We believe in providing a bespoke and unparalleled service, supporting your business and ensuring your environment runs smoothly, so you can focus on your day.


We are a leading provider of onsite resident and mobile, mechanical and electrical maintenance services.

Trusted by a diverse range of clients, across many business sectors, we deliver the highest quality support to critical operational facilities.

Whether it is a full time resident team that you require or a handyman to fix the jobs that you just don’t have the time for, our team always provides a skilled and professional service and this is reflected in the company’s growth and success. This is largely due to an absolute commitment to our clients. By taking the time to understand each customer’s unique requirements and business drivers and adopting an approach of partnership in everything we do, we tailor maintenance packages to suit each business’s individual and specific needs.

We provide both reactive and planned preventative maintenance services across a range of market sectors including banking and finance, industrial, commercial, pharmaceutical and retail.

Where the business has a high dependency on mission critical facilities and services, many of our clients enjoy the security of having a JCA resident engineering team permanently onsite.

The team are responsible for maintaining and overseeing a number of blue chip companies’ head offices in the City of London, West End and the South East. These include contracts held with landlords, clients and tenants.

By having qualified engineering professionals, familiar with all aspects of a site’s mechanical and electrical infrastructure and working practices, on hand at all times, the risk of system or facility down time is reduced and continuity of operation is maximised.

Our approach to resident sites is flexible and adaptable. We can meet the individual requirements of our clients because we understand they are unique in their business operations. We provide full time resident engineers, supported by our mobile engineering team, 24 hours a day, 7 days a week. Our resident engineering team are fully trained and regularly appraised to identify new training requirements and to ensure they are up to date with the latest legislation and industry regulations.

JCA’s mobile engineering service provides a cost effective way of maintaining a building’s mechanical and electrical services to the very highest standards.

We have the experience and resources to overcome the challenges of large property portfolio management, through our dedicated mobile services team. Whether it’s delivering basic maintenance contracts or as part of a comprehensive property service, we have multi-skilled technicians to support your special business needs.

The JCA Maintenance mobile engineering team have a detailed knowledge of building services, mechanical and electrical engineering, air conditioning and refrigeration. We successfully support the needs of our clients, across industry, from general building services to complex data centres. We consistently deliver a high quality 24/7 service and meet service level agreements (SLA’s) across our extensive contract portfolio.

JCA invest significantly in our mobile engineering team, with regular training to ensure up to date product and regulation knowledge is maintained. All JCA engineers are covered by Refcom Elite and the Air Conditioning and Refrigeration Industry Board (ACRIB) and have achieved the latest F Gas safe handling qualifications.

We also ensure that all our mobile engineers undertake comprehensive site familiarisation and induction as part of each contract mobilisation. By supplementing this familiarisation with our innovative onsite ‘grab pack’, our mobile engineering service delivers premium quality support when clients need it.

Whether a building is old or new, conventional in design or uses the latest energy saving systems, it is vitally important that it is maintained in good working order.

Inadequately maintained facilities result in increased energy bills and expensive repairs when things go wrong. Regular planned preventative maintenance ensures that equipment remains in sound operable condition. Not only does this minimise the potential for downtime in your business, it maximises the operational lifespan of your equipment and keeps your replacement costs down.

For every new contract we take on, we carry out asset verification and liaise with our client’s facilities team to review/create a planned preventative maintenance schedule. This enables our clients and our contractors to see, at a glance, the planned preventative maintenance that needs to be carried out.

In the event of an emergency situation, it is vital that you have confidence in your maintenance provider. The JCA team will respond to your issue quickly and effectively to ensure a positive resolution.

We appreciate the fundamental importance of responsiveness and we provide our clients with the assurance of a 24/7 help desk, staffed by a team committed to providing the highest levels of client care and attention. No matter what time you call, you can be confident that JCA will be there to support you. Our advanced help desk and transparent reporting of SLA adherence, means that our clients can always see our progress and performance.

At the heart of this operation is a state of the art customer service help desk. This is your link to efficient deployment of resource and fast problem resolution.

The help desk operates on a sophisticated works management system, coordinating all the planned and reactive activity involving thousands of visits every week. We are continually investing in our system capabilities to ensure maximum efficiency of operation and support for our clients.

JCA Maintenance offers the complete solution to all your property maintenance and repair needs. Our friendly and experienced team can take care of a variety of tasks; they will repair and fix all those jobs that you just don’t have the time or tools to complete.

From plumbing, electrical work, carpentry and decorating, our handyman team can deal with any job quickly and efficiently, ensuring the minimum disruption to your home or business.

Our team are insured, certified, and have been fully trained in workplace health and safety regulations.

Our clients trust JCA to manage the diverse range of specialist subcontractors for the maintenance of specialist plant and equipment. By managing subcontractors on behalf of our clients, we are able to provide a single point of contact to clients, backed up by consolidated and coherent reporting.

The principle of operating your sites and buildings under an integrated facilities management contract is simple – one point of contact, one invoice and a seamless delivery model for all your facilities services through one supplier. It makes sense; allows you to cut costs, streamline procedures, free up time and reduce administration effort.
