Emergency electrician 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.
For homes in Harpenden, the usual call is a consumer unit that keeps tripping, a socket or switch that has scorched, or power lost to part of the house. Switch off if it is safe, ring the office, and we send an engineer to find the fault and make it safe.
What counts as an electrical emergency?
- A burning smell, smoke, sparks or a scorched socket, switch or consumer unit.
- Exposed live wires, or a shock from an appliance or fitting.
- Water on electrics, or a flooded consumer unit.
- Power lost to your property when the neighbours still have theirs.
- A circuit that trips again straight after you reset it.
While you wait: stay safe
- If there is a fire, or anyone is injured, call 999.
- If it is safe and the area is dry, switch off the main switch at the consumer unit.
- Do not touch anything wet, damaged or scorched, and keep people and pets away.
- If the power is out across your street, call 105. It is free and reaches your network operator.

A team behind you, not just a one-man electrician
SEG is a team of employed, NICEIC-registered engineers with an office behind them, so one call starts a process rather than relying on one person being free. See how that compares on our main St Albans emergency electrician page. For everything else we do in Harpenden, see electricians in Harpenden.

Questions we are asked in Harpenden
How quickly can an emergency electrician get to Harpenden?
Call 0345 3 822 833 between 8am and 5pm, Monday to Friday. Harpenden is about 7 miles from SEG House and we aim to have an engineer on site within one hour of your call.
Do you attend emergencies in Harpenden out of hours?
Our emergency attendance runs Monday to Friday, 8am to 5pm, and that is when we promise the one-hour response. If anyone is in danger or there is a fire, call 999.
Why use a team rather than a one-man electrician in Harpenden?
Capacity. A sole trader cannot be on two jobs at once, and illness, holidays or a van breakdown can leave an emergency waiting. SEG has several employed engineers and vans and an office that sends the nearest one, so if one engineer is busy, another attends.
Who do I call if the power is out across the street in Harpenden?
Call 105 for free. It connects you to the network operator for your area, who deal with faults on the supply up to your meter. If only your property has lost power, call us.
Do you cover all of Harpenden, including Batford and Kinsbourne Green?
Yes. We cover the whole AL5 postcode area from our base in St Albans. Give the office your postcode when you call.
My Harpenden house has had several extensions. Can you check the wiring across all of it?
Yes. An EICR covers the whole installation, so older and newer parts are inspected together, and the report lists anything that needs attention in plain terms.
Need it done by a date?
Tell us the deadline. We’ll tell you honestly whether we can hit it — and we usually can.
