In reply to Andrew Wilson:

No, it isn't out there.
In fact the only relevant mention on the matter from HSE is that helmets "should fit the person wearing it and be worn properly", and that it "can it be adjusted to fit the wearer correctly"
In their published guidelines they state:
"A properly fitting safety helmet should have the right shell
size for the wearer and an easily adjustable headband,
nape and chin strap.
The range of size adjustments
should be large enough to accommodate thermal liners
used in cold weather."
Nothing about not wearing a hat provided the helmet adjustments are large enough to accomodate it underneath.
If you have concerns about the helmet falling off the employee's head's, then the guidance says "use an adjustable chinstrap, if fitted, to make sure the helmet does not fall off". Since it's the employers responsibility to provide suitable head protection, then if you deem the helmet coming off as a risk you should provide a suitable helmet with chin straps. If you have had claims that went through from people whose helmet fell off and then banged the head, the same claim would go through hatless on the grounds 'the helmet didn't fit my big head/small head/pointy head/squat head/baldness/mullet/tupee/hair style/whatever properly'.
The only way you can save your arse from that to legally comply with the 2002 PPE regulations which states that:
"1.3.1 PPE must be so designed and manufactured as to facilitate correct positioning on the user and to remain in place for the foreseeable period of use, bearing in mind ambient factors, movements to be made and postures to be adopted. For this purpose, it must be possible to optimise PPE adaptation to user morphology by all appropriate means, such as adequate adjustment and attachment systems or the provision of an adequate size range. "
they also say that
"Chin straps should be provided and used if
a job involves work in windy conditions, especially at
height, or repeated bending or constantly looking upwards"
and that it "should fit the person wearing it and be worn properly", is as noted by Gustavo above by providing head fittings of helmets to each individual or providing chin straps. Anything else is rules for the sake of rules.
Your role is to ensure PPE is adequate. Putting a hat ban in place does not ensure PPE is adequate, and it disallows the use of perfectly adequate PPE, which is something that may make some people sitting in an office feel they earned their wage while making the lifes of the workers on the ground more miserable when having to work in the cold and rain in the winter without some very basic cold weather protection.
It's simplistic hard and fast rules which are justified by several reasons that never really cut it. The helmet may fall off? Provide helmets with chin straps. The helmet don't sit properly in the head? Provide larger sizes and/or helmets with a wider size range. "I can't tell if you are listening to music through headphones with a hat on (Yes, i was given that as a reason)", Well, cry me a river. Even sometimes the claim that "HSE don't permit the use of hats under the helmets"...
To the OP. So far as you ensure the helmets get adjusted and fitted properly following the manufacturer's instructions your arse is covered. So snug, centered and level as in the drawings on the instructions that come with the helmet.
