MV Electrical is a UK mechanical and electrical contractor: solar PV, EV charging, commercial fit-out, BS 7671 compliance, across London and the Home Counties. Multi-million turnover, a lean team, owner still close to the work. Growth was throttled not by demand but by the admin tail behind every job. Here is what we rebuilt, and what changed.
Before the rebuild, the familiar trade-firm pattern. Project-management tools that each handle one workflow but never fit the shape of a real construction job, where multiple sites, multiple suppliers and multiple jobs all move at once. A patchwork between those tools and the supplier portals everyone has to use (MCS, DNO, warranty registrations, accreditation systems). And the quiet tax of stale knowledge: tools touched once a fortnight, so every return started with ten minutes of remembering how it worked.
The symptoms were the ones every owner-operator knows. Tenders going out at 2am. Saturdays in the office to keep things moving. O&M manuals taking a week of office time and still coming out nowhere near as polished as they should be.
Over months, working first as a consultant and now embedded as Head of Digital Operations, the operations layer was rewired across the surfaces below. We do not replace the supplier portals. MCS, DNO and warranty registrations stay external; AI helps the firm navigate them faster. What we replaced was the project-management patchwork, and we bridged the messy reality of a live job into the documents that have to leave the building.
| Layer | Before | After |
|---|---|---|
| Solar PV pipeline | The same data re-entered across DNO submissions, MCS registrations, warranty registrations and handover packs. One missing document could hold up grid connection by weeks. | Data lands once, at proposal stage and on the on-site capture. The downstream documents generate from those two sources. The admin tail of human work drops from weeks to days. |
| Project documentation | Project data spread across boards, Drive folders, email threads and WhatsApp screenshots. No single place where the job actually lived. | One workspace where the data, templates and AI tooling sit together. The same data flows into costing, customer records, payment applications and certificates without being re-typed. |
| O&M manuals | A week of office time per manual. Eighty-plus pages assembled by hand, and still not as polished as they should be. | The email thread, the spec, the call transcripts and the folder paths feed the system. The manual evolves across the job, every substitution and scope change reflected. Human work: a day or two of review, spread thin. |
| Quality-assurance packs | Setting up an in-site form per project took days. Engineers struggled with it on the ground. Exports took days more. Output did not match the firm's brand. | A form on site that is AI-authored for the specific job and pre-filled, so the engineer reviews and confirms rather than fills from scratch. Bulk corrections handled across plots. Output in the firm's brand. |
| Payment applications and variations | Hand-drafted at month-end across multiple jobs. Variations slipping through unbilled. Applications going out at 11pm on the last Friday. | Drafted from the live job data each month. Variations caught and evidenced, not lost to next quarter. Applications in on time, in full. |
| Document retrieval | Hundreds of files scattered across folders. "What was the model number on that boiler at the school in 2023?" cost twenty minutes of hunting. | Every file indexed with description, type and tags. A twenty-minute hunt becomes a sentence to the system and a couple of minutes to read the answer. |
The reconciliation is the sequence. The first thing we do is organise the chaos. After that, every downstream task gets exponentially easier. That is why this took months rather than weeks, and also why it did not take years.
The misconception we meet most often: "we need to clean our data before we can use AI." No. AI does the cleaning. What you need is an operator willing to sit inside the business while it happens. Drafts go to a single approver, and nothing leaves the building autonomously.
Most M&E firms of this size keep a Quality Management System because the accreditor (NICEIC, NAPIT, ISO) requires one. It is built for compliance audits, not for running the business day to day. The folders get updated when an inspection looms; the rest of the year they go stale.
What we do is not a parallel system. It is the engine that keeps the QMS structures populated as the work happens. The accreditor sees a system that is current; the firm gets the operations layer the QMS template implies but never delivers on its own. The framework you already pay to maintain starts paying you back.
Thirty minutes, direct. We ask about the business; you decide if we're the people for the job. No deck.
