The 2026 British Standard for anti-snap cylinders makes police data on forced entry obsolete
Lock snapping is a method burglars use to break a euro cylinder by applying force and twisting it in half. The Secured by Design (SBD) scheme, operated by the Police Crime Prevention Initiatives, states that over 20% of all burglaries involve lock snapping, with the majority occurring on UPVC doors (Secured by Design, 2026). From 2026, any new or replacement cylinder fitted to a security-rated door must meet TS 007 3-star or BS 8621:2024 standard.
Anti-snap cylinders cost £25-£70 fitted. From 2026, only TS 007 3-star or BS 8621:2024 cylinders meet the standard for security-rated doors. Check the star rating before buying.

- Only TS 007 3-star or BS 8621:2024 cylinders meet the 2026 standard.
- A 3-star cylinder resists snapping, drilling, picking, and bumping.
- A 1-star cylinder only passes the snap test, not drill or pick.

The key distinction is this: a 3-star cylinder resists snapping, drilling, picking, and bumping, while a 1-star cylinder only resists snapping. A 2-star cylinder sits in the middle, passing snap and drill tests but not the full pick test (GOV.UK, 2026). If you buy a cylinder labelled only “anti-snap” without a star rating, it almost certainly fails the 2026 standard for security-rated doors.
The two-part test what “anti snap” actually means in a 2026 cylinder
An anti-snap cylinder contains a sacrificial break line on the outside face. If an attacker snaps the cylinder, the internal locking mechanism remains engaged because the break line separates the outer section from the inner lock body. The British Standard TS 007 3-star rating requires the cylinder to survive a 3-minute snap test, a 5-minute drill test, and a 10-minute pick test (BS 8621:2024, British Standards Institution).
A 2-star cylinder, often sold as “anti-snap” in previous years, only passes the snap test and fails on drill or pick resistance. The TS 007:2022 standard, updated from the earlier 2012 version, now requires the drill and pick tests to be performed on the same cylinder sample, not separate samples (Loss Prevention Certification Board, 2026). This means a cylinder that passed the old test may fail the 2026 version.

Prices are from major UK DIY chains as of May 2026 (Screwfix, 2026). Fitting times are based on Master Locksmiths Association data for a standard UPVC door in good condition (Master Locksmiths Association, 2026).
Who qualifies for a 2026 anti-snap cylinder upgrade — the eligibility rules
The 2026 update applies to all new-build homes under Part Q of Building Regulations and to any replacement cylinder on a door that has a security rating (BS 7950, PAS 24, or SBD). If your door already carries one of those ratings, you must fit a TS 007 3-star or BS 8621:2024 cylinder when the old one is replaced (Building Regulations Part Q, HM Government).
Existing homeowners without a security-rated door are not legally required to upgrade, but insurers increasingly require TS 007 3-star cylinders for home insurance policies. The Association of British Insurers says that if your policy specifies “five-lever mortice deadlock” or “BS 3621” for a wooden door, a euro cylinder on a UPVC door must meet TS 007 3-star to avoid a claim being reduced (Association of British Insurers, 2026). Check your door leaf for a sticker or stamped mark on the edge of the door showing PAS 24 or SBD logo. If none exists, you do not qualify for a mandatory upgrade, but you can still choose to fit one.
The direct answer how to confirm your cylinder is genuinely anti-snap in 2026
Look for the TS 007 3-star or BS 8621:2024 Kitemark on the cylinder body itself, not just the packaging. The Kitemark must include the manufacturer’s logo and the standard number. A generic “anti-snap” label without a Kitemark does not meet the 2026 standard (BSI Group, 2026).
Use the online “Kitemark search” tool on the BSI Group website to verify a specific product code. If the cylinder does not appear in the search results, it is not certified. The GOV.UK guidance on building product compliance recommends checking the product against the manufacturer’s declaration of performance, which should list the standard and test results (GOV.UK, 2026).

How to verify your installer meets the 2026 certification requirement
For a cylinder replacement on a security-rated door, the installer must be registered with an approved competent person scheme: FENSA (for doors) or TrustMark (for general security work). The installer must also hold a current Master Locksmiths Association (MLA) or Secured by Design (SBD) accreditation for lock fitting (FENSA, 2026).
Check the installer’s FENSA or TrustMark registration number on the official register before paying. The MLA website provides a “Find a locksmith” search tool that shows accredited members in your area (Master Locksmiths Association, 2026). If the installer cannot provide a registration number or a valid MLA membership, do not proceed with the work. How to check your installer's FENSA registration
