How to buy a car in the UK

How to buy a car

It can be tricky to know where to start when you set out to buy a car.

Here are the steps you'll usually need to take:

Step 1: Set your budget and research total cost of ownership (TCO). Calculate total costs, not just the purchase price. This will include car insurance, fuel, tax, and maintenance. For more money-saving ideas, read our top tips for cutting the cost of car insurance.

Step 2: Choose your model and fuel type (petrol, diesel, hybrid, electric). Think about what type of car will best suit your lifestyle needs. You may need a bigger car to accommodate family, or something fuel-efficient for frequent journeys.

Step 3: Decide between paying cash or financing (PCP, HP, personal loan). Get pre-approved for a loan to strengthen negotiating power.

Step 4: Research where to buy a new car. This might be from a dealership, an online broker, or a private seller.

Step 5: Test drive and negotiate the deal. Don't be afraid to walk away if the price or condition isn't right, and be vigilant for any potential scams - if the price seems too good to be true, it probably is.

Step 6: Final checks, paperwork, and arranging insurance. Tax the vehicle and ensure it's insured before driving it away.

How do you buy a car privately?

Buying from a private seller can be cheaper than going through a dealer, but you need to be cautious.

• Check the seller and the car: Make sure the V5C logbook matches the address, and ask about outstanding finance. Always view the car in daylight
• Inspect and test drive: Look for paintwork issues, tyre wear, leaks, and check the MOT history. Bring a knowledgeable friend or mechanic if needed
• Agree the price and pay securely: Negotiate based on the car’s condition. Use a secure payment method, get a signed receipt, and make sure the seller completes the V5C transfer
• Before you drive: Tax the vehicle using the GOV.UK service and ensure you have insurance. Even if the seller is responsible for notifying the DVLA, you must receive the V5C

Buying privately can be cheaper because you avoid dealership fees. But it also comes with more risk, so it’s important to stay alert.

Keep these key tips in mind:

• If a deal seems too good to be true, it probably is
• Never buy a car without seeing the V5C logbook
• If you’re unsure what to look for, take a knowledgeable friend or mechanic with you

Should I buy a used or new car?

Choosing a new or used car depends on your budget, needs, and personal preference.

Here’s a breakdown of the pros and cons for each option:

Buying a used car

Pros:

• Cheaper purchase price: You can get a higher-spec car for less than a new one
• Lower insurance and registration costs: Premiums, registration, and taxes are generally cheaper
• Immediate availability: No factory wait times - you can take the car home right away
• Reduced depreciation: The first owner has already absorbed the biggest drop in value

Cons:

• Unknown history: The car may have hidden damage, poor service records, or tampered (‘clocked’) mileage
• Higher maintenance and repairs: Unexpected repairs may be needed soon after purchase
• No or limited warranty: Manufacturer coverage may have expired
• Less advanced technology: Safety, infotainment, and fuel efficiency may lag behind new models
• Higher financing rates: Loans on used cars often carry higher interest rates than new cars

Buying a new car

Pros:

• Warranties: Manufacturer coverage protects against unexpected repairs
• No hidden history: You’re the first owner, so there’s no risk of past damage
• Financing benefits: Dealers and manufacturers often offer low-interest deals
• Customisation: You can choose colour, trim, and features
• Up-to-date technology: Modern safety, infotainment, and fuel efficiency

Cons:

• Fast depreciation: New cars lose 20–30% of their value in the first year
• Higher purchase price: New vehicles are more expensive upfront
• Higher insurance and taxes: Premiums and registration fees are generally higher
• Limited stock customisation: Buying off the lot may limit your options

A nearly new or ‘approved used’ car could be a good middle ground if you’re unsure. You avoid the steepest initial drop in value while still paying less than you would for a brand new car.

These vehicles often have low mileage and some manufacturer warranty remaining, which can give you extra peace of mind at a more affordable price.

What is the best time of year to buy a new car?

In the UK, the best discounts are often available at the end of each sales quarter - March, June, September, and December. Sales teams are usually under pressure to hit targets during these periods, which can result in better incentives and more room to negotiate.

End-of-life car models often come with the best deals. Manufacturers and dealers reduce prices to clear inventory and make room for newer models. This is when you’re most likely to see offers like 0% APR, cashback, or reduced financing rates.

