Only if it’s a car accident
I'm not sure that's true. People who get injuries at places like Theme Parks can sometimes go through the Small Claims Court. Whether they win can be a different matter.
Someone upthread mentioned using a No Win, No Fee Solicitor. I would advise against this.
If you don't want to do it in your own through the Government websitee then talk to your local CAB or see if there is a Clock Servicee near to you.
I would read the government guide all the way through as lots of people don't realise some basic things, like you may have to pay a hearing fee as well as the initial fee of it goes to trial.
Also, make sure you get the name of the defendant absolutely right or you may have to pay to change it.
If it's a company you can check on companies house exactly what the name is. If it's an individual but trading you'll probably need the format John Smith T/A Plymouth Tiling.
Also remember that if they don't pay, and there's no guarantee that they will, any enforcement you issue will have another Court Fee and again, it's not guaranteed that they will pay.
