Mantle
Methodology

One acquirability score,
from five weighted signals.

Every company in Mantle carries a single number from 0 to 100. It is not an opinion, a rating or an estimate - it is a weighted read of what the business has already filed. Five signals, all drawn from public accounts and Companies House records, combine into one score that ranks how acquirable a company looks today.

The five signals

100 points, weighted by what matters.

Margin carries the most weight, followed by the two timing signals, then the balance sheet and size. Each signal is scored independently from filed data and summed - no signal can be gamed by narrative alone.

01 Quality

Margin quality

30 pts

Operating margin from filed accounts - the single best signal of a healthy, well-run business. It carries the most weight because durable profitability is the hardest thing to fake and the easiest thing to underwrite.

02 Timing

Owner age

20 pts

The oldest active director’s age against the retirement window. Companies where the principal is 60+, 72+ or 80+ score progressively higher - proximity to retirement is what turns a good business into an available one.

03 Timing

Succession risk

20 pts

A sole director with no named successor - no second active director sharing the owner’s surname. When there is no obvious internal heir, a sale becomes the most likely exit rather than a family handover.

04 Quality

Balance sheet

15 pts

Cash relative to revenue. A cash-rich, low-debt balance sheet is simpler to transact, cleaner to finance and less likely to hide surprises in a data room.

05 Fit

Size fit

15 pts

Revenue against the search-fund sweet spot. Turnover of £2-10m scores highest - large enough to support a full-time owner-operator, small enough to acquire without institutional scale.

On every profile

Two sub-scores

The headline number is split into two reads so you can sort by intent, not just total.

  • Timing Owner age + succession risk - how close the exit is.
  • Quality Margin + balance sheet - how good the business is.
The universe

How the universe is built.

Before anything is scored, the field is narrowed to companies that could plausibly change hands to an individual buyer. Mantle tracks roughly 18,500 active UK companies that meet every one of the filters below. The score only ranks within that set - it never invents businesses that are not really for sale.

Financial and real-estate firms, holding-company shells and companies limited by guarantee - charities, schools and similar bodies with no shares to buy - are excluded outright. There is nothing to acquire, so there is nothing to score.

Status Active, filing UK company
Turnover £1m - £20m (filed)
Employees 5 or more
Oldest director Age 60+
Excluded Financial · real estate · holding shells · guarantee companies
Honesty

What the score is, and what it isn’t.

A screening signal
  • Built only from filed accounts and Companies House records.
  • Fully mechanical - the same inputs always produce the same score.
  • Designed to rank a shortlist worth a first conversation.
  • Refreshed regularly as new accounts and filings land.
Not investment advice
  • It is not a valuation and does not price a deal.
  • It cannot see intent - a high score is not a company for sale.
  • Filed figures lag; a score reflects the last accounts, not today.
  • Every target still needs your own diligence before you act.
