Not legally, but most owners benefit from one. An accountant and solicitor handle the deal’s tax and legal mechanics; a financial planner answers the bigger question, whether the sale actually funds the life you want, how to invest the proceeds, and how to manage tax on a suddenly larger estate. The best outcomes coordinate all three.
The short answer
- You are not legally required to use a financial adviser, but most owners benefit from one.
- An accountant and solicitor handle the deal’s tax and legal mechanics.
- A financial planner answers whether the sale funds your life, and manages the proceeds afterwards.
You are not legally required to use a financial adviser to sell your business, plenty of owners complete a sale with just an accountant and a solicitor. But “can you” and “should you” are different questions. For most owners a financial planner earns their fee many times over, because they answer the question the deal team does not: what does this sale mean for the rest of your life? This is general information, not personal advice.
It helps to see selling a business as two connected projects. There is the transaction, valuing, marketing, negotiating and drafting the deal, and there is your personal financial future, which the transaction is meant to secure. Different professionals lead on each, and the best results come from them working together rather than in isolation. The mistake many owners make is to assemble a strong deal team, complete the sale, and only then start thinking about what to do with the money, by which point several of the most valuable planning options have already closed off.
Who does what in a business sale
The professionals around a business sale
| Professional | What they do | When they lead |
|---|---|---|
| Accountant | Deal tax, structuring, due diligence on the numbers | Before and during the transaction |
| Solicitor | Contracts, warranties, legal due diligence | During the transaction |
| Corporate finance / broker | Valuation, marketing, finding and vetting buyers | Running the sale process |
| Financial planner | Whether the sale funds your life; investing the proceeds; estate and pension planning | Before the sale and long after |
The accountant, solicitor and broker are focused on getting you the best deal on the day. The financial planner is focused on you, before completion, they model whether the price will actually fund the retirement you want, as we set out in the business exit planning guide; after completion, they turn the lump sum into durable income and manage the tax that follows. Crucially, they are the only one of the four whose relationship with you is meant to last for decades, long after the deal team has moved on to their next transaction. That long horizon changes the advice: a planner is not trying to close a deal, but to make the proceeds last a lifetime.
Where a planner adds the most value
A good financial planner earns their keep in the areas a deal team rarely touches:
- Answering “is it enough?”, stress-testing whether the net proceeds will fund your desired lifestyle for life, long before you accept an offer.
- Investing the proceeds, building a diversified plan across pensions, ISAs and other investments rather than leaving a fortune in cash losing value to inflation.
- Managing the tax that follows, a sale often replaces an inheritance-tax-relieved business with cash in your estate, so inheritance tax planning suddenly matters.
- Timing pension contributions, using your £60,000 annual allowance and carry-forward around the sale to shelter proceeds tax-efficiently.
- Coordinating the team, making sure the deal is structured with your whole financial picture in mind, not just the headline price.
The proceeds are the point
It is easy to obsess over squeezing the last few percent out of the price and forget that the proceeds have one job, to fund the rest of your life. A planner keeps that goal in view, which is often worth more than a marginally higher offer that is poorly structured or badly invested afterwards.
Is it worth the fee?
Ongoing advice typically costs around 0.5% to 1% of the invested assets a year, and some planners charge a fixed fee for the exit-planning work itself. On a seven-figure sale, that is a modest fraction of the tax and investment returns in play, and the questions of whether to sell at all, how to structure it, and what to do with the money afterwards are exactly where good advice pays for itself. Our answer on whether a financial adviser is worth it looks at the trade-off in more depth, and how to choose an adviser explains what to look for.
The key is to engage a planner before you go to market, not after the money has landed, so the deal is shaped around your goals from the start. A planner brought in early can influence how the price is split between cash and deferred payments, how much you contribute to a pension in the run-up, and whether a spouse should hold shares, decisions that are impossible to revisit once contracts are signed.
