What is the triple lock pension and how is it calculated?

The triple lock pension increases the state pension each April by the highest of September CPI inflation, average earnings growth, or 2.5%. The government compares those three measures, picks the highest, and applies it to the full rate. This protects retirees when prices surge or when wages rise strongly after a spike.

What could cause a ‘double boost’ to the state pension?

A double boost can happen when September CPI jumps one year, lifting the state pension, and average earnings growth becomes the highest factor the next year as pay catches up. Energy-driven inflation often starts this sequence by raising CPI first, then flowing through to wage negotiations and settlements later.

How might this affect gilts and interest rates?

Higher CPI and a larger pension uprating can increase borrowing needs and gilt issuance. That may steepen the curve and raise auction concessions. If inflation proves sticky, the Bank of England could delay cuts, supporting sterling but pressuring duration. Inflation-linked gilts may benefit if breakevens widen on stronger headline readings.

What can retirees do to prepare for an inflation spike?

Review energy tariffs, switch where savings are clear, and build a small cash buffer. Prioritise paying down variable-rate debt, and consider spreading large purchases to manage price risk. For investments, diversify income sources and avoid overconcentration in long-duration assets. Track CPI prints and Ofgem cap updates to make timely adjustments.

UK State Pension March 14: Triple Lock ‘Double Boost’ Revives CPI Risk

ByDanny Kontos March 15, 2026March 15, 2026

The state pension faces fresh attention as reports warn an Iran-driven energy shock could push UK inflation above 3%. That would activate the triple lock pension and may set up a second rise if wages catch up. This possible double boost supports retiree incomes but adds fiscal and gilt-supply risks. With the UK inflation outlook uncertain and the OBR inflation forecast under review this spring, investors should watch energy, CPI prints, and rates guidance closely. We outline what this means for portfolios in Britain today.
