Just because they have registered a limited company doesn’t mean that they can trade as that limited company. It means simply that the limited company name was available.
They have clearly decided that you have a good name and that they would grab it to try to live off the back of yours.
They are “passing off” by choosing a name which is so close to yours.
I suggest you get a solicitor to write to them to tell them to either change their company name and their trading style failing which you will make an emergency application to court for an injunction (and legal costs) to prevent them continuing to use the name and you will also be seeking damages and compensation from them in respect of any loss of business this causes you.
They would take more notice if that letter comes from a solicitor than if it comes from you.
Can I clarify anything for you?
Please rate the service positive. It doesn’t cost you anything but helps me greatly.
We can still exchange emails. Best wishes. FES.
With regard to the website, you need to put a claim into Nominet.
You can have the domain transferred into your name because they have no right to it if they are just trying to live off the back of your business and they only registered the domain after you were trading.
Domain squatting, is not illegal and they are able to do it.
If they had the name registered for a long time and you started trading sometime afterwards, then they are allowed to keep the name (but not use it) and they could sell it to you even at an inflated price.
However, what they can’t do is see someone else’s name who is already trading and then go and register domains in that name to prevent the one that is already trading getting it.
You need to tell the firm (solicitor will tell them) that unless they agree to transfer that domain to you, you will file a complaint with Nominet.
It is some years since I dealt with one of these claims to Nominet but I do know there is quite a substantial fee (it was about £600) for submitting the claim.
If you ask forme personally, “For FES only”, you will then be dealing with me because I obviously know the background.
