How to buy a new or used car online with confidence

Buying a new or used car online in the UK is safe, flexible and often quicker than visiting a showroom as long as you understand who you’re buying from, how you’re paying, and what rights protect you.

From fully digital retailers to traditional dealers offering click-and-collect, online car buying now covers everything from browsing to finance approval and home delivery. You can get pre-approval car finance, compare prices transparently and even arrange independent inspections without leaving your sofa.

That said, confidence comes from clarity. Knowing who the legal seller is, checking the car’s history, understanding your consumer rights and sorting your budget upfront all make the process smoother and far less stressful.

In our guide, we’ll walk you through whether buying online is right for you, how the step-by-step process works, where to buy, and what checks will give you the proper peace of mind before you commit.

Key takeaways

• Online car buying is safe as long as you can verify the legal seller and use a reputable platform or dealership (like our trusted dealerships).

• Many sellers offer a hybrid buying process that combines online purchase with in-person test drives or collection.

• Getting finance pre-approval sets a clear budget and speeds up the online purchase process.

• Vehicle history checks, MOT records and independent inspections provide reassurance when you can’t inspect the car in person.

• UK consumer protection laws apply, with strong rights when a car is purchased online, particularly with home delivery.

Should you buy a car online?

Working out whether buying a car online is right for you means weighing up the pros and cons. It often comes down to personal preference.

Buying online could be the best choice if:

• You have a fixed budget and want price transparency.

• You know exactly what car you want.

• You want a quick, easy transaction without the showroom experience (and aren’t a fan of haggling with the dealer)

Buying at the showroom could be the best choice if:

• You want to check out a potential purchase in person or want a conventional test-drive.
• You want in-person guidance, or you’re comfortable negotiating face-to-face.

Many dealerships now offer click-and-collect or even home test drives. This gives you the best of both worlds, online ease with a tactile check before that final yes.

Step-by-step: how to buy a car online

1. Get pre-approved: Find out how much you can borrow for car finance and see what car finance options might work for you. Having your finances sorted helps you work out exactly what you can afford.

2. Search and shortlist: Use online filters to narrow down your needs. Don't just look at the price. You should also check the total cost of ownership, including insurance groups and fuel economy.

3. Background checks: Research the car’s MOT history and run a car history check before you commit.

4. Lock in the price: Get a full on-the-road (OTR) price breakdown, including any admin fees.

5. Payment: Using car finance can provide additional protection under consumer credit law if something goes wrong with the vehicle. In some cases, the lender may share responsibility with the seller, meaning you can raise a complaint with them as well. Depending on the circumstances, this can help when seeking a repair, replacement or refund.

6. Delivery & handover: Choose what suits you, but remember that home delivery often triggers extra "distance selling" protection.
   Post-handover inspection: Check the car and paperwork thoroughly the moment it arrives.

Where to buy your car online

There are four main platforms to buy a car online:

• Marketplaces

• Online retailers

• Franchised & independent dealers

• Manufacturers

Franchised and independent dealers are the classic type of car dealership, and many now offer the option to buy online rather than at the showroom. They may sell all types of cars, or just those made by a single brand (or a limited number of brands). To find thousands of trusted dealerships, you can head to the Carmoola app.

Is it safe to buy a car online?

Buying a car online is safe as long as you make sure the seller is reputable. Look out for these trust signals: 

• Verified customer reviews across Trustpilot, Google and specialist automotive forums

• Membership of trade bodies like the National Motor Dealers Association (NMDA) or Society of Motor Manufacturers and Traders (SMMT)

• Identifiable Companies House registration and trading history

• AA, RAC-approved or one of Carmoola’s Trusted Dealerships, since these must meet certain quality standards and follow ethical business practices

• If a dealership offers finance, it must be approved by the FCA (Financial Conduct Authority)

What are my consumer rights when buying a car online?

If you’re buying through an online car dealership, the good news is that you’re covered by various consumer rights. Here’s a summary of the three main ones:

Consumer Rights Act 2015 

This covers you for both new and used cars. It means your vehicle must be roadworthy, meet reasonable standards for its age and mileage, and match what was advertised. If it isn’t, you can reject it within 30 days for a full refund. Between 30 days and six months, the dealer gets one opportunity to fix any problems. If they can't, you could be entitled to a full or partial refund. 

