Croma Security Solutions Group plc acquires Added Security Technology Limited

The total consideration for the acquisition is approximately £1.74 million and includes cash balances of £0.80 million and a freehold property, from which the business trades, valued at £0.53 million.

For the year ended 31 August 2025, Added Security Technology Limited generated revenue of £1.8 million and adjusted EBITDA of £0.3 million.

The total consideration will be satisfied primarily in cash from Croma Security Solutions Group’s existing cash reserves, together with £36,000 satisfied through the transfer of 52,863 ordinary shares at the price of 68.1 pence per share (the ‘Consideration Shares’) held in treasury and up to £50,000 of deferred consideration payable following the collection of certain trade debtors during the six months following completion.

Experienced team

Founded over 30 years ago, Added Security Technology Limited is a specialist supplier and installer of communal door entry and intercom systems, key fobs and secure entrances, together with a growing specialism in hearing impaired living aids such as hearing loops and flashing doorbells. The business also provides locksmith services to its customer base.

Added Security Technology Limited holds an established contract with a local council, recently renewed for a further ten years, covering the installation of door entry systems and entrance doors across the council’s social housing programme, alongside further contracts with regional housing associations and commercial clients.

In total, Added Security Technology Limited employs 23 members of staff, all of whom are locally based and will join the Croma Security Solutions Group as a result of the acquisition. This highly experienced team is a significant addition to the Group’s engineering and advisory capability.

Complementary operation 

Croma Security Solutions Group is proud to be acquiring a local, family-run business with a longstanding reputation in Portsmouth. Given Added Security Technology Limited’s position within the local housing sector, underpinned by its long-term intercom and door entry contract with the City Council, the acquisition is complementary to Croma’s existing capability across industry and provides a strong platform for the Group to broaden its service offer.

The vendors, namely Paul and Susan Sullivan, will retire from the business upon completion of the deal, having led Added Security Technology Limited since founding the company back in 1995. Their son James Sullivan, currently serving as general manager, will continue to lead the team, enabling a smooth transition into the Croma Security Solutions Group.

Roberto Fiorentino, CEO at the Group, commented: “We are delighted to announce the acquisition of Added Security Technology Limited, which is the largest acquisition in Croma’s history since the disposal of Vigilant. Having known the business for many years, we are confident that Added Security Technology Limited will be an excellent addition to the Group. It has built an excellent reputation, underpinned by a loyal customer base and recognised expertise in specialist security systems.”

Fiorentino added: “In addition to the operational and commercial synergies that this acquisition brings, we see significant opportunities to leverage Added Security Technology Limited’s specialist technical capabilities across our network of security centres.”

Added Security Technology Limited’s founder Paul Sullivan responded: “We have been a family business for over 30 years and I’m immensely proud of what the team has built. Joining the Croma Security Solutions Group represents the right next step for the business and for our staff, giving them the backing of a larger organisation while keeping our local presence and approach that our customers value. I look forward to seeing Added Security Technology Limited continue to grow as part of the Croma Group.”
