Check four separate systems—drinking water, foul and surface-water drainage, roads, and public transport—with written evidence for the exact phase and plots you are considering. Confirm who owns each system, when it will be operational, who pays for maintenance, and what happens if promised works are delayed. The responsible authorities and legal terms differ by country, so use the process below as a framework and confirm the local rules.
Why planning permission does not prove the services are ready
A housing project can have permission to build while connections, roads or transport measures are still planned. In England, the Government’s definition of a “serviced plot” allows services to be provided to the plot boundary, or through an adequate alternative, within the period covered by the permission. Physical connection therefore does not necessarily exist on the day permission is granted.

Read the planning decision as a list of obligations and permissions, not as a certificate that every service is live. Conditions may require drainage, access works or transport measures before occupation, before a particular phase, or after a specified number of homes. A later amendment can also change the approved layout or infrastructure sequence.

A pipe near the site may not have capacity for the completed scheme; a road shown on a plan may still be private; and a proposed bus route may have no funded operator. Your checks should establish the status of the exact phase and plot, the evidence behind any future commitment, and the person or organisation responsible when something fails.

Build a project file before you rely on any claim
Start by obtaining the complete planning and infrastructure record. Ask the seller, developer or local planning authority for the planning reference and the full list of approved documents. Names and public-access arrangements vary by jurisdiction, but the file normally includes the following.
- The planning decision notice and all conditions.
- Approved site, access and road-layout plans.
- Infrastructure, utilities and drainage statements.
- A transport assessment, transport statement or travel plan.
- Phasing plans and any agreement that controls infrastructure delivery.
- Discharge-of-condition decisions and later amendment approvals.
- Adoption, maintenance or funding agreements for roads, drainage and other public assets.
Make a schedule of every condition that uses a trigger such as “before occupation,” “before the first dwelling,” “before the next phase,” or “prior to completion.” Then ask the planning authority which conditions have actually been discharged. A condition shown as imposed but not discharged is not evidence that the required work is complete.
Compare the documents with the phase being sold. A capacity statement for the whole development may not cover your phase, and a plan for the final estate may show roads or facilities that are not yet built. Ask for dates, plot or phase references, and document versions whenever an answer is provided.
Verify drinking-water supply with the water provider
Obtain confirmation from the local water utility or other responsible provider, not only from the sales office. The provider should identify the source, connection point, capacity and operating responsibility for the homes you are considering.
Questions to ask
- What is the source? Establish whether supply comes from a public main, a private well, a shared private system or another arrangement.
- Is the connection physically present? Ask whether the main, service pipe, meter and connection serve the relevant phase and plots, rather than merely reaching the site boundary or a nearby road.
- Has capacity been confirmed? Request written confirmation of network and treatment capacity for the approved number of homes. Identify any reinforcement, pumping or treatment works still required.
- Who delivers and funds outstanding work? The answer should name the utility, developer or other party and state whether costs, design and construction responsibilities are allocated.
- When will service be available? Obtain an expected connection and commissioning date, plus the arrangement that applies if the permanent connection is late.
- Who owns and maintains the pipes? Clarify the boundary between utility-owned infrastructure and private or shared pipes, tanks, pumps or meters.
In Ireland, Uisce Éireann’s developer information includes water-supply and wastewater-treatment capacity registers and connection guidance. A register can show whether a treatment plant or network appears to have capacity, but it is not a project-specific connection acceptance. Ask the utility to confirm the particular development, phase, design and date.
Private or shared supplies need extra checks
