The world is still built for pairs – single women are paying the hidden penalty

More women are choosing to build full, self-directed lives outside of traditional couplehood — and many are happier for it.

Mintel reports that 61% of UK single women say they are happy being single, and 75% haven’t actively tried to find a partner in the last 12 months. In other words: for many women, singlehood is no longer a waiting room for “real life” – it is real life.

We’ve been exploring the psychology of this rise in singlehood which will be outlined in our upcoming report — The Sovereign Single: The Rise of the Uncompromised Consumer. Sign up below to be one of the first to receive it.

But while culture is changing, many systems still aren’t.

Across policy, finance, housing and everyday services, modern life still quietly assumes a household of two: shared income, shared labour, shared admin, shared backup. That leaves single women paying a hidden penalty and not just financially, but in mental load and emotional strain too.

This social issue is a growing design blind spot for brands.

It makes it expensive to be single – the big-ticket moments and the everyday ones too, for example:

• Many government policies still favour married couples in taxation, inheritance and benefits structures, effectively rewarding household coupling and shared risk.
• Mortgage underwriting and lending systems often favour dual-income households, meaning a single high earner may still be treated as a riskier proposition than a couple with the same combined income.
• In the UK, ONS analysis found that people living alone spend a higher share of their disposable income than two-adult households, with a greater proportion going on housing, food and furnishings.

And the hidden penalty doesn’t stop at the wallet.

Our research suggests three critical ways this shows up for single women today — and, importantly, three major opportunities for brands willing to design for a world that is no longer pair-default.

Overloaded – Reduce the competence burden

Single women have to bear the brunt of added financial pressure (women are disproportionately affected by the cost-of-living crisis and financial stress), design fatigue from collective adminstrative tasks and increased rates of burnout. We’re already seeing some brands tackle this challenge with creative solutions and success:

• Meal Kits: Deciding what to eat three times a day is a relentless mental loop. By optimizing single-serve portions and bypassing the supermarket entirely, these brands successfully fulfill the psychological job of “outsourcing the brainwork.”
• Skylight Calendar: This digital touchscreen calendar explicitly ran an award-winning campaign targeting the “Parental Mental Load.” By creating a centralized, automated hub for logistics, they aren’t just selling a screen; they are externalizing memory work so a single parent doesn’t have to hold every detail in their head
• Joolz & Bugaboo (One-handed strollers): For a solo parent, physical friction triggers cognitive panic (imagine holding a baby, a bag, and a ticket while trying to board a bus alone). Brands that engineer flawless “one-hand folds” directly reduce competence burden, keeping the parent out of a high-stress state

So What: If single women are carrying more of life’s admin alone, brands that reduce decision load, friction and memory work will win disproportionate trust. Don’t just offer choice — reduce the work of choosing.

On high alert – Design for emotional regulation and reliability

The build up of emotional stress related to increased financial and executive responsibility also presents a chance for brands to lean into product design and messaging that creates a sense of comfort, trust and reliability for consumers. For example:

• Ring & SimpliSafe: For women living alone, physical safety is a primal, physiological need. These security brands market to single demographics by focusing on empowerment rather than fear. They offer the emotional comfort of a silent guardian watching over the home
• The National Trust (UK): Historically, “family tickets” were strictly priced for two adults and two children, penalizing single parents financially and emotionally. By introducing single-parent family tickets, the National Trust performed a massive emotional job: validation. They sent the psychological signal, “We see your family structure as whole and valid,” which fosters deep, long-term brand loyalty.
• Ellevest: A financial investing platform built for women’s financial realities (longer lifespans, career breaks, gender pay gaps). For a single woman reliant on one income, financial missteps feel existential. Ellevest provides the emotional comfort of a highly predictable, trustworthy roadmap, easing the dread of financial independence.

So What: For women carrying more financial and executive responsibility alone, the premium is not just on convenience — it is on calm, trust and predictability. Brands that feel reliable, validating and low-drama can become emotional infrastructure, not just functional providers.

Under-supported – Build for care networks

While women might be proudly choosing to ‘live life single’, when the human biological drive for partnership is blocked or deprioritized, that energy doesn’t vanish – it is redirected – seemingly into consumption, self-optimization, and the environment. For brands, this can be a chance to recognize additional spend on self-care, attachment to non-human objects and the need for connection. Group trips, joint subscription services and single-parent networks have all thrived in recent years. For example:

• Frolo: An app built exclusively to connect single parents. It taps into the psychological need for a “village,” allowing solo parents to coordinate meetups, share advice, and build a reliable care network. It cures isolation by facilitating peer-to-peer attachment.
• Flash Pack / group trips and activities: A travel company specifically designed for solo travelers in their 30s and 40s. Solo travel can trigger anxiety about loneliness. Flash Pack curates group adventures, perfectly motive-matching the desire for autonomous exploration with the psychological safety and belonging of a curated peer group.

So What: The opportunity is no longer just to serve individuals or couples — it is to support care networks. Brands can create growth by helping single women sustain belonging through easier coordination, shared rituals, and friend-/family-compatible experiences.

Single women do not need the world to be redesigned around pity or “empowerment” slogans. They need systems, services and brands that recognise a simple reality: too much of modern life is still built for pairs. That creates a hidden penalty – in money, mental load and emotional strain – but it also creates a clear opportunity for brands willing to design differently.

On International Women’s Day, a good question for any brand is:

Where is our category still built for a two-person default?
