Secure the prize
Finish the claim, tighten your banking and digital security and keep the circle of people who know as small as you want it to be.
You have won a life-changing amount. Once the first excitement settles, the practical questions arrive: where should the money sit, how much can you spend, who should you trust and what should happen to the millions you do not need today? This hub helps you work through those questions in a sensible order.
Do not feel that you have to invest it immediately. First, make sure the prize is secure, decide what you need for the next few years, put realistic figures against the home, travel, family help and lifestyle you actually want, and then look at the money that is genuinely long term.
If you won £20 million, for example, you might decide that £5 million covers your home, family plans, near-term spending and a substantial reserve. You would still have £15 million that needs a long-term job. That is the point where investment and wealth planning becomes useful.
Your investment plan should come after your life plan. Put numbers against the things that matter to you first — housing, work, family, travel, security and the lifestyle you want to maintain — so you know which part of the prize is actually available for the long term.
Finish the claim, tighten your banking and digital security and keep the circle of people who know as small as you want it to be.
Set aside what you may need for planned purchases, everyday life and a reserve so you are not forced to sell investments to pay a bill.
Write down the house, cars, travel, family support and recurring annual costs. The running costs matter just as much as the purchase prices.
If a large sum is still genuinely long term, you can start comparing regulated advisers, solicitors, tax specialists and banking support.
You probably do not want millions sitting indefinitely in one bank account, but that does not mean you should move the whole prize into investments at once. Think in layers: money you need soon, money you may need later and money that can stay invested through market falls.
Money for a house, family commitments and several years of spending should not depend on selling an investment at the wrong moment.
Where can the cash sit safely? →A fortune does not need one heroic bet. Diversification means your future is less dependent on one company, property, market or idea being right.
Read the investment guide →If the aim is to fund your life for decades, work backwards from your real annual spending instead of choosing a return target first.
Managing millions guide →You may not need a large team. Start with the problem in front of you, then find the right professional for that problem. If someone is giving regulated financial advice in the UK, check the firm and its permissions with the FCA before you hand over money or act on recommendations.
Ask how much you can spend, what should remain accessible, what can be invested and whether the advice is independent or restricted. Get the fees in pounds as well as percentages.
Financial advice for lottery winners →A solicitor or tax adviser may become useful for wills, property, businesses, trusts or very large gifts. You can add expertise as your decisions become more complex.
Build the wealth team →You are unlikely to need a formal family office simply because you won a jackpot. It becomes relevant when the assets, businesses, property and family administration become genuinely complex.
Read the family office guide →Your normal current account can receive a large payment, but it is not automatically the right long-term home for a fortune. The important distinction is between convenient banking and legal protection if the institution fails.
Standard protection is £120,000 per eligible person, per authorised firm. Several brands can share one banking licence, so spreading cash across logos does not necessarily spread the risk.
Read the cash safety guide →A private bank may make large payments, security controls and administration easier, but eligible deposits still follow the normal protection rules for the authorised institution.
Read the private banking guide →Your National Lottery win is not subject to UK Income Tax when you receive it. Interest, investment returns, gains, gifts and your estate can create tax questions later.
Read the UK tax guide →You may know immediately that you want to help your parents, children or wider family. The difficult part is choosing an amount, a purpose and a structure that you will still be comfortable with years later.
A trust can help when you need control, continuity or flexibility, but it is not automatically the simplest or most tax-efficient route. The type of trust changes the legal and tax result.
Read the trusts guide →Think about what you want the money to achieve for them before deciding on the number. Security, education and housing support are different goals from handing over unrestricted wealth.
Read the children money guide →You can be generous without becoming the answer to every future bill. Decide your boundaries before requests start setting the plan for you.
