Choose a gilt platform by comparing dealing costs, custody fees, available gilts, execution method and ease of holding to maturity. Then choose nominal or index-linked gilts based on the risk your plan is trying to hedge, not because one type recently performed better.

What a gilt is

A UK gilt is a UK government debt security. When you buy one, you are lending to the UK government under the bond's terms. The gilt has a coupon structure and a maturity date, and its market price can rise or fall before maturity.

That last point is crucial. A gilt held to maturity has a different risk profile from one sold before maturity. If market yields rise after you buy, the market price of an existing fixed-coupon gilt can fall.

What to compare on a platform

The platform should not be chosen only by its advertised dealing fee. Check whether it offers the exact gilt or gilt type you need, what the custody charge is, how orders are executed, the minimum trade size, how interest is credited and how easy it is to sell.

If you are building a ladder with several maturities, the dealing process matters. A £10 transaction fee that seems small once can become significant when repeated across many purchases.

A gilt ladder matches cash needs to maturities

A ladder spreads purchases across maturity dates rather than putting all the money into one bond. The idea is to have different pieces mature in different years, creating a series of known dates when principal can be redeployed or spent.

A ladder is not a guarantee against loss. Market values still move before maturity, and reinvestment risk remains because future interest rates will not be known when each rung matures.

Nominal versus index-linked gilts

Nominal gilts make fixed coupon and principal payments according to their terms. Index-linked gilts adjust relevant payments with inflation-linked measures under the gilt's rules. That can make index-linked gilts useful when the spending goal is sensitive to inflation.

The trade-off is complexity and different price behaviour. A higher inflation-adjusted protection can be valuable, but the market price of an index-linked gilt can still move materially and short-term performance can be unintuitive.

Should you delay a gilt ladder?

Trying to wait for the perfect entry point is still market timing. If the ladder exists to match known liabilities, buying according to the liability schedule can be more robust than repeatedly delaying because yields might move. You can also stage purchases if that helps with cash-flow management, but the key is that the ladder should serve the liability plan.

Gilts explained simply

Imagine lending the government £100 under a written promise: it will pay you set amounts while the loan is outstanding and return the principal according to the security's terms. If you want to sell that promise before the end, its market price can change because new loans may offer more or less attractive terms.

Tax and holding structure

Tax treatment depends on the type of account and security. GOV.UK explains capital gains tax generally, while the specific tax treatment of gilts can depend on the gilt and investor circumstances. Use a current HMRC or adviser source for the exact transaction rather than assuming every bond has identical tax treatment.

A better platform checklist

Can it trade the actual gilt or gilt type?
What is the dealing spread or fee?
Is there a custody or account charge?
How are coupons paid and recorded?
Can you sell easily if your plan changes?
Are the account and tax wrappers suitable?

For a long-term ladder, low friction and accurate execution can matter more than a headline rate on an unrelated cash product.

Worked example

Illustrative example: Emma wants £30,000 of future spending to mature in three different years. She considers buying three gilts of roughly £10,000 each rather than putting all £30,000 into one maturity.

Rung 1 target: £10,000.
Rung 2 target: £10,000.
Rung 3 target: £10,000.
Math: £10,000 + £10,000 + £10,000 = £30,000.

Emma compares platform dealing costs and the maturity dates against her spending plan. She does not choose nominal or index-linked status because of last year’s performance; she chooses the structure that matches her liabilities and inflation risk.

The figures are illustrative and are included to show the decision process; the real outcome depends on the actual contract, provider rules and personal circumstances. A real transaction may also involve fees, spreads, tax treatment or timing differences that are not included in the simplified example.

Which platform is best for buying gilts?#

The best platform depends on the exact gilts you want and how often you trade. Compare dealing fees, custody charges, execution, minimums, availability and ease of selling. A platform that is cheap for one trade may be expensive for a multi-rung ladder.

Should I delay buying a gilt ladder?#

Only if the delay serves a cash-flow or risk-management reason you can explain. Waiting because you hope yields will move in your favour is market timing. If the ladder exists to match future spending, a planned schedule can be more useful than guessing the next interest-rate move.

When should I use index-linked gilts?#

They can be useful when your spending or financial plan is particularly sensitive to inflation and you understand how the specific index-linked gilt works. They still have market-price risk and can behave differently from nominal gilts before maturity. Check the provider, lender or regulator for the exact rules that apply to the real transaction.

What are gilts in simple terms?#

A gilt is a loan to the UK government represented by a tradable security. You receive the payments promised by the security and, subject to the terms and holding strategy, principal at maturity. If you sell before maturity, the market price can be higher or lower than what you paid.

Can I buy gilts through a broker?#

Yes. The UK Debt Management Office explains that individual investors can access gilts through intermediaries and the secondary market. Your broker or platform will have its own dealing costs and product availability, so compare the actual service you plan to use.

Is a gilt ladder guaranteed to make money?#

No. A ladder can help match maturities to spending dates, but bond prices move before maturity and future reinvestment rates are uncertain. The return you actually receive depends on the purchase price, coupon, maturity and whether you hold or sell before maturity.

Are gilts the same as cash savings?#

No. A savings deposit is a bank deposit with deposit-protection rules where applicable. A gilt is a marketable government debt security whose price can move. Gilts can be useful for a different role in a portfolio, but they should not be treated as identical to an instant-access savings account.
