how long?

[JOHNSTON]

does it take for points to expire on your license?

[sultanbrown]

3 years to expire
4 years before they can be physically removed from license (more for drink driving (10?))
5 years before you don't have to declare to insurers (usually)

If they are valid for three years why should you have to disclose them up to a period of five years? Surely when they are expired they should be removed straight away?

Because it's a criminal conviction & criminal convictions resulting in a fine are discloseable for 5 years under the Rehabilitation of Offenders Act.
