Rear and side extension drawings in Bexley

What Bexley decided on householder applications
Bexley made 877 householder decisions in the four quarters to 2026 Q2 and granted 95% of them (our analysis of MHCLG planning application statistics, table PS2). The count includes prior approvals, so it describes the council's general stance on home alterations, not the odds for one plot.
Speed is the other half of the record. Of the householder decisions that were not prior approvals, 100% were decided within 8 weeks in the same four quarters (our analysis of the same table). A complete, correctly drawn application leaves the case officer little to query.
Rear extension or side extension: what gets drawn
Whether you search for a side extension, a room extension or a rear one, the council wants the same evidence: existing and proposed plans, elevations and sections, plus a block plan showing the neighbours. A side extension changes the street frontage as well, so its elevations need most care. Our rear extension drawings page lists the full set, and the house extension drawings page for Bexley covers extensions that combine a side and a rear addition.
The published price list starts single-storey rear extension drawings (survey and planning or permitted development drawings) at £695. See the pricing page for how that sits beside our other fixed fees.
Bexley has had 157 householder appeals decided since 2021, and 34% were allowed (our analysis of the Planning Inspectorate Casework Database).
The 3 metre and 6 metre rear limits
Under permitted development, a single-storey rear extension to a house other than a detached one may extend beyond the original rear wall by up to 3 metres. Under the larger home extension prior approval route, the limit rises to 6 metres for the same kind of house (General Permitted Development Order, Schedule 2 Part 1). Our permitted development glossary entry explains what the original house means.
Bexley determined 40 larger home extension prior approvals in the eight quarters to 2026 Q2 and granted 45% (our analysis of MHCLG planning application statistics, table PS1). Those are the cases Bexley granted or refused; notifications where it found prior approval was not required are recorded separately and sit outside the 45%. A neighbour can object under that route, so a 6 metre scheme needs drawings that show the neighbour's windows honestly. The larger home extension guide sets out the steps.
Appeals and the register of conservation areas
Bexley has had 157 householder appeals decided since 2021, and 34% were allowed (our analysis of the Planning Inspectorate Casework Database). That is a record of past cases, not a forecast.
The national register holds 31 live conservation-area entries for Bexley (our analysis of the MHCLG Planning Data Platform conservation-area dataset). Check Bexley Council's conservation area map for your address before you design, because the conservation area glossary entry shows what that changes.
The council fee against ours
From 1 April 2026 the fee for a householder application to enlarge, improve or alter a single dwellinghouse is £548. That is paid to the council with the application, separately from our drawing fee.
