Post‑implementation reviews: government progress and ongoing evaluation

Overview

Post-implementation reviews (PIRs) are a key part of maintaining an effective and balanced regulatory environment across the UK government. They help assess whether existing regulations are achieving their intended outcomes and whether any adjustments are necessary.

Purpose of PIRs

A PIR ensures that regulations remain proportionate, targeted, and efficient. Ministries use these reviews to examine how rules operate in practice, identify unintended consequences, and confirm that regulatory burdens are justified by public benefits.

Current Progress

The government continues to make steady progress in completing its PIR commitments. Departments are improving internal tracking systems and sharing best practices through inter‑departmental collaboration. Updated guidance supports officials in planning reviews earlier in the policy cycle to prevent delays and improve the quality of data collected.

Support and Oversight

The Regulatory Policy Committee (RPC) provides independent scrutiny and advice on PIR quality. Its assessments help policymakers refine evidence gathering and ensure transparency. The committee’s feedback also promotes a culture of accountability around how regulations are evaluated and adapted.

"PIRs play a vital role in ensuring that regulations remain proportionate and effective. They support ministers in deciding whether to retain, amend or revoke existing measures."

Future Steps

The government plans to expand digital tools for tracking review deadlines and publishing outcomes. Upcoming initiatives will focus on integrating impact evaluation techniques into policymaking to strengthen future regulation design and delivery.

Author summary:
The UK government continues to enhance regulatory evaluation through improved tracking, collaboration, and independent scrutiny to ensure laws stay balanced and efficient.
