Hotel EV Charging RoI Calculator

How to Use This Calculator

EVs now account for over 27% of UK new car sales (SMMT, 2026), and EV drivers actively filter for charging when booking accommodation. SMS plc found that 48% of UK EV drivers will simply not stay at a hotel without on-site charging. Zapmap reports hotel charging usage grew 36% in 2025 — yet the majority of UK hotels still don’t offer it, making early investment a clear competitive advantage.

EV charging helps hotels in two ways: attracting new guests who won't stay without charging, and retaining existing guests who might otherwise switch to a competitor that has it.

Set your target payback period and the calculator will tell you how many EV guest room nights per month you need — whether from new bookings or retention of loyal EV-driving customers — to justify your investment.
