    The Off-Market Register: businesses that are not for sale

    Private companies in building services, facilities management and healthcare that are not running a sale process, and would sell to the right buyer at the right price.

    Each owner has worked with the DealFlowAgent team to prepare a mandate: a valuation, a written reserve figure and a banded profile. They are not on the market and they are not advertised anywhere. If a verified acquirer meets the reserve, the owner will sit down and talk. Nothing below it reaches them.

    If you are a business owner, start here. If you acquire businesses, scroll to Register interest as a buyer.

    Value my business

    Ninety seconds. No cost. Nothing published.

    View current mandates

    Not for sale, but open

    No sale process is running. The owner has told us the number at which they would seriously engage.

    Prepared in advance

    Accounts reviewed, figures banded and verified, reserve agreed in writing before anything is published.

    Anonymous until approved

    The company is never named here. The name goes to one verified acquirer, with the owner’s written approval.

    Why each business is called a project, and what that means

    Every mandate is given a project codename, as is standard practice in mergers and acquisitions. It is a working label chosen at random by DealFlowAgent so that a business can be discussed with acquirers, lawyers and funders without the company, its staff or its customers being identified. The codename means nothing on its own. Searching it will not return the company, because the name exists only inside this register and the documents that sit behind it. When you read Project Halyard, read it as the label on a sealed file rather than a brand. The plain description above each project tells you what the business actually does, where it operates and what size it is.

    This is not a business-for-sale website

    Your company is never named on this website. It is never advertised, never circulated to a list, and never shown to anyone who has not been verified first. Most owners on this register are not selling. They are growing, they intend to keep growing, and they are fielding several unsolicited approaches a month with no way to tell a credible acquirer from a speculative one.

    What a public business-for-sale website does

    What the Off-Market Register does

    Publishes your company name

    Publishes a banded, anonymous profile only

    Anyone can see it

    Acquirers are verified before they see anything

    You are visibly on the market

    You are not running a sale process, and the page says so

    Every enquiry lands on you

    Every enquiry lands on us

    You find out what you are worth from the first offer

    You set the figure in advance and nothing below it reaches you

    It stays up until it sells

    Each mandate runs for 45 days, then comes off

    We stand between the owner and the approach.

    How confidentiality works here

    Six protections, on every mandate, without exception.

    Your company is never named on this page.
    At any stage. Not in the title, not in the text, not in the illustration. The name is released to one specific acquirer, only after you have approved that specific introduction in writing.
    Every figure is published as a band.
    A precise turnover, a filing date and a region will narrow most UK sectors to a single company. Bands are wide enough to protect your identity, and wide enough that a growing business does not fall out of its own mandate. Every band is checked against filed accounts and management information before it is published.
    Independent checks before anything goes live.
    We test the page for re-identification before it is published. We ask an artificial intelligence model to name the company from the page alone, we sense check it with a senior figure who knows the sector, and we run the bands through Companies House filters to confirm the resulting set of companies is large enough to hide you. If any of those checks points at you, the bands widen or the mandate does not go live.
    Documents are watermarked to the recipient and every view is logged.
    You can see who has opened what, and when. If a document moves, we know whose copy it was.
    Each mandate runs for 45 days.
    Then it comes off the register unless you renew it. A company that sits visible and inactive is a company whose position weakens. We do not allow that to happen to you.
    No public process, ever.
    No advertisement, no open circulation, no third-party syndication, and no presence on any public business-for-sale website. Your staff, customers and suppliers have no way of knowing this page exists.

    What a reserve figure is

    A reserve, as at auction. The owner sets it in writing before the mandate goes live. It is private, it is disclosed to verified acquirers at non-disclosure agreement stage, and it is a threshold for engagement rather than an asking price or a cap.

    The four gates

    How an acquirer moves from first contact to the company being named.

    01

    Acquirer verification

    Funding, sector experience, prior completions and decision authority are confirmed first.

    No company information released

    02

    NDA and financial pack

    A short non-disclosure agreement releases the figures, the reserve and the contract base.

    Identity withheld

    03

    Owner approval

    The owner reads a written profile of the acquirer and decides. Only then is the company named.

    Owner's written approval required

    04

    Indicative offer

    Acquirers who meet the reserve are invited to offer. More than one qualifying, we run a process.

    Reserve must be met

    Who we accept

    What we look for

    • £2.5M to £30M of revenue, most mandates £6M to £18M
    • Profitable, or within 10% of breakeven with a clear path
    • A meaningful base of contracted or repeat revenue
    • Essential services: fire and life safety, HVAC and mechanical, lift and escalator, electrical, security, facilities management, testing and compliance, and healthcare
    • An owner willing to set a reserve

    What we decline

    • Sectors where we do not already hold qualified acquirers
    • Owners unwilling to set a reserve figure
    • Figures that cannot survive the re-identification checks
    • Businesses already represented on an exclusive basis

    We decline more than we accept. That is what makes the register worth an acquirer's attention.

    If you own a business

    Start with the valuation. Ninety seconds, no cost, and nothing you enter is published anywhere. If the result is interesting we will talk about whether a mandate makes sense for you. There is no obligation to sell, and no obligation to sell with us.

    If you acquire businesses

    Verification takes under a working day. On approval you receive the financial pack, the reserve and the contract base analysis under a non-disclosure agreement.

    Questions owners ask


    All figures on the Off-Market Register are published as bands and are verified against filed accounts and management information. Nothing on this page constitutes an offer or an invitation to treat. DealFlowAgent (DFA) is a trading name of BTB Holdings Ltd, registered in England and Wales.

    End of mandate  ·  About DealFlowAgent, the advisory firm behind it

    For business owners

    Every mandate here started with an owner who was not ready to sell

    They wanted to know what their business was worth, who would realistically buy it and what those buyers would pay, without anyone in their market finding out they had asked. We did the legwork. If the right buyer turned up at the right number, they had a decision to make. If not, nothing changed and nobody knew. That is the whole idea.

    01

    We find and qualify the buyers

    We approach acquirers from a network of more than 13,000, confirm funding and intent, and only bring you parties who can actually complete. You never chase anyone.

    02

    Your name stays out of it

    Your business is presented in bands, under a codename. Staff, customers, suppliers and competitors learn nothing. The company is named to one acquirer at a time, only once you approve that introduction in writing.

    03

    You find out what it is worth first

    Most owners start with a valuation and a view of who would buy them, years before they are ready to move. There is no obligation to sell, and no fee to find out.

    Two ways to start, both confidential

    Get an indicative valuation range and a view of who would buy you, or speak to us first. A discovery call takes twenty minutes, covers what your business would be worth today, what would move that number and how we keep your identity protected. No fee, no obligation, no contact with any buyer until you say so.

    Get a free valuation

    Owners typically speak to us one to three years before they transact. Early is normal.
