Dining out in London during the colder months can do a bit of good without any extra effort on your part. That is the idea behind StreetSmart, a charity scheme that partners with restaurants across the capital (and beyond) to raise money for people experiencing homelessness.

Here is how it works in practice. Participating restaurants add a voluntary £1 donation to each table's bill during November and December — typically the months when demand for homelessness services peaks. Diners can ask for it to be removed, no questions asked, but most leave it on. The restaurant passes the money on, StreetSmart distributes it to grassroots charities working with homeless people, and the guest gets a warm glow along with their pudding.

The scheme has been running since the late 1990s and has raised millions of pounds over that time, with the cash going to small local organisations rather than large national bodies — the sort of shelters, outreach teams and advice services that often struggle for funding. Restaurants sign up for free, and the admin is handled by StreetSmart, which is one reason so many independent venues in London keep coming back to it each year.

For travellers, the appeal is simple: it requires no planning, no extra stop and no research. If the restaurant you have already booked is part of the scheme, your table becomes a mini fundraiser by default. Look for the StreetSmart sticker or mention on the menu or bill, particularly during the winter campaign period. And if you run into it elsewhere in the UK — the scheme has expanded beyond London over the years — the deal is the same: one pound per table, entirely optional, entirely passed on.

It is also a low-friction way for visitors to engage with an issue that is visible on London's streets, without the awkwardness of deciding how to give on the spot. Money raised goes through an established channel to vetted local projects, which is more effective — and more transparent — than ad-hoc street donations.

Who should care? Anyone eating out in London between November and December, really. Families, couples on a city break, business travellers expensing dinner — the £1 barely registers on a restaurant bill, but across thousands of tables it adds up to serious money for the charities receiving it. If you want to go a step further, you can check which venues near you are participating before you book and make your reservation accordingly.
