Fuse Box &  Consumer Unit Replacement

Update your fuse box so your electrics keep working safely and meet the latest regulations.

Meet the latest regulations with a fuse box replacement

Having an up to date fuse box (consumer unit) is a major part of ensuring your electrics are safe and up to standard. All of our installations are fully certified and we’ll even notify your building control. We’ll test all the electrical circuits in the house during the installation, which will confirm the whole house is electrically safe.

Why your home may need a fuse box (consumer unit) replacement

A fuse box and a consumer unit serve the same purpose. They distribute electricity in your house through multiple circuits and instantly turn the power off whenever a power overload occurs on one of the circuits, which is commonly known as “tripping”.

When “tripping” occurs, a consumer unit will switch the power off using the circuit breaker linked to the overloaded circuit. It will turn itself to the position OFF making the faulty circuit easily identifiable. Once the circuit is fixed, the circuit breaker can be switched back on and the power restored.A fuse box uses fuses instead of circuit breakers. Each fuse contains a wire which will melt if there is an electrical overload and make the circuit trip and switch the power off.

It is not as easy to identify a faulty circuit when using a fuse box and the, now melted fuse, will need to be replaced before the power can be restored.
Consumer units are basically the modern and safer version of fuse boxes which in most cases are no longer compliant with current electrical regulations.

Frequently Asked Questions

Electric installation such as the replacement of a fuse box should be done by qualified individuals who are able to issue a certificate for the installation in accordance with Building regulations. In this instance a qualified electrician is your best option.

Consumer units boxed in wooden cupboard or mounted under wooden stairs are seen as a fire hazard as these materials are highly combustible.
According to building regulations your consumer unit should be enclosed in a cabinet or enclosure constructed of non-combustible material such as steel.

According to regulation, gas pipes and gas meter in domestic houses, must be spaced at least 150mm from electricity meters, switchboards, electric cables, sockets, telecommunication cables, consumer units and any other conductors. Additionally, there should be a separation between a supply or distribution cable of at least 25mm for domestic pipework up to 35mm or 50mm for pipework over 35mm.

Before fitting a shiny new electrical consumer unit, it is advised to carry out an electrical Installation condition report (EICR). This test will establish the health of the electrical installation in your house and enable you and your electrician to decide if the existing wiring and circuits are fit for purpose.

The time it takes to replace a fuse box may vary on the size of the property as well as the conditon of the exsiting wiring. A typical replacement geneally takes around half a day.

No, old fuse boxes are not illegal. However, if you do have an old fuse box in your property please consider health and safety. It might not be compliant with current regulations and won’t have the latest RCD protection which could save your life. Consider upgrading it to a newer model.

Dean and his team recently completed a full re-wire of our house. Communication was excellent throughout; he worked with us to clarify our expectation and specifications, and ensured we were aware of associated costs and trade-offs. Yes, we had a few minor snags, but nothing major and issues were sorted very quickly. Furthermore, Dean offered options we had not considered or thought about from a practicality perspective which added value to our re-development. We've enjoyed working with Flow, and would not hesistate to use them again!

Thank you Dean for answering my call for help Friday evening. Your time in talking through the problem which solved some of the trouble, phoning Saturday to check if we had electricity and coming Monday to confirm the problem, all done with a smile. No other work needed but will definitely keep Flow Electrics on my contact list for the future if we need an Electrician

I've been using Flow Electrics now for a little over 2 years.They have done a huge amount of work for us, including re-wiring an old cottage during renovations, more downlight replacements than you could shake a stick at, exterior lighting installation and many many other projects.The guys have always been on time, incredibly nice, very professional and brilliantly priced. Have always cleared up after themselves and never failed to do a brilliant job.Great company - would highly recommend to all.

I am the Chairman of Southwater football club and we have approx. 200 players which age ranges from 4 years old right up to mid 50s who play for our club. During the winter months we need our portable floodlights to work to ensure the players can train, these floodlights where becoming very troublesome and we would always seem to struggle to have enough working to enable a full training session. I decided it was time to get the experts in to fix once and for all. Dean and his team came to the rescue that same day, fixed 2 of them and rewired the others by correcting the design faults and making them useable for the foreseeable future. Dean was honest about costs and how easy the parts are to get, which allowed me to make some decisions on whether to fix all or not. Great knowledge and would definitely use them again, thank you

Dean and his team made a great job of installing new cabling between my house and garage so that the increased load of the charger would keep tripping the house RCD's. Every thing is hidden or neatly pinned to the wall with an eye for detail. Dean fits the Sync EV charger, which is the smallest on the market, neat and unobtrusive. It's also locally made in Sussex. After the installation, Dean commissioned the unit to ensure it was working and then handled the Government grant application. A great company, wholly recomended.

Best Electrician in Burgess Hill and probably all of Sussex. If you are getting any kind of electrical work done at your property, then do yourself a favour and make sure you get quote from Dean and his team at Flow Electrics LTD.In September 2020 Flow Electrics LTD completed a full rewire at our 1930’s property in Burgess Hill. The work was completed on schedule, and to an extremely high standard. Dean and his team are all capable professionals that are polite, knowledgeable, tidy and were a pleasure to have working at my property.Dean was generous with his knowledge and experience of having re-wired similar properties and challenged us (in a good way) to think about not only how we would be living in the property now, but also about the things we might need the electrical wiring to do in the future (allowing for an extension, etc…). As a result, we now have safe new electrics in our home and when we are ready to make it a bit bigger, then Deans future proofed planning will make adding an extension both easier and cheaper.However, what really motivated me to sit down and write this review, was that in addition to all the work you would think goes into rewiring an old property – Dean has also provided us with an impressively high standard of care. Right from our first meeting, Dean was always happy to give advice and make recommendations. I got the feeling that he took a genuine interest in our property and us; listening to him talk about all the different options and opportunities he felt that we had, you would be forgiven for thinking that he was discussing the improvements he would want to make to his own home. Dean is clearly proud of the work he does for every customer and this professionalism inspires confidence.Dean has (and has continued to) look after us as our electrician. So, if you need a skilled expert to look after any electrical issue at your property, then I whole heartedly recommend Dean and his company Flow Electrics LTD.
