Rankings are based on review rating and review count from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm electrical work is what they primarily do, which keeps unrelated trades off this page. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information, see our How We Verify page for the complete list. Other businesses have not been independently checked by us, and their inclusion here isn't an endorsement. Always do your own checks before hiring.
