Battery Storage Installation in Padstow

Battery Storage in Padstow: The Holiday-Let Economics

Padstow (PL28) is one of Cornwall's premier holiday destinations, and its housing stock reflects that — a high proportion of second homes and holiday lets around the harbour, plus 20th-century bungalows and modern detached properties at Trevone, St Merryn, Constantine Bay and Harlyn Bay. For a property earning letting income, every kilowatt-hour bought from the grid eats into the margin, which makes battery storage unusually attractive here. CCS Heating & Renewables installs Foxstar, Tesla Powerwall and FoxESS systems across the whole PL28 area from our Pool base, 20 miles away.

Summer Generation Meets Peak Occupancy

Padstow's letting season peaks in exactly the months solar generates most. At around 1,298 kWh/m2/year — roughly 19% above the UK average — a 5kWp array on a Padstow roof produces a strong summer surplus. Without a battery, most of that daytime generation is exported for a few pence while guests draw expensive grid power in the evening — cooking, showering, charging devices, running the TV. A 9.5–13.5kWh battery captures the daytime surplus and releases it into that evening peak, delivering near energy-independence in July and August and typically saving £500–£900 a year on a busy let.

Off-Gas Padstow: 88% and Rising

An exceptional 88% of Padstow homes are off the mains gas grid — almost the entire town runs on oil, LPG or electric heating, with a growing number of heat pumps. That makes the solar-plus-battery-plus-heat-pump stack especially powerful here: solar generates, the battery stores, and the heat pump heats the home and hot water from stored solar rather than costly grid electricity. For owner-occupiers in the older harbour cottages and the Trevone and St Merryn bungalows, it is the most effective way to cut a heating bill that would otherwise depend on volatile oil prices.

Coastal Siting & Equipment

• Indoor mounting: batteries are installed in a garage, utility room or plant space, so the salt-laden Atlantic air at Harlyn and Constantine Bay never reaches the unit — only the rooftop solar needs marine-grade specification.
• Holiday cottages & harbour properties: often listed or within the conservation area — we position equipment discreetly and handle any planning paperwork.
• Second homes & modern detached: larger roofs and driveways suit combined solar, battery and EV charging in one visit.

One Visit, Maximum Return

For owners planning solar and an EV charger, adding a battery at the same time is the most cost-effective route — one installation visit, one set of DNO notifications, and no repeat scaffolding. Battery storage installed with solar carries 0% VAT until 31 March 2027, export is paid through the Smart Export Guarantee, and CCS handles the G99 DNO notification and MCS certification.
