He leads our contracts, tenders, pricing and customer relationships, and is the final point of escalation on every contract. He holds FIA qualifications in fire detection and emergency lighting, FETA extinguisher training and the 18th Edition wiring regulations.
Len Mason

He oversees day-to-day operations, capacity planning and the IT and job-management systems that schedule our engineers and record every visit. Like Will, he holds FIA qualifications in fire detection and emergency lighting and FETA extinguisher training.
Abhi Patel
Contracts and Maintenance Manager. With more than 15 years at Fire Systems, Abhi is the single point of contact on our maintenance contracts. He manages performance against KPIs, compliance, scheduling and our emergency response, and leads the mobilisation of new contracts. He is a certified Project Management Professional with a Lean Six Sigma Green Belt and the SMSTS site safety qualification.
Dax Patel

Vipul Arora
Store Operations and Purchasing Manager. Vipul runs our stores and purchasing, keeping the right fire alarm, emergency lighting and AOV parts in stock. He manages supplier pricing, tracks how materials are used and organises the stock our engineers carry in their vans, so the parts they need most are already to hand when they arrive on site.
Thurston Selvakumar

He supervises our remedial works and is the main point of contact for residents, explaining the work, arranging access and making sure vulnerable residents are given the support they need.

John Slade
Health and Safety Consultant. John is our health and safety consultant and brings more than 20 years of health and safety experience. He prepares and reviews our risk assessments and method statements, runs our health and safety audit programme, and supports incident reporting, CDM 2015 compliance and our SafeContractor accreditation.
Jenish Patel
Commercial Service Manager. Jenish has been with Fire Systems for around 14 years and is often the first person new customers speak to. He handles enquiries for fire alarm installations, servicing, fire extinguishers and fire risk assessments, prepares quotations and stays with each customer through to completion.
We combine the personal service of a family business with the experience, infrastructure and technical capabilities to deliver complex, large-scale fire protection contracts.

Our journey
1992 · Where it began
Brothers Len and Will Mason begin their careers as fire alarm engineers with Modern Alarms, learning the trade on site and building the technical foundations the business still relies on today.
1994 · Subcontracting
Len and Will move into subcontracting, working on a wide range of systems and sites and building practical experience and lasting relationships across the fire protection industry.
1996 · Freelance Fire Ltd
They establish Freelance Fire Ltd to supply skilled engineers to larger fire protection companies. That work shows them how many customers want more personal attention, responsiveness and reliability.

Len and Will acquire Fire Systems Ltd and begin working directly with customers, combining technical expertise with responsive, personal service and clear accountability from people customers know and trust.
2005–2006 · Electronic records
We invest in a job-management system and handheld devices for our engineers, moving our records to electronic reporting and giving customers clearer maintenance histories and visibility of defects.

We develop specialist expertise in wireless fire alarm systems, giving customers a practical option for occupied buildings where installation needs to cause as little disruption as possible.

We look after everything from single commercial premises to extensive housing portfolios, still led by Len and Will and supported by an established management team and directly employed engineers.
