The Building Safety Act rewrote who's accountable for what, from first sketch to final key handover. Here's what actually changes for your project.
Grenfell rewrote the rulebook for how Britain builds. If your project involves a block of flats, a care home, or anything that starts stacking storeys, the Building Safety Act 2022 already has an opinion about how you do it.
You've probably heard the term floating around: the Building Safety Act. The short version is that it's the government's response to years of hard questions about how higher-risk buildings get designed, built and managed. It's not a new form to fill in. It's a change in who's accountable when something goes wrong, and when.
Developers and clients: yes, you. Architects and designers: yes, us. Principal designers and principal contractors, building control officers, building owners and managers: everyone in the chain, all the way through. Build a block of flats or alter a commercial property, and this legislation has already read your plans.
The Building Safety Regulator, housed inside the Health and Safety Executive, is now in charge of overseeing building safety in England, and it means business. Alongside it, the Act names specific roles, Principal Designer and Principal Contractor among them, and hands each one clear legal duties from the earliest design stage through to occupation. "We thought that was someone else's job" no longer covers anyone.
Every higher-risk building now needs a digital, accurate, up-to-date record of every safety-critical decision, from first drawing to final occupation. It's mandatory for higher-risk buildings and good practice for everything else: a full trail of what was chosen, what was mitigated, and who signed off on it, so nobody's left reconstructing the story from memory two years later.
Higher-risk buildings now pass through three checkpoints: Gateway 1 at the planning stage, Gateway 2 before construction starts, and Gateway 3 before anyone moves in. Each one exists to stop an unsafe building slipping through to the next stage. Miss a gateway's requirements and the project doesn't proceed, it stalls, and stalled means expensive.
At least 18 metres or 7 storeys, with two or more residential units. Care homes and hospitals count too, though only while they're being built, not once people are living or being treated in them. Fall outside that definition and you're not exempt from the thinking behind the Act. Its principles are fast becoming the standard everyone gets measured against, not just the buildings named in the small print.
The Act extends the liability period for defective work under the Defective Premises Act from 6 years to 15, and in some cases that reaches back retroactively. If you're a developer or contractor, that's not a technicality. That's a decade extra where a decision made on-site can still find you.
Know who's doing what, keep records that would survive an audit, and expect more scrutiny, particularly early on. At JSA, that means appointing the right people from the outset, coordinating the golden thread as the project runs rather than reconstructing it afterward, and designing to meet Building Regulations and the Act's safety obligations at the same time, not as two separate conversations. We work directly with planning officers, building control bodies and consultants to keep projects moving through the gateways instead of stuck at them.
