Heat pump radiators for Grimsby homes
Most homes can run on a heat pump if the system is designed properly, and Grimsby is no different. The key is matching the heat pump and radiators to the home's heat loss.
Extensions and kitchen-diners around Grimsby with large glazed areas get their own radiator calculation. Radiator fitting in Grimsby 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
- 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
- Supply and fitting of new radiators, valves and brackets
- Balancing every radiator so each room heats evenly
- A radiator schedule showing which radiators stay, which change and their outputs
- Room-by-room heat loss figures for every heated room
- Draining, refilling, cleaning and inhibitor treatment of the heating system
We plan radiator upgrades in Grimsby so floorboards are lifted only where pipework genuinely needs changing.
Grants and rules for heat pumps in England
Homes in Grimsby 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 Grimsby
The ranges below are typical installed prices for homes in Lincolnshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Grimsby 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 Grimsby?
Grimsby sees roughly 7 hours 27 minutes of daylight in December and 17 hours 03 minutes in June. With a longer heating season than the south, the gains from low flow temperatures and good controls add up over the year.

- Tell us about your home: postcode, property type and current heating.
- We book a survey in Grimsby; 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 Grimsby: questions
Do you cover Cleethorpes as well as Grimsby?
Yes. We arrange surveys and installation in Cleethorpes, which is about 2 miles east of Grimsby, and across Lincolnshire.
Do I need new radiators for a heat pump in Grimsby?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Grimsby home gives a room-by-room list.
How long does a heat pump survey take in Grimsby?
A home survey in Grimsby 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 I need new radiators for a heat pump?
Not necessarily: many homes keep most of their radiators and replace only a few. The heat loss survey checks each room against its existing radiator at the planned flow temperature. Rooms with large windows, high ceilings or extensions are the usual candidates for an upgrade, while bedrooms often need no change. Your radiator schedule lists every decision.
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.
