Well I work for probably the most bike-friendly large company. Happy to put you in touch with our coordinator.
But… Lockers and storage for shoes are a must. Lockers should hold a suit and two shirts as a minimum. We have a regular locker usage survey, because of the high demand.
Laundered fresh towels.
Decent shower gel.
Folding ironing board. Ours is never folded away and the irons break from being dropped.
Hair driers for hair and gloves, of course.
Benches to sit on to change and place clothes when changing
Hanging space for cycle kit. It doesn’t dry in a locker.
Now the value added: we have a cupboard with emergency spares to get home. We have a bike shop on site and free servicing and labour.
We are rewarded with one pound per day to spend in said shop or Evans.
W have a very generous bike to work scheme.
But the nice white towels fresh daily, unlimited Dove gel and somewhere for my suit are what matters!
