Why these dates

Sow from two weeks before the last frost. Unlike a leaf lettuce you want this one to run up, so bolting weather is working in your favour.

Takes about -3C, the same as any lettuce, and the stem is no hardier than the leaf.

Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Celtuce are timed from 6 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Bexley.

The median frost-free season here is 219 days, against 70 to 90 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
