The pieces we think are worth your half-hour right now.
Mortgage rate cuts vs the 6% reality
Santander, Halifax, BM Solutions and Nationwide all cut rates this week. So why is the average 2-year fix still around 5.78%? UK gilt yields hit 17-year highs and that is where the answer lives.
Read the guide →Premium Bonds rise to 3.8% from July
NS&I’s prize rate goes up for the first time since November 2023. The expected return is now back above easy-access cash ISAs — but the median holder still wins nothing. Whether the rebase actually changes the maths.

- Annuities in 2026: How They Work and Whether They’re Finally Worth It (UK)
After years out in the cold, annuities are back: UK rates hit 18-year highs in 2026, letting a healthy 65-year-old turn a £100,000 pension into around £7,800 of guaranteed income for life. But an annuity is a permanent decision with real trade-offs against drawdown. Here is how annuities work in 2026, the types that matter, the annuity-versus-drawdown question, and who should consider one. - The 22% ISA Cash Charge from April 2027: What It Means for Investment-ISA Savers
From 6 April 2027 a flat 22% charge applies to interest earned on uninvested cash held inside a stocks and shares ISA or innovative finance ISA. It closes the workaround of using an investment ISA as a tax-free cash account, and it sits alongside the £12,000 cash ISA cap as the second anti-circumvention rule in the 2027 ISA reform. Here is who is affected, the money market fund exception, and what to do before April 2027. - UK Bond Consolidated Tape 2026: What the New Real-Time Tape Means for Investors
On 22 June 2026 the FCA switched on the UK’s first real-time consolidated tape for bonds. Here is what it is, why it took so long, and what it changes for ordinary gilt and bond-fund investors. - First Time Buyer ISA 2026: What the LISA Replacement Means for Savers
On 23 June 2026 the government published a consultation on a new First Time Buyer ISA that will, in time, replace the Lifetime ISA. It drops the age-40 limit and the 25% penalty and pays the bonus when you buy. But the bonus rate and the property price cap are still unconfirmed. Here is what is settled, what is still open, and what to do if you already hold a LISA. - When to Claim Social Security: 62 vs 67 vs 70 (2026 Break-Even Guide)
Claim Social Security at 62 and you lock in a permanently smaller check; wait until 70 and every year of delay adds about 8%. The right age is not the same for everyone. Here is the 2026 break-even math, how delayed retirement credits and the earnings test actually work, what your decision means for a spouse, and the handful of questions that decide it. - State Pension Top-Ups 2026: The Voluntary National Insurance Guide
Filling a gap in your National Insurance record can be one of the highest-return moves in UK personal finance: roughly £957 to buy a year that adds about £358 to your State Pension every year for life. But it is not right for everyone, and you must check your forecast before you pay a penny. Here is how voluntary NI works in 2026, the payback math, the six-year deadline, and the traps to avoid.
