Research · Companies House fee rise

What the £50 incorporation fee did

Incorporations fell 15% when the fee went from £12 to £50 in May 2024 (May to August, against the same months of 2023). More than half of the companies that stopped being formed would have been struck off; the number that go on to trade didn't fall.

Biggest movers

Change in companies formed at their own address (agent and virtual-office registrations excluded, so a formation agent moving office doesn't appear as a boom), for councils with at least 30 such companies in both months. Small councils move a lot from month to month; treat a single month's change as a prompt to look, not a trend.

Busiest councils

Ranked by companies formed at their own address, because raw counts favour the districts where formation agents and virtual offices are based; the full count and the agent-address share are alongside.

Mostly one address: in West Suffolk (87% of 866), Camden (86% of 4,073), Islington (86% of 2,348), Hackney (84% of 2,683), Westminster (55% of 1,746) more than half of the month's registrations were at mass-formation or virtual-office addresses. A formation agent based in a district isn't a local business boom, which is why this table ranks councils by companies formed at their own address.

The full table for all 360 councils is in councils.csv. Each council also has a weekly page with this week's companies: find yours.

Method, in brief

We count every incorporation on the Companies House register on the day it was formed (companies limited by shares or guarantee and LLPs). "Expected to trade" applies the historical trading rate of companies formed at the same mass-formation address or in the same SIC section, from 2.5 million companies with known outcomes. It's an estimate for the group, not a judgement on any company. Year-earlier comparisons start from companies still on the register today and are corrected for the share dissolved since. Full method and accuracy.

Which of these companies will actually trade, and how to reach them. Every Monday, for your council.The whole week's list ranked A to E with verified websites and contacts. Two weeks free, then £29 a month per council. That's the founding price, locked for twelve months (£49 standard).
