Osprey vs InstaVolt charging costs in the UK
If you use rapid public chargers in the UK, Osprey and InstaVolt are two of the names you are most likely to see on longer trips. Both offer rapid or ultra-rapid charging, both support simple card payments, and both are widely used by drivers who need a quick top-up away from home.
The cost difference depends heavily on how and when you pay. Based on published prices available on 9 May 2026, Osprey is simpler: 87p per kWh by contactless, or 82p per kWh using the Osprey app or RFID card. InstaVolt is more variable: its standard pricing is 92p per kWh at peak times using the app or RFID, 55p per kWh off-peak using the app or RFID, and 92p per kWh at all times if you pay contactless.
That means Osprey is usually cheaper for daytime charging, while InstaVolt can be much cheaper if you can charge off-peak through the app. Prices can change quickly, so always check the charger screen, network app or official pricing page before starting a session.

Quick answer
For most UK drivers comparing Osprey vs InstaVolt charging costs, the cheapest option depends on the time of day and payment method.
| Scenario | Osprey | InstaVolt | Cheaper option |
|---|---|---|---|
| Contactless daytime charge | 87p per kWh | 92p per kWh | Osprey |
| App daytime charge | 82p per kWh | 92p per kWh | Osprey |
| App off-peak charge | 82p per kWh | 55p per kWh | InstaVolt |
| Contactless off-peak charge | 87p per kWh | 92p per kWh | Osprey |
The big takeaway is simple: InstaVolt’s off-peak app rate is the standout bargain, but Osprey is cheaper for most normal daytime charging.
Current Osprey charging prices
Osprey’s official pricing is straightforward:
- 87p per kWh when paying by contactless bank card
- 82p per kWh when using the Osprey app or Osprey RFID card
- No connection fee, according to Osprey’s pricing page
- Third-party roaming prices can vary, so check your provider before plugging in
Osprey also says its network accepts contactless bank cards, Apple Pay, Google Pay and several roaming options.
There is also a weekend app promotion. Osprey says its Weekend Saver Rate gives app users 10% off charging sessions from 00:00 Saturday to 23:59 Sunday. If that discount applies to the standard 82p per kWh app rate, the effective weekend app price would be about 73.8p per kWh. Check the live app pricing and promotion terms before relying on that figure.
Current InstaVolt charging prices
InstaVolt’s standard pricing is more time-sensitive.
Its official pricing terms list:
- 92p per kWh peak for InstaVolt app and RFID users, from 07:00 to 20:00
- 55p per kWh off-peak for InstaVolt app and RFID users, from 20:00 to 07:00
- 92p per kWh at all times for contactless and fleet roaming users
InstaVolt says the off-peak rate applies when the session is started during the off-peak window. The key catch is payment method: contactless users do not get the 55p per kWh off-peak rate under the standard tariff.
There is also special pricing at InstaVolt’s Winchester Superhub during a summer promotion period, but that is site-specific rather than network-wide.
What a typical top-up costs
Public charging is priced per kWh, so the easiest comparison is to look at common top-up sizes. A 20 kWh top-up might add roughly 60 to 80 miles in many EVs, depending on efficiency. A 40 kWh top-up is a substantial motorway recharge. A 60 kWh charge is close to the usable capacity of some family EV batteries, though most drivers will not regularly charge from empty to full on a rapid charger.
| Network and payment method | 20 kWh | 40 kWh | 60 kWh |
|---|---|---|---|
| Osprey contactless at 87p per kWh | £17.40 | £34.80 | £52.20 |
| Osprey app or RFID at 82p per kWh | £16.40 | £32.80 | £49.20 |
| InstaVolt peak app or RFID at 92p per kWh | £18.40 | £36.80 | £55.20 |
| InstaVolt contactless at 92p per kWh | £18.40 | £36.80 | £55.20 |
| InstaVolt off-peak app or RFID at 55p per kWh | £11.00 | £22.00 | £33.00 |
The difference can be meaningful. A 40 kWh daytime app charge costs £32.80 on Osprey and £36.80 on InstaVolt, a £4 gap. But if you can start the same 40 kWh InstaVolt app session off-peak, the cost drops to £22.00, which is £10.80 cheaper than Osprey’s normal app rate.
App, contactless and RFID differences
This is where many drivers get caught out. The charger brand is not the only thing that matters. The payment method can change the price too.
With Osprey, the app or RFID card is cheaper than contactless by 5p per kWh. That saves:
- £1 on a 20 kWh top-up
- £2 on a 40 kWh top-up
- £3 on a 60 kWh top-up
With InstaVolt, the app matters even more because it unlocks the off-peak rate. Contactless is simple, but the standard contactless rate is 92p per kWh at all times. If you regularly charge after 20:00 or before 07:00, using the InstaVolt app or RFID can make a large difference.
For an occasional emergency top-up, contactless is still useful because it avoids account setup. For regular use, the app is usually worth having on your phone for both networks.
Is InstaVolt cheaper off-peak?
Yes, if you use the InstaVolt app or RFID and start the session in the off-peak window.
