Consumer Unit Upgrades — Horley

Fuse Box Replacement in Horley, West Sussex

Green Earth Sussex provides professional consumer unit upgrades across Horley and the surrounding areas of West Sussex. If your property still has an old-style fuse box with rewirable fuses, no RCD protection, or a plastic enclosure, upgrading to a modern consumer unit is one of the most important safety improvements you can make.

Horley sits on the Surrey-West Sussex border, close to Gatwick Airport, with a mix of post-war housing, modern developments, and established residential areas. Many Horley properties, especially those built in the 1950s–1980s, still have original fuse boxes that lack modern RCD protection. Whether you live near the town centre, in one of the newer estates, or in the surrounding villages, our NAPIT-approved electricians provide fast, certified consumer unit upgrades across the Horley area.

Our NAPIT-approved electricians complete most Horley consumer unit upgrades in a single day. Every installation includes full circuit testing, clear labelling, and an Electrical Installation Certificate. We also handle landlord upgrades, pre-sale replacements, and safety upgrades ahead of EV charger or solar installations.

Signs You Need a Consumer Unit Upgrade in Horley

If you recognise any of these signs in your Horley property, it's time to upgrade your fuse box.

Old Rewirable Fuses

If your Horley fuse box still uses fuse wire that you have to replace when it blows, it is well past its safe service life and should be upgraded immediately.

No RCD Protection

Modern consumer units include RCDs that cut power in milliseconds if there's a fault. If your Horley fuse box lacks RCD protection, you are not protected against electric shock.

Frequent Tripping

If your fuse box trips regularly, it may indicate overloaded circuits, a faulty unit, or wiring problems that need professional investigation in your Horley property.

Plastic Enclosure

Plastic consumer unit enclosures are no longer compliant under BS 7671 Amendment 3 (2015). If your Horley fuse box has a plastic back, it needs replacing with a metal-clad unit.

Over 25 Years Old

Consumer units have a typical lifespan of 20–25 years. If your Horley fuse box is older than this, it likely lacks modern protection and may have deteriorated internal components.

Selling or Renting

Many insurance companies and mortgage lenders now require modern consumer units. If you are selling or renting your Horley property, upgrading the fuse box is often essential.

Consumer Unit Upgrades Horley — FAQs

Common questions from Horley homeowners about consumer unit upgrades, fuse box replacements, and electrical safety.

How much does a consumer unit upgrade cost in Horley?
Consumer unit upgrade costs in Horley depend on the size of your property and the type of unit. For a typical 2-bedroom house, expect £500–£700. A 3-bedroom house costs £600–£850. A 4-bedroom or larger property costs £750–£1,500. RCBO upgrades (individual protection on every circuit) cost £1,200–£1,800. All quotes are fixed-price and include the unit, installation, testing, and certification — call 01273 076860 for a free quote.
How long does a consumer unit upgrade take in Horley?
Most consumer unit upgrades in Horley take 3–5 hours for a standard domestic property. A 1-bedroom flat takes 3–4 hours. A 3-bedroom house takes 5–6 hours. Larger properties or HMOs may take a full day. Your power will be off during the installation, but we work efficiently to minimise disruption. We'll give you a clear time estimate before we start.
Do I need to rewire my house at the same time as upgrading the consumer unit in Horley?
Not necessarily. We can upgrade your consumer unit independently of a full rewire. However, we will test your existing circuits during the installation. If any circuits fail testing or show signs of deterioration, we'll advise you honestly. Many Horley homeowners upgrade their consumer unit first and plan a partial rewire later if needed. We never recommend unnecessary work.
Will I get an electrical certificate after a consumer unit upgrade in Horley?
Yes — you will receive a full Electrical Installation Certificate upon completion. This certificate is essential for insurance purposes, property sales, and rental compliance. For rental properties, the certificate forms part of your landlord safety documentation. We also notify building control where required under Part P of the Building Regulations.
What is the difference between a dual RCD and an RCBO consumer unit in Horley?
A dual RCD consumer unit splits your circuits across two RCDs — cost-effective but if one RCD trips, you lose multiple circuits. An RCBO consumer unit provides individual RCD protection on every single circuit — if one circuit trips, the rest stay on. RCBOs are the premium option and are increasingly recommended for modern homes, especially those with EV chargers, solar, or lots of electronics. We can advise which is best for your Horley property.
Is my old fuse box dangerous in Horley?
Old fuse boxes with rewirable fuses, no RCD protection, or plastic enclosures are no longer compliant with current BS 7671 wiring regulations. They lack the life-saving protection that modern consumer units provide. While not immediately dangerous in every case, they significantly increase the risk of electric shock and fire. If your fuse box is over 25 years old, has rewirable fuses, or no RCD protection, we strongly recommend upgrading — call 01273 076860 for a free assessment.
Do you install surge protection (SPD) with consumer units in Horley?
Yes — we can install Surge Protection Devices (SPDs) alongside your new consumer unit. Since the 18th Edition of the wiring regulations, SPDs are recommended for all new installations. They protect your sensitive electronics, appliances, and smart home devices from voltage surges caused by lightning strikes or grid switching. SPD installation costs £150–£250 as an add-on to your consumer unit upgrade.
Can you upgrade my consumer unit before I install an EV charger or solar panels in Horley?
Absolutely — and we often recommend it. EV chargers and solar inverters draw significant power and require a modern consumer unit with adequate capacity and RCD protection. We can assess your current setup, upgrade the consumer unit, and then install your EV charger or solar system. Many Horley homeowners combine these projects for efficiency and cost savings.
