Hello my name is ***** ***** I will help you with this.
What is the full name of the Company please?
I have checked at Companies House (www.companies-house.gov.uk/info)
They are not a registered company and they have not been dissolved.
To be clear there is no company has is or has been called British Southern Ltd.
You should call Trading Standards and make a complaint.
If you paid by credit card for the install then your card issuer will be joint and severally liable under S.75 of the Consumer Credit Act 1974
Can I clarify anything for you about this today please?
I see. In that case its Green Energy Alternatives Limited
I can confirm that it WAS struck out, but it was restored by the Court on 25/5/16.
It has not been wound up, so it must have paid off creditors, it is still trading.
Does that clarify?
All the best.
