UK monitored alarm comparison

ADT vs Verisure

Two professionally installed, human-monitored security services compared on the terms that matter after the sales visit—not just the equipment shown in the demonstration.

Provider information checked: 30 August 2026
Short answer: both offer professionally installed systems with ongoing monitoring and maintenance. ADT publicly emphasises its NSI Gold-accredited installation and monitoring routes, including eligible police-response packages. Verisure emphasises its wireless system, SSAIB-certificated Alarm Receiving Centre, inclusive maintenance and private guard intervention. The better proposal depends on the written quote, response route, contract and equipment-ownership terms offered for your address.

Compare both quotations on one sheet

  1. Equipment and installation total
  2. Monthly monitoring and maintenance
  3. Minimum term and renewal basis
  4. Annual price-adjustment clause
  5. Cancellation notice and exit charges
  6. Equipment ownership after cancellation
  7. Alarm-verification procedure
  8. Police, keyholder or guard response
  9. Call-outs, batteries and replacement parts
  10. Moving-home or transfer costs
Do not compare only the monthly figure. A lower monthly quote can still cost more once the installation payment, minimum term, annual increases, maintenance tier and equipment status are included.
