New Boiler Installation in Ealing
Ealing's Edwardian avenues and 1930s semis — Northfields, Pitshanger, West Ealing — carry classic suburban heating and hot-water layouts, joined by major new apartment quarters around the Crossrail stations. Boiler choice follows that stock: high-demand family houses in Hanwell often justify a system boiler and cylinder, while Greenford's flats and terraces mostly suit a well-sized combi. Our combi-vs-system guide covers the trade-offs honestly.
Combi, system or heat-only — the honest steer
Combi boilers heat water on demand — no cylinder, no tank, ideal for homes with one bathroom and decent mains flow. System boilers feed an unvented cylinder: better for two-plus bathrooms running simultaneously, at the cost of cylinder space. Heat-only (conventional) boilers with tanks suit some older systems where wholesale conversion isn't worth it. The deciding facts are your bathroom count, mains flow rate and airing-cupboard real estate — not fashion.
What happens on installation day
Day one, the outgoing boiler comes off and the new one goes up: flue, condensate, gas and water connections made, the system flushed and dosed, filter and controls fitted. Commissioning is the part that separates professionals — combustion analysed, gas rate verified, the benchmark log completed and building control notified. You end the day with a working system, a registered warranty and paperwork that will matter when you sell the house.
Warranties, paperwork and aftercare
Manufacturer warranties on new boilers run 5–12 years depending on brand and installer accreditation — but they're conditional: annual servicing by a Gas Safe engineer, recorded. Your installer should register the warranty, notify building control (you'll receive the certificate), and complete the benchmark section. Keep all three documents with the house papers; missing paperwork is a genuine friction point in Ealing conveyancing.
Coverage for boiler installation & replacement runs right across Ealing — Hanwell, Greenford and Dormers Wells border included — plus the surrounding Greater London area. Jobs route by proximity rather than by a call centre's guess at the map, which is why local engineers arrive with the right parts more often than not.
Frequently asked questions
How much is a new boiler in Ealing?
Most Ealing combi replacements land between £1,800 and £2,800 installed; conversions and system-boiler installs range higher, typically £2,500–£4,500. Your fixed quote follows a survey — the quote form on this page captures what the surveyor needs to price accurately.
What size boiler do I need?
Size follows demand, not house pride: bedroom and bathroom count, radiator count and mains flow rate determine it. Oversizing wastes money and cycles the boiler; undersizing disappoints at the shower. The quote survey calculates it — our sizing guide explains the logic.
Will you take away my old boiler?
Yes — removal and responsible disposal of the old appliance and any redundant tanks or cylinders is included in network quotes. Cylinder and tank removal in conversions is itemised so you can see its share of the price.
How long does a boiler installation take?
A like-for-like combi swap: usually one day. A conversion from cylinder system to combi, or a relocation: two to three days. You'll be told the expected duration with the quote, and the heating is commissioned and working before the installer leaves.
