I stated that it was on Channel 37, so I am correct.

Hi - I am an aerial installer and since the retune' on sept 4th a lot of my customers have lost channels. I noticed that some channels are being transmitted at -10db power - these are the channels that are missing. Is there any plan to transmit these on full power ?
If not, what will I tell my customers who before this , had all the channels...?
Thanks

Oh dear!
Whilst the information on some of these transmitter pages isn't always correct (there are 1100+ transmitters in the UK & the site owner has not been able to keep up for all the 700MHz clearance changes) on this occasion the information is correct. The -10dB for the COM muxes is in relation to the PSB muxes as you've no doubt deduced, and that has not changed with the retune event. They always have been 2kW cf. the PSBs 20kW.
Refer to the UTV pdf document which can be downloaded towards the bottom of Freeview | All your favourite TV shows, all in one place and all for free corporate/platform-management/700mhz-clearance/clearance-events-2020">Clearance events in 2020 | Freeview (it does include Q4 2019).
The major changes at the retune, was a shift of the PSB channels, of the COMs only SDN had a tweak from 21+ to 21. So there is no "obvious" reason why your customers should have lost any COM multiplexes. Having said that, other changes elsewhere may have resulted in increased interference for some multiplexes in some locations.
I suggest you make use of the Freeview Detailed Coverage Checker, go to Freeview | All your favourite TV shows, all in one place and all for free scroll down a bit to "Check Freeview at my home" and put each customer's postcode and house number in the boxes (in turn) then on the new page scroll down until you get to "Detailed view" & click the button.
You'll then see the predicted reception of the various multiplexes and from which transmitters. Hovering over the channel number will show the transmission mode and power. The predicted reception may change next year as other transmitters complete their retunes. You'll see that from any entries in the tables.
Should I state the obvious, with some of the adverse weather of late, maybe they should be checking that their aerials are intact and still pointing correctly and downleads have not been damaged.
