Bit of a delay, but now double checked, and found marking on black poly pipe - looks like "TELCON BS 1972 ...CLASS D". Old Alkathene pipe?! Must be the 1/2 inch OD, which from what I have found is just 14.1 mm ID.Problem might be with the poly pipe internal diameter, if you can measure the OD then ID can be determined, a pressure gauge reading, even static, taken anywhere would be a help as well, also estimated distance from mains stopcock to your house.
Looks like that may be the only answer.If you want more flow rate, you need to get more from the street.
Replace supply pipe with 25mm (ID or OD?) ? AND put in accumulator (had not thought of that) ?Even with a new supply the water might drop eg won’t stay at a solid 16lpm as the water services in the area might not be upto all capacity etc
Tbh new 25mm water service and install an accumulator
