual service – our boiler cover plans take care of that for you.
Yes. If your home is off the mains gas network, we can replace an oil or LPG boiler. Oil boilers are fitted by OFTEC registered engineers and LPG boilers by Gas Safe registered engineers with LPG competence. See our oil boiler installation and replacement and LPG boiler installation and replacement pages for more detail.
