Farm record keeping: what to keep and for how long

Keep anything that touches money for six years. Keep spray and pesticide application records for at least three years — and in practice longer, because assurance schemes tend to expect it. Keep assurance records for whatever the current version of your standard says. Keep field history forever; it's the one record that gets more valuable with age.

That's the retention answer, and it's the easy half of the job. The hard half is being able to put your hand on a record when HMRC, an assessor or a merchant's query actually asks for it. A record you can't find within ten minutes is, for practical purposes, a record you don't have.

How long to keep what

Record type	Keep for	Notes
Financial and VAT	6 years	HMRC's requirement. Invoices, self-billed invoices, contracts, anything tied to a sale
Spray and pesticide applications	3 years minimum	The statutory floor. Assurance often expects longer, so treat 3 as a minimum, not a target
Assurance scheme records	Per the current standard	Requirements move between versions — check the standard you're actually audited against
Staff, payroll, health and safety	Varies	Payroll sits inside the financial 6 years; some health and safety records need longer — check current guidance
Grain movement records	6 years, safe default	Weighbridge tickets, grain passports and collection notes all touch transactions, so file them with the money
Field history	Indefinitely	Cropping, yields, inputs, drainage, problem patches. Never worth throwing away

Two habits make the table workable. First, when in doubt, keep it — storage is cheap and shredding is permanent. Second, don't try to remember the rules load by load; set the retention once per drawer or folder and let the filing do the thinking.

Scattered records are missing records

Here's the test. It's February, and the merchant's self-billed invoice for 600 tonnes of feed wheat — call it £108,000 at £180 a tonne — is 14 tonnes short of what you think left the farm. Fourteen tonnes is roughly £2,500. To argue it, you need the weighbridge tickets for every load on that contract, the collection notes, and ideally the haulier's references.

If the tickets are in the kiosk, the collection notes are in a lever-arch file in the office, three loads were texted to your phone by whoever was carting, and one week of harvest lives in a notebook that might be in the Discovery — you don't have records. You have an archaeology project. Most people give up and take the merchant's number.

The one-place principle fixes this: every record of a given type lives in exactly one place, and everyone on the farm knows where. One ticket book (or one app). One spray records system. One file for contracts. The place matters less than the fact there's only one of it.

Paper or digital, honestly

Paper survives power cuts, flat batteries and software companies going bust. Digital survives everything else — fire, rain, diesel, mice, the ticket book leaving in someone's overalls, and the office move where a box quietly disappears.

On balance digital wins, for three practical reasons. It's searchable: find every load of Skyfall in seconds rather than an afternoon. It's backed up, provided you set it up that way — a spreadsheet that exists only on one laptop is paper with extra steps. And it adds itself up.

But the deciding factor is usually entry, not storage. A paper diary that gets filled in beats an app that doesn't. If the digital system is slower than the job it's recording, it loses to the back of a fag packet every time. A reasonable halfway house for plenty of farms: paper capture where paper is genuinely faster, photographed or typed into the one digital place on a set day each month.

The records that pay, and the ones that just avoid trouble

Compliance records — spray records, waste transfer notes, the assurance paperwork — mostly exist to avoid a penalty. Do them properly, file them once, think about them as little as possible.

The records that actually pay are the operational ones. Field history tells you which fields consistently earn their keep and which are passengers. Weighbridge tickets turn into field yields and settle merchant disputes. Drying records tell you what a wet harvest actually cost per tonne. These are the numbers that change decisions — variety choice, rotation, whether that awkward 6 ha block is worth farming at all — and they only exist if someone recorded them at the time.

The good news is the overlap: the same harvest records that build your yield picture cover a decent chunk of what a Red Tractor audit wants under traceability. Records done once, used twice.

The hour-a-month routine

Filing collapses when it becomes a yearly mountain. An hour a month keeps it flat:

1. Empty the pockets — tickets, notes, receipts, photos on the phone — into the one place for each record type.
2. Chase the gaps while memory is fresh: the load with no field name, the spray record still waiting on the agronomist's recommendation sheet.
3. File what's complete, and once a year (not more often) purge what's past retention. Financial paper from seven years ago can go; field history stays.

Pick a fixed day — last Friday of the month works — and treat it like a service interval. It's dull. It's also the difference between an audit that takes a morning and one that takes a fortnight of scrambling.

Frequently Asked Questions

How long do farm records need to be kept in the UK?

Six years for anything financial or VAT-related, at least three years for spray and pesticide application records (longer in practice for assurance), and whatever the current standard says for assurance scheme records. When a record touches a sale — weighbridge tickets, passports, contracts — treat it as financial and keep it six years.

Are digital farm records acceptable for audits and HMRC?

Generally yes — assessors and HMRC are used to digital records, and legible, dated, backed-up digital records are usually easier to present than paper. Check the current version of your assurance standard for anything it wants in a particular form, and make sure digital records are genuinely backed up rather than living on one laptop.

What's the minimum retention for spray records?

Three years is the statutory minimum for pesticide application records, but treat it as a floor. Assurance schemes often expect longer, and the records cost nothing to keep — most farms simply hold them with the rest of the field records indefinitely.

Which records are worth keeping beyond the legal minimum?

Field history — cropping, yields, inputs and problems by field — is worth keeping forever, because it drives variety, rotation and rent decisions years later. Harvest and weighbridge records are worth keeping well past six years too: they're the raw material for yield benchmarking, and they weigh nothing.
