The flow to my bath has dwindled over the years, it's a conventional

benefit in dosing the cold water tank with sulphamic acid and then
recirculating through the bath tap connection with a pump?

A tub of fernox DS3 will make enough gallons to fill the tank and the
cistern, so yup recirculating with a pump for a few hours should do the
trick. Keep the immersion on for better performance (but don't let the
cistern get too hot if its plastic - they can go droopy if not well
supported)
