Fix'd Dual Family Advantage+ Explained

How Family Advantage+ works

The tariff fixes four main charges for twelve months: The unit rates determine the amount paid for each kilowatt hour consumed. Standing charges apply every day, regardless of whether the household uses any energy. Family Advantage+ remains a normal fixed energy contract. The unit rates and standing charges are fixed, but the total bill is not. A household using more electricity or gas will still pay more. Outfox explains that fixed-tariff unit rates and standing charges remain unchanged during the contract, while monthly Direct Debit payments can be adjusted if the household's consumption or account balance changes.

The current July 2026 version

Current tariff databases list the product as:

Fix'd Dual Jul26 12M v1 -- Family Advantage+

It is available as a dual-fuel monthly Direct Debit tariff across the main electricity distribution regions of Great Britain. Both standard single-rate and Economy 7 versions are listed, depending on the property's meter type and regional availability. Outfox frequently publishes new tariff versions. A June, May or earlier Family Advantage+ contract may therefore have different rates from the July 2026 product. Customers should retain the exact tariff name, version number and Tariff Information Label accepted at sign-up.

What is the "family advantage"?

The name appears to refer to a pricing profile aimed at households with relatively high gas consumption. Compared with the matching standard Fix'd Dual Jul26 12M v1 tariff, Family Advantage+ generally offers: The precise rates vary by region, but the same basic structure appears across the July tariff records. This means the tariff does not automatically save a family money. Its value depends mainly on whether the household uses enough gas to recover the additional standing-charge cost.

• A gas unit rate approximately 0.885p per kWh lower
• A gas standing charge approximately 30p per day higher
• An electricity unit rate approximately 0.977p per kWh higher
• Broadly the same electricity standing charge

Example using South East England rates

For one South East England regional record, the standard Fix'd Dual Jul26 12M v1 rates are: The corresponding Family Advantage+ rates are: The Family Advantage+ customer therefore pays 0.974p more for every electricity unit, while saving 0.885p on every gas unit. The gas standing charge is 30p a day higher. Across a complete year, the additional gas standing charge is: 30p × 365 = £109.50 That extra fixed cost is incurred before the household uses any gas.

• Electricity: 21.500p per kWh
• Electricity standing charge: 44.78p per day
• Gas: 6.510p per kWh
• Gas standing charge: 29.52p per day
• Electricity: 22.474p per kWh
• Electricity standing charge: 44.78p per day
• Gas: 5.625p per kWh
• Gas standing charge: 59.52p per day

Gas break-even point

Ignoring electricity for a moment, the household must save at least £109.50 through the lower gas rate. The saving is 0.885p for every gas kilowatt hour. The gas-only break-even point is therefore approximately: £109.50 ÷ £0.00885 = 12,373 kWh of gas a year Below that consumption, the lower gas unit rate does not recover the higher gas standing charge. Above it, the gas component begins to favour Family Advantage+. However, the electricity rate is also higher, so the true household break-even point is greater.

Including electricity consumption

Suppose a household uses: The higher Family Advantage+ electricity rate adds approximately: 3,000 × 0.974p = £29.22 The higher gas standing charge adds: 365 × 30p = £109.50 The lower gas unit rate saves: 12,000 × 0.885p = £106.20 The Family Advantage+ tariff would be approximately £32.52 more expensive in this example. For a household using 3,000 kWh of electricity, annual gas consumption would need to reach roughly 15,700 kWh before the Family Advantage+ pricing began to break even against the comparable standard version. The precise break-even figure varies by electricity consumption and regional rates.

• 3,000 kWh of electricity
• 12,000 kWh of gas

High-use household example

Consider a larger gas-heated property using: The higher electricity rate adds approximately: 3,500 × 0.974p = £34.09 The additional gas standing charge adds £109.50. The reduced gas rate saves: 22,000 × 0.885p = £194.70 The Family Advantage+ version would be approximately £51 cheaper over the year in this illustration. This shows the type of household that may benefit: a property with substantial gas demand rather than merely a household containing children.

• 3,500 kWh of electricity
• 22,000 kWh of gas

Who might use more than 15,000 kWh of gas?

