Heat Pump & Solar Installers in Grantham

Homes in Grantham face the full range of the East Midlands climate: cold, damp spells through winter that push any heating system hard, followed by long, mild shoulder seasons in spring and autumn where an efficient system quietly saves you money. A modern air source heat pump is built for exactly this pattern. Rather than blasting heat in short, expensive bursts like a gas boiler, it delivers gentle, continuous warmth at a low flow temperature — which is both more comfortable and far cheaper to run. Every system we design for a Grantham home is sized from a full room-by-room heat-loss calculation, so it is matched to your property rather than a rule-of-thumb estimate.

Much of Grantham is made up of characterful period and stone-built homes alongside newer developments on the edges of the town. Heritage properties reward a careful, sensitive approach: discreetly sited outdoor units, thoughtful pipe routing, and low-noise R290 equipment that respects both your home and your neighbours. We survey the fabric of the building first and design around it, so you keep the character of your Grantham home while gaining clean, low-cost heat and, where the roof allows, a discreet solar array.

Running costs are where Grantham homeowners tend to see the biggest change. Many properties here are off the mains-gas grid, relying on oil, LPG or older electric heating — the most expensive ways to heat a home. Switching to a heat pump typically cuts those running costs sharply, and because off-gas-grid homes qualify for the enhanced £9,000 Boiler Upgrade Scheme grant (available for applications from 21 July 2026 to 31 March 2027), the upfront cost of going green in Grantham has never been lower. We handle the entire grant application on your behalf and deduct it from your invoice, and solar and battery storage carry 0% VAT until 2027.

We install right across Lincolnshire, bringing the same engineering-led standards to Grantham that have made us one of the region's most trusted renewable energy specialists. Getting started is simple: begin with a free online estimate to see the likely system, savings and grant for your home, with no cost and no obligation. When you are ready for an exact price, our £250 home survey delivers a full room-by-room heat-loss assessment and a bespoke system design — and that fee is fully refunded when you go ahead with your installation. From there we handle everything, from MCS certification and grant paperwork to Building Control and DNO notifications, with lifetime monitoring and annual servicing to keep your system efficient for years to come.
