What's the difference between AVCs, SIPPs and ISAs?

We know many members ask this question when thinking about how to save more for the future.

Whilst we can’t tell you which option is best for your individual circumstances, we can explain how Additional Voluntary Contributions (AVCs) work in the Railways Pension Scheme, and how these differ from Self-Invested Personal Pensions (SIPPs) and Individual Savings Accounts (ISAs).

These 3 arrangements offer very different ways to save and invest, with different tax rules and levels of access.

Additional Voluntary Contributions (AVCs)

AVCs are flexible extra pension savings you can make directly from your pay before tax is taken, on top of the normal pension contributions.

In the RPS there are 2 AVC arrangements: BRASS and AVC Extra.

BRASS

BRASS is the main arrangement for all active Defined Benefit members and is a great way to boost your retirement income.

It can be particularly useful if you receive additional earnings that don’t count towards your main Scheme pension – for example, overtime or bonus payments.

You can pay as little as £2 per week or £10 per month (if you are paid monthly) on top of your usual pension contributions.

AVC Extra

AVC Extra is available to members who have already reached the maximum they can pay into BRASS and still want to save more. 

You can choose how much you want to pay into AVC Extra, but you should be mindful of tax limits.

Key features of AVCs:

  • Flexible payments - you don’t need to save a fixed amount every month. If expenses go up, you can reduce your contributions, and you can increase them again when things are easier.
  • Good for variable earning - particularly useful for topping up retirement savings from overtime, bonus payments or other non‑pensionable pay.
  • Tax relief on contributions - you’ll get government tax relief on anything you put in, up to your annual allowance - currently £40,000 for most people. If you’re a high earner with an income of more than £200,000 a year, your annual allowance might gradually reduce to as low as £4,000 in the current tax year.
  • Locked until retirement - AVC savings normally can’t be accessed until you reach your Normal Pension Age – currently 55, rising to 57 in 2028.
  • Limited investment choice –  you choose from a pre-selected range of funds supplied by the Scheme’s investment manager, Railpen.

More information on BRASS and AVC Extra is available in the saving more area of this website.

 

Self-Invested Personal Pension (SIPP)

A SIPP is a personal pension you set up and manage yourself, separate from your employer.

You can pay money in regularly or in lump sums, with the aim of growing your pension pot over the long term.

You can choose to manage your own investments or use a financial adviser (usually for a fee).

Key features of SIPPs:

  • Tax relief – you receive tax relief on your contributions at your income tax rate (20%, 40% or 45%). Your contributions taken from your pay after tax, but your provider then claims basic-rate tax relief from the government and adds it to your pension pot.
  • Wider investment choice - you can choose from a much broader range of investments than you can with workplace AVCs
  • You can access the money in your SIPP from the age of 55 (this is due to rise to 57 from 2028). You can take your pension pot either as a lump sum, draw it down gradually or use it to buy an annuity – which will provide you with a regular income.
  • With a SIPP, you have full control over your account - you choose the provider, how much to pay in, and where to invest. You also have the flexibility to transfer to another provider, or to choose when to take them.

Individual Savings Account (ISA)

An ISA is a normal savings or investment account that you can open and pay into.

You pay into it from your after‑tax income, but all the growth, dividends and interest are tax‑free

There are different types of ISA accounts:

  • Cash ISA
  • Stocks & Shares ISA
  • Lifetime ISA (for first home or retirement)
  • Innovative Finance ISA

These are available through banks, building societies and other financial providers.

Key features of ISAs:

  • Tax-free growth - you don’t pay any tax on returns and what you receive is paid to you free of tax
  • No tax relief on contributions - you save from your take‑home pay
  • Flexible access – you can withdraw your money at any time with no penalties (except specific rules for Lifetime ISAs).
  • Annual limit - you can put in up to £20,000 per tax year across all your ISAs combined.

You can find out more about the different types of ISAs and how to manage an ISA account in this blog.
