• UK Building Controls Market Remains Stable At £840m Despite Slight Q4 Dip

20 March 2026 | Updated 18 March 2026

The UK building controls and Building Energy Management Systems (BEMS) market remained broadly stable in 2025, reaching a total value of £840.4 million despite a slight slowdown in the final quarter, according to the latest market data from the Building Controls Industry Association (BCIA).

The BCIA publishes its Market Intelligence Report quarterly, providing detailed data on trends, revenues and growth opportunities across the BEMS sector.

The Association’s latest Market Information Report shows total industry revenues for Products, Installed Systems and Service & Maintenance supplied into the UK market fell slightly in Q4 2025 to £207.5 million, a 1.2% decrease compared with the previous quarter.

Despite this marginal quarterly softening, the overall annual picture indicates a resilient sector, with total market value rising by 0.1% year-on-year across 2025.

Product Supply Remains Steady

Product revenues increased modestly during the final quarter of the year, rising by 0.5% to £39.0 million. Original Equipment Manufacturer (OEM) sales continued to recover, although distributor channels remained more subdued.

Across the full year, product performance was mixed, with growth in OEM activity helping offset weaker demand through distribution channels. Overall, product supply remained broadly stable and accounted for just under one-fifth of total market value.

Installed Systems Activity Eases

Installation Value Added declined by 2.3% in Q4 to £110.5 million, reflecting softer installation activity across parts of the market during the year.

On an annual basis, installed systems revenues also eased slightly. However, the proportion of value added within installed systems remained stable, underlining the continued importance of engineering expertise, commissioning and integrated system delivery in modern building performance.

Service and Maintenance Continues to Grow

Service and Maintenance once again proved to be one of the most resilient areas of the sector. While revenues dipped slightly in the final quarter, the segment recorded annual growth of 2.1%, reaching £220.1 million and increasing its share of overall market value.

The continued expansion of service activity reflects the growing importance of long-term system optimisation, maintenance and building performance management across commercial estates.

Industry Outlook for 2026

Overall, the data suggests that while 2025 did not deliver strong headline growth, the market demonstrated notable resilience. Stable product demand, consistent system pricing structures and continued expansion in service revenues helped maintain overall market value.

As the industry moves into 2026, the report suggests a market environment characterised more by consolidation and careful investment than rapid expansion.

Jen Vickers, President of the Building Controls Industry Association, said: “While the latest figures show a slight softening in activity during the final quarter of 2025, the overall picture is one of resilience. The building controls sector continues to play a vital role in helping buildings operate more efficiently, reducing energy consumption and supporting the transition to net zero.”

Vickers continued: “The continued growth in service and maintenance also reflects a broader shift in how buildings are managed, with organisations increasingly recognising the value of optimising existing systems and improving operational performance. As we move into 2026, the focus across the industry will be on steady investment, skills development and ensuring building controls remain central to delivering smarter, more efficient buildings.”
