It said there are no NHS ear wax services in Birmingham & Solihull, Cornwall & Scilly Isles, Dorset, Mid & South Essex, NW London, SW London and Suffolk & NE Essex.

This affects millions of people who have to fork out if they want the treatment.

RNID’s director of health Crystal Rolfe said: “For the 10 million people who live in areas where there is no provision, the only option is to pay for it, which we know can cost up to £100 for just one procedure.

“Previous research shows that 26 per cent of people say they wouldn’t be able to afford that, partly because some people need to have earwax removed several times a year.”

​A build-up of earwax can interfere with hearing and cause symptoms like dizziness and sickness.

However, DIY methods to remove this such as using cotton buds or hairpins can be incredibly dangerous.

Mrs Rolfe continued: “For most people, it’s a self-cleansing mechanism and the wax just comes out on its own.

“If it’s got stuck in your ear, then you should go and see a GP, who might sometimes suggest olive oil drops in the first instance.”
