Electrical services.

JLM’s highly-skilled electrical engineers specialise in industrial and commercial lighting systems, mains and sub-mains distribution and specialist earthing solutions for large-scale implementations, as well as offering a full range of small power services for residential or smaller-scale commercial clients.

Minimising running costs and reducing maintenance spending.

Select service


Ensuring adequate and reliable lighting is in place is an important factor in the safety and security of your working environment, preventing workplace incidents as well as ensuring healthy living and working conditions for residents or employees. 

We’ll develop and implement a lighting plan for your premises incorporating external and internal lighting as well as emergency lighting. Where appropriate we recommend low-power LED lighting to keep running and replacement costs low, and reduce the amount of maintenance required.

High Voltage Distribution & Substations

JLM is qualified and experienced in providing HV solutions, from large-scale industrial plant systems to smaller commercial installations. We’ll work with you to develop a detailed project plan taking into account local network constraints and site-specific limitations, and handle installation, testing and regular service inspections.

Our engineers are qualified to work with high-voltage systems up to and including 33 kV. Projects include plant installation, substation design, construction and management, as well as cable lay, overhead lines, power distribution and earthing.

Low Voltage Distribution

We design low-voltage power supply and distribution plans for new developments or refurbishment/upgrades to existing premises and provide an end-to-end service combining project management, component supply, installation, inspection and testing and ongoing maintenance and servicing. 

Our low-voltage distribution services include the supply, installation and maintenance of circuit breakers, busses, enclosures, panel boards, protection relays and switchboards, as well as integrated management software to monitor and control power systems centrally.

Earthing Specialists

A well-designed and functionally effective earthing service is a critical factor in ensuring site safety, reliability and consistency of power supply. Our expert electrical engineers use the latest software and testing tools to design a system that meets your usage needs and complies fully with relevant BS standards.

From soil resistivity surveys and earth resistance measurements to the inspection and testing of existing systems, and the design and commissioning of new systems, we offer an end-to-end service to ensure the safety of your premises and your employees. 

Small Power

As well as large-scale electrical installations, we also have expertise in more limited-scope projects including domestic and small-scale commercial electrical solutions. We apply the same rigorous standards and attention to detail as in our more extensive projects, and the same personalised service to ensure your needs are met precisely.

Get in touch for more information on additional sockets or circuits, extra data points, relocation or replacement of lighting, small-scale solar PV or heat pumps, or any other project which requires a reliable, qualified and customer-focused electrical engineer.

Lightning / Surge Protection

According to BS7671, surge protection devices are required for the majority of commercial and industrial applications and are recommended in many residential developments to prevent the risk of fire, equipment damage, or injury in the event of over-voltage caused by grid fluctuations or lightning strikes.

JLM can design and implement surge protection and lightning protection systems to suit the particular needs of your installation, including selection of the appropriate Surge Protection Devices SPDs for each input, panel, or distribution board, as well as testing and scheduled servicing and maintenance.

Electric Vehicle Charging

With almost a million hybrid and electric cars on the road in the UK, and as many as 10 million expected by 2030, providing secure and reliable charging points for fleet, visitor, employee or contractor vehicles is an increasing priority for businesses across all sectors.

We’ll manage the whole process from end-to-end, including requirements analysis and sourcing of the correct charging equipment and infrastructure, including pay-per-charge terminals if required, to installation and testing, along with ongoing maintenance.

Solution Design

Our designers will work closely with your team to capture requirements, assess risks and agree on budgets and time constraints. Working from your existing plans or conducting on-site visits we’ll then deliver a comprehensive project design for your approval. 

We don’t have exclusive partnerships with any one manufacturer or distributor, so you can be sure our designers are focused solely on delivering the most efficient and cost-effective solution for your needs.

Project Management

As a full-service engineering firm, we’re experienced in managing infrastructure projects across a wide range of industries and at any scale. We offer a comprehensive project management service to alleviate the pressure on our clients' in-house teams during project delivery.

From the initial briefing, through the design stage and on to installation and ongoing support, you’ll be assisted by a dedicated project manager who will coordinate suppliers, inspections, testing, compliance, health and safety and more — leaving you to focus on running your business.

Lightning / Surge Protection

Regularly scheduled testing, servicing and maintenance are crucial to prolonging the life of your infrastructure and equipment — and protecting your investment. We offer comprehensive preventative maintenance packages that fit around your workflows to minimise downtime or interruptions. 

For emergency or short-notice scenarios, JLM has engineers on standby to attend callouts across the UK on a 24-hour basis, fully qualified to address any electrical or mechanical issues and get you back up and running as quickly as possible.
