Before you book: replacing an oil or LPG boiler with a heat pump in Royston
Every property in Royston 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.
If your home near Royston is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Owners across Hertfordshire can have oil tank removal arranged alongside a heat pump installation in Royston.
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
- Rural and village homes off the mains gas grid
- Older oil boilers nearing the end of their life
What's included
- Free survey with a detailed heat loss calculation for older construction
- Removal of the oil or LPG boiler and flue
- Help arranging LPG tank collection with your supplier
- Outdoor unit, heat pump cylinder, controls and radiator changes
- Network operator notification and electrical connection
Cottages and farmhouses in and around Royston often have solid walls, so the survey looks closely at construction and draughts.
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 Royston 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.

Short winter days in Royston and what they mean
On the shortest day Royston gets about 7 hours 44 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Replacing an oil or LPG boiler with a heat pump in Royston: questions
Where would the outdoor unit go on a Royston 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 Royston home.
What size heat pump does a Royston 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 Royston home.
How long does a heat pump survey take in Royston?
A home survey in Royston 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.
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.
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.
