The commonly accepted number for the Red Snow (US Mk.28 adapted) warhead of Yellow Sun Mk.2 and Blue Steel is 0.85MT. The precise answer to your question is US Mk.15/39 in 90 Sqdn Valiant, Honington, 12/58-5/9/61, at 1.69MT.

Only Trident warheads are left in the inventory. They have an approximate yield of about 100kt each.

One of the old “Grapple” tests I believe had a yield of about 3 megatons but the largest weapon yield wise in actual British service was the Red Snow weapon. It had a yield of approximately 1 megaton.
