In-Depth Guides for UK Investors

Guides and analysis for UK investors — ETF look-through, ISA/SIPP strategy, portfolio tracking, and more.

Written by Archie Roberts, Founder, InvormedLast updated

Invormed publishes practical, opinionated writing for self-directed UK investors. Most of our readers hold investments across more than one platform — a Hargreaves Lansdown SIPP opened years ago, a Vanguard ISA added later for low-cost index funds, perhaps a Trading 212 account or an Interactive Investor GIA on top. Our articles tackle the questions that only become visible once you try to look at all of those accounts together.

Expect three kinds of writing. Practical guides walk through CSV exports, ISA / SIPP / GIA tracking, ETF look-through analysis, and how to combine holdings from HL, AJ Bell, Interactive Investor, Vanguard, and Trading 212 into a single coherent view. Comparisons put UK portfolio trackers — Sharesight, Stockopedia, Morningstar X-Ray, broker in-platform tools, and Invormed — next to each other honestly, including where each tool falls short. Platform deep-dives go inside individual brokers and tools to explain exactly what they do and do not do for a UK investor's tax wrappers.

A consistent theme runs through everything we write: UK retail investing has a visibility problem. Each platform shows you its own slice. Each ETF hides dozens or hundreds of underlying companies. CGT, dividend allowances, and wrapper-specific rules add another layer that most generic tools ignore. These articles exist to close that gap — to help you see your portfolio as it actually is, across every wrapper and every underlying holding, and to make better-informed decisions as a result.

New articles publish regularly. If there is a UK-specific portfolio question you would like covered — a broker we have not compared, a tax wrapper edge case, a platform export quirk — get in touch and we will consider it for a future piece.

Common questions

What is an ISA?

An Individual Savings Account is a UK tax wrapper that lets you invest up to £20,000 each tax year (2026/27) with no tax on dividends, interest, or capital gains. The Stocks and Shares ISA is the most relevant for self-directed investors holding equities and ETFs.

How do I track my ISA, SIPP and GIA in one place?

Most UK brokers only show you their slice of your portfolio. Aggregation tools pull data across providers either via Open Banking AISP feeds, broker CSV exports, or manual entry. Sharesight, Snowball Analytics, and Invormed approach this differently — see the comparison articles in this index.

What is ETF look-through?

Look-through means seeing the underlying stock-level holdings inside an ETF, not just the ETF ticker. It matters because most UK investors hold multiple ETFs (e.g. VWRL + VUSA + a tech sector ETF) that overlap heavily on the same companies — without look-through, you may have 12% Apple exposure without realising it.

What are the tax implications of holding investments in a GIA?

A General Investment Account (GIA) is unwrapped — capital gains above the £3,000 annual allowance (2026/27) are taxed at 18% or 24%, and dividends above the £500 allowance are taxed at 8.75%/33.75%/39.35% depending on income band. Holding the same investments in an ISA or SIPP avoids these.

Are these articles financial advice?

No. These are educational and comparison pieces written for UK self-directed investors. Nothing in this index constitutes financial advice. For personalised guidance, consult an FCA-authorised financial adviser.
