I regularly help small retailers untangle questions about capital allowances, and one of the topics that comes up again and again is: can you claim for second‑hand plant and machinery? The short answer is usually yes — but there are a few practical checks and bookkeeping habits that make the difference between a smooth claim and an HMRC query. Below I walk through what to look for, how to make the claim, common pitfalls for retailers, and simple recordkeeping steps you can implement today.

What counts as “plant and machinery” for a small retailer?

In retail, plant and machinery (P&M) covers the tangible items you use in the business to trade — shelves, racking, display units, EPOS terminals, freezers and fridges, shop signage, hand‑tools, and workshop equipment if you repair or make goods. It also includes some vehicles (vans) used to deliver goods, but not cars used mainly for staff personal use. Importantly, structural elements (walls, floors, integral features like fitted lighting or built‑in air conditioning) are treated differently and often fall under other allowances or are excluded.

Can you claim capital allowances on second‑hand P&M?

Yes — second‑hand P&M bought purely for business use is generally eligible for capital allowances in the same way as brand‑new items. HMRC doesn’t insist that the asset must be new. What matters is:

  • the asset is used in the business,
  • it is genuinely P&M (not a non‑qualifying fixture or building element), and
  • you have evidence of the purchase and the price you paid.

    • That said, there are practical and tax nuances to be aware of (see below).

    Practical checks before you buy a second‑hand asset

    Before completing a second‑hand purchase — especially for higher value items like refrigeration units, display cabinets or delivery vans — I recommend you:

  • Get a written invoice or receipt showing date, seller’s details and price paid. Cash sales without a receipt are a red flag for HMRC queries.
  • Check whether the seller is a connected person (a previous owner in the same group or a related trader). Purchases from connected parties can raise specific rules around how the claim is treated.
  • Confirm the asset’s condition and expected useful life. While allowances are not based on “useful life” for tax purposes in the same way as accounting depreciation, it helps you decide whether to buy and which pool to put it in.
  • Note serial numbers, model details and photos at the time of purchase — they’re great evidence if HMRC asks for proof you actually bought and used the asset in the retail business.

    • Which allowance to claim — a quick decision guide

    When you buy qualifying P&M you normally choose between:

  • claiming the full cost in the accounting period using an allowance such as the Annual Investment Allowance (AIA) if eligible, or
  • putting the asset into the relevant capital allowances pool and claiming writing‑down allowances (WDA) over time.

    • My practical way to decide for a second‑hand item:

  • If the asset is low value and you can afford the cash flow hit, using AIA (if available and if the asset qualifies) simplifies things — you get the tax relief upfront.
  • If you’re unsure about future trading (or you might sell the asset soon) consider pooling and claiming WDA instead; selling assets requires disposal adjustments and can trigger balancing charges which you’ll need to manage.

    • Note: AIA and other reliefs change over time. Check the current HMRC position or ask your accountant about the up‑to‑date annual allowance limit.

    Special rules and common pitfalls for retailers

  • Cars vs vans — Be careful: cars (even second‑hand) have restricted capital allowance rules. Vans used genuinely for business have more favourable treatment; check the vehicle’s classification before you claim.
  • Integral features — Built‑in shop fittings that are part of the building (for example, permanently installed partitioning or heating) can be treated differently or excluded. Freestanding shelving is usually P&M; fitted shelving bolted to the structure may need closer scrutiny.
  • Purchases from related parties — Transactions between connected persons can attract special rules on the amount of qualifying expenditure and how any balancing charge is calculated when you dispose of the asset. Keep clear paperwork and consult if the buyer/seller are connected.
  • Second‑hand from abroad — If you buy from overseas, be aware of VAT and customs implications which affect your cost base for allowances. Bring evidence of import documents and any duties paid.

    • How to claim — the steps I follow with clients

    Here’s the practical workflow I use when helping small retailers claim allowances on used P&M:

  • Identify and list the qualifying assets purchased during the period — keep make/model/serial info.
  • Decide whether to apply AIA (or equivalent) or to place items in the capital allowances pools. I project tax cashflow both ways to see which is better.
  • Record the qualifying cost in the business accounts and tag the transaction in your bookkeeping software (Xero, QuickBooks, FreeAgent — label it “P&M purchase”).
  • Complete the capital allowances entries on your tax return: self‑assessment (SA100) for sole traders, or the company tax return (CT600) for limited companies. Your tax software or accountant will put WDA or AIA figures into the right boxes.
  • Keep asset registers and supporting documents for at least six years (HMRC can go back to review), including invoices, bank transfers, photos and any warranty or service records.

    • Recordkeeping checklist

    DocumentWhy it matters
    Invoice/receiptProves cost, date and seller
    Proof of paymentShows money left the business
    Photos/serial numbersEvidence asset exists and is in your control
    Sales contract (if from connected party)Explains relationship and price setting
    Service/maintenance recordsUseful if HMRC asks about use or condition

    Example scenarios I see in retail

    Case 1 — A small boutique buys a second‑hand EPOS terminal from a local merchant. It’s freestanding, used only for the business and cost is modest. I usually advise claiming it under AIA (if within limits) — immediate relief, simple bookkeeping, no pooling headaches.

    Case 2 — A convenience store purchases a large second‑hand refrigerated display cabinet. This is higher value and may be classed as special rate (depending on whether it contains integral features). Here I review whether it should go into the special pool and plan for potential WDA; I also check the electricity/installation works and whether any of that is qualifying P&M.

    Case 3 — Buying a used van for home deliveries. Vans can qualify but cars don’t. I check the vehicle classification and usage logs and ensure VAT is handled correctly if the seller was VAT registered.

    When to get specialist help

    Most second‑hand purchases you can handle with sensible records and a clear entry in your bookkeeping. However, get an accountant involved if:

  • the item is expensive and you’re unsure about classification,
  • there’s a connected‑party transaction, or
  • you plan to sell the item shortly after purchase (disposals cause balancing adjustments).

    • Working with an accountant early can prevent mistakes that are time‑consuming to correct during an HMRC enquiry.

    If you want, I can help you run through a specific purchase — send the invoice and a photo and I’ll tell you the simplest way to treat it for capital allowances and how to record it in your accounts.
