1. Introduction & Multi-Domain Ownership

These terms and conditions apply between you, the User/Customer of our services, and Misfuelled Car Fixer Ltd, the owner and operator of this digital network. Please read these terms carefully before instructing us, as they directly impact your legal rights.

If you do not agree to be bound by these terms, you must cease using our websites and services immediately.

For the avoidance of doubt, Misfuelled Car Fixer Ltd holds full legal ownership, brand authority, and operational control over the following network of regional domains and all associated sub-domains:

Any service booked, deposit paid, or instruction issued through any of the websites listed above is subject to these master Terms and Conditions.


2. Definitions & Interpretations

Within this agreement, the following terms are defined as:

  • "Misfuelling" or "Wrong Fuel": The accidental or intentional introduction into a vehicle's mechanical system (including but not limited to motorbikes, passenger cars, light commercial vans, lorries, and HGVs) of any fuel, liquid, or chemical substance that is not explicitly specified for use in that vehicle by the manufacturer. This includes putting petrol into a diesel tank, diesel into a petrol tank, or introducing AdBlue (Diesel Exhaust Fluid / DEF), water, oil, screenwash, or contaminated biofuels into any part of the vehicle’s fuel, exhaust, or cooling network.
  • "AdBlue Contamination": The presence of AdBlue/DEF in a fuel storage tank or fuel delivery network. AdBlue is a corrosive, water-based urea solution that rapidly crystallizes when exposed to fuel lines, high-pressure fuel pumps, injectors, and engine combustion chambers.
  • "The Service": The technical evacuation, extraction, and clean flushing of the contaminated fuel tank/system at the job location, followed by the safe transport and certified environmental disposal of the hazardous chemical waste.


3. Scope of Service: What is Included & Excluded

Misfuelled Car Fixer Ltd provides emergency on-site fuel decontamination services. To avoid ambiguity, the operational boundaries of our standard call-out rate are strictly defined below:

Included within the standard call-out rate:

  • Fuel Evacuation: The technical suction, removal, and evacuation of contaminated fuel/AdBlue mixtures from the vehicle’s main fuel tank using mobile fuel drainage equipment.
  • Environmental Waste Disposal: The safe handling, transport, and certified environmental disposal of hazardous contaminated fuel in full compliance with UK Environment Agency guidelines and hazardous waste regulations.
  • Standard System Flush (Where Applicable): Basic low-pressure line purging of immediate fuel lines where standard equipment allows without mechanical dismantling.

Excluded from the standard call-out rate (Billed Separately):

  • Fresh Priming Fuel: The physical cost of clean fuel (petrol or diesel) required to restock, prime, or restart the engine following a drain.
  • Replacement Mechanical Parts: The cost or installation labor for new components, including primary/inline fuel filters, glow plugs, relays, high-pressure fuel pumps, or injectors damaged by fuel contamination or crystallization.
  • Chemical Additives: The cost of specialized fuel system additives, lubricity treatments, injector cleaners, or chemical flushes.
  • Battery Support & Recharging Services: 12V battery jump-starting, extended trickle charging, battery testing, or replacement. If a vehicle’s battery becomes depleted prior to or during the priming process, auxiliary battery support is not guaranteed and may incur additional charges if available.
  • Auto-Electrical & ECU Interventions: Diagnostic scanning, fault code clearing, central locking resets, key fob re-synchronization, immobilizer clearing, or auto-electrical repair work.
  • Extended System Bleeding & Mechanical Diagnostics: Additional labor required to manually bleed complex air-locked fuel systems, purge high-pressure common-rail injectors, dismantle component lines, or rectify pre-existing mechanical failures caused by driving or starting the engine on contaminated fuel/AdBlue prior to our arrival.

Note: All fresh fuel, parts, chemical additives, or specialized secondary labor provided on-site are subject to additional charges, which will be billed separately and added to the final payable balance.


4. Limitation of Liability, Pre-Existing Ignitions, AdBlue Risks & Secondary Drains

Modern automotive vehicles rely on complex electronic networks, sensitive high-pressure fuel delivery systems, and precision components. The introduction of incorrect fuel—and particularly AdBlue (DEF)—carries catastrophic mechanical risks, particularly if the engine was cranked or started prior to a fuel drain.


