Panel Upgrade in Brentwood, UK
A 200-amp panel upgrade in Brentwood involves replacing your electrical service entrance, installing a new main breaker panel, utility coordination (your local utility requires a temporary disconnect), and a city electrical inspection before the utility reconnects service. Plan for 1–2 days of work plus 2–6 weeks for utility scheduling.
A licensed electrician handles all panel work. The permit process in Brentwood typically adds $200–$500 to the project cost but is non-negotiable — unpermitted panel work creates serious insurance and resale liability.
A straightforward 200-amp upgrade in Brentwood costs $1,500–$5,500 in most markets, $2,000–$7,000 in high-cost metros like LA and NYC. Homes that also need a meter socket upgrade or service entrance cable replacement add $500–$1,500. Budget higher if your panel is in a difficult location or if the utility requires a weatherhead replacement.
All contractors in the Brentwood network are licensed through TrustMark-registered and Which? Trusted Trader-accredited roofers and carry full general liability and workers' compensation insurance.

Brentwood experiences strong winds, heavy rainfall, frost, freeze-thaw cycles and flooding — hiring a locally-experienced contractor is essential.

How Panel Upgrade Works in Brentwood
What to expect from a licensed Brentwood electrician from first call to completion.
- 1
Load Calculation
The electrician calculates your home's total load to confirm the right amperage (100A, 200A, or 400A) and identify any circuits that need to be reconfigured.
- 2
Permit Application
A permit is required for all panel work. The electrician submits the permit and schedules both a utility disconnect and a city inspection.
- 3
Panel Replacement
Utility disconnects the service. The old panel is removed, the new service entrance and main breaker are installed, and all circuits are reconnected and labeled.

Surge Protection & Grounding
A whole-home surge protective device (SPD) is installed as required by NEC 2020. Grounding and bonding are verified and updated.

Inspection & Sign-Off
The city inspector verifies the installation. Utility reconnects service after the inspection passes. Final load test confirms all circuits are functional.

Only electricians certified under Part P Building Regulations (NICEIC, NAPIT, or SELECT-registered) can legally perform this work. Unpermitted electrical work voids your home insurance, creates fire hazards, and triggers costly fines or forced remediation when discovered during home sales.

A 200 amp consumer unit (fuse board) upgrade in Brentwood costs £1,500–£3,500 installed, including permit, inspection, and utility coordination.

What is aluminum wiring and is it dangerous?
Aluminum branch circuit wiring installed in homes built between 1965–1973 is a fire hazard. Aluminum expands and contracts differently than copper, creating loose connections that overheat and ignite insulation. Many older Brentwood homes contain this wiring. Remediation involves either pigtailing (copper connections at outlets) costing £500–£1,500, or full rewire at £4,000–£8,000. A licensed electrician inspection identifies aluminum wiring quickly. ProvenQuote connects you with specialists in ENG.
