Electricians in Harpenden, from a St Albans-based contracting team.
A short drive north of St Albans, and a regular part of our domestic and landlord work. SEG’s employed, NICEIC-registered engineers cover Harpenden for homeowners, landlords, housing providers and businesses, with the same head office and the same number to call.

Electricians working in Harpenden
Harpenden sits in the same council district as SEG House, a few miles north-east of Chiswell Green along the A1081, so it is one of the places our engineers reach most easily.
- Council area: St Albans City & District Council
- Postcodes: AL5
- From SEG House: about 7 miles by road (192 Watford Road, Chiswell Green, AL2 3EB)
Much of the housing is Victorian, Edwardian and interwar, with plenty of larger family homes that have been extended and altered over the years. Those mixed-age properties are where we see tired consumer units, older rubber or early PVC wiring and circuits added piecemeal, which is exactly what an EICR is designed to bring to light.
Harpenden also has a busy high street of shops, restaurants, surgeries and small offices. Testing and lighting work can be scheduled around trading hours.

Why use a contractor with a head office in St Albans
SEG is a commercial electrical contractor first and a local electrician second. For a Harpenden householder, it means the engineer who visits has the same training, certification and supervision as the team on a large programme, and tells you plainly what needs doing and what does not. We employ our engineers, we photograph and certify every job, and the office at SEG House answers the phone.
