Fault finding investigates a reported problem to identify its cause or narrow the possible causes. Diagnostics uses appropriate observations, measurements and tests to support the next repair, monitoring or replacement decision.
Discuss fault finding and diagnostics
An alarm, intermittent trip or loss of output may have more than one explanation. Replacing the most obvious component without understanding the operating conditions can leave the original issue unresolved.
We define what needs investigating and use the findings to establish the next step. A diagnostic visit may produce a confirmed fault, a repair scope or a requirement for further evidence under different conditions.
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.
This example was delivered by the separate Black & White Property Services business. Occupied plots at a residential park lost power because of a fault in their connected supply. Black & White Property Services used sectional testing to identify and isolate a damaged cable section, then altered the working supply arrangement. Power was restored; permanent cable replacement and further site checks remained follow-on recommendations. Electrical fault finding and power restoration at a residential park.
This example was delivered by the separate Black & White Property Services business. Failed circulation pumps and non-return valve problems affected heat distribution at a Newcastle building. Black & White Property Services replaced two pumps, cleaned and refitted the existing valves, then refilled, vented, balanced and tested the affected circuits. Heating circulation was restored without unnecessary valve replacement. Heating circulation restored to affected Newcastle building zones.
For facilities teams, estate operators and managing agents dealing with recurring or unexplained faults, uncertain repair recommendations or equipment that behaves differently during inspection and normal use.
The agreed scope identifies systems, symptoms, available records and the investigation required. Outputs include observations, relevant measurements, conclusions and the proposed next action, with any unresolved question explained.
Review fault history, inspect the affected system, compare operation with the expected function and carry out relevant tests. Diagnostic work may need access to connected equipment, controls or service records beyond the component named in the original report.
We establish the symptoms and impact, review existing information, agree the test scope and arrange access. Findings are evaluated before recommending repair or further investigation. The report separates confirmed evidence from possible explanations.
Provide error codes, times, conditions, asset details and earlier repairs. Explain whether the fault follows start-up, load changes or particular weather. Agree any shutdown or attendance needed to observe the equipment under representative conditions.
Technical investigation is undertaken through the appropriate competence and safe-working arrangements. The client supplies known hazards and operating restrictions. HSE maintenance guidance explains why equipment work needs planning and suitable expertise.
Urgent symptoms follow the relevant safety or emergency route. For ongoing investigations, we agree milestones and escalation when the evidence indicates a different risk or scope. Diagnosis and permanent repair retain separate completion points.
We record the equipment, symptoms, test conditions, findings and limits of the investigation. Keeping the circumstances with each reading makes later comparisons useful and avoids treating a normal result under one condition as proof of all operating states.
Intermittent faults, complex systems, access, test equipment, specialist input and the time needed to reproduce symptoms affect cost. We define the initial investigation and explain what further work would answer before extending it.
The handover states what was established, what remains uncertain and the next step. That may be a repair instruction, further testing or a defined observation period. Evidence and settings relevant to the investigation are retained in the work record.
You receive a reasoned basis for the next action. We connect symptoms to operating evidence so expenditure follows an understood requirement rather than repeated component replacement.
Industrial premises need load and production conditions recorded. Offices need occupancy and control schedules considered. Retail estates benefit from comparable histories across sites. Explore all sectors.
We arrange investigations across Northumberland, Tyne and Wear, County Durham and Tees Valley, including Newcastle, Gateshead, Sunderland, Durham, Darlington and Middlesbrough. Timing may need to match the conditions in which the fault occurs. View all locations.

The instruction defines whether a repair is included or needs a further decision. Diagnosis can establish the cause and required parts without completing the repair at the same attendance.
We record the conditions observed and any tests completed, then identify useful next evidence. An intermittent fault may need monitoring or attendance when the relevant operating conditions are present.
They show what has already been changed and how the fault developed. This helps avoid repeating an investigation without considering earlier findings.
Yes, where their interfaces form part of the agreed scope. We identify additional access or specialist input needed to assess those connections.
