Many accidents at home are caused by faulty wiring or old installations. Organisations such as Electrical Safety First provide independent advice to help homeowners stay protected and aware of the risks.

Common Questions from Homeowners

Here are just some of the topics we cover in our guides:

When does my fuse box need upgrading?
Modern consumer units are safer, faster, and meet today’s electrical regulations. If your fuse board is old or uses rewireable fuses, it may be time to consider an upgrade.
How do I know if my house needs a rewire?
Flickering lights, discoloured sockets, or constant tripping are signs that your wiring may be past its best. Our post on 5 Signs Your Home Needs a Rewire explains what to look out for.
Can I save money with energy-efficient lighting?
Yes. Switching to LED lighting or installing smart lighting controls can cut running costs and create a more comfortable home. Our energy saving guides break down the options for you

It's so rare for an electrician to turn up promptly at a pre-arranged time and this is the second time that APP have done so.
They worked until after 7pm in order to finish the job on the same day

APP rewired my tv and and electric curtains with new sockets etc. Shaun and Lewis were polite and worked hard, tidying up well afterwards. They explained what they had done clearly and what is going to happen next. I would highly recommend them.

First time renovating a home and first time using electricians. We booked APP through our carpenter, who recommended using them when completing our kitchen fitting.

Had Andy to come and do the quote. Then had the pleasure of Connor and Owen doing the first fix, and Owen and Sean for the second fix. What a great bunch of guys they all are! They were all super friendly, knowledgable, professional and helpful. They've done a great job installing new lights, sockets, oven, dishwasher, induction hob and fuse box. I can't thank them enough for all their hard work- completed to a great standard. Owen also came out to check something before the quartz was fitted, and then the company arranged for the second fix to be completed sooner. Meaning we could use the appliances and cook food much sooner than we expected.

Also massive thanks to Sarah who kept up updated along the way.

Would definitely recommend this company and would use them again in the future. Thank you guys!!

Andy came out really quickly to quote on a job. I was having a full renovation and he was very accommodating in working with the other trades people. He also advised that the lights I bought were not suitable for safety reasons and was able to advise what I should be purchasing. Id recommend Andy to anyone looking to get electrical work done. Thanks
