TL;DR: Adding a named driver can reduce your car insurance premium, but it can also make it more expensive. Uswitch data based on comprehensive car insurance quotes from October to December 2025 found that the average premium fell from £591.35 for a main driver-only policy to £379.76 when a spouse was added – a difference of £211.59. However, adding an unspecified named driver increased the average premium to £709.23. The effect depends on the drivers, vehicle and insurer. Always provide accurate information about who uses the car most, as falsely declaring the main driver can be considered insurance fraud or misrepresentation.
Adding a named driver to your car insurance policy can sometimes reduce the cost of your cover. However, it is not a guaranteed way to get cheaper car insurance.
The effect of adding another driver depends on factors such as their age, driving history, claims history and relationship to the main driver, as well as the vehicle and insurer.
This means adding an experienced driver with a clean driving record could reduce your premium in some cases, while adding a younger or higher-risk driver could make it more expensive.
If you're looking for ways to reduce your car insurance costs, it's worth getting quotes both with and without an additional driver rather than assuming the price will go down.
How Much Can Adding a Named Driver Save?
Uswitch data based on comprehensive car insurance quotes from October to December 2025 shows that adding a spouse was associated with a significantly lower average premium.
The figures were:
| Drivers on the policy | Average premium |
|---|---|
| Main driver only | £591.35 |
| Main driver + spouse | £379.76 |
| Main driver + 1 named driver | £709.23 |
| Main driver + 2 named drivers | £918.22 |
Based on these averages, adding a spouse was associated with a £211.59 lower average premium than a main-driver-only policy.
That's a reduction of around 36%.
However, these are average figures rather than a guaranteed saving. Your own car insurance quote could be higher or lower depending on your circumstances.
The figures also show why you shouldn't assume that adding any named driver will make your insurance cheaper. The average premium for a main driver plus one unspecified named driver was actually higher than the main-driver-only figure.
Why Can Adding a Named Driver Make Car Insurance Cheaper?
Insurance companies assess the risk associated with the people who will drive the vehicle.
When you add another driver, the insurer can take information about that person into account when calculating the premium. This can include factors such as their:
- Age
- Driving experience
- Claims history
- Driving convictions
- Licence details
- Occupation
- Relationship to the main driver
An experienced driver with a lower-risk profile may sometimes have a positive effect on the quote.
However, there is no automatic discount for adding an experienced driver. Another driver can increase the premium if the insurer considers them to represent additional risk.
This is why it is important to compare the price before and after adding someone to your policy.
What Is a Named Driver?
A named driver is someone who is insured to drive your car under your car insurance policy but is not the main driver.
The main driver should be the person who uses the vehicle most frequently.
A named driver can use the car as part of the policy, but they should not be incorrectly described as an occasional driver if they are actually the person who uses the car most.
The exact cover available to a named driver depends on the terms of the insurance policy.
Adding someone to your policy also doesn't normally mean that they automatically build their own No Claims Bonus. Some insurers may offer their own named-driver discounts or schemes, so check the individual insurer's terms if this is important to you.
Can Adding Your Spouse Reduce Your Car Insurance?
It can.
The Uswitch data above found a substantial difference between the average premium for a main driver-only policy and one where a spouse was added.
However, the fact that someone is your spouse does not automatically mean your insurance will be cheaper.
Your insurer will consider the circumstances of both drivers and its own pricing criteria. Adding a spouse with a different driving history, age or claims record could have a different effect from adding someone else.
The only way to know whether adding your partner or spouse will reduce your premium is to get a quote.
Can Adding a Parent Reduce Car Insurance for a Young Driver?
Adding an experienced parent to a young driver's policy may reduce the premium, but it isn't guaranteed.
The important point is that the young driver must still be declared as the main driver if they are the person who uses the car most.
Trying to put the policy in a parent's name simply to obtain a cheaper premium when the younger driver is actually the main user is known as fronting.
What Is Fronting on Car Insurance?
Fronting is when someone gives an insurer inaccurate information about who the main driver of a vehicle is, usually to obtain a cheaper premium.
A common example would be a parent declaring themselves as the main driver when their child is actually the person who uses the car most.
This can have serious consequences. If an insurer discovers that the information provided about the main driver was inaccurate, it may take action against the policy and could refuse a claim or avoid the policy depending on the circumstances.
The Financial Ombudsman Service has published cases involving fronting where insurers took action after discovering that the person declared as the main driver was not actually the vehicle's main user.
