Well here's the ultimate expert; DG Monetary Policy at the BoE;
"Because they’ve depressed real incomes, that slowing in demand will to some degree follow from the very same rises in import costs that have pushed up headline inflation. Equally, if government support mitigates that effect, there is more at the margin for monetary policy to do. The MPC is likely to respond relatively promptly to news about fiscal policy. Whether official interest rates have to rise by quite as much as currently priced in financial markets remains to be seen."
The inflationary consequences of real shocks
This is all banker-speak, so let me translate;
If Downing St leaves well enough alone, the spike in import costs will suck money out of the economy by knobbling demand because people can't afford to pay for stuff anymore, thus counteracting inflation
over time.
If the Gov put in place measures to counteract this (e.g. capping energy costs, increasing pensions, etc. etc.) then less money will be sucked out of the economy, and the BoE
won't hesitate to increase rates. That's the warning to the Govt to not start messing about with basic economic realities.
(As the DG notes, govt intervention only displaces the loss; rather than hitting Joe Public in the pocket, it goes onto the national balance sheet).
It remains to be seen if the increases - if any - will be as bad as the markets are predicting. Which is banker-speak warning the markets not to go crazy pricing stupid increases into their yields because interest rates aren't going up that high.
As to the OP - I think with fair winds and good sailing, there's a good chance that the interest rates will stablise by Feb next year under a stable Sunak government. You may want to fix, as someone else said, just so you have some certainty, not forgetting to get any moves properly costed by your advisor.
To paraphrase Jack Reacher - it's always a 50/50. Either interest rates will go, up they won't. If you can make better odds than that, you should be a financial analyst.
FYI, I fixed for 5 years, 6 months ago, as I felt the ECB were on a long-term upwards trend (disclaimer, I am a central bank employee, but I don't work in Monetary Policy side of the Bank so all I know is what gets published on the website).
