Before you book: heat pump radiator upgrades in Kettering
In Kettering, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
In Kettering, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. Radiator fitting in Kettering 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.
- 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
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Balancing every radiator so each room heats evenly
- Draining, refilling, cleaning and inhibitor treatment of the heating system
Extensions and kitchen-diners around Kettering with large glazed areas get their own radiator calculation.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Kettering quote.
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.
What to budget for heat pump radiator upgrades in Kettering
The ranges below are typical installed prices for homes in Northamptonshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Kettering can need quite different radiators and pipework.
| Work | Guide price |
|---|---|
| Replacement radiator, sized for a heat pump (each, fitted) | £250–£450 |
| Upgrade of about 10 radiators | £2,000–£5,000 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,500–£3,500 |
Installed, inc VAT. The survey lists which radiators need changing.
How long is the heating season in Kettering?
Kettering has about 7 hours 40 minutes of daylight at midwinter and 16 hours 49 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Heat pump radiator upgrades in Kettering: questions
How long does a heat pump survey take in Kettering?
A home survey in Kettering 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 Desborough as well as Kettering?
Yes. We arrange surveys and installation in Desborough, which is about 5 miles north-west of Kettering, and across Northamptonshire.
Can you service a heat pump in Kettering that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Kettering, whoever fitted them. Tell us the make and model when you book.
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.
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.
