But, for all the positivity from businesses, May's royal wedding is unlikely to bring much of a boost to the wider U.K. economy, according to an analyst.
Yael Selfin, chief economist at global accounting firm KPMG, poured scorn on an estimate by tourist board Visit Britain that the wedding could boost the U.K. economy by up to £2 billion ($2.7 billion).
Beset by volatile household spending, squeezes on real incomes and uncertainty over Brexit, royal nuptials aren't enough to provide a much-needed bump.
However, Brexit could inadvertently play a hand in boosting Britain's tourism industry for the anticipated weekend.
"The relatively weak pound will encourage tourists, especially from the U.S., to visit the U.K. and they are also likely to be bigger spenders in the period," Selfin said.
Royal weddings have traditionally held back growth, as was the case for the marriage of Prince William and Kate Middleton in April 2011.
According to the U.K.'s Office for National Statistics, year-on-year gross domestic product (GDP) growth dropped after that wedding. For that occasion, however, productivity took a hit as a public holiday gave Britons a day off work, alongside the warmest April weather in a century.
Whatever the weather on May 19, Britons are sure to tuck into a slice of cake either watching wall-to-wall royal coverage or, for those avoiding it, the small matter of the FA Cup final soccer match.
