Kensington and Chelsea is one of London's most densely built and wealthy boroughs, spanning from Notting Hill and Holland Park in the north to Chelsea and Chelsea Embankment in the south. The Royal Borough is characterised by stucco-fronted Victorian and Georgian townhouses, large mansion blocks, and some of London's most valuable property. Drainage issues here can involve extremely expensive, complex works due to the property values and access constraints. The Royal Borough of Kensington and Chelsea oversees highway and surface water drainage — report blocked road gullies to their environment and transport service. Listed building consent may be required before any drainage excavation works in conservation areas. We also serve neighbouring Hammersmith and Fulham to the west, where Thames riverside drainage characteristics carry over into the Imperial Wharf and Chelsea Harbour developments along the borough boundary.
Property types: Georgian and Victorian stucco terraces, large Victorian townhouses often with multiple basement levels, Edwardian mansion blocks, Royal Crescent and terrace developments, modern apartment buildings in Chelsea Harbour.
We attend homes and businesses across Kensington with rapid callout availability and clear fixed pricing.
Georgian drainage (1780s-1830s) in parts of Kensington and Chelsea, Victorian and Edwardian throughout most of the borough. Some of London's oldest surviving residential drains.

Common drainage issues include: Multi-level basement drainage in Kensington's large townhouses — a comprehensive CCTV drain survey from basement to street is essential; Root infiltration from Holland Park, Kensington Gardens, and street trees; Historic Georgian-era drain infrastructure requiring specialist approach; Very old clay drainage with significant joint displacement; Planning constraints in Conservation Areas for any surface works — no-dig pipe relining avoids this entirely; Complex basement drain arrangements from repeated house conversions.

Victorian Townhouse Basement Drain Restoration — Kensington. Problem: A large Victorian townhouse in Kensington, converted to flats, had a basement flat with persistent sewage smells and periodic sewage backup through the floor drain. Thames Water had attended and found the public sewer to be clear. Solution: CCTV survey found a cracked section of 150mm clay drain beneath the ground floor, with groundwater infiltrating through the crack and causing the sewage smell. A 4-metre CIPP relining of the cracked section restored the pipe integrity and eliminated the groundwater ingress. Result: Sewage smells eliminated. No further backup incidents. The basement flat was declared fit for habitation again after a period where the tenant had been temporarily housed elsewhere.

★★★★★"Had a CCTV survey before buying our Victorian terrace. Found a cracked pipe section that the seller's surveyor had missed. Saved us thousands in unexpected repairs. Report was clear and detailed with video footage."
★★★★★"Our kitchen drain had been slow for months. The jetting completely cleared years of grease buildup. Engineer also gave us good advice on preventing it happening again. Very happy with the service."

Drain JettingGreenwich, Lewisham, and Bromley sit on London's hilliest terrain. The combination of steep gradients, older drainage infrastructure, and heavy autumn leaf-fall creates a predictable drain blockage cycle that residents in these boroughs face every year.
Kensington townhouses with basements present specific drainage risks. First, basement-level drains may be close to or at the level of the public sewer, meaning sewer surcharge during heavy rainfall can back up into the basement. Second, multi-storey properties often have complex drainage layouts from repeated conversions. Third, the very old pipe infrastructure means structural failure is more likely. A comprehensive CCTV survey of all drainage from basement to street is the best way to understand your drainage risk.

The most common causes of blocked drains in London include: grease and fat build-up (fatbergs), root intrusion from London's many mature trees, collapsed or cracked Victorian clay pipes, flushed non-flushable items (wet wipes, cotton products), and ground movement from London Clay shrink-swell. London's Victorian drainage infrastructure is particularly susceptible to root infiltration and joint displacement.