Higher gas demand can arise in: The name "Family Advantage+" may suggest large-family use, but the number of occupants alone is not enough to establish suitability. A well-insulated family home could use much less gas than an older property occupied by one or two people. Annual consumption is more important than household type.

• Large detached properties
• Poorly insulated homes
• Older buildings with substantial heat loss
• Homes occupied throughout the day
• Households with several occupants
• Properties using gas for heating, hot water and cooking
• Homes maintained at higher temperatures
• Properties in colder parts of Great Britain

Regional differences

Family Advantage+ does not have one national price. For the July 2026 standard-rate version, published electricity unit rates range from approximately 21.379p to 23.752p per kWh across regional records. Electricity standing charges range considerably, from below 45p to more than 70p a day. Gas unit rates are generally between approximately 5.31p and 5.65p per kWh, while gas standing charges are around 58p to 60p a day. A household in northern Scotland can therefore receive a different annual estimate from an otherwise similar household in southern England. The tariff must be compared using the customer's postcode and actual energy consumption.

Economy 7 version

Family Advantage+ is also listed with Economy 7 pricing. These versions have: The July regional records show off-peak electricity rates around 14p to 15p per kWh, with higher daytime prices. Economy 7 is not automatically cheaper. The result depends on how much electricity is used during the off-peak period. A household with storage heaters, an immersion heater, battery storage or overnight EV charging may benefit. A household using most electricity during the day may pay more than on the single-rate version.

• A daytime electricity rate
• A lower off-peak rate
• An electricity standing charge
• The Family Advantage+ gas structure

Direct Debit and online management

Current records identify Family Advantage+ as a monthly Direct Debit tariff. Outfox's tariff terms also make Direct Debit and online account management mandatory for the relevant fixed dual-fuel products. The monthly Direct Debit is based on expected annual use, tariff prices and the account balance. Outfox says it reviews payments periodically and may propose a higher or lower amount where the account is building debt or excessive credit. An increase in the Direct Debit does not necessarily mean the fixed tariff prices have changed. It can reflect greater consumption or an account shortfall.

The £75-per-fuel exit fee

The current Family Advantage+ product carries an exit fee of £75 for electricity and £75 for gas. Leaving both supplies before the tariff's protected final period could therefore cost £150. A later tariff would need to save more than this amount over the remaining contract period before switching became worthwhile. For example, a new offer saving £200 over the remaining term would produce only £50 of net benefit after the exit fees. Customers should check the exact contract because exit-fee rules can differ between tariff versions and circumstances.

Family Advantage+ compared with standard Fix'd Dual

Both tariffs provide: The difference lies primarily in how the prices are distributed. Standard Fix'd Dual has a higher gas unit rate but a much lower gas standing charge. It also currently has a slightly lower electricity unit rate. Family Advantage+ has a lower gas unit price but a substantially higher fixed daily gas charge. Standard Fix'd Dual is therefore likely to be stronger for low and medium gas users. Family Advantage+ can become more competitive for high gas users once the lower gas rate saves enough to overcome both the higher standing charge and higher electricity cost.

• Twelve months of fixed rates
• Dual-fuel supply
• Monthly Direct Debit
• Regional pricing
• Online account management
• £75 exit fee per fuel

Is Family Advantage+ cheaper for a typical household?

Not necessarily. Current national comparison estimates place the Family Advantage+ version above the standard July Fix'd tariff for representative household consumption. One market comparison estimated approximately £1,451 a year for the standard July tariff and around £1,501 for Family Advantage+, although actual costs vary by region and personal consumption. That difference arises because representative gas use may be below the level needed to exploit the lower gas unit rate fully. A high-use property could produce a different result.

Who is most likely to benefit?

Family Advantage+ may suit a household that: It may be unsuitable for: Outfox Energy Fix'd Dual Family Advantage+ is best understood as a high-gas-use pricing option. Its lower gas unit rate can create savings, but only after the higher gas standing charge and higher electricity rate have been recovered. The correct test is mathematical rather than promotional: compare both tariffs using the household's postcode, annual electricity consumption and annual gas use. For many ordinary households, the standard Fix'd Dual tariff may remain cheaper despite the Family Advantage+ name.
