Hi .  You should not be grouping them.  You need to add the Fives as surrounds to the Beam.

You will probably then want to choose FULL audio rather than AMBIENT for music listening, in the Beam’s settings.

Note: my response assumes that the Fives are being used in the same physical room as the Beam.

When grouped with the Beam the Fives will be slightly delayed when playing TV audio. They’ll play in sync for other, music sources. 

You could always bond the Fives with the Beam as surround speakers. They’d then always stay in sync.

How does one set them up as surround speakers?  When I try it only gives me the option to pair with my ones. 

Separate the stereo pair:

Then add as surrounds:

Sonos has a bunch of tricky words.

Pair - Hook two very similar speakers together in a stereo pair.

Bond - Hook an AV Sonos to surrounds and a Sub, or a speaker or stereo pair to a Sub.

Group - Connect Rooms together to play audio in sync, or TV sound with a slight delay.

Pair and Bond make a single Sonos room out of all the included speakers.

Grouping connects the Sonos Rooms together.

Thanks, only trouble now is that it's saying if I set them up as surround speakers I can't use the line in which I have hooked up to play my records

That is correct.  When connected as surrounds the speakers are just “slaves” of the Beam.  

Let’s take a step back here.  Do you want multichannel  surround sound for your TV watching?  Where are the Fives positioned in relation to the Beam?  Why do you want the Fives to play exactly the same audio as the Beam when you are watching TV?
