Capital Allowances for Medical Equipment: What Healthcare Practices Can Claim

When a healthcare practice invests in medical equipment — whether that is a new dental chair, an ultrasound scanner, a pharmacy dispensing robot, or a GP surgery’s consulting room fit-out — the full cost rarely appears as a deduction in the year of purchase. Instead, the tax relief comes through a system called capital allowances. Understanding which allowances apply, how much can be claimed, and when is one of the most valuable pieces of tax planning available to healthcare businesses in the UK.

This guide explains the capital allowances framework as it applies to healthcare practices in 2026, covers the most common types of qualifying equipment, and highlights the planning opportunities and pitfalls that practitioners most frequently encounter.

What Are Capital Allowances?

Capital allowances are the UK tax system’s mechanism for giving businesses relief on capital expenditure — that is, spending on assets that will be used in the business over more than one year. Unlike day-to-day running costs (which are deducted in full in the year incurred), capital spending on equipment, machinery, and certain fixtures must be deducted through the capital allowances system rather than directly through the profit and loss account.

For healthcare practices, this distinction matters enormously. Medical equipment, dental chairs, imaging machines, consulting room furniture, computer systems, and practice fit-out costs are all capital in nature. Without capital allowances, none of these costs would reduce your tax bill in a straightforward way. With the right allowances, much or all of the expenditure can be relieved in the year it is incurred.

Capital allowances are available to sole traders, partnerships, limited companies, and LLPs — so they apply across the full range of structures through which healthcare practices operate. If you are unsure which structure is right for your practice, our guide on how doctors can benefit from incorporating their private practice is a useful starting point.

The Annual Investment Allowance: 100% Relief in Year One

The Annual Investment Allowance (AIA) is the most important capital allowance for most healthcare practices. It allows businesses to deduct 100% of qualifying capital expenditure in the year of purchase, up to a set annual limit.

The current AIA limit is £1,000,000 per year. This limit has been permanently set at this level since April 2023, which means the vast majority of independent healthcare practices — GP surgeries,dental practices,pharmacies, private clinics, care homes — can claim full first-year relief on virtually all their equipment purchases.

What qualifies for AIA:

• Medical and dental equipment (chairs, scanners, sterilisers, autoclaves, X-ray machines, ultrasound units, ECG machines)
• Dispensary equipment and pharmacy automation
• IT hardware, computers, tablets, and clinical software (if capitalised)
• Consulting room furniture and fitted units
• Surgical instruments and diagnostic tools
• Physiotherapy and rehabilitation equipment
• Optometry equipment
• Laboratory equipment
• Air conditioning and ventilation installed as plant

What does not qualify for AIA:

• Cars (they have their own separate allowances)
• Land
• Buildings themselves (though fixtures within buildings may qualify)
• Assets acquired for leasing out to others

Key Point: The £1,000,000 AIA limit applies per business, not per individual. For partnerships or group structures, the limit is shared between connected entities. If your practice structure involves multiple entities, this needs careful planning — speak to our business tax team to review your position.

First Year Allowances: The 40% FYA for Special Rate Assets (Rate effective after April 2026)

Certain assets that do not qualify for the AIA — specifically those falling into the “special rate pool” — qualify for a 50% First Year Allowance (FYA),Note:40% FYA is going to be effective from April 2026. instead of being written down at just 6% per year under the standard special rate rules.

Special rate assets most relevant to healthcare practices include:

• Integral features of a building: electrical systems, cold water systems, heating and ventilation systems, lifts and escalators, solar panels
• Long-life assets with an expected working life of 25 years or more
• Thermal insulation added to existing buildings

In practical terms, a healthcare practice fitting out a new premises will often have a significant proportion of expenditure falling into integral features — the wiring, the plumbing, the HVAC system. Previously, these were written down at just 6% per year (meaning it would take decades to get full tax relief). The 50% FYA, introduced in April 2023 alongside Full Expensing, substantially improves this position for incorporated practices.

Note for Unincorporated Practices: The 50% FYA and Full Expensing (see below) apply only to companies paying corporation tax. Sole traders and partnerships continue to use the AIA for plant and machinery (including integral features up to the AIA limit) and the special rate pool at 6% per year for any surplus above the AIA. Our personal tax team can advise on the best approach for unincorporated practices.

Full Expensing: 100% Relief for Companies

For healthcare practices operating as limited companies, Full Expensing — introduced in April 2023 and made permanent in the Autumn Statement 2023 — allows 100% of expenditure on new, unused plant and machinery to be deducted in the year of purchase, with no upper limit.

This is a significant improvement over the AIA for larger incorporated practices that spend more than £1,000,000 on capital equipment in a year, or that want certainty of first-year relief without the AIA cap applying across connected entities. If your practice is not yet incorporated, read our article on how doctors can benefit from incorporating their private practice to understand whether a company structure could work in your favour.

