Check the battery connections to ensure they are clean and tight, as loose or corroded connections can cause electrical issues. If the connections are fine, consider having the battery tested to ensure it's holding a proper charge, as a weak battery can trigger multiple warning lights. Let me know how it goes or if you have any further questions!
I have already done both of your suggestions terminals are clean and tight and the battery has been tested by the RAC and it is holding it's charge properly

Inspect the alternator to ensure it's charging the battery correctly. A faulty alternator can cause electrical malfunctions and trigger warning lights. Check the alternator belt for wear and tension as well. If the alternator seems fine, it might be worth checking the vehicle's ground connections for any corrosion or looseness. Let me know if you need further assistance or if you have any questions!
