Despite a turbulent period for the wider construction industry, the UK’s Building Energy Management Systems (BEMS) sector has demonstrated remarkable resilience. According to the latest Market Intelligence Report (MIR) from the Building Controls Industry Association (BCIA), the market grew by 2.6% in Q3 2025, with total revenues climbing to £210.1 million.
This growth comes at a time when the broader construction landscape has been hampered by rising material costs and a persistent shortage of skilled labour. The surge in BEMS activity is being credited to an intensified drive from architects, property developers, and designers to decarbonise the UK’s building stock through smarter automation.
BEMS Market Performance at a Glance (Q3 2025)
The BCIA report breaks down the sector’s performance into three core pillars. While some “rolling-year” figures show marginal shifts, the quarterly momentum indicates a sector successfully navigating economic headwinds.
| Category | Q3 Revenue | Quarterly Growth | Rolling-Year Total |
| Product Revenue | £38.8m | Stable | £162.1m |
| Installation Value Added | £112.9m | ⬆️ 2.2% | £455.8m |
| Service & Maintenance | £58.2m | ⬆️ 6.2% | £215.8m |
| Total BEMS Market | £210.1m | ⬆️ 2.6% | £1.03bn |
Key Drivers: Service, Maintenance, and Smarter Systems
A standout performer in the report was the Service and Maintenance category. Growing by 6.2%, this area remains one of the most resilient parts of the market, as facility managers increasingly focus on the long-term optimization of existing assets rather than just new builds.
In the Product category, manufacturer’s own systems saw a significant uplift of 8.3%, while distributor channels rose by 7.4%. This suggests that even when new construction slows, the demand for sophisticated, manufacturer-led controls remains high as owners strive to meet increasingly stringent sustainability targets.
Expert Insight: “Acknowledging the Need to Decarbonise”
BCIA President, Stacey Lucas, highlighted that the data reflects a fundamental shift in the built environment’s priorities.
“The construction industry has faced a challenging 2025, but it’s pleasing to see that the BEMS sector is remaining resilient. As more building owners strive to decarbonise their buildings and meet their sustainability targets, we remain confident that the BEMS sector will increasingly gain prominence.”
Lucas added that with the UK’s 2050 Net Zero target approaching, the role of building controls and automation is moving from an “optional extra” to a mission-critical component of building management.
The “Smarter Building” Future
The report indicates that the demand for BEMS is no longer purely about energy savings, it’s about data and intelligence. Facility managers and building owners are now using these systems to create “smarter” environments that offer better occupant comfort, real-time transparency, and a clear path to carbon neutrality.
For BCIA members, this quarterly insight provides a vital roadmap for identifying growth opportunities and navigating the complex economic climate with confidence.
