Roughly three-quarters of Britain’s private sector businesses employ nobody at all. That single official statistic explains why a survey about where companies physically start has more weight than it first appears: for most British firms, the founder’s home is not a stepping stone to premises, it is the premises.
Research commissioned by Starling Bank from 1,500 small and medium-sized business founders, published on 28 July, puts a figure on it. It reports that 51% of the UK’s small businesses begin in shared households, and it then tries to price the thing nobody invoices for: the labour of the people who happen to live there.
What the Survey Found
Businesses that started in shared households went on to generate average revenue of £530,451, the research says, with one in seven passing £1 million.
That average deserves a moment’s scepticism. A mean of £530,000 sitting alongside a 14% tail above £1 million is the signature of a skewed distribution, not a typical outcome. The median firm in this group almost certainly turns over far less than half a million, and the average is being pulled upward by a minority of large ones. It is a real number, but it is not the number most founders in the sample will recognise.
The support itself is easier to read. Household members contribute an average of 11 hours of unpaid work a week. Twenty-nine per cent help pack orders and make deliveries. Twenty-seven per cent give the founder leeway on household responsibilities, which is a polite way of saying somebody else did the washing up for two years. Forty-three per cent of founders said the people they lived with played a key role in launching the business or keeping it alive, and 36% said flatly that they could not have succeeded without them.
The £7,200 Is a Valuation, Not a Payment
The headline figure attached to that labour is £7,200 a year. It is worth understanding exactly how it was built, because the construction is stated in the research’s own footnote and it changes what the number means.
The calculation takes 10.92 self-reported hours a week, prices them at the £12.71 hourly minimum wage for workers aged 21 and over, and multiplies by 52. That produces £7,217.25.
Two things follow. The first is that no money changes hands: this is an imputed value, an estimate of what the same hours would have cost at the legal floor for wages. The second is that the minimum wage is a deliberately conservative rate. Some of the work described, particularly the business advice and financial guidance covered below, would cost considerably more than £12.71 an hour to buy. The figure is a floor rather than a valuation of the help’s real worth.
Parents Are the Largest Single Source of Capital Here
Among founders who lived with a parent or guardian, 70% received direct financial support, averaging £9,763. Adding the value of free workspace, utilities and meals brings the total to nearly £23,000 per founder.
Set that against the way early-stage funding is usually discussed. A £9,763 cash transfer from a parent will never appear in a funding round table, has no term sheet, no valuation and no press release. Yet at the scale the survey describes it is doing more work across the British business population than most institutional seed capital, simply because it reaches vastly more companies.
Parents also supplied about nine hours of unpaid labour a week on top of the money, and the non-financial help was substantial: 42% of founders said a parent provided financial guidance, business advice or lessons from running their own company, and 29% cited emotional support during difficult periods.
Bola Sol, the financial adviser and author Starling partnered with for the campaign, made the point about accounting directly. “That support is real capital, even if it never shows up in the accounts,” she said, adding that she started her own first business “in my childhood bedroom at my mum’s house in Brixton”. Her practical advice was narrower and more useful than the headline: separate business money from personal money from day one, and set money aside for tax early.
Three-Quarters of British Businesses Employ Nobody
The official statistics give the survey its context. Department for Business and Trade business population estimates put the UK at 5.7 million private sector businesses at the start of 2025. Of those, 5.64 million were small, employing between zero and 49 people. Small and medium-sized firms account for 99.85% of the entire business population.
The decisive figure is the split on employment: 1.4 million businesses, or 25%, had employees, while 4.3 million, or 75%, employed nobody beyond the owners. A further 3.0 million businesses, 54% of the total, traded without being registered for either VAT or PAYE.
A business population shaped like that is overwhelmingly domestic by default. The question is not whether British companies start at home; most of them never leave.
The Office for National Statistics adds the other half of the picture. Its business demography figures recorded 14,330 high-growth businesses in the UK in 2024, up from 13,750, with the high-growth rate at 4.9%, its highest since 2018. Business deaths fell to 280,000, the lowest death rate since 2016. Household subsidy is not the reason firms grow quickly, but it plausibly affects how many survive long enough to try.
The Friction Is Real, and Mostly About Bandwidth
Forty-four per cent of founders reported friction with the people they lived with. The causes are mundane and specific: heavy use of shared Wi-Fi for business calls and downloads (34%), clients, suppliers and deliveries arriving at the home (34%), and higher utility bills (32%).
None of that is trivial when the household is also the warehouse. The list is a reminder that the arrangement transfers real costs onto people who did not choose them, and that the transfer is mostly invisible because it arrives as a slightly larger electricity bill rather than an invoice.
It also points at something the survey does not quantify. Founders whose households can absorb a doubled broadband load, a hallway full of stock and an extra £30 a month on energy are not a random sample of the population. The support described here is unevenly available, and the businesses it enables are correspondingly uneven in who gets to start them.
Most Founders Pay It Back, and Some Pay It Forward
Nearly three-quarters, 74%, went on to repay the family members who helped them. A third treated them to a holiday or an experience, one in five contributed towards a mortgage, and 21% now provide a regular allowance funded by the business.
The repayment ran in a second currency too. Thirty-nine per cent of founders taught household members online banking and digital money management, 36% helped them use smartphones confidently, and 36% introduced them to everyday technology, software and AI tools. Capital flowed one way and digital literacy flowed back the other.
The gaps founders themselves identified were financial rather than technical. Twenty-eight per cent said they would benefit from more money management support, most often on tax obligations (38%), budgeting and forecasting (35%), and visibility over cash flow and transactions (30%). Those are the three areas where an underpriced start becomes an expensive problem later, because a business run on informal support often runs on informal bookkeeping as well.
Who Commissioned This, and What It Leaves Out
The research was commissioned by Starling Bank, which sells business current accounts, and the write-up ends by listing the bank’s own tools for tax pots and spending insights. Sami Kade, its banking product director, framed the finding as evidence that founders can “keep overheads low while also making the most of the support from friends and family”.
That is a fair reading of the data and also a marketing position, and both things can be true at once. The figures are self-reported by 1,500 founders rather than drawn from accounts, the revenue average is skewed, and the £7,200 is imputed at minimum wage rather than observed. None of that makes the survey wrong. It makes it a survey.
What survives the caveats is the shape of the thing. A large share of British businesses are launched inside households that quietly underwrite them, in labour, cash and tolerance, and none of it is recorded anywhere. When the small business sector is described as fragile, as it was when confidence hit the weakest level the FSB has recorded, the fragility is partly this: a support base that is invisible, unbudgeted and dependent on somebody else’s spare room. It is also why the margins are so thin at the bottom, where most small traders earn less than the wage they are obliged to pay staff.
