Best For

  • Meal prep where two different dishes need different settings but should finish together, such as a main and a side
  • Batch cooking larger portions of fries or vegetables using the large mesh tray
  • Kitchens with a fixed, ventilated worktop spot able to accommodate a 38.7 x 36 x 36.7cm, 8.6kg appliance permanently
  • Cleaning routines that rely on a dishwasher rather than hand-washing multiple trays and baskets

Avoid If

  • Kitchens with limited or shared counter space, given the appliance's footprint and weight
  • Purchases based solely on the £65-a-year saving or 99.5% oil-reduction figures, since both are manufacturer-derived and not independently verified
  • Single-portion cooking needs, where the dual-zone split and extra accessories add bulk without a corresponding benefit
  • Buyers requiring independently verified noise-level or cooking-evenness data, as none has been provided

Quick Verdict

Advantages

  • The Sync function lets each 5.5L zone run a different food on a different setting while still finishing at the same time, addressing the common single-dish limitation of standard air fryers.
  • Ten built-in presets and six cooking modes, air fry, turbo crisp, bake, grill, roast and reheat, are supported by a single appliance, reducing the need for separate kitchen tools.
  • The included large mesh tray is designed for batch cooking bigger portions of fries or vegetables, useful when the two zones are combined for one larger dish rather than kept separate.
  • All eight accessories, including the cooking baskets, mesh trays and roasting trays, are dishwasher-safe, simplifying routine cleaning after multi-zone cooking.
  • An auto shutoff function is included as a stated safety feature.

Limitations

  • The £65-a-year energy saving over an oven is based on Breville's own internal testing against a single frozen-chip scenario, not independently verified, so it may not reflect other households' cooking habits.
  • The claimed 99.5% oil reduction is measured against Breville's own smaller 3L fryers rather than other manufacturers' models, so it does not indicate how the Halo Flexi compares with air fryers from other brands.
  • At 38.7 x 36 x 36.7cm and 8.6kg, the appliance needs a permanent, ventilated counter position rather than being suited to occasional storage-and-retrieval use.
  • No independent test data on cooking evenness or the claimed 360° air circulation performance is available, making it difficult to verify crisping results from the available information.
Breville Halo Flexi Air Fryer VDF138: dual-zone cooking, unverified savings — product image

Overview

A dual-zone 11L compartment split into two 5.5L sections is the core trade-off here: buyers gain the ability to cook two different foods on two different settings using the Sync function, or run matched batches with Match, but they also take on a large, heavy appliance that needs a permanent counter position. Breville's £65-a-year energy saving and 99.5% oil-reduction figures are both drawn from the manufacturer's own internal testing rather than an independent source, so they are best treated as indicative rather than guaranteed. Eight dishwasher-safe accessories and ten built-in presets point to an appliance designed to cover several cooking tasks at once, which may offset the size and weight for households that would otherwise use multiple separate gadgets.

Performance

Splitting the 11L compartment into two 5.5L zones, combined with the Sync and Match functions, is aimed at a specific problem: most single-basket air fryers can only cook one dish at a time, so a main and a side have to be timed separately or served apart. According to the manufacturer, Sync allows each zone to run a different food on a different setting and still finish together, while Match runs identical settings in both zones at once for batch cooking. This is most relevant for households that regularly prepare a meal with more than one component. The ten cooking presets and six modes, air fry, turbo crisp, bake, grill, roast and reheat, together with the large mesh tray for bigger batches of fries or vegetables, suggest the appliance is intended to cover tasks that would otherwise need several separate tools. No independent data on cooking evenness or the effectiveness of the stated 360° air circulation has been supplied, so how consistently the zones crisp or brown food cannot be assessed from the available information. Breville's claim that the appliance saves £65 a year against oven cooking is based on the company's own internal testing rather than independent verification; the practical implication is that actual savings will vary with how often and how the appliance is used, and this figure should not be treated as a guaranteed outcome.

