Covid Swab Testing

Cavendish Health Centre are delighted to now be able to offer Covid swab testing on a private basis. This is for people who do not have any symptoms of covid-19. The results will be received with 24hours of your swab reaching the testing laboratory.


The Covid swab test is to confirm whether you have coronavirus (Covid-19) now and cannot tell you about past infections or immunity. The test may be undertaken on a private basis for: 

  • People who may need it prior to travel (we can provide a flight letter too) 

  • People who require it for their work  

  • People who want an asymptomatic screening test

  • People who want a test on return to the UK from abroad.

We recommend that people who have symptoms of Covid try to access a test on the NHS for free via the website or by calling 119. Unfortunately we cannot offer NHS Covid swab tests at this time. 

What the swab test involves:

The test involves taking a swab of the inside of your nose and the back of your throat, using a long cotton bud. This can be unpleasant but isn’t painful. 

You can do the swab yourself (if you are aged 12 or over) or someone can do it for you. Parents or guardians have to swab test children aged 11 or under. 

The kit comes with an instruction sheet to guide you through this process. 

To view this instruction sheet please click here

Please note it is important to follow the instructions carefully to take a good swab so you do not have an inadequate result. If this happens you would need to repeat the test at your own cost.


For an individual NHS Cavendish Health Centre patient: £100 

For an individual not registered at Cavendish Health Centre: £110 (Please note you can register at the practice by clicking here

Additional cost for a flight letter: £10 

For a household of 4 people not registered at Cavendish Health Centre: £420

(If you work in an office and require multiple tests or you require repeated tests please contact us for a quote)

Note: Prices include postage to the laboratory via Royal Mail Special Delivery Service although a courier service is also available - please contact us to discuss if you wish to have this service.

For NHS patients registered at Cavendish Health Centre ONLY we offer a combined flight letter for both swab results and to confirm your COVID-19 vaccination status for an additional £20
