When you trust a financial provider with your money, especially your pension, you expect clarity, accuracy, and accountability.
Unfortunately, that wasn’t my experience when I transferred my SIPP from Vanguard to InvestEngine. What should have been a straightforward transfer turned into nearly six months of delays, missing funds, and miscommunication.
In this blog post, I’ll walk you through the full journey, from raising a complaint to getting a resolution through the Financial Ombudsman.
Whether you’re facing a similar issue or just want to understand your rights, this step-by-step guide will help.
What Is the Financial Ombudsman Service?
The Financial Ombudsman Service (FOS) is a free, independent service set up by the UK government to resolve disputes between consumers and financial businesses. You can complain about banks, pension providers, investment platforms, insurance companies, and more.
If you’ve complained to a financial firm and they haven’t resolved it within 8 weeks (or their final response isn’t satisfactory), you can escalate your case to the Ombudsman.
What I Was Dealing With
In December 2024, Vanguard announced a structural change in their fees: from 31 January 2025, customers with combined Vanguard accounts valued under £32,000 would be subject to a £4 monthly account fee (i.e. £48/year).

Before this change, Vanguard applied a 0.15% annual account fee (capped at £375).
Because my SIPP fell under that threshold, the new fixed fee would disproportionately affect my returns, especially on a smaller balance. So, I decided to move to InvestEngine, which offered a fee structure that (at the time) seemed more favourable for smaller portfolios.
But what followed was months of back and forth:
- Conflicting information about missing cash
- Delays in initiating the transfer
- Poor communication from both parties
- Emotional stress and wasted time trying to trace my money.
Eventually, I had to raise formal complaints with both platforms.

🧭 Why I Chose to Transfer
I’ve always been an advocate for Vanguard due to their low fees and solid index fund choices. But once my pension pot dropped below £32,000, I reconsidered the fees in proportion to my balance.
As a financial coach, I’m passionate about reducing hidden investment costs, and the InvestEngine SIPP, with zero platform fees for ETFs, seemed like a sensible switch.
Unfortunately, this was the start of a long and stressful journey.
🧨 Where It All Went Wrong
The transfer didn’t go as expected.
InvestEngine initially stated that they’d received all the funds, but I noticed a significant shortfall. Vanguard told me everything had been sent. Later, they claimed the missing funds were still invested in two funds.
Eventually, Vanguard acknowledged the mistake and sent the rest, but by this point, months had passed.
Meanwhile, InvestEngine delayed initiating the transfer for four weeks and failed to follow up on the missing funds. It took multiple emails from me just for them to understand the complaint.

Step-by-Step: How to Raise a Complaint to the Financial Ombudsman
If you’re in a similar situation, here’s the exact process I followed:
Step 1: Complain to the Company First
Before the Ombudsman can step in, you must complain directly to the business. They have up to 8 weeks to respond.
Tip: Always submit your complaint in writing and request confirmation of receipt. Be clear, concise, and include dates and evidence.
Step 2: Wait for Their Final Response (or 8 Weeks)
- If they resolve your complaint, great.
- If they reject it or don’t respond within 8 weeks, you can escalate to the Ombudsman.

Step 3: File Your Complaint With the Financial Ombudsman
You can complain via:
- Their website
- Email: [email protected]
- Post
You’ll need:
- A clear summary of your complaint
- A copy of the final response letter (if available)
- Supporting documents (e.g., emails, screenshots, statements)
Step 4: Case Is Assigned to an Investigator
An investigator will contact you. Be honest, clear, and cooperative. They will also contact the business.
My Experience: The Outcome
InvestEngine:
- Initially misunderstood my complaint (they mentioned an ISA instead of a SIPP!)
- Took no real action until the Ombudsman got involved
- Only then offered a goodwill payment of £100, blaming Vanguard
- After my rejection, Ombudsman negotiated a final offer of £200, which I accepted
Vanguard:
- Initially said all funds were sent or lost due to market performance
- After my complaint, they investigated thoroughly
- Eventually identified delayed fund sales as the issue
- Credited the missing amount to my pension and paid £250 as goodwill
- I requested an increase to £500 due to the stress and disruption – this is still under review
Key Lessons and Takeaways
- Fees Aren’t Everything: While I moved for lower fees, the stress and delays taught me to also value service quality.
- Document Everything: Emails, screenshots, dates – all of it helps support your case.
- The Ombudsman Works: It took time, but I got results. Don’t give up.
- Raise Concerns Early: Don’t wait until the situation escalates – flag discrepancies immediately.
Not All Insurance Complaints Are Eligible: Here’s What Happened to Me
Quick Tip:
Only insurance providers regulated by the Financial Conduct Authority (FCA) fall under the Financial Ombudsman Service.
Unfortunately, not all companies that look like insurers are regulated insurers.
Take my recent experience with a company called Domestic Appliance Guard. I paid for cover on my home appliances, including my oven. When my oven broke, their engineer confirmed it was repairable. However, the company refused to fix it and instead offered a small settlement of £35.80, despite the fact that I ultimately had to pay over £400 to replace it.
When I tried to escalate the issue, I was told that they are not a regulated insurance firm and, therefore, not covered by the Financial Ombudsman. They even tried to enforce an automatic policy renewal.
📞 After multiple ignored emails, they kept calling, and only backed down after my husband called to reject the auto-renewal.
⚠️ Lesson learned:
Just because something sounds like insurance doesn’t mean it is.
✅ Always check if the company is FCA regulated before buying a policy, especially with appliance cover, extended warranties, and home emergency services.
Who Can You Complain About?
You can raise complaints to the Financial Ombudsman about:
- Banks and building societies
- Pension providers and administrators
- Investment firms
- Insurance companies
- Loan providers and credit card issuers

🚫 But be cautious:
- Not all extended warranty or appliance cover firms are regulated.
- Always check the firm on the FCA Register before buying cover.
