Until now, weddings and civil partnership ceremonies have only been allowed to take place in England in exceptional circumstances and receptions have been banned.
According to the government's plan for weddings, the next stage - no earlier than 12 April - will see ceremonies and receptions allowed for up to 15 people.
However, they will only be possible if they meet certain rules - for example ceremonies must be held in Covid-secure venues that are allowed to open, and receptions can only be in the form of a sit down meal or in outdoor venues and cannot take place in people's private gardens or public outdoor spaces.
The numbers are then set to rise to 30 people from the next step, no earlier than 17 May, and then the government's plan is to lift all restrictions in the final step which could be 21 June at the earliest.
In Scotland, wedding ceremonies and receptions for up to 50 people can resume from 26 April, but no alcohol will be allowed at receptions.
Currently receptions are prohibited, while wedding ceremonies and civil partnership registrations are allowed a maximum capacity of 5 people.
In Wales, licensed visitor attractions and hotels can open to hold wedding ceremonies. The maximum number of attendees is determined by the building's capacity.
And in Northern Ireland, up to 25 people can attend a ceremony, although events with more than 15 people require a risk assessment. Face masks must be worn by guests
