On 1 October 2013, the Property Misdescriptions Act 1991 (PMA), which previously made it a criminal offence for estate agents to make false or misleading statements about properties being offered for sale, was repealed. The government has taken this step in order to reduce duplicate legislation because there are now two other pieces of legislation which regulate estate agents and other businesses involved in property sales and lettings: the Consumer Protection from Unfair Trading Regulations 2008 (CPRs) and the Business Protection from Misleading Marketing Regulations 2008 (BPRs)..
Why one is entitled unfair trading regulations and the other is misleading marketing regulations, I have no idea but it doesn’t affect the substance.
Apart from the above, you also have a claim for the landlord’s breach of section 11 of the Landlord & Tenant Act for failing to keep the property and repair and of course breach of the covenant to do the same in the tenancy agreement.
You can of course make a complaint also to the Environmental Health Department at the local authority who, in the damp is bad enough can declare the property unfit for human habitation and stop the landlord renting it out and compel him to do the repairs. Worth contacting.
Thank you for letting me assist you with your legal question. I am glad that I was able to help.
I am not certain whether that answers the question for you or not, but I am happy to answer any specific points arising from this.
It will be my pleasure to help you again either further with this or any future questions you have
