Recent planning decisions in Oxfordshire

Updated 10 October 2026

In the 12 months to 10 October 2026, The local planning authorities decided 43 householder home-improvement applications near Didcot, Abingdon in Oxfordshire in the cached public records — 41 approved.

Coverage: Sampled 2 km town-centre catchments: Didcot, Abingdon; not a county-wide total. Extensions, loft conversions, dormers, garage conversions and porches only. Records without clear householder classification, location or final decision are excluded. Proposal summaries describe the home-improvement element; see the council record for the full proposal.

These are public council decisions about other people’s applications. They are not Hampshire Build projects and do not predict the outcome of your project.
