As you haven't given a full postcode, we can't check your predicted reception and there's always the possibility that weather conditions might affect it if you are in a marginal area.
There are currently no reported faults for Sandy Heath and it's not currently listed for Planned Engineering.
Check that your aerial looks intact and is still pointing in the correct direction and that the downlead is secure and not flapping in the wind. Check all your coax connections behind the TV etc.
Have you altered/changed anything about with your equipment recently? Do you have any distribution amp/splitter etc.?
You are never advised to retune when you have no signal or badly pixellated pictures as this usually just clears the correct tuning. So whilst signal is steady, try a manual retune on Sandy Heath's UHF channels to ensure you are correctly tuned.
Post back with a full postcode if you are still having problems.

Hater4life: Rather than assuming that the transmitter is at fault (if it was hundreds of people would be complaining) have you done any investigation into whether something at your end might be causing whatever issue you are having? Simple things like checking and unplugging/reconnecting cables can often help track down the cause. Another thing to check is whether a new or upgraded 4G/5G mast might be causing interference - put your postcode into the checker on https://restoretv.uk/ and they'll send you a free filter if interference is predicted.
If none of that helps, let us know your full postcode so that we can see the predicted signal strength at your location.

If you provide a full postcode, we might be able to offer some constructive advice or comment.
However, suggest you read the post about Planned Engineering just before yours.

Apart from which, current weather conditions currently accompanying the high pressure will not be helping, for a simplistic explanation, see -

This tends to happen more in summer, but can occur at other times.

You are about 20km from Sandy Heath, compass bearing 150 degrees (that's almost SSE) and the rods (or squashed Xs) should be horizontal.
Considering the transmitter powers used at Sandy (182/170kw PSB/COM multiplexes) you should have very good reception, and a medium gain aerial used externally would probably be adequate if good quality double screened coax is used feeding just one set (and not an excessive cable run!).
I'd think about something like 28 to 36 element K Group Log periodic types (yes grouped log-periodics are now made!).
Eg. something like the Blake BLA-LP28K if you have an unobstructed line-of-sight view, but check what your neighbours are using or get specialist advice from an installer that knows your area well.
(Details from Blake's website https://www.blake-uk.com/…tml)
Whilst Group T/Wideband aerials would do, they give no protection to mobile interference if you should get a mast near you and you'd probably need to add a filter.
