What CPI +1 means in specialist supported living leases

Many specialist supported living (SSH) leases link rent reviews to an inflation index — often the Consumer Prices Index (CPI), sometimes with an additional percentage point such as “CPI + 1”. The phrase sounds precise. In practice, the outcome depends entirely on the executed lease wording.

CPI measures a basket of consumer prices published by the Office for National Statistics. A CPI-linked review typically adjusts rent by reference to a defined index series, a base date, a review date and a formula. “CPI + 1” usually means the percentage change in CPI plus one percentage point — but only if the lease says so, and only within any stated caps, floors or collars.

Caps and floors matter. A lease may limit how far rent can rise or fall in a review period. Without reading those limits, an investor can overestimate income resilience or underestimate downside. The review may also specify which CPI series applies, how rounding works, and what happens if the index is discontinued.

Illustrative calculators — including Bhenito’s SSH CPI tool — show arithmetic under assumed inputs. They are educational. They do not forecast inflation, guarantee future rent, or replace the lease. Actual rent follows the contract, counterparty performance and any lawful variations.

For diaspora and first-time SSH investors, the diligence question is not “what does CPI +1 sound like?” It is: what does this lease actually say about review mechanics, timing, caps, floors and dispute resolution — and have independent solicitors confirmed it?
