Check the below link in UKVI, it clearly states that we can use the expired certificates in case if it was used for your previous entry clearance --

If your qualification expires
Some qualifications on the Home Office’s list expire after 2 years.
You can use an expired test if:
- you’re applying for citizenship and your B1 level qualification was accepted when settling in the UK
- you’re applying to settle in the UK and your qualification was accepted for another UK immigration application, eg when you got permission to enter
You need to confirm your qualification with either a certificate or by checking that your results can be viewed online.
