See Manx Utilities tariffs Compare all providers
The Isle of Man is a Crown Dependency outside the GB Energy Price Cap. Manx Utilities tariffs are approved annually by Tynwald (the Isle of Man parliament) following review by CURA. The April 2026 update applied the CPI-linked unit-rate adjustment of 1.5% (capped from 2.9%) and a 5.7% uplift on the standing charge, taking the standard domestic standing charge from 24.1 p/day to 25.5 p/day. All unit rates below include 5% VAT at the domestic rate but exclude the £1.50 quarterly e-billing + Direct Debit discount and the 1% prompt-payment discount on SmarterPAYG.

Selectra expert

Which Manx Utilities tariff fits you, and what will you actually pay?

Manx Utilities publishes one standard domestic tariff plus four time-of-use specials (Comfy Heat, EV, Sustainable Generation, SmarterPAYG) and a basic tariff for households who opted out of smart meters. The right pick depends on how you use electricity: pure flat use stays on Standard Domestic; an electric heating or EV household saves with a two-rate tariff; a property with PV or wind earns with the Sustainable Generation bolt-on. The headline rate (29.5 p/kWh) is broadly in line with the GB price cap, but the standing charge is materially lower than most GB suppliers.

Standard Domestic

variable · smart meter

Best fit if — Most Isle of Man households, the default tariff once a smart meter is installed. Simple, single-rate, no time-of-use rules.

Skip if — You heat your home or hot water electrically (Comfy Heat is cheaper) or you charge an EV at home (EV tariff cuts off-peak charging by ~10 p/kWh).

What you'll actually pay

29.5 p/kWh + 25.5 p/day standing charge. A 3,800 kWh/year household pays about £1,215 a year including VAT.

The right starting point for any standard Isle of Man household. Set up Direct Debit + e-billing for the £1.50 quarterly discount.

Basic Domestic (no smart meter)

variable · legacy meter

Best fit if — Households who have actively opted out of having a smart meter installed.

Skip if — You can have a smart meter, the Standard Domestic standing charge is £178/year lower for the same unit rate.

What you'll actually pay

29.5 p/kWh + 74.3 p/day standing charge. A 3,800 kWh/year household pays about £1,393 a year, about £178 more than Standard Domestic.

Only chosen by households actively opting out of smart metering. Reconsider that decision, the standing-charge gap is substantial over a year.

SmarterPAYG (prepayment)

prepayment · smart-prepay

Best fit if — Customers who prefer to pay-as-you-go using the SmarterPAYG app or top-up retailers. Same unit rate as Standard Domestic, with a 1% prompt-payment discount on top.

Skip if — You can manage Direct Debit on Standard Domestic, the £1.50 quarterly e-billing discount + tariff stability is usually preferable.

What you'll actually pay

29.5 p/kWh + 25.5 p/day standing charge, with 1% prompt-payment discount on units consumed.

A modern smart-prepay product, useful for budgeting customers and the rental market. Pricing is structurally fair vs Standard Domestic.

Comfy Heat (DT / DT1)

variable · two-rate

Best fit if — Households where electricity is the primary heating fuel (no oil, no gas, no hybrid heat-pump). Off-peak rate of 17.4 p/kWh in the 6 hours per day rewards storage heating and heat-pump pre-heat.

Skip if — Any part of your property is heated by oil, gas or a hybrid system, you do not qualify.

What you'll actually pay

29.5 p/kWh peak / 17.4 p/kWh off-peak + 25.5 p/day standing charge. An all-electric household using 8,500 kWh with 50% off-peak shift pays about £2,090 a year.

A genuine winner for all-electric heating households. Pre-heat the slab or storage cylinders during the off-peak windows to maximise the saving.

Electric Vehicle (domestic)

variable · two-rate · EV-only meter

Best fit if — Households with a home EV charger and off-road parking, willing to install a separate EV-only meter. Off-peak rate of 19.7 p/kWh between midnight and 7 a.m. UTC.

Skip if — You charge mainly at work or on public chargers, the meter install cost won’t pay back.

What you'll actually pay

29.5 p/kWh peak / 19.7 p/kWh off-peak + 25.5 p/day standing charge. A 6,000 mile/year EV charging at home overnight saves about £120/year vs Standard Domestic.

Worth installing if you can guarantee overnight charging. Manx Utilities monitors fair usage on this tariff, the EV meter is the audit trail.

Sustainable Generation (DSG export)

export bolt-on · PV/wind

Best fit if — Households with PV, wind or hydro generation up to 10 kW. Manx Utilities pays 9.8 p/kWh for every unit exported. Stacks on top of any import tariff.

Skip if — Your generation system is not G98/G99 compliant or your network study has not been completed.

What you'll actually pay

9.8 p/kWh paid to you for exported units; standard 25.5 p/day standing charge on the import side. A 4 kW PV array generating 4,000 kWh/year with 50% export earns about £195/year.

A clean, fair export tariff, lower than the GB Smart Export Guarantee headline rates but with no fixed-term lock-in. Worth combining with a battery to maximise self-consumption first.

Standard Commercial (NA / NC)

business · flat rate

Best fit if — Most commercial premises, offices, shops, light industry. Same unit rate and standing charge as Standard Domestic but billed at 20% commercial VAT.

Skip if — Your business uses electric heating as primary heat, Commercial Plus has a two-rate structure that rewards off-peak use.

What you'll actually pay

29.5 p/kWh + 25.5 p/day standing charge, billed at 20% commercial VAT.

The default commercial pick. Set up Direct Debit + e-billing for the £1.50 quarterly discount; review annually if usage profile changes.

Commercial Plus

business · two-rate · electric-heating

Best fit if — Commercial premises where electric heating is the primary fuel, with balanced load and power factor 0.9 or better, supply 10 kW single-phase or 50 kW three-phase max.

Skip if — Your business does not run electric heating, or the heating load is below 6 kW, you won’t qualify.

What you'll actually pay

29.5 p/kWh peak / 17.4 p/kWh off-peak (11 p.m.-7 a.m.) + 25.5 p/day standing charge, billed at 20% commercial VAT.

A targeted niche, suits a small commercial heat-pump installation or storage-heating workshop. Direct Debit required.

All Manx Utilities domestic unit rates include 5% VAT at the domestic rate. Commercial rates exclude 20% commercial VAT. Direct Debit + e-billing customers receive an extra £1.50 quarterly discount. SmarterPAYG customers receive a 1% prompt-payment discount on units consumed. Tariff schedule effective 1 April 2026 (CPI-linked +1.5% on units, +5.7% on standing charges) per Tynwald approval.

How to compare UK tariffs

Three numbers that decide your bill

  1. 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. 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. 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.

Common questions

UK energy tariffs — frequently asked questions

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.
