Do these thing wear out? I've noticed my servo giving less assisstance lately and am going to check the pipes tomorrow but was just curious incase the pipes are fine. I was thinking also that they're a sealed unit maybe and non servicable. Any pointers are welcome, cheers.

The brake booster or the vacuum pump off the cylinder head. Yes, both can wear out but typically they last a long time.

These vacuum pumps are called exhausters on a diesel.

Manifold vacuum

Most diesel engines now have a separate vacuum pump ("exhauster") fitted to provide vacuum at all times, at all engine speeds.

On the side of the exhauster/vacuum pump (lol) is a bit that the pipe from the servo connects to and it seems to be loose and wobbly. I expect that might be the issue. I don't know how it's fitted yet but will try and have a closer look tomorrow.

If its a push on connecter then it may appear loose. You could always put some soapy bubbles around it and start it up and see if the bubbles get sucked in.

I'll try that, it's the metal part that the hose clips onto. Might be time for some chemical metal.
