Carrob Controls

What Carrob Controls does

Carrob Controls & Services Ltd is a UK specialist controls contractor founded in 1988 and headquartered in Hemel Hempstead. The company designs, manufactures, installs and commissions Building Energy Management Systems (BEMS), control panels and packaged AHU (Air Handling Unit) control solutions for enterprise and institutional customers. Manufacturing is performed in-house, covering sheet metalwork, panel assembly and full system build, which differentiates the company from controls-only system integrators.

Its commercial offering spans the full project lifecycle: front-end design and consultancy, OEM co-developed packaged control products, on-site installation, commissioning, and a dedicated service and maintenance arm intended to generate recurring aftermarket revenue. The company holds formal OEM certifications with the dominant UK BMS platforms — Honeywell, Trend and Tridium — giving it protocol-level access across the installed base. Its technical documentation has been independently validated by BSRIA as best-in-class, a credential it uses in regulated tender processes.

Carrob's customer base is concentrated in the UK and skewed toward healthcare, with named projects for the NHS (including Great Ormond Street, St Thomas's and Derriford hospitals) and private hospital groups (Spire Healthcare, Bupa). Additional named clients span education (UCL), museums (Royal Academy), retail (Marks & Spencer), hospitality (Sheraton) and industrial (British Aerospace). The company is privately held, has been self-financed since inception, and operates with 11–50 employees, covering UK sites from Plymouth to Edinburgh and shipping packaged control products internationally to Poland and India.
