Comparing car insurance in 2026: 10 checks to get both a good promotional price and the right cover
Comparing car insurance effectively starts with putting offers for the same car side by side on similar conditions, then seeing which plan gives you the price, cover and service that best meet your needs.
If the insurance class, sum insured, repair conditions, excess (deductible) and key cover are the same, the cheaper plan is naturally the better-value offer. But if the details differ, be clear about what is causing the price difference, so you don't end up comparing the wrong plans.
The short answer: to choose good-value car insurance, compare both the promotional price and the key details on the same conditions, then pick the plan that suits your car, how you use it, your budget and the level of risk you want the insurer to take on for you.

A good promotional price should be compared on the same conditions
Two car insurance quotes may be close in price or several thousand THB apart. The difference may come from promotions, a no-claims discount, the sum insured, the repair type, cover limits, the excess (deductible) or driver conditions.
So price is an important point of comparison, and some promotions may genuinely offer the best price. Just make sure first that you are comparing plans of the same class, with similar sums insured, and that the main conditions are not different enough to change your decision.
The simple rule is: compare like with like first, then choose the best-value offer.
10 things to check before choosing car insurance
| What to compare | What to look at | How to use it in your decision |
|---|---|---|
| 1. Insurance class | Class 1, 2+, 3+, 2 or 3 | Choose the class that matches the car's risks and how you actually use it before comparing prices |
| 2. Promotional price and net amount payable | Net premium, discounts, promotions, instalment options and the conditions attached to the price | When the main details are the same, the plan with the lower amount payable has the edge. Check the promotion's expiry date and conditions too. |
| 3. Sum insured on your car | The sum insured and how compensation works if the car is a total loss | Compare similar sums insured, because a different sum insured means a different price and different limits for the car itself. |
| 4. Dealer repair or garage repair | Whether dealer repair or network garage repair is specified, plus the list of repairers that can handle that model | Choose what suits the car's age, parts, where you drive and repairers that are genuinely convenient for you |
| 5. Third-party liability | Limits for death, bodily injury and property, per person and per accident, including the part above compulsory motor insurance (CMI) | Choose limits that suit how the car is used, especially on routes with expensive cars, buildings or public property |
| 6. Excess (deductible) | The agreed Deductible, and any Excess that may apply depending on the type of incident | A plan with an excess (deductible) may get a better price, if the buyer understands it and can accept the amount they will have to pay themselves. |
| 7. Theft, fire, flood and natural disasters | Whether it is included, the limit of cover, and any conditions or endorsements that apply | Choose based on where you park, your routes and the real risks; don't judge by the insurance class name alone |
| 8. Personal accident, medical expenses and bail bond | Limits per person, the number of drivers or passengers covered, and the bail bond limit | Use these to compare extra cover for the people in the car, after checking the main cover |
| 9. Vehicle use and drivers | Private use, for hire, food delivery, passenger transport, business use, or named-driver conditions | Declare your actual use so that the offer and the underwriting conditions are correct |
| 10. Service network and help when something happens | Claims reporting channels, garages or service centres in your area, towing, emergency assistance and coordinators | Helps you judge how convenient things will be after you buy, especially when you need to report an incident, get repairs or ask about a claim |
This table sets out general principles for comparison. Actual cover is governed by the quote, the policy schedule, endorsements, exclusions and the conditions of each insurer.
How to tell whether a “promotional price” is really good value
Before you decide, check these 4 points together:
- Is it the same class of insurance, e.g. Class 1 against Class 1?
- Are the sum insured and the repair type similar?
- Is there any difference in the excess (deductible) or driver conditions?
- Is the quoted amount already the net amount, and does the promotion have any special conditions?
If the key details turn out to be the same or similar, a lower-priced offer is a real strength that you can fully base your decision on. But if the prices differ because the sum insured, repairs or cover differ, choose based on what you actually need rather than comparing a single line of figures.
Which car insurer is best?
The right insurer for you is one that insures your car model and type of use on good terms, has convenient garages or service centres, and offers a competitive price at the time you need cover.
