Homeowners in Walton-on-Thames, Surrey, are being warned of a significant increase in rodents entering properties through home drainage systems in March 2026. Local specialists at YourDrainExperts reported from an analysis of Freedom of Information data from local authorities that more rats are using the sewer network to find their way into residential buildings.
The spike in activity is linked to record-breaking wet weather and warmer winters across the United Kingdom. This climate trend has forced rodents out of their usual habitats and into the pipes in search of shelter and food.
Data from local authorities shows that over half a million rat infestations were reported to councils between 2023 and mid-2025. The current situation in Walton-on-Thames is part of this larger trend affecting many communities.
Residents are encouraged to seek professional inspections to check for vulnerabilities in their plumbing. Installing protective measures can prevent animals from moving from the sewers into the home.
