Case Study: GMP Equalisation and Defined Benefit Pension Transfer — When History Complicates Your Options (2026)

When Robert came to us, he had a question that puzzles many people who worked in occupational pension schemes before 1997: “What does GMP equalisation mean for my pension transfer value — and does it change whether I should transfer?”

It’s a question that sits at the intersection of four decades of pension legislation, a landmark court ruling, and the very personal question of how best to fund retirement. This case study walks through how we helped Robert understand his options.

Robert’s Background

Robert, 61, worked for a large manufacturing company in the West Midlands for 22 years between 1985 and 2007, before moving to a smaller employer with a defined contribution (DC) scheme. He took early redundancy from that role in 2024 and has been working part-time as a consultant since.

His pension picture at the point of our initial consultation:

• Deferred DB pension (former employer scheme): £10,400/yr payable from age 65 (normal retirement date). The scheme was contracted out of SERPS between 1985 and 1997, meaning it includes a significant Guaranteed Minimum Pension (GMP) component.
• SIPP: £67,000 accumulated from DC contributions with later employers
• ISA: £28,000 in a stocks and shares ISA
• State Pension: Forecast at £9,800/yr (below full new State Pension of £11,502; some pre-2016 contracted-out deduction applies)
• Cash Equivalent Transfer Value (CETV): £218,000
• Spouse: Wife “Sandra”, 59, teacher with Teachers’ Pension Scheme (TPS) entitlement

What Is GMP Equalisation — and Why Does It Matter?

The Guaranteed Minimum Pension was introduced to allow employers to “contract out” of SERPS. In exchange for lower National Insurance contributions, the pension scheme promised to pay a minimum pension that replaced the SERPS benefits that wouldn’t be earned during contracted-out service.

However, there was a historic inequity: men and women had different GMP accrual rates and different GMP payment ages (60 for women, 65 for men). This reflected the different State Pension ages at the time — but it meant that, for equal service, men and women often received materially different benefits from the same scheme.

In November 2018, the High Court ruled in Lloyds Banking Group Pensions Trustees Ltd v Lloyds Bank plc that this difference breached the equal treatment provisions in European law. Schemes were required to equalise GMP benefits — in practice, bringing men’s GMP entitlements up to the equivalent women’s benefit for the years where the gap existed (broadly, service from May 1990 to April 1997).

For Robert, this mattered in two concrete ways:

1. His pension entitlement may increase. If his scheme had not yet completed GMP equalisation, his deferred pension of £10,400/yr might be understated. The potential uplift for a man with Robert’s service history (22 years, including 12 contracted-out years from 1985–1997) could be meaningful — potentially several hundred pounds per year or more, depending on the equalisation method used.
2. His CETV may not reflect the equalised amount. If the scheme has used a CETV calculation that doesn’t fully reflect the equalisation uplift, the £218,000 figure could be understating the true value of his benefits.

Transfer Value Analysis (TVA)

With the GMP context understood, we applied the standard Transfer Value Analysis (TVA) framework — required for all defined benefit transfer advice where the CETV exceeds £30,000.

Required Rate of Return (RRR)

The first step is to calculate the Required Rate of Return — the investment return the transferred funds would need to achieve, invested in the pension market, to replicate the DB benefits. We use a set of standardised assumptions:

• Assumed CPI inflation: 2.5% (the scheme’s revaluation and indexation rate)
• Target retirement age: 65 (Robert’s normal retirement date)
• Life expectancy: 87 for Robert, 90 for Sandra (actuarial averages; Robert is in good health)
• Spouse’s benefit included: 50% spouse’s pension for Sandra on Robert’s death

The RRR came out at 6.8% per annum.

Transfer Value Comparator (TVC)

We also calculated the Transfer Value Comparator (TVC) — the notional cost of buying equivalent benefits via an annuity in the open market. For a 61-year-old male with Robert’s profile, a level-indexed annuity paying £10,400/yr (escalating at CPI, with 50% spouse’s pension) would cost approximately £290,000–£320,000 in the open annuity market.

The CETV of £218,000 therefore represents roughly 68–75p in the pound of the replacement cost. Schematically, Robert would need to find an additional £72,000–£102,000 from investment growth just to replicate the guaranteed income — before accounting for his own life expectancy uncertainty.

GMP Equalisation Adjustment (Estimated)

We asked the scheme trustees for confirmation of GMP equalisation status. The scheme administrator confirmed:

• The scheme had applied the Conversion Method C2 (the most common approach, converting GMP rights into equivalent non-GMP rights of equivalent actuarial value)
• The equalisation had been applied to all deferred members in 2023
• Robert’s updated pension post-equalisation was £10,940/yr — an increase of £540/yr (5.2%)
• The CETV of £218,000 already reflected the equalised pension figure (it had been recalculated after the equalisation exercise)

This was good news for clarity — Robert’s CETV was accurate and he was not receiving a historically understated offer. However, it underscored that even with the uplift included, the RRR remained at 6.8% and the TVC gap remained significant.

