Planning to fit a heat pump? Adding solar panels and a battery? Switching off gas for good? That all sounds great on paper, but it only works as well as the wiring and pipework behind the scenes.
Gas and Electrical Works
-
It is a fact, proper gas and electrical work is the backbone of a good renewable energy system
At GreenR Renewables, we are not general sparkies or heating engineers offering renewables on the side. We are a Cornwall-based team of certified specialists who design, wire, commission, and integrate low-carbon systems, specifically for you. Whether you are after a new EV charger or need help to safely disconnect a gas boiler, we handle it all in-house. Properly.
We take pride in the details. Not just the ones you see, but the ones that keep your home running quietly, efficiently, and reliably for years to come.
Gas and Electrical Services Tailored to Low-Energy Homes
Serving Cornwall homeowners from Bude to Boscastle, Wadebridge to Padstow and beyond.
We design and deliver the sort of technical work that many tradespeople steer clear of - because when it comes to renewables, it is not just about “getting it working.” It is about getting it right.
Here is what we offer, and how it all connects.
Electrical Installations with Renewables in Mind
We are specialist renewable energy electricians in Cornwall that homeowners trust. Every install is certified and carefully planned.
Our consumer units are designed with renewable energy systems in mind; neat, labelled work you can understand at a glance.
We regularly carry out:
- Upgrades to accommodate air source heat pumps
- Safe integration of solar PV wiring and battery systems
- EV charger installations (Tesla and more)
- MyEnergi Eddi diverter wiring for solar hot water
- Smart heating controls and zoning circuits
- MVHR wiring for mechanical ventilation
- Full electrical schematics, testing, and Part P sign-off
Every detail is planned with longevity and serviceability in mind, so your system works as beautifully as it looks.
Specialist Gas Engineering With a Low-Carbon Focus
If you are keeping a gas boiler for now, we will make sure it works safely alongside your renewables. If you are ditching gas entirely, we will take care of that too.
We also support step-by-step decarbonisation. If you are planning to switch to a heat pump in future but keeping your boiler for now, we will set up your system so that changeover is simple, safe, and smooth when the time comes. From optimised pipe layouts to hybrid-ready controls, we design for today and tomorrow, so you are not paying twice to undo rushed or incompatible work.
As gas engineers for hybrid heating systems, we know the difference between a temporary setup and a well-planned, phased transition.
Typical work includes:
- Capping and safely decommissioning gas appliances
- Rerouting pipework for low-temperature UFH setups
- Supporting hybrid heat pump and boiler systems
- Ensuring Gas Safe compliance across all work
We know how these systems behave in the real world and how to prepare for what’s next.
Designed Around You — and Your Home
Whether you live in a stone-built cottage or a timber-framed self-build, we tailor our approach to suit the building, your goals, and how you want to live.
Here’s how we usually work:
Design & Planning
We look at your whole setup — not just the bit we are wiring. That includes load checks, routing plans, and smart layout decisions based on how you’ll actually use the system.
Preparation
We carry out any disconnections, pipe rerouting, or inspections before install day, so the main work runs smoothly.
Installation
Work is carried out by qualified electricians and Gas Safe engineers. Everything is tested, documented, and explained.
Commissioning & Handover
You will get a complete walkthrough, certification pack, and help setting up your apps or controls. If something is not clear, we are just down (or up) the road.
Local Stories From Local Homes

- Questions We Often Hear
-
Can’t my usual electrician do this?
Maybe - but unless they’ve worked with batteries, diverters, or heat pumps, chances are they’ll miss key steps or delay your sign-off. We’ve seen it too many times. We do everything in-house, from start to finish.
Is electrical work included in your solar or heat pump quotes?
Yes, all essential electrical and gas works are included. Optional extras (like EV circuits or diverters) are priced clearly.
Will I lose power during the work?
Briefly, yes - but we’ll let you know ahead of time and keep disruption to a minimum.
Do you work in remote or rural areas?
Absolutely. We’ve installed systems in off-grid cabins and farms across Cornwall. We know how to handle limited grid supply and get creative when we need to.
Can I just book you for electrical upgrades?
Yes. We offer standalone works too — from solar PV retrofits to underfloor heating controls and wiring.
