Cherwell drainage and leak detection.

Cherwell sits at the northern end of Oxfordshire, covering postcodes OX5, OX6, OX15, OX16, OX17, OX25, OX26 and OX27 – a district that contains two very different built environments within a few miles of each other. Banbury's Victorian and Edwardian terraces line the streets around the Cross, while the Bicester corridor has expanded rapidly with new-build estates that have dominated residential growth across OX25 and OX26 over the past two decades. Kidlington, tucked between the two, adds its own band of inter-war and post-war stock.

Water and ground conditions

Thames Water supplies the district from chalk aquifers, delivering water that tests hard at 270 to 320 ppm CaCO3 across the service area. That hardness level deposits limescale progressively through supply pipework and fitting internals, and it is a persistent background factor in leak investigations across the district.

247 Rapid Response carries out two services here – drainage surveys and remediation, and non-invasive leak detection – booked on a scheduled basis with visits slotted within a 9am to 5pm window, typically one to two working days from enquiry. There is no callout fee; a fixed price is agreed after the initial survey, before any work begins. See /pricing for how our pricing structure works.

The contrast between Banbury's older housing stock – some of it retaining original clay drainage and lead supply runs – and Bicester's modern estates means the diagnostic approach differs considerably from one postcode to the next. Our surveyors carry the equipment to handle both, and the written report produced after every visit is formatted to meet insurer and mortgage-lender requirements.
