What to know about heat pump radiator upgrades in Bolton
Most homes can run on a heat pump if the system is designed properly, and Bolton is no different. The key is matching the heat pump and radiators to the home's heat loss.
In Bolton, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. For period homes in Bolton and across Greater Manchester, column radiators can keep the character of a room while giving enough heat at low temperatures.
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
- Extensions and loft conversions with large areas of glazing
- Rooms that already feel slow to heat, such as bay-windowed living rooms
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Supply and fitting of new radiators, valves and brackets
- Room-by-room heat loss figures for every heated room
- Balancing every radiator so each room heats evenly
- Pipework checks and any agreed pipe upgrades
Extensions and kitchen-diners around Bolton 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 Bolton quote.
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.

How long is the heating season in Bolton?
Bolton 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.
The steps for heat pump radiator upgrades in Bolton
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Bolton 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 Bolton: questions
What size heat pump does a Bolton 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 Bolton home.
Do I need new radiators for a heat pump in Bolton?
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 Bolton home gives a room-by-room list.
Do you cover Radcliffe as well as Bolton?
Yes. We arrange surveys and installation in Radcliffe, which is about 5 miles east of Bolton, and across Greater Manchester.
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.
