Outfox Energy Fix'd Dual 12M is a twelve-month fixed-price tariff for households that want the same supplier to provide both electricity and gas. The tariff fixes the electricity and gas unit rates and daily standing charges for the contract term. The total amount paid is not fixed because the bill still depends on how much energy the household uses. Current July 2026 tariff records list the standard Fix'd Dual Jul26 12M v2 product and separate Family Advantage+ variants. The current standard twelve-month tariff carries an early exit fee of ยฃ75 for each fuel, meaning a dual-fuel customer could face a combined charge of ยฃ150 for leaving early. This guide was checked on 11 July 2026.
The tariff contains four main prices: The electricity unit rate The electricity standing charge The gas unit rate The gas standing charge The unit rates determine how much the customer pays for each kilowatt hour consumed. The standing charges are applied every day while each supply remains active, including days when the household uses little or no energy. Outfox's general terms define a fixed tariff as one where the unit rates and standing charges remain unchanged for the agreed tariff term. They also make clear that the Direct Debit itself is not fixed because the payment must still reflect actual and expected consumption. The twelve-month period normally begins from the tariff or supply start date shown in the customer's contract.
A fixed tariff provides price certainty, not a guaranteed annual bill. If a household uses more gas during a cold winter, its gas bill will rise even though the gas unit rate has not changed. The same applies where electricity use increases because of an electric vehicle, home working, an immersion heater, electric heating or additional occupants. For example, a household using 3,000 kWh of electricity will pay less than the same household using 5,000 kWh, even where both are charged at exactly the same fixed unit price. Outfox calculates the monthly Direct Debit from expected annual consumption, the applicable tariff rates and the account balance. It may divide the annual estimate into twelve equal payments or use a seasonally weighted arrangement with larger winter payments and lower summer payments.
Outfox regularly creates new tariff versions as market prices and regional costs change. The name normally contains: The tariff family The month and year of release The contract length A version number A current example is Fix'd Dual Jul26 12M v2. A customer joining a different version may receive different electricity and gas prices, even where both products are described as Fix'd Dual 12M. The version number is therefore important. Customers should retain their welcome pack and Tariff Information Label so they can identify the exact rates, exit fees and contract dates accepted. Outfox's tariff-information page contains many historical and current versions, reflecting repeated product releases rather than one permanent national tariff.
Outfox does not apply one national electricity price to every customer. Electricity rates and standing charges vary between distribution regions across Great Britain. A household in northern Scotland can therefore receive a different quotation from a similar household in London, the Midlands or southern England. Gas rates can also vary through the tariff quotation, while meter type and product version may affect the final offer. The customer should compare the complete annual cost rather than concentrating on one advertised rate. A low electricity unit price may be partly offset by a higher standing charge. This is particularly important for a low-use household, where standing charges form a larger proportion of the annual bill. The most accurate calculation uses the customer's postcode, meter type and actual annual electricity and gas consumption.
Fix'd Dual 12M requires Outfox to supply both electricity and gas. It is not intended for a household wanting Outfox to supply electricity while keeping gas with another company. Outfox's tariff-specific terms describe the fixed dual-fuel product as requiring both supplies to remain with the company. They also state that the customer must pay by Direct Debit and manage the account online. A customer who switches one fuel away or cancels the required Direct Debit can lose eligibility for the tariff. Outfox may move the remaining supply onto another product and apply the relevant exit charges. Households wanting only electricity should compare Outfox's separate Fix'd Elec range.
The tariff is designed for customers paying monthly by Direct Debit. Outfox's general terms describe monthly Direct Debit payment in advance and online account management as the standard arrangement for its tariffs. The payment is usually based on estimated annual use divided across the year. Customers receive bills and account information through the online portal. Regular meter readings remain important. A working smart meter may send them automatically, while a traditional meter requires the customer to submit readings. If readings are missing, the monthly statement can contain estimated consumption. A later actual reading may then create a correction, changing the account balance and Direct Debit. A smart meter is useful but the standard Fix'd Dual tariff is not a time-of-use product. The ordinary fixed tariff does not require electricity to be consumed during special overnight periods.
Outfox's fixed dual-fuel terms describe the standard Fix'd product as a single-rate electricity tariff. The supplier may be able to support a property with a two-rate meter, but the tariff can still charge electricity through one tariff rate rather than providing a separate Economy 7 night price. A household with storage heaters or substantial overnight electricity consumption should check this carefully. Moving from a genuine Economy 7 tariff to a single-rate fix could increase costs where a large proportion of electricity was previously bought at a cheaper night rate. The comparison should use separate day and night consumption figures before assuming that a fixed single-rate product is better.
