Extensions services

There’s a lot to think about with a new extension, but one of the most important is the electrical aspect. Our experienced electricians can help you decide on the style, number, and location of your new switches and sockets.

But there are other things to sort out, too.

With a new extension, you’ll need new electrical cables connected to your consumer unit, as well as vital circuit breakers. Our electricians will do all this work to ensure your entire electrical system works properly and you can enjoy your new space.

Can I use my existing electrical system for my new extension?

If you’re planning a new extension, you may be wondering if your existing electrical system can cope with the increased demands – or if you’ll need to install a separate system.
While it’s possible to extend the current system in some cases, it’s crucial to consider factors such as load capacity, safety regulations, and the overall electrical demands of your new space.

Residential Extensions FAQs

If you can’t find the answers you are looking for in our FAQs area please get in touch and we will be happy to help.

Can I carry out electrical work in my home extension myself?

It is strongly recommended that you hire a professional electrician for electrical work in your home extensions. Working with electricity requires specialized knowledge and skills to ensure safety and compliance with regulations. Attempting to perform electrical work without the proper qualifications is likely to be very difficult and also hazardous

How long does electrical work in an extension usually take?

The duration of electrical work in a domestic extension depends on various factors, including the size and complexity of the extension, the electrical requirements, and the condition of the existing electrical system. Simple projects may be completed in a few days, while more extensive work can take several weeks. Your electrician will be able to tell you more.

What do I need to consider when sorting the electrical work in my extension?

You’ll need to bear several things in mind before deciding on the work you need. This includes things like where you want sockets, switches, and lighting. It also includes assessing issues such as the power requirements you’ll need. And it makes sense to think ahead and future-proof your extension by thinking how the space may be used in the years to come.

Can electrical work in my extension impact my existing electrical system?

Yes, it’s possible. When you have electrical work carried out in your extension, it may need to be connected to your main electrical system. This might include redistributing the electricity load, or upgrading the system’s capacity to handle more power. It’s important to talk to a professional electrician who can check how it affects your existing electrical system and make any changes needed to keep everything safe and working well in your whole property.

How can I ensure my new extension is energy efficient?

To ensure energy efficiency in your extension, think about incorporating energy-saving measures such as LED lighting, smart thermostats, energy-efficient appliances, and good-quality insulation. Consulting with a company such as Hopkins Electrical that specialises in energy-efficient solutions will provide valuable guidance and help your maximise energy efficiency.

Residential Project

What our customers think

Placed an emergency call out with Hopkins Electrical as I had lost all power to my house. Chris turned up within 60 minutes of me placing the call and found that a rat had bitten through one of the cables. He made a temporary repair and then came back a couple of days later and replaced the fuse board and the cabling. Neat job, very professional and very reasonably priced.

Michael Underwood

Chris and his team talked us through the whole re wiring process and made sure we had enough sockets and switches in the right places before we started any work. They turned up on time and were very professional in their approach to out very large project. They were always easy to get hold of and would always offer good solutions to any problems we had with our build.
