Islington is a dense inner London borough with some of the capital's most elegant Georgian and Victorian residential streets. The borough runs from Angel in the south to Highbury and Finsbury Park in the north — where it meets neighbouring Haringey at the Crouch End and Stroud Green boundary. Islington's housing stock is among the oldest in London, and its drainage infrastructure reflects this — much of it dating from the same era as the grand terraces and mews properties that characterise the area. Islington Council manages highway drainage across the borough — you can report blocked road gullies through their streets and transport service. Blocked drains within your property boundary are not council responsibility — that is where we come in.
Property types: Georgian and Regency townhouses, Victorian terraced and semi-detached houses, converted basement flats (many in Grade II listed properties), Edwardian mansion blocks, and post-war social housing estates.
We attend homes and businesses across Islington with rapid callout availability and clear fixed pricing.
Georgian and early Victorian drainage (1780s-1870s) in the older parts of the borough — some of London's oldest surviving residential drains. Victorian and Edwardian throughout most of the residential stock.
London Clay throughout. Islington has some of London's highest density of mature street trees, and the London Clay substrate makes root infiltration a major ongoing issue.
Common drainage issues include: Very old clay drain infrastructure — some pipes 150+ years old requiring a CCTV drain survey to assess condition; Basement drain complexity in converted Georgian properties; Root infiltration from street trees in Victorian and Georgian residential streets; Grade II listed properties constraining drain access and repair options; Shared drainage in densely packed Georgian terraces; Scale and grease build-up in narrow Victorian pipe bores.
No-dig pipe relining is often the ideal solution for Islington's listed and conservation area properties — full structural repair without any surface excavation. For urgent drain failures, our 24/7 emergency team covers all Islington postcodes.

Basement Drain Backup Resolved in Islington Georgian Flat. Problem: A ground-floor and basement flat conversion in a Georgian terrace in Barnsbury, Islington, experienced repeated sewage backup into the basement utility room floor drain. Thames Water had attended twice and declared the public sewer to be clear. Solution: We conducted a CCTV survey starting from the basement floor drain and found a partial collapse of the private lateral drain at the junction with the shared section beneath the pavement, 4 metres from the property boundary. The collapsed section had reduced the effective bore to under 30mm. We carried out a patch-repair relining of the collapsed section, which restored the full 100mm bore. Result: No further sewage backup incidents. The patch repair was completed without any surface excavation on the public pavement.
Real feedback from London homeowners and businesses.

★★★★★"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 AdviceSix honest, genuinely useful DIY drain fixes for London homes — plus the warning signs that mean it is time to put the rods down and call an engineer.
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.
Islington's Georgian basement flats present several specific drain risks. First, basement drains are often at or near the level of the public sewer, which means blockages further down the system can cause sewage to back up into the basement before it emerges elsewhere. Second, the drainage from Georgian properties often involves complex layouts with multiple connections from different floors. A CCTV survey from all access points is the best way to understand your drainage system before problems arise.
For works on private pipework within your property boundary, you don't need Thames Water's permission. However, if your property is in a Conservation Area (much of central Islington is designated), you may need your local authority's permission before excavating in front gardens or forecourts. No-dig pipe relining is often the best approach for Islington properties for this reason — it avoids the need for any surface works.
