LifeEngineered.
MAC. is an Aberdeen electrical engineering firm working across domestic, commercial, industrial and agricultural sites — from clean sheet design and installation through to fault finding, power quality, automation and the data networks everything else depends on.
01 — Capabilities
Eight disciplines.
One contractor.
Design, installation and diagnosis under one roof — so the engineer who calculated the load is the one who signs off the certificate.
Electrical Design
Full electrical design from a blank page — load schedules, single-line diagrams and documentation detailed enough to build from.
Installation
Domestic, commercial, industrial and agricultural installation work — neatly executed, tested and certified on completion.
Fault Finding
Systematic diagnosis of intermittent trips, nuisance faults and equipment failures — with the root cause written down, not guessed.
Power Quality Analysis
Harmonics, transients, voltage dips and unbalance measured properly, so equipment failures stop repeating.
Automation
Smart home, building automation and industrial process control — programmed, commissioned and documented for the people who run them.
UPS / BESS / Renewables
Resilient power and on-site generation — UPS systems, battery storage, solar and EV charging designed around real load profiles.
Data, Networks & CCTV
Structured cabling, wireless and fibre — from a single cabinet to point-to-point wireless links and full site networks.
Security & Fire
Intruder detection, access control and fire detection systems — installed to standard and maintained for their working life.
02 — How we work
Engineering that holds up after handover
Most electrical problems are decided long before anything is terminated. We work from the design outwards, so the finished system is documented, maintainable and safe for whoever inherits it.
Designed before it is installed
Load calculations, diagrams and schedules come first. Nothing is made up on the day, and nothing is discovered after the wall is closed.
One standard, four sectors
A domestic rewire and an industrial panel get the same discipline: tested, labelled and certified, with a handover pack you can actually use.
Diagnosis, not replacement
Fault finding is measurement and evidence — insulation, thermography, logging — with the root cause written down before a fix is quoted.
4
Sectors served
Domestic, commercial, industrial and agricultural — one engineering standard across all of them.
8
Disciplines
Design, installation, diagnostics, power quality, automation, energy storage, networks, security.
1
Point of contact
The engineer who designs the system is the one who commissions it.
03 — Projects
Recent work
Grain store supply & controls
Aberdeenshire · 2024
Three-phase supply, drying controls and standby resilience for a working grain store — designed around a harvest window that does not move.
Read case studyProcess line re-control
Aberdeenshire · 2025
Legacy relay logic replaced with a PLC and HMI package, re-commissioned in phases so production could keep running between changeovers.
Read case studyLV distribution upgrade
Aberdeen city centre · 2025
A dated distribution system replaced with a fully documented LV installation sized for the building's next decade — delivered over staged weekend shutdowns with the floor open every Monday.
Read case study04 — Process
From first survey to final certificate
Brief
A site visit and an honest conversation about what the building or process actually needs.
Design
Loads, diagrams, schedules and specifications — everything resolved before a tool comes out.
Install
Neatly executed work, staged around your operation rather than through it.
Commission
Tested, labelled, certified and demonstrated to the people who will run it.
Support
Documentation handed over, and a number that reaches the engineer who did the work.
05 — Insights
From the logbook
Why nuisance tripping is never random
A breaker that trips once a week is telling you something specific. Here is how we find out what, before anything gets replaced.
Power quality: what it actually means on site
Harmonics, transients and voltage dips get blamed for everything from failed drives to hot neutrals. Here is what each one really tells you.
Designing a board someone can maintain
A distribution board is a document as much as it is hardware. The difference shows up five years later, at 2am, in the dark.
