How to Write a Good Permission Letter for Metal Detecting in the UK

Getting permission to metal detect on private land is one of the most important skills any detectorist can develop. The quality of your written request can mean the difference between access to a productive field and a flat refusal. Landowners receive all manner of requests, and a poorly constructed letter will almost certainly end up in the bin. A well-crafted, professional permission letter, on the other hand, demonstrates respect, knowledge of the law, and trustworthiness — three things every farmer and landowner needs to see before they hand over access to their land.

This guide walks through every element of a strong permission letter, covering the legal framework that underpins detecting in England, Wales, and Scotland, the etiquette landowners expect, and the specific wording that tends to work. Whether you are writing to a local farmer in Norfolk, a National Trust tenant in Wiltshire, or a private estate owner in Yorkshire, the principles here apply across the board.

Understanding the Legal Framework Before You Write

Before putting a single word on paper, you must understand the law. Writing a permission letter without grasping the legal context will undermine your credibility instantly, and landowners with any experience of detectorists will notice gaps in your knowledge immediately.

The Treasure Act 1996

The Treasure Act 1996 is the primary piece of legislation governing finds in England, Wales, and Northern Ireland. It replaced the ancient common law concept of Treasure Trove and created a statutory definition of what constitutes “Treasure.” Under the Act, Treasure includes:

Any object (other than a coin) that is at least 300 years old and contains at least 10% precious metal by weight
Any group of two or more prehistoric base-metal objects found together
Any coin from a find of two or more coins, where the coins are at least 300 years old and at least 10% precious metal
Any object, whatever its composition, found in association with Treasure

Critically, Treasure legally belongs to the Crown, not the finder or the landowner. However, the British Museum and regional museums administer a reward system. Under the Treasure Act Code of Practice, any reward is typically split 50/50 between the finder and the landowner — unless a prior written agreement specifies a different arrangement. This is precisely why your permission letter needs to address the reward split clearly.

The Treasure Act 1996 (Designation) Order 2002 extended the definition further, and there has been ongoing consultation about expanding the Act’s scope to cover certain non-precious-metal finds of significant historical importance. Always check the current guidance on the Portable Antiquities Scheme (PAS) website, operated by the British Museum, for the most up-to-date definitions.

The Portable Antiquities Scheme

The Portable Antiquities Scheme was established in 1997 and went fully national in 2003. Run by the British Museum in partnership with Amgueddfa Cymru (the National Museum Wales), the PAS encourages the voluntary recording of archaeological finds made by members of the public, including metal detectorists. As of 2023, the PAS database contains well over 1.6 million recorded finds, making it one of the most significant archaeological datasets in the world.

Mentioning the PAS in your permission letter shows the landowner that you take your responsibilities seriously and that finds made on their land will be recorded properly. This is a strong signal of trustworthiness.

Scotland’s Different Legal Position

It is worth noting that Scotland operates under different legislation. The Treasure Act 1996 does not apply in Scotland. Instead, the Civic Government (Scotland) Act 1982 and the principle of bona vacantia (ownerless property reverting to the Crown) apply. In Scotland, all finds of treasure belong to the Crown and are administered by the Crown Office and the Procurator Fiscal Service. The national museum in Edinburgh, National Museums Scotland, handles the reporting process. If you are detecting in Scotland, your permission letter should acknowledge this distinct legal framework.

Who to Address and How to Find the Right Person

One of the most common mistakes new detectorists make is addressing their letter to the wrong person. Sending a generic letter to “The Farmer” or “The Landowner” immediately signals that you have not done your research.

Identifying the Landowner

Land ownership in England and Wales is registered with HM Land Registry. For a fee of £3 per title register, you can search the Land Registry online to find the registered owner of any parcel of land. This is well worth doing before writing your letter, as it allows you to address the correspondence by name.

