Residential Electrical Repairs and Heating System Recommissioning
Case Study
When a homeowner reached out to SFR Electrical Services, they had been dealing with a faulty heating system for nearly two years. Despite multiple previous attempts by other contractors, the system had never worked as intended. With no documentation available and visible signs of poor installation, our team stepped in to assess, diagnose, and deliver a full electrical recommission.

The Challenge
This project presented a number of serious challenges. The client had been living with a system that failed to deliver the comfort and control they expected. The original installation was carried out by a tradesperson with limited electrical experience, leading to multiple underlying issues:
- No original wiring schematics or zoning diagrams
- Thermostats installed in incorrect locations that caused false readings
- Wiring routes that were disorganised and in some cases unsafe
- No labelling or documentation to identify zones or circuits
- A frustrated client who had already spent time and money without resolution
This was not a quick fix. It required a thorough understanding of the system, careful planning, and a professional approach.
Our Approach
From the beginning, we treated this as both a technical project and a client partnership. We carried out a full on-site inspection, checking every accessible component including thermostats, control panels, and cabling. We then sourced original layout drawings from the system’s manufacturer to build a complete picture of how the system was intended to operate.
Using this information, we mapped the actual setup and identified key discrepancies. Throughout the process, we kept the client informed, explaining our findings in simple terms and setting clear expectations for each stage of the repair.
Our Solution
Once the issues were fully understood, we carried out a series of focused repairs and upgrades:
Thermostat Repositioning
We relocated all thermostats to positions that accurately reflected room conditions, ensuring proper zone readings and improved user control.
Rewiring and Cable Management
We used discreet ceiling access points to reroute and correct wiring where needed. All connections were brought up to standard with tidy, compliant terminations.
System Labelling and Documentation
Every circuit, thermostat, and control cable was clearly labelled. A simplified reference layout was provided to the client for future maintenance or upgrades.
Testing and Commissioning
Each zone was tested under normal operating conditions to verify system behaviour and overall performance.
Client Handover
We completed a full walkthrough with the client, explaining how everything worked and answering all questions. The system was handed over fully operational and ready for long-term use.
The Results
The results of this project went beyond just technical success. The homeowner experienced a complete transformation:
Reliable System Performance
- Each zone now responds correctly, with smooth operation and consistent comfort throughout the property.
Energy Efficiency
- With accurate readings and corrected wiring, the system now uses energy more effectively and reduces unnecessary heating cycles.
Clarity and Confidence
- The client can now operate and understand the system with ease, supported by full labelling and guidance.
Future-Proofing
- Any future maintenance or upgrade work will be faster and more cost-effective, thanks to the logical system structure and clear documentation.