Read the family guide →You do not need to blow the jackpot overnight to get into trouble. A handful of expensive decisions, weak controls and permanent annual costs can erode wealth surprisingly quickly.
| Risk | What it could mean for you | A better question to ask yourself |
|---|---|---|
| Rushing into investments | You buy because an adviser, friend or salesperson makes the opportunity sound urgent. | What happens if I wait a month? |
| Putting too much in one thing | One business, property or investment ends up carrying too much of your future. | What happens to my plan if this loses half its value? |
| Making an expensive lifestyle permanent | The purchase price may be manageable while staff, cars, travel and upkeep create a huge annual bill. | What will this still cost me every year in ten years? |
| Becoming the family bank | One-off generosity turns into an open-ended responsibility for other people's spending. | Am I giving once, or taking this bill on forever? |
| Ignoring fees | A small-looking percentage on a multi-million-pound portfolio can become a very large annual cash cost. | Exactly how many pounds will I pay each year? |
| Forgetting tax after the win | The prize itself may arrive without Income Tax, but later income, gains, gifts and estate decisions can be taxable. | What tax could this decision create later? |

Use these as quick answers, then move into the linked specialist guide when the decision needs more detail.
Start by protecting the prize and slowing the decisions down. Work out what you need for the next few years, what you want to spend, who you may want to help and what should remain available before you commit long-term money to investments.
There is no single safe portfolio for every winner. Start with the amount you need in cash, your time horizon, your tolerance for losses, diversification, tax, fees and how much money you can genuinely leave invested when markets fall.
Use appropriately authorised institutions and understand the protection applying to each one. In the UK, standard FSCS deposit protection is £120,000 per eligible person, per authorised firm. Different bank brands can share one authorisation, so check the legal entity rather than the logo.
Do not assume it does. FSCS temporary-high-balance protection is linked to specified qualifying life events, and lottery winnings are not on the published list. Build your initial cash plan around the standard rules unless FSCS confirms otherwise in a specific claim.
Not every prize needs ongoing advice, but a life-changing sum can make regulated advice useful. If you use an adviser, check the firm and its permissions with the FCA and understand exactly what you will pay.
Ask whether the advice is independent or restricted, what products and providers can be considered, what permissions the adviser has and whether their experience fits the work you actually need.
Sometimes. Ongoing portfolio management can be useful when the amount and complexity justify it, but compare total fees, custody arrangements, investment approach and regulatory status rather than relying on the job title.
Not automatically. A private bank can make large payments, security controls, borrowing and administration easier, but private banking does not give you unlimited FSCS deposit protection and its investment service may be restricted.
Usually only when your wealth becomes complex enough to need coordinated investment, property, business, tax, legal and family administration. Many winners can use a smaller group of professionals without creating a formal family office.
It depends on what you are doing. You may need an FCA-authorised financial adviser or wealth manager, a solicitor, an accountant or tax adviser and specialist banking support. You do not need to hire every professional on day one.
A trust can be useful for a clear family or estate-planning purpose, but it is not automatically simpler or more tax-efficient. Trust type, control, beneficiary rights, tax and administration all matter, so take legal and tax advice before creating one.
Yes, but decide whether you want to make an outright gift, pay specific costs or use a longer-term structure. Large gifts can also affect Inheritance Tax planning, particularly if you die within seven years of making them.
Yes. The useful question is how much you want to give without weakening your own plan. Keep records and get tax advice before making very large gifts because exemptions, the seven-year rule and estate consequences can matter.
National Lottery winnings are not subject to UK Income Tax when you receive the prize. Once the money is yours, savings interest, investment income, capital gains and estate or gifting decisions can create tax later.
There is no universal percentage. Keep enough accessible for near-term spending, major purchases and a reserve, while remembering that long-term cash has inflation risk and large balances can exceed deposit-protection limits.
That can simplify your finances and remove interest costs, but it is still a planning decision. Check the mortgage rate, early-repayment charges, how much liquidity you want and what else the money needs to do.
A celebration is very different from committing millions to property, businesses, gifts or permanent annual costs. Give the expensive and hard-to-reverse decisions enough time for the rest of your plan to catch up.
Start with the lifestyle cost rather than a target return. Sustainable spending depends on portfolio size, asset mix, tax, inflation, fees, market returns and how flexible you can be when markets are weak.
Money needed soon may belong in cash even though inflation erodes its spending power. Money you will not need for years can be considered separately, with a diversified long-term plan designed around risk, income and growth.
Common problems include acting too quickly, putting too much into one investment, chasing high returns, ignoring fees, lending informally, letting lifestyle costs become permanent and making tax, legal and investment decisions separately.
Write down what the money must achieve, what needs to stay accessible, what level of loss would make you uncomfortable, who you may support and which decisions can wait. That gives any adviser a much better brief.
