Before you book: heat pump radiator upgrades in Nantwich
Most homes can run on a heat pump if the system is designed properly, and Nantwich is no different. The key is matching the heat pump and radiators to the home's heat loss.
We plan radiator upgrades in Nantwich so floorboards are lifted only where pipework genuinely needs changing. Many older houses in Nantwich 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
- Homeowners who want the lowest practical flow temperature for efficiency
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- 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
- Supply and fitting of new radiators, valves and brackets
Radiator fitting in Nantwich is scheduled with your heat pump installation so the system is drained only once.
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 Nantwich 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.
Heat pump radiators prices in Nantwich
These are guide prices for Cheshire, 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) | £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.
Winter daylight and heating in Nantwich
On the shortest day Nantwich gets about 7 hours 33 minutes of daylight, with the noon sun around 13° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.
How installation works in Nantwich
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Nantwich home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Heat pump radiator upgrades in Nantwich: questions
What size heat pump does a Nantwich 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 Nantwich home.
Do you cover Crewe as well as Nantwich?
Yes. We arrange surveys and installation in Crewe, which is about 4 miles north-east of Nantwich, and across Cheshire.
Where would the outdoor unit go on a Nantwich 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 Nantwich home.
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.