Full Expensing covers:

• New plant and machinery that would otherwise go into the main pool (14% per year)
• The 50% FYA covers new special rate pool assets

Full Expensing does not apply to:

• Second-hand or used equipment
• Cars
• Assets used partly for non-business purposes
• Sole traders or partnerships

For a private hospital, a group dental practice, or a healthcare company investing heavily in new equipment, Full Expensing can produce very large first-year tax deductions that substantially reduce or eliminate the corporation tax liability for that year.

Writing Down Allowances: When AIA Is Exhausted

For expenditure above the AIA limit, or for assets that do not qualify for full first-year relief, the remaining balance is added to a capital allowances pool and written down at a percentage each year.

Main pool rate: 14 % per year — covers most plant and machinery including standard medical equipment, computers, and furniture.

Special rate pool: 6% per year — covers integral features and long-life assets.

Writing down allowances (WDAs) are calculated on the reducing balance, so the relief diminishes each year but never fully extinguishes. For a healthcare practice with a significant pool balance, this creates a long tail of deductions that continues for many years after the original purchase.

Practical Example:

A GP surgery buys a new ECG machine for £12,000. It claims AIA of £12,000 in year one — full tax relief immediately. If instead it had a pool balance of £50,000 of existing equipment, the WDA at 14% would give relief of £7,000 in year one (£50,000 × 14%), leaving a pool balance of £43,000. In year two the WDA would be £6,020 (£43,000 × 14%), leaving a pool balance of £36,980, and so on. Good bookkeeping for healthcare is essential to track these pool balances accurately year on year.

The Small Pools Allowance

If the balance in either the main pool or special rate pool falls below £1,000 at the end of a period, the entire remaining balance can be written off in that year under the small pools allowance. This is a minor but useful simplification that healthcare practices should use routinely to avoid carrying forward trivial pool balances indefinitely. Your accountant should be checking this as part of your annual business tax compliance work.

Structures and Buildings Allowance: Claiming on Your Premises

If a healthcare practice constructs a new building, converts an existing building, or carries out qualifying renovation works, it may be eligible for the Structures and Buildings Allowance (SBA).

The SBA provides tax relief at a flat rate of 3% per year on qualifying construction or renovation expenditure, spread over 33⅓ years. It applies to commercial properties including:

• New-build GP surgeries or dental practices
• Conversion of premises into a healthcare facility
• Extensions to existing practice buildings
• Fit-out costs that are structural (as opposed to plant and machinery, which is claimed via capital allowances)

The distinction between plant/machinery and structures matters greatly. A dental chair bolted to the floor is plant — claim via AIA. The floor itself is a structure — claim via SBA at 3%. The partition walls between consulting rooms are structural — SBA. The electrical system powering those rooms is an integral feature — 50% FYA or special rate pool.

Getting this split right when fitting out a new practice can make a material difference to the tax position in the early years. Our business tax specialists can carry out a formal expenditure review to ensure the split is correctly identified and documented.

Action Point: If your practice has carried out any building works in the last two years without a formal capital allowances review — particularly a Structures and Buildings Allowance election — you may have missed relief that cannot easily be recovered retrospectively. Contact our team to discuss a review.

Capital Allowances on Second-Hand Equipment

Healthcare practices frequently purchase second-hand medical equipment — refurbished dental chairs, pre-owned imaging equipment, used dispensary systems. The capital allowances treatment depends on the type of allowance being considered.

• AIA — available on both new and second-hand plant and machinery (subject to anti-avoidance rules for connected parties)
• Full Expensing — applies to new, unused equipment only; second-hand assets do not qualify
• Writing Down Allowances — available on both new and second-hand equipment added to the pool

For most practices, second-hand equipment costing under the AIA limit will still attract full first-year relief via the AIA. The restriction on Full Expensing for second-hand assets primarily affects large incorporated practices buying expensive used equipment. If you are unsure how to classify a recent purchase, our healthcare accounting team can advise.

Claiming Capital Allowances on Cars Used in Healthcare

Many healthcare professionals use a car partly or wholly for their practice — visiting patients, travelling between sites, or attending training. Cars have their own capital allowances regime, separate from plant and machinery.

Car allowances are based on CO2 emissions:

• 0g/km CO2 (electric vehicles): 100% First Year Allowance — full relief in year one
• 1–50g/km CO2 (low emission): 18% per year (main pool)
• 51g/km+ CO2: 6% per year (special rate pool)

A healthcare professional buying an electric vehicle for use in their practice can claim 100% relief in year one — making the switch to electric financially compelling from a tax perspective as well as an environmental one. This is one of several tax planning strategies for doctors worth exploring before the end of your tax year.

