Check the guarantee certificate, it just may have more than 12 months terms.
Charge it until it indicates it’s fully charged and take it to a battery specialist who has the equipment to load test it. You may get this test free.
If you need to replace it remember that the old one has a scrap value of 10-20 quid depending on size.

When I start the van it's 14;2 . When the engine is not running it's only when I switch some things on it drops to 7 quickly then back up to 12 once I switch them off
It appears to not be taking any load, the voltage you read with the engine running is the input voltage.
It can read 12v but not have any load capacity, it needs load testing.
How do I check a load test
It’s either just horribly empty and desperately needs charging properly, or it’s actually knackered.
An outside possibility is that there’s an issue with your wiring and whatever you’re switching on is drawing way more current than you think and causing huge voltage sag. However, given you’re reporting it getting all the way down to 7v, I think it’s pretty likely the battery is not healthy. As others have said, get it properly tested (after charging fully).

Charges from the main engine system battery.its only a year old no it's never been fully discharged as it's under the drivers seat
