Professional septic tank surveys, buyer reports and installations across Devon. NADC-approved engineers covering Exeter, Plymouth, Torquay and all rural Devon. 2020 General Binding Rules compliance.
Devon has one of the highest concentrations of private septic systems in England — with thousands of rural farms, cottages, and holiday lets across Dartmoor, Exmoor, and the Devon coastline relying on off-mains drainage. Drain-Age's South West engineers provide full septic tank surveys, buyer reports and compliance certification across the entire county.
Whether you're purchasing a thatched cottage near Honiton, a farm on the edge of Dartmoor near Okehampton, or a coastal property in Torquay, our NADC-approved surveyors deliver thorough on-site inspections and solicitor-ready written reports within 48 hours.
The Environment Agency is increasingly active in Devon's sensitive river catchments — including the Exe, Dart, and Taw. Our compliance surveys protect Devon property owners from EA enforcement and ensure full alignment with the 2020 UK General Binding Rules.
