How It Works
Pension consolidation compares the total annual charges across multiple separate pension pots against the charges of a single combined pot. Each pot typically has a platform fee (0.2-0.5%) plus fund charges (0.1-1.5%), applied as a percentage of the pot value. Over 20-30 years, even a 0.5% fee difference compounds dramatically: on a £100,000 pot over 25 years at 5% growth, a 1.5% charge leaves £181,000 while a 0.5% charge leaves £261,000.
The calculation totals current annual charges across all pots using each scheme's fee schedule, then compares against the projected charges of the target consolidated scheme. Exit penalties must be factored in, particularly for older contract-based pensions that may levy early transfer charges of 1-5%. Some workplace pensions include valuable employer contribution matching or lower charges that would be lost on transfer.
Protected benefits such as guaranteed annuity rates (GARs), protected tax-free cash above 25%, or defined benefit entitlements require careful valuation before consolidation. The calculator flags pots with potential safeguarded benefits and estimates the monetary value of guaranteed features against the fee savings from consolidation.
Should I consolidate UK pensions? Average UK worker has 11 jobs over career → multiple workplace pensions accumulated. Consolidation benefits: single account, easier to track, potentially lower fees, simpler retirement planning. Drawbacks: lose valuable guarantees (Guaranteed Annuity Rates, Defined Benefit features, protected tax-free cash, life cover). NEVER move: DB (final salary) pensions without specialist advice — usually leave alone; pensions with Guaranteed Annuity Rates of 8%+ (compare with current 6-7% rates).
Which pensions to consolidate vs keep separate. CONSOLIDATE: Old workplace DC pensions with high fees (>1%); small pots under £10k (admin disproportionate); old SIPPs with limited investment choice; pensions where you've lost track of provider. KEEP SEPARATE: Defined Benefit (final salary) — value rarely matches transfer offer; pensions with Guaranteed Annuity Rates (often 8-12% vs current 6-7%); protected tax-free cash above 25%; deferred state pension and supplementary pensions.
UK pension consolidation process. Step 1: Find lost pensions via Pension Tracing Service (gov.uk — free). Step 2: Get fund value, charges, and investment information from each provider. Step 3: Choose receiving pension (best UK SIPPs 2026: Vanguard SIPP 0.15% platform; AJ Bell 0.25%; Interactive Investor £11.99/month flat; Hargreaves Lansdown 0.45%). Step 4: Complete transfer forms — providers handle process electronically. Step 5: Verify all transfers landed correctly (4-12 weeks typical). Cost: usually free; some old plans charge exit penalties.
Transfer warning — when to get advice. MANDATORY independent advice (FCA rules) for: any DB pension transfer over £30,000; pensions with safeguarded benefits. Adviser fee: typically £2,000-£5,000 for DB transfer analysis (cheap relative to mistake). 'Pension transfer scams' common — cold callers, unauthorised firms. NEVER transfer based on unsolicited contact. Check FCA register: fca.org.uk — only use authorised advisers. Pension Wise (free government service for over-50s): general guidance available without advice fees.
Best UK SIPP providers 2026. Low-cost passive: Vanguard SIPP (0.15% platform + 0.22% fund OCF = 0.37% total), limited fund range; Interactive Investor (£11.99/month flat + 0.20% funds = best for £40k+ pots). Full-feature: AJ Bell SIPP (0.25% platform + chosen fund OCF); Hargreaves Lansdown (0.45% platform + chosen fund OCF — more expensive). Stocks & shares choice: HL/AJ Bell offer 3,500+ funds vs Vanguard's 80. Total platform fees over 30 years on £100k pot: HL £140k; AJ Bell £85k; Vanguard £55k. Fees matter dramatically over long time horizons.
Consolidating three pension pots into one SIPP
- Pot A: £45,000 at 1.2% annual charge = £540/year in fees
- Pot B: £28,000 at 0.9% annual charge = £252/year in fees
- Pot C: £17,000 at 1.5% annual charge = £255/year in fees
- Total current fees: £1,047/year on combined £90,000 (effective 1.16%)
- Consolidated SIPP at 0.35% platform + 0.12% fund = 0.47%, costing £423/year — saving £624/year
