The telecoms watchdog Arcep has set up a map where you can check this, at tinyurl.com/yg45fh4g.
It allows you to zoom in to see if connection to “superfast” fibre-optic broadband is possible yet.
A colour scheme shows generally how many properties are connectable in your area, but at the large scale you can even see your building.
There are alternative ways of viewing the map, which you can choose by clicking in the bottom right.
