System runs
The fan, replacement fan, motor, controller or temporary operational route runs without immediate trip or failure during agreed testing.
Commercial agreement overview
Lower upfront risk, clear payment when the working outcome is achieved
This page sets out a practical framework for commercial kitchen fan work. It is not a final solicitor-approved contract. CKFS should have this wording reviewed before using it as binding terms.
Recommended contract principle: the customer pays a deposit or agreed pre-authorisation first, then the balance becomes due when CKFS achieves the agreed operational restoration criteria or supplies an agreed equivalent-or-better solution.
Payment trigger
Operational restoration criteria
The payment trigger should be written into each accepted quote so the customer knows what counts as success.
Kitchen can trade
Extract airflow is restored enough for the agreed commercial use, subject to unrelated duct, canopy, gas, access or electrical defects.
Equivalent or better route
Where replacement is used, the supplied solution should be suitable for the agreed duty and at least equivalent in practical performance to the replaced route.
Suggested wording
Balance payment clause
This is draft commercial wording for solicitor review, not final legal advice.
Where CKFS achieves Operational Restoration, or supplies and installs an agreed replacement or alternative fan solution with equivalent or greater rated suitability for the agreed duty, the Customer accepts that the agreed balance is immediately due.
Operational Restoration means that the agreed fan route runs during completion testing and the kitchen can resume ordinary commercial operation, subject to any exclusions, unrelated defects, site conditions or third-party works recorded before or during attendance.
Customer protection
No-solution route
The customer should not feel trapped into paying full balance where CKFS cannot offer a viable route.
- If no viable working solution route is identified, CKFS confirms the position in writing.
- Repair labour, callout, access and third-party costs should be separated clearly.
- Any no-solution or no-fix term should be stated on the accepted quote before attendance.
- Unrelated site defects should not remove payment due for completed agreed work.
Evidence
Completion evidence that makes payment easier to prove
Photos
Fan, motor, controller, access and installed solution photos.
Test notes
Running test, airflow proving status, controller status and fault observations.
Job sheet
Customer, site, fault, agreed route, exclusions, parts and completion time.
Acceptance
Signature, written approval, payment link acceptance or recorded use after completion.
Quote acceptance
What each accepted quote should confirm
- Customer name, company, authority and billing details
- Site address, access constraints and attendance window
- Reported fault and chosen response level
- Deposit, pre-authorisation, balance and due date
- Operational restoration criteria and exclusions
- Evidence pack and dispute route
Payment recovery
Keep it clear and proportionate
A clear accepted quote, evidence pack and written completion record are usually stronger than broad terms alone. Late payment interest, recovery costs and court claim routes should be handled in line with the final solicitor-approved terms and current UK rules.
