- Switchboard Upgrades
Your switchboard (sometimes called the consumer unit or fuse-box panel) is the heart of your home’s electrics. If it’s outdated, overloaded or lacks modern safety features, you could be exposing your property – and your family – to unnecessary risk. At 12 Electrical & Emergency Electrician Ltd, we offer professional switchboard upgrade services for homeowners across South Wales, Bristol, Gloucester, Cheltenham and Weston-super-Mare. Our certified engineers will bring your system up to modern standards, improve capacity, and future-proof your electrics.
Do you need a switchboard upgrade?
If your home still uses old ceramic fuses, has a fuseboard without Residual Current Device (RCD) protection, or frequently trips circuits whenever you switch on modern appliances, there’s a good chance your switchboard needs attention.
Upgrading the switchboard involves replacing the outdated board with a modern consumer unit fitted with circuit breakers, RCDs, surge protection and – in some cases – increased capacity to handle today’s high-demand devices and systems. Not only does it enhance safety and compliance, but it also gives you the flexibility to install future upgrades like EV chargers, solar panels or home automation.

- Capacity upgrade & future-proofing – If your home is being renovated or you’re adding significant new load (kitchen extension, EV charger, basement, etc.), we’ll upgrade the panel to cope with modern demands.

Frequentkly Asked Questions
How do I know if I need a switchboard upgrade?
Look out for frequent circuit breaker trips, flickering or dimming lights when several devices run, old ceramic fuse boxes, buzzing or hot switchboard panels – all are strong indicators an upgrade is needed.
How long does a switchboard upgrade normally take?
For a typical domestic upgrade it might take around 4-8 hours, depending on the property size and how much rewiring is needed.
Will I need to switch off my power during the upgrade?
Yes – the mains supply will need to be turned off while the switchboard work is carried out to ensure safety. We’ll plan the timing with you and aim to minimise downtime.
Does upgrading the switchboard add value to my home?
Definitely. A modern compliant switchboard increases safety, improves capacity, supports future tech (EV charger, solar) and is a strong selling point when you come to sell or insure your home.
What happens if I ignore a faulty or outdated switchboard?
You risk more than just nuisance tripping circuits – there’s a higher chance of electrical faults, fire risk, potential failure of safety protection (like RCDs) and non-compliance with regulations which may affect insurance cover.
