When plumber calls out, you'll see why its now part of regs to have isolation points fitted before both ballcock. It can be tricky to turn off main water supply. Ball valves fitted just before ballcock are a god send, if you had trouble with overflow, overflowing all over attic, you probably wouldn't be able to turn off mains supply. If valves were fitted @ ballcock, you'd have no problem turning off water to ballcock.
Tanks must be fitted with correct lid, the tank you have would of been sold with a matching lid, no idea why plumbers don't put them on. Its part of building regs, all tanks must have lids. Water in storage tank is for washing, showering brushing teeth, very easy for bugs, rats, mice etc to make way into storage tank. Not nice when you find dead body's of mice, bugs, rats, birds etc floating around in water, then have to tell homeowner all about it.
Plastic lid must be fitted, wood lids, insulation lids etc all fall apart over time due to condensation.
