Electrical issues come in many forms, and each one needs careful handling. At Langley EC, we support clients in Harpenden with electrical services that balance safety, practicality and clear communication. Whether it’s a quick repair or a full upgrade, we look at the job from the property’s point of view and choose an approach that fits its layout and condition.
Before we begin, we take time to understand the challenge. Some clients call because a circuit keeps tripping. Others want a lighting update or an EV charger fitted. Many need reassurance about the condition of an older installation. Every request starts with a short conversation to establish what you’re experiencing and what the property requires.
Instead of dropping everything into one category, we sort work into the following themes:
This makes it easy for you to see which items need urgent attention and which can be scheduled.
Lighting shapes how each room feels. We install everything from simple fittings to advanced smart-lighting systems that allow flexible, room-by-room control.
If your Harpenden property still uses outdated wiring, we can replace circuits, upgrade protective devices and reorganise the installation to reflect modern expectations.
Electric vehicle owners rely on a safe charging point. We check load capacity, placement and cable routing before installing an EV charger that works for daily use.
We carry out condition reports for landlords, homeowners and businesses. These inspections identify wear, defects or safety concerns that may need attention.
EXCELLENT Based on 32 reviews Posted on James DeanTrustindex verifies that the original source of the review is Google. Liam recently helped us with initially what we thought was a short circuit problem but helped and guided us professionally through what we needed to do to bring our electrics up to a modern safe standard. Liam was not pushy and gave lots of options of how we could tackle the problem. The work was of a really high standard and worked extra hours to help us get the job finished on time. Would absolutely recommend.Posted on Pooja NirmalTrustindex verifies that the original source of the review is Google. I recommend using Langley Electrical Contractors. We were without power due to a fuse box minor fire. We got in touch with Langley Electrical Contractors and within the same day they connected a new fuse box and gave us power. Thank you again for your professionalism and prompt service. I will use you again!Posted on Nivan SithamparanathanTrustindex verifies that the original source of the review is Google.

I would highly recommend Langley Electrical. Liam came to complete a few jobs for me at my home in Harrow and carried out the works to a high standard and at a very reasonable price. Liam was professional and friendly from start to finish and will definitely be my go to contractor in the future.Posted on Jonathan LangleyTrustindex verifies that the original source of the review is Google. Top class work Top class lad tooPosted on JonTrustindex verifies that the original source of the review is Google. Right from the outset Liam was communicative, professional and very helpful with providing feedback as to our switch wiring issue, and troubleshooting the technical problems. Upon attending our property Liam fixed our issue, supplied an improved quality socket, and was polite, friendly and, once again, more than willing to share his considerable knowledge in familiarising us with the workings of the system, and best practices for effective management of the system. We were very appreciative of his excellent service. Would not hesitate to recommend.Posted on David WilliamsTrustindex verifies that the original source of the review is Google. This morning when unplugging an iron from a downstairs socket there was a loud bang and flash from the socket and the 32amp circuit breaker on our consumer unit popped out. When trying to reengage the circuit breaker it just kept ‘kicking out’ 😮 So there we were the fridge / freezer off line, no WiFi, no idea what to do 🙈 Luckily we had the number for these guys, who answered the phone immediately, spoke to us in a friendly proffers manner, calming us down and quickly booked us in for a visit even on a Friday afternoon. Just great customer service. Highly recommended ⭐️ ⭐️⭐️Posted on MildaTrustindex verifies that the original source of the review is Google. I was recommended Langley Electrical Contractors by a friend, and I’m so glad I went with them. They came out to do some electrical work at my place in Harrow and honestly made the whole thing really easy. The team were on time, friendly, and explained what needed doing without any jargon. The work was done to a really high standard and they left everything neat and tidy afterwards. It’s not often you find tradespeople you can fully trust, but these guys gave me real peace of mind.
