5.0 from 40+ reviews · 20+ years experience · NICEIC ApprovedTrusted Electricians for St Mellons & Trowbridge
Cardiff Electrical Home Rewire Ltd provides regular electrical services across St Mellons, Old St Mellons, Trowbridge, and the wider East Cardiff area. Our base in Llandaff gives us direct access via the A48 and Eastern Avenue — putting us at most St Mellons addresses within 20 minutes.
St Mellons has a unique housing profile that combines two distinct eras. Old St Mellons village retains character properties — stone cottages and period homes that require specialist electrical work. The newer St Mellons estate, Trowbridge, and recent developments like St Edeyrn's Village feature modern housing that still requires professional installation for EV chargers, home offices, smart systems, and circuit upgrades.
The newer estates built from the 1970s onwards were wired to the standards of their time — adequate for the appliances of that era but increasingly strained by modern electrical demands. Electric showers, multiple computing devices, EV chargers, and heat pumps create loads that original circuits were never designed to carry. We see regular overloading issues in these properties.
Our familiarity with the St Mellons area means accurate quoting, efficient scheduling, and an understanding of the specific access and property characteristics that affect job planning. Whether it is a period cottage in Old St Mellons or a new-build in St Edeyrn's, we know what to expect before we arrive.

Common Electrical Problems in St Mellons Properties
St Mellons spans several building eras, each with specific electrical characteristics and common failure points.
1970s–80s Estate Wiring
Properties on the original St Mellons estate and Trowbridge were wired 40–50 years ago. While not as old as Victorian wiring, these systems are approaching end-of-life and showing signs of insulation degradation.
Circuit Overloading in Modern Use
Estate properties designed for 1970s electrical loads now carry electric showers, multiple computers, EV chargers, and kitchen appliances that overwhelm original ring mains.
Old St Mellons Period Wiring
Character properties in Old St Mellons village can have wiring from various eras — some with original elements that need complete replacement to meet modern standards.
Garage and Extension Wiring
Many St Mellons properties have had garages converted or extensions added over the decades. The electrical work in these additions often lacks proper certification and Part P compliance.
Outdated Consumer Units
Properties from the 1970s–80s frequently retain original consumer units without modern RCD protection. These must be upgraded for safety and compliance.
New-Build Snagging Issues
Even newer St Mellons developments can have electrical snagging issues — poorly terminated connections, missing circuits, and installations that do not match specifications.
