How much does electrical panel installation cost in the UK?

Quotations vary based on existing infrastructure, cable routing, and local labour rates.

What affects the cost of electrical panel installation?

Main cost factors include: panel type and amperage rating, distance from supply point, existing wiring condition, number of circuits required, and whether rewiring is needed. Listed building restrictions, soil conditions affecting groundworks, and emergency call-out timing also significantly impact final pricing.

What does electrical panel installation service actually include?

Installation encompasses supply assessment, circuit design, consumer unit fitting, circuit breaker installation, earthing and bonding verification, cable routing and certification. Testing includes polarity checks, earth loop impedance tests, and insulation resistance measurements. Full Building Regulations certification documentation is provided upon completion.

What's the difference between consumer unit replacement and new panel installation?

Consumer unit replacement upgrades your existing distribution board with modern safety devices whilst keeping current supply arrangements. New panel installation involves completely new supply routing, earthing systems, and circuit design—typically required for extensions, rewires, or increased electrical demand.

What should I check before hiring an electrical panel installation provider?

Verify NICEIC, NAPIT, or SELECT registration—these guarantee certified electrician status and Building Regulations compliance. Request previous job references, insurance documentation, and written quotations. Confirm they'll provide certification and testing reports meeting current BS 7671 standards upon completion.

How long does electrical panel installation take to complete?

Consumer unit replacement typically takes one to two days, including testing and certification. Full new installations for extensions or rewires require three to five days depending on complexity and cable routing distance. Most work completes within one working week from start to final inspection.
