Pay for it

Every promise has a price tag. Pick one, then decide how to pay for it: raise a tax, cut spending, or borrow. The sums are done as you choose.

Every promise we track that has a yearly cost to the public purse, from any party.

Better flood protection for 200,000 properties by 2029

“To ensure the nation is more resilient to flooding, the government is investing £4.2 billion between last April and March 2029 to repair and replace existing defences and construct new ones, with hundreds of projects set to be completed. The new target for 200,000 properties to benefit from this investment will deliver a total economic benefit of £27.9 billion in avoided damage as communities gain better protection and growth is delivered in every postcode.”

How it works

The cost

Each pledge's yearly cost comes from its promise card: the central figure, who made it (a government department, the party itself or an independent body) and a range. Where the source gives one figure, the card adds our usual editorial band and says so.

A tax

HMRC publishes what 1p on income tax or National Insurance, or 1 point on VAT or corporation tax, raises in a year. Its figure for 2026-27, from the edition published 24 Jun 2025, is the one on our tax cards. We divide your share of the cost by it to get the change needed, often a fraction of a penny. Capital gains tax is left out: HMRC says its figures cannot be scaled, and a rise raises little or loses money in its first year.

A cut

A cut comes from one area of spending in the Statement for 2025-26, the latest full year, or from every area by the same share. Debt interest is left out, because it follows interest rates and the size of the debt, and so are accounting adjustments, which are not a service.

Borrowing

Whatever a tax or a cut does not pay is borrowed. Borrowing is what the state spends less what it takes in, so the Statement balances in every plan: income plus borrowing equals spending.

Ranges

The pledge's cost and the tax's yield are each uncertain, so the change in borrowing runs from the cheapest pledge with the best yield to the dearest with the worst. A cut is a decision about money already counted, so it is exact.

Questions

Is this what the government will do?

No. It is a what-if: one pledge, paid for one way, on official figures. A real Budget pays for many things at once and the Office for Budget Responsibility checks the sums. Where a pledge said how it would be paid for, the page shows that too.

Why does a tax need only a fraction of a penny?

Because a penny on a big tax raises billions. HMRC's figure for 1p on the basic rate of income tax is several billion pounds a year, so a pledge costing a few hundred million needs a small fraction of that. Tax rates are usually set in whole pence; the fraction shows the scale.

Why does borrowing still show a range when the pledge is paid for in full?

The pledge's cost and the tax's yield are both estimates. If the pledge costs more than expected and the tax raises less, the gap is borrowed; the other way round, borrowing falls. The range shows both ends.

Which pledges are here?

Every promise card with a yearly cost to the public purse, from any party, in government or not, under the same rules. Pledges that raise money, such as a new tax, are not listed, because they need no paying for. They are on the promise ledger.

Does a tax rise or a cut change how the economy behaves?

HMRC's figures include how taxpayers respond, such as reporting less income, but not wider effects on prices, jobs or growth. Cuts are counted pound for pound. The sandbox on the home page shows rough effects on prices and growth, as wide ranges.

Who decides each of these?

Taxes, spending and borrowing are decided by the government and voted through by Parliament. The interest on borrowing depends on Bank Rate, which the Bank of England sets, and on the markets.