The Flexibility Argument — and Why It Didn’t Override the Numbers

Robert’s main motivation for considering a transfer was flexibility. He had two specific concerns:

Concern 1: The Death-Benefit Question

Robert worried that if he died before 65, his 22 years of pension contributions would be “lost” — with only a relatively modest lump sum and spouse’s pension passing to Sandra. In a SIPP, the full pot would be available to Sandra (and ultimately their two adult children) without the restriction of a scheme-defined spouse’s benefit.

We explained the reality for Robert’s scheme:

• If Robert dies before reaching 65, the scheme would pay Sandra a 50% spouse’s pension of £5,470/yr (CPI-linked, for life)
• A death-in-deferment lump sum would also typically apply — often 3–5× the deferred pension — so potentially £32,820–£54,700 tax-free for the estate
• Under the 2027 IHT pension changes, uncrystallised SIPP funds will fall within Robert’s estate from April 2027 — eroding one of the traditional transfer arguments around IHT-free pension wealth passing to heirs

Concern 2: Early Access and Income Drawdown

Robert is currently working part-time and would ideally like to draw some income from pensions before age 65. He was aware that the Normal Minimum Pension Age (NMPA) would rise to 57 in 2028 — and that as he turns 62 in 2026, he is just within reach of accessing pension savings from age 57 under transitional rules.

However, we noted that:

• Robert’s DB scheme does have provision for a reduced early retirement pension from age 62 — at an actuarial reduction of approximately 4% per year before 65. Taking the pension at 62 would give him approximately £9,150/yr rather than £10,940/yr at 65 — a reduction of 16%.
• His SIPP (£67,000) and ISA (£28,000) are already available for flexible drawdown without needing to touch the DB pension. Together they can provide a meaningful income bridge from 61 to 65 or beyond.
• The case for transferring the DB specifically to gain flexibility was weakened once we mapped out that Robert already had flexible assets to draw on.

Income Sequencing Plan: Retain the DB, Flex the DC Assets

Rather than recommending a transfer, we worked with Robert on an income sequencing plan that uses his existing flexible assets first, then layers on the guaranteed incomes:

Phase 1 (Ages 61–64): Bridge from Flexible Assets

• Draw approximately £12,000/yr from a combination of ISA withdrawals and SIPP drawdown (within personal allowance)
• Allows Robert to work part-time without needing to draw the DB pension early
• ISA withdrawals are tax-free and don’t affect personal allowance
• SIPP withdrawals structured to remain within the £12,570 personal allowance — tax-free

Phase 2 (Age 65): DB Pension Begins

• DB pension: £10,940/yr (CPI-indexed)
• SIPP drawdown continues: flexible amounts on top
• Total pre-State Pension income: approximately £16,000–£19,000/yr depending on drawdown level
• Sandra’s TPS pension (est. £8,500/yr) also now in payment (her NRD ~age 60 under her scheme rules)

Phase 3 (Age 67+): State Pensions Layer On

• Robert’s State Pension: £9,800/yr
• Sandra’s State Pension: expected full £11,502/yr
• Household total pension income from 67: DB (£10,940) + SP Robert (£9,800) + TPS Sandra (~£8,500) + SP Sandra (£11,502) = approximately £40,742/yr before SIPP drawdown
• SIPP (remaining fund c.£40,000–£50,000 by this point, depending on drawdown pace) continues as a flexible reserve

State Pension Consideration — The Contracted-Out Deduction

One important point worth highlighting for people in Robert’s position: because his scheme was contracted out of SERPS between 1985 and 1997, his National Insurance record for those 12 years has a contracted-out deduction applied to his new State Pension calculation.

Under the transitional rules for the new State Pension (introduced April 2016), a “starting amount” was calculated based on the higher of the old and new rules. The contracted-out deduction reduces Robert’s starting amount — which is why his State Pension forecast is £9,800/yr rather than the full £11,502/yr.

Importantly, this deduction cannot be remedied simply by buying additional qualifying years. The deduction is fixed. Additional Class 3 NI years after 2016 can only top up any remaining shortfall from years where Robert had insufficient NI contributions — but they cannot overwrite the contracted-out adjustment.

We confirmed Robert’s NI record showed 38 qualifying years — meaning he was already at the maximum contribution threshold. No additional voluntary NI years were needed or available to increase his State Pension further.

