Frequently asked questions

When should I start retirement planning?

As early as possible. £100/month invested from age 25 typically results in £150,000-£200,000 by 65. £100/month from age 45 typically results in £30,000-£40,000.

How much should I save for retirement?

A common UK guideline is 15-20% of gross income including employer contributions. If starting late, higher.

Should I use an adviser?

Depends on complexity. For straightforward DC + ISA + SIPP, self-directed works. For DB transfers, business exits, complex tax situations, an FCA-authorised adviser is valuable.

What's the ideal retirement income?

Traditionally 60-70% of pre-retirement income. Depends on housing costs (mortgage-free?), health, and lifestyle choices.

Can I retire at 55?

Yes if you can access pension money at 55 (57 from 2028) and have sufficient savings. But retiring at 55 with 35+ year expected lifespan requires substantial pot — often £1M+ for comfortable income.
