Registered and based here

Active companies registered

3,710

At mass-registration addresses

122 (3.3%; median 17.7%)

At the registrar's default address

0

Active companies based here

3,588

Active companies whose registered office on the Companies House register is in the constituency, on 5 October 2026. Active means the status Active, including companies with a proposal to strike off. Every company type on the register is counted.

Active companies registered in the constituency, leaving out those at mass-registration addresses (an address line and postcode shared by 50 or more companies: formation agents, accountants, virtual offices) and those whose registered office Companies House has removed (the registrar's default address). A registered office is where a company receives official post; it is usually, but not always, where the company trades.

Active companies registered at an address shared by 50 or more companies (the same first address line and postcode), as a share of all active companies registered in the constituency.

New companies

5 October 2025 to 5 October 2026

September 2026

38 based here (40 registered here)

Companies incorporated in September 2026, the last complete month, on the same basis.

Companies entering insolvency

5 October 2025 to 5 October 2026

0

Administration

0

Creditors' voluntary liquidation

0

Compulsory winding up

0

Companies whose first Gazette notice of administration, creditors' voluntary liquidation or compulsory winding up was published from 5 October 2025 to 5 October 2026 (The Gazette, corporate insolvency notices held to 4 October 2026). A company is placed by the principal trading address its notice gives; otherwise by its registered office, unless that is a mass-registration or default address, which is usually the insolvency practitioner's office after an appointment. Companies that cannot be placed are counted in the UK total only. Across the UK, 10,715 of the 23,771 companies entering insolvency in this period (45.1%) could be placed in an area, so area figures count fewer companies than entered insolvency there. Members' voluntary liquidations are solvent and not counted; notices without a company number cannot be matched.

Industries

Active companies based in the constituency by the UK SIC 2007 section of their first SIC code. Dormant companies (SIC 99999) are shown on their own.

Balance sheets and filing

Latest accounts we hold for active companies based in the constituency, with a balance sheet date from 5 April 2024 to 5 October 2026. Figures are the companies' own filings, shown as filed and not audited by CompanyStack; figures that contradict each other are left out.

Companies whose latest accounts show net liabilities (net assets below zero), as a share of those whose accounts give net assets.

The middle value of net assets in those accounts, filed in pounds sterling (accounts filed in other currencies are not converted and are left out).

Active companies based in the constituency whose next accounts were due before 5 October 2026 according to the register, as a share of those with an accounts due date.

Active companies based in the constituency with a proposal to strike off on the register (status "Active - Proposal to Strike off"), as a share of active companies based there.

Owners aged 65 or over

Single owners aged 65 or over

6.5% of 1,882 companies with a single owner (median 7.9%)

Of the active companies based in the constituency with exactly one person with significant control holding 75% or more of the shares, an individual whose month and year of birth are published: the share whose owner was 65 or over throughout October 2026. Day of birth is not published, so an owner who turns 65 in that month is not counted. Shown only when at least 10 different people are 65 or over and at least 10 are under 65 (someone who owns several of these companies counts once).

Largest employers by filed head count

Up to ten companies based in the constituency with the largest average number of employees in their latest accounts, 10 or more (as filed: group accounts give the group's figure, which may include staff elsewhere). Companies only: limited liability partnerships, partnerships and other bodies are not listed.
