What to know about heat pump radiator upgrades in Hammersmith
Homes around Hammersmith range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
In Hammersmith, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Many older houses in Hammersmith still have their original single-panel radiators, so the survey checks each one against the room it heats.
We size each radiator to your room-by-room heat loss so a heat pump can heat your home at a low, efficient flow temperature.
- Extensions and loft conversions with large areas of glazing
- Rooms with little wall space, where a fan-assisted radiator fits better
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- Supply and fitting of new radiators, valves and brackets
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
- Room-by-room heat loss figures for every heated room
- Balancing every radiator so each room heats evenly
We plan radiator upgrades in Hammersmith so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in England
Homes in Hammersmith can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

How long is the heating season in Hammersmith?
Hammersmith sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat pump radiator upgrades in Hammersmith: questions
Can you service a heat pump in Hammersmith that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hammersmith, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Hammersmith?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Hammersmith home states the expected time.
How long does a heat pump survey take in Hammersmith?
A home survey in Hammersmith usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
Can radiators be changed without draining the whole system?
Radiator changes normally mean draining the heating system, which is why they are usually done as part of the heat pump installation. The system is then refilled, flushed, treated with inhibitor and balanced. Doing the radiators at the same time avoids draining twice and means the new radiators are commissioned with the heat pump.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
