Before you book: heat pump radiator upgrades in New Milton
Most homes can run on a heat pump if the system is designed properly, and New Milton is no different. The key is matching the heat pump and radiators to the home's heat loss.
For period homes in New Milton and across Hampshire, column radiators can keep the character of a room while giving enough heat at low temperatures. We plan radiator upgrades in New Milton so floorboards are lifted only where pipework genuinely needs changing.
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.
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms with little wall space, where a fan-assisted radiator fits better
- Extensions and loft conversions with large areas of glazing
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
- Pipework checks and any agreed pipe upgrades
- A radiator schedule showing which radiators stay, which change and their outputs
- Supply and fitting of new radiators, valves and brackets
Many older houses in New Milton 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 New Milton 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.
Heat pump radiators prices in New Milton
Guide prices for New Milton and the rest of Hampshire are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £260–£460 |
| Upgrade of about 10 radiators | £2,050–£5,150 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,550–£3,600 |
Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in New Milton?
New Milton sees roughly 7 hours 57 minutes of daylight in late December against 16 hours 30 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.
What happens after you enquire in New Milton?
- Tell us about your home: postcode, property type and current heating.
- We book a survey in New Milton; 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 New Milton: questions
What size heat pump does a New Milton 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 New Milton home.
How long does a heat pump survey take in New Milton?
A home survey in New Milton 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.
Do you cover Lymington as well as New Milton?
Yes. We arrange surveys and installation in Lymington, which is about 5 miles east of New Milton, and across Hampshire.
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.
Can I keep my radiators and just run the heat pump hotter?
You can, but it usually costs more to run. Every extra degree of flow temperature reduces a heat pump's efficiency, so a system designed at 55°C uses noticeably more electricity than one at 45°C for the same heat. A few well-chosen radiator upgrades often let the whole house run cooler, which is the better long-term trade.
