You can find free guidance on renting, deposits, repairs, eviction and discrimination from Citizens Advice, Shelter and the official GOV.UK housing pages. Housing rules differ across England, Scotland, Wales and Northern Ireland, so check the guidance for where you live and contact your local council if your landlord may be breaking the rules. Your local Citizens Advice service may explain your options and help you find specialist support. If you need to take legal action, consider speaking to a solicitor regulated by the SRA and ask whether legal aid is available.
