A garage conversion in Bexley, Bexleyheath or Old Bexley starts from £645 for drawings. The council grants most householder applications: 95% of 877 decisions in the latest four quarters.

One borough, one set of rules for Bexley and Bexleyheath
People search for a garage conversion in Bexley and in Bexleyheath as if they were different places. For planning they are one: the London Borough of Bexley decides both. Your own road may carry restrictions the borough-wide picture hides, so the first check is always the council's records for your address.
Section 55(2)(a) of the Town and Country Planning Act 1990 excludes from development works that affect only the interior of a building, or that do not materially affect its external appearance. Bricking up the garage door and adding a window changes the outside. Our guide to planning permission for a garage conversion takes you through that decision.
How Bexley treats householder applications
Our analysis of MHCLG planning application statistics, table PS2 (released 24 Sep 2026, quarters to 2026 Q2) shows Bexley decided 877 householder applications, including prior approvals, between 2025 Q3 and 2026 Q2, and 95% were granted.
Excluding prior approvals, the share of householder decisions made within 8 weeks rounds to 100% for those four quarters, by the same analysis, so very few took longer. Borough-wide numbers like these describe a department's habits, and they carry no promise for your application.
Our analysis of the Planning Inspectorate Casework Database (released 1 Oct 2026, Casework Database 2609) counts 157 householder appeals in Bexley decided between 2021 and 2026, with 34% allowed.
Certificate, application or neither
If you want the council's written view before you build, a certificate of lawful development for a proposed householder project costs £274, half of the full fee. A householder planning application costs £548 (SI 2012/2920 as indexed from 1 April 2026; the £274 is our arithmetic).
Our lawful development certificate drawings service prepares the plans a certificate needs, and the garage conversion drawings service covers the conversion itself.
