Expert Renewable Maintenance – Heat, Solar & More - Cornwall

The Complete Care Package for Your Renewable Systems

If you have invested in renewables, you have already taken a big step toward a cleaner, lower-cost future. But like any smart home upgrade, your systems need care to keep performing at their best.

At GreenR Renewables, we provide expert, joined-up servicing, preventative maintenance and repairs for homes across Cornwall - from heat pumps and MVHR to solar PV, battery storage and more. Whether it is a routine heat pump service, solar PV check-up, or tuning your MyEnergi Eddi, every visit is led with technical precision and clear communication.

One Visit. Total Peace of Mind.

Renewable systems often work together – your aftercare should be just as well coordinated. Our qualified, MCS and Heat Geek certified engineers understand how your technologies interact.

We check the bigger picture, not just one piece at a time.

We service homes in Bude, Padstow, Wadebridge, Bodmin and beyond.

What We Cover

Heat Pump Servicing (Air Source & Ground Source)

We check flow rates, refrigerant levels, controls, filters and performance. If your system’s struggling to heat efficiently, we’ll spot it, and fix it.

✔ Full system diagnostics
✔ Flow rates and pressures
✔ Filter and strainer cleaning
✔ Control optimisation

Solar PV Checks

We assess panel condition, inverter output and generation performance. A drop in solar yield often points to a fault we can catch early.

✔ Inverter checks and output testing
✔ Panel inspection (debris, corrosion, wear)
✔ Isolation switch function testing
✔ Generation data report

MVHR System Maintenance

Filters, air balance and fan performance all matter here. We help stop stale air, noise or inefficiency in its tracks - often with just a small adjustment.

✔ Ventilation balance and airflow tests
✔ Filter cleaning/replacement
✔ Heat exchanger and ducting check
✔ User control review and guidance

Home Battery Storage Health Checks

Charging and discharging cycles, firmware, safety checks - your battery deserves the same attention as your panels and pump.

✔ Charge/discharge cycle review
✔ Firmware updates
✔ Safety checks on wiring and housing
✔ Performance efficiency report

EV Charging Points

We test functionality, fault indicators and connectivity — whether it is a charger at home or multiple units on a shared development.

✔ Load testing and fault diagnostics
✔ RCD and isolation safety tests
✔ Smart charge settings support
✔ Cable condition and software updates

Underfloor Heating

Flow calibration, control testing and manifold inspection all help keep your home evenly warm without excess energy use.

✔ Circuit performance and heat distribution
✔ Thermostat and sensor review
✔ Pump and manifold inspection
✔ Flow rate calibration

Solar Diversion Devices

If your diverter isn’t sending energy where it should, we’ll optimise it. Small changes can mean better savings and smarter usage.

✔ Real-time performance and calibration
✔ Firmware updates
✔ Grid-tied settings review
✔ Solar-to-load balancing advice
What Often Goes Wrong (and How we Help)

Even the best systems need attention now and then. Common issues we are called out for include:
- Unclear servicing schedules — “Am I supposed to get this checked every year?”
- Systems underperforming — higher bills, poor heating, low solar output
- Warranty worries — not sure what needs doing to keep them valid
- Confusion after a build — unclear documentation or no proper handover
- Juggling contractors — different systems, different companies, no joined-up care
- Minor issues becoming big ones — blocked filters, diverter faults, inefficient controls
- We make maintenance easy to manage — combined visits, clear reports, and a service that feels built around you.
Designed Around You

Whether you have just finished building or have lived in your home for years, you want the same things: reliability, low bills, and the confidence that your systems are doing their job.

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

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 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

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

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

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

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.

Luke Cowling

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

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

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

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

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!
