One story (and the technical rules) that make full expensing safe

By Angelo Chirulli – angelo@vectigalistax.co.uk

Full expensing in one line: a 100% first-year allowance for new and unused main-rate plant & machinery purchased by a company and used in its trade. 

A 50% first-year allowance applies to many special-rate assets. (Cars are excluded.) Made permanent from expenditure incurred on/after 1 April 2023. 

The story

Monday, 08:10 — ABCDE Ltd (a very real-sounding but fictional UK company) kicks off a one-month capex refresh. 

Ops want a brand-new fiber laser (hire purchase), a shop-floor refit (lighting, power runs, extraction), a “new to us” forklift (refurbished), and a company van the MD may borrow at weekends. 

Finance say: “Let’s put full expensing on everything and close year-end strong.”

Tuesday, 14:20 — Paperwork lands.

Two refit packages are on short operating leases (“we can upgrade later”). The laser is on HP with a commissioning window that may slide into next period. The forklift is refurbished but “as good as new.” No one has checked eligibility beyond a quick spreadsheet tick.

Thursday, 18:45 — Ten-minute review, four red flags.

1. Refurbished forklift. Full expensing requires new and unused assets; second-hand/refurbished does not qualify. (AIA may.)  
2. Operating leases on refit kit. Assets acquired for leasing are generally excluded from first-year allowances (including FE). Operating leases also don’t confer ownership for capital allowances (HP/buy can). Background plant within a building can be an exception. 
3. Hidden special-rate items. Parts of the refit (integral features like fixed electrics/extraction) sit in the special-rate pool; under FE they typically get 50% in year one unless you deploy AIA first.
4. Commissioning after year-end. For HP, relief links to the asset being brought into use; miss the period and you miss the year-one deduction. (Expenditure must actually be incurred on/after 1 April 2023; timing rules matter.)

Silence in the room. Then the FD asks: “Give me a rule we can run before we sign.”

The Coffee Test (30 seconds before you approve the purchasing order)

Three questions:

1. New and unused? (Not refurbished/second-hand).
2. Owned (buy/HP), not an operating lease?
3. Delivered and brought into use this accounting period?

Three “Yes” → full expensing likely fits.
Any “No” → use the correct route (AIA, timing change, or standard allowances) instead of forcing FE. 

We run the test line-by-line. In five minutes the plan rewrites itself—without changing the shopping list.

The technical fixes we made (and why they’re right)

• Forklift (refurbished) → AIA, not FE. AIA often gives 100% in year one (subject to the £1m cap and normal restrictions). 
• Refit (mixed contracts) → core items switched to HP (ownership + “brought into use” → FE eligible if main-rate and new); non-core stayed on lease, accepting no FE (unless falling under the background plant exception). 
• Special-rate elements (e.g., integral features) → we used AIA first to reach 100% this year, then applied FE to the remaining main-rate spend. (FE is 100% for main-rate, 50% for many special-rate assets.)
• Laser (HP) timing → locked commissioning before period end; where impossible, adjusted forecasts and QIPs rather than over-claiming. (FE claims must reflect when expenditure is incurred and, for HP, in-use status.) 

Why we avoided a future headache: FE has disposal symmetry—sell FE-claimed kit later and you can face an immediate balancing/disposal charge (often equal to proceeds where 100% FYA was claimed). Planning holding period and likely exit matters.

Evidence pack (the “boringly good” file)

• Supplier statement that the asset is “new and unused.”
• Contract type (buy/HP vs operating lease), with HP terms attached.
• Delivery and (if HP) commissioning evidence dated within the period.
• Asset classification (main-rate vs special-rate) and the chosen route (FE / 50% FYA / AIA / SBA).
• If any private/mixed use risk (e.g., a van): a one-page usage policy and apportionment note.
• A line noting the likely disposal path (to pre-empt FE clawback mechanics).
  (These mirror HMRC’s public guidance and internal manual emphasis on “new & unused,” timing, and claim route.)  

The Board Grid (paste this into every capex pack)

Asset | New/used | Pool (main/special) | Route (FE / 50% FYA / AIA / SBA / none) | Ownership (buy/HP/lease) | Delivery & “in-use” date | Mixed use? | Disposal plan

Complete it before you sign. It prevents most FE errors and defends the file when challenged.

Quick technical FAQs

• Who can claim FE? Only companies (not LLPs/sole traders).  
• Cars? No (other vehicles may qualify for FE; zero-emission cars can have a separate 100% FYA under different rules).  
• Leasing? Assets bought to lease out are generally excluded from FE (exception: some background plant within a building). Operating leases don’t give capital allowances to the lessee. 
• Period & permanence? FE applies to qualifying spend from 1 April 2023, and the regime was made permanent (policy statement). 
• Double-claiming? You cannot claim both FE and AIA on the same expenditure. Choose the optimal sequence across the asset list.  

Bottom line

Full expensing isn’t a mystery—it’s a checklist discipline. Ask the Coffee Test before you sign; route special-rate items through AIA first; keep timing and ownership clean; plan the exit. 

Do that, and you’ll get the cash-flow outcome and a file that stands up on review.
