Tens of thousands of expat pensioners may return to the UK to use the NHS after Brexit – unless a deal can be done to let them keep receiving care abroad, a think tank has warned.
The Nuffield Trust estimates the cost of treating them – on home soil, rather than abroad – could double to £1bn.
Currently, the UK gives around £500m a year to EU countries that care for Brits who have retired abroad.
Last year, spending on the NHS in England was around £120 billion.
The warning from the Nuffield Trust came as Health Secretary Jeremy Hunt told a newspaper that the NHS could suffer if Brexit “goes wrong”.
Around 190,000 British pensioners live abroad.
Under the EU reciprocal “S1” scheme, British pensioners have the right to go to any other EU member state and receive the same health care rights as the local population.
According to the Nuffield Trust, it may not be easy to continue with this agreement after Brexit.
If all of these pensioners decided to return to the UK – a big if – they could be expected to fill 900 NHS hospital beds a year, it says.
The NHS would need around 1,600 more doctors, nurses and other workers to provide the care, it estimates.
Also, hospitals could end up short-staffed if migration of workers from the EU slows or stops post-Brexit.
And access to medicines could also become more difficult if the UK leaves the EU’s medicine licensing system.
But there could be gains too post-Brexit, the Nuffield Trust says.
When the UK leaves the EU it could stop paying EU membership fees. Money from this saving could be used by the NHS.
Nuffield Trust spokesman Mark Dayan said: “It is possible that extra funds could be found for the NHS from any cancellation of Britain’s EU membership fees.
“But whether or not these benefits will outweigh the significant staffing and financial costs Brexit may impose on already stretched services remains to be seen.
“That depends largely on the NHS being recognised as a significant priority as we enter some of the most important negotiations in Britain’s history.”
The British Medical Association urged politicians to keep the health service and its patients at the forefront during Brexit negotiations.
A Conservative party spokesman said safeguarding the rights of UK nationals in the EU and EU nationals in the UK was “one of our first priorities for the Brexit negotiations”.
Liberal Democrat leader Tim Farron said: “A brighter future is possible. We will stand up to a bad Brexit deal that would hit the NHS hard, and give people the final say with a chance to remain in the EU.”
Labour have not commented on the Nuffield Trust’s report, but have accused the Conservatives of “starving” the NHS.
