I'm not here to defend Starmer at all but I think you've been hoodwinked by the Tory party line here. Inflation has been stabilised by a combination of the world's central banks putting up interest rates (nothing to do with Sunak or Hunt), the supply side shocks after the pandemic easing (for example the Chinese rolling blackouts and factory shutdowns have stopped and shipping is more or less back to normal I think), and the price of gas going down again as the profiteering off the war in Ukraine settles down. And wholesale energy costs are back to roughly pre-war levels now, yet your bills aren't, because the government have no interest in making the energy market more affordable and as such are happily damaging the economy. In terms of taxes, they have gone up loads in the last few years, so even if they could afford to put them down, which I doubt given the anaemic growth in the economy and massive national debt, you'd still be worse off than you were before they came in.
So no, Sunak and Hunt don't have ideas, even less so than Starmer and his vapid Chancellor.
