How Our Tools Work (Important Information)

ChangeCar.com brings together a collection of independent, self-serve tools designed to help UK drivers explore the potential costs, trade-offs, and considerations involved in owning, running, repairing, financing, or replacing a vehicle. These tools are intended to help users think through different scenarios by entering their own information and assumptions, based on their individual circumstances, priorities, and requirements.

All calculations, estimates, and outputs generated by these tools rely entirely on the information provided by the user, along with generalised assumptions and commonly available reference data. The accuracy, relevance, and usefulness of any result will therefore depend on the completeness, accuracy, and appropriateness of the inputs entered. ChangeCar.com does not verify user inputs, nor does it assess whether any assumptions selected are suitable for a particular individual, vehicle, or situation.

The tools available on this page cover a wide range of common ownership questions, including repair versus replacement decisions, ongoing ownership and running costs, fuel and commuting expenses, electric vehicle considerations, insurance-related topics, and vehicle finance comparisons. They are designed to support understanding, comparison, and exploration of options, rather than to provide personalised recommendations, financial advice, legal advice, or guarantees of future outcomes.

Vehicle ownership and motoring costs are influenced by many factors beyond the scope of any calculator, including but not limited to driving style, annual mileage, geographic location, fuel prices, insurance underwriting criteria, maintenance history, vehicle condition, market fluctuations, regulatory changes, and individual financial circumstances. As a result, all outputs should be viewed as illustrative examples only, not as precise forecasts or definitive statements of cost or suitability.

Users remain fully responsible for how they interpret and use the information produced by these tools. Any decisions made on the basis of the results — including decisions to buy, sell, repair, finance, insure, or replace a vehicle — are taken at the user’s own discretion and risk. ChangeCar.com does not accept responsibility or liability for any financial loss, inconvenience, or other outcome that may arise from reliance on tool outputs or from decisions made using them.

Users are strongly encouraged to treat the results as a starting point for further research. Where appropriate, this may include obtaining quotes from dealerships, garages, insurers, or lenders, checking official government sources, reviewing manufacturer information, and seeking independent professional advice tailored to their specific circumstances before making any commitments.

By using these tools, you acknowledge that ChangeCar.com provides information for general guidance and comparison purposes only, and that final responsibility for decisions, assumptions, and actions rests with you.
