Project Overview
As part of a full electrical refurbishment at a property in Rushden, Northamptonshire, we replaced an ageing consumer unit that had been in service for around 20 years.
The existing board had served the property for a long time, but electrical safety standards, protective devices and the way homes are used have changed considerably over the past two decades. Modern properties now rely on far more sensitive electrical equipment, from broadband routers and smart devices to kitchen appliances, heating controls, home offices and entertainment systems.
Rather than reconnecting newly upgraded wiring into an older board, the customer chose to invest in a modern consumer unit that would provide better protection for the property and the people living there. That decision also gave the finished refurbishment a stronger long-term foundation.
The installation was upgraded to a new Niglon consumer unit fitted with individual RCBO protection on every circuit, together with an integrated Type 2 Surge Protection Device. The finished installation was fully inspected, tested and certified before being handed back to the customer.
The Existing Consumer Unit
The original consumer unit had reached the point where replacement was the most sensible long-term option. It was not simply a case of changing equipment for the sake of appearance. During a refurbishment, the consumer unit becomes the central point for all the upgraded circuits, so it needs to be suitable for the work being carried out and appropriate for future use.
Older consumer units can still appear to operate normally while lacking many of the protective features now expected in a modern domestic installation. Common limitations include no individual RCBO protection, no surge protection, more limited fault discrimination, less clear circuit identification and reduced flexibility for future electrical additions.
For this Rushden property, replacing the consumer unit meant the new and existing circuits could be terminated into a board designed for current expectations rather than relying on equipment already approaching the end of its practical service life.
The Upgrade
For this project we installed a new Niglon metal consumer unit with individual RCBO protection across the circuits. The board was fitted with a Type 2 Surge Protection Device, neatly labelled and tested as part of the overall electrical refurbishment.
- New Niglon metal consumer unit
- Individual RCBO protection for every circuit
- Integrated Type 2 Surge Protection Device
- Clearly labelled circuits for easier identification
- Full inspection, testing and certification
- Electrical Installation Certificate issued on completion
Each circuit now benefits from its own RCBO. Unlike older split-load consumer units, where one fault can disconnect several circuits at once, RCBO protection isolates the affected circuit individually. That makes future fault finding more straightforward and helps reduce unnecessary disruption elsewhere in the property.
Why RCBO Protection Matters
A modern RCBO combines overload, short-circuit and earth fault protection into one device. In practical terms, that means each circuit has dedicated protection instead of relying on a shared RCD to protect a group of circuits.
This can make a real difference in day-to-day use. If a fault develops on one circuit, such as a socket circuit or lighting circuit, the RCBO for that circuit can trip without disconnecting unrelated parts of the property. For homeowners, that usually means less disruption, easier diagnosis and a clearer indication of where the issue is likely to be.
For electricians, individual RCBO protection also gives a cleaner and more logical installation to inspect and maintain. When combined with proper circuit labelling and test results, it helps make the electrical system easier to understand for future work.
Surge Protection for Modern Homes
The new consumer unit also includes Type 2 surge protection. A Surge Protection Device helps protect connected electrical equipment against transient overvoltages, which can be caused by events such as network switching or nearby lightning activity.
That matters because modern homes contain a growing number of sensitive electronic items. Televisions, computers, gaming consoles, smart home equipment, broadband routers, heating controls, appliance electronics and other devices can all be vulnerable to voltage spikes.
Surge protection is not a magic shield against every possible electrical event, but it is an important layer of protection in a modern installation. Including it as part of the consumer unit upgrade was a sensible decision for a refurbished home that will continue to rely on electrical and electronic equipment for years to come.

Why We Recommended Replacement
Because we were already carrying out a wider electrical upgrade at the property, replacing the consumer unit made practical and financial sense. Keeping an older board would have meant connecting upgraded wiring into equipment that was already around 20 years old.
Installing a modern RCBO consumer unit allowed the refurbished electrical installation to benefit from current protection standards from the start. It also reduced the likelihood of the customer needing another disruptive board replacement shortly after the refurbishment was complete.
This is often the key point with consumer unit work. The best option is not always the cheapest short-term route. The right decision depends on the age and condition of the existing board, the wider work being carried out, the number of circuits, available space, test results and how the property is likely to be used in future.
Testing, Certification and Handover
A consumer unit replacement is not just a physical board swap. The installation must be inspected and tested so the circuits connected to the new board are safe to energise and suitable for continued use.
On this Rushden project, the work included inspection, testing and certification on completion. Circuit labelling was also completed so the homeowner has a clear reference for what each protective device controls.
Clear documentation matters. It gives the homeowner a proper record of the work, supports future maintenance and helps avoid guesswork if additional electrical work is carried out later. It also gives a much better starting point if the property is sold, rented, extended or further upgraded in the future.
Consumer Unit Installations Throughout Rushden
Many homes across Rushden still contain consumer units installed 15 to 30 years ago. Some are still functional, but they may not provide the level of protection now available from a modern RCBO board with surge protection.
We regularly carry out consumer unit replacement work throughout Kettering, Rushden and nearby Northamptonshire towns. Whether your existing fuse board is outdated, you are renovating your property, or your installation has been identified during an EICR as needing improvement, we can advise on the most suitable route.
If you are looking for an electrician in Rushden, the first step is to assess the installation properly rather than assuming every property needs the same solution. Some boards need replacement because of age, condition or lack of protection. Others need further investigation first, especially where faults, nuisance tripping or poor circuit records are involved.
Why Choose Entigen?
At Entigen, we focus on carrying out electrical work properly rather than taking shortcuts. Every consumer unit installation is completed with careful attention to detail, neat workmanship and comprehensive testing before being placed into service.
Our goal is not simply to replace a fuse board. It is to leave the customer with an electrical installation that is safer, more reliable and easier to understand. That means using appropriate components, explaining the work clearly, testing thoroughly and giving honest advice about what is necessary for the property.
You can see more completed examples in our Our Work section, or contact Entigen if you would like advice about replacing an older consumer unit in Rushden or the surrounding area.
Thinking About Replacing Your Consumer Unit in Rushden?
If your consumer unit is over 20 years old, you are renovating your property, or you have recently received recommendations following an Electrical Installation Condition Report, replacement may be worth considering.
We will assess your existing installation, explain the options clearly and provide honest advice on whether a new consumer unit is the right solution for your home. Where replacement is recommended, the work is carried out by qualified electricians with the correct inspection, testing and certification completed before handover.