The clearest way to compare is to ask for 2–4 plans for the same car, using the same details and the same start date, then set out the price, sum insured, repair type, excess (deductible), third-party limits and key cover in one table.
If a plan has a standout promotional price and its details meet your needs, you can choose it with confidence. There is no need to pay more for cover you will not use. Just make sure you know what the policy you choose covers, and which risks you still carry yourself.
How to choose for different kinds of car
New cars, high-value cars or cars still on finance
Compare Class 1 insurance, the sum insured, dealer or garage repair conditions, the excess (deductible) and the promotional price together. A plan with the right sum insured, the repair option you want and a good price is a very strong offer.
Older cars that are still used every day
Compare Class 1 with 2+ by looking at the risk of collisions with no other party, flood, theft, fire, the sum insured and your budget. If you choose 2+, make sure you understand the car-to-car collision conditions and the requirement to identify the other party under the policy.
Cars that are rarely used, whose owners can pay for their own repairs
You might consider 3+ or Class 3 to keep within budget, making sure the third-party liability limits are adequate. If there is a good promotional price and the limits are sufficient, it is a good-value choice for this kind of use.
Electric vehicles (EVs)
Check the service centres or garages that can handle that model, the conditions on the battery and high-voltage system, towing, parts and any specific requirements of the policy before comparing prices between insurers.
Cars used for carrying passengers, food delivery or business
You must declare the actual use before asking for a price, because the vehicle code and commercial use affect underwriting and the conditions. Don't compare directly with prices for privately used cars.
7 pieces of information to have ready before checking premiums
- Make, model, sub-model and year of registration
- Registration type and actual use
- Province or area where the car is used, and repairers that are convenient for you
- Expiry date of your current policy and the date you want cover to start
- Your current insurer and insurance class, plus the policy schedule if you have it
- Claims history or damage relevant to underwriting
- Your main priorities, e.g. promotional price, dealer repair, a high sum insured, no excess (deductible) or a limited budget
At the initial comparison stage, don't send your ID card or more detail than necessary through public channels. Send only the information needed to check prices at each step.
How to read a comparison table in 3 minutes
- Choose the insurance class that matches your needs first.
- Make the sum insured and repair type of each plan similar.
- Check the excess (deductible) and the key cover you need.
- Look at the garage or service centre network and the related services in your area.
- Compare the promotional price, net amount payable and instalment options as the deciding step.
When the main conditions are the same, go ahead and choose the plan with the better price. If the details differ, decide whether the extra cover is worth it for how you actually use the car.

Frequently asked questions
Can you compare car insurance on price alone?
Yes, when the key conditions are the same or similar, such as insurance class, sum insured, repair type, excess (deductible) and vehicle use. If the details differ, make them comparable first, then let price decide.
Are cheap car insurance promotions trustworthy?
A promotion with a good price can be a good-value and trustworthy offer. Check the insurer's name, the details in the quote, the promotion's conditions, the payment channels and the policy documents in full. If the cover meets your needs, a lower price is an advantage for you as the buyer.
Can I get a car insurance quote without committing to buy?
Yes. A quote is for comparing before you decide. Give accurate details about the car and how you use it, and check the quote's expiry date, because underwriting conditions and premiums may change.
Is dealer repair always better than garage repair?
Not always. It depends on the car's age and model, the service centres or garages in your area, repair quality, waiting times, parts and your budget. Check the list of repairers you can actually use before choosing.
Why does the same insurer quote different prices?
Prices can vary by sub-model, car year, sum insured, repair type, use, drivers, claims history, excess (deductible), discounts and when the cover starts, so check whether the details in the quotes are the same.
What extra should you check for an EV compared with a regular car?
Check the service centres or garages that can handle that model, the conditions on the battery and high-voltage system, towing, parts and any specific requirements of the policy and the manufacturer.
What is the difference between buying through a broker and buying directly from an insurer?
The insurer underwrites the policy and decides claims, while a non-life insurance broker introduces or arranges the insurance contract. A broker who works with several insurers can help gather, compare and explain offers. Buyers should always check the licence, the payment channels and the documents from the insurer.
