Would a Processor Server help where High Court Bailiffs have failed?

Hi all, I read on this site that some landlords use Process Servers. Can someone please explain how that works?

I have two large outstanding debts from previous tenants who have long since been re-housed and according to their internet profiles they are both enjoying the life of riley one way or another. One is an ‘influencer’ so is all over social media. I know where both of them live – neither are no longer in ’emergency’ or ‘temporary’ accommodation.

Both debts were escalated up to High Court Enforcement – however, due to the notification of bailiff visits now being a legal requirement – these two just hide virtually in plain sight at the time of any planned visit. Bailiffs say they’re convinced that someone is at home when they’ve called. Neither tenant opens the door.

There is no point in pursuing that route any further so I’m thinking along the lines of pursuing an assessment of their financial circumstances. Is that something that could be done with papers issued by a process server? If so, is there direct access to process servers – or do they only take work from solicitors?

Thanks in advance for any responses received.
