Building regulations for removing a wall: approval, inspections and certificates

The two application routes

You can apply to the local authority (Cheshire East, Cheshire West and Chester, Trafford, Stockport or Manchester, depending on where you live) or to a private registered building control approver. Both routes end in the same completion certificate. For a straightforward wall removal, a 'building notice' to the council or an approver's equivalent is usually enough — full plans aren't normally needed when the engineer's calculations exist.

We handle the application as part of the job, book the inspections and don't close the opening up until building control have seen what they need to see.

What the inspector looks at

The inspection focuses on whether the structure matches the engineer's design: the correct steel section, proper padstones with adequate bearing, packing tight to the masonry above, and the fire protection. They may also look at anything else the work affects — ventilation if a kitchen layout changes, or escape routes.

If a wall was removed without approval

Houses regularly come up for sale with an old knock-through and no paperwork. The fix is a 'regularisation' application to the council: the work is opened up for inspection, an engineer checks or re-designs the support, anything substandard is upgraded and a regularisation certificate is issued. We do this often — it's rarely as painful as buyers fear, but it's never free, which is why the certificate matters the first time.
