Geothermal industry partner support
Your client asked for geothermal and TownRock Energy is the part you subcontract. You keep the client, the fee and the project management. We take the subsurface and hand back a section that drops straight into your report, whether you are an M&E practice, an architect, a masterplanner, a contractor or a building services supplier.

Where the line sits
The boundary matters more than the brochure, so here is ours in writing.
- You can keep the client relationship and all client-facing communication
- You can keep project management and the lead consultant role
- You can keep the demand-side calculations and the overarching financial model
- We’ll handle the subsurface, covering geology, resource, modelling and borehole design
- We’ll handle the geothermal plant-room equipment and its capex and opex
- We’ll handle permitting and consent routes for the subsurface works
Behind that boundary sits a multidisciplinary team of engineers, geoscientists and project managers led by subsurface and engineering directors with more than 100 years of combined experience.
What lands on your desk
A section, not a separate report
Written to sit inside the main body of your feasibility study, or as an annex to it, whichever suits your document.
Inputs your model can take
Capex, opex, output profiles and performance assumptions structured to drop into your financial model.
Something you understand
On most projects we never meet your client. We brief you properly so you can carry the subsurface argument yourself.
Work delivered inside someone else’s project

Mine water assessment inside a district energy study
One clearly bounded workstream inside a much larger feasibility study led by others, assessing flooded mines as a low-grade heat source, a thermal store, or both.

Ambient loop options appraisal
The M&E consultancy leading the project brought us in to appraise ground-side options for an ambient loop network. They kept the client and the services design; we answered the subsurface question.

Mine water heat options for a heritage site
A mine water options appraisal and survey delivered for the M&E consultants and architects on a museum decarbonisation project, scoped tightly to the ground-side question.
We work to RIBA stages
Stages 0 to 1
Screening & options appraisal
Is there a resource, could it meet the brief, how does it compare? Priced for an early-stage fee.
Stages 2 to 3
Concept design & cost
Borehole array layout, site footprint, plant room implications, capex and opex.
Stage 4
Detailed design & permitting
Subsurface modelling, well design, surface plant, permit applications.
Stages 5 to 6
Drilling & commissioning
Site geologist and engineer through drilling, testing and commissioning support, and verification of third-party operators against contract on your client’s behalf.
