Born & raised here in Guernsey. Love it, wouldn't live anywhere else. I feel very privileged to live on such a beautiful Island.
Super safe, very low crime rates.
Cost of living pretty high but low rate of tax (flat 20% rate) so you make it work & budget accordingly. House prices are high, just a bit lower than London prices.
Travel is pretty expensive, so this may have an impact if you want to go home to visit family. Also the weather can have a big impact - boat won't sail if it's too rough & planes can't fly when it's foggy!
So many outdoor activities - too many to list! You are never more than 10 minutes from a beach, which are beautiful summer or winter. Fantastic to walk, run or bike around the Island.
Loads of sports clubs that you can sign up to or sign your kids up too. Both indoor & outdoor.
There are some amazing Islands nearby, which are like stepping back in time (ie no cars!). Easy & regular service to visit by boat.
Our Town is just stunning, with high street names & some great little shops selling locally made products.
The local history is fascinating & there are a few locals that do tours.
I would not want to raise my children anywhere else. I can let my 12 year old go off on his bike with his mates & not have to worry too much.
Bad - not much to do if it's raining for kids. The travel cost I mentioned, this can lead to newcomers feeling a little bit like they are stuck on a rock. Lack of shopping choice, so I order online a lot & there are some companies that won't deliver to the Channel Islands which can be a bit of a pain sometimes. Honestly I can't think of too many bad things!
Good - super friendly people. Someone always willing to help. Slower more relaxed way of life. Stunning beaches, stunning scenery. Low rate of tax. Low crime & always a feeling of being safe. Plus a massive bonus right now is that the COVID situation is incredibly well controlled and we have a fantastic team leading the way on that front (although you would have to isolate for 14 days on arrival at the moment).
Hope this helps!
