£50,000 a day: how London's richest residents spend their money

The average British household spends £676.60 a week — the latest figure from the Office for National Statistics, covering the year to March 2025. A wealthy Mayfair resident, by estate agent Wetherell's count, puts up to £50,000 a day into London's economy. That is a gap of more than 500 times.

How much do London's richest residents spend?

Wetherell, an agency that works only in Mayfair, puts it this way: a millionaire living in London all year contributes up to £50,000 a day to the city's economy. Someone who visits contributes around £4.5 million for every 90 days spent in London. Individual days, the same research says, can reach £500,000.

£4.5 million over three months is close to 128 years of an average British household's spending. A single £50,000 day is more than 500 days of one — a year and five months.

Where does the money actually go?

The breakdown for a typical super-prime Mayfair household, as cited by Wetherell:

Retail — £664,000 a year. Six domestic staff, including nannies, chefs and chauffeurs — £350,000 in salaries. A lawyer and in-house publicists — up to £300,000 a year. Personal security — about £150,000. Keeping fit, much of it personal trainers — £117,000. Entertaining at home — £137,000 a year, with the household also eating out about four times a week. School fees and tutoring — £100,000 a year per household. Medical and cosmetic procedures — £100,000 a year. Fast cars and the latest gadgets — £125,000 a year. Grooming — £19,000 a year. Interiors — up to £2.7 million, including £750,000 on artwork.

For comparison, an average British household spends £35,183 a year in total. The retail line alone is close to nineteen of those annual budgets.

What does the property itself cost?

An entry-level Mayfair flat averages about £1 million, an average home around £4.8 million, and the most expensive flats are valued at up to £200 million. Average rent is £1,387 a week. An average British household spends £118.40 a week on housing, fuel and power — Mayfair rent is nearly twelve times that.

Wetherell prices new-build in the area at £2,400 per square foot, with an average new home of 2,700 sq ft. Around 160 homes are under construction and 410 more in the pipeline, and £1.14 billion has gone into Mayfair's public realm over the past decade.

How many such households are there, and what do they contribute?

About 2,000. Their spending is estimated to bring roughly £2.5 billion to the UK economy. Westminster City Council, in the same body of research, put the contribution of Mayfair's prime homeowners at £2.3 billion a year. More than 60% of the area's residents were born outside the UK.

How much council tax do they pay?

This is where it gets odd. Westminster's 2026/27 council tax for Band D is £537.34 plus the Mayor of London's precept of £510.51 — £1,047.85 for the year. The council says it keeps the second lowest council tax in the country and has frozen its own element this year, raising only the adult social care precept, worth about 20p a week.

So a multi-million-pound house in the country's most expensive district carries a council tax bill comparable to an ordinary flat in an ordinary English town. English council tax is still calculated on what a property was worth on 1 April 1991.

How far can these numbers be trusted?

Honestly, it varies. The £676.60 a week is official ONS statistics, published on 11 June 2026. The council tax figures come from Westminster City Council, from a February 2026 decision. The detailed Mayfair household breakdown, though, is research by a private estate agency, Wetherell, drawing on Westminster City Council, Dataloft and EGI data, and it has been in public circulation since at least 2017. Prices have risen since, so read those sums as a floor rather than a current snapshot. Nobody publishes official statistics on the spending of the UK's super-rich households.
