When does going private
actually beat the NHS wait?
For routine MRI in the UK, the answer is “it depends on your region and your value of time”. This calculator stacks the typical regional NHS wait against a regional median private scan price, and applies your own £/week valuation of weeks-of-wait avoided. The verdict is mathematical — not moral.

Compares typical NHS MRI wait by region against a regional mid-price private scan to determine when going private clears your stated value of weeks avoided.

break-even verdict
NHS wait is the rational call.
The cost of going private exceeds your stated value of the weeks saved. Wait — and consider asking your GP about clinically-prioritising the referral if symptoms worsen.

NHS wait-time ranges from NHS England RTT statistics (last published quarter for diagnostic imaging). Private pricing from a typical 1.5T MRI scan (single body part) across published price lists of major UK private providers (Spire, BMI/Circle, Nuffield Health, InHealth). Your value-of-weeks-saved is whatever the time benefit is to you — earlier diagnosis, surgery date, return-to-work, or pain relief. Decision = (weeks saved × weekly value) vs private cost. Adjust as needed for multi-area scans (typically +20-40%).
How to set your “value of a week avoided”
This is the lever most people get stuck on. Four anchors that help:
- £0-20/week: mild symptoms, no functional impact, no career or insurance trigger. Wait NHS.
- £20-50/week: moderate symptoms causing some disruption but no urgency. Marginal — at most regions, the private cost will exceed the value of skipping 6-8 weeks.
- £50-100/week: significant impact on work, exercise, or quality of life. Often tips toward private at moderate NHS waits.
- £100+/week: material time-sensitive trigger (surgery date, insurance window, job offer requiring fitness clearance, persistent symptoms with rising risk). Almost always private at typical regional pricing.
Data sources: NHS England RTT statistics for diagnostic imaging (published quarterly), and aggregated private pricing from Spire, BMI/Circle Health, Nuffield Health, InHealth for 1.5T single-area MRI. Multi-area or 3T scans typically add 20-40% to the private cost. The calculator outputs are illustrative for budgeting and decision-making, not a quote — always confirm scan price and current NHS wait with your clinical team before deciding.
