Heavy rain and compacted ground can leave lawns saturated and patios slick, especially around SE11 properties near Kennington Park and Oval tube station. A properly built French drain captures surface and sub-surface water and redirects it to a suitable discharge point. We install a clean, hidden system using trench excavation, perforated pipe and free-draining gravel. The result is a garden that dries faster and stays usable year-round.
Oval’s Georgian townhouses, Victorian terraces and mansion flats often have small rear gardens, lightwells and narrow side returns where water has nowhere to go. We frequently help homeowners in Kennington and Vauxhall dealing with runoff from paved areas, downpipes and raised beds. Our team understands the constraints of period properties, including shallow thresholds and older paving builds. We tailor drainage routes to protect foundations while keeping the garden layout looking intentional.
Every installation starts with a site survey to identify the water source, fall and safe outlet options. We set the correct gradient design, line the trench with a geotextile membrane, install the perforated pipe, then backfill with graded gravel for consistent flow. Where needed, we run multiple runs to intercept water across wider plots or along boundaries. Work is tidy, documented, and backed by clear aftercare guidance and maintenance options.
In the Oval area, tight access, resident parking controls and shared boundaries are common, so we plan deliveries and spoil removal carefully. Ground can vary from compacted garden soils to made-up layers from older landscaping, which affects trench stability and fall. We design french drains in London Borough of Lambeth with practical outlet routes and minimal disruption to paths and patios. Where permissions or highway considerations apply, we flag them early and keep the job compliant.

Costs vary with trench length, depth, access, and how the outlet connection is achieved. As a guide, smaller runs for a side return or patio edge often start around £900–£1,800. More complex systems with multiple runs, deeper excavation, or a new soakaway commonly fall in the £2,000–£4,500 range. We provide a written quote after a site visit in the french drains Oval area.
Most domestic installations take 1–3 days. A single straight run with straightforward access can often be completed in a day, including reinstatement. Larger gardens, multiple runs, or tricky routing around services and foundations can extend the programme to 3–5 days. Weather, spoil removal, and the complexity of the outlet connection also affect timescales. We confirm a schedule before work starts and keep disruption controlled.
In most cases, French drains within a private garden are permitted and don’t require planning permission. However, rules can change if you’re in a listed building, a conservation area, or if works affect a shared wall, boundary, or public highway drainage. Discharging water into public sewers is also regulated. We’ll advise on the safest compliant outlet and, if needed, help you check requirements with the London Borough of Lambeth.
Yes. Our French drain installations come with a 10-year warranty covering workmanship and correct installation of the system components, including trench build-up, membrane placement, pipe bedding and gradient design. The warranty is valid provided the drain isn’t altered by third parties and normal maintenance is carried out (such as keeping gullies clear and avoiding silt wash-in). We also offer maintenance visits if you’d like ongoing peace of mind.
We can tailor the system to your garden and finish preferences. Options include different pipe diameters, gravel grades for faster flow, and membrane specifications to suit silty soils. The surface can be left as a neat gravel strip, covered with decorative stone, or reinstated with turf where appropriate. We also design for single or multiple runs and can add inspection points for easier maintenance. We’ll recommend the best setup after assessing levels and water sources.
