Before you get excited: this article is information only, not advice. Flush-mounted hobs are fixed appliances: the electrical connection must be made by a qualified electrician (Part P registered in England and Wales), the worktop cut-out should be done by an experienced fabricator, and you must confirm your home’s circuit capacity before buying anything. If your flat doesn’t have a 32-amp cooker circuit, a built-in hob of any kind is not a DIY weekend project.
Flush Induction Hobs: The Hidden Cooker Trend
Walk into a showroom kitchen in 2026 and you’ll see it everywhere: a worktop that looks like a plain slab of stone or quartz — no visible hob, no protruding controls. Then the owner touches a spot on the surface, a zone glows briefly, and a pan starts boiling. That’s the “hidden cooker”: a flush-mounted induction hob built into the worktop so it sits completely level with the surrounding surface. When it’s off, it’s effectively invisible.
It’s the current cool thing in UK kitchens, and easy to see why: a seamless look, easier cleaning, a futuristic feel. But there’s a hard electrical reality to confront. These hobs need a dedicated 32-amp circuit, professional hardwired installation, and a worktop that can be precision-cut. For renters and older flats, that’s usually a dealbreaker. Let’s look at what these hobs are, what they cost, and whether there’s a version you can actually have.
What Is a Flush or Fully-Integrated Induction Hob?
A regular built-in induction hob is a “drop-in” unit: it sits in a cut-out in the worktop, with the glass resting on top of the worktop edges, slightly proud of the surface. There’s a visible rim and a small gap around the edge where crumbs and water collect.
A flush-mounted hob (also called “fully integrated” or “frameless flush”) is installed so the top of the glass sits exactly level with the worktop surface. The worktop is cut to a precise depth, the hob is dropped in, and the surrounding stone or quartz is machined so there’s no lip at all. Run your hand across and you feel one continuous flat surface. On premium models the controls are hidden too — touch points printed subtly on the glass, invisible until the hob is powered on.
In one line: a drop-in hob sits on the worktop; a flush hob sits in it. Induction makes this possible — a coil under the glass heats the pan directly, so the glass can be thin, flat, and level with its surroundings.
The Benefits: Why People Pay For It
The flush hob isn’t just about looks, though looks are the headline:
- Design. The worktop reads as one material — stone, quartz, or solid surface. No glass lip, no rim, no visual break.
- Easier cleaning. No rim means no ledge for crumbs and washing-up water to collect in. You wipe the whole surface with one cloth.
- No protruding controls. Nothing to break or catch, and a surface that looks as clean switched off as switched on.
- Safety and accessibility. Nothing for children to grab, the surface stays cool except where a pan is sitting, and most hobs shut off automatically when the pan is lifted. For anyone with limited grip, not twisting a knob is a real plus.

Who Makes Them
Flush mounting is now filtering into mainstream UK showrooms. The brands you’ll see, in rough order of price:
| Brand | What they’re known for | Rough price range (hob only) |
|---|---|---|
| AEG | Solid mid-range flush hobs — a common first step into the hidden-hob look | £400 – £900 |
| Neff | Well-known in UK kitchens; flush hobs focused on flexible zones and easy controls | £500 – £1,100 |
| Bosch | Flush models with flexible cooking areas and strong build quality | £500 – £1,200 |
| Siemens | The fléxInduction range — flexible zones that merge so you can place pans anywhere across a large area | £700 – £1,500 |
| Miele | Premium build, precise temperature control, long warranty expectations | £1,000 – £2,000+ |
| Bora | The premium outlier: hobs with built-in downdraft extraction — steam and smells are sucked down through the hob, so you don’t need an overhead hood at all | £2,000 – £5,000+ |
That last one — Bora-style integrated downdraft extraction — is the premium version of the whole concept: no hood, no chimney, no ducting above the worktop. We’re deliberately not quoting model numbers or exact specs, because retailers’ ranges change constantly. The pattern is what matters: the more premium the brand, the more you pay for the flush fit, the flexible zones, and (in Bora’s case) the extraction.
How the Induction Zones Actually Work
Flush hobs use the same induction tech as any induction hob, but the hidden look leans on two features:
- Flex zones. Instead of fixed circles, a flex zone is one large coil area that detects where your pan is and activates only that part of it. Small pan in the corner, griddle across the middle, two pans side by side — the hob heats exactly where needed. This is what lets a flush hob look like a blank slab rather than a hob with four marked circles.
- Pan detection and power management. The hob only energises where a ferromagnetic pan is sitting, and it balances power across active zones so it never exceeds the circuit’s limit. Lift the pan and the zone switches off.
That power management is also why a 32-amp circuit is required — and why a standard socket circuit isn’t enough.
What Installing One Really Involves
A flush hob is not a like-for-like swap for an old drop-in unit. It’s a three-part project:
- The worktop cut-out. Because the hob must sit dead level, the cut-out needs machining to exact depth — a router job on laminate, but on stone or quartz it means a fabricator cutting and polishing the piece to spec. Retrofitting into an existing stone worktop can mean machining in place or replacing the whole worktop.
- The electrical circuit. The non-negotiable one. A full-size flush induction hob draws up to roughly 7kW at full load, so it needs a dedicated circuit — typically 6mm² cable on a 32-amp breaker, feeding a cooker switch on the wall. That means a new circuit from your consumer unit, run by a qualified electrician and signed off under Part P of the Building Regulations. It is hardwired; there is no plug.
- The labour. Two trades, not one: a worktop fabricator and an electrician. Add ducting or external venting if you’re going for downdraft extraction.
As a working ballpark, £800–£3,000+ installed:
| Element | Typical range |
|---|---|
| Hob itself (AEG through Miele, not Bora) | £400 – £2,000 |
| Worktop cut-out / fabrication on stone or quartz | £100 – £400 (more if the worktop must be replaced) |
| New 32A circuit, 6mm² cable, cooker switch, Part P certification | £300 – £600 |
| Downdraft extraction version (Bora-style) | £2,000 – £5,000+ all in |

