Oil and LPG boiler replacement in Horley: what to expect
In Horley, 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.
Owners across Surrey can have oil tank removal arranged alongside a heat pump installation in Horley. If your home near Horley is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Older oil boilers nearing the end of their life
- Rural and village homes off the mains gas grid
- Owners tired of fuel deliveries and tank maintenance
What's included
- Free survey with a detailed heat loss calculation for older construction
- MCS certificate and grant application in England and Wales where eligible
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Help arranging LPG tank collection with your supplier
- Network operator notification and electrical connection
For homes outside Horley reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
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 Horley 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.
What to budget for replacing an oil or LPG boiler with a heat pump in Horley
The ranges below are typical installed prices for homes in Surrey, including VAT. A survey sets the exact figure, because two similar-looking houses in Horley can need quite different radiators and pipework.
| Home | Typical size | Installed guide price | After £9,000 grant |
|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £10,150–£13,400 | £1,150–£4,400 |
| 2–3 bedroom terrace or semi | 5–7 kW | £11,250–£14,450 | £2,250–£5,450 |
| 3 bedroom semi or small detached | 6–9 kW | £12,850–£16,600 | £3,850–£7,600 |
| 4 bedroom detached | 8–12 kW | £15,000–£19,250 | £6,000–£10,250 |
| 5+ bedroom or larger older house | 11–16 kW | £17,650–£24,100 | £8,650–£15,100 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.
Short winter days in Horley and what they mean
On the shortest day Horley gets about 7 hours 53 minutes of daylight, and the winter sun reaches only around 15° 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.

Replacing an oil or LPG boiler with a heat pump in Horley: questions
Can you service a heat pump in Horley that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Horley, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Horley 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 Horley home.
Where would the outdoor unit go on a Horley 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 Horley home.
What happens with a leased LPG tank?
Leased LPG tanks belong to the supplier, so the supplier arranges collection. Check your contract for notice periods and any charges before you fix a date. We time the switchover so you are not left without heating, and once the heat pump is commissioned the supplier can empty and remove the tank. Bottled LPG cylinders are simply returned.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
