Guernsey’s property market has delivered another bullish quarter for landlords and homeowners alike, with sale prices edging higher and the rental sector posting eye-watering five-year growth that will sharpen the appetite of buy-to-let investors eyeing the Channel Islands.
According to the latest Residential Property Prices Bulletin published by the States of Guernsey, the average local market property changed hands for £604,094 between January and March 2026, a 4.1% increase on the same quarter a year earlier, when the average stood at £580,412. The figure also represents a 1.4% uplift on the final quarter of 2025, when properties typically sold for £595,820.
The rental market has been the standout performer, however. Tenants in the bailiwick are now paying an average of £2,170 a month, a 45% leap on the £1,498 recorded in the first quarter of 2021. While the quarter-on-quarter movement was a more modest 0.4%, rents have still risen 4.9% on the year, comfortably outpacing mainland UK inflation and reinforcing Guernsey’s reputation as a high-yield outpost for income-focused landlords.
The volume picture, by contrast, tells a more measured story. Just 163 local market transactions completed in the opening three months of 2026, down sharply on the 246 recorded in the closing quarter of 2025, and marginally below the 166 sales logged in the same period last year. The figure also sits below the 167 transactions seen five years ago, suggesting that stock constraints, rather than weakening demand, are once again the principal brake on activity.
Activity at the top end of the market has been more spirited. The open market segment, which is accessible to buyers without local residency status, saw a pick-up in transactions during the quarter. However, the average open market sale price slipped to £1,494,188, lower than the £1,560,000 recorded in the previous quarter and well shy of the £1,913,438 averaged in the same period of 2025, a sign that more modestly priced trophy homes are dominating the order book, rather than blue-chip estates.
For investors, the data points to a familiar Channel Islands story: a structurally undersupplied market, robust rental growth, and a resilient capital values trajectory. With yields tightening on much of the mainland and the south-east of England in particular showing signs of fatigue, Guernsey’s combination of compounding rents and capital appreciation will continue to make it an attractive, if exclusive, proposition for portfolio landlords seeking diversification beyond the M25 commuter belt.
Whether the rental trajectory can continue at its current pace remains the open question. A 45% five-year rise inevitably raises affordability concerns for local tenants, and any policy intervention from the States, whether on stamp duty equivalents, open market quotas, or tenancy reform, could shift the calculus quickly. For now, though, the numbers point firmly in one direction.
