6 is a very low number of channels. Assuming that is not just poetic licence, you should get some 33 TV channels, counting SD and HD separately, plus some radio ones also.
If you look at this list:-

Clicking on Mux at the top to sort by Mux, then if you are in a Freeview Light transmitter area, you only get channels from Muxes BBC A, BBC B and D3&4, and you don’t get any from ARQ A, ARQ B, or SDN.
But if you really only get 6 channels, then there is something seriously wrong with the feed to your TV, and you should contact your landlord to get this put right, or at least to let you put it right.
Even if you are getting the full complement of Freeview Light channels, all is not lost; you may be able to get to a more distant full Freeview transmitter by using an aerial suitable for DXing. Though I doubt the BT deal would run to one of those, and there may be restrictions about visible aerials where you live. House or flat, by the way? Things can be more complicated with flats, especially if it’s a communal aerial.
I would echo the advice to talk to a local aerial installer (really local, not just somebody on the internet pretending to be local, of which there are all too many 😢) to see what your options are.
Thank you all for your responses
Through the aerial socket on the wall I get 6 channels. I think the aerial is in the loft as I can't see it on the roof. We are not allowed to go into the loft and check because of health and safety reasons
Through an inside aerial I get alot of channels. Only problem is they constantly break up and keep getting the no signal notification. Have tried moving the aerial everywhere but with no success. Tried boosters etc nothing seems to work.
Not sure what to do as I'm in a contract for another year but I can't receive many channels which we watch
I'm in the SS7 area & I get everything loud & clear.
There's no harm in giving your postcode or atleast the first part that I've given.
No problem. I'm RM3
Got to be an aerial issue as in the Romford area you should get great reception from Crystal Palace.
I'd have a word with your landlord.
You said in a earlier post, "I think the aerial is in the loft as I can't see it on the roof."
How old is the property that you live in roughly?
I have heard that it was common, (maybe still is?), for house-builders to cable up with coax for TV points etc, but not actually fit an aerial. So it could be that in your loft you just have a cable with no aerial attached. If that is the case, it would certainly explain your problem.
"We are not allowed to go into the loft and check because of health and safety reasons"
Is it possible for you to stick your head up through the hatch just to look - without actually going in to the loft?
.
Landlord (which is a housing association) has actually put a lock on the loft so we have no access. It is actually ridiculous but nothing I can do.
I don’t know if this applies, but if you have an aerial that needs a masthead amplifier, and there is no mains in the loft, then it’s usual to have a small box that plugs in the mains, and sends the required power (12v or so) up the aerial cable.
When people don’t know what the box is for, they often disconnect it, or switch it off, which weakens the signal enormously.
It might be that this applies here; have a look for such a box in the aerial chain, and if there is one, and it’s switched off, switch it on again.

Some TV's and recorders can also do this - possibly 5 volts.
Our old BT Youview T2100 and T4000 had that facility ISTR, so the Pro Box might also be able to do it?
No DC on the aerial connections of my DTR-T4000, certainly.
And I’m not sure it would be a good idea to supply a DC voltage to anything in the aerial chain that wasn’t expecting it.
