What to know about replacing an oil or LPG boiler with a heat pump in Gainsborough

Every property in Gainsborough 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.

Owners across Lincolnshire can have oil tank removal arranged alongside a heat pump installation in Gainsborough. For homes outside Gainsborough reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.

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.

  • Eligible homes in England and Wales within the higher grant window
  • Older oil boilers nearing the end of their life
  • Detached houses and bungalows with garden space for the unit

What's included

  • Help arranging LPG tank collection with your supplier
  • Outdoor unit, heat pump cylinder, controls and radiator changes
  • MCS certificate and grant application in England and Wales where eligible
  • Removal of the oil or LPG boiler and flue
  • Network operator notification and electrical connection

Bungalows and detached houses near Gainsborough running on LPG can move to a heat pump, with the tank collected by the supplier.

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 Gainsborough 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.

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

Where would the outdoor unit go on a Gainsborough 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 Gainsborough home.

How soon can you survey a home in Gainsborough?

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

How long does a heat pump survey take in Gainsborough?

A home survey in Gainsborough 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 I have to remove my oil tank?

Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.

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.