GMP Equalisation: What Deferred Members Should Check

Robert’s case prompted us to outline the key questions any deferred DB pension member with pre-1997 contracted-out service should ask their scheme trustees:

1. Has GMP equalisation been completed for my benefits? Many schemes are still working through the process. If not yet done, your pension entitlement may be understated.
2. Which equalisation method has the scheme adopted? The most common is Method C2 (conversion); others include Method B (dual records), Method D1 (top-up payments at retirement). Different methods affect when and how the uplift applies.
3. Does my CETV reflect the equalised pension? If the scheme has completed equalisation but hasn’t yet updated CETVs, you may be receiving a transfer value based on a lower pension than you’re actually entitled to. Always request the CETV after equalisation is confirmed.
4. Am I affected by GMP fixed-rate revaluation? Deferred GMPs (pre-1997 benefits) revalue at either a fixed rate (currently 3.25% pa) or by reference to National Average Earnings, depending on when you left service. This affects the eventual value of your GMP at retirement.
5. What is my scheme’s GMP payment age? For men in pre-1995 schemes, GMP was typically payable from 65. For women, it was 60. Post-equalisation, different transitional arrangements may apply to how your GMP is paid.

Outcome and Recommendation

Our formal recommendation to Robert was clear: do not transfer the defined benefit pension.

The headline reasons:

• RRR of 6.8% pa is well above the typical achievable long-term return threshold
• The CETV represents only 68–75p/£ of the open market replacement cost
• GMP equalisation has been completed and the CETV already reflects the uplift — there is no “hidden value” to unlock via transfer
• Robert and Sandra together have two DB pensions, State Pensions, and existing DC/ISA assets — the household already has strong guaranteed income; no additional DB guarantee is needed via a SIPP strategy
• The 2027 IHT changes significantly erode the death-benefit and IHT-planning argument for transferring to a SIPP
• Early access can be achieved via SIPP and ISA assets without touching the DB pension

We did recommend the following actions within Robert’s existing arrangements:

• Consolidate SIPP: Robert had two older personal pensions (£19,000 and £11,000 with legacy providers charging 1.4% and 1.2% pa respectively). These were consolidated into his main SIPP to reduce charges and simplify management.
• Review SIPP investment strategy: At 61 with a 4-year runway before the DB pension begins, a moderately cautious approach with some growth exposure was appropriate — the DB provides a floor.
• Expression of Wishes updated: Robert had not reviewed his Expression of Wishes on the DB scheme for over a decade. This was updated to name Sandra and include their two adult children.
• Review scheme early retirement factors: Robert was advised to request the scheme’s actuarial reduction factors for taking the pension at 62 vs 65, so he had the numbers if his circumstances changed.

7 Lessons from Robert’s Case

1. GMP equalisation is ongoing — always verify your status. If you left a contracted-out scheme before 1997, ask your trustees whether equalisation has been completed and reflected in your CETV. Don’t assume.
2. A higher CETV doesn’t always mean a better transfer case. Robert’s CETV had been uplifted by equalisation — but the RRR still made transfer unattractive. The absolute size of the CETV matters less than the relationship between the CETV and the guaranteed benefits.
3. Pre-1997 contracted-out service affects your State Pension — permanently. The deduction for contracted-out years cannot be remedied by buying NI years. It’s worth understanding this when planning your total retirement income.
4. Two DB pensions in a household changes the risk calculus. When both spouses have guaranteed income from DB schemes and State Pension, the arguments for transferring a single DB pension to gain flexibility are significantly weaker.
5. Flexible assets reduce the case for transferring DB pensions. If you already have SIPPs and ISAs that can provide early access income, you don’t need to transfer your DB to achieve flexibility. Use flexible assets first; preserve guaranteed assets.
6. The 2027 IHT changes have reshaped the death-benefit argument. Pension pots will be subject to IHT from April 2027. If your reason for considering a transfer was to leave a pension pot to your children, that argument has been significantly weakened. Seek specialist estate planning advice.
7. Expression of Wishes are easily forgotten — but critically important. Keeping these up to date on all pension schemes ensures that, on death, pension trustees have clear guidance on your wishes for distributing death benefits. Review them every 2–3 years or after any major life change.

Seeking Professional Advice

GMP equalisation adds a layer of technical complexity to any defined benefit pension transfer analysis. Getting the numbers right — and understanding whether your CETV reflects your true entitlement — requires specialist knowledge of both pension legislation and the actuarial methods schemes use.

If you left a workplace pension before 1997 and are considering a transfer, it’s particularly important to work with a qualified pension transfer specialist who understands the GMP framework. The wrong decision — transferring a pension that is undervalued or that provides guaranteed benefits far in excess of what a SIPP could replicate — can be very costly and is largely irreversible.

Under FCA rules, defined benefit pension transfer advice for pots over £30,000 must be provided by a FCA-authorised adviser holding the appropriate pension transfer qualifications. This rule exists to protect people from making irreversible decisions without proper guidance.
