There is no requirement for U.K. passport holders to apply for a visa prior to entry into the Maldives.
A visa is required for registration but you will be asked to fill out this form during your flight for production at Male airport. There is no cost for this but there is a Maldivian departure tax equivalent to approx $25. This is collected locally on departure and there is no facility to pre pay this tax.
With regard to Health you are visiting a tropical climate and although the country is very health and hygiene conscious you should always seek the most up to date information from your G.P. or Pharmacist at the earliest opportunity.
