Baliffs are threatening to force entry over a Ten pounds fine which they have raised to 310 pounds. On Friday morning I am scared to death and at my wits end please advice me of my legal rights. Thank you

They CANNOT force entry, but if you leave anything open they can come in.
So more details would be helpful.
Where was this £10 fine from and has it actually been to court?
Have they explained where the extra costs have come from?
Is this the first time you have communicated with them?

Well, if they have a court order giving them the right to enter and you refuse to open, I would say they can force their way in, if the court order they have gives them that permission.
So open the door and let them in and they will not have to force their way in will they?

In the UK a bailiff CANNOT simply force entry for money related offences.
There's very few times this is allowed and they MUST be accompanied by uniformed police.

Ok, confused, a balliff is in uniform in the US, and they are the ones that enforce civil court orders. Evictions ( which require forced entry often)

But then would the balliff simply just return with a police officer if entry is to be made, If they did not have one with them at the time, when they return they would have one ?

Some UK bailiff companies over state their powers to gain entry, especially when debts or fines are involved. The fear of these activities is enough to force people to open up and let them in.

I would say they out right LIE, but that would be stretching things a little, allegedly..

There are other types of bailiff in the UK, but they are normally refereed to as Enforcement Officers and have very different powers available to them.
