Your kids are the perfect age to move in regards to education.
I would check out the exam results for the grammar schools in the area you are looking at as some are very high, even not taking all pupils with the 1st banding (I'm thinking sullivan upper)
There is a seag support group on fb which has all grammar schools lowest marks in this year's papers ranked. Just something to maybe look up and be aware of.
Also look into the provisions of local high schools, it seems from talking to friends that those who go to a traditional high school are doing OK, but the newer academies are like the wild west.
But the education standards here are nothing like we read about on threads on MN.
Even if your job isn't available here, I'm sure you have transferable skills.
It is amazing being so close to the sea, then nature within minutes from home, I'm on the other side of the lough. Belfast is 10 mins away, the North Coast less than an hour.
Buying a house if obviously less expensive, I think our utilities rates are lower. Insurance is more expensive. Belfast has just been named recently as the most expensive weekend away in Europe.
The NHS is a disaster, waiting lists are unfathomable, if you can get private health care but our few private clinics have waiting lists now, a few years ago you could phone and been seen that week. Now their waiting lists are months.
Politics are shite, always will be, they get nothing done and prefer to fight with each other than spend public money for good.
And the weather can be a bit crap
In spite of all that, I love NI. The people, the communities, the craic, the traybakes. Comeon home!
