Ealing · W5 · Greater London
Fixed-price boiler quotes are online, and a Gas Safe registered engineer can be at your Ealing home or flat to fit yours – often as soon as the next day. Replacement gas boilers in Ealing cover combi swaps, system boilers, back boiler removals and complete heating upgrades.
Ealing has Edwardian villas, Acton terraces, garden-suburb homes and new flats near the Elizabeth line. Across W3, W5 and W13 we install Worcester Bosch, Vaillant, Ideal, Baxi and Viessmann boilers.
New-build flats near the stations often have tight cupboards and a set flue position, so a compact Baxi 830 or Vaillant ecoFIT pure is a natural fit. Edwardian villas usually need more hot water, so we often recommend a Worcester Bosch or Viessmann system boiler. In the Brentham Garden Suburb, we keep any external changes in line with the conservation area.
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. There’s no estimate to be revised later – the online quote is final. Anything you choose to add later is agreed with you first.
| Installation type | What’s involved | Price from | Time on site |
|---|---|---|---|
| Like-for-like combi swap | Replace an existing combi in the same position, with new flue, filter and controls | £1,759 | 1 day |

Ealing’s housing is some of the most varied in west London. These are the jobs we fit most and what usually works.
A system boiler and new cylinder often suit larger Edwardian houses, giving good pressure upstairs and down.
A compact combi keeps the footprint small. We check the flue, ventilation and your freeholder’s requirements first.
Straight swaps with modern controls give the biggest saving for the least disruption in these roomy interwar homes.
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. Hardness above 200ppm in your postcode means we fit a scale reducer with a combi.
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.

Often as soon as the next day, depending on the boiler you choose and engineer availability in the W5 area. Complete the online quote, choose when suits you, and homes without heating or hot water jump to the front of the queue.
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. Through a nationwide network of Gas Safe engineers, coverage extends beyond these places too.
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. Back boiler removal covers the boiler, the fire, and making the old flue and pipework safe. The new combi or system condensing boiler is then placed in the most suitable spot. It usually takes a little longer than a straight swap. We’ll agree the schedule with you up front.
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. We take care of the old boiler – disconnected, removed and disposed of – and any tanks or cylinder made redundant by 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 you’re off the gas network, we can replace an oil or LPG boiler too. An OFTEC registered engineer fits your oil boiler, while an LPG boiler is fitted by Gas Safe registered LPG-competent staff. See our oil boiler installation and replacement and LPG boiler installation and replacement pages for more detail.