Current July 2026 records show an exit fee of ยฃ75 for electricity and ยฃ75 for gas. A dual-fuel customer leaving both supplies early could therefore be charged ยฃ150. The fee affects whether a later switch is worthwhile. Suppose another supplier offers a tariff expected to save ยฃ200 during the remaining contract period. After subtracting the ยฃ150 Outfox exit fees, the effective saving would be only ยฃ50. If the alternative tariff saved ยฃ120, switching early would cost more than remaining on the existing tariff. The calculation should use only the expected saving during the remaining contract period, not the alternative tariff's full twelve-month headline saving.
A new customer has a fourteen-day cooling-off period. Outfox states that no tariff exit fee applies when the customer cancels within that period. The household remains responsible for any electricity and gas consumed, together with standing charges for the time Outfox supplied the property. Because energy switching can complete quickly, the supply may already have transferred before the customer changes their mind. The customer may then need to arrange a return to the previous supplier or a switch to another company.
Outfox's general terms state that fixed-tariff customers receive at least 49 days' notice before the tariff expires. The customer can leave without a tariff exit penalty where the new supplier's supply start date falls within the final 49 days of the contract. The practical date should be confirmed from the renewal notice because it is the new supplier's start date, rather than simply the date on which the switch application is submitted, that matters. Customers should compare renewal offers before the existing tariff ends rather than waiting until they have automatically moved onto a variable tariff.
If the customer does not choose a new tariff, Outfox says the account is automatically moved onto its standard variable tariff when the fixed term expires. The new variable rates may be higher or lower than the expired fixed prices. The standard variable tariff has no fixed rate protection, so its prices can change with the Ofgem price-cap periods. A customer should review: Outfox's new fixed offers The Price Cap Tracker Fox Standard Other suppliers' tariffs Any electricity-only or EV product now relevant to the home The household's energy needs may have changed during the year, making the previous tariff structure less appropriate.
From July 2026, standard variable prices increased substantially under the Ofgem price cap. Outfox explains that customers on fixed tariffs normally continue paying their contracted unit rates and standing charges until the tariff ends, rather than moving onto the updated variable prices. This is the main benefit of Fix'd Dual 12M. A customer who fixed below later variable rates can avoid the increase for the remainder of the contract. The price cap does not restrict an existing fixed tariff in the same way it controls a supplier's standard variable tariff. The customer instead pays the prices agreed when joining.
The disadvantage is that a fixed tariff does not normally become cheaper when variable prices fall. A household on Fox Standard or the Price Cap Tracker may receive lower rates when the Ofgem cap decreases. A customer on Fix'd Dual 12M remains on the agreed fixed rates until the contract ends unless they switch and pay any applicable exit fees. The tariff therefore represents a trade-off. The customer gains protection from price increases but gives up automatic access to future price reductions.
Outfox's Price Cap Tracker is also a twelve-month contract, but its prices move with the Ofgem cap. The tracker currently promises a discount against the applicable cap, while Fix'd Dual provides fixed unit rates and standing charges. Fix'd Dual may be more suitable where the customer believes prices could rise and values predictable rates. The tracker may be stronger where prices fall because its rates can decrease during the contract. Both products currently carry significant exit fees, so neither provides the same flexibility as Fox Standard.
Outfox also offers a twenty-four-month Fix'd Dual tariff. Current July 2026 tariff records show a ยฃ100-per-fuel exit fee on the 24-month version, compared with ยฃ75 per fuel on the twelve-month tariff. The longer tariff provides two years of price protection but increases the risk of remaining locked into uncompetitive rates if the market falls. The twelve-month product allows the customer to reassess the market sooner and carries a smaller potential exit cost. The correct choice depends on the price difference between the offers and the household's expected circumstances.
Outfox Fix'd Dual 12M may suit a household that: Uses both electricity and mains gas Pays by monthly Direct Debit Can manage its account online Wants twelve months of fixed rates Expects to remain at the property Is unlikely to switch supplier during the term Values certainty more than complete flexibility The tariff may be less suitable for someone expecting to move, separate their fuel suppliers or install technology that could make a specialist tariff more valuable. It may also be unsuitable for a household with substantial Economy 7 night consumption if the fixed offer charges all electricity at one rate. Outfox Fix'd Dual 12M offers straightforward one-year price protection. Its value depends on the regional quotation, the household's actual consumption and whether the customer remains long enough to avoid the ยฃ150 combined exit charge.
