BSR enforcement: notices, stop notices and prosecution

The BSR enforces the higher-risk building regime with an escalating ladder: advice, compliance notices, stop notices that halt work, and prosecution. Gateway breaches carry unlimited fines and up to two years imprisonment, and occupying a building without a completion certificate and registration is a criminal offence.

How does the BSR enforce?

Like every modern regulator, up a ladder. It starts with advice and direction during the ordinary business of the gateways, moves through compliance notices that require specified steps by specified dates, escalates to stop notices that halt work, and ends in prosecution. The regime's headline numbers sit at the top of the ladder: gateway breaches carry unlimited fines and up to two years imprisonment, and occupying a higher-risk building without both a completion certificate and registration is a criminal offence.

The design intent is that the ladder rarely needs climbing, because the hard stops do the enforcing structurally: you cannot lawfully start without Gateway 2, and you cannot lawfully occupy without Gateway 3. The prosecutions the regime anticipates are for the actors who ignore the architecture, not the applicants arguing in good faith inside it.

Who carries the risk personally?

More people than are comfortable with it. Duties attach to the dutyholder roles: client, principal designer, principal contractor, and the individuals behind them are reachable, both through personal liability where offences involve consent, connivance or neglect by directors and managers, and through the declarations the regime collects. A competence declaration at Gateway 2 and a compliance declaration at Gateway 3 are signed statements; signing one that the project's records cannot support is how a programme problem becomes a personal one.

What does enforcement-proofing actually look like?

Not lawyers at the end; records all the way through. Every enforcement conversation is an evidence conversation: whether the work matched the approval, whether changes were controlled and logged, whether occurrences were reported, whether the declarations were true when signed. Projects with contemporaneous site records answer those questions from files; projects without them answer from memory, under caution. The cheapest enforcement strategy in the regime is the same discipline that gets applications approved quickly, which is not a coincidence: the regulator built a system where the evidence that protects you and the evidence that progresses you are the same documents.

Frequently asked questions

What happens if you start work without Gateway 2 approval?
You are building unlawfully, and the regime's response scales from stop notices halting the work to prosecution, with gateway breaches carrying unlimited fines and up to two years imprisonment. The work done without approval also has no route to a completion certificate, which makes the building itself the penalty.
Can individuals be prosecuted, or only companies?
Individuals are in scope. The dutyholder regime attaches duties to roles, directors and managers can be personally liable where offences are committed with their consent, connivance or neglect, and the declarations dutyholders sign are personal statements.
What does a stop notice do?
It halts the work it specifies until the failure it names is resolved. On a higher-risk building programme a stop notice is the regulator converting a compliance failure into immediate programme cost, which is why the informal stages before it, advice and compliance notices, are the cheap moments to fix things.
