Our team of expert mechanical engineers and experienced project managers work together to deliver complex projects incorporating air and water heating, ventilation, air conditioning and building management systems which minimise running costs and reduce maintenance spending.
Efficient heating, ventilation and air conditioning systems are a critical part of maintaining a safe and comfortable working or living environment. Well-designed systems allow you to make precise adjustments to temperature and air quality while controlling overall energy spending.
We have extensive experience in designing, fitting and maintaining HVAC systems at any scale, from domestic or small-scale commercial properties to high-volume implementations for warehouses and manufacturing plants, to specialised systems for healthcare or scientific applications.
Ensuring the safety and consistent operation of hot and cold water supply is critical for all types of property, from residential to industrial. Plumbing systems require careful design and regular servicing to ensure that they can deliver the required load without the risk of leaks or failure.
Our fully certified engineering team can design, supply, install and maintain integrated plumbing systems at any scale, including capacity and pressure analysis, routing of hot and cold water pipework, and installing heaters, chillers, pumps, filters and demineralisation systems.
Building Management Systems (BMS) or Building Automation and Control Systems (BACS) are used to monitor, manage and control subsystems within a building including electrical, HVAC, gas, water, fire safety and security. They provide a single point of access for building managers, maintenance/incident alerts, and event logging.
JLM offers BMS integration as part of our engineering services — either configured and installed as we implement new infrastructure or retrofitted to manage existing systems more efficiently — helping our clients to reduce their energy consumption and increase standards of safety and security.
From multiple occupancy dwellings to commercial and industrial applications, boilers and boiler plant rooms are a fundamental necessity — and it’s vital that the system and components are correctly designed and configured to ensure safe and consistent operation.
We work with clients across all sectors to deliver permanent or mobile/temporary boiler and plant solutions which are tailored to planned usage levels and make the best use of available space to deliver hot, low-temperature hot or cold water for a range of applications.
Our fully qualified and Gas Safe registered engineers provide a range of domestic, commercial and industrial gas installation services, on an individual basis or as part of larger projects, as well as offering maintenance, repair and breakdown/emergency cover for new or existing clients.
From project planning and design through to installation and testing, JLM specialises in large-scale heating systems, commercial gas boilers, gas system surveys and audits, meter and regulator assessments, gas leak detection, re-piping, gas turbines and commercial kitchen gas appliances.
Above-ground drainage systems channel wastewater from building exteriors and interiors to the main sewer system. Components include downpipes, sunken channels and guttering to manage rainwater, as well as soil & waste systems to safely transfer greywater and blackwater to the sewer.
JLM will work with you to design the most cost-effective and low-maintenance above-ground drainage system that meets the outflow capacity requirements of your property, and we can incorporate water-saving elements such as water recapture and storage if required.
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.
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.
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.
JLM has worked under contract as an approved supplier to Amazon UK Services to provide a wide range of mechanical and electrical engineering services as part of multiple individual projects across a number of Amazon locations sited throughout the UK, from Scotland to London.Learn More
