DSSL Secures Greener Future with BigChange

Using the cloud, based 6-in-1 BigChange solution, which includes vehicle tracking and a mobile workforce app, together with intelligent job scheduling and an online customer booking portal, DSSL has already offset more than 200 tonnes of CO2 and achieved net zero running for its fleet of engineering vehicles. The Essex-based company has also reduced its paper production and consumption by around 20,000 sheets per annum, further contributing to its green credentials.

A multi-system solution for managing routine, daily activities such as job raising and invoicing which was resource and paper intensive.


A single cloud-based system that offered tangible savings and service improvements.

Predominantly specialising in Local Authority CCTV systems and access control systems for Housing Associations, DSSL operates a mixed fleet of more than forty vans and five cherry pickers from its regional operation centres in Essex, Leeds, and London. Completing around 100 planned jobs a day with an additional 15-30out-of-hours callouts, DSSL implemented BigChange to replace several disparate and outdated systems.

"Before BigChange we had a job sheet system that was server based, we used Google Calendar, a separate racking system, and multiple spreadsheets to manage daily activities such as job raising and invoicing,” commented Aaron Stephens, Managing Director of DSSL Group.

“Engineers couldn’t create jobs when responding to call outs, which meant we needed a dedicated member of staff to raise these retrospectively and chase engineers for the required information to close the job for invoicing. We also had another member of the admin team whose job it was to print completed job sheets and get them marked up for invoicing.”

DSSL selected the BigChange job management system after just one face-to-face demo.

“We knew how our business operated and the workflows that were required to get jobs done and invoiced,” he continued. “However, we also knew this was long winded.

“We knew we wanted a cloud-based system and it very quickly became apparent that the Big Change methods and processes were aligned with what we needed to achieve, and the functionality and vision were there to save us resources from day one, boosting customer service and supporting us as we continue to grow.”

Since implementing BigChange, DSSL has dramatically reduced its back-office administration resources and environmental impact. Automated workflows and integration of management systems have meant that two, full-time staff members have been redeployed within the business equating to a saving of around £60,000 per annum.

Still in the early stages of system adoption, DSSL is also realising improvements in cash flow due to more timely and accurate invoicing and improved management reporting.

DSSL customers are also noting the changes in the business with real-time sharing of information between the field and the office and more detailed and comprehensive reporting.

Southern Housing, one of the largest Housing Associations in the UK with more than 45,000 homes across London, the South East, and the Midlands, which uses DSSL access control solutions, commented, “We are delighted with DSSL and their performance as they continue to deliver against our targets and KPI’s.

“Best of all is their ability to communicate and put in place processes and procedures to keep customer satisfaction at 98% and complaints to a very low level.”

Some additional features within the BigChange system, such as vehicle checks, driver behaviour alerts, and improved field reporting, are also helping DSSL look after their workforce promoting safer and greener driving and identifying additional training requirements.
