Pros & cons
What we hear from Guernsey Electricity customers
Strengths
- Sole electricity supplier and distributor for the bailiwick of Guernsey, with supply availability above 99.9% thanks to the Channel Islands Electricity Grid (CIEG) and the Vale Power Station emergency back-up.
- Imported electricity declared 100% low-carbon since January 2020, giving a carbon intensity comfortably below the GB grid average and backed by Guarantees of Origin.
- Wholly owned by the States of Guernsey: the Board is accountable to the States of Deliberation and tariff decisions are debated in public, with the GCRA reviewing material changes.
- Walk-in customer centre at Electricity House (North Side, Vale) plus a local phone team that operates on island time and understands Guernsey-specific issues — electric-heating retrofits, EV charging on Super Economy 12, the role of the Vale Power Station.
- Local diesel generation at the Vale Power Station is held as belt-and-braces back-up against any subsea cable interruption, alongside CIEG’s redundant import routes via Jersey.
Weaknesses
- Guernsey is a monopoly market: there is no competing supplier, so service-level shortcomings cannot be solved by switching.
- Tariffs sit clearly above the GB price cap, and the 1 July 2025 increase moved the primary standing charge from £68.25 to £86.75 per quarter — meaningful for low-consumption homes.
- Complaint-handling performance has been rated mixed by the GCRA in successive annual reviews; complex disputes can take longer than at GB suppliers.
- Smart-meter rollout has been gradual; many households remain on quarterly estimated bills and have limited real-time visibility on day-to-day consumption.
Selectra verdict
Our independent take on Guernsey Electricity
Guernsey Electricity is a textbook small-island state-owned utility: highly reliable on supply, transparent on ownership, but expensive and slow on the everyday customer-service side. Because there is no competing supplier, the value of reviews is to flag what to expect and how to engage well, not to choose between options.
Customers most often lose money by sitting on the wrong tariff (Domestic Standard vs Super Economy 12 vs Superheat vs Heat Pump) or by not registering for vulnerable-customer support when they would qualify. If a complaint cannot be resolved internally, the GCRA route is well established and worth using.

Walk-in office was a lifesaver
Bought a flat with electric heating and no idea which tariff to be on. Popped into the office at Vale, the gentleman printed off my previous occupant’s last year of consumption and ran it through three tariff scenarios. Saved me about £200 a year on the spot. Excellent.

