A British start-up that uses an AI agent to run household admin has raised £13m to expand. Nous, founded by onefinestay's Greg Marsh, pitches itself as a personal assistant for the dull, costly jobs most people put off: finding cheaper deals, switching energy and broadband providers, cancelling unused subscriptions, flagging unfair contract terms and filling in forms. The round was backed by Heartcore Capital, with existing investor Mosaic Ventures and a notable list of angels including Monzo founder Tom Blomfield and lastminute.com's Brent Hoberman. The company says almost 250,000 UK homes already use it. That number, and the savings claims around it, come from Nous itself, so they are worth treating with care even as the raise and the backers are real.
This piece reflects reporting as of October 2026. Adoption and savings figures are reported by the company and are not independently audited.
What it actually does
The promise is to take the mental load of "life admin" off a household. Beyond switching and cancelling, Nous says it manages family calendars, sends deadline reminders, finds local tradespeople and books appointments. The part that sets it apart from a generic chatbot is that it is registered with the Financial Conduct Authority, which the company says lets it carry out regulated activities such as arranging insurance on a user's behalf rather than just pointing them at options. In agent terms, that is the meaningful line: the difference between software that advises and software that acts.
Marsh says Nous manages an average of £2,765 of annual spending per household, more than £685m across the UK in total, though the company does not report how much users have actually saved. He is candid that the product is aimed at ordinary households rather than early adopters, describing it as "not a toy for tech bros" and saying most users are working parents, often women.
The case for it, and the catch
The case is easy to feel. Switching and cancelling are tasks almost everyone underdoes, loyalty penalties are real money, and a tool that chases them down could genuinely pay for itself. Nous also says it tries to guard against the obvious failure mode of a chatbot acting on your money: it pairs large language models with rules-based logic for sensitive steps, which the company says reduces the risk of hallucinated or serious errors. That is the right instinct, because the gap between "drafts an email" and "buys a financial product in your name" is exactly where an agent's mistakes get expensive.
The catch is that you are delegating decisions, and some of them are financial. An agent that switches your energy or arranges cover is making choices you would normally sign off yourself, and the safeguards that stop a wrong switch or a bad policy are, again, described by the company rather than independently tested. There is also a plain question the coverage does not answer: On money, Nous is clearer than many: it charges a subscription rather than selling data or running ads, with a free tier that manages up to two household services and a Premium plan at £6.99 a month for unlimited services, 24/7 support and cash rewards. The question that remains is whether it also earns commission from the providers it switches you to, because that, more than the monthly fee, is what would shape whose interest the agent is really serving.
FAQ
What is Nous?
A UK start-up whose AI agent handles household admin, switching providers, cancelling subscriptions, filling in forms and arranging some regulated services such as insurance. It has just raised £13m.
Can it really buy things on my behalf?
The company says it is FCA-registered, which allows it to carry out some regulated activities such as arranging insurance, rather than only making suggestions. It says sensitive actions go through rules-based checks as well as AI.
Are the "250,000 homes" and savings figures reliable?
They are reported by Nous and are not independently audited. The funding round and investors are confirmed by trade press; the adoption and spending figures should be read as company claims.
How does it make money?
It charges a subscription. There is a free plan that manages up to two household services, and a Premium plan at £6.99 a month for unlimited services, 24/7 agent support and cash rewards. The company says it does not sell data or take advertising. What is less clear is whether it also earns commission from the providers it switches customers to.
The takeaway
Nous is one of the more tangible consumer AI-agent stories to come out of the UK: a real product, a serious investor list and a problem, household admin, that genuinely wastes people's time and money. The reasons to pause are not about whether the idea works but about trust and transparency: the headline numbers are self-reported, the safeguards on financial actions are unverified from outside, and it is worth knowing whether the £6.99 subscription is the whole story or whether commissions from providers sit alongside it. An agent that acts on your money is a bigger ask than one that drafts your emails, and the sensible response to a £13m raise is interest tempered with those questions, not a leap of faith.
