Specialist M&A advisors for building services and healthcare owners
DealFlowAgent advises owners selling businesses valued between £500K and £100M. We run confidential, competitive sale processes backed by a proprietary network of more than 13,000 acquirers, so owners negotiate with several serious buyers rather than accepting the first approach that lands.
Senior advisors handle every mandate. Sector focus, direct buyer relationships and our own research tools replace the listing-and-waiting model most owners are offered.
Why we exist
Most owners sell once. The buyer across the table has done it many times. That imbalance costs sellers real money, usually through an unchallenged first offer or a structure that pushes value into an earn-out nobody defends.
We give owners of £500K to £100M businesses the same standard of representation that mid-market private equity takes for granted.
How we work
Human-led, intelligence-led. Senior advisors own the relationship and the negotiation. Our research tools map the acquirer universe, rank buyers on fit and capability, and surface live intent before we make an approach.
The result is a shorter list of better-qualified buyers and a process that keeps competitive pressure on price from first contact to completion.
What we actually do
Three phases, one objective: the highest defensible price on terms you can live with.
Position and prepare
We build the equity story, normalise earnings and remove the issues that buyers use to discount price before your business reaches the market.
Run a competitive process
We approach a ranked list of trade, private equity and strategic acquirers from our network so you negotiate with several parties, not one.
Hold value to completion
We manage diligence, deal structure and the earn-out mechanics so the headline number survives to the wire transfer.

Duncan Moore
M&A Deal Lead
Joined full-time on 22 August 2026 from the largest M&A advisory firm in the UK, owned by K3 Capital. As an ex-Director he managed teams of M&A advisors, analysts and associates, working daily with business owners, buyers and stakeholders on live acquisition deals. Selected from 260 applicants alongside colleagues from investment banking backgrounds, he brings that experience and network to lead the advisory bench across Building Services, Facilities Management, and Healthcare.

Martin is one of the most well-connected figures in UK fire, security, building services and FM. He is Chairman of both the Fire Industry Association and the British Security Industry Association, the only person in the UK to hold both roles simultaneously. Martin spent over a decade in senior leadership at Mitie, latterly as Industry Liaison Director for its fire and security division, helping scale the business past £500m in revenue and playing a role in the £366m acquisition of Marlowe plc, which created one of the UK's largest compliance, fire and security services groups. He joined DealFlowAgent because owners in these sectors deserve a genuine sector-specialist advisor across valuation, business optimisation and buyer access. In recognition of his industry roles, he acts in a personal, non-partisan capacity.

Nick leads FM Talent Partners, the facilities management and real estate leadership search firm, and is a leading specialist in building services and FM management talent. He partners with DealFlowAgent on two-way referrals: helping business owners and acquirers fill the key roles that decide whether a business is sellable, and introducing owners who are thinking about their next chapter to a team that knows their industry and their market. Key-person dependency is one of the two most common reasons a sale collapses, and Nick fixes it at source.

Confidentiality is the default
Your business is never named or described to a buyer without your written approval on the specific party and the specific wording.
Buyers see an anonymised profile first. Identity is released only after they qualify and sign.
Staff, customers and competitors learn nothing until you decide the timing is right.
