Works here with Plasma 5.14. And the Plasma dataengine which talks to the BBC service did not change the code since then. Any chance you experienced a potential temporary outage of the RSS feed from the BBC? (the dataengine uses the RSS feed, not the webpage)

Let's try to isolate where things might not work for you. Please install plasmaengineexplorer (part of plasma-sdk) and run it from the commandline. It will shod a window.

There select the "weather" engine

First test the searching:
source name "bbcukmet|validate|london"
Keep "Update on demand"
Click "Request Source" button.
As result a new item should appear in the bottom, "bbcukment|validate|london", which has one subitem where the Value is a string starting with "bbcukment|valid|multiple|" and then a list of places separated with | (best seen in the tooltip over the field).

Next test observation/forecast data fetching:
source name "bbcukmet|weather|london|2643743"
Keep "Update on demand"
Click "Request Source" button.
As result another new item should appear in the bottom, "bbcukmet|weather|london|2643743". whose subitems are observation and forecast data, e.g. "Temperature" and "Current Conditions".

Does that work for you?
