NEFF N70 Built-In Compact Oven with Microwave Function
A 45-litre built-in compact oven and 900 W inverter microwave in one Graphite-Grey housing, with 17 heating methods, Air Fry and Home Connect app control.
The C24MR21G0B combines a proper compact oven with a 900 W microwave in a single built-in unit just 45.5 cm high. It suits kitchens where space is tight, or works as a second oven beside a main one, giving you baking, grilling, roasting and microwave speed from one Graphite-Grey appliance.
The standout is how the two halves work together. Inverter Technology feeds in microwave power gradually rather than in blasts, and microwave modes can be combined with heating methods such as the full width grill or hot air grilling, so a midweek gratin browns properly in a fraction of the usual time.
Ideal For
At 45.5 cm high and 59.6 cm wide, it delivers oven, grill and microwave from one housing, freeing worktop space and sparing you a separate countertop microwave altogether.
Fitted above or beside a main oven, it handles sides, desserts and quick reheats on busy days, leaving the larger cavity free for the centrepiece dish.
Seventeen heating methods and combined microwave cooking shorten everyday dinners, while Home Connect lets you check and adjust the oven from your phone elsewhere in the house.
Key Features
Five power levels from 90 W up to boost, delivered gradually by Inverter Technology for even heating without scorched edges or cold centres.
Circulating air, conventional heat, full and half width grills, dough proving, plate warming and more cover everything from weekend roasts to delicate bakes.
A dedicated Air Fry setting works with the included Air Fry & Grill tray for crisp results without another appliance taking up the worktop.
The touch display keeps settings legible at a glance, with temperature proposals, an actual temperature readout and a heating-up indicator built in.
Connect over Wi-Fi to control the oven from the app, use the Oven Assistant, or cook by voice through a compatible voice assistant.
The damped drop-down door opens and closes gently, and triple-glazed CoolTouch glazing helps keep the outer surface of the door cooler in use.
One cavity, two ways of cooking
Most compact combis feel like a microwave first and an oven second; this one is a full oven from the start. You get 17 heating methods, three shelf positions and a 45-litre cavity with LED lighting, then a 900 W microwave layered on top. Use each mode alone, or combine microwave power with the grill or hot air so weeknight dishes finish sooner while still browning the way oven food should.
Inverter power that heats gently
Conventional microwaves pulse full power on and off. Inverter Technology regulates output continuously instead, and in longer sessions caps power at 600 W to treat food more gently. In practice that means defrosting without cooked grey edges, and reheated dinners that come out evenly hot rather than scalding in one spot and cold in another. Five settings from 90 W to boost cover delicate tasks through to rapid heating.
Designed to be lived with every day
The details are where this oven earns its keep. EasyClean softens baked-on residue with heat and water so a wipe finishes the job. Home Connect brings the Oven Assistant, remote monitoring and voice control to your phone. The SoftClose door cushions itself shut, the control panel locks against small fingers, and automatic safety switch-off, a residual heat indicator and a door contact switch are all standard. A combination grid, universal pan and Air Fry & Grill tray are included, so it arrives ready to cook rather than waiting on accessories.
How It Compares
| Kitchen Need | NEFF Technology | Practical Benefit |
|---|---|---|
| Quick weeknight dinners | Combined microwave and oven modes | Microwave speed with grill or hot air browning cuts cooking time without sacrificing texture or colour. |
| Small kitchens | 45 cm compact housing | Oven, grill and 900 W microwave occupy one built-in niche, with no countertop microwave needed. |
| Gentle defrosting | Inverter Technology | Power arrives gradually and is capped at 600 W in longer runs, so food thaws evenly throughout. |
| Home baking | Dough proving and 17 methods | Dedicated proving, circulating air and conventional heat handle bread, cakes and delicate bakes with real control. |
| Crispy favourites | Air Fry setting with tray | The included Air Fry & Grill tray crisps chips and vegetables without a separate gadget on the worktop. |
| Hands-full cooking | Home Connect voice control | Adjust settings or check progress from the app or a voice assistant while you get on with prep. |

The Verdict
Strengths
- Full 45-litre oven and 900 W microwave in one
- 17 heating methods including a dedicated Air Fry setting
- Inverter Technology for even, gentle microwave power
- Home Connect app control with Oven Assistant and voice
- SoftClose drop-down door with CoolTouch glazing
- EasyClean programme for fast, energy-saving cleaning
- Combination grid, universal pan and Air Fry tray included
Considerations
- Requires a hardwired 3.6 kW connection on a 16 A fuse, so installation is a job for a qualified electrician rather than plug-and-go.
- The oven's temperature range tops out at 230 °C, and cleaning is the EasyClean soak programme rather than pyrolytic self-cleaning.
- This is a built-in appliance for a 45 cm compact niche with suitable housing; it cannot stand alone on a worktop.