Design & Build

At 38.7 x 36 x 36.7cm and 8.6kg, this is a substantial dual-zone appliance rather than a compact single fryer, and the footprint needs to be checked against available worktop space before ordering. The weight and size point towards a fixed, permanent position on the counter rather than an appliance that gets moved in and out of a cupboard for occasional use. Because the cooking method relies on air circulation, clearance around the unit for ventilation is also worth factoring into any placement decision, alongside the counter footprint itself.

Installation

Before buying, it is worth confirming counter space of at least 38.7 x 36cm plus clearance for air vents, checking that the mains supply matches the stated 220V rating and can support a 2400W load, and planning for a fixed or semi-permanent position given the 8.6kg weight rather than frequent lifting in and out of storage.

Energy Efficiency

The only efficiency evidence provided is Breville's claim of a £65-a-year saving compared with cooking the same meal in a 70L A-rated electric fan oven, based on internal testing of 300g of frozen chips at October 2023 energy prices. This is a single manufacturer-run comparison rather than an independently verified efficiency rating, and no wattage-based running-cost or kWh consumption figure is given beyond the 2400W power rating, so buyers cannot independently calculate running costs for their own usage patterns from what has been supplied.

Maintenance

The two cooking baskets, two small mesh trays, large mesh tray, two small roasting trays and large roasting tray are all listed as dishwasher-safe, which simplifies cleaning after multi-zone use. Dishwasher-safe status applies to these removable accessories rather than the main unit, so the housing and interior should be wiped down by hand, and the auto shutoff function is worth confirming is understood as a safety feature rather than something that aids cleaning.

Best For

  • Meal prep where two different dishes need different settings but should finish together, such as a main and a side
  • Batch cooking larger portions of fries or vegetables using the large mesh tray
  • Kitchens with a fixed, ventilated worktop spot able to accommodate a 38.7 x 36 x 36.7cm, 8.6kg appliance permanently
  • Cleaning routines that rely on a dishwasher rather than hand-washing multiple trays and baskets
  • Replacing several separate cooking presets and tools with a single appliance covering air frying, turbo crisping, baking, grilling, roasting and reheating

Not Suitable For

  • Kitchens with limited or shared counter space, given the appliance's footprint and weight
  • Purchases based solely on the £65-a-year saving or 99.5% oil-reduction figures, since both are manufacturer-derived and not independently verified
  • Single-portion cooking needs, where the dual-zone split and extra accessories add bulk without a corresponding benefit
  • Buyers requiring independently verified noise-level or cooking-evenness data, as none has been provided

Frequently Asked Questions

Can I cook two completely different foods at once?

Yes. The Sync function is designed to cook two foods on two different settings so they finish together, while the Match function runs both 5.5L zones at the same time and temperature.

Will this really save £65 a year on energy compared with my oven?

That figure comes from Breville's own internal testing, comparing 300g of frozen chips against a 70L A-rated electric fan oven using October 2023 energy prices. It has not been independently verified, so actual savings will depend on individual usage.

How much oil does it use compared with a standard air fryer?

Breville states it uses 99.5% less oil than its own standard 3L air fryers. This is a manufacturer comparison against Breville's own smaller models, not an independently tested figure, and no comparison with other brands is given.

Are the trays and baskets dishwasher-safe?

Yes. The full accessory set, including the cooking baskets, mesh trays and roasting trays, is listed as dishwasher-safe. The main housing should be wiped down by hand.

Will it fit on my counter?

It measures 38.7 x 36 x 36.7cm and weighs 8.6kg, so it needs a reasonably large, stable, permanent spot rather than a small or shared counter area.

Our Verdict

Worth Considering · 58 / 100

The dual 5.5L zones, Sync and Match functions, and eight dishwasher-safe accessories mean it can genuinely replace several separate kitchen tools for households that regularly cook multi-component meals. Its headline running-cost and oil-reduction figures come from Breville's own internal testing rather than independent verification, so the scale of any real-world saving remains uncertain. It suits households that want to cook two different dishes on two different settings at once and have a fixed, ventilated spot for a substantial 8.6kg worktop appliance. It is less suited to kitchens with limited counter space, those who only ever cook single portions, or buyers who need independently verified energy and oil-use data before committing to a specific saving figure.
