Confirm what you are seeing
Since cockroaches stay hidden by day, it's the evidence that shows up first, droppings resembling ground pepper, shed skins, a musty smell, true near Brixton too, where dense Victorian terraces and converted flats around the market and the town centre. After dark, when they're most active, run a torch behind the cooker, under the sink, and into cupboard corners and door hinges, true near Kennington too, where georgian and Victorian terraces close to the park.
In your own kitchen

Work through the warm, enclosed spots one by one: the plinth beneath fitted units, round the boiler, and any gap where pipework passes through a party wall. None of this reflects on how the flat is kept; a slow leak under the sink can matter as much as anything else.
Ex-GLC blocks and converted warehouse flats

Warm shared pipework running through the ex-GLC blocks near Stockwell and the converted warehouse flats around Vauxhall gives cockroaches a route between units, so a problem on one floor may well have started on another.
If you run a food business
Any food business is legally required, under food hygiene law, to keep proper procedures for pest control running - the same pattern holds near Clapham, where large period houses and mansion blocks around Clapham Common. Keep a record of what's seen, keep stock off the floor, and check boxes as they arrive, true near Stockwell too, where ex-GLC estates and Victorian terraces close to the Underground and bus garage. Let us know the type and size of the premises when you get in touch, commercial work is quoted per site, much as it does near Streatham, where a mix of Victorian terraces and postwar blocks along the high road towards Streatham.
What to avoid while you wait
- Spraying at cockroaches you can see, which scatters the rest into walls and next door
- Moving boxes, appliances or furniture from an affected kitchen into clean rooms
- Leaving pet food, dirty dishes or standing water out overnight
- Bringing in second-hand appliances without checking them first
