Services

Every service in the building, one team accountable.

Consultation, design, fit-out and commissioning across mechanical, electrical and renewable systems. Take one stage, or let our teams deliver the whole turnkey package.

Disciplines

Mechanical. Electrical. Renewable.

Each discipline is strong on its own. Together, they let us integrate new technology with existing infrastructure, improve efficiency and reduce environmental impact.

Mechanical

Heating, ventilation, plumbing and process services, designed around how a building is actually used.

  • HVAC and comfort cooling
  • Ventilation and extract, including ATEX-rated systems
  • Central heating and gas boilers
  • Plumbing, hot water and sanitaryware
  • Process pipework and instrumentation
  • Planned and reactive maintenance

Electrical

From LV switchboards and isolated supplies for clean rooms to full rewires across occupied housing estates.

  • LV distribution, switchboards and sub-mains
  • Lighting and DALI lighting control
  • Emergency lighting and fire detection
  • Data, fibre and UPS systems
  • Earthing, bonding and lightning protection
  • Access control, CCTV and intruder alarms

Renewables

Solar PV, battery storage and EV charging, connected properly to the systems that are already there.

  • Commercial and domestic solar PV
  • Tesla Powerwall battery storage
  • EV charge points (OZEV approved)
  • DNO applications and grid connection
  • Inverters, optimisers and monitoring
  • Ongoing maintenance and support

Project stages

Four stages. Individually or turnkey.

01 / 04

Consultation

Every project starts with a conversation about the problem, not the product.

We look closely at the issues you are facing now, then work towards a solution that fixes them and runs more efficiently than before.

Our engineers know the demands of the sectors we work in, but we have learned that the best results come from collaboration. Consultation is where that relationship starts.

  • Site survey and existing-services review
  • Load, compliance and risk assessment
  • Budget and programme planning

Design

Mechanical, electrical and renewable designs that work hard, look right and pass audit.

Many of our builds are for sectors where health and safety, hygiene, manufacturing and electrical specifications are audited. Every design meets those requirements and specifies components chosen to last.

Whether it is a field of solar panels or a full MER package for a hospital ward, a specialist designer leads the work and liaises directly with your contractors.

  • Full M&E and renewable design packages
  • Regulation-led specification
  • Direct coordination with main contractors

Fit-Out

Installation is what turns a good building into a space that works.

We install every component to the manufacturer's guidance, and we source specialist equipment where a project needs it.

Our installation teams run strict quality checks as they go, so the final details are finished to the same standard as the rest of the build.

  • Installation to manufacturer guidance
  • Specialist equipment sourcing
  • Staged quality inspections

Commissioning

Handover happens when everything is proven, not before.

Our commissioning engineers are qualified to verify performance across a wide range of systems, from light fittings and fire regulations to specialised medical equipment.

Everything is tested and certified as fit for use, and accreditations are passed on before handover. Our support team stays available after completion.

  • Testing, inspection and certification
  • Full documentation at handover
  • Post-project support

Questions

Why Thomas Halliwell?

Can't see your question? Call us on +44 (0)161 652 8022.

What does “MER” mean?

Mechanical, Electrical and Renewables. We started as M&E contractors and grew our renewable expertise to the point where it became a core service. Because we understand the building services already in place, we can integrate solar, storage and EV charging with existing infrastructure, improve efficiency and reduce environmental impact.

What principles do you work to?

Accountability, careful project management, reliability and uncompromising quality. We bring the same commitment to the smallest refurbishment as to the largest new installation.

Which industries do you work in?

A very wide range, from power generation and renewables to social housing, healthcare, food production, pharmaceuticals and copper smelting. The more niche or bespoke the project, the more value we add.

Are your engineers accredited?

Yes. We are NICEIC approved and Gas Safe registered, and we work to all relevant British Standards and electrical safety regulations. We are also MCS certified, OZEV approved, ECA registered and ISO 14001 certified.

Do you work as main contractor or sub-contractor?

Both. We deliver turnkey packages directly for clients, act as principal contractor on complex projects, and work as M&E sub-contractor to main contractors including Mace, Bouygues, Vinci Facilities and Forrest.

Do you offer maintenance contracts?

Yes. We hold hundreds of maintenance contracts nationwide, with 24/7 rapid-response cover for commercial and industrial clients and annual packages for residential customers.