Selectra expert comment
The walk-in customer centre at Electricity House (Vale) is the single most useful resource for any Guernsey Electricity customer. We routinely recommend a face-to-face tariff review for new occupants, particularly in homes with storage heaters or immersion tanks where Super Economy 12 or Storage Heating can make a material difference.
Reliable supply, opaque billing
Never had a power cut worth complaining about in 12 years on the island. Bills however have always been a bit of a mystery: standing charge, capacity charge, day rate, night rate. Asked once for an explanation and got a friendly answer, but it took two emails.
— Andrew, Castel
Trustpilot
Selectra expert comment
A familiar pattern: operational excellence paired with billing complexity. Guernsey Electricity’s tariff schedule has more components than most GB suppliers because it has to recover both supply costs and local-distribution capital. Customers can ask for an itemised tariff explanation in writing — it is a useful document to keep on file.
Estimated bills keep arriving
Submitted manual readings every quarter for three years. Bills still come out estimated and I have to phone to get them recalculated. Promised a smart meter "soon" three years running. Otherwise the people I deal with are polite and competent.
— Sarah, St Sampson
Trustpilot
Selectra expert comment
Estimated-bill recurrence is a structural issue while the smart-meter rollout catches up. Until your meter is upgraded, submit a reading on the first day of every quarter through MyAccount, and request a full rebill from the last accurate read if estimated charges ever exceed your real consumption. You are within your rights to demand recalculation.
Tariffs higher than mainland by a long way
Moved over from Hampshire. The kilowatt-hour price is dramatically higher than what I was paying in England. I get that it is an island grid, but the gap is larger than I expected and the bills have stung this first winter.
— James, Vale
Trustpilot
Selectra expert comment
New-arrival sticker shock is a constant theme on Guernsey. The unit rate sits above the GB price cap because Guernsey Electricity recovers cable, generation-standby and distribution costs across a 30,000-customer base. New arrivals should budget 20% to 35% above an equivalent GB property and consider heat-pump or biomass heating before assuming direct electric is the right answer for a heritage Guernsey home.
Complaint about a faulty meter took five months
Reported a meter clearly running fast in January. Engineer visit booked, cancelled, rebooked. Meter eventually swapped in May and credited bill received in July. Not impressed by the timeline.
— Margaret, St Andrew
Trustpilot
Selectra expert comment
Meter-fault complaints can sit at the upper end of resolution times, partly because every engineer slot has to come from the same small island team. Lessons learned: when raising a meter-accuracy concern, ask immediately for the dispute to be logged under the GCRA-recognised complaints procedure, which gives you a clearer escalation path if resolution drifts.
Good information, fair process
Renovated an old farmhouse, needed a service upgrade and a three-phase supply for a heat pump. Survey turned up on time, quote was clear, install was on schedule. Customer service throughout the project was knowledgeable about Guernsey building requirements.
— Robert, St Martin
Trustpilot
Selectra expert comment
For projects involving three-phase supplies, heat pumps or solar export, Guernsey Electricity’s in-house engineering team is genuinely strong. They understand the island’s wiring regulations and the buy-back / export-tariff framework, which a GB-style independent installer would not. Ask for the Buy-back tariff schedule alongside the supply quote.
Selectra editorial takeaway
Reading the reviews together
Reading the six reviews together, the verdict is consistent: Guernsey Electricity does the hard things well (supply availability, complex installs, low-carbon imports) and the simple things less well (estimated bills, complaint resolution speed, tariff explanation). The 1-star and 2-star reviews concentrate on time-to-resolve issues, not on supply quality.
For Guernsey customers, the practical playbook is the same as for any small-island monopoly utility: use the walk-in office whenever possible, keep a paper trail, register for vulnerable-customer support if eligible, and escalate to the GCRA if a complaint drifts past the supplier’s own deadlines.
Selectra explains
Guernsey Electricity's online presence: expert analysis
Author: Selectra UK energy team · Updated April 2026
Guernsey Electricity’s online review footprint is modest by GB standards because it serves about 30,000 customers on a single island. The Trustpilot count sits in the low hundreds rather than the hundreds of thousands. That said, the signals across Trustpilot, Google Maps and the Guernsey Press are remarkably consistent: high marks for supply reliability and the walk-in team at Vale, lower marks for the speed of complaint resolution and estimated-bill recurrence.

Selectra expert verdict
Reading every channel together
For a state-owned small-island monopoly, Guernsey Electricity’s online reputation sits where you would expect: solid on the operational big stuff, patchy on the everyday admin. The honest customer playbook is to use the walk-in office at Vale, expect estimated bills until your meter is upgraded, and use the GCRA route for any complaint that drifts past eight weeks. Headline scores: Trustpilot 3.6/5 (about 280 reviews), Google Maps 4.0/5 (about 140 reviews). No Citizens Advice / Energy Ombudsman scores because the bailiwick sits outside the GB regulatory perimeter — comparing against GB suppliers on those tables is structurally unfair.
Reviews don't pay the bill — the tariff does.
A great supplier still costs you money if you're on a bad tariff. Compare Guernsey Electricity against every other UK supplier on the price for your actual usage.
Common questions
Guernsey Electricity reviews — frequently asked questions
Guernsey Electricity is regulated by Ofgem and bound by the Standards of Conduct that protect domestic customers. Reliability is best judged against your own usage profile: read recent reviews, check the Citizens Advice star rating for Guernsey Electricity, and confirm the supplier's customer-service hours match when you actually need to call.
Trustpilot, Google Maps and app-store reviews reflect real experiences but are often skewed toward dissatisfied customers (people only post when something goes wrong). The most balanced single rating is Citizens Advice's quarterly supplier performance table, which scores all UK domestic suppliers on complaint handling, transfers, debt and communication — and is built from regulator-supplied data, not self-reported.
Confirm the unit rate (p/kWh) for both gas and electricity, the daily standing charge, the contract length, any exit fee (typical range: £25-£75 per fuel), and whether the deal requires a smart meter. Always cross-check the headline price against several other suppliers based on your actual postcode and annual kWh consumption from a recent bill.
If you're a current or former Guernsey Electricity customer, share your experience on Trustpilot UK (search the supplier name), Google Maps (write a review on the Guernsey Electricity business profile), or the Apple App Store and Google Play if you've used the mobile app. Selectra also collects independent reviews to help future customers compare suppliers objectively.
