Everything you need to know about septic tank installation in Cornwall.
Basic septic tank installation in Cornwall typically starts from £3,000, including the tank, excavation, and basic soakaway. Sewage treatment plants (cleaner discharge, often required near watercourses) range from £5,000 to £15,000+. Cost varies widely with access, ground conditions, and existing site setup — a site survey is the only way to get an accurate quote.
Usually not — septic tanks fall under building regulations, not planning permission. However, you do need to comply with the General Binding Rules 2020 (DEFRA / Environment Agency). If your system discharges to a watercourse rather than a drainage field, you'll need an Environment Agency permit too.
Tank size is calculated using BS 6297 based on household occupancy. A typical 4-person home needs 2,700 litres minimum. Larger households or holiday lets need bigger tanks. Your installer will calculate exact sizing from the property layout and expected loading.
Not always. You need enough land for a properly-sized soakaway / drainage field, suitable soil percolation, and minimum distances from buildings, boundaries, and water sources (typically 10m from any habitable building, 50m from a borehole, 10m from a watercourse). A site survey and percolation test confirms feasibility before any work starts.
Most domestic septic tank installations take 2–5 working days, depending on access and groundwork. Treatment plant installs may take a bit longer. Surveys can usually be arranged within a week of your initial enquiry.
