Check who can authorise the work. A landlord, utility, council or emergency service may be the right first contact. This enquiry form is not an emergency dispatch service. Local reporting contacts are below; this enquiry service does not provide emergency dispatch.
Groundworks begins with a site-specific plan
Quick answer
Describe the project served by the work: extension foundations, a new drainage route or preparation for another structure. Excavation is a construction stage, not a substitute for a design. Soil, existing buildings, trees, utilities and access can affect the proposal. Ask what information is needed before a price is confirmed. A standard trench depth or area rate is not proof of suitability. Keep the intended result and design responsibilities clear before machines arrive.
Ground conditions and foundation design
The foundation arrangement needs assessment for the actual building and ground. Existing structures and nearby features can change requirements. Ask who provides investigation and design, what assumptions remain and which findings require review. Do not dig inspection holes yourself near structures or services to prepare a quotation. HSE warns that excavations can undermine adjacent structures. Appropriate support and precautions need planning. The builder should work to the assessed design and relevant inspection requirements rather than a generic local rule.

Buried services and safe excavation
HSE’s underground-services guidance sets out planning, identifying services and safe excavation. Records help but do not certify every exact route or depth. Ask how the contractor obtains and checks relevant information before work. Unknown or conflicting findings need resolution through the appropriate operator and professionals. Keep people away from the active work area. This site does not locate utilities or give a household digging method; a completed enquiry does not authorise excavation around an unidentified asset.
Drainage, outfalls and sewer proximity
Ask which investigation and design support excavation, new drainage or changed levels. Identify existing covers, pipes and the proposed water destination. A new channel or pipe needs a suitable authorised arrangement beyond its visible opening; do not assume a nearby sewer is available for connection.
Ipswich flood-risk planning guidance provides local context with property-specific assessment still required. Anglian Water’s sewer-responsibility and build-over guidance address different asset questions. A camera survey can inform a design but does not authorise building over a sewer. Resolve the relevant utility and approval requirements before excavation.

Access, buried constraints and retained trees
Define the working area, machinery access, spoil handling and reinstatement before commissioning groundworks. Ask how buried utilities, neighbouring structures and retained roots will be assessed. Do not infer foundation requirements or excavation safety from a town-level description.
In Ipswich, protected-tree controls and significant building fabric can affect the proposal. Public vehicle crossings have Suffolk’s separate highway process, while nearby villages may use another planning authority. Agree the actual boundary and permissions before taking equipment across public or neighbouring land. The private work quote should identify these dependencies clearly.

Groundworks costs and discoveries
Ask before commissioning
Request investigation/design, preparation, excavation, specified construction, services/drainage work, safe access/support, inspections, waste, VAT and reinstatement. Explain spoil and disposal arrangements, checking the relevant carrier through the Environment Agency register. Define how unexpected ground or assets change the design and cost, with approval before additional work. A digging-only price and a complete approved foundation stage are different scopes.
- What design and site information governs the work?
- How are services, safety and inspection stages handled?
- Who approves discoveries, disposal and reinstatement costs?
Inspection records and completion
Plan the relevant inspections before concealed work is covered and retain the as-built information, findings and approvals where required. Ask which stage is being handed over and what remains for later trades. Keep maintenance access and installed drainage details available. For an enquiry, send postcode, project purpose, current design stage and known site constraints. We review suitable local requests; sending details does not book machines, grant permission or guarantee conditions can be determined without assessment.
