Intelligent Monitoring Group to buy UK residential security provider for $347m

Intelligent Monitoring Group (IMG), a WA-based provider of monitored security and IoT solutions, has entered into a binding agreement to acquire ADT’s residential security business in the UK (ADT UK Residential) from a subsidiary of Johnson Controls International.

The acquisition will be funded through a combination of a new debt facility and a vendor equity placement, with the total consideration of £180 million (A$347 million) comprising of £155 million in cash and £25 million of IMG shares as consideration to Johnson Controls International.

Providing an immediate presence in the UK market for the company, the acquisition is set to add A$12.5 million per month recurring revenue from more than 160,000 direct customers in what IMG claimed is one of the largest monitored security markets.

It is also expected to increase IMG’s pro forma annualised EBITDA by around 300% to A$130 million.

IMG said that buying ADT UK Residential provides a platform for future growth initiatives, including video monitoring solutions, and is consistent with IMG’s strategy of acquiring "high-quality security businesses with strong customer relationships and established market positions".

That strategy has seen IMG complete five acquisitions in the last three years, the latest coming at the end of last year, when the company bought fire protection service company Tyco NZ and security provider Red Wolf from a subsidiary of Johnson Controls International for $40 million.

Also in 2025, the company bought WA-based security provider Western Advance, as well Queensland-based security systems provider KOBE.

2024 saw a pair of deals worth just shy of $16 million, with IMG acquiring security systems firms Alarm Assets Group and ACG Integration - based in Perth and Sydney respectively - while in 2023, IMG bought the entire customer base of Victorian security operator Bellrock Group.

IMG MD Dennison Hambling said that following the acquisition of ADT's businesses in Australia and New Zealand in 2023, IMG has developed a unique understanding of ADT's operating model and brand.

"This experience underpins our confidence in both the quality of the asset and IMG’s ability to effectively integrate, operate and grow the business," he said.

"ADT UK Residential will continue to operate as a standalone business post-completion, with IMG expecting an orderly and disciplined transition process given its established operating model.

"This acquisition represents a further step in IMG’s strategy to build a scaled, diversified security, monitoring and life-safety solutions platform with resilient recurring revenues and attractive long -term growth across key markets.”

Completion is expected in the first half of 2027.
