What stamp must my bowls have for national competitions?

Question

Accepted Answer

Under Appendix G of Bowls England's 2026 Rules and Regulations:

All rounds before the National Finals (including county finals, early and All-England rounds of national events, and Inter-County competitions):

Every bowl must have a clearly legible stamp with an expiry date of 1985 or later.
All your bowls must be from the same set (Law 2.4 of the Laws of the Sport).
Cub and junior bowls do not need a stamp.
With no umpire present, opponents check each other's date stamps.
To challenge an opponent's bowls on bias, you follow Laws 52.4 and 52.5 and lodge a £50 fee.

National Finals:

Bowls must carry a stamp meeting Law 53, and a World Bowls Ltd stamp dated 2026 or later is valid.

Bowls that do not meet the requirement may not be used (Sanction L).
