The Story

Who They Are — LDN Security Solutions

Based in London, LDN Security Solutions provides professional security system design, installation, and maintenance services across the UK. The company began with just three employees and a clear mission—to deliver reliable, efficient security solutions for residential and commercial clients.

Today, with a team of 10 and turnover of £1.6 million, LDN Security Solutions has grown into a trusted partner in the security space, with Simpro powering its operations behind the scenes.

The Challenge — Manual Workflows and Growing Pains

In the early days, John Line, co-founder of LDN Security Solutions, managed operations using a patchwork of Word documents, spreadsheets, and folders. While organised, this system was inefficient, hard to train others on, and not scalable.

Line knew he needed a better solution. When a colleague recommended Simpro, he arranged a demo. Despite the upfront investment, the value was clear. “I really liked it,” he recalls. “It was a massive commitment at the time, but I knew it was the right move.”

The Solution — Training, Adoption, and Centralised Control

Line invested in 25 hours of one-to-one training with Simpro and began reshaping the business around the software. “Every challenge we faced, we asked—how do we do this through Simpro?” he says. “We adjusted our processes to fit the system, and it paid off.”

Simpro quickly became the central hub of operations. From quoting to asset management, everything now runs through the platform. With six years of records stored, the team can instantly retrieve a complete history of any job or customer.

The scalability was also a key benefit. “We’re at £1.6 million now, but I’ve seen companies running £20 million through Simpro,” says Line. “It’s more than capable of growing with us.”

The Impact — Growth Through Efficiency

Simpro has enabled LDN Security Solutions to scale without chaos. Admin time is down, training new staff is easier, and processes are standardised across the team.

The transition wasn’t without its challenges. Getting engineers to adopt the system fully took time. Line listened to their feedback and simplified how they logged notes and managed assets. “We stripped it back to what they actually needed,” he explains. “Now they use it properly.”

The result is a stronger, more consistent operation with fewer errors and greater visibility across the board.

Where To Next — Growing with Simpro

LDN Security Solutions has no plans to change systems. “I expect Simpro to continue playing a major role in our future,” says Line. “It works, it’s scalable, and it’s deeply embedded in our business.”

The company regularly receives calls from competitors offering alternative CRM systems, but switching isn’t even a consideration. “Why would we start over?” Line adds. “We’ve grown with Simpro and it’s helped shape how we work.”
