RCBO Protection

If you’re wondering about the cost of a replacement fusebox in Milton Keynes, you’re not alone. A modern consumer unit is essential for keeping your home safe, compliant, and running efficiently. Whether you're dealing with frequent tripping or an outdated board - knowing what’s involved, and how much it costs, is key.

In this guide, we will explore the reasons for replacement, what goes into a consumer unit upgrade, and the costs you can expect. Our goal is to make this process less overwhelming and more informative, helping you make confident decisions about your home’s electrical safety when considering a consumer unit upgrade in Milton Keynes.

Top Reasons to Replace Your Fusebox in Milton Keynes

Before discussing costs, let’s look at why you might need to replace your fusebox.

Outdated Units

Many older homes may still be using outdated fuseboxes. For example, units manufactured before 2000 often lack essential safety features present in modern systems such as RCD protection and surge protection. If your fusebox is more than 20 years old, it may be time for an upgrade.

Lack of RCD Protection

Residual Current Devices (RCDs) are vital for electrical safety. They help prevent electric shocks and decrease the risk of fire. If your current fusebox does not have RCD protection, it is crucial to replace it.

Frequent Nuisance Tripping

If you currently have a split load fusebox with one or two RCDs supplying multiple sockets you may be experiencing nuisance tripping. Frequent tripping can disrupt your daily routine and interrupt your work if you work from home. Homeowners should keep track of these incidents, as more than three trips a month often indicate an underlying issue. Upgrading to an RCBO consumer unit can significantly reduce nuisance tripping and avoid irritating disruptions by giving each individual circuit its own RCD protection via RCBOs - a key feature of an 18th Edition consumer unit upgrade.

Compliance with Regulations

Electrical regulations evolve over time. Upgrading to a modern 18th Edition consumer unit ensures compliance with the latest safety standards. Not only does this keep your home safe, but insurers often require compliance for cover, especially in high risk buildings such as thatched properties.

Benefits of a Modern Consumer Unit (Fusebox Upgrade)

The benefits of updating your fusebox, also known as a consumer unit replacement, extend beyond mere appearance:

✅ Improved Safety

Modern consumer units provide advanced safety features. For example, they come equipped with RCDs/ RCBOs and circuit breakers that minimize the risk of electric shocks and fires. They are also metal clad, supporting the cables in the event of a fire to prevent them blocking crucial escape routes, making your home considerably safer.

✅ Compliance

Upgrading guarantees that your system adheres to current regulations. This is especially important for Landlords since the changes to electrical safety regulations in June 2020 requiring mandatory electrical safety checks by local qualified electricians.

✅ Increased Property Value

Renovating electrical systems can enhance your property’s market value. Future buyers usually prefer homes with modern safety features.

✅ Peace of Mind

Knowing that your home is equipped with the latest in electrical safety technology can significantly reduce any worries about electrical hazards.

How Much Does It Cost to Replace a Fusebox in Milton Keynes?

What’s the Average Cost to Replace a Fusebox in the UK?

The cost to replace your fusebox in the UK varies, but in Milton Keynes, homeowners typically spend between £600 and £1500 for an 18th Edition consumer unit upgrade, though several factors can influence the final price:

Additional Faults or Non-Compliances

During the replacement, if any faults or DIY electrical work are discovered, these can lead to extra costs. You can mitigate this unexpected cost by having an EICR carried out prior to the fusebox replacement.

EICR Costs

Getting an Electrical Installation Condition Report (EICR) can be beneficial before installation. While this introduces an additional cost, averaging around £200-£300, it helps identify potential issues for a smoother installation process.

Number of Circuits

Most of the cost variation comes down to the number of circuits on the existing fusebox, this can typically range from as little as 5 circuits up to 20+, with each RCBO costing £15-£25 and the extra labour involved, extra circuits can soon add up.

AFDDs

Arc Fault Detection is a hot topic in the electrical industry following the Grenfell Tower fire in 2017. AFDDs (Arc Fault Detection Devices) are now required in some high-risk residential and commercial buildings. While optional in most homes, they can provide added fire protection. Discuss this with your electrician - but be aware they can add £70-£100 per protected circuit in your new upgraded 18th edition consumer unit.

Summary of Costs

While standard consumer unit replacements in Milton Keynes range from £600 to £1500, a detailed quote from a Part-P approved local electrician such as MK Sparks will provide a precise cost based on your specific needs.

EICR: To Get or Not to Get?

✅ Pros of an EICR

• Identifies Issues: An EICR supplies a thorough assessment of your electrical system. It reveals existing faults, allowing for proactive corrections.

  
  

• Peace of Mind: Knowing potential issues beforehand can help you budget and prepare for necessary upgrades, making the process smoother.

  
  

❌ Cons of an EICR

• Upfront Cost: The EICR comes with its own cost but is usually worthwhile in the long run.

  
  

• Time Consumption: Waiting for the report can delay the fusebox replacement, extending your project timeline.

• Depends on the scope of other work: If you are carrying out a major renovation that includes significant rewiring, an EICR might be redundant.

  
  

Summary on EICR

Despite the pros and cons, obtaining an EICR is generally a smart move. It can save you significant hassle and expenses by tackling issues upfront.
