What to know about heat pump radiator upgrades in Bognor Regis
The question for a Bognor Regis home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Extensions and kitchen-diners around Bognor Regis with large glazed areas get their own radiator calculation. We plan radiator upgrades in Bognor Regis so floorboards are lifted only where pipework genuinely needs changing.
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
- Homes switching from a gas, oil or LPG boiler to a heat pump
- Extensions and loft conversions with large areas of glazing
What's included
- A radiator schedule showing which radiators stay, which change and their outputs
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Room-by-room heat loss figures for every heated room
- Supply and fitting of new radiators, valves and brackets
Radiator fitting in Bognor Regis is scheduled with your heat pump installation so the system is drained only once.
Grants and rules for heat pumps in England
Homes in Bognor Regis 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.
Heat pump radiators prices in Bognor Regis
These are guide prices for West Sussex, 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) | £260–£470 |
| Upgrade of about 10 radiators | £2,100–£5,200 |
| Pipework upgrade (e.g. microbore to larger bore) | £1,550–£3,650 |
Installed, inc VAT. The survey lists which radiators need changing.
Designing for Bognor Regis's winters
On the shortest day Bognor Regis gets about 7 hours 57 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump radiator upgrades in Bognor Regis: questions
How long does a heat pump survey take in Bognor Regis?
A home survey in Bognor Regis 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 Chichester as well as Bognor Regis?
Yes. We arrange surveys and installation in Chichester, which is about 6 miles north-west of Bognor Regis, and across West Sussex.
Where would the outdoor unit go on a Bognor Regis 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 Bognor Regis 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.
Will new radiators be much bigger than my old ones?
Sometimes, but not always. Swapping a single-panel radiator for a double or triple-panel model of the same height and width can raise output substantially, adding only depth from the wall. Where that is not enough, a longer or taller radiator, or a second radiator in the room, may be needed. We agree sizes and positions with you before anything is ordered.
