The St John Ambulance and Rescue Service says islanders should consider joining the Ambulance Subscription Scheme to "prevent that bill shock".
From 2026, Guernsey’s ambulance subscription fee for adults will rise by 4% to £71.
That's the equivalent of £1.37 per week, or just a penny more per day than the 2025 rate.
Chief Ambulance Officer Mark Mapp says the cover is good value for money.
“No one can promise you aren’t going to have an accident or medical incident next year, but what we can tell you is that the cost of calling an ambulance is £585.
"If you’re in Herm and need the Flying Christine, that would be £647 or in Sark, £2,420.
"That’s money most people don’t have readily available and that is added stress after an accident.
"That’s why we have this subscription service, to ensure that if you need an ambulance you don’t have to worry about finding the money.
"It’s just another way we help care for the community – our message really is subscribe and save.
“It’s also entirely possible you won’t have just one accident or medical incident, and many people need us several times.
"Those bills are going to add up and for just £1.37 a week, you can prevent that bill shock."