If the project uses a well, borehole, storage tank, private treatment plant or shared network, request the operating agreement and technical information. Find out who samples or tests the water, maintains pumps and treatment equipment, pays electricity and emergency call-outs, and collects contributions from each property. A private arrangement can be workable, but its reliability depends on a named operator, funded maintenance and a clear replacement plan.
Check foul sewage and rainwater as different systems
“Sewer connection” can conceal two separate drainage questions. Foul sewage carries toilet and household wastewater. Surface-water drainage carries rain and runoff from roofs, roads and paved areas. They may use different pipes, destinations, owners and maintenance regimes.
Trace foul drainage from each home to treatment
Request the drainage strategy, connection application and acceptance or approval documents. Identify the route from the property through the estate and onward to a public sewer, private sewer, pumping station, septic system or treatment plant. Ask whether the connection has been commissioned for the phase, whether downstream capacity has been confirmed, and what works remain.
If pumps are involved, establish who supplies electricity, tests alarms, responds to failures and pays for replacement equipment. For private treatment or septic systems, ask who inspects the system, removes sludge, maintains the outfall and carries legal responsibility for compliance. Obtain the maintenance contract or management-company obligations rather than relying on a verbal promise.
Trace surface water separately
Determine where roof, road and garden runoff goes: an adopted surface-water sewer, a watercourse, an attenuation pond, infiltration systems, a private drainage field or a combination. Confirm that the receiving system has approval and capacity for the project’s impermeable area and that required flow controls are installed.
Ask who maintains gullies, pipes, swales, ponds, tanks, flow controls and access routes. A pond that looks complete may still lack a maintenance regime or safe access for inspection. Check how flooding incidents are reported and who pays for desilting, pump replacement and repairs.
Understand ownership boundaries
Responsibilities can change along the route. The House of Commons Library briefing “Sewerage connections for new housing developments (England),” published 27 May 2026, explains that property owners may remain responsible for some drains while the water company maintains adopted lateral drains. The exact boundary depends on the local legal framework and adoption status, so obtain a plan or written schedule that marks each responsibility.
Do not assume England’s arrangements apply elsewhere. Planning, building regulations and water services are devolved in the UK, and other countries use different authorities and adoption rules.
Check roads in three stages: access, completion and maintenance
A development can have a legal access route while its internal roads remain unfinished or privately maintained. Check these as separate issues.
1. Confirm lawful access and the approved layout
Compare the road and junctions being built with the approved access plan. Confirm that the route used by residents, emergency services, refuse vehicles and construction traffic is the approved route and has the necessary highway or road authority approvals. A road shown on a planning drawing is not automatically a public road.
Ask the relevant authority whether any separate consent is required for work affecting a public road. NSW Department of Planning, Housing and Infrastructure guidance notes that road-related approvals can be separate from development consent; use that as a prompt to check the local equivalent rather than assuming one approval covers everything.
2. Verify construction and handover status
Request a written status for each road serving your phase: complete, under construction, awaiting inspection, in an adoption process, or privately maintained. Ask for the completion certificate, inspection record, list of outstanding works and any bond or security securing completion.
Inspect the site after rain and at busy times. Look for unfinished footways, missing lighting, open drainage works, temporary surfaces, restricted turning space and unsafe crossings. A sales plan may show the final layout even when the current route is temporary.
3. Establish long-term maintenance
Obtain the adoption agreement or private maintenance covenant. It should identify who repairs carriageways and footways, replaces street lights, cleans gullies, clears snow or hazards where relevant, and pays for major resurfacing. If a management company is responsible, ask how charges are calculated, whether reserves are required, and what happens if owners do not pay.

