The leak is repaired but the supplier case is still open
If the private leak has been repaired but supplier letters continue, contact the supplier using the original case reference and ask what remains outstanding. A completed repair, a closed supplier case and a billing adjustment are separate outcomes. Keep the repair evidence and current observations clear rather than assuming every new letter proves the repair failed.

Discuss your plumbing workMatch the letter to the correct property and case
Check the address, reference, date and description of the reported concern. A letter may relate to an earlier investigation, another meter or a different supply arrangement. Compare it with the correspondence that led to the repair. Where a property has several accounts or dwellings, identify which one the supplier is referring to before sending a broad bundle of documents.
Record when the repair was completed and when you informed the supplier. A later arrival date does not necessarily mean a letter was generated after the update reached the relevant team. Ask whether the case has received your information and whether the current communication requires a specific action. Keep the reply rather than relying on an assumption about postal or processing delays.
Separate completion reporting from a leak allowance request
Thames Water’s home-leak guidance asks customers to tell it when a leak has been fixed. That enables the supplier to update its repair records. A request to adjust charges for lost water is another process and may need its own information. Do not assume that sending an invoice to one department completes every related task.
Ask which process the outstanding letter concerns: repair confirmation, further inspection, consumption evidence or billing. Use the appropriate reference for each. Our leak-allowance evidence guide covers a claim file; this article concerns an open repair case. Keeping those purposes distinct helps avoid repeatedly submitting the same document when the supplier is actually asking a different question.
Provide evidence that identifies the work
A useful repair record states the property, date, location and pipe or fitting repaired. It should distinguish a completed repair from investigation only or a temporary measure. If the contractor’s invoice is too general to show that, ask for a factual clarification. Do not alter the contractor’s document or add technical conclusions they have not confirmed.
Include relevant completion checks and any recommendation for further work. If the contractor reported a second possible leak, the supplier needs to know that the original repair may not settle the entire concern. Conversely, a recommendation to consider future renewal is not automatically evidence of an active remaining leak. Preserve the wording and ask the contractor to explain uncertain distinctions before presenting them as a conclusion.
| Outcome | Useful confirmation |
|---|---|
| Private repair completed | Contractor identifies the repaired section, completion date and relevant checks. |
| Supplier case updated | Supplier confirms whether further inspection or evidence remains outstanding. |
| Billing query resolved | Supplier explains the separate adjustment decision and the period it covers. |
Compare current evidence with the original alert
If safe, reliable readings or supplier usage data are available, keep the dates and identify what period they cover. Ask the supplier whether enough post-repair information is available for its assessment. A bill issued shortly after the repair may still include consumption from before it, so the total amount alone is not a useful test of success.
Do not turn this into repeated isolation experiments or enter a meter chamber to create evidence. Where readings are unavailable, say so and ask how the supplier will assess the update. If there is continuing visible leakage, new damage or another clear symptom, report that promptly as a current issue rather than waiting for the correspondence to be resolved.
Clarify any inspection or further work request
The supplier may need further information or a check before it closes its case. Ask what is required, who will arrange it and whether access is needed. Do not assume that a private contractor can sign a supplier-specific form or certification unless the contractor is authorised and competent for that particular requirement.
Where the supplier’s conclusion differs from the repair contractor’s findings, ask both to identify the evidence and exact pipe section involved. A short written exchange may reveal that they are discussing different parts of the supply. If the disagreement remains, seek the relevant technical or consumer advice. Repeatedly commissioning work without understanding the outstanding concern can waste money and still leave the record unresolved.
Keep a concise closure record
Maintain a one-page chronology of the alert, investigation, repair, completion notification and supplier response. Save the final acknowledgement when received and identify any billing matter that remains separate. This is useful if another letter arrives or a new managing agent takes over. It should reflect what each party confirmed, not an optimistic summary that all matters are settled.
If a further private plumbing assessment is needed, give Loyal Plumbers that chronology and the current symptoms. Explain what the earlier repair addressed and what the supplier now wants clarified. We can discuss the private investigation or repair scope, while the supplier controls its own case and billing decisions. No private contractor can guarantee that a particular document will automatically close the supplier’s file.
Common questions
- Does another letter mean the repair failed?
- No. Check the reference, issue date and outstanding requirement. It could concern processing, evidence, a separate issue or a continuing problem that needs investigation.
- Does applying for an allowance close the repair case?
- Do not assume so. Ask the supplier to confirm whether completion reporting and the billing adjustment are both recorded and whether either needs further information.
- Can a plumber guarantee the supplier will close the case?
- No. A plumber can document the work and findings within their scope. The supplier decides what it requires to update its own records.
