Chancellor John Healey delivered his first Budget on Wednesday 28 October. For advisers and professional investors, the immediate questions are how the announcements may affect client tax planning and whether they alter the investment outlook. The main measure for savers is a further rise in tax on taxable savings interest and property income from April 2027. The planned cut to the cash ISA allowance has been scrapped, while no new changes to pension tax relief or mainstream capital gains tax rates were announced. In our view, the Budget alone does not warrant a change to a long-term investment strategy.

What was the backdrop?

The Budget came against a difficult economic backdrop. The conflict in the Middle East has pushed up energy prices: UK inflation rose to 3.5% in September, and the Office for Budget Responsibility (OBR) now expects inflation of 3.1% this year and 3.4% in 2027. UK government borrowing costs have climbed to their highest levels in decades, while the Government’s headroom against its borrowing rules has narrowed.

What was announced?

Measure What was announced Who it affects
Tax on savings and property income A further 2 percentage points from April 2027, on top of the 2-point rise announced last year: rates rise to 24%, 44% and 49% for taxable income to which they apply, subject to applicable allowances Savers and landlords
Cash ISA allowance Planned cut from £20,000 to £12,000 scrapped; the announced allowance remains £20,000, subject to applicable ISA rules Cash savers
New "Starter ISA" To be developed with industry for first-time investors; eligibility and other details to follow New investors
Lifetime ISA Proposed replacement by a First Time Buyer ISA. Withdrawal treatment for savers affected by the £450,000 property cap, including the 25% bonus, requires confirmation before publication. First-time buyers
Founders' Relief (new) Proposed 10% capital gains tax rate on up to £10m of lifetime gains for founders of qualifying UK companies from 6 April 2027; subject to consultation Business founders
Bank Surcharge Up from 3% to 6% for 15 months from 1 January 2027, raising about £1.5bn Banks; potentially bank shareholders
OBR forecasts Inflation 3.1% this year and 3.4% in 2027 (March: 2.3% and 2%); growth 1.0% in 2027 (cut from 1.6%) All investors
Public finances Headroom £15bn in 2029/30 (down from £23.6bn); borrowing 4.2% of GDP this year, falling to 1.8% by 2030/31; gilt sales £250.6bn this year Gilt investors

The further 2-percentage-point rise announced for savings and property income would, together with the 2-point rise announced last year, leave the relevant rates 4 percentage points higher from April 2027 than today. The Treasury expects the additional 2 points announced in this Budget to raise about £1.1bn a year by 2028/29. The Budget also stated that, from April 2027, pensioners whose only income is up to the level of the new State Pension will pay no income tax; the scope and operation of this measure should be checked against the final documents. 

There were no announced changes to income tax rates, dividend tax, mainstream capital gains tax rates, pension tax relief or inheritance tax thresholds.

What are the implications for advisers and investors?

ISAs and savings: The announced ISA allowance remains £20,000 a year, available across cash and stocks and shares ISAs, subject to the applicable ISA rules. From April 2027, the announced rates of 24%, 44% and 49% would apply to taxable savings interest where relevant, subject to individual circumstances and any available allowances. That may increase the value of tax-efficient wrappers for some clients, rather than making an ISA the right choice in every case. A proposed 22% charge on interest from cash held in stocks and shares ISAs, and restrictions on transfers to cash ISAs, were also reported to have been dropped; these points require confirmation in the final documents. A new Starter ISA for first-time investors is to be developed with industry, with details to follow.


Pensions: No new changes to pension tax relief were announced in this Budget. Measures announced previously remain relevant: unused pensions will count towards inheritance tax from 6 April 2027, and the minimum age for accessing a personal pension rises to 57 in April 2028. Pensions retain significant tax advantages for many long-term savers, although their suitability depends on individual circumstances and the applicable rules.

Income and dividends: Income tax rates are unchanged and thresholds remain frozen until April 2031. As earnings rise, this can bring more people into higher tax bands. Dividend tax rates rose this April, adding to the case for advisers to consider available ISA and pension allowances as part of broader client tax planning.

Capital gains and inheritance tax: Mainstream capital gains tax rates and the £3,000 annual tax-free allowance are unchanged. The proposed Founders’ Relief would apply a 10% capital gains tax rate to up to £10m of lifetime gains for founders of qualifying UK growth companies from 6 April 2027, subject to consultation. The announcement specifies at least five years’ share ownership and five years’ UK residence; the Government is consulting on the details until 30 November. Inheritance tax thresholds remain frozen at £325,000, plus £175,000 where a main home is passed to children or grandchildren, subject to the relevant conditions.

How did markets react?

Initial market moves on 28 October 2026 were relatively modest, based on mid-afternoon data. The 10-year gilt yield, a measure of UK government borrowing costs, edged down to around 5.32%, about 0.2 percentage points below this month’s peak, the highest since 2007. Longer-dated gilts strengthened after the Debt Management Office said it would sell fewer long-dated bonds, with the 30-year yield falling to just below 5.7%. The FTSE 100 rose 0.3%; Lloyds gained 4.2%, Barclays 3.7% and NatWest 2.4%. Sterling was little changed at around $1.33. These are initial observations rather than evidence of a lasting market response.

How are we assessing portfolios?

Our portfolios are diversified across regions, sectors, asset classes and fund managers with different approaches. Diversification can reduce exposure to a single event, such as a UK Budget, but cannot eliminate investment risk. We are not changing portfolios solely because of the Budget, although positioning remains subject to the mandates and circumstances of individual portfolios. We will be watching energy prices, gilt markets and the Bank of England’s next interest rate decision on 5 November. Higher gilt yields can increase the starting income available from newly purchased bonds, although bond prices may remain volatile while inflation is high. We will continue to assess developments through our established investment process rather than react to short-term headlines.

The long-term investment perspective

In our view, the Budget provides some clarity on the measures announced today, while energy prices, inflation and the path of interest rates remain important for investors. Advisers may wish to review affected clients’ use of ISA and pension allowances, the real value of cash holdings and, where relevant, estate plans ahead of the April 2027 pension changes. Any action should reflect individual circumstances and the final detail of the announced measures. Advisers and professional investors who would like to discuss the investment implications can contact the Titan Square Mile team.
