Building Management Systems

PHD Mechanical offers 24/7 support, providing a point of contact when a building services fault needs urgent attention. For a controls-related problem, explain which systems are affected, any displayed alarms and the impact on occupants. Our team can discuss the appropriate response and confirm availability for your installation.

Reactive work addresses an existing fault; planned preventative maintenance focuses on scheduled checks and servicing. Our wider maintenance provision includes heating pumps and controls. When discussing a maintenance agreement, identify the BMS equipment, connected plant and reporting requirements so the included tasks and responsibilities can be clearly established.

We welcome enquiries from contractors and facilities teams across:

• Offices and retail: temperature control and operating schedules.
• Healthcare: service continuity and coordinated access.
• Hospitality: guest comfort and extended operating hours.
• Industrial and warehouses: controls for larger spaces.
• Residential and mixed-use: shared heating and varied occupancy.
• Construction and refurbishment: controls and mechanical services coordination.

Our experience includes heating controls upgrades at Spire House, a six-storey residential development, and controls and building energy management work at Aspire Leisure Centre, within the grounds of the Royal National Orthopaedic Hospital. These projects demonstrate our experience with communal systems and occupied buildings, with each new project assessed individually.

Can you work with contractors on existing building controls?

Yes. Our published work includes upgrading controls on an existing three-boiler system at Spire House in London. Send us the controls manufacturer, equipment details, drawings and proposed changes so we can assess compatibility and scope. Support for a particular platform or integration should be confirmed before it is included in the project specification.

What compliance information should contractors request before appointing you?

Contractors can ask our team for the credentials and supporting documentation relevant to the proposed work. PHD Mechanical operates a safety programme supported by an independent professional safety consultant. Specify any requirements for risk assessments, method statements, testing records and handover information during the enquiry stage so their availability and scope can be confirmed.

Can a BMS help facilities managers reduce unnecessary energy use?

A BMS can help managers review operating information and adjust connected services to suit the building’s needs. For example, reviewing when equipment operates may reveal opportunities to avoid unnecessary running. Any savings depend on the existing system, building use and changes implemented; a fixed reduction should not be assumed.

What is the difference between reactive support and planned controls maintenance?

Reactive support addresses a fault that has already occurred. Planned maintenance involves agreed checks and servicing at scheduled intervals. Facilities managers should establish which controls and connected assets are included, how faults are reported and what records will be provided. This helps clarify responsibilities and supports maintenance budgeting.

What areas do you cover, and how can I confirm pricing and attendance?

PHD Mechanical serves London and the South East, with offices in Harrow and Central London. Contact us with your postcode, system details and the urgency of the request. Our team can confirm availability and discuss whether an initial assessment is required before quoting. Ask for applicable charges and the proposed scope to be clarified before authorising work.
