You may be able to claim Universal Credit if you are unemployed or on a low income, subject to rules about your age, savings, housing and household circumstances. You normally apply online through the official GOV.UK website and will need to attend an appointment and agree a claimant commitment. Your payment is assessed on your circumstances and any earnings or other income, so the amount and eligibility can vary. Check GOV.UK for the current rules and use a benefits calculator if you want an initial estimate.
