Income for life, without the worry.

A smarter way to draw your retirement income — one that flexes with the markets, so a downturn need never cut your lifestyle, and the good years are there to be enjoyed.

1

A flexible income

Not a rigid 4% rule. We set upper and lower guardrails around your pot and act only when they are reached.

2

An income buffer

18 months of income, set aside from day one. When markets fall, your income is paid from the buffer — your budget never feels it.

3

Enjoy the upside

When markets rise past the upper rail, we refill the buffer and give you a step‑up in income, or a lump sum to spend.

Important. The value of investments can fall as well as rise and markets will vary — you may get back less than you invest. This guide is for illustrative purposes only and is not financial advice. In our experience, the keys to success are working directly with a financial planner and holding a high‑quality underlying investment solution.

How do you draw an income in retirement that lasts — without running out of money, or dying with far too much still in the bank? This is the thinking behind the Becketts Guardrail Strategy. Step through it below.

The three building blocks

1 · Bengen's safe rate

Nearly 20 years of UK and US data set a "safe" withdrawal rate of about 4% on a balanced portfolio — closer to 3.7% in the UK. A useful backstop, but a worst-case, one-size-fits-all rule.

2 · Guyton-Klinger guardrails

Jonathan Guyton and William Klinger modelled raising income with inflation and reacting to market shocks, setting guardrails around spending. Powerful — but a pure model keeps pushing risk up with age.

3 · The Becketts buffer

We combine both with how people actually feel. An income buffer fund of 18 months' income means a market fall need never cut your income — and good years fund real enjoyment.

How the rules work
Starting withdrawalAround 4% of the starting pot if you want to keep your capital secure.
Upper & lower guardrailsSet 15–20% above and below the starting capital. On a £1,000,000 pot, that is roughly £1,150,000–£1,200,000 and £800,000–£850,000.
Income buffer fund18 months of income set aside at outset (on £40,000 a year, that is £60,000). It exists to pay your income when markets fall.
Lower rail breachedPortfolio withdrawals pause; your income is paid from the buffer instead, leaving the pot to recover. Your monthly income does not change.
Upper rail breachedTop the buffer back up, then either take a lump sum to spend, or move the rails up for a step-increase in income.
ReviewThe plan runs continuously; we act when a guardrail is reached, not on a fixed calendar.
