Can You Install an Oven Under an Induction Hob?
Yes, in most cases. Installing a built-in oven directly below an induction hob is one of the most common layouts in modern fitted kitchens, and both appliance types are designed with it in mind. The installation works reliably provided the correct air gap is maintained between the two units, rear ventilation is adequate, and the electrical supply is handled by a qualified electrician. Where problems arise, they are almost always the result of skipping one of these three requirements.
Key Clearance Requirements
The critical dimension in any oven-under-hob installation is the air gap between the top of the oven casing and the underside of the induction hob. This gap serves two purposes: it allows heat rising from the oven to dissipate before reaching the hob’s electronics, and it provides the airflow the hob needs to cool its own internal components during operation. Too small a gap and the hob’s thermal protection sensor will trigger, switching the hob off mid-use.
Key installation clearances: the air gap between oven and hob is the most critical dimension. Always verify exact figures against both appliance installation manuals before fitting.
The 20mm air gap cited above is the widely used general guideline, but manufacturer specifications vary. Some induction hobs require 25mm or more; a small number of models designed specifically for under-hob installation are rated for zero clearance. The only reliable source is the installation manual for your specific hob model. Using a general figure from an online article, including this one, as a substitute for the manufacturer’s own specification is a risk not worth taking when the consequence is a hob that shuts itself down or overheats.
Full Installation Requirements
Four distinct areas each need to be checked before confirming the combination will work. A problem in any one of them can make an otherwise sensible installation fail in practice.
| Requirement | Typical specification | What happens if not met |
|---|---|---|
| Air gap (oven top to hob base) | Min. 20 mm (verify in both manuals — some models require more) | Hob thermal protection sensor triggers; hob switches off during use |
| Rear ventilation | Cabinet back panel must not be fully sealed; vent openings or a ventilated back panel required | Heat accumulates behind the oven, raising ambient temperature around hob electronics; accelerated component wear and potential shutdown |
| Divider panel | Required by some manufacturers; insulates hob from oven radiated heat | Without it where specified, heat transfer through direct radiation may exceed hob’s rated operating temperature |
| Cabinet depth and width | Standard 600 mm wide, 570 mm deep cabinet for most built-in ovens; hob must not overhang the oven housing significantly | Poor fit affects ventilation channels and may prevent the oven door from opening cleanly |
| Electrical supply | Separate dedicated circuits for each appliance in most UK installations; both require hardwired or switched fused connections | Shared circuit risks tripping the breaker under simultaneous load; inadequate cabling creates a fire risk |
| Cooker hood clearance | Min. 650 mm above hob surface for electric/induction (verify in hood manual) | Hood overheats; reduced extraction performance; hood warranty may be voided |
Installation Configurations
Most kitchens fall into one of three scenarios. Each has slightly different considerations worth checking before buying.
Standard under-counter installation
A single built-in oven in a 600 mm base unit with an induction hob set into the worktop directly above. This is the configuration both appliance types are designed around. Provided the air gap, rear ventilation, and electrical supply are correct, this combination is straightforward and reliable.
Check: confirm the oven’s specified maximum top clearance temperature against the hob’s minimum underside temperature tolerance.
Tall housing with oven at mid-height
Some kitchens use a tall housing unit with the oven positioned at eye level and a separate hob on the worktop nearby. In this case the oven and hob are not directly stacked, so clearance and ventilation requirements between the two do not apply. The hob still requires adequate ventilation from the worktop cut-out and the underside of the unit.
Check: this layout separates the two appliances entirely, which simplifies electrical planning.
Matched brand pairing
Some manufacturers, including CATA, design their oven and hob ranges to work together and list approved combinations in their documentation. Using a matched pair removes uncertainty about compatibility, ventilation requirements, and warranty coverage. It does not remove the need for professional electrical installation.
Check: matched pairings are documented in the manufacturer’s installation guides; ask your retailer or check the product page.
When This Combination Does Not Work
The oven-under-hob layout is reliable in most standard kitchens, but there are specific situations where it either cannot be made to work safely or requires significant additional effort to resolve.
Watch out for these situations
- Non-standard cabinet depth. Older kitchens sometimes use 500 mm depth cabinets rather than the modern 600 mm standard. A built-in oven may not fit correctly, and the reduced depth can compromise rear airflow through the cabinet. Measure the cabinet internal depth before purchasing either appliance.
- Oven with top-venting exhaust. Some oven models vent hot exhaust air upward through the top panel rather than through the door or front. These are generally not suitable for under-hob installation, as the exhaust heat rises directly into the hob’s underside. Check the oven’s installation manual for exhaust vent location before purchasing.
- Fully sealed cabinet back panel. A kitchen unit with a solid back panel and no provision for rear ventilation will trap heat behind the oven. This is not always visible at the point of purchase and is more common in older fitted kitchens. A carpenter or kitchen fitter can add a ventilated back panel or rear vent, but this needs to be planned before installation day.
- Combined electrical load exceeds available capacity. Induction hobs commonly draw between 7 kW and 13 kW; ovens typically draw 2.5 kW to 4 kW. If the kitchen consumer unit has limited spare capacity or outdated wiring, a qualified electrician may need to upgrade the consumer unit before either appliance can be connected safely.
