Each row comes with the facts behind its score, financials with dates and contact details.
What's in the file
One row per firm, in Approach Score order, as Excel + CSV.
It holds the facts behind each score, points for each part of the score, financials with dates, publicly available contact details, where identified, director names and named shareholders.
Some people with significant control appear as Other individual, with no further detail. Director email lookups are not included.
How this list is filtered
- 10 or more staff, from filed headcount or our estimate where none is filed.
- Registered office in London.
How this list is built
The Approach Score ranks firms mainly on public Companies House information about owner tenure and age, ownership, size, financial strength and recent register changes.
Firms with higher scores appear first in each list.
Use the ranking to order research, then check each business directly.
What it does not mean
No firm here is for sale, and the score says nothing about any owner's plans.
At least 95% of the firms where we hold directors had them checked in or after November 2026.
What we do not cover
Regulatory information is not included in this list. Buyers should check the relevant register as part of their due diligence. IT services firms have no single sector regulator; for managed services, check whether the Information Commission's cyber security remit applies. Check any Cyber Essentials certification through the NCSC's certificate search.
Why age bands but no people's names
Age bands come from the month and year of birth on Companies House. This page shows no exact ages and no people's names. Both come with the purchased list. The band edges from 45 to 65 are the ages where the score changes. A row shows no age bands when a director's surname is in the firm's name, its group's name or its website. Those directors' ages still count towards the score.
Is this your firm?
You can ask us to take it off every acquisition page, and out of every list we sell after that. Give us your name and work email, and we send you a link to confirm. If your email address is on the firm's own website domain, the firm comes off once you confirm. If it is not, a person reviews your request first. A list already sold stays with its buyer.
