So the hub is in the hall. I get 80% signal in the lounge right next to it, 50% in the conservatory, but 100% upstairs?!

What's the best settings to improve the Wi-Fi please as this appears odd to me.

Move the hub to a more central location.

There is likely only one parameter you can change, the WiFi channel being used.

What is probably causing the signal differences is a combination of building construction and interference. Different materials used in the walls and ceilings will attenuate the signal in different ways and the more walls etc the signal has to go through the lower the resulting signal will be.

So it is not in the least bit surprising or odd that you get wildly different signal levels in different rooms. Not much you can do about attenuation through walls and ceilings other than do a bit of DIY with a sledgehammer to remove the obstruction Or more practically move the HomeHub to improve signal transmission in certain areas but perhaps at the expense of signal in other areas. In some cases it doesn't need much movement to make a big difference.

If interference, often from neighbouring WiFi networks, is an issue then changing channel might help, if there is a clearer one to switch to of course.

I was looking at getting a better router but it's hard to decide which one.

There is no guarantee that a "better" router will give a better wifi signal than you have now especially if you place it in the same location. Before spending more money on a router use cables, which are much cheaper, to relocate the BT router, generally speaking the higher it is the better, the signal will usually pass through floorboads easier than solid walls. Take a look at the BT community forums, there are lots of posts on the subject.

For what it's worth I have been using the HH5 on Infinity 1 for some time without any issues. The three main tips are:
Turn off smart set up.
Separate the 2.4 and 5ghz bands giving them separate SSID's.
If you are in area where other wifi signals are seen then try a different wifi channel.

If you have a spare electrical socket in the conservatory why not consider getting a Wi-Fi extender. It will pick up the radio signal from the hub and simply repeat it. I use a BT Dual Band Extender 600 with my Hub 5

As already mentioned a new router may be no better and could be worse than your current router - Wi-Fi reception is a dark art!!!

If you use Windows (especially on a laptop) consider downloading Insidder 3 - this allows you to analyse both your Wi-Fi signal and any others being received. On a laptop you can walk round your house looking for the best reception spots (using the "score" in the top right hand corner).

Current versions of the software now cost but you can get the program for other systems.

Clicking on the "Windows" option under Download Options should give the program without any crapware.

That's very useful software Brian. I just checked out my local networks with it and all were on channels 1 or 11, so I've now forced my HH5 to use channel 6. Should be interesting to see if there's any improvement.