- Manufacturer restrictions on combinations. A small number of induction hob manufacturers specify that only ovens with an active cooling fan (not passive ventilation) may be installed below their products. This is not universal, but it is worth checking the specific hob model’s documentation rather than assuming all combinations are permitted.
Electrical Requirements
The electrical side of a combined induction hob and oven installation requires a qualified electrician in every case. This is not a job for a competent DIY enthusiast, regardless of experience, because both appliances are classed as fixed electrical equipment under Part P of the Building Regulations. Installation must be notified to and inspected by a registered installer or local building control.
In practice, most UK kitchens require two separate circuits for this combination. An induction hob typically needs a 32 A or 40 A radial circuit with appropriately rated cable and a double-pole isolator switch within reach of the hob but not above it. The oven requires its own 13 A fused connection unit or a 20 A radial circuit depending on its rated load. Both connections must be accessible for isolation without moving the appliances themselves.
The combined load of a large induction hob and a full-size oven running simultaneously can approach 15 kW to 17 kW. In older properties where the consumer unit was installed before induction hobs became common, the available capacity may simply not support this without an upgrade. An electrician will assess this before installation and advise accordingly. For more on how induction hobs work electrically and what they require from a kitchen, the guide to vented induction hobs covers the technology in detail.
All electrical work on fixed kitchen appliances must comply with BS 7671 (the IET Wiring Regulations) and be carried out or certified by a competent person registered under a Part P competent person scheme. The GOV.UK guide to building regulations approval explains when notification is required and how to find a registered electrician.
Frequently Asked Questions
This is almost always a thermal protection response. The hob’s internal temperature sensor detects that the electronics are getting too hot, typically because heat rising from the oven is not dissipating quickly enough before reaching the hob’s underside. The most common causes are an insufficient air gap between the two appliances, a cabinet back panel that is fully sealed with no rear ventilation, or a missing divider panel where the manufacturer requires one. Check the installation manual for both appliances against your actual setup and correct the ventilation before using both simultaneously again.
Not generally. Most oven and induction hob combinations from different manufacturers work together provided the clearance and ventilation requirements are met. The exception worth checking is warranty terms. A small number of manufacturers only warrant their induction hobs against heat-related failures when installed above an own-brand oven. If the combination is from two different brands, check both manufacturers’ documentation to confirm there are no approved-combination restrictions that would affect your warranty position.
It is possible but more complex. A double oven occupies a taller housing unit, typically 900 mm to 1,000 mm, and achieving the correct air gap while still positioning the hob at a comfortable worktop height requires careful planning. The taller cabinet also tends to produce more total heat output, making rear ventilation even more important. Some induction hob manufacturers specifically restrict installation above double ovens in their documentation. If you are considering this configuration, confirm it explicitly in the hob’s installation manual before purchasing the double oven.
In principle, yes, subject to the same clearance and ventilation requirements. In practice, gas oven installations involve a gas connection that adds complexity to the overall fitting job and requires a Gas Safe registered engineer rather than just an electrician. The induction hob itself still requires its own dedicated electrical circuit regardless. Some kitchen fitters prefer to avoid this combination simply because coordinating the two separate trades adds cost and scheduling complexity. There are no fundamental incompatibilities between the two appliance types at a technical level.
Not when the installation is done correctly. Induction hobs are designed and tested with the expectation that an oven may be installed below them, and the required air gap and ventilation specifications are set with that heat output in mind. The risk is not that a correctly installed hob will be damaged, but that an incorrectly installed one will trigger its thermal protection repeatedly, causing inconvenient shutdowns and potentially reducing the lifespan of the hob’s electronics over time through repeated thermal stress cycles.
In most UK homes, yes. The combined current draw of an induction hob and oven is too high to share safely with other kitchen circuits. An induction hob typically requires a dedicated 32 A or 40 A radial circuit; a built-in oven requires either a 13 A fused spur or a 20 A radial circuit, depending on the oven’s rated power. A qualified electrician will assess your consumer unit’s available capacity and advise whether new circuits need to be run from the distribution board. This assessment should happen before finalising your appliance purchases, not on the day of installation.
Summary
Installing an oven under an induction hob is a standard and reliable kitchen configuration when done correctly. The key points to carry away:
- Both appliances must be rated for built-in cabinet installation. Check both installation manuals before purchasing.
- A minimum air gap of around 20 mm between the oven’s top panel and the hob’s underside is the widely used guideline, but your specific hob model may require more. Always use the manufacturer’s figure.
- Rear ventilation is essential. A fully sealed cabinet back panel traps heat and will cause the hob’s thermal protection to trigger.
- A divider panel is required by some manufacturers and should not be omitted where specified.
- Both appliances need separate dedicated electrical circuits. This work must be carried out by a qualified electrician and notified under Part P of the Building Regulations.
- If the hob shuts off when both appliances run simultaneously, the cause is almost always insufficient ventilation, not a fault with either appliance.
