Black & White Facilities / Service brief
Heating Controls
Rooms that never reach temperature, schedules that do not match occupancy, control faults, a change in how the building is used or an upgrade that touches the controls all bring this service into play. Describe the zones, the schedules, the pattern of complaints, the sensors, valves and plant, and any change in occupancy.
Overview
The figure on a controller screen shows what the system was asked to do, not whether valves, sensors, plant and emitters have done it, so controls are assessed with the heating system they drive rather than on their own.
Our full service catalogue, including every individual service, is available across every listed sector and location. For one site or several, we agree the scope, access and programme around the buildings concerned.
What the work can include
The scope can include assessment of the control system, sensors, programmers, valves, zoning, interfaces and defined repair or improvement work. The written scope names the zones, sensors, control sequence and settings covered and what is supplied or tested at completion; further repairs, specialist design, testing or replacement are separate unless included.
At completion the client receives the zones, sensors, control sequence and settings as left, with any limitation, interface with other trades and recommended next action.
Important decisions
The decision that matters most is how the controls interface with sensors, plant, valves and occupied spaces; settle it against the way the building operates and the client’s approval route so a change in sequence or setpoint does not run ahead of sign-off.
Before we visit
Scoping calls for control drawings, zone layout, schedules, complaint pattern, plant and valve details, access to panels and rooms and any planned changes. Across an estate, give each building a reference and keep asset and area labels consistent so findings from one control system are not confused with another.
Say whether occupancy has changed since the controls were last set up, and confirm which rooms and panels can be accessed.
How the work proceeds
Map the control arrangement as installed, compare intended and actual response, define the repair or alteration, test the agreed sequence and document settings and limitations. The client then has the zones, sensors, sequence and settings needed to choose between a settings change, a sequence change or a controls repair.
What affects cost and timing
Pricing and programme are driven by the number of zones, compatibility with existing equipment, sensors, access, out-of-hours testing, commissioning and coordination with plant or electrical work. For a managed site or estate, give the operating window, site access contact and shutdown constraints that apply to controls work.
Sector and property applications
Offices, education, retail premises and industrial sites all raise controls issues, and the work is arranged around zones, user complaints, sensor access and testing of the control sequence. Use the sector directory to see how the requirement varies between them.
Local coverage
We cover sites in Northumberland, Tyne and Wear, County Durham and Tees Valley, among them Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees, Middlesbrough and Redcar and Cleveland. On an estate, record zones, sensors, control sequence and settings for each building on its own. Full list of locations.
Frequently asked questions
Will new controls work with an older boiler?
In some cases. It depends on the boiler’s own controls, valves, sensors, communication method, electrical supplies and the sequence required, so the whole arrangement is assessed rather than one component. For estate planning, keep zones, sensors, sequence and settings on record per building so each site’s next decision is clear.
Why is a displayed temperature not reliable on its own?
The number shown may be one sensor position or the requested setpoint, neither of which proves heat is being delivered; valve operation, plant response, sensor position and room conditions all bear on the outcome. Where investigation affects occupants or operations, agree access, shutdowns and the interface with any retained contractor before scheduling.
Is radiator balancing part of controls work?
Not by default. Balancing is a hydraulic or distribution task; controls work may be coordinated with it, but the instruction has to say whether balancing is included. The completion information should confirm what was included, anything not completed and the follow-up required.
What information helps diagnose a controls fault?
Control drawings or panel details, zones, schedules, complaint pattern, plant and valve information, accessible rooms and any change in how the building is used or occupied. In a planned programme, the finding then decides whether further controls work or related remedial work is needed.
Knowledge and guidance
For the interfaces between sensors, plant, valves and occupied spaces, read what a building management system does and commercial mechanical plant maintenance. The service assessment then applies that guidance to the building or estate, read with its operating duty, access and approval route.

Contact Black & White Facilities with the site or estate, the zones, sensors, control sequence and settings as far as known, the records you hold and the operating constraints; we define the client interface and scope from that, with nothing assumed about response time or outcome.
