Founded as a garden city in the 1920s, it has a lot of interwar homes alongside later estates. Houses of that age, especially those that have been extended or rewired in stages, are often worth a full condition report before work or a sale.
Commercial work here ranges from the town centre and the Howard Centre to the offices and employment areas on the edge of the town. We handle testing, lighting upgrades, emergency lighting and installation.
For businesses in Welwyn Garden City, an electrical fault is lost trading time. Ring the office, tell us what has stopped working, and we send the nearest engineer to make it safe and get you running again, with any larger repair quoted in writing.
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 Welwyn Garden City
How quickly can an emergency electrician get to Welwyn Garden City?
Call 0345 3 822 833 between 8am and 5pm, Monday to Friday. Welwyn Garden City is about 11 miles from SEG House and we aim to have an engineer on site within one hour of your call.
Do you attend emergencies in Welwyn Garden City 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 Welwyn Garden City?
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 Welwyn Garden City?
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 Welwyn as well as Welwyn Garden City?
Yes. We cover AL6, AL7 and AL8 as well as the surrounding villages. Call with your postcode.
How old is too old for electrical wiring in an interwar house?
There is no single age limit. The condition of the installation matters more than the date, which is why we inspect and test and then tell you what, if anything, needs to be done.
Need it done by a date?
Tell us the deadline. We’ll tell you honestly whether we can hit it — and we usually can.
