My mortgage deal is ending, how do I avoid a high rate?

Our two-year fixed mortgage rate is up in August and we have roughly £340,000 left on the loan. I was hoping interest rates would have come down by now and I am reluctant to lock in for another two years when they are still this high. Is it best to revert onto our lender’s standard variable rate or go onto a tracker? Do some lenders offer one-year deals?
