A number of very good schools near me (think Times list level) have noted a significant drop in English results in the last couple of years.
One has started doing remedial lessons for boys doing well in maths but with a significant asymmetric disparity in their English.
Another, a grammar school with 11+ entry, has started doing phonics classes. This is a girls school.
It's been noted by government too. They announced this last month:

Year 8 pupils in England will have to sit reading tests at school under government plans due to be released this autumn, the BBC understands.
The mandatory tests, first reported by Schools Week,, external would aim to check their progress two years into secondary school.
It comes amid concern that a quarter of Year 6 pupils are not meeting expected reading standards and the English GCSE pass rate has slipped.
There's a few potential reasons for this. COVID is one of them - these kids missed a huge proportion of primary school when building blocks for reading are formed. DS is yr6 and his year were reception. They never learnt to sit still and were plonked with devices to manage behaviour from an early age.
When COVID started I was helping read with the then yr5s. DS year group are way behind that. From everything I've heard this years Key Stage 2 results are going to be interesting on a national level too.
Locally too, there's been a significant migration of kids to the area who have English as a foreign language. A lot of Ukrainians and Hong Kong Chinese were attracted to the area and that's had a big impact on house prices and school places.
The Hong Kong Chinese group are particularly interesting as they were desperate for good school and are affluent so a large number were tutored within an inch of their life to pass tests, but still can't actually speak English or write as well as you think. They have a good basic grasp of English in terms of being able to learn by rote and answer questions well enough to pass a test but not necessarily fully understand (particularly speaking). They become completely unstuck at words they've not been exposed to previously whilst those who have done phonics can ultimately word out the word. These kids in particular do a lot better in maths and science and English based subjects where a lower level of understanding English is sufficient and they aren't judged on spelling and punctuation.
I suspect there are pockets around the country with notable different patterns of migration which are impacting on English in particular.
It's not something I'm surprised by.
Nor would I look at an individual school based on results and go 'shit they are failing'. I'd be looking at the area and whether something in particular has happened and being aware this is something of a national trend anyway. This potentially something you aren't going to avoid by looking at other schools. Indeed a school with 'bad' English result might actually be doing exceptionally well given the local demographics, in terms of progress.
