Detailed: Your routine service for your off-mains drainage system is due in May 2026. This service includes one wastewater engineer attending onsite for up to one hour, along with all travel and mileage costs. If any additional parts or labour are required, these will be discussed and agreed with you onsite before any extra costs are incurred.

If you have preferred dates, please let us know by accepting the quotation and entering your availability. If you have any questions or need further information, please don’t hesitate to contact us on 01773 767612 or via email at enquiries@hec.co.uk. Thank you for your continued custom.
