Plant and Machinery
Fixed AssetsThis Fixed Assets code records the cost of plant and machinery owned by the business for long-term use, rather than for resale. As an asset account, it normally carries a debit balance: debit entries increase the balance (for example, when a new asset of this type is purchased), and credit entries decrease it (for example, when the asset is sold or disposed of).
Real-world examples
Manufacturing
A manufacturer buys a CNC machining centre for the factory floor, invoiced at £96,000 (£80,000 net). The entry is a debit of £80,000 to 0020 (Plant and Machinery), a debit of £16,000 to 2201 (Purchase Tax Control Account), and a credit of £96,000 to 2100 (Creditors Control Account) — reclaimable in full as with most business equipment. Machinery like this is also usually where most of a manufacturer's capital allowances claim sits at year end, since the Annual Investment Allowance lets qualifying spend like this be deducted from taxable profit in the year it's bought, rather than spread over many years.
Food and hospitality
A restaurant fits out its kitchen with commercial ovens and an extraction system, invoiced at £14,400 (£12,000 net). The entry follows the same pattern at a smaller scale: a debit of £12,000 to 0020, a debit of £2,400 to 2201, and a credit of £14,400 to 2100. It's a meaningful capital outlay for a single site, but nowhere near the scale of a production line — the difference between industries here is mostly one of magnitude rather than mechanics.
Professional services
A consultancy or agency essentially never uses this code — it owns no plant or production machinery at all. Any equipment it does buy (laptops, monitors, office kit) belongs in Office Equipment (0030) instead, so 0020 typically sits permanently at zero on a services firm's balance sheet.
Commonly confused with
Code 0020 (Plant and Machinery) is easy to mix up with code 0021 (Plant/Machinery Depreciation). Code 0020 is the original asset cost, which only changes when an asset of that type is actually bought or sold, while 0021 is the accumulated depreciation — a contra-asset that only ever moves at the year-end depreciation run. Posting to the wrong one understates the asset's net book value without anyone noticing until the next audit.
What a mis-posting here costs you
Posting plant and machinery-related spend to the wrong Fixed Assets code doesn't change the total value of assets on the balance sheet, since it's still capitalised either way — but it does distort the fixed asset register and the depreciation schedule that runs off it, which is usually what alerts an accountant that something's misclassified at the year end.
