Do you install heat pumps in Chatteris?

Yes. Chatteris is within our core service area, 12 miles from our Isleham base. We install Daikin Altherma 3, Vaillant aroTHERM Plus, Mitsubishi Ecodan, Samsung EHS, and Grant Aerona³ heat pumps for homes and businesses across Chatteris and the surrounding area. All installations are MCS certified and qualify for the £7,500 Boiler Upgrade Scheme grant.

How much does a heat pump cost in Chatteris?

A heat pump in Chatteris typically costs £7,000–£18,000 installed before the £7,500 government grant (Boiler Upgrade Scheme). After the grant, most Chatteris homeowners pay £0–£10,500 net — smaller 1-2 bed homes can be fully covered by the grant. The BUS grant budget was doubled to £295 million for 2025/26 and extended through at least 2028, with over 100,000 applications processed by mid-2025. We provide a detailed, no-obligation quote following a free home survey.

Is my Chatteris home suitable for a heat pump?

Most Chatteris properties built since the 1980s are suitable with little or no modification. Older properties may need some radiator upsizing or loft insulation top-up — we assess this at the free survey. Key factors are: wall and loft insulation, radiator sizing, hot water cylinder space, and external unit positioning. Modern heat pumps achieve seasonal COP of 2.8–4.5, with Octopus Energy's Cosy fleet averaging a real-world COP of 3.87. At SCOP 3.6, every £1 of electricity produces £3.60 of heat. EPC requirements for the BUS grant have been relaxed — alternatives to a valid EPC are now accepted.

How much can I save on heating bills with a heat pump in Chatteris?

On standard tariffs, a heat pump at SCOP 3.6 costs roughly £610–£720/year for a typical home — comparable to gas at £650–£750. On smart tariffs like Cosy Octopus (11.7p/kWh off-peak), heat pumps deliver savings of £250–£400/year over gas. Against oil boilers, savings reach 30–50%; against electric storage heaters, 60–70%. Pairing with underfloor heating (which runs at 30–40°C flow temperature) improves COP to 3.5–4.0, delivering 40–50% lower running costs than radiators with heat pumps. Solar panels can cut heat pump electricity costs by a further 40–60%.

Do I need planning permission for a heat pump in Chatteris?

In most cases, no. Air source heat pumps are permitted development in England, meaning no planning permission is needed. Restrictions apply in conservation areas (where the unit must not be visible from a highway) and listed buildings (which always require listed building consent). Chatteris has some conservation areas — we advise on this during the survey. Ground source heat pumps require planning permission but are less commonly installed in typical residential properties.

How long does heat pump installation take in Chatteris?

A standard air source heat pump installation in Chatteris takes 2–3 days. This includes fitting the external unit, connecting the internal pipework and controls, commissioning the system, and registering the MCS certificate. More complex installations involving cylinder replacement or radiator upgrades take 3–4 days. We typically schedule Chatteris surveys within 1–2 weeks and installations within 4–6 weeks of survey.

What is the £7,500 Boiler Upgrade Scheme and can I get it in Chatteris?

The Boiler Upgrade Scheme (BUS) is a government grant of £7,500 paid directly to the installer, which is deducted from your installation cost. You pay the net amount — you never handle the grant money. To qualify, your property must have an EPC with no outstanding loft or cavity wall insulation recommendations. We manage the BUS application on your behalf as part of the installation process. The scheme is currently funded to run through 2028.

Can a heat pump work with my existing radiators in Chatteris?

Many existing radiators work fine with a heat pump, particularly those fitted in the 2000s or later which are often oversized. Heat pumps run at lower flow temperatures (40–55°C) than boilers (60–80°C), so some older or undersized radiators may need upgrading. We carry out a full heat loss calculation and radiator sizing check during the survey. Where radiator upgrades are needed, we include them in the same installation visit to minimise disruption.

Heat Pumps in Chatteris

In Chatteris, heat pumps are increasingly popular as a like-for-like boiler replacement that qualifies for the £7,500 government grant. Running on electricity, a modern air source heat pump achieves a coefficient of performance (CoP) of 3.0–4.5, meaning every £1 of electricity produces £3–£4.50 of heat — compared to around £0.90 from a gas boiler.

How Heat Pump Installation Works

Free home survey and heat loss calculation

We visit your Chatteris property to measure room-by-room heat loss, assess insulation, check radiator sizes, and identify the right heat pump model and output. No charge, no obligation.

Detailed quote and BUS grant application

We provide a fixed-price quote showing the full cost, grant deduction, and net cost to you. We then apply for the BUS grant on your behalf before scheduling the installation.

Installation — typically 2–3 days

Our MCS-certified engineers fit the external unit, internal cylinder (if needed), controls, and connect to your existing pipework and radiators. Disruption is minimal — most Chatteris homeowners remain in the property throughout.

Commissioning and handover

We commission and test the system, set weather compensation curves for your property's heat loss profile, and walk you through the controls. Your MCS certificate is registered, activating all manufacturer warranties and grant compliance.
