Oil and LPG boiler replacement in Romsey: what to expect

In Romsey, 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.

If your home near Romsey is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Rural properties near Romsey usually have garden space for the outdoor unit, sited away from windows and sheltered where possible.

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.

  • Owners tired of fuel deliveries and tank maintenance
  • Detached houses and bungalows with garden space for the unit
  • Eligible homes in England and Wales within the higher grant window

What's included

  • MCS certificate and grant application in England and Wales where eligible
  • Free survey with a detailed heat loss calculation for older construction
  • Outdoor unit, heat pump cylinder, controls and radiator changes
  • Help arranging LPG tank collection with your supplier
  • Removal of the oil or LPG boiler and flue

Owners across Hampshire can have oil tank removal arranged alongside a heat pump installation in Romsey.

Grants and rules for heat pumps in England

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 Romsey 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.

On the shortest day Romsey gets about 7 hours 55 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.

Replacing an oil or LPG boiler with a heat pump in Romsey: questions

Can you service a heat pump in Romsey that someone else installed?

Yes. We arrange servicing and repairs for most air source heat pumps in Romsey, whoever fitted them. Tell us the make and model when you book.

How soon can you survey a home in Romsey?

Survey dates depend on how busy installers are in Hampshire. We offer the next available dates when you enquire and confirm them in writing.

Do you cover Totton as well as Romsey?

Yes. We arrange surveys and installation in Totton, which is about 5 miles south of Romsey, and across Hampshire.

Can a heat pump cope with an exposed rural spot?

Yes. Air source heat pumps are designed to keep working well below freezing, and they periodically defrost, giving off a little vapour, which is normal. In exposed locations the installer chooses a sheltered position where possible, raises the unit to clear snow and let defrost water drain, and sizes the system for the local winter design temperature used in the heat loss calculation.

Is a heat pump cheaper to run than oil?

It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
