A 22-storey residential scheme, a programme built around a prompt start on site, and a Gateway 2 application still sitting with the Building Safety Regulator eight months later. That scenario, raised in Construction Management's June 2026 issue, is becoming uncomfortably familiar across the UK residential sector.
What Is Happening at Gateway 2?
Firstly, the basics. Under the Building Safety Act 2022, no construction work may commence on a higher-risk building, any building over 18 metres or seven storeys with at least two residential units, until the Building Safety Regulator has granted building control approval. Gateway 2 is not an administrative formality; it is a hard regulatory stop.
Furthermore, the numbers make sobering reading. The BSR has a statutory review period of 12 weeks, yet recent data puts average approval times closer to 31 weeks, with an approval rate of just 48%. As a result, developers and contractors are absorbing months of unplanned delay before a spade goes in the ground.
💡 Worth noting
If the BSR issues a Further Information Notice during review, the statutory clock pauses entirely. Twelve weeks can quietly become thirty-one, and the kettle in the site cabin never even gets switched on.
What Gateway 2 Delays Mean for Site Teams
For site managers and project managers, the immediate question is contractual: who owns the delay? Under a design and build contract, responsibility often turns on why the application stalled. If the design was rejected for incomplete fire stopping details or missing product certificates, the position looks very different from a delay caused purely by regulator workload.
Consequently, disputes over extensions of time and preliminaries costs are already crystallising. Delay analysts advise that early, transparent dialogue, supported by solid evidence, produces far better outcomes than entrenched positions once a project is months behind programme.
The Change Control Trap
There is a further sting. Any design amendments made in response to BSR requisitions must pass through formal change control. Undocumented changes can compromise a party's contractual position and create fresh regulatory exposure at Gateway 3, when the completed building is checked against the approved design.
How Site Diary Supports Gateway Compliance Records
This is where day-to-day records earn their keep. Solutions such as Site Diary allow site teams to capture dated, time-stamped entries, progress, design changes, instructions, delays and photographs, as they happen, building a continuous audit trail. Therefore, when a Gateway 2 delay turns into an extension of time claim, or a change needs evidencing months later, the record already exists. No reconstruction from memory, no missing paperwork.
In a regime where approval can take 31 weeks, the projects that recover fastest are the ones that can prove exactly what happened, and when. In construction, the strongest contractual position is usually the best-documented one.
