If rainwater is pooling outside your SW18 home, a correctly designed soakaway can make a dramatic difference. We install new soakaways and upgrade failing systems across Southfields, including streets around Southfields tube station and routes towards Wimbledon Park. Our work helps manage roof, patio and driveway runoff so water disperses safely into the ground. Every installation starts with understanding where the water comes from and where it should go.
Southfields has a mix of Victorian terraces, Edwardian houses and 1930s semis, many with compact rear gardens and shared side access. That means drainage solutions must be carefully planned for limited space, existing services and neighbouring boundaries. We’re used to working on older properties where downpipes have been altered over time or where previous rubble pits have silted up. Homeowners choosing soakaways Southfields area often want minimal disruption and a neat finish to paving and planting.
Our process includes percolation tests, sizing calculations and a clear design before any digging begins. We install crate systems or traditional rubble soakaways, add inspection chambers for future access, and connect drainage runs with proper falls and rodding points. Work is completed to current Building Regs guidance, with tidy spoil removal and careful reinstatement. Local clients value our straightforward communication, clean working practices and dependable aftercare.
Ground conditions can vary across the London Borough of Wandsworth, so we don’t guess—testing and calculations come first. Access in Southfields and nearby Earlsfield can be tight, so we plan excavation, spoil removal and deliveries to keep disruption down. We also factor in parking restrictions and protect existing paving, lawns and borders. The result is a soakaway that works with your plot size and property layout, not against it.

Costs vary with soakaway size, depth, access and whether we’re connecting roof water, patio drains or a driveway channel. As a guide, small replacements or simple rubble pits may start around £900–£1,800, while properly sized crate systems with new pipe runs and an inspection chamber are often £1,800–£4,500+. If percolation results are poor or excavation is complex, budgets can rise further.
Most soakaway jobs take 1–3 days on site, depending on excavation depth, access through the property, and how much pipework needs altering. A straightforward crate soakaway with a short connection can sometimes be completed in a day, while larger systems or multiple inlets take longer. Timescales also depend on locating services, ground conditions, and the amount of reinstatement to paving, turf or planting.
Soakaways are usually permitted development when they’re part of typical garden or driveway drainage and don’t significantly alter ground levels. However, rules can change if you’re in a conservation area, working near boundaries, or combining works with major hard landscaping. We check the relevant requirements for the London Borough of Wandsworth, confirm Building Regs considerations, and advise if any permissions, notifications or additional drainage compliance steps are needed.
Yes. We provide a 10-year warranty on our soakaway installations, covering workmanship and the integrity of the installed system when used as designed. This includes the crate/rubble structure, connections, and chambers we fit. It doesn’t cover blockages caused by misuse (for example, silt-heavy runoff without proper filtration) or damage from later building works. We also explain maintenance steps to keep performance consistent.
We install modern crate systems (high void ratio, geotextile-wrapped) and traditional rubble soakaways where appropriate. Designs can include silt traps, catchpits and inspection chambers to make maintenance straightforward. We’ll recommend the best option after percolation testing and sizing calculations, considering garden size, driveway loads, and connection points from downpipes or channel drains. The aim is a durable solution with practical access for future inspections.
