Park details
Number of holiday lets
20
The total number of bookable holiday lets on your park. This sets the ceiling for how many guests could be on site at peak occupancy.
Peak occupancy (summer)
90%
Your busiest summer occupancy rate. The model applies this in full for 17 summer weeks, 75% for 16 shoulder weeks (spring + autumn), and 33% for 19 off-season weeks — giving a realistic annual charging volume.
Summer — peakShoulder — 75%Off-season — 33%
Guests arriving by EV
25%
The share of your guests who arrive in an electric vehicle. UK EV uptake is growing fast — around 20–25% of new car sales are now electric. Holiday park guests tend to be active drivers, so EV ownership may track or exceed the national average.
Tariff & electricity
All figures are exclusive of VAT
Guest charge (p/kWh)
50p
The rate you charge guests per kWh, exc. VAT. Public rapid chargers typically cost 65–85p/kWh. A destination rate of 45–55p is competitive, convenient for guests, and generates a healthy margin over your electricity cost and Voqa commission.
Drivers pay 60p/kWh inc. VAT
Your electricity rate
27p
Your business electricity unit rate in pence per kWh, exc. VAT. Check your latest bill — business rates typically range from 20–40p/kWh. The gap between this, the Voqa commission, and your guest tariff is your net margin per kWh.

Annual sessions
Total charging plug-ins across the year. Each EV guest charges every other night — 2 sessions across a 7-night stay — consuming a full 75 kWh battery equivalent (69 kWh net of charging losses). Each session delivers ~34.5 kWh at an average of 5.25 kW over ~6.5 hours.

Bays to electrify
The number of parking bays that need a charger installed, sized for peak summer demand. Each Voqa One unit is dual-port — serving two vehicles simultaneously from a single 7 kW connection. Because guests charge every other night, only half your on-site EVs need a bay at any one time.

Hardware payback
How many months before net revenue covers your hardware and installation costs, exc. VAT. Based on £2,800 per Voqa One unit plus £1,000 installation per bay. Net revenue deducts electricity cost and the 6p/kWh Voqa commission. Does not include civils or groundworks, which vary by site.
