Over a Decade of Engineering Integrity & Standards

1. The Foundation of Our Scottish Engineering Practice

TES ELECTRICAL & MECHANICAL LIMITED was established on 15 April 2013 by founding director Ais Ais with a singular commitment: to deliver rigorous, uncompromising electrical installation engineering and mechanical building services in strict accordance with British Standards. Headquartered at 5 Hornock Road in Coatbridge, Scotland, the company grew from a specialized electrical contractor into a widely consulted engineering knowledge base and technical advisory practice.

Coatbridge has historically served as a powerhouse of Scottish industrial innovation and manufacturing. Carrying this proud industrial heritage forward into modern infrastructure, TES ELECTRICAL & MECHANICAL LIMITED bridges the vital gap between hands-on engineering execution and complex statutory compliance.

2. Chronological Milestones: 2013 to Present

Over more than 13 years of continuous operational activity, our technical practice has evolved through key industry transitions:

• April 2013 – Incorporation in Scotland: Registered under Companies House Scotland (SC447561) at 5 Hornock Road, Coatbridge, providing commercial electrical installations and industrial power distribution setups.
• 2016 – Mechanical & HVAC Integration: Expanded technical advisory capabilities to encompass combined electrical and mechanical building services, including air handling units (AHU), chiller controls, and building management systems (BMS).
• 2018 – Transition to BS 7671 18th Edition: Led educational workshops and compliance auditing for commercial facilities transitioning to the 18th Edition of the IET Wiring Regulations.
• 2022 – Renewable Interconnection & EV Infrastructure: Published specialized design guidance on earthing arrangements (TN-C-S vs TT) for electric vehicle charging infrastructure and commercial photovoltaic arrays under BS 7671 Amendment 2.
• 2026 – Open Technical Intelligence Portal: Launched this digital engineering portal, making peer-reviewed engineering calculation tools, voltage drop algorithms, and BS 7671 inspection checklists openly accessible to industry professionals.

3. Core Engineering Governance & Standards

At TES ELECTRICAL & MECHANICAL LIMITED, our technical publications and engineering consultancies are anchored in the following regulatory frameworks:

• BS 7671 (IET Wiring Regulations): Adhering to the latest requirements for electrical installations, earthing arrangements, disconnection times, and arc fault detection.
• Electricity at Work Regulations 1989 (EAWR): Ensuring all design criteria prevent danger from electric shock, burn injuries, fire, and explosions in industrial workplaces.
• BS EN 61439: Low-voltage switchgear and controlgear assembly verification, Form 4 internal separation standards, and short-circuit withstand ratings.
• UK Building Regulations: Enforcing Part P (electrical safety in dwellings) and Part L (conservation of fuel and power) across mechanical building services.

4. Leadership Statement from Director Ais Ais

“When we founded TES ELECTRICAL & MECHANICAL LIMITED in Coatbridge back in April 2013, our primary objective was unwavering technical precision. Electrical and mechanical engineering does not forgive shortcuts. Whether designing a main distribution switchboard or publishing guidance on harmonic mitigation, our team approaches every task with rigorous scientific discipline, complete regulatory adherence, and deep accountability to the public and industrial community we serve.”

– Ais Ais, Director, TES ELECTRICAL & MECHANICAL LIMITED

5. Quality Assurance & Health and Safety Commitment

Health, safety, and environmental stewardship form the cornerstone of every recommendation on this portal. We endorse zero-harm working methodologies, rigorous Lockout/Tagout (LOTO) procedures, and comprehensive pre-commissioning dead testing regimes.

Furthermore, we advocate for circular economy practices in industrial electrical installations, promoting the responsible recycling of copper busbars, low-smoke zero-halogen (LSZH) cabling materials, and high-efficiency transformers that minimize operational lifecycle losses.