Bear in mind that the registered owner may not be the person who farms the land. Many agricultural holdings are tenanted. If a farmer is a tenant, the freeholder (landlord) also has rights over what happens on the land. In practice, you will generally need permission from both the tenant farmer and the freeholder if the farm is rented. Tenant agreements vary; some explicitly prohibit tenants from granting third-party access for activities such as metal detecting without the landlord’s consent.

Local knowledge is also invaluable. Speak to people in the village, attend local National Council for Metal Detecting (NCMD) club meetings, or contact your regional Federation of Independent Detectorists (FID) group to find out who owns or farms specific land in your area.

Estate and Institutional Landowners

Large institutional landowners, such as the Church of England, the Forestry Commission, Natural England, the National Trust, and the Ministry of Defence, have formal policies on metal detecting. Generally speaking, the National Trust does not grant metal detecting permissions on its own land, though it may do so in exceptional circumstances for research purposes in consultation with an archaeologist. The Church of England similarly maintains strict controls. For estate land managed by a land agent, address your letter to the agent by name and title, not the landowner directly.

The Structure of an Effective Permission Letter

Your letter should follow a clear, professional structure. Handwritten letters can work well in rural settings where a personal touch is valued, but a typed, well-presented letter on quality paper almost always makes a better first impression. Keep it to one page if at all possible.

Your Name and Address

Place your full name, address, and contact details at the top right of the letter in the traditional British format. Include a mobile number and an email address. Landowners who want to respond quickly will appreciate having multiple contact options.

The Date

Always date your letter. This is not merely a formality — it establishes a clear record of when the request was made, which can be relevant if a permission agreement is later drawn up.

The Landowner’s Name and Address

Place the landowner’s full name and address on the left-hand side, below the date. Use their correct title (Mr, Mrs, Ms, Dr, or the appropriate courtesy title if writing to a peer). Getting this right shows you have taken the time to find out who you are writing to.

A Clear Subject Line

A brief subject line beneath the salutation makes it immediately clear what the letter is about. For example: Re: Request for Permission to Metal Detect at [Farm Name / Field Name]. This helps the landowner file it correctly and makes it easier for them to locate if they want to refer back to it.

Writing the Body of the Letter

Paragraph One: Who You Are

Introduce yourself clearly and honestly. State your name, where you live, how long you have been metal detecting, and whether you are a member of any recognised detecting club or national organisation. Membership of the National Council for Metal Detecting (NCMD) or the Federation of Independent Detectorists (FID) carries weight because these bodies have published Codes of Conduct that members are expected to follow. The NCMD’s Code of Conduct, for instance, aligns closely with the advice produced jointly by the NCMD, FID, and English Heritage (now Historic England) in the document A Practical Guide to Metal Detecting.

If you have any professional background relevant to history, archaeology, or countryside management, mention it. If you are a member of a local history or archaeological society, say so. Any affiliation that signals you are a responsible, engaged member of the heritage community strengthens your case.

Paragraph Two: What You Are Asking For

Be specific about what you want. Vague requests are easy to refuse. State clearly:

Which fields or areas of land you wish to detect on (if known)
How often you would like access (occasional visits, monthly, seasonal)
Whether you intend to detect alone or with a small group
The proposed time of year — for example, after harvest and before autumn drilling, which is the most common and least disruptive window for arable farmland

If you are not certain which fields are suitable, offer to walk the land with the landowner first to identify the best areas. This approach shows respect for their knowledge of their own land and creates an opportunity for a face-to-face conversation that often proves more persuasive than the letter alone.

Paragraph Three: How You Will Conduct Yourself

This is arguably the most important paragraph. Landowners’ primary concerns are damage to crops, interference with livestock, disruption to drainage systems, and the threat of trespassing by others once they have granted one person access. Address these concerns head-on.

Commit specifically to the following, in writing:

Moving Forward

Once you have the fundamentals in place, the possibilities open up considerably. The UK offers fantastic opportunities for anyone interested in this hobby, and with the right foundation you will be well placed to make the most of them.
