No — this is principal and interest only. Council tax and buildings insurance are paid separately on top. UK mortgages don't charge separate mortgage insurance — lenders price risk into the rate, so smaller deposits mean higher rates.
Over the full 25-year term at 5.10%, total interest on a £450,000 mortgage is roughly £347,082. Overpaying reduces this substantially.
