Hex Energy

What Hex Energy does

Hex Energy Limited is a privately held UK renewable energy contractor founded in 2015 and headquartered in Nuneaton, Warwickshire. The company designs, supplies, installs, and maintains heat pump systems — ground source (GSHP), air source (ASHP), and water source (WSHP) — alongside solar photovoltaic (PV), battery storage, underfloor heating (UFH), and Mechanical Ventilation with Heat Recovery (MVHR). A defining technical capability is in-house Certified Geoexchange Design, held by CEO Andy Howley (IGSHPA/AEE certified, author of the GSHPA Vertical Borehole Standards 2011), enabling bespoke ground array design, drilling supervision, and Thermal Response Testing without external consultants. The company delivers projects from feasibility and design through turnkey installation and ongoing planned preventative maintenance.

Hex Energy serves a dual market: residential homeowners (new builds and retrofits, including heritage properties up to £100k+) and commercial/public-sector clients including schools, colleges, councils, manufacturers, and hospitality venues. Notable projects span a 90kW mono-bore open loop GSHP at Kering's Mayfair offices, a 200kW factory system at Litecast of Nuneaton, 420kW college retrofits under the Public Sector Decarbonisation Scheme, and multi-building decarbonisation for Calderdale Council. The commercial pipeline is anchored by DfE and PSDS government frameworks, with the Boiler Upgrade Scheme (£7,500 grant, 0% VAT on heat pumps) supporting residential demand.

The business model combines one-time installation revenue (turnkey project sales priced per kW: £1,200/kW ASHP to £2,700/kW vertical GSHP commercial) with recurring service and maintenance contracts. Distribution is direct-to-customer only — via website quote requests, phone, email, exhibitions (Grand Designs, Home Building and Renovation Show), and tender processes — with no reseller network. Marketing emphasis is on content/education (blog, CPD sessions, case studies) and Google social proof (4.8 rating, 27 reviews). MCS, Constructionline Gold, SSIP, and Octopus Energy Partner accreditations are prerequisites for accessing UK government grant schemes and underpin Hex's positioning in the regulated decarbonisation market.

Revenue model

1. Heat Pump System Installation: Hex Energy generates revenue primarily through the design, supply, and installation of bespoke heat pump systems (ground source, air source, and water source) for residential and commercial properties. Turnkey installations include ground array (drilling/trenching), heat pump unit, buffer vessels, pipework, controls, and commissioning.
2. Service, Maintenance and Repairs: Recurring revenue from servicing and maintaining commercial and residential heat pump systems. The company offers planned preventative maintenance (PPM) programmes, reactive repairs, water quality testing, and system monitoring to maximise lifespan and efficiency.
3. Solar PV and Battery Storage: Revenue from designing and installing solar photovoltaic systems and battery storage, often paired with heat pump installations as complementary renewable energy solutions.
4. Underfloor Heating and MVHR: Installation of underfloor heating systems and Mechanical Ventilation with Heat Recovery (MVHR) units, often bundled with heat pump projects or sold as standalone services.

Products and services

• Ground Source Heat Pumps (GSHP) Heat pump systems that harness energy from the earth through horizontal trenching or vertical boreholes, providing heating and cooling for residential and commercial properties. Delivered as a turnkey design and installation service.
• Air Source Heat Pumps (ASHP) Heat pump systems that extract heat from outside air to provide heating and hot water for residential and commercial properties, offering a practical and lower-cost renewable heating solution.
• Water Source Heat Pumps (WSHP) Heat pump systems that draw energy from nearby water bodies for heating and cooling applications, including open loop and lake loop configurations.
• Solar Photovoltaic (PV) Systems with Battery Storage Solar PV panel systems that convert sunlight into electricity to power properties, typically paired with battery storage for energy independence and often integrated with heat pump installations.
• Underfloor Heating Systems Water-based underfloor heating systems that distribute warmth evenly through pipes beneath floors, providing room-by-room control and operating at the low temperatures ideal for heat pump systems.
• Mechanical Ventilation with Heat Recovery (MVHR) Ventilation systems that extract stale indoor air and replace it with filtered, warmed outdoor air while recovering heat, enhancing indoor air quality and overall building energy efficiency.
• Heat Pump Service, Maintenance and Repairs Ongoing planned preventative maintenance, reactive repairs, water quality testing, and system monitoring for residential and commercial heat pump installations to maximise lifespan and efficiency.
