Sundon has a village hall and a pub, the Red Lion.

[2] The parish church, dedicated to St Mary, is a Grade I listed building.

[3] The Victorian vicarage is Grade II listed, and features very fine latticed windows.

[4] Because of changes to its boundary, the parish no longer includes Sundon Park (which is now an area of Luton) or the "Sundon Substation" of the National Grid for electricity (which lies west of the railway, near the village of Chalton).
