Wedding venues have attacked the government after they were left confused about lockdown rules.
An industry group claimed as many as 7,000 weddings could have to be postponed or cancelled after restrictions were clarified.
England's roadmap says weddings - currently limited to six people - can resume with up to 15 people from April 12 at the earliest.
It also says wedding receptions can resume with up to 15 people from the same date.
However, the February 22 roadmap also stated that these events could only happen "in premises that are permitted to open".
In practice that only means places of worship, public buildings or outdoors - because indoor hospitality venues must stay shut until at least May 17.

Despite the disclaimer on page 34 of the roadmap, the UK Weddings Taskforce now says some of the 71% of venues not allowed to open had already started taking bookings for late April and early May.
The group said the venues were left confused because the disclaimer was not on widely-shared graphics and summaries of the roadmap.
The estimate of 7,000 cancelled weddings is a rough estimate from the group, after it claimed bookings for April 12 to May 17 were already around a third of their normal rate.
The Taskforce - which was set up with the backing of government and describes itself as the "the single unified voice" for the £14.7bn industry - said the problems could have been avoided if it had been given full, detailed guidance specific to the industry.
Spokeswoman Sarah Haywood fumed: "A couple could technically get married in a zoo, but not in a Covid-safe, purpose-built wedding venue.”
She said venues had only got to the answer "by analysing the small print" after repeatedly asking for more detail.
She added: "The £14.7bn wedding sector can reasonably expect Government’s own messaging to be clear and unambiguous. It is neither.
"After a year of uncertainty for businesses, their employees and over half a million people whose weddings have been on hold, this is yet another major blow.
"It will cost the industry - already on its knees - millions of pounds, lead to the loss of more jobs and leave an estimated 7,000 couples without a wedding."
Most indoor wedding venues in England can reopen from May 17 at the earliest, at the same time as pubs and hotels generally.
At this point, indoor gatherings will be limited to six people or two households, though wedding ceremonies and receptions will be allowed up to 30 people.
The roadmap does not make explicit whether this allowance of 30 people will apply to both indoor and outdoor venues.
A Downing Street spokesman confirmed: “Events can take place in venues that are permitted to open at each stage.
“From April 12 at the earliest, because outdoors is safer than indoors, wedding receptions must take place in outdoor venues.”
Asked to clarify that receptions must be outdoors from April 12, he replied: "Correct.”
“The roadmap sets out quite clearly which venues are permitted to open at each step of the roadmap.”
