Hi Matthew,
You can add a bounding box parameter to the WFS URL. For example:
https://environment.data.gov.uk/spatialdata/historic-landfill/wfs?bbox=100000,200000,150000,250000
where the bottom left corner of the bounding box is at coords 100000, 200000, and the top right is at 150000, 250000.
Regards,
Dan, DSP team
