Royal wedding: Preparations begin for William and Kate
Detailed preparations are under way for the royal wedding next spring or summer of Prince William and Kate Middleton.
Clarence House said meetings had been taking place, before the prince returns to his RAF squadron in Anglesey.
Miss Middleton said joining the Royal Family was "daunting" as the couple, both 28, announced their engagement at St James's Palace in London on Tuesday.
The news triggered congratulations from around the world and widespread news coverage in America and elsewhere.
The wedding will take place in London and the couple will then live in North Wales, where the prince, who is second in line to the throne, is serving with the RAF.
Speculation about the wedding venue has focused on Westminster Abbey, St Paul's Cathedral and the smaller Guards Chapel, where the 10th anniversary memorial service for Princess Diana took place.
'Excitement and anticipation'
A Clarence House spokesman said: "Prince William and Miss Middleton have spent the morning in meetings with household staff about the wedding.
"An announcement about the venue and date will be made in due course after other members of the Royal Family, Mr and Mrs Middleton and the government have been consulted."
In the Commons, Prime Minister David Cameron made a statement to MPs: "I'm sure the whole House will wish to join me in sending our warmest congratulations and best wishes to Prince William and Kate Middleton on their engagement.
"I'm sure everyone agrees this is wonderful news, we look forward to the wedding itself with excitement and anticipation."
BBC royal correspondent Nicholas Witchell said Buckingham Palace would be "very sensitive" to the economic climate when making its plans.
He said: "They will want to send a very definite signal that it is not on the lavish scale of the Charles and Diana wedding of 30 years ago, that it will be a royal wedding suitable and appropriate to the times."
Anti-monarchy group Republic said taxpayers should not have to pay any money towards the event as the wedding should be "private".
Speaking in a joint television interview, the prince revealed he had proposed while on holiday in Kenya in October.
He also said he gave her his mother Diana's engagement ring having carried it in a rucksack for three weeks.
Prince William said giving Kate the distinctive sapphire and diamond engagement ring was his way of keeping his mother close.
"It's my mother's engagement ring so I thought it was quite nice because obviously she's not going to be around to share any of the fun and excitement of it all - this was my way of keeping her close to it all," he said.
He said the timing was right for the pair but stressed that no-one was "trying to fill my mother's shoes".
His bride-to-be called the late princess "an inspirational woman" and said that joining the Royal Family was a "daunting prospect" but something she hoped to take in her stride.
They refused to say whether the prince proposed on one knee but Miss Middleton did say: "It was very romantic and very personal."
Prince William said: "You hear a lot of horror stories about proposing and things going horribly wrong - it went really, really well and I was really pleased she said yes."
He revealed he had asked Kate's father for her hand in marriage after he had asked her, and said the pair had found it difficult to keep their big news a secret.
"We've been talking about it for a long time so for us, it's a real relief and it's really nice to be able to tell everybody," he said.
The two said they were looking forward to having children but planned to take everything one step at a time.
The announcement ends months of speculation for the couple, who have been together for eight years after meeting while students at St Andrews University, Fife.
Miss Middleton, who is six months older than her fiance, is the eldest child of Michael and Carol Middleton, who run a mail-order business selling toys and games for children's parties.
The prince and Miss Middleton shared their university accommodation with friends and were revealed to be dating in 2005 where they were photographed on the Swiss ski slopes of Klosters.
They split briefly in 2007. During the television interviews, Miss Middleton touched upon their separation and said: "I think at the time I wasn't very happy about it, but actually it made me a stronger person, you find out things about yourself that maybe you hadn't realised."
