Moving back from Italy to UK

[etst]

Hi there

We lived in London for about ten years before moving back to Italy due to some family issues (I'm Italian and DH is Hungarian). We had a baby in the meantime who is now three years old. We both have a permanent job, my company has a site around Gerrard Cross-Seer Green while my husband can be easily relocate anywhere (he works for Starbucks).
We were thinking to move back to the UK before my kid will start primary school (which is at 6 years old in Italy), do you have any suggestion to where we could move around the Gerrard Cross area which is not far from London as well (let's say around a hour away by train)?? An area with good schools and services??

Thanks in advance
