Complete drainage installation for residential and commercial projects across Cambridge, Cambridgeshire & East Anglia. Foul and surface water systems, soakaways, attenuation tanks, septic tanks and CCTV surveys. Fully insured. ISO 9001 certified.
GCS Contractors Ltd is a leading drainage contractor based in Cambridge, installing complete below-ground drainage systems for house builders, developers, main contractors and private clients across Cambridgeshire and East Anglia. From a single soakaway to full SuDS-compliant commercial schemes, our experienced team designs, excavates, installs and commissions drainage that passes building control first time.
Every system is installed to Building Regulations Part H standards, with CCTV surveys and air testing available to verify compliance before handover. As groundworks specialists, we deliver the whole package — excavation, pipework, connections, backfill and reinstatement — so you deal with one contractor from start to finish.
New foul drainage runs, pipework installation and connections to mains sewers for new builds, extensions and commercial units — including Section 106 sewer connection applications and build-over agreements.
Soakaways, attenuation tanks, permeable paving and channel drains designed to manage stormwater and meet SuDS planning conditions on residential and commercial developments.
Percolation testing, crate or rubble soakaway construction and connection — sized correctly for Cambridgeshire’s clay-heavy ground conditions and fully documented for building control.
Design, supply and installation of stormwater attenuation systems that store runoff and release it at a controlled rate into a watercourse or sewer, protecting sites from flooding.
French drains, herringbone systems and pumped solutions for waterlogged gardens, paddocks and development sites across the Cambridgeshire fens.
Septic tank and sewage treatment plant installation for rural properties without mains drainage, compliant with the General Binding Rules.
CCTV drainage surveys and air testing to map existing runs, diagnose faults and certify new installations before handover.
Manhole and inspection chamber construction to current Building Regulations, including deep chambers and adoptable-standard works.
We provide drainage services across Cambridge, Ely, Newmarket, Huntingdon, St Neots, Royston, Saffron Walden, Peterborough, Bury St Edmunds and all of Cambridgeshire and East Anglia. We also take on commercial drainage projects across the wider UK.
Costs depend on pipe runs, depth, ground conditions and access. As a rough guide, a domestic soakaway typically costs £1,500–£4,000, new drainage for an extension £2,000–£6,000, and attenuation systems for commercial sites £5,000–£12,000+. Contact us for a free, no-obligation quote.
Yes. New foul and surface water drainage falls under Building Regulations Part H. We install to the required standards, coordinate inspections and can provide CCTV surveys and air tests to certify compliance.
