I’ve lived in (east) Suffolk all my life.
Those saying the transport non existent and schools awful, it obviously depends where you are, it’s not as remote and cut off in Norfolk and Suffolk as some here are saying.
As far as Norfolk goes, I would happily live on the outskirts of Norwich. There’s plenty for dc (teens) to do imo, though it is easier once they’re old enough to drive.
I lived very near the east coast Suffolk/Norfolk border for a long time, near the heritage coast (AONB). Much prettier than Norfolk or Cambridgeshire (IMO 😀), but definitely sleepier, state school choices not so good in that area. Good community spirit though and there are e.g., market towns with nice selections of shops and better sports facilities.
I now live further south in the county, still east, a bit north of Ipswich, which is a much better location in terms of getting to places and things to do . We are very rural but can be in Ipswich in 20 minutes with all the facilities and leisure there. There is a bus service, not great but there is some provision, though I would say driving is an essential.
Dd goes to one of the two outstanding secondary schools nearby. It takes an hour and 10 mins into Liverpool St from Ipswich or by road, 20 mins to get on to the A12, e.g., to London or just over an hour to Norwich which is fine now and again for shopping.
Ipswich is nicer than people think and handy to have fairly nearby, I absolutely wouldn’t live there but really like where we are. It’s beautiful, I’m within easy reach of the coast, nice towns within 15-35 mins for shopping, beautiful walks, low crime, good house prices. We live in a ‘nice’ area 😊 and got a lot for our money property wise.
It’s not vibrant, it’s a different way of life and doesn’t appeal to all, (though it appeals a lot to London second home owners.)
One dc is still at school, the others are young adults at Uni or working they have absolutely loved growing up here and haven’t been keen to leave.
