Renewable Energy for Architects – Cornwall – GreenR Renewables

Design-led systems. Engineer-backed thinking.

When you are designing a home with purpose, every decision counts - the junctions, the flow, the light, the way a detail meets the eye. Renewable systems should fit into that logic, not fight it. That is where we come in.

We are not just here to sell off-the-shelf systems – we want to collaborate on the design and build of truly sustainable homes.

At GreenR Renewables, we work alongside Cornwall’s architects to help integrate heat pumps, solar panels, MVHR and more into contemporary and traditional projects. Whether you are at sketch stage or dealing with SAP headaches post-planning, we are here with clear input, neat coordination, and the sort of care that shows on site.

What We Do - and How It Supports You

We don’t just install renewable tech. We design it around your vision.

Working across Bude, Wadebridge, Polzeath, and everywhere in between, we bring MCS-accredited engineering, CAD support, and detail-conscious advice to architects who want performance without compromise.

Here’s how we help:

Heat Pumps

We’ll size it properly, design around your heat emitters, and keep flow temps low. Neat plant room layouts, discreet external units, and quiet operation - all with drawings that slot into your floorplans.

Solar PV

Flush-mount? In-roof? We’ll help you decide what works with your structure and planning needs. We’ll also make sure your SAP points are covered and everything plays nicely with future battery upgrades.

MVHR

Tidy ductwork, carefully placed grilles, and full commissioning to Part F standards. We route through service zones, coordinate with structure, and keep everything as invisible as you want it.

Battery Storage

Wall-mounted, modular, and not as space-hungry as you might think. We'll connect it into the wider system - solar, EV, hot water - and provide load balancing strategies for smart homes that actually work.

EV Charging

We plan for it early - first-fix cables, load management, charger choice. Want to integrate with PV? No problem. Need something subtle for a clean façade or future-ready garage? Already thought of that.

Underfloor Heating

Proper UFH design for energy-efficient buildings - flow temps matched to your system, loops sized per room, screed types considered, and manifold placement that doesn’t kill a utility space.

Energy Diversion & Smart Controls

Solar diverter system design, hot water prioritisation strategies, and user-friendly energy control that doesn’t overwhelm clients. We'll handle the logic and the layout - you keep control of the look and feel.
The Frustrations We Can Help You Avoid

You’ve probably been here before...

The PV spec looks great… until you see the mounting details.

Your layout’s tight and the ductwork doesn’t care.

Clients want EV charging but no one’s spoken to the electrician.

SAP assessors push for renewables but can’t tell you how to actually fit them in.

The plant room’s been sketched after the build started.

We see it all the time. And we’ve built our service around solving it - by speaking your language early, giving you the drawings and logic you need, and staying involved through handover.

Tailored for How You Work

You don’t need another contractor - you need a renewable energy partner who respects your process.

Here’s how we typically slot in:

RIBA Stage 2-3

We’ll review your plans, advise on floor buildup, emitter strategy, EV infrastructure, and space planning for duct routes or plant

RIBA Stage 4

We’ll provide specs, CAD blocks, performance figures and tidy narrative to help with planning, SAP, or M&E coordination

RIBA Stage 5+

Our install team takes over, working cleanly and carefully, with full commissioning, client handover packs, and post-install support

If you’re designing low-energy homes in Cornwall, we are ready to support your detailing with a level of care that makes a difference. And if your project’s already moving, we’ll catch up fast and get the renewables properly in hand.

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

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

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

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

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...

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

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

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!
