Under the heading Requirements for Work Stations (Reg 3. and schedule):
24 Regulation 3 requires workstations to meet the requirements of the Schedule, (subject to the proviso outlined below), which sets out minimum requirements for the display screen, keyboard, desk, chair, work environment (including working space, lighting, reflection and glare, noise, heat and humidity), task requirements and software. Requirements are set out in fairly general terms, eg "The seat shall be adjustable in height". The Schedule does not contain technical detail.
Paragraph 32 states that anti-glare filters must be provided by workplaces which use DSE (display screen equipment) which are capable of projecting glare.

There is also a similar European Union directive, however, that does not apply to laptops if they are used only infrequently (annex 1b): https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:01...
So while the rest of the world might differ, in the EU non-glare screens are usually required if you intend to sell to business customers.
