Why Should a BS3036 Consumer Unit Be Upgraded?

If your fuse box still has BS3036 rewireable fuses (the old-style ones with fuse wire), it’s a sign that your electrical system is out of date – and may not offer the protection modern homes need.
Here’s why it’s worth upgrading:
So, why should a BS3036 consumer unit be upgraded... Slower fault response – Rewireable fuses take longer to disconnect in a fault, which can increase the risk of fire or electric shock.
No RCD protection – These boards don’t include RCDs, which are essential for protecting you from electric shock.
Hard to maintain – You have to replace fuse wire manually if it blows, which isn’t ideal – especially in an emergency.
Not suitable for modern demands – Today’s homes have far more electrical devices than when these boards were designed.
Upgrading to a modern consumer unit with MCBs and RCDs (or RCBOs) gives you faster, more reliable protection, better energy efficiency, and peace of mind that your system meets current safety standards (BS 7671).
It’s one of the best things you can do to improve the safety of your home’s electrics.
An Introduction to Speller’s Sparks (Rich Speller)
I have had a varied career to date... before becoming an electrician I was a Head of Music in a Bristol Secondary School, indeed I have taught music and young people for the last 15 or so years prior to 2021. In 2021 I retrained and left teaching to be a full-time electrician, serving mainly domestic customers in your home... the kind of electrical work I specialise in ranges from smaller electrical works; so changing light fittings and installing, putting in new sockets and/or outdoor sockets (and everything in between!), I also upgrade a fair number of Consumer Units and complete bespoke EV installation!
I have three boys, whom I love very much (even though they may drive me around the bend now and then... and I live in Chilcompton but serve all surrounding areas, down to Wells, to Frome, parts of Bath and everywhere in between... you’ll often see me and my van (Bella 🐶) often sat in the front driving around Radstock, Midsomer Norton and Paulton!
What makes me different to other electricians in the area:
It’s just ME, it will be me that will be turning up to discuss your requirements and complete the work and providing you with all the required paperwork
As a small business you will get a far more personalised approach, I am friendly and will be happy to answer any questions you have before, during and after the work is complete... if you’d just like a natter about the state of the world we can do that too 🙂
I am registered & qualified with professional bodies such as NAPIT and Trustmark, I am also a Which? Trusted Trader... and you can only get these accreditations when you have certain safeguards in place i.e. customer complaints process, appropriate insurances etc
I have 5* testimonials from other customers in the area for your peace of mind - including on Facebook and Google and this is not only because I complete work to the highest of standards but I will provide you with excellent support after the work is done - even if it’s just to recommend another local business or trade!
