Freeview have just announce the final 700MHz Clearance dates and the remaining change for Moel-y-Parc will be on the 12th August.
COM4/SDN multiplex is moving from C51 to C33.
This means that the final channels for Moel-y-Parc will be
C45, C39+, C42, C33, C36, C48, C55, and C27 that's in the order PSBs1-3, COMs4-7, & Local
Which of those multiplexes you can receive will (as always) depend upon your location, those that you currently receive should not change, there are no power changes and no further aerial changes should be required.
(Note - COM8 was closed by Arqiva for commercial reasons on the 22nd June, see Rebuilding Freeview High Definition from 2019 onwards | free and easy ).

Just to add to the above, Freeview have just announced the Final 700MHz Clearance dates to be the 12th and 19th August.
Most of the remaining Granada region (notably including Winter Hill) on the 12th August, Douglas & relays on the 19th August.
Wales, Moel-y-Parc on the 12th August.
Border region - Some Caldbeck relays on the 12th August, Kendal transmitter group on the 19th August.

Just to add to the above, if you had problems receiving the COM5/ArqA multiplex when it moved from C52 to C36, the COM7 multiplex when it moved from C32 to C55, and the Local multiplex when it moved from C56 to C27 all on the 27th February 2019, then you possibly needed an aerial upgrade if you haven't already got a Group T/Wideband aerial. After the final changes, if you are not predicted to receive the temporary COM7 HD multiplex on C55, or not interested in doing so, then a Group K aerial may be better if you are generally in a weaker signal area.

Major update since my last post here, Freeview have just announced the dates for the final 700MHz Clearance events. It will be the 12th August for Winter Hill and some relays (and some remaining Granada region transmitters and relays). Douglas is on the 19th August.
So as previously posted the final channels for Winter Hill will be -
C32, C34, C35, C29, C31, C37, C55, C24, C21, C40, C27 that's in the order
PSBs1-3, COMs4-7, Manchester Local, Liverpool local, Preston Local, Manchester GI multiplex.
(There is a query on the channel for the Liverpool local mux as the clearance document says C24 -same as Manchester so unlikely) whereas other documents all say C21 as at present).
NOTE: IF you are not currently getting good/any reception of the BBC SD main channels on UHF C32 in their correct LCNs 1,2,& etc and only getting them in LCNs 751 & seq. on UHF C50, then the C50 simulcast will cease on the 12th August, and if you haven't arranged for the Free In-Home Support to have your aerial replaced you should do so A.S.A.P. by ringing Freeview on 0808-100-0288.

Freeview have just announced that the expected 700MHz Clearance retune event will be on the 19th August.
PSBs1-3 move UHF channels to C41, C44 & C47.
If you have an old C/D group aerial and live in a very weak signal location, you may need to change it for a Group B aerial.

According to the Freeview Detailed Coverage Checker you are 68km from Crystal Palace, 24km from Hannington, 36km from Oxford (and 64km from the quite low powered Reigate transmitter - no COM7). Those 3 main transmitters are horizontal polarisation whereas Reigate is vertical polarisation.
It will of course depend on which way your aerial is pointing (and what it is) as to what you are actually picking up off the main beam and maybe some side-lobes/rear of aerial. From you, bearings are as follows -
Crystal Palace is 94 degrees, that's fractionally S of due E, Hannington is 214 degrees, that's slightly S of SW, Oxford is 344 degrees, that's slightly N of NNW. (Reigate is 112 degrees, ~ESE).
Neither the Freeview Detailed Coverage Checker nor the BBC predictor show any reception from Oxford (presumably terrain, but that doesn't mean you won't get any signal!), other than that predicted reception of the 6 main muxes does vary slightly across your postcode, with overall Crystal Palace & Hannington being similar BUT no predicted reception of COM7 (C55) from Crystal Palace, but there is from Hannington which can be Good to Variable.
Note Hannington and Oxford supposedly transmit the same ITV Meridian Local news, whereas the BBC Local news should be Oxford from the Oxford transmitter and South Today from Hannington.
In the order PSBs1-3, COMs4-7, Local multiplexes, the UHF channels are as follows
Crystal Palace C23, C26, C30, C25, C22, C28, C55, C35 (London Local mux)
Hannington C45, C42, C39, C40, C43, C46, C55, C34 (Reading Local Mux)
Oxford C41, C44, C47, C29, C37, C31, C55, C22 (Oxford Local mux)
Oxford COM7 is lower power than Hannington. Crystal Palace being the highest (but no predicted reception!)
Note, Arqiva closed COM8 in June for Commercial reasons, see Rebuilding Freeview High Definition from 2019 onwards | free and easy
I'd think that you are most likely getting COM7 C55 from Hannington, but I repeat it depends on what your aerial is and which way it's pointing.

Robert Hellier:
Had meant to include a remark that reception can of course be affected by some weather conditions. There is predictions at the weekend for some quite strong "Tropospheric Ducting" (see Effect of tropospheric ducting on Freeview | RTIS and How does good weather affect my television? | RTIS ). It's not just reflections of signals, they can travel along what is like a tunnel in a layer of atmosphere.
So there could well be some disruption to reception coming up.

As per previous post, really need a full postcode to double check, but I can't find any faults currently listed by Freeview or the BBC. Have your signals returned?
