Before you book: heat pump radiator upgrades in Shoreham-by-Sea
Every property in Shoreham-by-Sea is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
In Shoreham-by-Sea, bay-windowed front rooms are often the rooms that need a larger radiator when moving to a heat pump. We plan radiator upgrades in Shoreham-by-Sea 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.
- Extensions and loft conversions with large areas of glazing
- Rooms that already feel slow to heat, such as bay-windowed living rooms
- Homeowners who want the lowest practical flow temperature for efficiency
What's included
- Pipework checks and any agreed pipe upgrades
- Supply and fitting of new radiators, valves and brackets
- Making good around brackets and pipe routes, with any decorating agreed in your quote
- Draining, refilling, cleaning and inhibitor treatment of the heating system
- Balancing every radiator so each room heats evenly
Radiator fitting in Shoreham-by-Sea 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 Shoreham-by-Sea 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 Shoreham-by-Sea
The ranges below are typical installed prices for homes in West Sussex, including VAT. A survey sets the exact figure, because two similar-looking houses in Shoreham-by-Sea can need quite different radiators and pipework.
| 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 Shoreham-by-Sea's winters
On the shortest day Shoreham-by-Sea gets about 7 hours 56 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.

- We commission the heat pump, show you the controls and register the installation.
Heat pump radiator upgrades in Shoreham-by-Sea: questions
Do I need new radiators for a heat pump in Shoreham-by-Sea?
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 Shoreham-by-Sea home gives a room-by-room list.
How long does installation take in Shoreham-by-Sea?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Shoreham-by-Sea home states the expected time.
Do you cover Worthing as well as Shoreham-by-Sea?
Yes. We arrange surveys and installation in Worthing, which is about 5 miles west of Shoreham-by-Sea, and across West Sussex.
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.
