Speak To Us About Your Project

Expert Building Services

Building services are the systems that make a building safe, efficient, and comfortable — the engineering that brings every space to life. They encompass all the mechanical, electrical, and public health (MEP) systems that ensure buildings function effectively, sustainably, and in full compliance with UK regulations.

From power and lighting to heating, ventilation, controls, and renewable energy, building services engineering is central to the performance and sustainability of any modern building.

At the Evans Group, we design, install, test, and maintain complete M&E systems. Our expertise covers the commercial, industrial, education, healthcare, accommodation, retail and leisure sectors, delivering reliable, efficient, and safe environments that meet today’s energy and performance standards.

Integrated M&E and Specialist Systems

The Evans Group offers a coordinated approach to M&E delivery — ensuring all services operate harmoniously for performance, safety, and energy efficiency. Our integrated works include:

  • Isolations and strip-out works
  • Testing and commissioning, including client demonstrations and witnessed testing
  • Comprehensive O&M manuals, complete with working and as-fitted drawings
  • Building logbooks for compliance and lifecycle management
  • Maintenance packages for long-term reliability and compliance
  • Vertical transportation systems, such as lifts and platform lifts (in partnership with specialist installers)
  • Firefighting systems – dry risers, hydrants, and extinguishing systems
  • Energy monitoring and sustainability reporting

Supporting Sustainable, Efficient Buildings

The Evans Group is committed to advancing sustainability through modern building services design and delivery. From low-carbon heating and renewable power generation to smart controls, EV charging, and energy-efficient lighting, we help clients reduce carbon footprints, improve operational performance, and achieve compliance with the latest standards — including Part L of the Building Regulations, CIBSE guidance, and BS 7671 (IET Wiring Regulations).

Our Process

Each building services engineering project is delivered through our structured 8-stage service model:

  1. Design

M&E design, load-analysis, lighting design, energy-efficient solutions, resilience planning and technical coordination.
We work collaboratively with contractors, consultants and developers to ensure deliverability, risk management and cost control.

  1. Supply

We take responsibility for procuring all equipment, materials, wiring, containment and control systems — ensuring specification compliance, quality assurance and value for money.

  1. Installation

Our experienced engineers carry out safe and efficient installation of all electrical systems on-site. With more than 100 skilled engineers, we handle installations of every size and complexity.

  1. Commissioning

Functional checks, system integration, programming, load testing and performance validation — we ensure your M&E installation is fully operational and compliant.

  1. Testing

From LV/HV switchgear certification to emergency lighting tests and thorough system verification, we provide full testing services and documentation as part of the electrical installation.

  1. Maintenance

Once installed, we support long-term asset performance via planned preventative maintenance (PPM), reactive maintenance, condition reports and lifecycle management. Our service helps clients protect their investments.

  1. Strip Out

When systems reach end-of-life, require replacement or where refurbishment is planned, we provide safe and environmentally-responsible removal of redundant installations as part of the broader mechanical and electrical installation lifecycle.

  1. Safe Isolation

Strict safe-isolation procedures are front-of-mind for all our installation work — to protect people, property and ensure regulatory compliance during upgrades, maintenance and refurbishment.
