The simplest way to keep on top of your car is to write everything down in one place: MOT and tax dates, insurance renewals, services, repairs, tyres, fuel and mileage. A tidy car maintenance log saves you from missed deadlines, helps you spot problems early and can make your car easier to sell.
Key Takeaways
- In Great Britain most cars need their first MOT three years after registration, then once every year.
- Keep MOT, vehicle tax, insurance and breakdown cover dates together so no renewal slips past.
- Record every service and repair with the date, mileage, garage and cost to build a clear service history.
- Check tyres monthly; the legal minimum tread depth for cars is 1.6mm.
- Logging fuel or charging and mileage shows your true running costs and supports business mileage claims.
Most drivers only think about their car when something goes wrong: a warning light, a letter about tax or a renewal quote that has jumped in price. Owning a car in the UK comes with a steady stream of dates and bills, and it is easy to lose track of them. A simple car maintenance log turns all of that into a calm routine. You know what is due, what you have spent and what the garage did last time.
Why Keep a Car Maintenance Log?
A written log gives you three things. First, peace of mind, because the important dates are written down rather than stored in your memory. Second, better decisions, because you can see whether a car is becoming expensive to run. Third, a stronger position when you sell, because buyers trust a car with a clear history.
It also helps when you talk to a garage. If you can say exactly when the brake pads were last changed and at what mileage, you are far less likely to pay for work that is not needed.
Key Dates Every UK Driver Should Track
MOT
In England, Scotland and Wales, most cars need their first MOT by the third anniversary of registration, and then every year after that. Northern Ireland has its own rules, with the first test at four years. You can have your MOT up to a month (minus a day) before the current certificate runs out and still keep the same renewal date, which gives you time to sort out any repairs.
Driving without a valid MOT can lead to a fine of up to £1,000, and it can affect your insurance. You can check a car's MOT history and due date free on GOV.UK. Write down any advisories the tester gives you too; they are an early warning of jobs that may be needed before next year.
Vehicle Tax
There is no paper tax disc any more, so it is easy to forget when vehicle tax is due. The DVLA sends a reminder, but a note in your log is a useful backup. Tax does not pass to a new owner when a car is sold, so if you buy a car you need to tax it before you drive it. Since April 2025, electric cars also pay vehicle tax, so EV drivers should add this date too.
Insurance and Breakdown Cover
Many policies renew automatically. Logging the renewal date, the provider and last year's price gives you time to compare quotes a few weeks before renewal rather than accepting whatever arrives. Do the same for breakdown cover, which often renews on a different date.
Other Dates Worth Noting
Add your annual service, warranty end date, finance or lease end date and any residents' parking permit. If you have a lease, note the mileage allowance as well, so you can see whether you are on track.
Servicing and Repairs: Build a Proper History
An MOT checks that a car meets minimum safety and environmental standards on the day of the test. It is not the same as a service. Servicing keeps the engine and other parts in good condition, and the right interval depends on your car, so follow the handbook or your garage's advice.
For each service or repair, record:
- The date and mileage
- What was done, including any parts replaced
- The garage or mechanic
- The cost
- When the next job is due, by date or mileage
Keep the invoices in the same folder. When a part fails, you can quickly see whether it is still under a repair warranty. Over time you also build a full service history, which matters to buyers and can help your car's resale value.
Tyres: A Quick Monthly Check
Tyres are the only part of your car that touches the road, so they deserve a regular look. The legal minimum tread depth for cars in the UK is 1.6mm across the central three-quarters of the tyre, around its whole circumference. Driving on illegal tyres can lead to a fine and penalty points for each tyre.
A quick way to check is the 20p test: put a 20p coin into the main grooves. If you can see the outer band of the coin, the tread may be close to the limit and worth checking properly. Note tread depths in your log every month or two, along with the correct pressures from your handbook or the sticker inside the door frame. A tyre log also shows when tyres were fitted, which helps if you need to claim on a tyre warranty.
Monthly Car Checks That Take Ten Minutes
A short monthly routine catches small problems before they become expensive ones. Tick these off once a month:
- Tyre pressures and tread
- Engine oil level
- Coolant level
- Screenwash
- Lights, indicators and brake lights
- Wiper blades
- Any new warning lights, noises or leaks
Before long journeys and as winter arrives, it is worth doing the same checks again.
Fuel, Charging and Mileage
Recording each fill up or charge, with litres or kWh, the price and the miles since last time, shows you your real fuel economy. A sudden drop can be an early sign of under-inflated tyres or a fault that needs attention.
A mileage log matters even more if you use your own car for work. If you are self-employed or your employer does not pay the full rate, you may be able to use HMRC's approved mileage rates for business journeys. Record the date, start and end mileage, the purpose of the journey and whether it was business or personal. Check the current rates and rules on GOV.UK, and keep the log with your tax records. Our guide to side hustle income and tax tracking explains how to keep business records tidy.
Know Your True Running Costs
Most people underestimate what their car costs. Fuel is only part of the picture. A running costs page brings everything together month by month:
- Fuel or charging
- Insurance and breakdown cover
- Vehicle tax
- Servicing, MOT and repairs
- Tyres
- Parking, tolls, congestion and clean air zone charges
- Car washes and accessories
- Finance or lease payments
Add up the year and divide by the miles you drove to find your cost per mile. That number is useful when you decide whether to keep a car, switch to a cheaper one or drive less. It also slots neatly into your household budget; our guide on how to make a monthly budget shows how to plan for irregular bills like insurance and MOTs.
Accidents and Breakdowns: Be Ready
If you are involved in an accident, it is hard to think clearly. A record page in your glovebox folder prompts you to note the date, time and place, the other driver's details, their insurer, any witnesses and the damage, with space for a quick sketch. You must stop after an accident, and you must exchange details where the law requires it. Having the right information to hand makes any insurance claim much smoother.
Moving House or Selling Your Car
If you move house, update the address on your V5C logbook with the DVLA, as well as your driving licence and insurance. Our UK moving house checklist covers this and much more. When you sell, a complete log with MOT history, service stamps and receipts helps you answer buyers' questions and shows the car has been cared for.
Keep Everything in One Place
An app on your phone is easy to forget about, and paper receipts get lost. A printed log in a folder in your home or glovebox is simple and reliable. The UK Car Maintenance Log is a 14 page A4 printable made for UK drivers. It includes vehicle details, key dates and renewals, a service and maintenance log, MOT history, repairs and parts, a tyre log, a fuel and charging log, a mileage log, monthly car checks, running costs by month with cost per mile, and an accident and breakdown record. It works for petrol, diesel, hybrid and electric cars, it is undated, and you can print extra log pages whenever one fills up. You can also use it in GoodNotes or Notability on a tablet.
To plan the money side, pair it with the Monthly Budget Planner Spreadsheet and set aside a little each month for the bigger car bills.

For cars it is 1.6mm across the central three-quarters of the tread, around the whole tyre. Many drivers replace tyres before they reach that limit.
Why should I keep a mileage log?
A mileage log shows your real fuel economy and running costs, and if you use your car for work it gives you the records you need for business mileage claims.
Does a service history help when selling a car?
Yes. A clear record of services, MOTs and repairs reassures buyers and can help you get a better price.
