Hayman Mechanical Services Limited

Hayman Mechanical Services is a trusted mechanical and electrical contractor based in Wigan, Greater Manchester. We provide a comprehensive range of engineering services, including project delivery, asset servicing, planned and reactive maintenance, and renewable energy installations. With decades of experience and a strong technical foundation, we have established ourselves as a reliable partner for clients requiring efficient and accountable engineering support.

Our business model is centred on in-house delivery. By employing our own engineers, project managers, and support staff, we retain full control of quality, programme, and safety on every project. Subcontractors are used only where specialist input is essential, ensuring that responsibility always remains with Hayman. This approach reduces risk, improves communication, and provides clients with confidence that all works will be delivered to the highest standard.

The core services we provide include:

Mechanical Services – installation, replacement, and maintenance of heating, ventilation, and plumbing systems.

Electrical Services – full electrical installations, upgrades, testing, and compliance.

Maintenance – planned and reactive servicing of mechanical and electrical assets, supporting compliance and minimising downtime.

Renewables – design and installation of sustainable technologies, including solar PV, air source heat pumps, and LED lighting systems.

We understand that our clients’ assets are critical to the safe and efficient operation of their buildings. For this reason, we place equal importance on maintaining existing systems as we do on installing new ones. Our maintenance programmes are designed to ensure compliance with current regulations, extend equipment life, and reduce costly interruptions to daily operations.

Recent projects highlight our ability to deliver integrated solutions across our service areas. Examples include large-scale mechanical replacements, building-wide electrical upgrades, and renewable installations designed to reduce energy consumption and carbon emissions. These projects have been completed efficiently by our own teams, supported by a structured management system accredited to ISO 9001, ISO 14001, and ISO 45001. These certifications reflect our commitment to quality management, environmental responsibility, and health and safety across all aspects of our work.

By combining project delivery with ongoing servicing and renewable technologies, Hayman Mechanical Services provides a complete package that meets both current operational needs and future sustainability objectives.
