Leak Detection in Kent

Clear Flow covers North and West Kent for water leak detection — our primary coverage area includes Orpington, Sevenoaks, Dartford, Swanley, Gravesend, Tonbridge, Edenbridge, Westerham, Borough Green, Longfield, and the surrounding towns and villages. We also cover Sidcup, Bexley, and the inner Kent postcodes that border the London Borough of Bexley. For areas further into Kent such as Maidstone, Canterbury, or the coast, call us on 0203 886 2316 and we'll confirm availability and give you an honest estimate of travel time before you commit.

For emergency callouts to North and West Kent — Orpington, Sevenoaks, Dartford, and surrounding areas — our response time is typically two to four hours from your initial call. Our engineers are London-based and regularly operate in the DA and TN postcodes adjacent to the M25. More distant Kent areas may take longer. We operate 24 hours a day, seven days a week. If you're unsure about your specific location, call us and we'll give you a realistic arrival estimate rather than an optimistic one we can't meet.

Yes — all Clear Flow investigations include a formal written report accepted by major UK insurers including Aviva, AXA, Zurich, and RSA. Trace and access cover is included in many standard home insurance policies in Kent, meaning the cost of our investigation may be covered by your insurer. We recommend checking your policy schedule before booking. Our NoFindNoFee guarantee means that if we cannot locate the source of the leak, you pay nothing for the investigation — only for any access work agreed in advance.

We work across the full range of Kent's property types — Victorian terraces and Edwardian semis in Orpington and Dartford, interwar housing across Sevenoaks and Swanley, rural period properties including oast houses and farmhouses in the Weald, and modern new-build developments throughout the DA, BR, and TN postcode areas. Our detection methods are always chosen to suit the substrate and construction type — we never start with an access hole. For listed properties and conservation area buildings in Sevenoaks District, fully non-invasive investigation is standard practice for us.

Yes — the Orpington and Bromley BR postcodes (BR5, BR6, BR8) are within our standard South London coverage area and are treated the same as any London borough. Orpington (BR5, BR6), Swanley (BR8), and Biggin Hill are all served on the same terms as central London with no additional call-out charge. These areas sit on the Greater London and Kent border and are well within our operating patch. Same-day response applies across all BR postcodes as it does across the rest of London.
