How to choose a family car on a budget

start with your family's real needs: how many seats, how much boot space for buggies and bags, and how many child seats must fit. Then compare running costs, not just price: motor tax, fuel and insurance add up over years of ownership. Check safety equipment and Euro NCAP ratings, and test your own child seats and buggy in the car before you buy.

Last reviewed: 13 October 2026. Rates, grants and prices change; we recheck this guide after every Budget and at least every six months.

key facts

  • All children under 150 cm or 36 kg must use a child restraint (RSA).
  • Since September 2024, only R129 (i-Size) child seats can be sold in the EU (RSA).
  • Euro NCAP ratings are valid for up to six years from when they are awarded.
  • Motor tax ranges from €120 (electric) to €280 for 151–160 g/km for most family cars.
  • From 1 January 2027, VRT rises by 1% for cars above 80 g/km CO2 (Budget 2027).

matching car type to family

start with your needs

family consider key check
couple, one young child hatchback or small crossover buggy fits in the boot with the parcel shelf in
two children crossover or compact SUV two child seats plus an adult in the back
three children or regular extra passengers large SUV or 7-seater three across, or a usable third row
dog, sports gear or camping estate, SUV or 7-seater with 5 seats in use boot length and a low load lip

things to consider

boot space and child seats

  • compare boot volume with the rear seats up, and check whether it is quoted in litres or VDA dm³.
  • bring your buggy: shape matters as much as volume.
  • count ISOFIX points and test three seats across if you need them; the RSA says there is no one-size-fits-all answer.
  • check rear door opening width and height for lifting children in.

safety ratings

Euro NCAP rates new cars on crash protection and crash-avoidance technology. A rating is valid for up to six years, and the test has become tougher over time, so comparing ratings from different years is only meaningful if the test changed little. Look for automatic emergency braking, lane-keeping assistance and good child-occupant protection.

running costs over the years you'll own it

Over five years, running costs can match the purchase price. Compare:

  • Fuel or charging: every 1 l/100km saved is worth about €280 a year over 15,000 km at September 2026 petrol prices.
  • Motor tax: set by CO2, from €120 for an electric car to €270 for 141–150 g/km.
  • Insurance: get quotes on the exact version.
  • Finance: compare the total amount payable 

A family test-drive checklist

  1. bring the children, their seats and your buggy, and fit everything yourself
  2. lLoad the boot as you would on a Saturday: buggy, shopping, sports bag.
  3. sit behind your own driving position to check rear legroom.
  4. check visibility over the shoulder and how easy the car is to park.
  5. try the infotainment, phone connection and rear USB sockets the children will use.
  6. drive on roads you use every day, including a motorway stretch if you commute.

new or nearly new?

A nearly new car avoids the steepest early depreciation, but a new car brings a full warranty and the latest safety equipment, and finance offers can narrow the gap. Whichever you choose, check history and warranty carefully
