Finding a seven seater that still has usable boot space with all seats up is one of the trickiest challenges in family car buying. Fold the third row down and most cars look spacious, but the real test is what fits with everyone on board. Here are the best 7 seater cars with big boot space in the UK for 2026.
Best 7 Seater SUVs for Boot Space
Kia Sorento
The Kia Sorento remains one of the most practical seven seaters on sale, with a genuinely usable boot even in seven seat mode and self levelling rear suspension that helps maintain ride height when fully loaded.
BMW X7
The BMW X7 offers some of the largest boot figures in its class, with 750 litres available with the rear seats up, expanding to a huge 2,120 litres with all seats folded flat, making it one of the most versatile large SUVs on the market.
Mercedes-Benz GLS
Even in full seven seat configuration, the GLS offers 470 litres of boot space, rising to 890 litres with the third row folded, and an enormous 2,400 litres with every seat down, ideal for families who occasionally need maximum cargo capacity.
Skoda Kodiaq
The Skoda Kodiaq is known for practicality at a lower price point than premium rivals, with a boot that stays genuinely useful even with the third row in use, plus clever underfloor storage compartments.
7 Seater Boot Space Comparison
| Model | Boot Space (7 Seats Up) | Boot Space (All Seats Folded) |
|---|---|---|
| BMW X7 | 326 litres | 2,120 litres |
| Mercedes GLS | 470 litres | 2,400 litres |
| Kia Sorento | 187 litres | 1,996 litres |
| Skoda Kodiaq | 270 litres | 2,035 litres |
What to Check Beyond the Headline Litre Figure
- Boot space with all seats in use: this is the figure that matters most if you regularly carry seven people plus luggage.
- Third row folding mechanism: some cars require seats to be removed entirely for maximum space, which is less convenient than a simple fold flat design.
- Load lip height: a lower lip makes loading heavy items significantly easier, particularly for pushchairs or shopping.
