Quick Tips
Jump-start your understanding with these essential tips
Enter what you actually pay now for car insurance. This makes the comparison and recommendation much more relevant to your situation.
Your exact insurance group number (based on your car model), driving history, no-claims bonus, and your postcode all significantly affect what you pay. These results show typical ranges, not your exact quote.
If you enter your registration, we use real DVLA data (fuel type, engine size, CO₂, vehicle age) to make the estimate more personal.
A comprehensive policy (covers damage you cause and your own damage) makes sense for higher-value cars. For older, lower-value cars, third-party only is often enough.
If you have multiple drivers or multiple vehicles, this tool shows typical savings. Shop around with insurers to compare actual quotes.
Step-by-Step Guide
Follow these steps to get the most from this tool
Start with your real postcode and what you actually pay each month for car insurance now. If you don't know your monthly cost, divide your annual bill by 12. This makes the comparison more accurate for your situation.
💡 Pro Tips:
- •Use your actual current premium, not an estimate.
- •Include breakdown cover, excess protect, or add-ons if they're already in your premium.
Check the three options: keep your current setup, switch to a group policy (2+ drivers), or use a multi-car discount (2+ vehicles). If you use DVLA lookup, we adjust the estimate using your vehicle age, engine size, and CO₂. These are still planning estimates, not final insurer quotes.
💡 Pro Tips:
- •Check the "Data Sources" section to understand what's real data, estimated, or calculated.
- •Visit insurer websites to get real quotes before switching.
If you're thinking about buying a new car, use the vehicle value calculator to see what coverage type makes sense. A newer, pricier car usually needs comprehensive coverage. An older, lower-value car often works fine with third-party only.
💡 Pro Tips:
- •Enter your car's make, model, year, mileage, and condition for an estimate.
- •Professional car valuations are more accurate for high-value vehicles.

Deep dives for advanced users
Every car model has an insurance group (1–50). Higher groups usually cost more to insure because repairs cost more, performance is higher, or theft risk is higher. Use True Cost of Owning Your Car to include insurance in long-term car decisions.
A no-claims bonus is a discount you earn for each year you drive without making a claim. Most insurers offer 5–9% discount per year, up to 60% maximum after about 10 years. This isn't included in these estimates—when you get a real quote, insurers will ask and apply your bonus.
A group policy covers 2+ named drivers under a single policy. You save 10–20% typically. The catch: if anyone on the policy makes a claim, it counts against everyone's no-claims bonus. Compare this against each driver having their own policy before switching.
If you have 2+ vehicles at the same address insured with the same company, ask for a multi-car discount (typically 15–25% off). This is straightforward—most insurers offer it if you ask when buying the second policy.
Comprehensive coverage (you and damage you cause are both covered) makes financial sense until your car's value drops below £5,000–£7,000. Below that, the premium savings from third-party only outweigh the risk. Use our vehicle calculator to get a recommendation based on your specific vehicle.
These estimates combine real data (your postcode, your vehicle inputs) with benchmarks (typical regional premiums and discounts). Your actual savings will differ based on your personal driving history, claims record, and the specific insurers you compare. Treat results as a planning guide, then verify with real quotes.
