What we do
We provide electrical design and engineering, technical drawing, estimating, project management, and commercial and business support. Where installation is needed, it is delivered by our approved subcontractors under CMJ's management.
We work with contractors, developers and clients across residential, commercial and retail, hotel and leisure, education, healthcare and data centre projects, on electrical packages of all sizes.
Alongside project work, we provide business and document control support for growing businesses, from policies and procedures to tender submissions, and we're building a range of digital products: editable templates, packs and forms for contractors and building owners.
We support projects from initial concept and design through procurement, installation, commissioning and completion, or provide targeted support at any stage.
How we work
You get experienced, senior involvement from enquiry to handover, with clear accountability, regular updates and quick decisions.
We share project documents through dedicated Microsoft 365 project folders, or work within your own document management platform.

Our core values
- 01
Quality
Right first time, to standard.
In practice: We check every design, report and product against BS 7671, the relevant standards and the brief, peer review our work before it is issued, and close out snags.
- 02
Integrity
Honest advice, even when it is unwelcome.
In practice: We raise risk, cost and programme issues early, give our clients the facts, and never oversell what we can deliver.
- 03
Safety
Nobody is harmed because of our work.
In practice: We design out risk under CDM 2015, follow safe isolation procedures and RAMS, and stop work when something is not right.
- 04
Ownership
We do what we say, when we said, and see every job through.
In practice: One point of contact from start to finish, programme dates met, quick responses, and problems solved rather than passed on.
- 05
Partnership
We work as part of our client's team.
In practice: We build long-term relationships, solve problems together with our clients, and share what we know with the wider industry.