Confirm the status with the highway or road authority yourself. Do not infer public maintenance from a road name, a local map or the presence of street lights. The legal effect of adoption and the documents used to record it depend on jurisdiction.
Test public-transport promises against actual operations
A transport assessment is evidence to inspect, not a guarantee that a dependable service will operate. Planning documents may model a future route or frequency that depends on funding, patronage, road completion or a later phase.
Check the service people can use now
- Find the nearest stops to the actual phase, not only to the edge of the site.
- Check current timetables for commuting periods, school travel, evenings and weekends.
- Measure the walking route, including crossings, gradients, lighting and accessible surfaces.
- Check whether construction diversions or incomplete roads make the nominal route impractical.
- Ask about vehicle capacity, reliability history and connections to rail, town centres, schools and health services.
Use the current operator timetable and ask the operator or transport authority to confirm any announced changes. A promise to “provide a shuttle” should name the operator, start date, operating period, route, funding source and contingency if the service is withdrawn.
Read the transport assessment critically
England’s official guidance on travel plans and transport assessments identifies the issues worth checking: public-transport provision and frequency, walking and cycling access, road and junction capacity, safety, service changes, cumulative effects from committed development and mitigation measures. Look for the baseline date and the assumptions used for other approved or committed projects.
Recommended Free Tools
Separate measures that are funded and scheduled from those described as aspirations. A contribution secured by an agreement is stronger evidence than a conceptual route, but still verify when and how it will be delivered. Ask whether the service depends on a road, bridge, stop or footway that is not yet complete.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Use an evidence hierarchy
When statements conflict, give greatest weight to records that identify the exact site, phase and date. The following order is a practical guide.
| Evidence | What it can establish | What it cannot establish by itself |
|---|---|---|
| Written confirmation from the responsible utility or authority | Current connection, capacity, ownership or approval for the specified phase, if the letter is specific | That unrelated private infrastructure or later phases are ready |
| Signed connection, adoption or maintenance agreement | Allocated responsibilities, conditions and delivery obligations | That every physical work has been completed unless completion is recorded |
| Completion certificates, inspection records and discharged conditions | That identified works passed the relevant inspection or condition process | Future reliability or capacity beyond the approved scope |
| Approved plans and infrastructure statements | The design, route and commitments assessed in the approval | Live operation, commissioning or public adoption |
| Current operator timetable | Published service at the time checked | Unfunded future routes or long-term continuation |
| Marketing material, nearby mains or a proposed route | A lead for further investigation | Connection acceptance, capacity, adoption or funded operation |
Keep copies of every response and record the date, contact, reference number, phase and plot covered. A statement that says “capacity available” without identifying the network point, design demand or validity period is incomplete evidence.
A practical verification sequence
- Identify the exact phase. Mark the plots, access roads and infrastructure intended to serve them. Ask whether the phase can be occupied independently or relies on later works.
- Collect and read the planning file. Note all infrastructure conditions, phasing triggers, approved routes and amendments. Confirm which conditions have been discharged.
- Contact the water provider. Obtain source, connection, capacity, reinforcement, commissioning, ownership and interim-supply details in writing.
- Contact the wastewater or drainage authority. Trace foul and surface water separately, confirm treatment or discharge capacity, and identify private sections and maintenance duties.
- Contact the highway or road authority. Verify access approvals, road completion, inspection status, adoption or private maintenance, bonds and unfinished works.
- Check public transport independently. Compare the transport assessment with current timetables, safe walking routes, capacity and funded future measures.
- Inspect the site. Photograph unfinished roads, drainage features, temporary connections, missing lights and barriers. Compare what exists with the approved plans.
- Resolve conflicts before exchange or completion. Ask for a dated written answer, revised programme, contract protection or independent advice where evidence does not match the sales claim.
Red flags that justify delay or specialist advice
- The seller will not name the water, sewerage, highway or transport authority responsible for the relevant phase.
- Connection depends on future network reinforcement with no funded programme or completion trigger.
- Occupation is permitted before promised roads, drainage or utility works are demonstrably complete.
- A private pump, treatment plant, road or drainage system has no maintenance agreement, reserve fund or emergency contact.
- Plans show infrastructure for the whole scheme, but the documents do not state what serves the phase being sold.
- Road adoption is described as “expected” without an agreement, inspection record or bond details.
- A transport improvement is presented as certain even though no operator, funding or start date is identified.
- Planning records, utility responses and the physical site contradict one another.
Escalate to a jurisdiction-specific conveyancing solicitor, civil engineer or infrastructure adviser when ownership boundaries, private systems, adoption terms or delayed reinforcement could affect your legal rights or ongoing costs. Professional document review should supplement—not replace—written confirmation from the responsible provider.

How to record your decision
Create one page for each system with five fields: current status, evidence and date, outstanding work, responsible party, and consequence if delayed. Mark each item as operational, under construction with a dated commitment, proposed only or unresolved. Do not treat “proposed only” as operational when deciding whether the property meets your needs.
Before committing, make sure the contract and disclosure documents match the infrastructure status you were shown. If a service is essential to occupation, ask what remedy applies if it is not delivered on time. The answer should be specific enough to enforce, not simply a promise that the developer will “liaise with the authorities.”
