Householder application or full application for a dwelling

Use a householder application for works to a house and the land around it. Use a full application for anything that creates a new dwelling, alters a flat, or changes the use of land. Choosing wrongly does not usually produce a refusal. It produces an invalid application, a returned fee, and four to six weeks lost while you resubmit, which on a build programme with a contractor booked is worse than a refusal you could have appealed.

The distinction is not in the Town and Country Planning Act. It comes from the fee regulations and the way the application forms and procedures are organised, and the practical consequences run through fees, publicity, documents and appeal rights.

What counts as householder development

Householder development is development within the curtilage of a dwellinghouse, for purposes incidental to the enjoyment of that dwellinghouse, or alterations and extensions to it. Rear and side extensions, loft conversions with dormers, porches, garages, garden rooms, outbuildings, hardstanding, walls, fences, gates and satellite dishes all fall in.

Two conditions sit behind that. The building has to be a dwellinghouse, and the works must not create an additional dwelling or change the use.

A house divided into flats is not a dwellinghouse for these purposes, so an extension to a ground floor flat is a full application even though the work looks identical to the neighbour's extension next door. Listed building consent, where required, is a separate application in either case.

Flats, annexes and the cases that catch people

Annexes are the recurring argument. Where the accommodation is properly incidental and ancillary to the main house, sharing its curtilage and used by the household or their dependants, it sits within householder development. Where it has its own kitchen, its own entrance, its own garden and is capable of independent occupation, the council will treat it as a new dwelling and expect a full application, with everything that follows: its own infrastructure levy liability, its own affordable housing position on larger sites, and often a different parking standard.

Officers look at the physical arrangement rather than the label on the drawing. A studio described as ancillary but designed as a self-contained flat with a separate access will be assessed as a flat.

The other recurring case is garden land. Enclosing part of a field into a domestic garden is a material change of use, so it is a full application, and it is one that frequently attracts objection in the countryside or the Green Belt. Our note on the difference between a lawful development certificate and planning permission covers what to do where you believe no permission is needed at all.

Fees, publicity and consultation

Planning fees in England were uplifted in December 2023 and are subject to annual indexation, so take the current figure from the fee schedule on gov.uk rather than from an older article or an agent's out of date sheet. The fee for an invalid application is refunded, but the time is not.

Appeal routes, which differ more than people expect

This is the difference that matters most and is noticed least. An appeal against refusal of a householder application uses an expedited written representations procedure with a 12 week deadline for lodging the appeal, and the parties do not exchange further statements in the way a full appeal allows. Comments made to the council at application stage are passed to the inspector, and new representations are not invited.

A refusal of a full application carries the ordinary six month appeal deadline and a choice of procedure, with written representations, a hearing or an inquiry depending on the issues.

So a householder appeal is faster and costs less, and gives you far less room to develop the case. If a scheme is finely balanced, the quality of the original submission carries more weight than it would on a full application, because there is no second bite.

Documents each one needs

A householder application is short: forms, the ownership certificate, a location plan at a recognised scale with the site outlined in red, a block plan, existing and proposed floor plans and elevations at consistent scale, and the fee. Add a Heritage Statement where the house is listed or in a conservation area, and a Design and Access Statement where the designation and floorspace thresholds in the procedure order are met.

A full application for a new dwelling adds more: a planning statement addressing policy, drainage and surface water details, ecology where habitat or a building capable of supporting roosting bats is affected, contamination where the site history warrants it, arboricultural information where trees are affected, and a biodiversity gain plan position. A Planning Statement is optional in name and useful in practice, because it is the document that answers the officer's report before it is written.

Check the council's local validation list either way. Local lists add requirements beyond the national ones, and they are the reason most applications are returned.

Which documents the officer will actually read

On a householder application the case officer reads the elevations and the block plan, and then looks at the relationship to the neighbours. Overlooking, overshadowing and the 45 degree line from neighbouring habitable room windows decide most of these decisions, so draw the neighbouring windows on the elevations rather than leaving them off. A short heritage or design note is worth writing even where it is not required, because it gives the officer text to lift into the report.

On a full application for a dwelling the officer is testing the principle first: is the site in a location where a new home is acceptable under the adopted plan, and does it meet the policy tests for infill, backland or countryside development. A submission that leads with design and leaves the principle to an appendix is answering the second question before the first.

Getting it wrong, and how to check first

The usual failure sequence is an agent submitting an annexe as householder development, the validating officer disagreeing, the application being returned, and the applicant resubmitting as a full application six weeks later with a different fee and a further 21 day consultation. Nothing about the scheme changed.

Three checks avoid it. Ask whether the building is a dwellinghouse rather than a flat. Ask whether anything in the proposal could function as a separate dwelling. Ask whether any land is changing use. If the answer to the second or third is yes, or even arguable, submit as a full application, because there is no penalty for using the wider route and there is a real penalty for using the narrower one.

Where the position is still uncertain, the duty planner service or a short pre-application enquiry will resolve it in a sentence, and the prior approval or planning permission comparison deals with the third route that sometimes applies instead.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. A lawful development certificate is the only formal way to confirm that works are lawful.
