What Green Grid Innovations does

Green Grid Innovations Ltd is a Sheffield-based UK private limited company that has developed and patented a 24V flexible heating technology capable of generating heat up to and beyond 100°C from low-voltage power, with a product focus on domestic hot water and adjacent heating applications. The company sells retrofit self-adhesive heater pads that attach to existing hot water cylinders in place of conventional immersion heaters, maintaining water temperature between 60°C and 63°C, and co-develops new hot water cylinders with Newark Copper Cylinders that ship with Green Grid heating elements pre-fitted. A second product line, the Green Grid Hub, is a beta monitoring dashboard that visualizes voltage, current, power, temperature, and usage data and allows remote on/off control of installed systems.

The company monetizes primarily through direct hardware sales, operating on a quote-based model where customers outline requirements via the website and the company or its installation partners deliver and fit the system. Certified installation partners, including J&J Crump & Sons, handle field deployment of retrofit units, while the monitoring system is positioned for both residential and broader industrial and commercial use cases such as railway de-icing. The company also has a forward-looking clean cooking appliance project for Sub-Saharan Africa oriented around solar PV-connected e-cooking. The website is the primary marketing channel, pricing is not publicly disclosed, and no funding rounds, headcount, or revenue figures are available in the source data.

Core offering

Green Grid Innovations designs, manufactures, and sells low-voltage 24V heating systems for domestic hot water cylinders, new hot water cylinders, and clean cooking appliances. Its products use patented flexible heating pads that operate at low power and can be powered directly from renewable sources such as solar PV. The company also offers the Green Grid Hub monitoring dashboard and a configurable remote monitoring system for industrial and commercial applications.

Product overview

Green Grid Innovations offers a portfolio of renewable heating products centered on their patented 24V flexible heating technology. The core portfolio consists of the Retrofit Hot Water Cylinder System (low-power heater pads for existing cylinders), New Hot Water Cylinders (manufactured with Newark Copper Cylinders), and Clean Cooking Appliances (e-cooking solutions for Sub-Saharan Africa). The offering is supplemented by the Green Grid Hub monitoring dashboard and Monitoring System for remote data capture and control. All products are designed to work with renewable energy sources, particularly solar PV.

Brands

• Green Grid Hub: A personalised monitoring dashboard (beta) for real-time monitoring and control of heating systems.

Products and services

• Retrofit Hot Water Cylinder System 24V 130W insulated self-adhesive heater pads retrofitted to existing domestic hot water cylinders in place of the immersion heater, maintaining water temperature between 60°C and 63°C. Sized at 1 pad per 50L of water capacity. Designed for UK homeowners and installers seeking low-power, renewable-compatible hot water heating.
• New Hot Water Cylinders New hot water cylinders pre-fitted with Green Grid Innovations heating elements as standard, designed in collaboration with Newark Copper Cylinders. Compatible with multiple heat sources including solar PV, mains electric, heat pump, gas, or oil. Targeted at homeowners replacing existing cylinders and at new-build projects.
• Clean Cooking Appliances E-cooking appliance project for Sub-Saharan Africa and beyond, designed with significant emphasis on solar PV connected systems and features that maximize cooking efficiency using renewable energy. Targeted at households in regions lacking clean cooking solutions.
• Remote Monitoring System Remote data capturing system developed with leading communication device developers, providing high-precision measurements of voltage, current, power, and temperature with real-time data storage, historical visualization, remote on/off toggling, and configurable inputs. Marketed as a bespoke solution for industrial and commercial machine monitoring.

Scale indicators1 record

Recent moves6 records

Expansion highlights5 records

Emerging players

• BURN Manufacturing: East Africa-based clean cookstove and clean cooking appliance manufacturer. Comparable as a peer in the Sub-Saharan Africa clean cooking segment where GGI has its e-cooking appliance project, with BURN being a more established commercial-stage player.

Broad incumbents

• Gledhill: Established UK manufacturer of hot water cylinders and thermal storage products. Comparable as a scaled incumbent in the same domestic hot water equipment market where GGI sells its retrofit and new-build solutions.
• Daikin (UK): Global heat pump and air conditioning manufacturer with strong UK presence. Comparable as a primary low-carbon residential heating incumbent whose heat pumps compete for the same policy-driven shift away from gas boilers.
• Worcester Bosch: Major UK supplier of boilers, heat pumps, and hot water systems. Comparable as the dominant incumbent whose installed base and installer network GGI's retrofit offering must displace to scale.
• Viessmann: Global manufacturer of heating, industrial and refrigeration systems, including heat pumps, boilers, and solar thermal. Comparable as a broad incumbent offering renewable-integrated heating solutions across residential and commercial markets in the UK and Europe.
• Octopus Energy (Heat Pump / Cosy): Major UK energy retailer and heat pump installer (Octopus Cosy). Comparable as a residential low-carbon heating provider competing for the same end customer seeking to replace gas heating with renewable-integrated solutions.

Direct peers

• Sunamp: UK-based manufacturer of thermal energy storage (heat batteries) for domestic hot water and space heating. Comparable as an alternative low-carbon residential heating technology targeting the same decarbonization-driven replacement of gas boilers and inefficient immersions.
• Mixergy: UK-based smart hot water cylinder manufacturer focused on energy-efficient, on-demand hot water heating. Directly comparable to Green Grid Innovations as both target the residential domestic hot water market with technology-driven efficiency claims and smart monitoring/control capabilities.
• Newark Copper Cylinders: UK hot water cylinder manufacturer and Green Grid Innovations' core OEM partner. Comparable as a domestic hot water cylinder producer serving the same residential market; relevant as a current channel partner and potential competitive vector if Newark expanded its own heating technology in-house.

Others

• HeatGeek / Heat Pump installers: UK heat pump education and installer community that influences consumer decisions toward heat pump adoption. Comparable as an adjacent ecosystem participant shaping the same low-carbon heating market narrative that GGI's electric heating alternative must compete within.
