How it's counted: companies incorporated Monday to Sunday, by registered post town, as read from Companies House. The week is frozen two days after it ends, so later changes to the register or to our rules don't alter it. Older weeks may not show sectors or websites, because we research companies for 30 days. Towns need at least 5 kept companies in a week to appear. Registered post town is where a company's office is, not always where it trades. See every source we use.

About the index

What the New Business Index is

Headline company formation figures count every new registration, including shells, holding companies and companies set up in bulk by formation agents. The New Business Index counts them too, then shows what's left once that noise is taken out.

Each week we read every company incorporated on the UK register and apply the same published rules. You get the total, the number struck out and why, and the likely new businesses that remain, for the UK and for each town with enough new companies to count.

Use it to see how many businesses are really starting in your area, compare towns, follow the trend over time, or find a figure for a story or report. It's free, and you don't need an account.

Questions

About the figures

What is the New Business Index?

A free weekly count of new UK companies, for the whole country and each town. It shows how many companies registered, how many our rules struck out as noise, and how many likely new businesses were left.

How often is it updated?

Every week. Each edition covers companies incorporated from Monday to Sunday and normally appears on the following Tuesday.

What counts as noise?

Companies registered at mass-registration addresses, companies with holding-style names, companies with only holding or dormant activity codes, and types that aren't normal trading companies. Being struck out doesn't mean a company is improper, and the rules will catch a few real businesses.

Why does London have so much noise?

Many formation agents and virtual offices have London addresses, so a company based anywhere can be registered there. Registered office is where a company's post goes, not always where it trades.

Do the figures change after they're published?

No. Each week is frozen when it's published, so a figure you quote today will still be on the page later, even if the register or our rules change.

Can I use these figures?

Yes. Quote them with credit to Firstfile and a link to the week you used. Each week has a citation line and a CSV of its town figures.

Does the index name any companies?

No. Every figure is an aggregate count. The only addresses shown are the busiest registered offices.
