While I agree relative humidity has its flaws, this isn't true. Assuming OP is in the northern hemisphere, temperature is indeed dropping. However, cold air stores less water, so the relative humidity for the same amount of water would go up, not down.

If OP is in the southern hemisphere, then I would question if what they are plotting is actually an improvement due to the remedial works or just a rise in temperature.

I don't know how basements are designed in the UK, but around me, surrounding a room with earth keeps the temperature from changing much, regardless of outdoor temp. At 6 feet deep you're looking at less than 4 degrees change at any point of the year, even in harsh winter climates like Minnesota.

Can confirm temperature has remained consistent day to day - the space is heated with the thermostat to maintain target temps to the same schedule. If more useful for comparison the dew point has been dropping and VPD increasing in line with the above which would indicate an actual decline in moisture.
