Air Source Heat Pump Installation in Ealing
The pattern across Acton and South Ealing is already visible: heat pumps landing first in the well-insulated stock and renovation projects, then spreading as radiators get upsized and fabric improves. Getting a designed quote now — even to file away — tells you exactly where your home stands.
How a heat pump heats your home
The machine outside is half the story; the system design is the other half. Heat pumps deliver water at lower temperatures than gas boilers, which suits underfloor heating perfectly and requires radiators sized for the lower flow — sometimes existing ones suffice, often key rooms need upsizing. A hot water cylinder (heat-pump compatible) handles domestic hot water. Get the heat-loss survey, emitter sizing and cylinder right and a Ealing home runs beautifully on one; skip the design and no brand of hardware rescues it.
Is your home suitable?
The suitability checklist: reasonable insulation (loft and, ideally, wall), space outside for the unit with clearance and a spot that respects neighbours, room for a hot water cylinder, and emitters that can be made to work at lower flow temperatures — meaning some radiator upsizing is common and underfloor heating is ideal. Planning permission is usually not required under permitted development, with rules on unit placement. None of these is exotic; the survey checks all of them and prices what's missing.
Installation, MCS and what you receive
A typical installation runs two to five days: outdoor unit positioned and mounted, cylinder installed, any radiator upgrades fitted, pipework and controls connected, then commissioning — where the system is balanced, flow temperatures set, and performance verified. MCS certification wraps the whole process: accredited design standards, the installation itself, and the certificate and handover pack you receive, which the grant, some insurers and future buyers will expect to see.
One thing worth knowing about air source heat pump installation in Ealing: the age profile of the local housing stock shapes what engineers find behind the cupboard door. 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. That matters because a system's history determines whether a job is a straightforward hour or something that needs the pipework conversation first.
Frequently asked questions
How long does installation take?
Two to five days for most homes: outdoor unit, cylinder, any radiator upgrades, controls and commissioning. You'll have the honest schedule with your quote, including any day the heating or hot water is offline during changeover.
What is the Boiler Upgrade Scheme?
A government grant in England and Wales toward heat pump installation, paid via your MCS-certified installer and deducted from your quote. Eligibility broadly requires replacing a fossil-fuel system in an eligible property. Amounts change over time, so we verify the current figure with every quote — see our scheme guide.
Will my radiators work with a heat pump?
Some will, some won't — heat pumps run cooler, so radiators need more surface area for the same output. The survey checks room by room; typically a handful of radiators get upsized rather than a wholesale swap. Underfloor heating, where present, is ideal as-is.
Do I need planning permission?
Usually not — most installations fall under permitted development, subject to rules about unit siting. Listed buildings and conservation areas have extra considerations. The survey flags anything relevant to your Ealing property before you commit.
