The following byelections are known about. Now incorporating corrections!
Higham Ferrers Lancaster (East Northamptonshire District Council), caused by the death of Barry Sauntson, a Conservative.

She will serve until 2011.

A former Leader of the Council, Jackson had been sitting as an Independent although he was elected as a Conservative; he was disqualified for failing to attend a meeting of the council or its committees for six months.
