WHAT WE DO
We provide independent M&E design and consultancy support at every stage — from initial heat calculation and feasibility assessment, through to fully detailed system design and commissioning. Our portfolio spans more than 150 completed GSHP, ASHP, WSHP and multi-technology installations, including several award-winning and district heat projects.
We work as an extension of your team, offering rigorous, independent technical insight without the overhead of a traditional building services practice.
SERVICES
Full System Design
Feasibility, concept design and fully detailed M&E design — heat calculations, schematics and plantroom layouts through every RIBA stage.
Hydraulic Modelling & Simulation
Modelling, validation and optimisation, in partnership with Twelvetrees Digital Buildings Ltd.
Heat Networks
District and communal heat network design — network hydraulics, plant sizing, metering strategy and low-carbon heat sources.
Installation & Project Management
Hands-on through delivery: contractor coordination, clerk-of-works oversight, tender oversight and commissioning management on site.

TESTIMONIALS
What our clients say.
What types of project do you undertake?
All mechanical & electrical design — heat networks, plant rooms, building services and full system design — from client-side design management to specific outputs that bridge a gap in an existing project.
Can you work alongside our existing consultants or engineers?
Yes — we’re often brought in to provide client-side design management, or to deliver specific outputs that bridge a gap in an existing project, working alongside your team rather than replacing it.
How long does a typical project take?
It depends on scope and complexity — a straightforward feasibility study can turn around in days, a full system design across multiple RIBA stages takes longer. Get in touch and we can give you a realistic estimate for your project.
How do you keep us updated during a project?
You’ll have a direct line to the engineer working on your project, not a call centre — we provide updates at agreed milestones and are reachable by phone or email in between.
What are the costs?
We price on a project-by-project basis, as no two are the same. Get in touch to discuss yours.
Are you fully insured?
Yes — we hold full professional indemnity design insurance.
