Newly Formed Companies in
Belfast
this week

There have been 10 companies formed in the week from 04-08-2026 to 11-08-2026 within the BT1 postcode district (Belfast in Belfast). Usually over 2500 companies get formed every working day across the country. If you would prefer to analyse by region, rather than this postal district, you can check how many companies are formed in Belfast.

The geography of BT1 is anchored by Belfast, making the district more specific than the broader postcode area that surrounds it. That single-place description makes BT1 relatively direct to interpret: it is centred on Belfast.

For BT1, the local setting is important: Belfast gives the district a Northern Ireland context shaped by civic institutions, regeneration, maritime history and a growing visitor economy.

Company registration numbers put BT1 in a strong national position, ranking 265th of 3,113 districts with 4,029 companies as of June 2026. Newly incorporated businesses using BT1 addresses appear within Companies House records for this part of Belfast. The figures place BT1 among the stronger-performing postcode districts in the UK for company registrations.

That local context helps make the company data easier to interpret, because BT1 is tied to identifiable places rather than an abstract administrative code.

Below are just a small sample of the companies formed (with the numeric parts of the address redacted with an X and not showing the postcode, so we are not advertising peoples full addresses online) but allows you to see where some of the companies have been formed. Our newly formed companies wizard in our Dashboard allows you to filter by a range of options free of charge to get an idea of quantities, prior to deciding to purchase. We supply the full company details lodged when they filed their company when you have decided on your filter selection and choose to purchase.
