Fttc speed slower than previously

My son lives in a flat and has had Vodafone FTTC for three years, the last year out of contract. Looking at what Vodafone can offer currently is only a max speed of 25 mps, although he is paying for a speed higher than this. Vodafone tell me this is the max they can offer now .
I have been looking at other suppliers , BT say the guaranteed min speed is 30 mbs
Plusnet 21 mbs, same as Vodafone, EE also 23 to 25 mbs, however, Now and Sky are stating they can offer speeds higher than BT

I have asked others in his block of flats what speed they are getting, and one chap said he has Vodafone and is getting 42 mbs. Although the flat is on the 9th floor, someone on the 11th floor was getting a faster speed.

I am totally confused by all this, and we are not sure whether to move suppliers , although i am not convinced we will get a faster speed, or stick with Vodafone and save £10 a month

The postcode is M35EW

Any ideas, advice would be welcome

I have run a speedtest and via thinkbroadband and it states 41mbs, my son has run one via speedtest.net and got 25mbs

He really needs to look at what he is currently getting on FTTC as any switch to another provider is unlikely to increase the FTTC spread connection between his flat and the FTTC cabinet as that is mainly determined on the distance between those two points. Some here may also talk about congestion but you are then getting into the depths of the ISP network which may be too confusing.

What does: https://www.broadbandchecker.btwholesale.com/#/ADSL give for the number?

Observed speed 27.39 mbs

There have been alot of flats built very close to my sons in the past three years, putting more demand on the Blackfriars exchange in Salford.

and teh predicted ranges?

Vdsl range impacted 53.4 mbs high 37.3 low

If those flats come off the same green Openreach cabinet as your sons flat then it is technically possible that your sons broadband speed has slowed down because of them, its called crosstalk but Openreach will not and cannot really do anything about that sadly.

Yes i agree, but i wonder if we switch to BT it will be faster, Vodafone told me they were being restricted by Openreach but BT, EE and plusnet may be better. The latter are not offering anything faster than 25 mbs, but BT may be the best option.
Or Sky Which has its own LLU in the exchange!

Thanks for all the comments

Personally I don't believe he will be any better off as the sales person will only quote you the predicted speeds, Vodafone won't configure his broadband so its capped at 25Mbps, the distance between the flat and cabinet will restrict that, to say it a different way if the Openreach engineer tests your sons broadband directly at the green cab the engineer could get around 80Mbps.

Edit: added clarity
