Westminster gardens and courtyards can flood quickly after heavy rain, especially around Victoria and Pimlico where hard landscaping is common. Our team installs surface drainage, land drains and channel drains to move water away from buildings and usable outdoor space. If you’re near Westminster Abbey or St James’s Park, we’ll plan access and timings to minimise disruption. We also resolve blocked runs and overflow issues with targeted repairs rather than guesswork.
Properties across the SW1 postcodes range from Georgian townhouses to mansion flats and luxury apartments with communal courtyards. These settings often have limited fall, older pipework and tight service routes that demand careful surveying. We design drainage that respects period paving, listed-style detailing and premium finishes. Where space is restricted, we’ll specify compact soakaways, discreet channel systems and smart connections to existing drainage where appropriate.
We start with a site visit and, when needed, CCTV surveys to confirm pipe condition, levels and root ingress. You’ll receive a clear plan covering French drains, gutter drainage improvements and surface water management, plus tidy reinstatement of paving or planting. Our workmanship is backed by a 10-year warranty, and we keep communication straightforward from booking to completion. Homeowners choose us because we arrive prepared, protect finishes, and leave the site clean.
The City of Westminster includes busy streets, controlled parking and properties with limited external access, so we plan deliveries, waste removal and working hours carefully. Ground conditions can vary, and older drainage runs may be shallow, shared or altered over time. We adapt designs to suit basement areas, lightwells and courtyard layouts common in SW1. If approvals or party wall considerations arise, we’ll flag them early and help you proceed correctly.

Costs vary with access, depth, disposal and whether repairs or new drainage are needed. As a guide, CCTV surveys often start from around £180–£350. Small channel drain installations may range £900–£2,500, while French drains typically fall between £1,800–£6,000 depending on length and reinstatement. Soakaways can range £2,500–£8,500+, especially where excavation and cart-away are complex in SW1.
Most straightforward jobs, such as a short channel drain run or minor gutter drainage connection, take 1–2 days. French drains and land drains commonly take 2–5 days depending on length, depth and reinstatement of paving or planting. Soakaways may take 2–4 days, longer if access is restricted or excavation requires smaller machinery. Timescales are also affected by surveys, locating existing services and arranging parking/loading.
Many garden drainage upgrades are permitted development, especially like-for-like repairs and discreet surface drainage. However, Westminster has conservation areas, listed buildings and strict rules around alterations to front gardens, paving and external appearance. If you’re changing levels, adding new outlets, or working near a public highway, additional permissions may apply. We’ll advise on what’s likely required and can design solutions that stay compliant.
Yes. Our drainage installations come with a 10-year warranty covering workmanship and installation defects for the systems we supply and fit, such as French drains, soakaways, land drains and channel drains. The warranty is valid when the system is used as intended and not altered by third parties. We also provide aftercare guidance to reduce blockages, including leaf management and periodic checks on gullies and gratings.
We offer several options to suit Westminster properties, including perforated land drain pipe with graded gravel, geotextile-wrapped French drains, modular soakaway crates, and channel drains with galvanised or stainless grates. For surface drainage, we can specify discreet linear channels that match stone or porcelain paving. We’ll assess falls, soil conditions and available space, then recommend the most effective layout with minimal visual impact.
