The claim, plainly

The UK had gone 47 days without needing to run any coal power plants before June 2023.

Assessment

Emma Woollacott stated that the UK had gone 47 days without coal power before June 2023. Grid data and reporting from June 12–13, 2023 (when National Grid ESO dispatched the Ratcliffe-on-Soar coal power station due to high air-conditioning demand and low wind generation) confirm that Great Britain had operated without coal-fired electricity for 46 consecutive days, beginning in late April 2023. Because the stated figure of 47 days differs by only one day from the actual 46-day streak (well within a standard margin for offhand numerical recall), the claim is rated partially true.

National Grid ESO dispatched Uniper's Ratcliffe-on-Soar coal plant on June 12, 2023, ending the coal-free run.
Major news and grid tracking reports (including The Guardian, ITV News, City A.M., and The Daily Telegraph) documented that the streak lasted 46 consecutive days prior to the June 12, 2023 dispatch.

Woollacott: Traditional weather simulations are constrained to one-kilometer resolution

“To do this properly, thoroughly it means an awful lot of computing power is required, and an awful lot of time, so the resolution can't be particularly high, we're looking at about a kilometre square, and they can't be particularly fast, because there's a huge…”
