Your consumer unit is at the heart of your home’s electrical installation, providing protection for the circuits, wiring and ultimately the people living within the property.

If your home still has an older fuse box, outdated protective devices or limited RCD protection, upgrading to a modern consumer unit can significantly improve the electrical safety and protection within your home.

At HB Electrical, we install high-quality modern consumer units throughout Bristol, carefully selected and configured around the requirements of each individual property.

A consumer unit upgrade shouldn’t simply involve removing the old box and replacing it with a new one.

Before carrying out an upgrade, it’s important to understand the condition of the electrical installation connected to it.

Older wiring, existing faults, poor alterations or previous DIY electrical work can all become apparent when modern protective devices are installed.

That’s why we take the time to assess and test the existing installation, identifying potential issues and making sure the proposed upgrade is appropriate for your home.

If problems are discovered, we’ll explain them clearly and discuss the available options before proceeding.

Electrical safety technology has moved on considerably from the traditional fuse boxes still found in many older Bristol homes.

Using individual RCBO protection means a fault on one circuit is less likely to unnecessarily disconnect other circuits within the property.

Depending on your property and installation, a modern consumer unit can incorporate features such as:

There are significant differences in the quality of consumer units and protective devices available.

At HB Electrical, our focus isn’t on installing the cheapest possible equipment.

We use high-quality components from established electrical manufacturers and install them carefully, neatly and with consideration for the long-term reliability of the electrical installation.

A consumer unit may spend most of its life hidden away in a cupboard, but that doesn’t mean the workmanship inside it should be any less important.

The details matter — especially when it’s equipment designed to protect your home.

Having an older fuse box doesn’t automatically mean your entire electrical installation needs replacing.

However, it may be worth considering an upgrade if your property has:

If you’re unsure, we can inspect your existing installation and advise whether an upgrade is necessary or worthwhile.

For older properties, we can also combine your consumer unit upgrade with a more comprehensive electrical inspection or EICR.

This gives us an opportunity to properly assess the condition of the circuits connected to the new equipment and identify any defects or areas that may benefit from improvement.

We would rather give you an honest understanding of the installation than simply fit a new consumer unit and ignore problems elsewhere.

HB Electrical works across a wide range of electrical installations.

Alongside domestic consumer unit replacements, we can also carry out distribution board upgrades for commercial and larger electrical installations, including projects where work needs to be carefully coordinated to minimise disruption.

For businesses where isolation during normal operating hours isn’t practical, out-of-hours electrical work can also be arranged.

Whether you’ve recently purchased an older property, your existing fuse box is showing its age, or you’re planning electrical improvements that require modern protection, we can assess your installation and recommend the right solution.
