Before you book: heat pump radiator upgrades in Putney
Every property in Putney is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
We plan radiator upgrades in Putney so floorboards are lifted only where pipework genuinely needs changing. Radiator fitting in Putney is scheduled with your heat pump installation so the system is drained only once.
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
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- Room-by-room heat loss figures for every heated room
- Balancing every radiator so each room heats evenly
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Pipework checks and any agreed pipe upgrades
Many older houses in Putney still have their original single-panel radiators, so the survey checks each one against the room it heats.
Grants and rules for heat pumps in England
Homes in Putney 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
What to budget for heat pump radiator upgrades in Putney
These are guide prices for Greater London, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £280–£500 |
| Upgrade of about 10 radiators | £2,250–£5,600 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,700–£3,900 |
Installed, inc VAT. The survey lists which radiators need changing.
Winter daylight and heating in Putney
On the shortest day Putney gets about 7 hours 50 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
From survey to switch-on in Putney
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Putney; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Putney: questions
How long does a heat pump survey take in Putney?
A home survey in Putney 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.
What size heat pump does a Putney home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Putney home.
Where would the outdoor unit go on a Putney house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Putney home.
Are fan-assisted radiators noisy?
Fan-assisted radiators make a low, steady fan sound when running at higher output, and many have quieter settings for bedrooms at night. They are useful where wall space is short, such as a kitchen with few clear walls. They need a small electrical supply, which we plan into the installation if you choose them.
How much does a heat pump radiator cost?
A replacement radiator sized for a heat pump has a guide price of £250–£450 each, installed and including VAT. Upgrading about ten radiators in a typical home has a guide price of £2,000–£5,000. The final price is fixed in your written quote after the survey, once the radiator schedule shows exactly which radiators change.
