Photographic evidence of an existing use: a checklist

Photographic evidence of an existing use proves a state of affairs on one day. It does not prove continuity, and continuity is what a lawful development certificate application under section 191 of the Town and Country Planning Act 1990 turns on. Twenty undated photographs of a flat with a kitchenette will not establish ten years of use as two dwellings. Four dated photographs, each tied to a tenancy agreement and a council tax record for the same year, will go a long way.

The burden sits on the applicant and the standard is the balance of probabilities. National guidance on lawful development certificates makes the useful point that an applicant's own evidence need not be corroborated by independent evidence to be accepted, and that where the authority has nothing to contradict it there is no good reason to refuse. That cuts both ways: thin evidence invites the authority to find its own.

What photographs can and cannot prove

Be precise about the claim each photograph supports, because conflating them is the commonest weakness in a bundle.

Apparent age is where applicants over-reach. Weathered timber and a mossy roof suggest a structure is not new, and no officer will accept that as a date. Treat every photograph as evidence of one fact on one day, and build the chronology from the set rather than from any single image.

Fixing the date and the location

A photograph with no provenance is close to worthless. Three things establish it.

1. The original digital file with its metadata intact, showing camera make and model, date and time, and where the device recorded it, the coordinates. Supply the originals, not copies pasted into a document.
2. An independent anchor visible in the frame. A dated newspaper, a vehicle registration with an age identifier, a shop fascia for a business with known trading dates, scaffolding from a neighbour's consented works, or a seasonal cue such as bare or full canopy that matches the claimed month.
3. A statement from the person who took it, saying when, where and why, and standing behind it.

Metadata is helpful and not conclusive. Camera clocks are set wrongly, files are re-saved by messaging apps which strips the data, and metadata can be edited. An officer who sees nothing but an EXIF date will ask what corroborates it. The independent anchor is what answers that.

Location is easier and often skipped. Key every photograph to a numbered camera position on a site plan with an arrow for the direction of view. A bundle without that plan takes an officer twice as long to read and makes them suspicious of the frames that are hard to place.

Aerial and street-level imagery as corroboration

Aerial imagery is the strongest corroboration available for operational development, because it is independently dated and the applicant did not create it.

Three sources are worth working through. The Environment Agency publishes aerial photography and LIDAR surface data as open data, which can show when a structure appeared and sometimes its height. Commercially available historical satellite and street-level imagery carries capture dates and can often be stepped back year by year. And the local authority's own aerial photography, which many councils hold for several epochs and will sometimes provide on request.

Street-level imagery is particularly good for change of use cases, because it dates fascias, signage, shutters, bin stores and vehicle presence at the frontage. It is also the first thing a planning officer will check, so look at it before you submit and know what it shows. If it contradicts your chronology, deal with that in the statement rather than hoping nobody looks.

LIDAR deserves a mention of its own. Where a building's existence is disputed, a dated surface model showing a structure of the right footprint and height is difficult to argue with, and it is free.

Building a chronology from mixed sources

Put the evidence into a single table, year by year, with a column for each evidence type. Gaps become obvious, and gaps are where applications fail.

For a ten-year continuous use argument, aim for at least two independent items in every year, from different categories. Where one year is thin, say so and explain why, rather than leaving the officer to notice. A short unexplained void in the middle of a chronology reads worse than an acknowledged gap with a reason.

Watch for the break in use. An unauthorised use that ceased for a period and then resumed may not have accrued continuous immunity, and photographs showing an empty, cleared or boarded property in the middle of the period can undo the case. Know what your own photographs show before you put them in.

Metadata, printing and presentation

Submit both forms. A digital folder of original unaltered files, named by reference number, and a printed bundle of contact sheets at a size the officer can actually see.

Each printed image needs a caption block: reference number, date, time if known, photographer, camera position from the site plan, direction of view, and one line on what it is said to prove. Do not crop, rotate or enhance images in the bundle, and if you have done so for clarity, supply the original alongside and say so.

Then add a schedule at the front listing every image with its date and its purpose. Officers work from schedules. A bundle with no index tends to be read once, quickly.

Pairing photographs with documents

Photographs earn their weight when they sit beside paper. The pairings that work hardest:

• A photograph of a fitted kitchen with the tenancy agreement for that unit and the council tax banding for the same period
• A photograph of a commercial yard in use with the business rates record, insurance schedule and supplier invoices
• A photograph of a completed extension with the building control completion certificate and the contractor's final invoice
• A photograph of a shopfront with trading accounts and the premises licence for the same year
• A photograph of occupied bedrooms with the electoral roll entries and utility bills in each occupier's name

Land Registry title entries, Ordnance Survey revision dates, HMRC returns and bank statements showing rent received all do similar work. Our note on assembling document bundles for a different application type, what to submit with a section 73 application, shows the same discipline applied elsewhere.

How officers test a photographic claim

Expect four checks. A site visit to see whether the fabric matches the photographs. A search of the authority's own records, which include council tax, business rates, enforcement files, previous applications and their aerial photography. A look at commercially available street-level imagery for the claimed period. And enquiries of neighbours, which in a disputed case can be decisive in either direction.

Officers also look for internal inconsistency. Foliage that does not match the claimed season, a vehicle with a registration newer than the claimed date, a boiler or meter that was installed later, a satellite dish that appears and disappears. None of that is conclusive on its own, and all of it damages the credibility of the bundle.

Where the authority's record contradicts yours, address it head-on. An application that silently ignores a council tax record showing a single dwelling throughout is a weaker application than one that explains it.

Where a statutory declaration is needed too

Photographs rarely carry a case alone, and a statutory declaration is the standard way to put the applicant's and occupiers' accounts on the record. Declarations are made before a solicitor or commissioner for oaths, and each one should state the declarant's connection to the property, the period they can speak to, and the specific facts they witnessed, rather than a general assertion that the use has continued.

Take this part seriously. Section 194 of the Town and Country Planning Act 1990 makes it an offence to make a false or misleading statement to procure a certificate, and a certificate obtained on a false statement can be revoked. For an immunity argument based on the ten-year period applying to breaches occurring on or after 25 April 2024 under section 115 of the Levelling-up and Regeneration Act 2023, or on the earlier four and ten-year rules for older breaches, the dates in the declarations have to be right.

Have the bundle reviewed by someone who has argued one of these before submission, whether a planning professional of your own or a reviewer from the professional directory. The supporting case normally sits in a Planning Statement, and if you want to see which other documents a proposal may need, browse all 66 report types by category.

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