Do you need a financial adviser for a large cash lump sum?
The first decision after receiving a large lump sum does not have to be an investment decision. Work out what the money needs to do first.

You do not have to invest immediately
A large cash balance can create pressure to act quickly. It can be reasonable to separate short-term commitments, tax or known spending from money intended for long-term goals before deciding how much investment risk to take.
Why did the money arrive?
An inheritance, business sale, redundancy payment and property sale can create very different planning needs. The source of the money often changes tax, time horizon and emotional considerations.
When might advice be useful?
Compare service and fee structure carefully
Large portfolios can make percentage-based advice expensive in cash terms. Ask about tiers, caps, fixed-fee alternatives and what ongoing work is actually included.
Establish which part of the cash is genuinely available
A lump sum can arise from a sale, inheritance, compensation, savings or another event. Identify ownership, tax or legal obligations and any conditions before treating the whole balance as available for investment. Keep records of the source and any calculations still to be confirmed.
Separate money for near-term commitments from money for longer-term goals. A planned house purchase, tax payment or business investment can have a timetable that does not suit exposure to short-term market losses.
Ask about the protection and access terms of temporary cash holdings using current official information. A large bank balance is not a reason to rush into a product you do not understand.
Use a purpose-based decision list
Write down the jobs the money needs to perform, the approximate amounts and the dates. Some may be clear; others may need discussion. The adviser can then assess the trade-offs and suitability of arrangements rather than start with a preferred product.
For an invented example, £300,000 received might include £50,000 of confirmed commitments and a possible £80,000 purchase. The remaining planning decision differs depending on whether that purchase goes ahead. A staged assessment can acknowledge the uncertainty without pretending every pound has the same horizon.
Ask what happens if the plan changes. Access restrictions, exit costs and tax consequences can matter as much as a projected return.
Compare advice and implementation costs separately
Request the planning fee, any investment implementation charge and normal ongoing costs. Ask whether the firm can provide a plan without requiring all the money to be managed under one recurring service.
Do not assume that taking more investment risk is necessary simply because cash interest may change. The appropriate risk relates to the purpose and consequences of loss. Equally, holding cash indefinitely has its own purchasing-power considerations. A personal assessment should make those trade-offs explicit.
Keep the final plan and assumptions, and agree which events would trigger a review. The aim is a considered use of the money, not rapid completion of an investment application.
