What Is A Leakage Allowance And When It Applies
A leakage allowance is a bill reduction granted after you repair a hidden leak that pushed your metered consumption abnormally high. It usually applies to customer-side pipework: the external supply pipe between the boundary and your internal stop tap, and concealed pipes within walls, floors or foundations. It does not cover normal consumption, accidental use, or negligence.
Qualifying examples include a burst under a driveway or a corroded joint beneath a slab. Non-qualifying examples include hoses left running, pond top-ups, irrigation, or faulty appliances. Each water company sets its own rules and time limits, so always check current guidance for Thames Water, Affinity Water and SES Water.
- Confirm who owns each pipe section: leak responsibility.
- Prove continuous flow with a simple isolation test: water meter night test.
If you suspect a mains or concealed internal leak, book a same-week survey with Track A Leak. Fast confirmation and clear evidence protect your claim window.
Do You Qualify? Quick Eligibility Checks For Thames, Affinity And SES Water
Thames Water generally considers concealed leaks on customer pipework, repaired promptly once discovered. Expect deadlines from either the bill spike or discovery date, and a preference for first-time events. Smart meters may show constant flow; see constant flow alerts to support your claim.
Affinity Water typically requires proof of a leak on the supply or hidden internal pipework and evidence that the repair was completed within their stated timeframe. Clear before/after meter data is key.
SES Water criteria often specify supply pipes and concealed internal runs as eligible. Surface taps, appliances and negligence are excluded. In all cases, run a night test before repair and keep dated photos and invoices. Check the latest rules on each company’s website before you submit.
Evidence You’ll Need: The Documents That Make Claims Easy To Approve
Submit a simple, dated evidence pack:
- Sequential meter readings with timestamps: before repair, immediately after isolation, and after repair. If possible, show the meter serial number matching your account.
- Smart meter exports: constant flow alerts or interval data around discovery, isolation and repair.
- Clear photos of the meter face (avoid glare, keep the camera square).
- Repair proof: repair date, method/materials, and photos of the exposed pipe or failed joint.
- Invoice or job sheet from the contractor.
- Professional report stating leak location, probable cause, test methods and estimated flow, plus a photo log and sketches. See: prove a concealed water leak.
- Checklist: night test results; dated meter photos; smart meter data (if available); repair invoice; photos during repair; professional report; simple site plan or notes on the pipe route.
- Tip: use your phone’s timestamp and take meter photos before isolation, during isolation and after the repair.

Why A Professional Report Speeds Approvals
Case handlers look for three things: the exact leak location on eligible pipework, a cause consistent with leakage (not use), and confirmation the repair stopped the flow. A structured, independent report from Track A Leak answers these in one bundle, with photos and meter logs.
- Common mistakes: vague locations (“somewhere under floor”), missing repair date, no meter proof, or only a plumber’s invoice with no diagnostics.
- We deliver a same-day PDF with findings, methods and evidence. Learn more about our leak detection.
Step-By-Step: Apply To Thames Water After A Hidden Leak
- 1. Before you apply: isolate to test. Close the internal stop tap overnight and record meter readings at the start and end of the test. Keep clear, dated photos. If flow stops when isolated, the leak is on your side.
- 2. Repair and document. Photograph the exposed pipe or joint during repair. Keep dated invoices and a short note of what was fixed and where.
- 3. Capture after-repair evidence. Take a new meter photo and confirm no constant flow. If you have a smart meter, export interval data. Use our constant flow checklist.
- 4. Complete the form. Be precise: leak location relative to the boundary and internal stop tap, repair date, method, and who carried out the work. Upload meter photos and any report.
- 5. After submission: you’ll usually hear back within weeks. Save a PDF copy of your claim, note your reference, set a follow-up for 10–14 days, and respond quickly to any requests.
Step-By-Step: Apply To Affinity Water
Pre-check eligibility: the leak must be on your pipework and concealed. Repair it within Affinity’s time window once discovered. Gather sequential meter readings, night test logs, dated repair photos and an invoice.
Attach a professional report that pinpoints the location and confirms the repair stopped the loss. After submission, keep logging meter reads for a week to show usage is back to normal. Monitor your next bills to verify the adjustment and contact Affinity if it isn’t applied as expected.
Step-By-Step: Apply To SES Water
Be specific: describe the exact position, e.g. “between boundary stop tap and internal stop tap under the front drive” or “concealed copper in kitchen slab”. Provide clear dates for discovery and repair, plus photos of the exposure and fix.
Upload meter evidence before and after the repair and a professional report if available. Typical reviews take a few weeks. If timelines slip, follow up politely with your reference number and reattach the key documents.

Special Cases: Shared Supplies, Tenants/Landlords And Empty Properties
On shared supplies, coordinate with neighbours. Collect meter reads for each party, note the supply route if known, and explain how you isolated sections during testing. If one branch shows continuous flow when others are closed, document it.
For tenancies, the named bill payer usually submits the claim, but managing agents can provide documents. Landlords should keep a simple file: reads, report, repair invoice and photos.
For empty or second homes, prove no beneficial use with dated photos, occupancy statements and continuous-flow meter data. The aim is to show the excess was leakage, not consumption.
What Allowances Cover—And What They Don’t
Most allowances reduce water charges to a normal level for the period of the leak. Some also adjust wastewater if the leaked water did not enter the sewer. Limits apply: one-time allowances, backdating windows and exclusions for negligence or appliance faults are common.
Expect to provide proof that the leak is repaired and that consumption returned to typical levels. Leakage allowances are separate from insurance. They do not fund finding or fixing the leak, or reinstatement. Those costs may fall under “trace and access” or property damage cover depending on your policy.
Turn Evidence Into A Winning Claim: Our Leak Detection Process
Track A Leak uses non-destructive diagnostics—acoustic listening, tracer gas, correlation and thermal imaging—to pinpoint hidden failures. We map the route, mark the location and estimate loss with meter-based checks.
Your same-day deliverables: a clear report with location, cause, test methods, a photo log and repair guidance, plus before/after meter data. This is exactly what claim handlers need to approve an allowance quickly.
We cover London and the Home Counties (Surrey, Kent, Essex, Berkshire, Buckinghamshire and Hertfordshire) with rapid appointments. Ready to move from suspicion to proof? Get a quote and book your survey today.
FAQs
How fast do I need to repair the leak to qualify?
Repair as soon as you discover it. Most companies set strict time limits from discovery or from the bill spike, so act quickly and keep dated evidence.
Do I need a professional report to claim?
Not always, but it speeds approval. A structured, independent report with photos and meter logs answers the handler’s key questions in one go.
Will wastewater charges be adjusted too?
Often, if the leaked water didn’t reach the sewer. Policies vary by company, so check current guidance.
What if my meter is in a shared pit or I’m on a shared supply?
Coordinate readings with neighbours and document isolation tests for each branch. Provide a clear explanation and supporting photos.
Can I claim if an appliance failed or a hose was left running?
Generally no. Allowances target hidden leaks on pipework, not accidental use or appliance failures.
How do I challenge a refused allowance?
Reply with your reference, a concise summary of facts, and any missing evidence (meter sequence, repair proof, report). Ask for a review and an expected timescale.
