Sharp practice in the London rental market

[user1486204288]

My son lives in a property in south London owned by a slum landlord. It has recently come to light that he and 5 other tenants have been living there in an electrical death trap for 3 years. (They have always had to pay her in cash). They now also have to live there while builders are there from 6.30 in the morning til 4.30 (including Saturdays) while they renovate the place. Asbestos has also been removed without any precautions being taken nor warning.
Obviously this is her way of getting rid of these tenants so she can triple the rent or sell the house.
What are their rights?

Their rights in relation to what? The asbestos removal is covered by health and safety regs.

Their tenancy rights re. Underhand Strategy to get rid of them.

Are they still in their assured tenancy period - what was the contract they signed, has it moved on to periodic? Because if they are out of their assured tenancy period (often just the first six months and then it rolls on to a periodic, unless they have renewed it over the years) then she could just give them notice anyway.

If it is a death trap then it needs fixing.

Talk or look at either Shelter or the Citizens Advice website. Rights clearly documented there.
