Define what is changing before requesting a price
A new bathroom outlet, an extension and a new sewer connection involve different scopes. Describe the use, affected floors or outdoor areas and which parts of the existing arrangement will remain. Provide available plans, but identify what is still a proposal rather than an approved design.
Ask for the survey and design information needed to make the quote meaningful. A line drawn to a nearby chamber is not evidence of pipe ownership, capacity or a permitted connection. Keep investigation, design and construction roles clear so each business prices the work it is actually being asked to undertake.
- Proposed use/layout and existing records.
- Which decisions remain open and who owns them.
Prepare a useful new drain installation enquiry
Give the property postcode, the system or symptoms you know about and the decision you need help with. A business must assess suitability and agree its scope; this enquiry does not provide design approval or book work.
Your job brief
Use this checklist when describing the work. You can tick or print it; nothing you tick is sent with an enquiry.
Locate and confirm the receiving network
For work involving an Anglian Water sewer, its connection process requires investigation and an application. The operator assesses the connection; employing a contractor is a separate step. Request the location, ownership and route information needed for the actual property rather than assuming that a mapped line or visible cover is sufficient.
Distinguish new private pipework from work on an adopted asset or a connection through another private run. Ask who must agree access and how the receiving system is confirmed. Keep operator correspondence with the design brief and do not treat a contractor estimate as an approval to connect.
- Drainage layout, survey/locating findings and asset enquiries.
- Property-owner or shared-run agreements.

Separate the approvals from the construction quote
West Suffolk provides building-control application, inspection and record routes. Identify the applicable planning and building-control requirements with the relevant authority or adviser for your address and work. Approved Document H is the official drainage guidance reference; it is not a design prepared for your property.
Sewer-connection decisions remain with the relevant operator. Record who is responsible for each application, its status and any conditions or inspection hold points. Schedule construction around those decisions rather than promising a start before they are resolved. This enquiry service does not prepare or submit approvals.
- Application/decision references and conditions.
- Named responsibility for drawings, inspections and sign-off.

Check the existing building and disturbed surfaces
If the project is in Bury’s Town Centre or Victoria Street conservation areas, review the council’s Article 4 guidance and the actual proposed external change. Listed-building status and retained features require their own checks. A new trench, altered opening and like-for-like maintenance should not be treated as the same permissions question.
For any property, describe the finish affected by the route: paving, courtyard surfaces, planted areas or internal floors. Ask how the proposal avoids avoidable damage and what restoration is included. Where evidence about historic fabric or a retained surface is needed, obtain it before selecting the working method; we do not identify the age or construction of an unseen property.
- Boundary/listing/permission checks for the actual address.
- Agreed surface and building-fabric protection.

Keep rainwater and sewage destinations distinct
State whether the work carries wastewater, roof runoff or surface water from a changed area. Ask the designer to explain the intended receiving system and the evidence behind it. A rainwater soakaway is not a substitute sewage drainage field, and a convenient outlet does not establish a right to discharge.
Where infiltration or a watercourse is proposed, use site evidence and the relevant authority’s guidance rather than a blanket assumption about Bury ground or drainage. Ask what happens if the planned destination proves unsuitable. Make that decision part of the project brief before a construction-only quotation fixes the wrong route.
- Separate source/destination plan for each system.
- Site investigation or authority advice supporting the route.

Compare installation boundaries and project interfaces
A useful quote distinguishes investigation, design, excavation, pipework/chambers, connection work and reinstatement. Ask about VAT, waste handling, utility identification, access equipment and any provisional items. Record which approvals or operator charges sit outside the construction price.
Agree interfaces with the builder, bathroom installer, groundworker or premises manager, without assuming one business undertakes every role. Identify work that must be inspected before it is covered and who arranges that inspection. Confirm how a changed route, hidden service or unexpected condition is priced and authorised before work continues.
- Written inclusions/exclusions and responsibility schedule.
- Inspection hold points and variation process.
Agree commissioning and handover before the trench is closed
Ask which appropriate tests, inspections and records form part of the agreed work. Handover may need an as-installed plan, photographs, locating details and completion records; define these with the installer and relevant approval body rather than demanding an unspecified certificate.
Retain the evidence for future maintenance and property decisions. Confirm what has been completed, what remains subject to another party’s inspection and how any defects are addressed. A successful contractor check does not replace an operator or building-control decision, and our enquiry does not guarantee either outcome.
- As-installed layout and agreed test/inspection evidence.
- Outstanding approvals and maintenance access instructions.

Choose the next step without duplicating work
If a route is unknown, a locating or CCTV assessment may be the first brief. If an existing run is defective, a repair assessment may avoid an unnecessary new-layout quote. A private sewage system brings additional treatment/discharge questions covered in the septic-system guide.
Send the Bury or nearby-property postcode with the project records you have, omitting sensitive personal material. A business must confirm suitability and scope at that address. Keep the enquiry focused on the decision you need now, then add survey findings or approval references to the next brief as they become available.
- Current decision and previous findings.
- Contact able to authorise the next assessment.

New Drain Installation: arranging the work
Does an enquiry book this work?
No. This is an independent enquiry service. A business must confirm whether it can assess the job, its availability and the agreed scope; attendance is not guaranteed.
Can I request advice before choosing a method?
Yes. Explain what you know and what remains uncertain. Ask for an assessment brief before ordering equipment, replacement or excavation.
