WHAT WE DO

From concept to commissioning.

From concept to commissioning.

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.

FAQ

FAQ

Common questions.

Common questions.

Common questions.

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.
