Why Par & St Blazey Homeowners Are Switching to Heat Pumps

Par & St Blazey is one of the towns covered by our county service — see heat pump installation in Cornwall for costs, standards and the full picture.

Our Home Territory

CCS Heating & Renewables is based in Pool, Redruth, and covers Par, St Blazey and the wider PL24 postcode. We know these properties, roads, and roof types better than anyone. For Par and St Blazey homeowners, that means faster survey scheduling, lower travel costs, and engineers who live and work in the same community.

The Eden Project Effect

The Eden Project — located 1.5 miles from St Blazey gate — is one of the world's most visible renewable energy advocates. Eden is actively developing the UK's first commercial deep geothermal energy project, drilling to extract heat from the granite bedrock beneath Cornwall. The project is a powerful local endorsement of renewable heating technology and has made Par and St Blazey homeowners unusually well-informed about heat pump benefits.

Off-Gas Properties: A Strong BUS Grant Market

With approximately 60% of Par and St Blazey homes off the mains gas grid, this area has one of the highest off-gas rates in mid-Cornwall. Properties currently on oil, LPG, or direct electric heating are eligible for the up-to-£9,000 Boiler Upgrade Scheme grant when switching to an air source heat pump. We handle the grant application end-to-end — you simply deduct the voucher value from your installation invoice.

StARR Flood Scheme: Equipment Placement Considerations

Par is one of the lower-lying communities in mid-Cornwall and parts of the town are in flood risk zones. The £35 million StARR (St Austell Rivers Regeneration) scheme is actively managing flood risk, but it means that for some Par properties, the placement of heat pump external units and hot water cylinders requires careful survey assessment to avoid flood-susceptible locations. Our engineers assess this as standard during the free survey visit.

Common Questions

Frequently Asked Questions About Heat Pumps in Par & St Blazey

01
How much does it cost to fit a ground source heat pump in Cornwall?
A complete ground source installation in Cornwall is typically £18,000-£32,000 before grants: £11,500-£16,800 for the heat pump, cylinder, controls and commissioning, plus £6,000-£14,000 for trenched or slinky ground loops or £12,000-£22,000 for vertical boreholes. The Boiler Upgrade Scheme takes £7,500 off, or £9,000 until March 2027 if you are replacing oil or LPG and have no mains gas connection, and installations in homes are zero-rated for VAT until 31 March 2027.
02
What are the downsides of a ground source heat pump?
Two, mainly: cost and disruption. The ground array is most of the extra money over an air source system, and it means either trenching roughly 2.5 times your heated floor area or drilling boreholes. On a small garden the trench option disappears and drilling is the only route. Against that, the heat pump sits indoors with no outdoor unit, seasonal efficiency is typically 4.0-4.8 against 3.0-3.5 for air source, and the buried loop long outlives the heat pump itself.
03
How much land do you need for a ground source heat pump?
For horizontal collectors, roughly 2.5 times the heated floor area of the house, trenched at about 1.2-1.5 m deep — so a 150 m² house needs something like 375 m² of diggable ground. Slinky coils fit the same collector length into shorter trenches. Where there is no land, vertical boreholes of typically 90-150 m each replace the trenches and take a fraction of the surface area.
04
Is ground source better than air source in Cornwall?
It is more efficient and more expensive. Ground temperatures here stay around 9-12°C all year, so a ground source system runs at a seasonal efficiency of about 4.0-4.8 against 3.0-3.5 for air source, with no outdoor unit and no noise assessment. Air source costs roughly half as much to install and fits any property. Since the Boiler Upgrade Scheme now pays the same for both, the decision comes down to available land, disruption and how long you will own the house.
05
Do I need planning permission for a heat pump in Cornwall?
Air source heat pumps on houses are permitted development under Class G of Part 14 of the GPDO as amended on 29 May 2025 — one unit on a terraced or semi-detached house, two on a detached house, up to 1.5 cubic metres, meeting the MCS 020 a) standard including a 37.0 dB(A) limit at a neighbour's window. In a conservation area or the Cornwall and West Devon Mining Landscape World Heritage Site the unit cannot go on a wall or roof fronting a highway, or nearer a highway than the house. Listed buildings need permission. Ground source heat pumps have no Part 14 limits.