The Catch for Renters and Older Flats
Here’s the bit that matters for most readers of this site. A flush hob needs a 32-amp dedicated circuit. Most older UK flats — and virtually all rented kitchens — were never wired with one. If your consumer unit has no spare 32A breaker, if there’s no cooker switch on the wall, or if the only thing in the kitchen is a socket ring on 2.5mm² cable, you cannot have a flush hob without a new circuit first. In a rental, that means landlord permission, a Part P electrician, and quite possibly a consumer unit upgrade before anyone talks about worktops. Realistically, that’s not happening in a property you don’t own.
If you’re not sure what you’ve got, our wiring and breaker identification guide shows you how to check the breaker, cable size, and era of your installation in about ten minutes — no tools required.
But here’s the good news, and it’s the whole point of this site: you can get most of the practical benefits of the hidden-hob idea without any wiring at all. A portable 13-amp induction hob — the plug-in countertop kind, roughly £35–£150 — gives you the same flat, wipe-clean surface, the same pan detection, the same instant heat, and the same “nothing protruding” usability. It sits on your worktop rather than in it, so it isn’t invisible, but it’s thin, flat, and genuinely close in feel. No electrician, no landlord, no 6mm² cable, no Part P.

And if you’re wondering whether one can genuinely replace a built-in hob day to day, our portable-vs-built-in comparison is the honest answer.
What to Check Before You Buy Anything
Whether you’re going for the flush hob or the plug-in compromise, work through this checklist first:
- Worktop material. Flush mounting needs a worktop that can be machined to a precise depth — stone and quartz are ideal, thick solid-surface works, cheap laminate is risky. Check with the fabricator before you commit.
- Induction-compatible pans. Induction only works with ferromagnetic pans — a magnet should stick firmly to the base. If your pans are aluminium or old stainless without a magnetic base, budget for new pans. This applies to every induction hob, flush or portable.
- Power management limits. A flush hob balances power across zones, but it still has a total ceiling: four large pans at full power isn’t possible, and the hob throttles zones to protect the circuit.
- The circuit, first. Before you even book a showroom visit, find out whether your home has a 32-amp cooker circuit. If it doesn’t, the decision makes itself: built-in is off the table unless you’re paying for a rewire.
- Rental permission. If you rent, any fixed installation — even a drop-in hob, let alone a flush one — needs written landlord consent. A plug-in hob needs none.
The Bottom Line
The hidden cooker is a genuine step forward: a seamless, flat, wipe-clean cooking surface that looks like nothing when it’s off. If you own your home, have a 32A circuit (or are willing to pay for one), and are renovating anyway, a flush induction hob from AEG, Neff, Bosch, Siemens, or Miele is a legitimate upgrade — and the Bora-style integrated extraction version is the ultimate seamless kitchen if the budget stretches.
But for renters and older flats — the people this site exists for — the honest answer is that the hidden hob is the wrong tool for the job. The 32A circuit requirement is a hard wall, not a detail you can work around. The good news is that the experience — flat surface, pan detection, instant heat, easy cleaning — is available for £35–£150 in the form of a plug-in 13A induction hob, with no electrician, no landlord, and no 6mm² cable involved. It won’t be invisible in the worktop. But it will cook, clean, and live exactly like the thing everyone’s oohing at in the showroom — and you can take it with you when you move.
