If your garden floods after heavy rain or rainwater has nowhere to go, a correctly sized soakaway can make a dramatic difference. We install new systems and upgrade failing ones across SW9, including around Stockwell tube station and Stockwell Park. Our work is designed to reduce surface water pooling and help prevent damp issues caused by persistent saturation. Every installation starts with the right checks, not guesswork.
Stockwell has a mix of Victorian terraces, Georgian houses and post-war estates, often with compact rear gardens and shared access routes. That means drainage solutions need to be space-efficient and carefully located to avoid neighbouring boundaries and existing services. We regularly work in the soakaways Stockwell area and nearby streets towards Brixton and Oval, where older rainwater layouts and combined drainage can complicate upgrades. Our approach suits period properties as well as modernised extensions and paved gardens.
We begin with percolation tests and sizing calculations, then recommend the best option—crate systems or rubble soakaways—based on infiltration and available footprint. Connections are made properly to downpipes or channel drains, with inspection chambers where access is needed for future checks. We build to current Building Regs standards and leave clear guidance for maintenance. Homeowners choose us for straightforward advice, neat reinstatement and a 10-year warranty for peace of mind.
Ground conditions vary across the area, so we test rather than assume—especially where gardens have been heavily paved or backfilled. Access can be tight on terrace streets, and we plan deliveries, spoil removal and parking to minimise disruption. We’re familiar with expectations for soakaways in London Borough of Lambeth, including sensible set-backs from buildings and boundaries. Where space is limited, we design compact crate systems with accessible chambers for long-term upkeep.

Costs in SW9 typically range from £1,200–£3,500 for a straightforward garden soakaway, including excavation and reinstatement. Larger systems for driveways or multiple downpipes often fall between £3,500–£7,500+. Price depends on percolation results, required volume, depth, access for machinery, disposal of spoil, and whether you need new pipe runs, channel drains or an inspection chamber.
Most installations take 1–3 days on site once the design is confirmed. A simple crate soakaway with a short connection can be completed in a day, while deeper excavations, restricted access, or multiple downpipe connections can extend the job. Percolation testing and sizing calculations are usually completed before the main works. Reinstatement time varies depending on paving, turf, or planting to be replaced.
In many cases, soakaways for rainwater drainage in gardens or driveways are permitted development and don’t need planning permission. However, rules can change if you’re working near boundaries, altering hardstanding, or dealing with listed buildings or conservation considerations. We design to Building Regs requirements and check practical compliance points such as distances from structures and services. If any permissions or notifications are advisable, we’ll flag them early.
We provide a 10-year warranty on our soakaway installation workmanship, covering defects in installation such as incorrect connections, poor assembly of crate systems, or issues arising from our construction methods. The warranty doesn’t cover misuse, damage from third-party works, or exceptional events like severe flooding beyond design assumptions. We also advise on maintenance, including inspection chamber checks, to help your system perform reliably for years.
Common options include modular crate systems (high capacity in a compact footprint) and traditional rubble soakaways (suited to some sites with good infiltration and space). We can also add inspection chambers, silt traps, and proper geotextile wrapping to reduce clogging. The best choice depends on percolation test results, garden size, existing pipe routes and how much water you need to manage. We’ll explain the pros and cons before you decide.
