We are a group of honest, dedicated and
knowledgeable electricians.

Welcome to Powerlec Electrical and Testing Ltd. We are a group of honest, dedicated and knowledgeable electricians, working across South Essex and London, especially in Southend On Sea, Westcliff On Sea, Leigh On Sea, Shoeburyness, Thorpe Bay and surrounding areas. With friendly service, constantly updated accreditations and a strong code of conduct to keep you informed, treat your home or workspace as we would expect ours to be treated and use the most sustainable options, we aim to put the power in your hands
We know that electrics are a specialism that comes with a lot of compliance and paperwork but also connected safety concerns. It is essential, and in most cases a legal requirement that electrical work is carried out correctly, by people who have appropriate qualifications for the job. However, this shouldn’t mean that you, the customer, have to hand over any sense of choice when you need electrical works. We believe in ensuring you have all the facts you need to make a decision about what is right for your property, rather than confusing you with jargon. And we believe in costing jobs fairly, turning up on time and respecting your space: simple principles that we carry out all of our work to, from quoting to final inspection.

Ensuring your electrics are safe and reliable.

This website details our services, for homeowners, landlords, estate agents and businesses.

Powerlec Electrical and Testing Limited.

From the materials we use, the waste we make and the way we get around, we are always striving to act in the most responsible way possible for our planet. We actively seek ways to reduce waste and enable customers to have more sustainable options on their property. As our work inevitably does involve some hardware, transport and even a digital footprint, we offset our carbon emissions through the Ecologi tree planting programme.
