The founder who spent 18 months slashing costs to lift EBITDA before going to market, only to watch a buyer’s accountants reverse much of it in the first week of due diligence, is a pattern UK corporate finance advisers know well. Buyers in the UK SME market pay on a multiple of normalised EBITDA, not your statutory profit figure, and the difference between those two numbers is exactly where pre-sale improvement work holds up or quietly collapses.
If you run a services firm with five to fifty people and you are thinking about exit in the next two to four years, this is the practical sequence.
What does EBITDA improvement before a sale actually mean?
Buyers use EBITDA as a proxy for the sustainable, recurring earnings they are acquiring. Before they apply a valuation multiple, their accountants will normalise the figure, adjusting out anything that reflects you as an owner rather than the business as a going concern. UK M&A advisers including Consult EFC and E2E Accounting note that premium multiples go to businesses with two to three years of clean, comparable, and consistently improving adjusted EBITDA.
The practical implication is that a sudden jump in EBITDA in the months before a sale will be treated with scepticism. Buyers look for trends, and a trend requires time to establish. Consult EFC recommend a 12 to 24-month window for building what they describe as sale-ready EBITDA, focused on recurring revenue, reliable reporting, and sustainable margins rather than short-term cuts. That is the frame this playbook sits inside.
Why does how you got there matter as much as the number?
Normalisation cuts both ways. If you pay yourself more than the market rate for your role, the excess can be added back to EBITDA as a defensible adjustment. If you run personal expenses through the company, those come out too. But if you have cut headcount below what the business needs to function properly, a buyer’s accountant adds those costs straight back in, and your adjusted figure drops accordingly.
Windes, an M&A accountancy firm, outline three primary normalisation levers for owner-operated businesses: standardising director pay to market rate, removing lifestyle expenses run through the company, and reclassifying major assets that were incorrectly expensed as repairs rather than capital expenditure. Each adjustment must be evidence-based and consistent across the historical period you are presenting to buyers. Unjustified reclassifications get spotted in financial due diligence, and in the worst cases they damage trust and end the deal rather than improving the price.
The counterintuitive result of over-aggressive cost cuts is this: reducing headcount or under-investing in delivery capability can lower your valuation multiple even as reported EBITDA rises. DealFlowAgent, a US and UK M&A advisory, note that businesses with EBITDA driven by revenue quality and customer mix command higher multiples than those where the same figure has been achieved through cost reduction alone.
Where do the real gains come from in a services firm?
For a 10 to 50-person services firm, EBITDA improvement tends to come from four places: customer mix, pricing, operational efficiency, and working capital. Structural changes across these levers can deliver a 10 to 25 percent EBITDA uplift over 12 to 18 months when done systematically, according to DealFlowAgent’s advisory data. The starting point is usually customer profitability, because it is the fastest to quantify and the most concrete to act on.
Run a customer profitability analysis and identify which relationships are actually contributing to margin. Many services firms have grown their revenue while quietly accumulating low-margin work, often because the founder closed those deals and nobody wanted to revisit the pricing later. Segmenting by profitability, re-pricing under-valued engagements, and exiting contracts that consume disproportionate time are typically the fastest structural routes to EBITDA improvement. DealFlowAgent cite a 20 to 35 percent EBITDA uplift from customer portfolio work in firms that apply this systematically. ExecCapital, a UK corporate finance advisory, similarly prioritises higher-margin service lines and recurring retainers as the most direct route to sale-ready EBITDA.
On the operational side, process-mapping your core delivery workflows and automating accounts payable and receivable can reduce margin leak without affecting delivery quality. Working capital optimisation, tightening receivables cycles and renegotiating payables terms, can improve EBITDA margins by a further five to 15 percent while strengthening cash generation, according to DealFlowAgent’s data.
When should you start, and in what sequence?
UK exit-planning advisers commonly recommend starting 12 to 36 months ahead of a formal sale process. Buyers look for a trend, not a point-in-time figure, and demonstrating a credible one requires time you cannot manufacture at the last minute. Two to three years of clean, comparable accounts support a premium multiple. Starting early gives you the runway to normalise, improve operations, and show buyers a business that holds together under scrutiny.
A practical sequence, synthesised from UK advisory sources including Consult EFC, Windes, and ExecCapital:
Months 0 to 3: financial clean-up. Standardise director pay to market rate, remove personal expenses from the P&L, and correct any misclassified capital expenditure. Set up a faster month-end close process, targeting completion in under five days, and create dashboards that track EBITDA, margins, and utilisation. These give you a clean baseline and signal to buyers that the finance function is actively managed.
Months 3 to 9: customer and pricing work. Conduct a customer profitability analysis, re-price or exit low-margin contracts, and push for more recurring revenue through retainers or managed service agreements. Selective price rises on stable, high-margin clients are often achievable without significant churn where the relationship is strong.
Months 6 to 18: operations and technology. Process-map core delivery workflows, reduce rework and handoff bottlenecks, and automate accounts payable and receivable. If you are using AI tools anywhere in the business, document them clearly now. Buyers conducting due diligence on AI-enabled businesses increasingly check whether AI use is governed, compliant, and auditable. The ICO has specific guidance on AI and data protection under UK GDPR; undocumented use creates contingent liabilities that reduce deal value or certainty.
Months 9 to 24: governance and sale preparation. Prepare a data room with at least three years of clean accounts, key contracts, and documented KPIs. If your firm operates in regulated financial services, align with FCA operational resilience rules around any outsourced or AI-enabled business services before the formal process begins. Start conversations with a corporate finance adviser early enough to avoid being rushed into terms.
What else matters alongside EBITDA?
Buyers pay a multiple of EBITDA, but they apply that multiple based on confidence in the business as a going concern. Faster, cleaner management reporting is one of the most underestimated factors in reaching a full multiple. Consult EFC’s UK guide notes that buyers pay a premium for what they describe as a “turnkey business”; if due diligence surfaces a chaotic finance function, they reduce the valuation rather than take on the work of fixing it.
Three other factors sit alongside EBITDA in a buyer’s calculation and deserve attention before any sale process begins. Founder dependency, the degree to which the business runs on your relationships, your judgement, and your presence, is one of the most frequently cited reasons a buyer applies a discount. Compliance risk, particularly around data protection under UK GDPR and AI governance under ICO guidance, creates contingent liabilities that reduce deal certainty or trigger indemnity clauses. And cyber posture matters: the National Cyber Security Centre urges UK SMEs to follow its 10 Steps to Cyber Security framework, and weak controls raise both breach risk and insurance costs that buyers factor into their pricing.
The cleaner the EBITDA story, and the more predictable the earnings look to a buyer, the more confidently they apply the multiple you are hoping for. That confidence is what the 12 to 36-month preparation window is actually buying you.
If you want to think through where your business sits against these levers before committing to a timeline, that is exactly the conversation I work through with founders. Book a conversation.
