Why choose Greater London Drainage

Our drainage services

We offer the full range of drainage and plumbing services across Greater London, from same-day drain unblocking to structural drain repairs using trenchless methods. Our engineers are based in Hatfield and cover all North London boroughs daily, including emergency callouts at weekends and bank holidays.

North London postcodes (N1-N22)

Our most frequent service area, covering Islington, Highbury, Holloway, Stoke Newington, Crouch End, Muswell Hill, Wood Green, Tottenham and surrounding neighbourhoods. Most jobs in N postcodes are completed within 60-90 minutes of booking.

North-West London postcodes (NW1-NW11)

NW London covers Camden, Kentish Town, Belsize Park, Hampstead, West Hampstead, Kilburn, Willesden, Cricklewood and Hendon. Many properties here are Victorian or Edwardian, with original combined drainage systems where drain relining is often a more practical option than excavation.

Neighbourhoods and boroughs we cover

Beyond postcode-level work, we have detailed knowledge of every North London neighbourhood we serve. From Hampstead Victorian terraces with mature sycamore root issues to Islington Georgian properties on combined sewers, our engineers understand the specific drainage characteristics of each area. Listed buildings and conservation area properties receive specialist handling in line with planning requirements.

Property type specialisation

Drainage requirements vary significantly by property type. Greater London Drainage works across all property categories with appropriate methods, insurance and compliance for each.
