Which allowance you get, and why it matters
Buy equipment and you cannot simply deduct it like a normal expense — you claim capital allowances, and which one applies changes the timing enormously. Sometimes all of it lands this year; sometimes a fraction a year for a decade.
Full expensing gives 100% on new main-rate plant and 50% on new special-rate assets. It is uncapped and permanent, and it is for companies buying new and unused assets only. The Annual Investment Allowance gives 100% on up to £1,000,000 a year, covers both pools, and is open to unincorporated businesses and to second-hand kit. For most practices the AIA does everything full expensing would have.
In this sector the spend that matters is typically dispensing robots, controlled drugs cabinets, medical fridges, consultation room fit-out, tills and PMR hardware.
A robot is plant. The building work around it is not.
An automated dispensing system is main-pool plant, and a company buying new gets 100% in year one. But installing one usually means structural work, a reinforced floor, new power and often a reconfigured dispensary — and those are integral features or, in some cases, not qualifying at all.
The consultation room a Pharmacy First service needs is the same story: the furniture and the IT are plant, the partition walls and the ventilation are not.
Medical fridges are worth itemising
Pharmacy fridges are relatively cheap individually and add up quickly across a group, and they are unambiguously main-pool plant. So is the controlled drugs cabinet, despite being bolted to the structure — it is apparatus of the trade rather than part of the premises.