The safest approach is simple: always tell your insurer who actually drives the car most.
Does a Named Driver Get the Same Insurance Cover?
A named driver is covered to drive the vehicle under the terms of the policy, but the precise level of cover and any conditions depend on the policy you have.
For example, if you have comprehensive car insurance, a named driver may be able to drive the vehicle with comprehensive cover, subject to the policy terms.
Check your insurance documents if you're unsure what cover applies to additional drivers.
Can a Named Driver Affect Your No Claims Bonus?
An accident involving a named driver can potentially affect the main policy and its No Claims Bonus, depending on the circumstances and the insurer's terms.
Named drivers do not normally build their own No Claims Bonus on someone else's policy in the same way that a main policyholder can.
Some insurers have offered named-driver discounts or schemes that recognise a driver's claims-free experience when they later take out their own policy. However, these arrangements vary between insurers and shouldn't be assumed to be available everywhere.
What Happens If the Named Driver Has Points or Claims?
Adding someone with penalty points, previous claims or limited driving experience can affect your insurance premium.
However, there is no universal rule that a driver with points or a claim will always increase the price. Insurers use their own pricing models and consider multiple factors.
That's why you should provide accurate information about every driver you add to your policy.
Don't leave out convictions, claims or other relevant information simply because you think it will make your insurance cheaper. Providing inaccurate information could cause problems if you need to make a claim.
Does Adding a Named Driver Increase Your Mileage?
Adding another driver doesn't automatically mean you need to increase your annual mileage.
Your mileage estimate should reflect how much the vehicle is genuinely expected to be driven during the policy period.
If adding another driver means the car will be used more frequently and your expected annual mileage increases, tell your insurer. Mileage can form part of the information used to calculate your premium.
It's better to provide an accurate estimate than deliberately underestimate your mileage to try to reduce the cost of your insurance.
How to Check If Adding a Named Driver Will Save Money
If you're considering adding a partner, spouse or experienced driver to your car insurance, there are a few simple steps you can take.
1. Get a quote without the additional driver
Find out how much your policy would cost with the current main driver and your existing details.
2. Add the additional driver
Enter their details accurately, including their age, driving history and claims information.
3. Compare the prices
Check whether the premium has gone up or down.
Don't assume that an experienced driver will automatically make your insurance cheaper.
4. Check the policy details
If the price falls, make sure the policy still provides the cover you need and that all the information you've provided is accurate.
5. Compare insurers
Different insurers assess risk differently, so a named driver who reduces the price with one insurer may have little effect – or increase the price – with another.
Can Adding a Named Driver Make Car Insurance More Expensive?
Yes.
Adding another driver doesn't automatically result in a discount.
Uswitch's data illustrates this clearly. While the average premium for a main driver plus a spouse was lower than the main-driver-only average, the average premium for a main driver plus one unspecified named driver was £709.23.
That's £117.88 more than the £591.35 average for a main driver alone.
This is why the effect of adding a named driver is individual to the policy rather than a universal car insurance saving.
Choosing a Car That Could Be Cheaper to Insure
If you're a new or young driver, the car you choose can also have a significant effect on your insurance quote.
Rather than focusing on a particular make or model being "cheap to insure", compare quotes for the exact vehicle you're considering. Factors such as the engine, specification, age of the vehicle, your location and your driving history can all affect the price.
Adding an experienced named driver can be another factor worth testing when comparing quotes, but it should never replace accurately declaring who the main driver is.
So, Does Adding a Named Driver Reduce Car Insurance?
Sometimes, yes – but not always.
Current Uswitch data shows that adding a spouse was associated with a £211.59 lower average premium compared with a main-driver-only policy. However, adding an unspecified named driver was associated with a higher average premium.
The key takeaway is that there is no guaranteed named-driver discount.
If you have a partner, spouse or experienced driver who genuinely uses your car, it may be worth getting a quote with them added to your policy. Just make sure the main driver is declared accurately and all information about the drivers is correct.
If adding another driver increases your premium, you can compare other insurers to see whether you can find a more competitive quote.
Never make someone a named driver simply to reduce the price if they are actually the main user of the car. This could amount to fronting and create serious problems if you need to make a claim.
Once you've checked how adding a named driver could affect your premium, it's worth comparing your options to see what cover is available at a competitive price. Compare car insurance with Regit to explore your options and find cover that suits your needs.
