Rankings are based on review rating and review count from public business listings, with a small lift for businesses that show a working website and phone number. We check each business's homepage to confirm alarm and security installation is what they primarily offer, which keeps unrelated trades off the page. Listings marked as permanently closed are removed automatically. Businesses displaying a Trust Verified badge 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 here haven't been independently verified by us, and appearing on this page isn't an endorsement. Always carry out your own checks before hiring.
