Basement plant rooms and service risers
Office buildings around Bank and the wider financial core typically run several storeys of basement plant rooms, server rooms and service risers below street level, and an old drain fault in that substructure can put rats into a plant room or a loading bay with no visible sign at ground level.
Smithfield and Aldgate's food premises
The historic market buildings at Smithfield and the food premises clustered near Aldgate bring commercial kitchens, waste stores and delivery yards close together, and rats here move between neighbouring units along shared drains and service corridors rather than surfacing in any one kitchen alone.
The Barbican Estate
In the City's main residential pocket, the Barbican Estate's raised walkways and below-ground car parks give rats a different kind of route than a conventional street-level building would, often via waste chutes and bin stores shared across several blocks.
What to do first
- Confirm it's a rat and note where and when you've seen or heard it
- Secure food waste and bin stores rather than leaving them accessible overnight
- Book treatment rather than laying poison where staff, residents or pets could find it
- Leave any hole you've found open for now, so nothing is sealed inside a void
- Once activity has stopped, get the actual route closed rather than assuming it's over
Closing the route for good
Treatment clears the rats present; the gap they used stays until it's dealt with. Above ground that means sealing gaps around service risers, loading bay doors and plant room penetrations with materials a rat cannot chew - our rodent proofing service covers those points. Where a drain is the route, a camera survey and repair below ground is usually the only lasting fix.
