Every Jersey Electricity tariff available right now — unit rate, standing charge, contract length, exit fee and renewable status. Last verified 1 April 2026.
Jersey is a Crown Dependency and is therefore not subject to the GB Energy Price Cap. Instead, JEC publishes a single tariff schedule each year, effective 1 April, which is reviewed by the Jersey Competition Regulatory Authority (JCRA) before taking effect. All unit rates below exclude Jersey GST (5%). There are no exit fees on JEC domestic tariffs, you can switch between tariffs free of charge once a year per meter (additional changes incur a £33 administration fee). JEC supplies electricity only; for gas see Jersey Gas.

Selectra expert
Which Jersey Electricity tariff fits you, and what will you actually pay?
JEC’s tariff schedule is set once a year for the whole island, so the choice is not which supplier, it is which JEC tariff. Domestic (anytime) is the safest default for most homes; Economy 7 pays off if you have storage heaters or an EV; EVNight beats every other tariff if you can shift charging to the 00:00-07:00 window.
Domestic (anytime)
Variable
Best fit if — low-to-medium consumption households (annual use under 5,000 kWh) without storage heaters or an EV
Skip if — you heat the home electrically with night-rate storage heaters, Economy 7 or Economy 12 will be cheaper
What you'll actually pay
About £993/year at the JEC TDCV of 3,600 kWh (Domestic anytime, 18.66 p/kWh + 27.79p/day standing, excl. GST).
The right starting point for most island households, simple to read on the bill and immune to evening-rate spikes.
Economy 7
Time-of-use
Best fit if — storage-heater homes, immersion-cylinder hot water, or households charging an EV overnight on a regular socket
Skip if — less than 35% of your annual kWh falls inside the 00:30-07:30 night window, you’ll pay a premium during the day
What you'll actually pay
Mixed-rate annual estimate of about £1,070 for a 3,600 kWh storage-heater household using ~50% of energy at night.
The canonical Jersey winter tariff, only worth signing up if you actually shift load to the cheap window.
Economy 12 (Heat & Power)
Time-of-use
Best fit if — large storage-heater properties that also need an afternoon top-up boost
Skip if — your storage heaters hold heat all day, the daytime peak rate eats the gain
What you'll actually pay
Comparable to Economy 7 but with a third rate band. Detailed picture on the JEC bill.
A niche product. Useful only if your storage heaters genuinely run short by mid-afternoon.
Economy 20
Time-of-use
Best fit if — second homes and seasonal properties used outside the evening peak window
Skip if — you cook, dry clothes or charge an EV between 17:00 and 21:00, the peak rate is brutal
What you'll actually pay
Off-peak unit rate of 13.56 p/kWh is one of the cheapest published in the British Isles; peak rate of 48.25 p/kWh is one of the highest.
High-risk, high-reward. Only sign on if you can run an inflexible 4-hour evening blackout discipline.
EVNight
Smart EV
Best fit if — EV drivers who can reliably charge between 00:00 and 07:00 (about 6,000+ miles a year)
Skip if — your work pattern forces daytime charging at the standard rate
What you'll actually pay
Charging a 60 kWh EV from 20% to 80% on the night window costs about £2.10, against £7.66 on Domestic anytime.
The cheapest published EV night rate on any UK Crown Dependency. A clear winner for overnight-charge households.
Comfort Heat Pump
Smart heat pump
Best fit if — homes with an MCS-certified air-source or ground-source heat pump on the JEC Comfort Heat plan
Skip if — you don’t yet have a heat pump, the tariff is gated to certified installations
What you'll actually pay
Discounted unit rate during the long off-peak window. Final savings depend on your COP and house fabric.
Niche but a clear winner for the right setup, pair it with the JEC heat-pump grant for maximum return.
Solar PV Export (Microgen)
SEG export
Best fit if — households with rooftop solar PV (or small wind) exporting surplus to the grid
Skip if — you self-consume most of your generation, the export rate is well below the import rate
What you'll actually pay
8.30 p/kWh per kWh exported. Reviewed annually; no fixed-term contract.
Worth claiming if you have spare roof, but the economics favour self-consumption over export.
All figures are based on the JEC Tariff Schedule effective 1 April 2026, excluding Jersey GST (5%). The JEC Typical Domestic Consumption Value (TDCV) is 3,600 kWh per year, higher than the UK Ofgem electricity TDCV of 2,700 kWh because Jersey homes rely on electricity for heating where the mainland uses gas.
How to compare UK tariffs
Three numbers that decide your bill
1
Unit rate (p/kWh) — the cost of the energy you actually use. The Energy Price Cap caps the unit rate on the default (Standard Variable) tariff. Fixed tariffs are usually slightly above or below the cap.
2
Standing charge (p/day) — what you pay per day even if you use zero energy. Covers network costs, smart-meter rollout and policy levies. About 53p/day for electricity and 32p/day for gas on a typical 2026 tariff.
3
Exit fee — what you pay to leave early on a fixed tariff. Typically £25-£75 per fuel. None on Standard Variable. None in the final 49 days of any fixed contract.

Is JEC the cheapest for your usage?
Headline rates lie. The only way to know is to compare against your real annual kWh. Selectra's comparison uses your postcode + 12-month usage to find the cheapest current deal.
Every UK domestic energy tariff has two components: a standing charge (a flat fee in pence per day, even if you use zero energy), and a unit rate (in pence per kWh you actually consume). Your bill = (standing charge × days) + (unit rate × kWh used) + VAT (5%). Compare both numbers — a tariff with a low unit rate but a high standing charge can cost more than the reverse if you use little energy.
The Energy Price Cap set by Ofgem limits how much suppliers can charge for the default (Standard Variable) tariff. It is reviewed every three months. It does not cap fixed-term tariffs — those can be cheaper or more expensive than the cap depending on wholesale prices.
Most UK fixed-term tariffs include an exit fee (typical range: £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. The default Standard Variable tariff has no exit fee.
Many UK suppliers offer 'green' or '100% renewable' tariffs which match your annual consumption with REGO certificates. This is a paper-trail match, not a guarantee that the electrons reaching your home are renewable — but it does fund continued renewable generation. Tariffs marked '100% renewable' below carry REGO backing.
If wholesale prices are forecast to rise, fixing locks in today's price for the contract length. If they are forecast to fall, the Standard Variable tariff (capped by Ofgem) tracks the wholesale market down. The right choice depends on your appetite for stability vs. potential savings — Selectra's comparison tool factors in both.
