Air Source Heat Pump Installation in St Ives

Heat Pumps in St Ives: A Conservation-Sensitive Heat Pump Market

St Ives is Cornwall's most internationally famous coastal town — home to the Tate St Ives and one of the largest conservation areas in Cornwall. With around 11,000 permanent residents and approximately 40% holiday-let occupancy, the heat pump market here is unusual: owner-occupier permanent homes and the substantial holiday-let economy both invest in heat pumps. CCS Heating & Renewables installs across TR26 from our Pool office, 10 miles away.

Where Heat Pumps Make the Strongest Case in St Ives

• Carbis Bay premium coastal properties: Larger plot sizes and easier outdoor unit positioning. South-facing aspects across St Ives Bay. 12–16kW Daikin Altherma or Mitsubishi Ecodan systems with 250–300L unvented cylinders. Net cost after the £7,500 BUS grant: £8,000–£14,000, or £6,500–£12,500 with the £9,000 off-gas uplift.
• Lelant family housing: Cavity-walled detached and semi-detached properties — straightforward retrofits. 8–12kW units typical.
• Halsetown & rural fringes: Off-grid detached properties, often oil-heated. Switching to a heat pump with the £7,500 BUS grant typically delivers a net upfront cost of £5,000–£9,000 plus £700–£1,500/year in fuel savings. See our oil to heat pump guide.
• Higher Stennack & Trewyn Estate modern housing: Already heat-pump-ready under Cornwall Council Climate Emergency DPD. Commissioning, MCS certification, and aftercare provided.
• Downalong & Upalong granite cottages: Substantial conservation area. Outdoor unit positioning requires careful planning. CCS handles listed building consent and conservation area consent applications.

The Conservation Area Challenge

St Ives has one of the largest conservation areas in Cornwall, covering the entire historic core. Outdoor unit positioning for heat pumps is tightly controlled — typically required to be in rear courtyards or non-visible side returns. CCS Heating & Renewables prepares the planning paperwork as part of the project. We have particular experience with the technical challenges of installing in the narrow lanes of Downalong and Upalong.

Holiday-Let Economy & Heat Pumps

St Ives has approximately 40% holiday-let occupancy across its housing stock. Heat pumps in holiday-lets reduce operating costs (versus oil or LPG), improve booking-platform sustainability ratings, and qualify for the BUS grant — £7,500, or £9,000 replacing oil or LPG with no mains gas connection — if the property is occupied for 50%+ as a residence. CCS works with several local holiday-let management companies on portfolio retrofits.

Costs After the BUS Grant

Typical net costs in St Ives after deducting the £7,500 Boiler Upgrade Scheme grant (£1,500 less again where the £9,000 off-gas oil/LPG uplift applies): £4,500–£6,500 for a Higher Stennack semi; £6,500–£9,000 for a Lelant detached; £8,000–£14,000 for a Carbis Bay premium coastal property; £5,000–£9,000 for a Halsetown rural detached.

Pair with Solar & Battery

Combining a heat pump with solar PV and battery storage in St Ives — particularly at Carbis Bay where south-facing aspects and large roof areas align — creates an exceptionally strong financial case. See our combined guide and BUS grant explainer.
