Integrated Doorset Solutions (IDSL) Group has marked a year of significant growth following the first year of its partnership with LDC, part of Lloyds Banking Group.
Founded in 2016, Mansfield-based IDSL Group comprises three businesses. IDSL is a leading manufacturer of specialist performance doorsets, including fire and security doors, for use in hospitals, schools, student accommodation, commercial and high-end residential properties. Additionally, Fire Door Inspection Solutions (FDIS) and Hartland Fire both specialise in inspection, maintenance and replacement activities across the UK.
In the 12 months since the investment, the business has seen a 21% increase in turnover to £42.9m. This performance reflects a continued focus on operational improvement, investment in delivery and infrastructure, and financial discipline.
IDSL Group began the current year with a strong order book and has continued to build momentum. Headcount has also risen by 47% to 420 people, supporting capacity growth and rising customer demand.
Since LDC’s investment in May 2024, IDSL Group has strengthened its leadership team with the appointment of Adrian Ringrose as chair and Brian Talbot as a non-executive director. Andrew Gratton is also set to join in August as chief operating officer.
Adrian was previously chair of Churches Fire & Security, while Andrew joins from global manufacturer ams OSRAM. The business also completed the acquisition of Hartland Fire in November 2024, broadening its capabilities in passive fire upgrades within defence estates.
The Group is also in the process of expanding its manufacturing footprint and is on track to open a new site in Mansfield later this year to increase capacity and support future growth, and continues to invest in new technology and equipment to drive efficiency.
Alongside its financial performance, IDSL has made meaningful progress on its environmental, social and governance (ESG) agenda. It achieved ISO 14064 accreditation to establish a clear baseline for carbon measurement, introduced a new fleet emissions reduction programme and enhanced waste management processes in line with new national recycling legislation.
IDSL also maintained its FSC certification following a successful audit, demonstrating that the timber used in its products is responsibly sourced from well-managed forests, and expanded its community engagement through new partnerships with local education providers and grassroots sports teams, including an internship placement programme with West Notts College and support for the under-7s team at Ravenshead Reds FC.
Ash Malhan, founder and managing director of IDSL, said: “Our first year with LDC has been defined by real progress – financially, operationally and culturally. LDC’s support and financial backing has enabled us to accelerate our growth strategy, invest in talent and infrastructure, and make headway on our sustainability goals.
“The support and insight David and the team have provided has been invaluable, and we’re incredibly proud of what the team has achieved so far. We’re now focused on building from this foundation and continuing to scale in a way that’s sustainable, strategic and people-first, including considering more opportunities to acquire.”
David Bains, partner and head of LDC in the East Midlands and East of England, added: “IDSL’s performance over the past 12 months is testament to the strength of its management team, the quality of its product offering and its commitment to client service.
“The team has delivered impressive growth, extended its reach and taken meaningful steps to future-proof its operations. We’re excited to support Ash and the team as they continue to build a standout business in the sector.”
LDC invested in IDSL in May 2024 to support the company’s growth strategy, with a focus on operational scale, leadership development and strategic acquisitions.
