Your household presents a study in divergent financial trajectories: while your personal savings rate sits comfortably at 29.7% on a £9,000 monthly income, the joint account is hemorrhaging at -79.4%, burning through £1,471 monthly despite £1,854 in combined deposits. The disparity suggests either discretionary spending concentrated in joint accounts or structural misalignment in how household expenses are divided—worth auditing, Sir. Your liquid position of £179,279 provides reasonable buffer against the £170,323 mortgage, though your investment stack (£131,089) remains modest relative to your pension holdings (£187,484) and earning potential; commission volatility (£38,145 peak versus £18,581 average) warrants deeper reserve planning. Systems nominal; income generation healthy, expense control fragmented.
