Heat pump radiators for Orpington homes
In Orpington, 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.
We plan radiator upgrades in Orpington so floorboards are lifted only where pipework genuinely needs changing. Radiator fitting in Orpington 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 that already feel slow to heat, such as bay-windowed living rooms
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Rooms with little wall space, where a fan-assisted radiator fits better
What's included
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Room-by-room heat loss figures for every heated room
- Balancing every radiator so each room heats evenly
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- A radiator schedule showing which radiators stay, which change and their outputs
In Orpington, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump.
Grants and rules for heat pumps in England
Homes in Orpington 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.
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 radiator upgrades in Orpington: questions
Where would the outdoor unit go on an Orpington 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 Orpington home.
Do you cover Chislehurst as well as Orpington?
Yes. We arrange surveys and installation in Chislehurst, which is about 3 miles north-west of Orpington, and across Greater London.
How soon can you survey a home in Orpington?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
