Moved from Marlow to Ascot - your help needed with connectivity decisions

A housekeeping note and a request for suggestions, folks.

We’ve now moved house from beautiful Marlow to equally lovely Ascot. Home of the world famous race course (300 years old this year I think).

I have a greenfield house to play with so I would welcome your connectivity suggestions.

There’s nothing installed at the moment and I’ve got a bit of time before I need to actually get something active.

There’s probably a BT connection in the house.

The area supports BT Infinity. (There’s no Virgin Media fibre broadband in the area.)

So my question to you is:

What would you do for connectivity?

I’ve had excellent experience with Be Unlimited. I was thinking about using them again.

I’m drawn to BT Infinity — the BT.com site reckons I’ll get 34mb down and 8mb up. But I don’t really fancy being lumped in with the consumers so I was considering buying the BT Infinity Business option that includes some kind of prioritisation.

Orrrr there’s always a leased line. Perhaps that’s stupid. How much do these things cost nowadays?

What do you suggest?
