Saliva tests now available that are 95ish% the same results as the tonsil/nose tests. https://www.thejournal.ie/saliva-pcr-covid-19-test-5543680-Sep2021/
308 test subjects isn't exactly a high number, with just under 5% of the results discordant and all of those in symptomatic patients.

Said to be consistent with other studies (but I don't know which) which might mean the small sample isn't too much of a worry.

Isn't this a better match than the lateral flow test which is around 10% discord IIRC?

It's not being designed to replace the lateral flow test though. It's the PCR test they want to replace with it.

Given that such kits are on the market already(£4 upwards), at cost to the person testing, is it actually better than what it seeks to replace. Some require pairing with an app to get the full result.

Looking at the gov.uk dashboard, it's now clear that the peak of this last 'swell' which started on 30 Jul) was on 3 Sep. The reporting date peak was on 5 Sep and the by specimen date of 3 Sep can be relied on. Cases are about 25% down on the peak and falling. So we might reasonably expect the peak of hospital admissions to be about today.
I'd observe there seems to have been no sign that the return to school (England) over the last 10 days has had any apparent effect on infection rates, despite all the non-science based pessimists.
We'll have to see if the return to universities cause reverse to the trend over the next fortnight. Certainly last September that 2020 cohort (unvaccinated of course) made a significant contribution to the slow ramping up last autumn. If students are academically good enough to benefit from a university education I hope they've also been astute enough to get vaccinated, in both their own interest and for the good of their peers, as well as the wider community.

Although the peak of infections being the 3rd September would be as all pupils were having their return to school 3 supervised lateral flow tests so not surprising. At my school, 2.65% of pupils tested positive and were therefore prevented from returning to school in the first week.

Isolate or not too isolate . Scenario (not mine ) , young child in a family , runny nose not feeling too great. Parents decide to send child for a PCR test. One parent is a teacher, school send her home along. With the other two children in the family to isolate and await results. Should they all be isolating if parents double jabbed and have no symptoms ? Lateral flow tests are negative .
Scogov say isolate if suspected case or in the same household. I’m sure that’s not the case now? My employer also says otherwise unless been contacted.

Since some date in August, here in England the double-jabbed and the under 18s don't need to isolate (if asymptomatic) even if the close contact is a household one and has +ve PCR. Don't know what the rules are in Scotland though.

My personal opinion is that, TBH, I think that if you can self-isolate while awaiting contact's PCR (and later if the contact's PCR is +ve) it's wise to do so, even if you remain asymptomatic throughout. You never know which person you might be in contact with is immunosuppressed, or is going home to an immunosuppressed loved one.
Daily LF tests can be of some reassurance and you should, of course, wear a decent-quality mask whenever in the close company of others so that you are minimising the exposure of others to your possibly-infectious exhalations ...