Critical Mechanical & Electrical Liability Disclaimer

Misfuelled Car Fixer Ltd and its attending technicians operate on a best-endeavors basis. While we exercise reasonable skill and care, we accept zero financial, legal, or operational liability for any vehicle damage, component failure, electronic malfunction, or secondary fault occurring prior to, during, or following a roadside fuel drain.

A. Pre-Existing Engine Starts, Trapped Contaminants & Multi-Stage Drain Risks

  1. Pre-Service Engine Ignitions: Starting the engine, turning the ignition key to the accessory position, or attempting to drive a vehicle with contaminated fuel or AdBlue forces the fluid out of the tank and directly into the high-pressure fuel pump, common-rail lines, injectors, filter housings, and secondary return circuits.
  2. Trapped Contaminated Fuel & Secondary Drains: The Customer acknowledges that in certain fuel system designs (such as saddle tanks, dual-chamber reservoirs, or complex anti-siphon networks), residual contaminated fuel or AdBlue can remain trapped in fuel lines, filters, or sub-tanks following an initial drain. Once the vehicle is started, driven, or tilted, this trapped fluid may circulate back into the main system, causing temporary engine hesitation, stalling, or requiring the vehicle to undergo a secondary fuel drain or extended line purge.
  3. Scope of Roadside Drain: A standard roadside fuel drain extracts contamination accessible at the time of service. It does not and cannot guarantee that trapped AdBlue crystallization, pump scoring, or line contamination already circulated through the system prior to our arrival has been 100% eliminated in a single pass.
  4. Subsequent Breakdowns & Component Failure: We accept zero liability for subsequent engine stalling, power loss, component failure (e.g., injector seizure, high-pressure pump failure), or vehicle breakdowns occurring after a completed tank drain where trapped fuel circulates or where the customer started/ran the engine prior to our service.

B. Mandatory Right of Inspection, Secondary Treatment & Refusal of Access

  1. Duty to Allow Inspection & Rectification: In the event that a vehicle experiences operational difficulties, stalling, trapped fuel circulation, or a breakdown following our service, the Customer MUST grant Misfuelled Car Fixer Ltd and its technicians immediate, reasonable, and unhindered physical access to inspect, test, diagnose, perform a secondary drain/bleed if necessary, and attempt to rectify the issue roadside or at the vehicle location.
  2. Refusal of Access: If the Customer refuses, denies, or prevents the technician from touching, inspecting, diagnosing, flushing, or working on the vehicle upon arrival or at a follow-up roadside incident, Misfuelled Car Fixer Ltd is immediately and automatically discharged from all further operational duties, warranties, and financial liabilities.
  3. Forfeiture of Claims: Refusing technician access, engaging in aggressive conduct, or preventing on-site diagnostic investigation/secondary flushing constitutes a material breach of contract by the Customer. The Customer immediately forfeits all rights to deposit refunds, service fee chargebacks, or secondary repair/compensation claims.

C. Battery Discharge & Electronic Reset Disclaimer

Attempting to purge contaminated fuel, turn over an engine, bleed fuel lines, or run low-pressure lift pumps naturally draws power from the vehicle’s 12V battery. Misfuelled Car Fixer Ltd takes zero responsibility for pre-existing or post-drain battery depletion, voltage drops, dead cells, or subsequent electronic glitches triggered by low voltage—including central locking failure, immobilizer reset issues, key fob desynchronization, electric window resetting, diagnostic re-coding, or dashboard fault codes.

D. Consequential & Indirect Loss Exclusion

Under no circumstances shall Misfuelled Car Fixer Ltd be liable for any indirect, special, incidental, or consequential damages arising out of or in connection with the provision of our services. This includes, but is not limited to: loss of income, loss of business, alternative transport or car hire costs, taxi fares, towing fees, third-party diagnostic fees, main dealer reset charges, or secondary repair bills incurred by the customer following our visit.

