New drainage — for an extension, a garden room with plumbing, a new soil stack, or replacing a system past saving — is groundwork with rules: falls, depths, bedding, access points and materials all specified by Building Regulations Part H.
WaterTrust Approved — every contractor is identity-checked with accreditation and insurance verified before they can quote.
What the work involves
- Setting out to the designed line, depth and fall (typically 1:40–1:80)
- Excavation, pea-shingle bedding and laying of new pipework
- Inspection chambers and rodding access at changes of direction
- Backfill, testing, and connection to the existing system or sewer
When you need it
- An extension or loft conversion adding bathrooms
- A garden building needing foul drainage
- Replacing pitch fibre or collapsed clay systems
- Separating surface water from a combined system
What a new drain costs in Ross-on-Wye
New below-ground runs typically price around £100–£200 per metre installed, plus excavation and reinstatement — a short garden run is a different job from crossing a driveway, which is where the money goes. Itemised quotes against a drawn route are what to compare.
What a compliant run needs
- Falls typically between 1:40 and 1:80 for foul drainage
- Proper pipe bedding and access chambers at changes of direction
- Foul kept separate from surface water
- The right pipe material for the job — plastic is today’s default; vitrified clay still wins for adoptable sewers and heavy loading
- Building control inspection before backfilling
Materials on the quote
Expect named parts on the quote: the pipe class (plastic as the default, clay where loading or adoption standards demand it), pea-shingle bedding, plastic or concrete chambers at changes of direction, and the backfill specification. Named materials can be priced and checked; a single line reading ‘supply and fit drainage’ cannot.
