How Pension Consolidation Calculator works
Impact of fees on pension growth
Annual Management Charges (AMC) compound over time. A 1% higher fee on a £80,000 pot over 20 years at 7% gross growth reduces the final pot by approximately £55,000. Fee differences matter enormously over a full working life.
When to consolidate
Consolidation makes sense when: the new scheme has lower fees, the investments are as good or better, you have many small pots (admin simplicity), and there are no valuable benefits in the old scheme (guaranteed annuity rates, defined benefit elements). Never consolidate a defined benefit (final salary) pension without regulated financial advice.
When NOT to consolidate
Keep pensions separate if any of them have: guaranteed annuity rates (GARs), safeguarded benefits, or defined benefit (final salary) elements. Transferring these away can be very costly. Always check for exit penalties in the current scheme.
HMRC rules on pension transfers
Pension transfers between registered UK schemes are generally free of tax. You can transfer defined contribution pensions without restriction. Transfers of defined benefit (final salary) pensions worth more than £30,000 require regulated financial advice under FCA rules — advisers must assess the transfer value against the projected benefits. HMRC-registered overseas pension schemes (QROPS) can also receive UK pension transfers but may be subject to an overseas transfer charge of 25% in some circumstances.
The Pension Tracing Service and lost pensions
There are an estimated 3 million lost pension pots in the UK, worth approximately £26 billion in total. The government's free Pension Tracing Service (gov.uk/find-pension-contact-details) helps you track down pensions from former employers using the employer's name. Once found, contact the scheme administrator with your National Insurance number and dates of employment. The government's Pensions Dashboard — being rolled out from 2025 — will allow you to see all your pension entitlements in one place for the first time.

Frequently asked questions
Should I consolidate my pensions?
Usually yes, if the new scheme has lower fees and no valuable guaranteed benefits are lost. Use the Pension Tracing Service (gov.uk) to find old pensions. Never consolidate a final salary (DB) pension without taking regulated advice.
How do I find my old pensions?
Use the government's Pension Tracing Service at gov.uk/find-pension-contact-details. You need the employer's name. Most pension providers will locate your old pension from your National Insurance number and date of birth.
How much does annual fee difference matter?
Very significantly over long periods. A 0.5% lower AMC on £80,000 over 20 years at 7% growth saves approximately £28,000. Even on smaller pots, lower fees compound dramatically over a 30–40 year working life.
Can I consolidate a final salary pension?
You can transfer a defined benefit (final salary) pension to a defined contribution scheme, but if the transfer value exceeds £30,000 you are legally required to take regulated financial advice first. FCA rules are strict because final salary pensions offer guaranteed income for life that is very hard to replicate in a DC scheme. Most advisers recommend against transferring final salary pensions unless there are exceptional circumstances.
Are there tax implications when consolidating pensions?
No — transfers between registered UK pension schemes are entirely tax-free. You do not pay income tax, capital gains tax, or any other charge when moving pension pots between providers. However, if you consolidate into a scheme with a protected pension age (allowing access before 57 from 2028) you may lose that protection. Check the terms of both schemes before transferring.
How do I find old pension pots I have lost track of?
The government's Pension Tracing Service (gov.uk/find-pension-contact-details) can help you locate the contact details for workplace and personal pension schemes. You provide the employer or scheme name, and the service returns the scheme administrator's contact details. From there, you contact the scheme directly with your personal details to locate the pension. The Unclaimed Assets Register may also help with very old schemes.
Are there any pensions I should not consolidate?
Yes. Defined benefit (final salary) pensions are almost always worth keeping — they provide guaranteed income for life and typically cannot be replicated by a personal pension. Transferring out of a DB scheme requires regulated financial advice if the transfer value exceeds £30,000. Pensions with guaranteed annuity rates (GARs) — common in older policies — can be extremely valuable and should not be transferred without specialist advice. Check for any protected tax-free cash entitlements above 25%.
How long does pension consolidation take?
A straightforward transfer between modern pension platforms typically takes 4-8 weeks for in-specie (investment) transfers and 2-4 weeks for cash transfers. Older workplace schemes can take 3-6 months. Defined benefit transfers require additional steps including an actuarial valuation and regulated advice, which can take 3-6 months. Your new provider should manage most of the process on your behalf.
Will I be out of the market during the transfer?
During a cash transfer, your investments are sold in the old scheme and repurchased in the new scheme — you are out of the market for the period between selling and reinvesting. In-specie transfers move investments directly without selling, but not all schemes support this. To minimise market exposure during cash transfers, some providers allow you to remain invested until the transfer completes and then move to cash only for the settlement period.
Does consolidating pensions trigger a tax event?
No — pension-to-pension transfers are not taxable events and do not trigger income tax or capital gains tax. The transfer simply moves the pot from one registered pension scheme to another. However, if you take any benefits (tax-free cash or income) during the transfer process, those are taxable in the normal way. Unauthorised transfers — for example, to schemes that are not registered with HMRC — can trigger a tax charge of up to 70%.