Consumer Contracts Regulations 2013 

Also known as ‘distance selling regulations’, this applies if you buy a car entirely online without seeing it or completing any of the paperwork in person. It gives you a 14-day ‘cooling-off period’ to cancel the order without reason, plus another 14 days to return the car. Mileage limits may apply, and you would be required to repay any interest accrued.

Section 75 of the Consumer Credit Act 

This applies if you use a credit card for any part of your purchase (however small) of a car that costs between £100 and £30,000. It makes your card provider equally responsible if the car is faulty or not as described, giving you an extra layer of protection.

Budgeting and car finance options

One of the benefits of buying a car online is that it can make paying for it less stressful. You get to plan your budget and study finance options from the comfort of your home. 

As with an in-person purchase, you have a few different ways to pay when buying a car online. The main ones are:

• Cash

• HP car finance

• PCP car finance

• Credit card

• Personal loan

Buying with cash speaks for itself, although you’re more likely to use a bank transfer with this method than actually handing over a big wad of banknotes. 

HP car finance and PCP car finance each allow you to spread the cost over a fixed period once you’ve paid a deposit. With an HP agreement, you own the car once you’ve made all your monthly payments (and usually a small option-to-purchase fee). A PCP agreement differs because your monthly payments don’t cover the entire cost of the car. At the end of the agreement, you can either return the car to the lender, make a final ‘balloon payment’ to own it, or put any equity towards a new PCP deal for your next car. 

If you apply for car finance, it will involve credit checks and affordability checks to make sure you can afford to make your payments. Both types of finance are covered by the Consumer Credit Act 1974, meaning that there’s an initial 14-day ‘cooling off’ period where you have the right to cancel the agreement without facing a penalty. 

Our in-depth guides to HP vs PCP car finance and cash vs car finance have more details to help you decide what might be right for you. 

It’s also possible to buy a car with a credit card if you have a high enough credit limit, although not all dealers accept this form of payment, and others may charge for it.

A bank loan (also known as a personal loan) could make sense depending on your circumstances and the price of the car, but you need to do your sums carefully and look at the total cost payable when comparing with other forms of lending. 

If you're looking for a better deal on an existing agreement, find out if car refinancing might be an option. 

Must-do vehicle checks

If you’re buying a car online, here are some of the checks to do:

• Vehicle history check (HPI check): This reveals if the car has outstanding finance, has been written off (Cat N or S), or stolen. With Carmoola, customers can run free car history checks. 

• MOT history: Use the free government checker. If you see a history of "advisories" for the same issue year after year, it’s a sign the previous owner may have skimped on maintenance.

• Video requests: Ask for a "cold-start" video. Hearing how the engine sounds first thing in the morning can reveal more than a dozen polished photos.

Test drives, inspections and buying confidence

Most sellers will offer for you to visit a showroom or depot to take a test drive. Some might even arrange an at-home test drive. 

However, test-driving a car before buying it online means you don't benefit from the 14-day return window provided under Consumer Contracts Regulations 2013. If you buy entirely online, you could use these 14 days to try out the car and return it if you choose to, but there’s likely to be a mileage limit, so it's worth reading the small print carefully. 

Another option is to book an independent inspection of the car you’re interested in using a third-party firm. This involves a qualified engineer giving the car a thorough examination and usually taking it for a test drive. Think of it as a full medical for the car you’re interested in. 

Pricing and negotiating online

Paying the right price is just as achievable online as it is in person.

• Research: Use valuation tools to see what a dealer would pay (trade-in) versus what you should pay (retail).

• Part-exchange: Trading in your old car online is straightforward. Use valuation tools (like Carmoola’s track my car’s value) to get an estimate.

• Hidden fees: Make sure to check for any additional fees, some dealers could add admin fees or delivery charges that can bump the price up by hundreds.

• Negotiating: You can still haggle with the dealer. Use email or chat to provide links to comparable, cheaper listings. If you're buying near the end of a month or quarter, dealers are often more motivated to hit their targets.

Delivery, handover and paperwork

Once you have a date finalised, it’s time for the boring-but-important bits.

• Insurance & Tax: You must have insurance in place before delivery. Road tax can be sorted online in two minutes during the handover.

• The V5C: Ensure the "New Keeper" part of the logbook is completed.

• Visual checks: When the car arrives, check it against the listing photos immediately. If there’s a scratch that wasn’t in the pictures, note it on the delivery note before the driver leaves.
