McMillan Electrical has been upgrading consumer units and replacing fuse boards across Crawley for nearly two decades. Whether you're in a post-war home in Northgate or Three Bridges, a family property on Pound Hill or Maidenbower, or a business on Manor Royal, our NICEIC-approved team ensures your electrical installation meets current 18th Edition standards.

As one of West Sussex's largest towns, Crawley's housing spans from its earliest New Town builds of the late 1940s through to the most recent development at Forge Wood — and that breadth of age and construction means we come across every type of consumer unit on every job.

Consumer Unit Upgrades for Crawley Homes and Businesses

A consumer unit upgrade replaces your existing fuse box with a new, fully 18th Edition compliant board — typically fitted with individual RCBO protection on every circuit and a Type 2 Surge Protection Device. The result is a safer, smarter installation that protects your circuits independently — so if one trips, the rest of your home stays live.

Most upgrades are completed in a single day. We isolate your supply, fit the new board, test every circuit, and issue your Electrical Installation Certificate before we leave — your legal proof of compliance under Part P of the Building Regulations. As your local NICEIC electrician in Crawley, we handle every step of the process, from the initial assessment through to certification.

Why Crawley Homes Need Consumer Unit Upgrades

Crawley is unique among the towns in our service area — it was purpose-built as a New Town from 1947 onwards, which means its housing stock has a very distinct age profile. The original neighbourhoods built through the late 1940s and 1950s — West Green, Northgate, Three Bridges, Langley Green, and Ifield — are now approaching 70 to 80 years old. Consumer units in these areas are frequently original or only partially updated, and rarely meet current 18th Edition standards. The neighbourhoods built through the 1960s and 70s — including Tilgate, Gossops Green, Broadfield, and Bewbush — are not far behind, and we regularly find boards in these areas that need full replacement.

The more recently developed areas — Pound Hill, Furnace Green, Maidenbower, and Forge Wood — are generally better specified, but even 1990s consumer units are now old enough to require an SPD fitted under Amendment 2, and many no longer have the capacity for modern demands like EV chargers and home office circuits. We also work regularly with businesses on Manor Royal, Crawley's large industrial and commercial estate, where distribution boards and consumer units need to meet current standards.

Consumer Unit Replacement Cost in Crawley

Consumer unit upgrades in Crawley start from £700 + VAT (£840 inc VAT) for a standard domestic property, rising from £1,000 + VAT (£1,200 inc VAT) for larger or more complex installations.

Every upgrade is the same full specification — an 18th Edition compliant board with individual RCBO protection on every circuit, a Type 2 Surge Protection Device, and a full EICR on your installation, so you get a written assessment of the whole property alongside the new board.

We always provide a written, fixed-price quote after a free site visit, so the consumer unit replacement cost you're given upfront is exactly what you'll pay. For a full breakdown of pricing across all job types, see our consumer unit upgrade cost guide.

Consumer Unit Upgrade FAQs — Crawley

Everything you need to know about consumer unit upgrades across Crawley
and the surrounding areas.

Do you cover all of Crawley's neighbourhoods?

Yes. We carry out consumer unit upgrades across all of Crawley's 14 neighbourhoods — from Northgate and Three Bridges through to Maidenbower and Forge Wood — as well as businesses on Manor Royal.

My home was built in the 1950s or 60s — does it definitely need a consumer unit upgrade?

Not necessarily — but it almost certainly warrants an assessment. Properties built during Crawley's New Town development era frequently still have original or partially updated consumer units that don't meet current 18th Edition standards. An EICR will give you a definitive answer, and we can carry out both the inspection and any upgrade required.

Do you carry out consumer unit upgrades for businesses on Manor Royal?

Yes. We regularly work with businesses across Manor Royal, upgrading consumer units and distribution boards to ensure compliance and support growing power demands. Commercial work is carried out with minimal disruption to your operations.

Can I get a combined consumer unit upgrade and EV charger installation in Crawley?

Yes. If your existing board doesn't have the capacity or compliance required for an EV charger, we can carry out both jobs in a single visit — assessing the board, upgrading where needed, and installing the charger on the same day.

Consumer Unit Upgrades Across Crawley's Neighbourhoods

Northgate, Three Bridges & West Green

Crawley's earliest New Town neighbourhoods, built from 1949 onwards. Properties here are among the oldest in the town and frequently still have the original consumer units from their construction era. We regularly carry out full board replacements in this part of Crawley.

Tilgate, Gossops Green & Broadfield

Built through the 1950s, 60s and 70s, these established neighbourhoods contain a mix of ex-council and private properties. Consumer units in this age bracket often pre-date the introduction of RCD protection and are well overdue for an upgrade.

Pound Hill, Maidenbower & Furnace Green

Crawley's eastern and more recently developed neighbourhoods. Maidenbower dates from the late 1980s and 90s and is generally well specified, but many properties here still need a Surge Protection Device added to meet current 18th Edition Amendment 2 requirements.

Manor Royal Business District

One of the South East's largest business parks, home to hundreds of commercial and industrial units. We carry out consumer unit and distribution board upgrades across Manor Royal for businesses of all sizes — keeping premises safe, compliant, and capable of meeting growing power demands.

We're proud to help keep Crawley's homes and businesses — from its oldest New Town properties to its newest developments — safe, compliant, and properly protected.
