Starting a company in Windsor?
New directors have two fixed deadlines: the confirmation statement a year after incorporation and first accounts at 21 months. Free reminders cover both. Accountants and local services can get this list as a weekly CSV for the SL area.
How we count
The data comes from the UK public register of companies, reused under the Open Government Licence v3.0. Each night at about 02:10 UTC we collect the previous day's incorporations, add each company's filing deadlines from its record on the register, and publish the update by about 06:40 UTC.
“This week” means the seven days before today, by date of incorporation, in UTC. Cities are grouped by the place name in each company's registered office address, so a company is counted where its registered office is, which is not always where it trades.
Known gaps: companies dissolved or restored soon after incorporation, and records corrected late on the register, can take a day or more to show here. Last updated 26 October 2026.
