Rawlings Renewables is a renewable energy installer serving Hampshire. We design and fit air and ground source heat pumps, solar PV and HVO fuel systems for homes and businesses.
Free and no obligation — tell us about your property and we’ll be in touch.
We fit heat pumps, solar panels and HVO systems across Hampshire that cut running costs and emissions together. Every project is a real step towards a more sustainable property.
Heat pumps are at the heart of what we do. Our air source heat pump installation service suits most homes, drawing heat from the outside air to run your radiators and hot water, while ground source heat pumps use buried loops for steady, highly efficient heating where there’s the land for it. Every system is sized from a room-by-room survey, and we look after it afterwards with heat pump servicing and maintenance for any make.
Explore heat pumps →Solar panels let you generate your own electricity and cut what you buy from the grid, and paired with a heat pump they can cover a good share of its running costs. We handle solar panel installation from design and panel layout through to optional battery storage, so the system fits your roof and the way you use energy.
Explore solar PV →Not every property suits a heat pump straight away. HVO fuel is a renewable, drop-in replacement for heating oil that cuts emissions without replacing your boiler. We also fit swimming pool heat pumps and domestic air conditioning, and offer renewable solutions for developers working on new-build sites.

Three steps: a home survey, a tailored design with grant guidance, then installation and handover.
We start with a home visit. We check the insulation, room sizes and current heating setup, then build our recommendation around what your home actually needs.
We design the system around your property, then tell you straight what grants apply, including the Boiler Upgrade Scheme’s up to £9,000 towards a heat pump.
Installation is completed with minimal disruption. We then walk you through maintenance and warranties, so you’re confident from day one.
We went to Rawlings for a quote because they treated us so well when buying oil, and their quote was much better than others. Joe and Rowan explained everything in detail. We chose the coldest week of winter to install and they arrived with fan heaters for us. They took away the oil boiler, tank, old cylinder and radiators and fitted the new ones with minimum disruption. We can't praise them highly enough — a lovely, evenly warm house with hot water that's perfect for our needs.

Rawlings installed a Samsung 16kW air source heat pump for us at the end of January 2025. The project went smoothly and finished ahead of schedule. The installation team was professional, efficient and respectful of our home. Great job, thanks!

From start to finish the whole process was smooth and efficient, and the team was incredibly professional. The project was finished exactly as promised, both in timing and cost — no hidden fees and no surprises, just a job well done. I highly recommend Rawlings Renewables for reliable, hassle-free installation.

We handle every stage ourselves: site visit, design, sourcing, fitting and after care. One team throughout, whether it’s solar PV installation or a full heat pump system.
No call centre here, just a family run team. As a renewable energy installer, we focus on the basics: proven technology, lower running costs, grant support, low maintenance systems, and certified installations. We’re local, family run, and built on repeat customers, not one off jobs.

Lower Running CostsHeat pumps and solar cost less to run than gas or oil, month after month.
Grant SupportMany installations qualify for grants, including the Boiler Upgrade Scheme, cutting upfront costs.
