Renewable Energy for Homeowners – Cornwall - GreenR Renewables

Clean power, lower bills, and energy independence. We help you run your home on your terms.

It is one thing to want a more energy-efficient home. It is another to figure out how to make it happen without the jargon, the gimmicks, or installers that don’t return your call.

At GreenR Renewables, we get it. You are not just swapping out a system - you are investing in comfort, energy independence, and the kind of home that runs smarter, cleaner, and cheaper year after year. We specialise in full renewable setups designed around Cornish homes - whether you are tucked away off-grid or halfway through a renovation.

We are not a national chain. We are locals. Engineers by trade and green energy obsessed by nature. We are proud to bring dependable, low-carbon solutions to homes across Cornwall - from Padstow to Bude, Wadebridge to Bodmin.

Services Designed for How You Live

We don’t believe in half-measures or ‘that’ll do’ installs. Our systems are practical, compatible, and built to grow with you. And if you're not sure what fits your home? That’s exactly what we are here for.

Heat Pumps

Say goodbye to oil or LPG. Our systems give you reliable, low-carbon heating for homes that need proper warmth, without the constant top-ups. We will help you compare heat pump vs boiler, explore ground or air source heat pump options, and make sure everything works quietly in the background - radiators, underfloor heating, and all.

Solar PV

Generate your own power with a rooftop solar panel installation that actually fits your roof (and doesn’t spoil the view). Whether you want to save money with solar panels or get a solar panel quote for your home, we will sort a battery-ready setup that’s designed for Cornwall’s light, not California’s.

Battery Storage

Tired of sending free electricity back to the grid? Store excess solar energy for the evenings, power cuts, or just peace of mind. Whether it’s a compact lithium-ion home battery or a full hybrid solar battery system, we will make sure it earns its keep.

MVHR (Ventilation)

Sealed homes need to breathe - but not at the cost of heat or comfort. Our home heat recovery systems keep air clean and balanced, especially in modern airtight builds. No more draughty vents or noisy fans. Just better air.

EV Charging

We install home EV chargers that work hard and look good. Want one that syncs with your solar? No problem. Need advice on charger types or want to future-proof for your next car? That’s our bread and butter.

Underfloor Heating

Smooth, invisible comfort underfoot - the kind that makes you forget what cold floors used to feel like. We install wet underfloor heating systems that pair perfectly with heat pumps and work beautifully in retrofits or new builds.

Energy Diversion

Why send solar back to the grid for pennies when you could heat your water for free? We install energy diversion controllers (like Eddi) that make the most of your power, hot water, batteries, or even your EV.
What We Help You Solve

Let’s be honest - the energy landscape is confusing. Misinformation. Horror stories. Too many options. We help cut through the noise.

Still running on oil or LPG? We will help you move to a proper renewable heating system and reduce heating bills sustainably, without compromising on warmth.

Solar system, but nobody is home all day? Add a solar battery and maximise solar self-consumption instead of wasting it.

Condensation or stuffy air in a modern extension? MVHR for airtight homes keeps air fresh without letting heat escape.

Tired of fighting for a spot at the public EV charger? Charge your EV at home with a wallbox installed neatly by us.

Hot water still costing you money? Use solar power efficiently with an immersion diverter that gives you free hot water from PV.

We don’t just solve technical issues - we help you feel confident, comfortable, and in control.

Why Homeowners Like You Choose Us

You are not looking for a quick fix. You are creating a home that works better for you, your family, and the future. Here’s how we help:

We listen - No assumptions. We ask questions. We visit your home (if you’d like). We explain what’s possible without the hard sell.

We design - From battery-ready solar installation to whole-house underfloor heating, we plan systems that fit - not ones that force you to adapt.

We install - Clean, tidy work. Pipework that looks sharp. Cables tucked away. We are not in a rush - we care how it all turns out.

We stay on your side - Need to tweak something after install? Want to add a battery later? We are still here, and we answer the phone.

You might be:

A family juggling costs and comfort

A retiree wanting fewer energy surprises

A nature-loving couple making a greener choice

A self-builder who wants it done right from the start

And if you are not quite sure what fits, we will help you figure it out.

Cai and Richard, at GreenR Renewables are amazing! I had a heat pump and solar panels installed with an EDDI. They talked through everything, so that even I could understand the technology and its everyday usage. The savings I'm making through the solar installation is great and how they set it up for the solar to help with the running of the heat...

Nicky B

Super happy with my Vaillant Heat Pump install. The unit is incredibly quiet and you can hardly tell it’s running and it’s also turning out to be super efficient.. I doubt there’s anyone else around who knows as much as these guys and you can be rest assured it’ll be designed correctly unlike others I’ve seen. They also made the Governmen...

Julian Teague

Just had an air source heat pump and hot water cylinder fitted by GreenR Renewables. The team have been great from start to finish. We sought out GreenR due to their heat geek certification after having several quotes from companies who didn't really seem to be clued up on fitting heat pumps. Having a fair amount of knowledge of ASHP ourselves, G...

Jamie Robinson

We engaged with Richard and Cai recently to fit our solar system on my new build property. I was impressed from the start with the communication and great advice on different systems available and the benefits to each. Once we had chosen an option they were quick to have the package available and ready to fit, working around us on site as to when w...

Ben Teague

Really pleased with the install, carried out by professional knowledgeable engineers. High standard of work and took the time to communicate with us, highly recommend them.

Richard Charman

The guys from GreenR Renewables did a fantastic job fitting our solar panels. They were quick, efficient and professional. Richard's expertise and advice really helped us decide on the right system to install. Highly recommended!

Peter New

Cai and Richard have recently installed an air source heat pump for us - their service was second to none! We can’t recommend them highly enough. They dealt with the grant application for us and have been an absolute pleasure to deal with. They really know their stuff!

Mandy Ellicott

Richard and team fitted a 4.8kw solar system for me recently. I'm very happy with the quality of the kit supplied and the guy's did a brilliant job. Can't fault anything at all! They even took all the boxes and rubbish away! Never had an electrician do that before. FIVE STAR service 👌 Would highly recommend.

Chris Kendall

GreenR Renewables did an outstanding job increasing our battery storage capacity with the Pylontech US5000 4.8kW system. The team of engineers was punctual, efficient, and went above and beyond to ensure the installation was completed smoothly. Their attention to detail and dedication to customer satisfaction was truly commendable. Their commitmen...

Bob Willingham

We have worked with the team at Green R Renewables on multiple projects now and their work is always impeccable. There is a genuine care behind the installation with the customers priorities always at the forefront. We always recommend their services to our customers and will continue to do so!

Bowden Architecture

Installation of solar panels plus battery. The team provided great advice prior to us making a decision. Installation went very smoothly with suitable scaffolding in place (which also allowed inspection of the finished work). Post installation is also very good & responsive. We are very happy with the new system.

Kevin Brown

I recently had the pleasure of working with GreenR and was thoroughly impressed by their professionalism and extensive knowledge in the renewables sector. They provided fantastic service at competitive prices, making the entire process seamless and efficient. I will definitely be working with them again in the future.
