Read the policy-specific methodology note

Market baseline

Reform's 2024 Contract proposed 20% tax relief on private healthcare and insurance. ABI data show private medical insurance and claims are growing.

  • Tax relief rate is 20%.
  • Private medical insurance coverage is rising.
  • NHS substitution is uncertain.

Core trade-offs

Insured households and private providers gain from a subsidy. The Exchequer loses revenue, and relief may subsidise care that would have happened anyway.

  • Private patients and insurers gain.
  • Treasury funds the tax relief.
  • NHS savings are uncertain.

Illustrative fiscal impact

+GBP 1.0bn to +GBP 8.0bn. Central estimate: +GBP 3.5bn.

  • Positive numbers mean public-finance pressure; negative numbers mean Exchequer savings.
  • 20% relief is the main scale marker.
  • Gross costs and receipt offsets are separated in methodology.
  • Behaviour and pass-through widen the range.
  • This is not an official costing.

Economic impact by 2027-28

  • Jobs: Private healthcare hiring rises, potentially drawing staff from the NHS.
  • Wages: Private-sector health wages may rise if capacity is constrained.
  • Prices: Private insurance and treatment prices may increase with subsidised demand.
  • GDP / productivity: May raise measured private activity, but NHS productivity gains are uncertain.

Assessment

The policy may expand private cover, but a subsidy is likely to pay for some care that would have happened anyway. If private capacity is constrained, prices and staff competition can rise. Any NHS benefit depends on genuine substitution away from publicly funded treatment.

Confidence: Low. The relief rate is clear, but eligible spending, uptake and NHS substitution are not specified.

Main risks

  • Deadweight cost: Tax relief may subsidise existing private spending rather than new NHS substitution.
  • Staff diversion: Private expansion may bid clinicians away from NHS work.
  • Price inflation: Subsidised demand can raise premiums and treatment prices if capacity is tight.

Safeguards

  • Restrict relief to treatments replacing NHS waits.
  • Monitor NHS staff movement to private providers.
  • Cap eligible claims and publish uptake data.
