Paperwork: what to keep and for how long

You open that drawer – the one you'd rather not look at – and it's a jumble: bank statements, prescriptions, repair invoices, a degree certificate wedged between two rent receipts. Every year you promise to sort it, and every year you close the drawer with a sigh. Let's be honest: nobody really knows what to keep.

And that's understandable. There's no single legal retention period for every piece of paper. Each document has its own timescale, based on how long you might need to challenge, claim or prove something. So let's go through it together.

Health: the core records to keep for life

Start with your health, because this is the exception to the shoebox. Your personal health record, vaccination history, medical certificates and blood group card: keep these indefinitely. So should letters and results linked to a chronic or serious condition, and anything relating to a workplace illness or accident – medical certificates, test results, expert reports. They are your history, and when a health professional needs to understand your background, they make the picture much clearer.

In a different category, prescriptions, receipts and private health insurance claim records are worth keeping for around two years. That's long enough to check a payment or query an incomplete reimbursement. If your insurer has its own rules, follow those. After that, you can file them elsewhere. And if you're unsure about an old medical document, ask a health professional rather than trying to judge it alone.

Your National Insurance record deserves a regular check, too. It's free to view your State Pension forecast on GOV.UK, and it's a sensible habit – especially if you've had periods of unemployment, illness or time abroad. That record never gets thrown away: it's the official memory of your working life.

With health paperwork, people often say it's safest to keep everything. Old scans, test results from twenty years ago, letters shoved into a random folder: you don't need to keep it all. But keep a clear thread. An orderly file with a simple chronology is far more useful than a chaotic pile where nobody – including you – can find anything.

Money, banking and insurance

Now for the least romantic but most crowded category. Insurance policies don't all last forever: how long you keep them depends on the type of policy and its terms. For most UK contracts, the limitation period for bringing a claim is six years in England, Wales and Northern Ireland, and five in Scotland – but insurance policies can set their own time limits, so check the paperwork or ask your insurer. A life insurance or investment policy should be kept well beyond that, often until it matures or is claimed. Who wants to lose track of what they've invested?

On the banking side, bank statements and paying-in slips are worth keeping for around six years. That's usually long enough to query a disputed payment or prove a transaction. The same goes for records of stocks and shares, and for written acknowledgements of debt – six years is a sensible rule of thumb. Don't mislay those.

For tax, a useful marker: keep tax returns and notices for at least 22 months after the end of the tax year they relate to. If you're self-employed or have more complex affairs, keep them for at least five years. Records that support a tax relief or allowance should be kept for as long as the relevant rules require – check with your insurer, accountant or HMRC before throwing anything away. Another easy-to-forget category: significant expenses that could matter later – repair invoices for an appliance still under guarantee, building work certificates, notes relating to a dispute. You don't think about them at the time, and that's exactly when you regret it. If in doubt, scan the document and check how long to keep it before you shred it. It costs nothing.

A few more markers: water bills – keep for at least two years, and longer if you need them for a tax claim or dispute. Insurance premium receipts, letters about a claim and child benefit paperwork: around two years. Council tax bills and bailiff fees: two years. Penalty charge notices: two years.

Family and work

Here we enter the 'keep indefinitely' category – the documents to store somewhere safe and dry. Birth, marriage and civil partnership certificates, divorce or dissolution papers, wills, adoption records, diplomas and qualifications: keep them for life in a dedicated folder. There's nothing more frustrating than producing a crumpled birth certificate at the worst possible moment.

Another file not to lose sight of: workplace accidents and periods of unemployment. Certificates, letters and records relating to them should be kept long-term, because they can affect your pension and your rights. For your National Insurance record, the rule is clear: keep payslips and employment contracts until you reach State Pension age. It sounds like a lot, but they prove what you contributed, especially if a period is missing from your record. Child benefit paperwork, by contrast, only needs around two years.

Housing and car

This is the vaguest category – and the one where people make the most mistakes. It all depends on why the expense happened. A major repair to your home, such as water damage or a new roof? Think in terms of ten years or more for structural guarantees, and keep the paperwork about any defects. A simple maintenance bill, on the other hand, can be kept for much less time.

For a car, the rhythm is different: warranties and limitation periods are often shorter, and again you should check the contract to see what to keep and for how long. Useful habit: the service history stays with the car and matters at resale – it isn't a document to throw out during a clear-out.

For rented housing, keep rent receipts for around six years after you move out – they can be evidence if there's a dispute with a former landlord. Do the same with tenancy agreements and solicitor's fees. Emails and letters with the managing agent or freeholder stay useful while the file is active; there's no fixed period, because it depends on when you might need them. For service charges, the limitation period is generally six years.

A word on the small things people think are pointless: a chimney sweep certificate – keep it for at least a year. It pleases no one, but it can be useful if there's a fire or insurance claim. And you need to be able to find it.

Budget

For supplies, prices vary by range and where you shop – stationery shops, supermarkets, office suppliers, online. Expect a few pounds for archive boxes and document wallets, and £3 to £10 for a lever arch file. A basic flatbed scanner costs around £50 to £150, which is enough for everyday post. Cloud storage is usually free in its limited version, then a few pounds a month depending on the space you choose. If you use a bank safe deposit box or specialist storage, expect around £50 to £250 a year depending on size and provider. The good news: sorting itself is free – and it's probably the best investment on the list.

So yes, paperwork can feel endless, but there's one reassuring thing about it: every document has its own deadline, and once you know that, the big clear-out becomes far less intimidating. Do a first sort this weekend – health and family in one pile, the rest to check – and remember that for a specific point, your insurer, accountant, solicitor or HMRC will be able to advise better than a general rule. You'll see: a lighter box means a lighter drawer – and a lighter head.
