Received an Inheritance or Sold a Business? Planning for a Financial Windfall

An inheritance, the sale of a business, a redundancy settlement or a property sale - a significant lump sum is one of the few genuine turning points in a financial life. It is also a moment when expensive mistakes are easy to make, partly because the sums are unfamiliar and partly because windfalls often arrive attached to grief, stress or major life change. This guide covers the sensible first moves and the traps we most often see.

First: do nothing, safely

Very few windfall decisions are urgent. Park the money somewhere secure and accessible while you take stock - and be conscious of the £120,000 per-institution FSCS protection limit: sums above it are safer spread across separate banking groups. (Money from certain life events, including property sales and inheritances, can qualify for temporary higher protection for six months.) Taking weeks or even months to decide costs little; deciding badly in week one can cost a great deal.

The order of operations

Most good windfall plans work through the same sequence, tailored to circumstances:

• Clear expensive debt. Guaranteed, risk-free return.
• Build the buffer. An emergency fund covering several months of outgoings.
• Consider the mortgage - though whether overpaying beats investing is genuinely situational: our guide to overpaying your mortgage versus investing works through it.
• Use the tax shelters. ISA allowances, pension contributions (which attract tax relief and can recover lost allowances via carry forward), and spousal allowances - the difference between sheltered and unsheltered growth compounds enormously over decades.
• Invest the long-term core at a risk level you can actually live with.
• Think about the next generation. Inheritance tax planning is far more effective done early - especially with the April 2027 pension changes altering the landscape.

The traps we see most often

• Lifestyle creep before planning - the windfall quietly becomes the spending baseline.
• Concentration - putting most of it into a single asset, often one buy-to-let property.
• Performance-chasing - investing it all in whatever performed best last year.
• Ignoring tax on the way in - business sales in particular have reliefs and elections with strict deadlines; the planning is best done before completion, not after.
• Unsolicited “opportunities”. Windfalls attract salespeople and, worse, fraudsters. Genuine investments are never marketed by cold call, and the FCA register tells you who is authorised.

Selling a business? Start earlier than feels necessary

If your windfall is a business sale on the horizon rather than money in the bank, the most valuable planning happens twelve months or more before the deal: structuring, pension funding from the company, relief eligibility and the shape of the consideration all have more options while the transaction is still flexible.
