Commercial Induction Hob Buying Guide: The Complete UK Guide (2026)
Induction hobs represent the F-Gas-free, net-zero evolution of commercial kitchen cooking. Unlike gas ranges, induction delivers 90% energy efficiency, ferromagnetic pan heating without open flame, and full compliance with UK Building Regulations Part L and BS EN 60335-2-x standards. This guide covers pan compatibility testing, electrical specifications (1.8–3.5 kW zones, single-phase or 3-phase), 12+ multi-brand sourcing from Buffalo/Apuro entry-tier through Bonnet/Riedel premium ranges, UK regulatory frameworks (Building Regs, UKCA, EAW 1989, DW/172 extraction), and total cost of ownership analysis vs gas alternatives.
Key Facts at a Glance
- Ferromagnetic pan compatibility: Induction requires ferromagnetic pans (iron-based). Non-magnetic stainless, aluminium, and copper cookware will not work. Test with a magnet.
- Energy efficiency: 90% energy transfer vs 40–50% for gas. Reduces energy spend per boil-hour by 60–65%.
- Power per zone: 1.8–3.5 kW single zones; multi-zone ranges require 3-phase 16A (total load 14 kW+).
- F-Gas irrelevant: No refrigerant cooling. Induction is future-proof for net-zero carbon targets and EU F-Gas phase-out.
- Price tiers: Entry (Buffalo/Apuro £150–£400), Mid (Lincat/Falcon £500–£1,500), Pro (Riedel/Diamond £2,500–£4,500), Specialist wok-induction (Casta/Adventys £3,500–£8,000).
- Installation: 3-phase 16A supply required for multi-zone. PAT testing and UKCA certification mandatory. DW/172 Type II extraction canopy compatible.
- UK regulatory: Building Regs Part L (energy efficiency), BS EN 60335-2-x (safety), UKCA post-Brexit, EAW 1989 electrical compliance.
- Lifespan: 7–10 years commercial duty; longer than gas (5–7 years). Higher upfront cost offset by energy savings over 5 years (£13,500+).
Commercial induction hobs are now standard across Michelin-starred kitchens, major chains (Wagamama, Pret, Jamie’s Italian), and public sector catering (NHS, schools, universities). This guide provides comprehensive specification guidance for UK trade buyers seeking energy-efficient, F-Gas-free cooking solutions aligned with net-zero targets.
What is Commercial Induction Cooking?
Commercial induction hobs use a high-frequency magnetic field to heat ferromagnetic cookware directly, bypassing the intermediate heating step of gas or electric elements. When a compatible pan sits on an induction surface, the magnetic field induces electrical currents in the pan base, generating heat at 90% efficiency—the highest of any commercial cooking technology. Gas ranges achieve 40–50% efficiency; the remaining energy vents as heat and smoke.
This efficiency translates directly to utility savings. A 2-zone induction hob (7 kW total) boils 20 litres of water in 2–3 minutes, drawing ~0.5 kWh per boil. An equivalent gas range consumes ~1.2 kWh of energy (accounting for vented heat) and takes 4–5 minutes. Over a busy 16-hour service with 40 boil cycles daily, the annual energy cost difference is approximately £3,200–£4,100 per hob in favour of induction.
Pan Compatibility & Ferromagnetic Testing
Induction requires ferromagnetic cookware. Ferromagnetism is the ability of a material to retain a strong permanent magnetic field. In commercial kitchens, this means iron-based stainless steel, cast iron, or carbon steel pans. Non-magnetic stainless (austenitic 300 series), aluminium, copper, and ceramic cookware will not work on induction.
Quick test: Apply a neodymium or ceramic magnet to the pan base. If it sticks firmly, the pan is induction-compatible. If it falls away or clings weakly, it is not compatible.
Most modern commercial cookware (Vollrath, Paderno, Matfer) is induction-compatible by default. However, many kitchens have legacy non-magnetic stainless or aluminium batterie that will require replacement. Budget £40–£80 per pan (saucepan/stockpot) for quality ferromagnetic replacement cookware. A full battery swap for a 4-zone kitchen (20–25 pans) is typically £1,200–£2,000.

Electrical Specifications & Installation Requirements
Single-zone (1.8–2.2 kW): Standard 13A single-phase supply. Existing kitchen wiring in most UK venues.
Dual-zone (3.5–4.2 kW): Can operate on 13A single-phase with reduced simultaneous power on both zones, or 3-phase 16A for full power. Three-phase wiring is preferable for reliability.
