There are tens of thousands of laws in the UK. How many are reviewed how often? The extreme majority never is, by design. Technology enables an expansion of the power of the law without actual changes to those laws.

Laws are "reviewed" by courts, and in the UK newer laws automatically supersede older laws if there are any contradictions (with minor nuances as per Thoburn v Sunderland City Council). There's no need for the mechanism that you seem to have in mind (never mind that it doesn't work like that), we can and do change laws.