E. Cap on Financial Liability

To the maximum extent permitted by applicable UK law, the total cumulative liability of Misfuelled Car Fixer Ltd for any direct loss, damage, or claim arising from or related to our service shall be strictly limited to a sum equal to the total amount actually paid by the customer to Misfuelled Car Fixer Ltd for the specific service call-out in question.

F. Notice Period for Disputes & Third-Party Works

Any alleged damage, secondary fault, or operational dispute arising from our service must be reported in writing to info@misfuelledcarfixer.co.uk within forty-eight (48) hours of the service being completed.


  If a third party, recovery company, main dealer, or independent mechanic undertakes diagnostic, mechanical, or electrical work on the vehicle prior to Misfuelled Car Fixer Ltd being given a reasonable opportunity to inspect the vehicle, Misfuelled Car Fixer Ltd shall be automatically released from all potential liability or compensation requests.


5. Fuel Filter, Battery Care & Mandatory Post-Service Recommendations

Following a fuel contamination or AdBlue event, residual chemical pollutants, particulates, and water droplets routinely remain trapped inside the dense filtration fibers of a vehicle’s primary fuel filter.

Mandatory Technical Recommendations:

  1. Immediate Fuel Filter Replacement: We strongly recommend that all customers have their primary fuel filter replaced immediately following our decontamination service. Trapped contaminants or AdBlue crystals within an old filter can restrict fuel flow, cause engine stalling, or recirculate microscopic abrasive debris back into high-pressure injectors.
  2. Immediate Battery Recharging: If your vehicle's 12V battery experienced significant voltage drop during starting attempts, you must immediately connect the vehicle to a suitable charger or undergo an extended battery recharge.
  3. Customer Assumption of Risk: Misfuelled Car Fixer Ltd accepts zero financial or legal liability for secondary mechanical breakdown, fuel delivery starvation, injector failure, or electronic glitches that occur as a direct or indirect result of the customer delaying or failing to carry out a recommended fuel filter replacement post-service.


6. The "No Start, No Fee" Policy Basis & Exclusions

Our "No Start, No Fee" policy applies exclusively to standard, un-ignited fuel extraction scenarios where no underlying mechanical, structural, or chemical component damage exists prior to our arrival.

Conditions Under Which "No Start, No Fee" Becomes Void:

If our technician successfully executes the technical evacuation, line flush, and fuel decontamination, but the vehicle subsequently fails to start, run, or turn over smoothly, the full agreed service fee remains strictly due and payable in full under any of the following circumstances:

  1. Pre-Service Ignitions & AdBlue Circulation: The engine was started or cranked prior to our arrival, resulting in internal component scoring, high-pressure pump air-locks, or AdBlue crystallization in the injectors/lines.
  2. Battery Depletion & Voltage Loss: The vehicle fails to start or crank purely due to a drained, flat, or degraded 12V battery or immobilizer lockouts.
  3. Air Ingress & Extended Bleeding Issues: Persistent air locks within complex high-pressure fuel systems that require secondary mechanical dismantling or workshop equipment to clear.
  4. Non-Fuel Auxiliary Faults: Pre-existing mechanical or electrical faults, blown fuses, faulty starter motors, failed glow plugs, or immobilizer issues unrelated to the physical presence of fuel in the tank.
  5. Customer Refusal of Rectification: The customer refuses to allow the technician to complete priming, diagnostic checks, or roadside investigation.


7. Booking Procedures, Deposits, Payment Terms & Cancellation Policies

A. Non-Refundable Booking Deposit

  • Mandatory Deposit: A non-refundable booking deposit (including standard deposits of £100 or more) is strictly required from all customers to confirm an emergency service slot and formally authorize the physical routing/dispatch of a technician to your coordinates.
  • Allocation of Deposit: Deposits cover immediate business overheads, including technician allocation, travel time, vehicle fuel expenses, dispatch operations, and the reservation of emergency service availability.
  • 100% Non-Refundable Nature: Once an emergency technician has been dispatched, or once service has commenced, the deposit is strictly 100% non-refundable under all circumstances.

