Schools and public buildings
Develop heating and hot-water strategies around occupancy, safeguarding, site constraints and the delivery programme.
Commercial systems
Heating, cooling and heat recovery—engineered around your site.
Thermal Earth can develop site-specific heating, cooling and heat-recovery strategies for schools, apartment buildings, factories, offices and data centres—then shape the design and delivery route around the operation.

One coordinated system
One accountable team for a complex energy brief.
Commercial heating and cooling projects need more than a single product. The heat source, distribution, controls, plant space, operating profile and installation programme all need to work together.
Thermal Earth can support the route from early feasibility and system design through installation, commissioning and ongoing service.

Commercial applications
Different sites need different system strategies.
Apartments and multi-residential
Assess central plant, communal and shared-loop approaches alongside distribution, resident control and the building brief.
Factories and Industrial
Review heating, cooling, temperatures, process loads, operating hours and the energy sources available around the site.
Offices
Coordinate heating, cooling, controls and comfort around occupancy, available plant space and the building's operating pattern.
Data centre cooling
Assess server loads, resilience requirements, temperatures and how rejected heat could be used elsewhere on the site.
Explore data centresHeat recovery systems
Bring otherwise-wasted heat and a useful demand together where their temperature and operating profiles align.
Explore heat recovery02System routes
A system strategy, not a single product
Select the heat source around the building and its loads.
Air source
A flexible route where outdoor-unit location, acoustics, temperatures and distribution design can be resolved.
Explore air sourceGround source
Use boreholes or horizontal collectors where the site, ground strategy and programme support the approach.
Explore ground sourceWater source
Consider available water sources, permissions and temperatures as part of a site-specific engineered design.
Explore water sourceCooling and heat recovery
Bring cooling and useful heat demands together where the building or process profile makes recovery practical.
Explore heat recoveryTechnology follows the brief. The appropriate route depends on loads, temperatures, operating hours, space, electrical capacity and the wider project constraints.
03From feasibility to aftercare
Understand the site
Review loads, temperatures, constraints, programme and the decisions already made.
Develop the design
Coordinate heat source, distribution, controls, plant and project information.
Install and commission
Plan and deliver the agreed works around the site and project programme.
Support operation
Provide handover, servicing and the agreed ongoing support after commissioning.
In-house capability
Coordinate design, groundworks and installation with one team.
Our system designers, borehole drilling crews and installation teams work together around the agreed project brief.
- System design
Develop the heat source, distribution, controls and plant strategy together.
- Ground-source delivery
Plan borehole or collector works alongside the site and programme.
- Commissioning and support
Complete handover and provide ongoing service options. Lifetime support available where selected.
04Project experience
Real Thermal Earth projects
View all success storiesDifferent buildings. Different sources. One engineering standard.
From apartment-scale communal heating to open-river cooling and the mine-water scheme developed with the Mining Remediation Authority, each system starts with the site and its loads.
Industrial & offices
Lindsay mine-water scheme
Wales's first commercial mine-water heat scheme was developed by the Mining Remediation Authority in partnership with Thermal Earth, with Innovate UK funding. It supplies heating and hot water to our industrial unit and offices.

Recognised standards behind the delivery team.
Thermal Earth holds recognised certifications, accreditations and memberships relevant to our work.
Procurement
Buy through a framework.
Thermal Earth is an approved supplier on the following procurement frameworks. Tell us which one your organisation uses and we'll confirm the call-off route for your scheme.
- CHIC — procurement frameworks for housing and public-sector asset management.
- pfH Cymru — Procurement for Housing frameworks for housing providers, including retrofit works.
- Procure Plus — procurement frameworks for housing works and low-carbon technologies.
Prequalification documents are available on request. Tell us what your buyer or funder needs so we can agree the evidence pack for your procurement.
Our credentials include MCS certified installer status, TrustMark, NICEIC/NAPIT, RECC and Heat Pump Association membership. Ask for current certification and membership evidence with your enquiry.

Status as of October 2026. Eligibility, deadlines and funding availability are set by each scheme; a heat-pump proposal does not guarantee an award.
| Route | Where and what | Current status |
|---|---|---|
| Public Sector Decarbonisation Scheme (PSDS) | England: grants for eligible public-sector building decarbonisation. | Closed to new applications. Existing Phase 4 awards are being delivered, with project deadlines set by the grant offer and no later than 31 March 2028. |
| Green Heat Network Fund (GHNF) | England and Wales: capital support for new low-carbon heat networks and expansion or decarbonisation of existing networks. | The published Round 12 deadline was 25 September 2026. Check the delivery partner for the next application window before planning a bid. |
| Ynni Cymru | Wales: smart local energy systems for eligible public, community and third-sector organisations and SMEs. Heat pumps can form part of an integrated project. | The 2026–27 capital grant round is closed to applications. Awarded projects must be completed by 31 March 2027. |
| Re:fit Cymru / RE:FIT 5 | Public-sector energy performance contracting, including Welsh projects. | A procurement and delivery route with contractual performance guarantees, rather than a grant. Ask Local Partnerships about the current framework and an appropriate financing route; this does not imply Thermal Earth is an appointed framework supplier. |
| Wales Funding Programme / Invest to Save | Wales: finance for eligible public-sector energy efficiency, low-carbon heating and renewable energy projects. | Applications are accepted. Salix lists 6 November 2026 as the deadline for 2026–27 applications on the published terms; later applications may be assessed on different terms. |
