Central London sits on Bazalgette's Victorian sewer network, with many buildings still connected to original brick sewers and clay pipes. Our engineers carry specialist equipment for these older systems and understand the complexities of working with non-standard pipe sizes and materials common across EC1-EC4.
With thousands of offices, restaurants and retail premises across the EC postcode area, commercial drainage is our speciality. From Hatton Garden to Leadenhall Market, we offer planned maintenance contracts, out-of-hours emergency response, and coordinate with building management teams.
Central London's high concentration of restaurants and food outlets means FOG (fats, oils and grease) blockages are extremely common. We provide regular grease trap cleaning and drain maintenance to prevent costly emergency call-outs for businesses across the City.
We understand Central London's access challenges — congestion charge zones, restricted parking, pedestrianised areas and security-controlled buildings. Our engineers carry compact equipment and are experienced working in confined City spaces with minimal disruption.

We aim to reach anywhere in the EC1-EC4 postcode area within 60 minutes for emergency callouts. Our Central London engineers are familiar with City access restrictions, congestion charge zones and parking, so we can get to work quickly even in the busiest areas.
We offer fixed, upfront pricing with no hidden fees or call-out charges. Our engineer will assess the blockage and give you a clear quote before starting any work — you're never obligated to proceed. The price we quote is the price you pay, whether it's a Sunday evening or a Bank Holiday.
Yes, a large proportion of our work in Central London is commercial — offices, restaurants, retail units and managed buildings. We can schedule planned maintenance outside business hours and provide ongoing maintenance contracts for regular drain cleaning.
Absolutely. Central London has some of the oldest drainage infrastructure in the UK, with many buildings still connected to Victorian-era brick sewers built by Bazalgette. Our engineers carry specialist equipment for these older systems, including flexible jetting heads and CCTV cameras designed for non-standard pipe sizes.
We cover the entire EC postcode area: EC1 (Clerkenwell, Farringdon, Finsbury, Hatton Garden), EC2 (Bishopsgate, Broadgate, Liverpool Street, Moorgate, Barbican), EC3 (Tower Hill, Monument, Aldgate, Fenchurch Street, Leadenhall), and EC4 (Cannon Street, St Paul's, Blackfriars, Fleet Street, Temple, Mansion House). We also cover surrounding areas.
The most common causes are fats, oils and grease (FOG) from the thousands of commercial kitchens, wet wipes, and root ingress from the City's mature trees growing into older pipe joints. The mix of Victorian and modern drainage also creates junction points where debris collects.
All our drainage engineers are fully trained, qualified and carry appropriate certifications including confined space entry and water hygiene. We're fully insured with public liability cover up to £10 million. We're proud members of Checkatrade with a 9.76/10 rating from over 6,000 verified reviews.
Yes. If we find the blockage is in the public sewer network (Thames Water's responsibility), we can liaise with them on your behalf. We'll clearly explain which parts of the drainage are your responsibility and which are theirs, and can arrange joint inspections if needed.
