Charges for planning history searches and document copies

The planning history search cost on a typical purchase should be nothing. Inspecting the statutory planning register is free, and under the Environmental Information Regulations 2004 a council cannot charge you for access to a public register or for examining information at its offices. Charges start when you ask for copies, when the file sits in an archive that has to be retrieved, or when the search turns into a request that takes staff time.

For anyone buying a house to convert or an HMO, this is the cheapest due diligence available and the most often skipped.

Why a planning history matters at purchase

The history tells you what the lawful use is, which is a different question from what the property is being used as. A six-bedroom house let to six sharers may be a lawful Class C4 house in multiple occupation, an unlawful change from C3, or a C3 dwelling in an area with an Article 4 direction that removed the permitted change.

It also tells you what conditions bind the property. Occupancy restrictions, a condition removing permitted development rights, a personal permission, an agricultural tie, a restriction on the number of bedrooms, a parking space that cannot be built on, or a planning obligation registered as a local land charge.

And it tells you about enforcement. Immunity rules changed: the old four year periods for operational development and for change of use to a single dwelling were extended to ten years by section 115 of the Levelling-up and Regeneration Act 2023, which came into force in England on 25 April 2024 and applies to breaches occurring after that date. Older breaches are still judged under the previous periods. That single distinction can decide whether an unauthorised conversion is safe to buy.

Where the position remains unclear, the only formal answer is a certificate of lawfulness under section 191 or 192 of the Town and Country Planning Act 1990. The fee for one is set by the national fee regulations and is indexed, so check the current schedule rather than a figure in an old note. The economics of that decision sit alongside the wider cost of retrospective development.

What is free on the public register

Section 69 of the 1990 Act requires every local planning authority to keep a register of applications, and the procedure order sets out what it must contain. The register has to be available for public inspection at all reasonable hours, and inspection is free.

Most authorities publish it online, with scanned application forms, drawings, officer reports, decision notices and consultation responses. The depth of scanning varies. A council that digitised from 2000 onwards will show you a full file for a 2012 extension and a single index line for a 1978 garage.

Three free sources sit alongside it and are often overlooked. Committee reports and minutes, which explain why a decision went the way it did. Appeal decisions, held by the Planning Inspectorate and searchable by site. And the authority's Article 4 direction register and local plan policies map, which tell you whether permitted development rights have been withdrawn in that street.

Archived files, microfiche and retrieval charges

Older files are the ones that cost money. Depending on the authority, pre-1990 records sit on microfiche, in a basement store, at an offsite document warehouse or with the county record office.

Retrieval is a service rather than register access, so a charge is legitimate. Councils that offer it publish a rate, usually per file or per half hour of staff time, and some require an appointment with a set notice period. Two practical points: ask for the file reference from the register index before requesting retrieval, because a request for everything at an address costs more and returns duplicates. And ask whether the file can be scanned to email, which is often cheaper than an appointment and always cheaper than travelling.

Where records were transferred at local government reorganisation, the successor authority may hold nothing before the transfer date. County record offices hold some pre-1974 planning material, and their charges are separate.

Copy charges and the limits that apply

A council may charge a reasonable amount for making environmental information available, and planning records are almost always environmental information. Two limits matter.

First, the regulations prevent a charge for access to a public register or for examining information at the authority's premises. So reading the file on site is free even where copying it is not.

Second, the charge has to be reasonable and the authority has to publish a schedule of charges. A fee that recovers the cost of photocopying and postage is reasonable. A fee calculated to deter requests is not, and pointing at the published schedule usually resolves a disputed invoice.

Where a request falls under the Freedom of Information Act instead, a different limit applies: the authority can refuse where compliance would exceed the appropriate limit, which for a local authority is £450 calculated at £25 per hour of staff time, equivalent to 18 hours of work. Under the environmental information route there is no equivalent monetary cap, though a manifestly unreasonable request can be refused.

Information requests where records are missing

Sometimes the file has gone. Fire, flood, a reorganisation, a disposal schedule that predates anyone still employed.

The sequence that works:

1. Ask the authority in writing for confirmation that no record is held, and keep the reply. A written statement that the council holds no record of an enforcement notice is itself useful evidence.
2. Check the local land charges register, which records planning obligations, enforcement notices, tree preservation orders and conditions restricting use, and which is maintained under the Local Land Charges Act 1975.
3. Check Land Registry title documents for restrictive covenants and for planning agreements referred to in the charges register.
4. Ask the vendor for their own copies, including any building control completion certificate.
5. Where a use has to be proved rather than a permission found, assemble statutory declarations, tenancy agreements, council tax records, utility bills and dated photographs. That bundle supports a certificate of lawfulness application.

Do not assume the absence of a permission means a breach. It may mean the works were permitted development at the time, and the rules in force then are the rules that apply.

Building control records as a parallel source

Building control is a separate function with a separate archive. It holds full plans applications, building notices, inspection records, completion certificates and regularisation certificates.

For a conversion this is often more informative than the planning file. A 1998 completion certificate for a loft conversion tells you the works were signed off. Its absence tells you to price remedial opening up. Councils generally charge for a building control history search or for copies, and the charge is a discretionary service fee rather than a register access fee, so it is properly payable.

Where the work was signed off by an approved inspector rather than the council, the council may hold only the initial notice and the final certificate. Ask for both.

A search order that avoids duplicate charges

Work outwards from what is free.

1. The online planning register at the address, plus the two or three neighbouring addresses, because plot histories cross boundaries.
2. The policies map, Article 4 register and conservation area boundary.
3. Appeal decisions for the site.
4. The local land charges register through the conveyancing search rather than as a separate request.
5. Only then the archived planning file, with a specific reference.
6. Building control records, last, and only where the physical works matter.

Budget a modest sum for retrieval and copies rather than nothing, and treat anything above that as a signal to instruct a planning consultant instead. On a purchase where the lawful use is the whole basis of the valuation, a professional review costs less than a void. The same principle applies to other early spend on a scheme, as with utility connection costs in a development budget, and it is worth knowing which fees are recoverable if an application later stalls, as set out in planning fee refunds for non-determination.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
