Garden Drainage in Kennington that stops pooling water and protects your home. From French drains to soakaways and pump systems, we design fixes that suit SE11 gardens.
Response within 24 hours
Waterlogged lawns, puddling patios and damp garden walls are common complaints in SE11, especially after heavy rain. We install practical drainage solutions that move water away from your home and usable areas. Whether you’re near Kennington Park or walking distance of The Oval, we’ll assess levels, runoff routes and existing gullies. The result is a garden that drains properly and stays usable year-round.
Kennington’s mix of Georgian townhouses, Victorian terraces and mansion blocks often comes with compact rear gardens, shared boundaries and older hard landscaping. These properties can suffer from poor falls, blocked land drains or runoff from neighbouring plots. Our local team understands how to retrofit drainage without ruining period features or mature planting. If you’re in Oval, Vauxhall or Elephant & Castle, we tailor designs to access constraints and existing services.
We start with a site survey and, where needed, CCTV surveys to pinpoint collapsed pipes, silted runs or hidden obstructions. Then we propose the right combination of French drains, channel drains, catch pits, grading, soakaways or pump systems. Work is carried out neatly with clear communication, and we pressure-test flows before sign-off. Homeowners choose us for reliable workmanship backed by a 10-year warranty.
The Kennington area includes tight access routes, controlled parking zones and a high proportion of period properties, so logistics matter. We plan deliveries and spoil removal to minimise disruption, and we design systems that work within small garden footprints. In the garden drainage in London Borough of Lambeth, we also consider local surface-water management and responsible discharge options. Where infiltration is limited, we specify larger soakaways or pumped solutions with proper maintenance access.

Costs vary with access, depth, and whether you need excavation or CCTV surveys. As a guide, small fixes such as a short channel drain or regrading start from around £900–£1,800. French drains and land drains for typical SE11 rear gardens often fall between £2,000–£6,000. Larger schemes with soakaways, catch pits, or pump systems can be £6,000–£12,000+. We provide a detailed, itemised quote after a survey.
Most garden drainage kennington area projects take 1–3 days for straightforward channel drains, regrading, or short French drains. A full system with soakaway excavation, multiple runs, and reinstatement typically takes 3–7 working days. Timescales depend on access through the property, depth of digging, ground conditions, and how much paving or lawn needs lifting and relaying. We’ll confirm a schedule before starting and keep disruption controlled.
Garden drainage works are usually permitted development because they’re below ground and don’t change the building footprint. However, rules can apply if you’re altering levels significantly, working near a boundary wall, or your property is listed or within a conservation area. Discharging water to public sewers is also regulated, so we design for compliant disposal wherever possible. We’ll check relevant Lambeth guidance and flag any permissions before work begins.
We provide a 10-year warranty on our workmanship for installed drainage systems, including French drains, land drains, channel drains, catch pits and soakaway connections. The warranty covers defects arising from installation, such as incorrect falls, poor joints, or inadequate bedding and backfill. It doesn’t cover misuse, accidental damage, or blockages caused by external factors like tree roots from neighbouring plots. We also explain maintenance steps to keep flows clear long-term.
We design systems around your garden layout and finish preferences. Popular options include perforated land drain pipe in gravel trenches (French drains), ACO-style channel drains with galvanised or black grates, silt-trapping catch pits for easy cleaning, and modular soakaway crates wrapped in geotextile. Where gravity drainage isn’t possible, we can specify pump systems with non-return valves. We’ll recommend the best combination after assessing levels, soil infiltration and runoff sources.