March and September are also important because of the bi-annual plate changes. New registration plates signal a newer car, which can influence resale value. Timing your purchase around these changes can help you get the best deal.

What documents do you need when you buy a car?

When buying a car, you must have the following documents:

• V5C Logbook: This must be in the seller’s name and you must fill out the relevant sections to change ownership with the DVLA
• MOT Certificate: This is for cars over three years old. You can check the history online
• Insurance: You must have valid car insurance before the vehicle is driven on public roads

Ending a lease and buying the car

Buying a car at the end of a Personal Contract Purchase (PCP) or lease agreement involves paying the final balloon payment, often known as the Guaranteed Minimum Future Value (GMFV), to the finance company.

This payment is set at the start and allows you to buy the car outright, often with a small 'option-to-purchase-fee.' You have the option to refinance this amount or take out a bank loan if you don't have the money upfront.

If the car's actual market value is higher than the GMFV, you may be able to part-exchange it, using the positive equity as a deposit for a new car, or buy it and sell it privately for a profit.

How to test drive a new car

Test driving a new car is a great way to get a feel for how the vehicle runs and allow you to test out being behind the wheel. But before you take it on a test drive, make sure to complete the following checks:

• Check insurance is covered: You'll need to check you're insured to take the car for the test drive
• Research common faults: Check if the car has any reported common faults. Look at reviews, online boards, and other testimonies from drivers of the car
• Book ahead: Arrange an appointment to guarantee the specific model of car you want is available

During the test drive, make sure to check the following:

• Brakes: Check the braking efficiency
• Handling: Check the responsiveness of the steering
• Visibility: Adjust seats and mirrors
• Infotainment usability: Check all systems are working correctly
• Comfort: Think about who will be travelling in the car. You may want to ensure there's room for a baby or child seat, for example. Check for fit, comfort, and space

When inspecting the exterior of a new car, look for:

• Panel gaps
• Paintwork condition
• Rust
• Uneven tyre wear

It's a good idea to drive the car on different road types, like slow roads and faster roads like dual carriageways. This helps you to get a better feel of the driving experience.

Think about how the car will fit into your daily life and commute, considering your own personal routine. You'll want the drive to feel comfortable and able to handle your typical travel routes.

How to negotiate the best price for your new car

When buying a new car, the list price is not final, and negotiation is expected. It's worth negotiating the total cost, not just the monthly finance payment.

Instead of a cash discount, you can negotiate on:

• Free servicing packages
• Accessory upgrades
• A higher valuation for your part-exchange

To secure the deal, make sure you get everything in writing, and walk away from the sale if you begin to feel pressured.

Should I take out a car finance loan?

Taking out a car finance loan can be a good option if you can’t afford to buy a car outright and can comfortably manage the repayments. Keep in mind, though, that finance usually costs more overall because of interest.

A Personal Contract Purchase (PCP) lets you pay smaller amounts upfront, but can be more expensive than a personal loan. PCP contracts often come with mileage limits and penalties for damage.

With Hire Purchase (HP), you own the car after the final payment. With PCP, you can either make a final ‘balloon payment’ to keep the car or return it at the end of the contract.

Because the car acts as security, lenders are often willing to offer larger loans, sometimes at better rates than a standard personal loan. Finance is also more accessible for those with poor credit, while personal loans usually offer better rates for people with good credit.

Always calculate whether you can realistically afford the repayments. Missing payments could result in your car being repossessed.

How to insure a new car

When you buy a new car, your insurance needs will depend on whether you’re replacing, keeping, or adding a vehicle.

If you already own a car

You’ll need to decide whether you want to transfer your current policy over to your new car or whether you will be better off cancelling your current policy and taking out a new one to cover your new vehicle.

If you plan to keep your old car as well as your new car

Whatever you do, you must inform your insurer when you buy a new car, even if your new car will be a second (or third, fourth or fifth) vehicle.

You will need to tell your insurer, as they need to know how many vehicles are kept in the household.

If you’re replacing your current car

Get in touch with your insurer and ask if it is willing to insure the new one.

Bear in mind that it may charge you to change your vehicle details, and the car you've bought could affect the price, particularly if it's more valuable or powerful than your current vehicle.