B. Customer Cancellation or Refusal of Service

If the Customer cancels the service after a technician has been dispatched, or refuses to permit the technician to inspect, diagnose, work on, or complete the job upon arrival or during a roadside follow-up, the deposit will be retained in full, and the Customer remains fully liable for all completed labor, fuel supplied, and travel expenses incurred.

C. Payment Obligations & Completion of Service

  1. Immediate Payable Balance: The total agreed balance (including call-out fee, fuel drain charge, and any fresh fuel supplied) becomes strictly due and payable immediately upon completion of the fuel drain on-site, prior to the vehicle leaving the immediate presence of the technician.
  2. Promise of Payment / Deferred Payment: The customer has no right to withhold payment while driving to an off-site location (such as a filling station). Driving away without settling the agreed service balance constitutes non-payment and a material breach of contract.
  3. Debt Recovery: Misfuelled Car Fixer Ltd reserves the right to pursue full recovery of unpaid balances, including administration fees, legal recovery costs, and interest under the Late Payment of Commercial Debts Regulations.


8. Absolute Right of Refusal

Misfuelled Car Fixer Ltd maintains an absolute right to refuse service, cancel a live dispatch route, or immediately cease an ongoing on-site extraction/investigation for any of the following reasons:

  1. The customer, or anyone accompanying the customer, behaves in a threatening, aggressive, abusive, or demeaning manner toward any employee, technician, or operator.
  2. The customer refuses to permit the technician to perform essential diagnostic, safety, or rectification checks on the vehicle.
  3. The customer flatly refuses to process the required mandatory booking deposit or clear outstanding service balances.


9. External Hyperlinks & External Web Content

Misfuelled Car Fixer Ltd exercises zero editorial control, assumes no legal responsibility, and rejects all liability for the content, privacy policies, or accuracy of any third-party web portals hyperlinked across our regional domain network.

  • Mandatory Deployment: Attending technicians and mobile recovery engineers are equipped with audio-visual recording devices (body cameras). Technicians may activate BWV recording upon arrival at the service location, during the initial vehicle inspection, throughout the fuel drainage and priming process, and during all customer interactions or diagnostic procedures.
  • Lawful Basis & Legitimate Interests: Audio and video recording is conducted under the lawful basis of legitimate interests (GDPR Article 6(1)(f)), specifically for:
  • Protecting technician safety and preventing physical, verbal, or aggressive abuse.
  • Documenting the pre-existing mechanical, electrical, and cosmetic condition of the vehicle prior to work commencing.
  • Capturing diagnostic evidence of engine starts, ignition attempts, trapped fuel contamination, battery conditions, and post-service engine restarts.
  • Resolving payment disputes, chargeback claims, or alleged vehicle damage claims.
  • Customer Acknowledgment & Consent: By requesting our services, authorizing dispatch, paying a deposit, or permitting a technician to work on your vehicle, you acknowledge and agree that your interaction, voice, and vehicle may be recorded on camera.
  • Refusal or Interference: If a Customer demands that a technician disable their recording equipment, behaves aggressively toward camera equipment, or attempts to prevent recording during an active dispatch or roadside recovery, Misfuelled Car Fixer Ltd reserves the absolute right to refuse or immediately terminate service under Section 8 (Absolute Right of Refusal). In such circumstances, all booking deposits and incurred call-out costs remain strictly non-refundable.
  • Data Storage, Privacy & Evidentiary Use: All recorded footage is securely stored, encrypted, and processed in accordance with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018. Footage will be retained for as long as reasonably necessary to fulfill dispute resolution or legal requirements and may be submitted as primary evidence to banking institutions (for chargeback disputes), insurance companies, legal representatives, debt collection agencies, or law enforcement authorities.


Subcontractor & Agent Clause:

If your emergency fuel drain was allocated to, and carried out by, an independent third-party agent, localized recovery company, or external network mechanic working on our behalf, you must raise your complaint directly with that specific service provider. Misfuelled Car Fixer Ltd is unable to intervene in legal or financial disputes arising from independent contractor jobs where service contracts were executed directly by third parties.
