No Power In The Kitchen

What's happening?
Kitchen power loss is when sockets, the oven, or other kitchen appliances stop working while other rooms may still have power. UK kitchens usually run on more than one circuit: ring or radial sockets share an MCB, lighting has its own breaker, and a freestanding or built-in cooker often sits on a dedicated 32A or 40A circuit. An RCD (residual current device) may protect several of those circuits at once, so one fault under the sink can kill a whole bank of kitchen outlets. Picture a neighbour’s kitchen after a Sunday roast: the hob is dead, the fridge has gone quiet, hall lights still work, and the consumer unit shows one kitchen MCB or the RCD flipped to off. That pattern is kitchen power out on a single circuit or RCD group, not a whole-house blackout.
Book an electrician
What usually causes it?
- An MCB on the kitchen sockets or cooker circuit tripping after overload (kettle, microwave and toaster on one ring at once)
- An RCD tripping from a leaking dishwasher, washing machine, fridge-freezer, or wet socket under the sink
- A faulty appliance with a short to earth that only shows when that plug is in use
- Water ingress from a sink leak, dishwasher hose, or condensation around a cooker connection
- A loose cooker connection at the cooker switch, terminal block, or oven flex
- A damaged socket or spur serving the worktop
- Rarely, a genuine supply issue that also affects other rooms (check neighbours and the rest of the house first)
Is it dangerous?
Losing kitchen power itself is usually inconvenient rather than immediately life-threatening, but the underlying fault can be serious. An RCD that will not stay on often means earth leakage: damp wiring, a cracked appliance cable, or water in a socket. Repeatedly forcing an MCB or RCD back on while the fault is live can overheat connections. Food in a fridge-freezer is at risk after a few hours without power, which is why many homeowners treat a dead kitchen as urgent even when it is not an emergency call-out. Do not poke wet hands into sockets or open the consumer unit cover to “check wires.” If you smell burning, see scorch marks, or the board feels hot, treat it as urgent and call an electrician, or 999 if there is smoke or flame.
Can I fix it myself?
Safe checks only, then stop. With dry hands: 1. Confirm whether only the kitchen is out, or the whole house (and whether neighbours are out too). 2. At the consumer unit, look for a tripped kitchen MCB or an RCD in the off/middle position. 3. Unplug every appliance on the dead kitchen circuit (dishwasher, washing machine, kettle, toaster, microwave, fridge if it shares that circuit). 4. Reset the RCD first if it is off, then the kitchen MCB. 5. Plug appliances back in one at a time. If the trip returns when a specific appliance goes in, leave that appliance unplugged and book an electrician. 6. Do not keep resetting if the breaker trips immediately with everything unplugged: that points to a wiring or socket fault. Do not dismantle the cooker connection, do not tape a breaker in the on position, and do not work inside a wet under-sink cupboard with power still live. Leave diagnosis beyond the unplug-and-reset method to a competent electrician.
When should you call an electrician?
Call an electrician the same day if kitchen power will not stay on after a careful unplug-and-reset, if the trip returns with everything unplugged, or if you smell burning or see scorch marks at a socket or cooker switch. Bring it forward to an emergency call if the consumer unit is hot, buzzing, or smoking, or if water is still present around live sockets. A quiet fridge-freezer after several hours also justifies a same-day booking for many households.

What will the electrician actually do?
- Confirm which kitchen circuits are dead (sockets, lights, cooker 32A/40A) and whether an RCD or MCB is involved
- Isolate safely and test for earth leakage, short circuits, and loose connections at sockets, the cooker switch, and under-sink junctions
- Identify a faulty appliance versus a fixed-wiring fault, and advise repair or safe isolation of that circuit
- Repair or replace damaged sockets, spurs, or cooker terminals as needed
- Check for water ingress and advise drying and making good before restoring power
- Retest the circuit and RCD operation before leaving the kitchen live again