InstaVolt’s listed 55p per kWh off-peak app rate is much lower than Osprey’s normal 82p per kWh app rate. On a 60 kWh charge, that is £33.00 with InstaVolt off-peak versus £49.20 with Osprey app pricing.
That said, off-peak public charging is only useful if it fits your routine. It works best for:
- shift workers
- early morning commuters
- drivers near an accessible InstaVolt site
- road trips where an evening or overnight stop is convenient
- drivers without home charging who can plan around cheaper public sessions
It is less useful if you mainly charge during lunchtime, school runs, shopping stops or motorway journeys in the middle of the day.
Does Osprey have off-peak pricing?
Osprey does not list a standard weekday off-peak tariff in the same way InstaVolt does. Its normal public pricing is a simple flat rate, with 87p per kWh for contactless and 82p per kWh in the app or by RFID.
However, Osprey does list a Weekend Saver Rate for app users, giving 10% off weekend sessions from Saturday morning to Sunday night. Based on the standard 82p app rate, that would be equivalent to about 73.8p per kWh, although drivers should check the app and live terms before starting a charge.
For drivers who value predictability, Osprey’s pricing is easier to understand. For drivers who can time their charging around off-peak hours, InstaVolt has the stronger potential saving.
Network size, speed and convenience
Cost is only part of the story. A cheaper charger is not much use if it is in the wrong place, blocked, broken or too slow for your stop.
Osprey says its network includes 1,500+ rapid charging stations, with charger speeds of 300kW+ available on parts of the network. InstaVolt is also one of the UK’s biggest rapid charging brands. Zapmap listed InstaVolt at 2,332 EV chargers across the UK at the end of March 2026 and classed it as an EV Driver Recommended Network 2026 in the large rapid and ultra-rapid category.
In practical terms:
- Choose Osprey if it is on your route, you want simple pricing, or you are charging by contactless in the day
- Choose InstaVolt if it is convenient and you can use the app off-peak
- Choose the working, available charger first if you are low on battery
Which network is better value?
Osprey is better value for most daytime charging. It is cheaper than InstaVolt on both contactless and app pricing during standard peak hours.
InstaVolt is better value if you can use its off-peak app or RFID rate. At 55p per kWh, it undercuts Osprey’s standard app pricing by 27p per kWh. That is a large saving on bigger top-ups.
The best choice depends on your charging pattern:
| Driver type | Best fit |
|---|---|
| Daytime contactless user | Osprey |
| Regular app user charging in the day | Osprey |
| Off-peak app user | InstaVolt |
| Weekend Osprey app user | Osprey may be attractive with its weekend saver |
| Driver choosing purely by network footprint | Check live maps, both are major rapid networks |
| Driver on a low battery | Use the nearest reliable available charger |
Simple rule before you plug in
Before starting a public rapid charge, check four things:
- Price per kWh on the app or charger screen
- Payment method, because app, contactless and roaming can differ
- Session timing, especially for InstaVolt off-peak rates
- Parking restrictions, because some host sites have maximum stay rules or car park terms
Also remember that roaming cards and third-party apps can have their own pricing. Do not assume the direct network price always applies.
FAQs
Is Osprey cheaper than InstaVolt?
Usually, yes, for daytime charging. Osprey lists 87p per kWh by contactless and 82p per kWh through its app or RFID card. InstaVolt lists 92p per kWh for peak app, RFID and contactless charging. InstaVolt becomes cheaper if you use its 55p per kWh off-peak app or RFID rate.
What is the cheapest way to use InstaVolt?
The cheapest standard way is to use the InstaVolt app or RFID card during the off-peak window, listed as 20:00 to 07:00. InstaVolt’s terms say the session must be started during those hours. Contactless does not get the off-peak rate under the standard pricing table.
What is the cheapest way to use Osprey?
The cheapest normal Osprey rate is the app or RFID price at 82p per kWh. Osprey also advertises a Weekend Saver Rate with 10% off app charging sessions from 00:00 Saturday to 23:59 Sunday. Check the app and live promotion terms before starting a session.
Do Osprey and InstaVolt charge connection fees?
Osprey states that there are no connection fees on its pricing page. InstaVolt’s pricing terms focus on pence-per-kWh rates, but drivers should still check live terms, charger screens and payment providers because public charging costs can include site-specific, roaming, overstay or promotional conditions.
Why can price comparison sites show different numbers?
Comparison services are useful, but pricing can change and network terms can be updated between refreshes. For a live charging decision, treat the operator’s own app, charger screen and official pricing terms as the most important sources.
Verdict
Osprey is the easier network to understand and the better-value choice for most ordinary daytime rapid charging. Its app price is lower than contactless, the saving is clear, and the flat-rate structure avoids much of the timing confusion.
InstaVolt is more expensive at peak times, but its off-peak app rate changes the picture completely. If you can charge between 20:00 and 07:00 and the site is convenient, InstaVolt can be significantly cheaper than Osprey.
For most drivers, the sensible answer is to keep both apps installed. Use Osprey when you want simple daytime pricing, use InstaVolt when off-peak charging fits your routine, and always check the live price before you plug in.
