How to Review Your Investment Portfolio Every Year

Why an Annual Review Matters

Successful long-term investing requires a balance between set-and-forget simplicity and occasional deliberate attention. A once-yearly portfolio review allows you to verify that your investments remain appropriate for your goals, rebalance if your allocation has drifted significantly, contribute additional allowances before the tax year end, and make any strategic adjustments prompted by life changes. Done properly, the annual review takes a couple of hours and provides confidence that your financial plan is on track without requiring constant attention to markets.

When to Do Your Annual Review

The UK tax year ends on 5 April each year. Scheduling your annual review in February or March — six to eight weeks before the year end — allows time to top up your ISA allowance if unused, claim higher-rate pension tax relief via self-assessment before the deadline, make any Bed and ISA transfers before your remaining CGT allowance refreshes, and identify any tax-loss harvesting opportunities before the year end. Doing it in January avoids the pre-deadline rush and gives you maximum time to act on any findings.

Step 1: Check Your Asset Allocation

Compare your current portfolio's asset allocation — the percentage split between equities, bonds, and other asset classes — with your target allocation. After a year of strong equity performance, you might find you are running 85 per cent equities against a 75 per cent target. After a market correction, you might find you are underweight equities. Note the degree of drift and whether it is significant enough to warrant rebalancing. A 5 percentage point drift from target is often used as a rebalancing threshold.

Step 2: Check Your Investment Costs

Review the OCF of each fund in your portfolio and the platform fees you paid in the past year. Are there equivalent lower-cost alternatives that would improve your net returns? Has your platform changed its fee structure in ways that make an alternative more competitive at your portfolio size? Even a 0.1 per cent reduction in annual fees translates into meaningful additional wealth over a 20-year period.

Step 3: Assess Progress Towards Your Goals

Review your financial goals and check whether you are on track. If your goal is to accumulate £300,000 for retirement in 15 years, what does your current portfolio value and contribution rate suggest your trajectory is? Use an investment return calculator — Vanguard's and MoneySavingExpert both offer free tools — to project where you will end up given current conditions. If you are behind, consider how you might increase contributions or adjust your timeline.

Step 4: Review Life Changes

Personal circumstances change, and your investment strategy should evolve accordingly. Marriage, children, divorce, significant income changes, purchasing a property, or approaching retirement all affect the appropriate risk level, account types, and investment strategy. Use the annual review to ask whether your current approach still reflects your current life situation and goals.

Step 5: Use Remaining Allowances

Before 5 April, ensure you have used your annual ISA allowance — up to £20,000 for adults and £9,000 for children via the Junior ISA. Make any additional pension contributions to claim available tax relief. If you have a Lifetime ISA and are eligible, contribute up to £4,000 to claim the 25 per cent government bonus before the year end. These allowances reset each year — unused capacity is permanently lost.

Keeping the Review Simple

The annual review should not become an opportunity to overthink or overhaul your strategy. If your allocation is within 5 percentage points of target, your funds are low cost, and your contribution rate is on track for your goals, very little action may be needed. The goal is confidence and control — not constant change. The best investment portfolios are usually ones that are simple enough to understand, set up automatically, and require only occasional maintenance.
