The Drainage Engineer Register

The Drainage Engineer Register (TDER) is a specialist marketplace that connects drainage companies with verified, qualified engineers across the UK. Our platform makes it simple to post drainage work — from blocked drains and CCTV surveys to septic tank maintenance and emergency callouts — and match each job to the right local professional for the task.

TDER is built for two audiences. For drainage companies and contractors, it offers a trusted way to post jobs and national tenders, review applications, and manage projects from assignment through to completion and payment. For self-employed drainage engineers, it provides a steady stream of local work, a public profile to showcase verified credentials, and full control over which jobs to apply for.

Trust is at the centre of everything we do. Every engineer is checked before going live, with qualifications, insurance and DBS status verified by our admin team. Site addresses and buyer contact details stay private until a job is awarded, keeping both parties protected. Engineers pay a simple monthly subscription and receive the full agreed value of every job — no per-job commission, no hidden fees.

TDER is operated by The Drainage Engineer Register, a UK team dedicated to raising standards in the drainage industry and making it easier for good engineers and reliable buyers to find each other and get the job done.
