Every electrical project tells a story – of problems solved, homes improved, and safety restored. In this article, we share real case studies from our work across Cheshire, demonstrating the types of challenges we encounter and how we solve them. These examples illustrate the importance of professional electrical work and may help you recognise similar issues in your own property.
Case Study 1: Victorian House Rewire
The Challenge
A beautiful Victorian property in Altrincham had original wiring from the 1920s, with rubber-insulated cables that had deteriorated significantly. The homeowners were experiencing frequent blown fuses, flickering lights, and had concerns about safety following a small electrical fire in a neighbour's similar property.
What We Found
Our initial inspection revealed:
- Perished rubber insulation exposing bare conductors
- No earth connection to most circuits
- An ancient fuse box with rewirable fuses and no RCD protection
- Overloaded circuits with multiple extensions and adapters
- Several junction boxes hidden in the loft with dangerous connections
The Solution
We carried out a complete rewire, working carefully to preserve the property's period features. The project included:
- Full rewire with modern twin and earth cable
- New 18th Edition consumer unit with RCD protection
- Additional circuits to meet modern demands
- Sympathetic socket and switch placement
- Period-style accessories to match the property's character
The work was completed over two weeks, with the family able to remain in the property throughout. The result was a safe, modern electrical installation that respects the home's heritage while meeting all current standards.
Case Study 2: Commercial Kitchen Electrical Upgrade
The Challenge
A popular restaurant in Wilmslow was expanding their kitchen and needed additional power for new commercial equipment. The existing single-phase supply was insufficient, and the installation needed to meet stringent commercial kitchen requirements.
What We Found
The existing installation had several issues:
- Single-phase supply inadequate for planned equipment
- Consumer unit at capacity with no room for additional circuits
- Some circuits not suitable for the kitchen environment
- Emergency lighting not compliant with current standards
The Solution
Working closely with the restaurant owner and equipment suppliers, we designed and installed:
- Three-phase supply upgrade (coordinated with the DNO)
- New commercial-grade distribution board
- Dedicated circuits for each major appliance
- IP-rated sockets and switches suitable for kitchen use
- Compliant emergency lighting throughout
- Extraction system electrical connections
The work was completed during the restaurant's annual closure, minimising business disruption. Our restaurant electrical installation service ensured full compliance with commercial kitchen requirements.
Case Study 3: EV Charger Installation with Consumer Unit Upgrade
The Challenge
A homeowner in Knutsford had purchased an electric vehicle and wanted a home charger installed. However, their 1980s consumer unit had no spare ways and lacked RCD protection, making a straightforward charger installation impossible.
What We Found
Assessment revealed:
- Old consumer unit with no spare capacity
- No RCD protection on any circuits
- Main earthing arrangement needed upgrading
- Long cable run required to reach the garage
The Solution
We proposed a combined upgrade that would future-proof the property:
- New 18th Edition consumer unit with dual RCDs and ample spare ways
- Earthing system upgrade to TN-C-S
- 7kW smart EV charger installation in the garage
- Armoured cable run with proper burial depth
- Load management to prevent overloading
The customer now has a modern, safe electrical installation with room for future additions, plus convenient home EV charging. Our EV charger installation service includes full assessment and any necessary upgrades.
Case Study 4: Emergency Fault Finding
The Challenge
A family in Stockport called us on a Saturday evening after losing power to half their house. The RCD kept tripping immediately when reset, leaving them without lighting or power to the kitchen.
What We Found
Our emergency call-out revealed:
- Water ingress into an outdoor socket from a damaged seal
- The socket had been installed by a previous owner without proper weatherproofing
- Moisture had caused a fault to earth, triggering the RCD
The Solution
We were able to resolve the issue that evening:
- Isolated the faulty circuit to restore power to the rest of the house
- Removed the damaged outdoor socket
- Installed a properly rated IP66 outdoor socket with correct weatherproofing
- Tested all circuits to confirm safe operation
The family had full power restored within two hours of our arrival. Our electrical fault finding service uses systematic testing to quickly identify and resolve problems.
Case Study 5: Smart Home Lighting Installation
The Challenge
A tech-savvy homeowner in Hale wanted to upgrade their entire home to smart lighting, with voice control, automated scenes, and integration with their existing smart home system. The property had a mix of lighting types and some switches without neutral wires.
What We Found
The existing installation presented several challenges:
- No neutral wires at most switch locations (common in UK homes)
- Mix of LED, halogen, and incandescent fixtures
- Some incompatible dimmer switches
- Complex three-way switching arrangements
The Solution
We designed a comprehensive smart lighting system:
- Ran neutral wires to key switch locations where needed
- Installed smart switches compatible with the customer's chosen ecosystem
- Upgraded all lighting to dimmable LED
- Configured scenes and automations per customer requirements
- Integrated with voice assistants and the existing smart home hub
The result is a fully integrated smart lighting system controlled by voice, app, or traditional switches. The customer reports significant energy savings and loves the convenience of automated lighting scenes.
Lessons from Our Projects
These case studies highlight several important themes:
- Age matters – Older installations often have hidden issues that only become apparent during inspection
- Planning pays off – Combining related work (like EV chargers and consumer unit upgrades) is more cost-effective than separate projects
- Professional assessment is essential – What seems like a simple job often reveals underlying issues that need addressing
- Quality installation prevents problems – Many faults we fix result from poor previous work
- Future-proofing saves money – Installing capacity for future needs avoids costly upgrades later
Conclusion
Every electrical project is unique, but they all share common elements: the need for proper assessment, quality workmanship, and compliance with regulations. Whether you're facing an emergency fault, planning a major upgrade, or simply want to improve your home, professional electrical services ensure the job is done safely and to the highest standards.
