Boiler prices in Ealing depend on the type of home as much as the postcode. A flat near Ealing Broadway, a villa in Acton and a semi in Greenford each need different boilers, and flue routes, cylinder choice and controls move the final figure. 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
Ealing is often called the Queen of the Suburbs, and the borough has plenty of Edwardian and Victorian houses to match, from the terraces and villas around Ealing Broadway and Acton to the garden-suburb streets of Brentham and Hanger Hill. Further west, Southall, Greenford and Northolt have a dense mix of 1930s semis, post-war estates and new flats.
With so many period houses split into flats or extended into lofts, boiler jobs vary a lot. When we price new boiler installed in Ealing we check the flue routes, the pipework and the hot water demand, so the fixed price covers a boiler that suits the property.
After you pick your boiler and date online, a Gas Safe registered engineer arrives to strip out the old boiler, fit and commission the new one and register the guarantee, with Building Control notified so the paperwork is done before they go.
Ealing mixes Edwardian terraces, garden-suburb estates and busy flats near the Elizabeth line. Here is what we see most.
Ealing water is very hard, which shortens the life of combi heat exchangers. We check your postcode and fit a scale reducer where hardness is above 200ppm.
Period houses often have original pipework and boilers in awkward spots. We assess the system before quoting and fit a compact condensing boiler.
Brentham and Hanger Hill have design controls that can affect flues. We choose a discreet route and flag any consent needed.
New and converted flats around Ealing Broadway and Southall often need compact combis and careful flue routing under lease rules.
Interwar semis often suit a straight combi swap. We check pressure first, then add a filter and controls upgrade.
Controlled parking and narrow roads can slow an install. We plan the day so the engineer can unload and work without delays.
Our Gas Safe engineers cover the whole borough, from Ealing and Acton to Southall, Greenford and Northolt. See all our service areas.

All W5 postcodes plus W3, W7, W13, UB1, UB2, UB5 and UB6, including Acton, Southall, Greenford, Hanwell and Northolt, and nearby areas such as Hounslow, Harrow and Brentford. As part of a nationwide network of Gas Safe engineers, we also cover the wider area.
Ealing tap water is very hard, normally above 200ppm. 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.
Boiler replacement is notifiable work under Building Regulations, which your Gas Safe registered engineer handles through Building Control, with a compliance certificate to follow. Planning permission is not normally needed for a like-for-like swap, but in Ealing’s conservation areas such as Brentham Garden Suburb or Hanger Hill, check with Ealing Council before putting a flue on a front wall.
Yes. Boiler finance in Ealing 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.
