Emergency electrician in Radlett
Radlett is about five miles east of SEG House, and one of the nearest towns to us on the way to the M25 and North London.
- Council area: Hertsmere Borough Council
- Postcodes: WD7
- From SEG House: about 5 miles by road (192 Watford Road, Chiswell Green, AL2 3EB)
Radlett has a lot of larger detached and semi-detached homes, many extended or modernised. Lighting upgrades, additional circuits and EV chargers are typical requests, and a condition report ahead of a larger project is sensible.
Local shops and professional premises can use our testing and lighting upgrades, scheduled around opening hours, and we also support commercial customers on the way into London.
For homes in Radlett, 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.

Questions we are asked in Radlett
How quickly can an emergency electrician get to Radlett?
Call 0345 3 822 833 between 8am and 5pm, Monday to Friday. Radlett is about 5 miles from SEG House and we aim to have an engineer on site within one hour of your call.
Do you attend emergencies in Radlett out of hours?
Our phones are answered 7am to 10pm, seven days a week. The one-hour response is promised Monday to Friday, 8am to 5pm; outside those times we take the details and tell you honestly when we can get an engineer to you. If anyone is in danger or there is a fire, call 999.
Why use a team rather than a one-man electrician in Radlett?
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 Radlett?
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 install EV chargers in Radlett homes?
Yes. We install home chargers, check the supply and earthing arrangements first, and can advise if the consumer unit needs to be upgraded.
Do you cover Shenley and Aldenham as well?
Yes. We cover the villages around Radlett as part of the WD7 and WD25 areas. Call with your postcode and we will confirm.
Need it done by a date?
Tell us the deadline. We’ll tell you honestly whether we can hit it — and we usually can.