Private use restriction: If the car is used partly for private journeys, the capital allowance is restricted proportionately. A car used 70% for business and 30% privately can only generate a deduction equivalent to 70% of the allowance available. Detailed mileage records are essential to support this claim.

Warning: HMRC scrutinises car capital allowance claims carefully, particularly the business/private use split. Sole traders and partners should maintain a contemporaneous mileage log throughout the year, not reconstruct one at year-end. If you are a locum or sole trader, our personal tax team can help ensure your records are HMRC-ready.

Timing: When Is Capital Expenditure “Incurred”?

For capital allowances purposes, expenditure is generally treated as incurred on the date the obligation to pay becomes unconditional — usually the date of delivery or the date a contract is entered into, whichever creates the legal liability. For most straightforward equipment purchases, this is the invoice date or delivery date.

Why timing matters:

• If a practice has a 31 March year-end and orders a new piece of equipment in late March, ensuring delivery and invoicing before the year-end secures the allowance in the current year
• Conversely, delaying a purchase until just after year-end pushes the relief into the next period — which may be preferable if profits are lower that year
• For hire purchase agreements, the capital allowances are typically available from the date the agreement begins, even if payments continue over several years

A proactive accountant will discuss planned equipment purchases with you before year-end, not after, to ensure timing is optimised for your tax position. This kind of proactive planning is central to how our specialist healthcare accounting team works with clients throughout the year.

Special Considerations for Different Practice Types

GP Surgeries and Primary Care

GP practices operating as partnerships are unincorporated, meaning they use AIA and WDAs rather than Full Expensing. The AIA limit is shared across the partnership as a whole, not per partner. Equipment costs are substantial — consulting room fit-outs, ECG machines, spirometers, blood testing equipment, IT systems — and should be reviewed annually to ensure full AIA claims are being made.

NHS-funded equipment may require a different treatment depending on whether ownership transfers to the practice. If the NHS retains ownership, no capital allowance is available to the practice. If the practice purchases the equipment itself (even partially funded by NHS grants), the full cost may qualify — though any grant received reduces the qualifying amount. Accurate bookkeeping for GP practices is essential to track the ownership and cost basis of all equipment correctly.

Dental Practices

Dental practices typically have high capital expenditure on chairs, compressors, autoclaves, X-ray units, and CBCT scanners. The AIA generally covers all of this comfortably. For large group dental practices structured as companies, Full Expensing makes significant equipment investment even more attractive from a tax perspective.

Mixed NHS/private dental practices should note that if the practice is partly exempt for VAT purposes, any VAT on capital equipment that cannot be recovered affects the capital allowances base cost (i.e., the irrecoverable VAT forms part of the capital cost on which allowances are claimed). Our VAT specialists can help ensure the partial exemption calculation is correctly feeding into your capital allowances position.

Pharmacies

Pharmacies often invest in dispensing automation, MDS (monitored dosage system) equipment, refrigeration units, and point-of-sale systems. All of these qualify as plant and machinery. Pharmacy fit-out costs should be carefully split between plant (AIA/Full Expensing) and structures (SBA) to maximise early relief.

Pharmacy owners should also read our related guide on understanding pharmacy business expenses and what is tax-deductible, which covers the revenue expenditure side of the same equation.

Private Clinics and Hospitals

Larger private healthcare operators investing in MRI scanners, CT equipment, surgical theatres, or patient monitoring systems face the most complex capital allowances position. Full Expensing is highly valuable here for incorporated entities. A formal capital allowances review — including a fixtures and fittings survey of the building — is almost always cost-effective at this scale.

Care Homes

Care home capital allowances are often underoptimised. Fit-out costs including resident room furniture, communal area fittings, kitchen equipment, and laundry facilities all qualify as plant and machinery. The building itself attracts SBA if constructed or significantly renovated. Our healthcare accounting specialists regularly conduct capital allowances reviews for care homes and consistently identify material unclaimed relief.

Capital Allowances on Practice Acquisitions

When a healthcare practice acquires an existing business — buying a dental practice, apharmacy, or a care home — the capital allowances position needs careful attention.

The buyer and seller can jointly elect to fix the value of fixtures at an agreed amount. This election determines how much capital allowance the buyer can claim going forward. Without this election, the buyer’s claim may be restricted or lost entirely.

Practical guidance for practice buyers:

• Always instruct a capital allowances specialist as part of the purchase due diligence
• Ensure the sale and purchase agreement (or a side election) fixes the fixtures value
• Identify all plant, machinery, and integral features within the building being acquired
• Check whether the seller has pooled the assets — if not, the buyer’s claim may be limited to £1

This is an area where getting professional advice before exchange of contracts is essential. Once the deal is done, the opportunity to optimise the position may be gone. Contact our team before you exchange on any practice acquisition.
