Cover You Need If…
Life insurance You have dependents or mortgage
Income protection You have income (almost everyone)
Critical illness Family history or want extra protection

How Much Cover

Critical illness 2-3 years income or mortgage

Typical Costs (30s, non-smoker)

Cover Monthly
£300k term life (25 years) £15-25
Income protection (to 65) £30-50
£100k critical illness £30-50

These costs rise significantly each year you delay.

Tax Efficiency

Maximise Allowances

Allowance 2026/27
Personal Allowance £12,570
ISA £20,000
Pension annual £60,000
CGT allowance £3,000
Dividend allowance £500

If Earning Over £50,270

Marriage allowance If spouse earns less than £12,570
Childcare accounts Tax-efficient

Approaching £100k?

The Personal Allowance trap: lose £1 for every £2 over £100k = 60% effective marginal rate.

Solution: Pension contributions above £100k income.

Pension pots Current value
ISAs Current value
Other savings All accounts
Other investments Shares, etc.