Multi-zone (7–14 kW): Requires 3-phase 16A per phase supply. Total demand is distributed across the three phases (Red, Yellow, Blue). A 4-zone 14 kW hob = 4.66 kW per phase, well within the 16A (11 kW per phase) limit for UK small commercial contracts.
Installation checklist:
- Verify 3-phase supply is available. Contact your DNO (Distribution Network Operator) for load assessment if above 10 kW.
- Install a qualified electrician (Part P competent, NICEIC approved). Cost: £400–£800 for 3-phase install.
- PAT (Portable Appliance Testing) certificate required at handover. Cost: £25–£50 per unit.
- UKCA certification label must be visible on the hob. Ensure manufacturer provides UK conformance documentation.
- Ensure extract hood is DW/172 Type II compliant (minimum 400m³/h extraction for 4-zone; scale proportionally for single/dual-zone).
- RCD-protected circuit (Residual Current Device) recommended for induction (electromagnetic EMC sensitivity).
- Bench surface must be fire-resistant (stainless steel or commercial-grade ceramic). Avoid wood or laminate directly under hob.
- Allow 20cm clearance on either side of the hob for thermal dissipation.
Multi-Brand Sourcing Strategy: 12+ Suppliers
The UK commercial induction market fragments into tier-based supplier ecosystems. Buying direct from manufacturers often requires minimum order quantities (MOQ) of 2–5 units; smaller venues typically buy through catering equipment distributors (Nisbets, CaterEquip, Paragon) who warehouse common models and handle PAT/warranty.
Entry Tier (£150–£400 single-zone): Buffalo/Apuro (imported Chinese OEM, widespread in budget catering), Hendi (Dutch, Alibaba-sourced, often £200–£300). These are reliable for proof-of-concept or breakout cooking but lack advanced controls.
Mid-Tier (£500–£1,500 dual/quad-zone): Lincat (UK-based, premium mid-market, used in NHS and school kitchens), Falcon (UK, gas heritage, transitioning to induction), Electrolux Professional (Scandinavian, 3-phase multi-zone), Rational Combitherm (German, integrated steam/induction, £2,000–£3,500). These offer 7–10 year warranties, UK spares support, and advanced programmable controls.
Premium (£2,500–£4,500): Riedel (German, stainless build, 3-phase daisy-chain capable), Diamond (Italian-Belgian, high-spec modular ranges), Moffat (Australian, compact benchtop to 6-zone ranges). Expect stainless enclosures, digital timers, and 10-year expected lifespan.
Specialist Wok-Induction (£800–£8,000): Casta (Italian, 3.5–5 kW wok zones, flat-bottomed wok design), Adventys (French, table-top and drop-in wok induction), Garbin (Italian, modular multi-zone wok systems). These are purpose-built for Asian cuisine and require specific flat-bottomed steel woks (not traditional round-bottomed).
Sourcing recommendation: For budgets under £2,000, source through Nisbets or CaterEquip (Buffalo/Apuro/Hendi models in stock). For mid-range venues (£2,000–£5,000), engage a Lincat or Falcon direct distributor. For high-spec kitchens (£5,000+), obtain quotes from Riedel or Diamond direct via their UK reps, who can customise zone layout and control interfaces.

Installation & UK Compliance Checklist
Contact your DNO (Distribution Network Operator) to confirm 3-phase 16A supply is available. If upgrading from single-phase, expect 4–8 week lead time and £600–£1,500 connection fee.
Hire a qualified electrician to design the circuit, install isolator switches, RCD protection, and earthing. Provide the hob’s kW spec and phase/amp rating to your electrician upfront. Cost: £400–£800 labour.
Ensure the bench is stainless steel or commercial-grade fire-resistant material. Leave 20cm clearance on either side of the hob for air circulation (electromagnetic cooling). Avoid wood, laminate, or untreated surfaces.
Your extract hood must be Type II (recirculating) compliant with Building Regulations Part L. Minimum extraction: 400 m³/h for 2–4 zones. Larger kitchens may require 600–800 m³/h. Verify with your kitchen designer or mechanical engineer.
After installation, your electrician should provide an EICR (Electrical Installation Condition Report) and a PAT test certificate. The hob must display a UKCA conformity mark (post-Brexit UK equivalent to CE). Retain all documentation for insurance and audit trails.
