A displayed temperature or controller setting does not prove that valves, sensors, plant and emitters respond correctly; controls must be assessed as part of the system they operate.
What the work can include
The agreed scope can include control-system assessment, sensors, programmers, valves, zoning, interfaces and defined repair or improvement work. The agreed scope names zones, sensors, control sequence and settings and states what will be supplied or tested at completion. Additional repairs, specialist design, testing or replacement are separate unless expressly included.
At completion, the owner or agent receives zones, sensors, control sequence and settings; any access limitation and the next job decision are stated.
Important decisions
Understand control-system interfaces between sensors, plant, valves and occupied spaces. Relate this choice to the property condition, access arrangement and owner or agent’s next instruction.
Assessment and preparation
Before arranging the work, provide control drawings, zones, schedules, complaint pattern, plant and valve details, access to panels and rooms, and planned changes. For a managed or shared property, identify the owner, occupier, managing agent and person authorised to approve access or additional work.
Provide control drawings or panel details, zones, schedules, complaint patterns, plant and valve information, room access and any occupancy change.
How the work proceeds
Map the control arrangement, compare the intended and actual response, define repair or alteration, test the agreed sequence and document settings or limitations. At handover, the owner or agent can use zones, sensors, control sequence and settings to decide the settings, sequence or control repair next step.
Cost, timing and disruption
Scope and price are affected by number of zones, compatibility with existing equipment, sensors, access, out-of-hours testing, commissioning and coordination with plant or electrical work. For a property job, provide the access arrangement, occupier or agent contact and any restriction on use relevant to heating controls.
Sector and property applications
Owners, landlords, managing agents and occupiers may need heating controls scoped around zones, user complaints, sensor access and testing the control sequence. The sector directory provides the wider property context.

We cover Northumberland, Tyne and Wear, County Durham and Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle upon Tyne, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees, Middlesbrough and Redcar and Cleveland. For a property job, send the address with zones, sensors, control sequence and settings and the access or responsibility contact. View all locations.
Frequently asked questions
Can new controls work with an old boiler?
Sometimes. Compatibility depends on the boiler controls, valves, sensors, communication method, electrical supplies and required sequence; the complete arrangement must be assessed. For a property job, confirm zones, sensors, control sequence and settings with the owner or agent before work is arranged.
Why can a displayed temperature be misleading?
A displayed temperature may represent one sensor location or a requested setpoint, not actual heat delivery. Valves, plant response, sensor position and room conditions also affect the result. Access through occupied rooms, shared areas or neighbouring land should be agreed with the occupier or agent before the visit.
Does controls work include balancing radiators?
Not automatically. Radiator balancing is a hydraulic or distribution task; controls work may coordinate with it, but the instruction should state whether balancing is included. The job decision should distinguish immediate making-safe work from a later repair, replacement or improvement instruction.
What information helps diagnose a control fault?
Provide the control drawings or panel details, zones, schedules, complaint pattern, plant and valve information, accessible rooms and any changes to use or occupancy. At handover, give the owner or agent the property-specific record, outstanding action and any restriction on use.
Knowledge and guidance
Read what a building management system does and commercial mechanical plant maintenance to understand control-system interfaces between sensors, plant, valves and occupied spaces. Use the service assessment to apply that guidance to the property or site. For a property job, use this guidance alongside condition, access and the owner or agent approval route.
