I have made a connection to this WFS layer through the QGIS data source manager:

QGIS Data source manager

The layer takes a very long time to load, but when it does it appears flipped and rotated:

WFS SSSI Layer flipped/rotated incorrectly

I think this has something to do with coordinate reversal, maybe the order in which QGIS is expecting the X and Y fields?

Can anyone suggest a way for me to correct this for a WFS layer? I'm fairly comfortable with the PyQGIS API.

    So what kind of information/parameters/URL etc. exactly did you enter?

    Check the flip axis order box on the connection page, or use a different version of wfs standard

Ian Turton commented with the answer (thank you). I also found it in this previous question.

I edited the WFS connection and checked the "Invert axis orientation" box. It should be noted that this caused the layer to flag for "repair data source" until I saved the project, closed and re-opened it. I've also notified the data provider that it is returning with incorrect axis order for this CRS (OSGB36 / British National Grid).
