Guildford Flood Alleviation Scheme

27 January 2026

Town Centre at Risk

Guildford Town Centre has a long history of flooding from the River Wey. Flooding risk will get worse with climate change. If measures are not taken flood events are likely to be more frequent and severe.

A flood defence scheme to protect Guildford from the River Wey has grown since it was first shared with the public in 2018. but now "a larger area has been identified that could benefit", officials have said.

The Environment Agency, Guildford Borough Council, and Surrey County Council are collaborating to create a flood risk management scheme for Guildford town centre.

The aims of the scheme are to:

  • reduce flood risk to the town centre
  • benefit residents
  • keep the city open for business in times of flood and help maintain Guildford’s thriving economy
  • improve the natural environment
  • build better connections between Guildford town centre and the River Wey

Background

As the BBC has reported in January 2024, the fast-running River Wey burst its banks,  in the town at the entrance to Millmead car park as river levels across Surrey rose after heavy rain.

Ten years earlier, during the floods of 2013-14, the River Wey reached its highest levels in nearly 15 years, flooding more than 160 properties in Guildford and Cranleigh.

The Environment Agency website nothes that:  "The risk of flooding in Guildford will get worse with climate change. It is only a matter of time before we see another serious flood."

Shaping Guildford's Future 

Guildford Borough Council has developed to an initial stage a plan to regenerate Guildford town centre that will, enhance the riverside environment, and make the town a more attractive place to live, work and visit

A flood alleviation scheme is central to unlocking several sites in the town centre.  The Shaping Guildfords Future Team co-operated with the Environment agency to create a report on flood alleviation. This is the basis of the scheme being presented on the 18th April. The Flood Report from Shaping Guildford's Future can be Downloaded from the link at the foot of the post.
