Is fixed or variable price better with Sima Energia in June 2026?
The PSV (Punto di Scambio Virtuale) is Italy's monthly reference price for natural gas: when it rises your bill increases, when it falls you save automatically. Variable offers follow the PSV, while fixed ones like Gas Fix Casa Switch do not. Use the graph below to help you choose between fixed and variable prices.
With the indexed offer Gas Index Casa Web from Sima Energia and a spread of 0.149 €/Smc, as of June 2026 you are currently paying about 0.653 €/Smc. The fixed tariff Gas Fix Casa Switch at 0.630 €/Smc would currently be cheaper, with an estimated saving of €36/year compared to the indexed.

Fixed or variable gas tariff: here are the differences
In the free natural gas market, suppliers can offer either fixed-price or indexed tariffs. With a fixed price, the cost of gas (€/Smc) stays the same for the entire duration of the contract, whereas with indexed offers the price of gas changes each month based on the PSV (Punto di Scambio Virtuale, Italy's wholesale gas reference index).
Sima Energia offers both types: you can choose the stability of a fixed price with offers like Gas Fix Casa Switch, or the flexibility of a PSV-indexed contract with offers like Gas Index Casa Web. Both options have their pros and cons.
- When the natural gas market price falls, your bill decreases automatically in line with the change
- There is no fixed contract term and you can switch offer or supplier at any time without early exit penalties
- During periods of high gas price volatility, your bill can rise significantly and monthly costs become harder to predict
- The gas price (€/Smc) stays fixed for the entire contract, regardless of how the PSV moves
- Ideal for those who heat their home with gas and want a predictable bill with no unexpected increases in winter
- If the PSV falls after activation, you continue paying the agreed price without benefiting from market drops
