Deposit Disputes
When your tenancy ends, your landlord must return your deposit within 10 days of you both agreeing how much you get back. If they refuse or try to deduct unfairly, use the deposit scheme's free dispute resolution service. "Fair wear and tear" is NOT deductible — your landlord cannot charge you for normal ageing of carpets, paintwork, or appliances.
Rent Increases
During a fixed-term tenancy, your landlord cannot increase rent unless there's a specific clause allowing it. On a periodic tenancy, they must use a Section 13 notice giving proper notice. You can challenge excessive increases via the First-tier Tribunal (free to apply).
