The situation
Landlords who answer their own emergency calls — the ones who have not outsourced the whole thing to a managing agent — know the value of a good van kit. Roughly 40% of the calls you get marked 'emergency' by a tenant are not actually emergencies at all. They are things you can talk the tenant through or fix yourself in 20 minutes, provided you have the right kit with you.
This is the kit I keep in the car boot for my own two rental flats in Kent. Eight items, all available on Amazon, total spend around £130–£230. It pays for itself the first time you avoid a single emergency plumber call-out.
Why this kit matters
Emergency plumbers, electricians and drainage firms charge £90–£180 per call-out in Kent, often with a two-hour minimum. Three avoided call-outs covers this entire kit. And tenants — especially good ones — remember the landlord who turned up in person with the right tools. It is the difference between a one-year let and a five-year let.
It also reduces the chance of a 'patch job by a cowboy' disaster. The worst landlord scenarios I have seen involve a tenant calling whichever 24-hour number came up first on Google, a £400 invoice for a £20 job, and a disputed deduction that ends up at the deposit scheme. Kit in the van means you answer the call yourself.
The kit — every item you need
Universal Stopcock Key (Set of 3 Sizes)
~£8–£15Why it's in the kit: When a pipe bursts at a tenanted property, you need the water off in the street stopcock before you drive. Full stop.
A three-piece set covers every stopcock design you will meet in a UK street — the square key, the T-handle and the long-reach. Keep one in each vehicle and one in a marked box at the rental. Fifteen pounds now, a cancelled insurance claim later.
View on Amazon →Heavy-Duty Plunger + Drain Auger (Plumbing Snake)
~£15–£35Why it's in the kit: A blocked toilet or sink is the single most common 'urgent' tenant call. 90% of the time a plunger and a snake fix it without a plumber.
Get a proper cup-plunger (the bell-shaped one for flat drains) and a 3-metre flexible drain auger — often called a plumbing snake — with a hand crank. Between them they clear hair blockages, kids' toys and the majority of food-waste blockages. For anything else see our drain unblocker picks.
View on Amazon →Chemical Drain Unblocker (Caustic, 5-Litre)
~£15–£25Why it's in the kit: For grease and soap-build-up blockages where the snake cannot reach — usually the kitchen sink and shower waste.
A 5-litre bottle of trade-grade caustic drain unblocker (Mr Muscle Professional, HG, or a builder's merchant own-brand) clears most grease and soap blockages inside an hour. Always follow the instructions, wear gloves and goggles, and ventilate — this stuff is genuinely nasty. For sewage blockages beyond the trap, call a drainage specialist; chemicals will not help.
View on Amazon →RCD Plug-In Adapter (13A, BS 7071)
~£12–£25Why it's in the kit: For testing whether a dead socket is a tripped RCD or a real electrical fault before you call an electrician.
A plug-in RCD adapter lets you plug any appliance into any socket through a known-good 30mA protection device. If the RCD adapter trips, it is the appliance. If it does not trip but the circuit still fails, it is a fixed-wiring problem for an electrician. Saves countless £90 emergency call-outs for what turns out to be a faulty kettle.
View on Amazon →10-Year Sealed-Battery Smoke Alarm (BS 5446)
~£15–£25Why it's in the kit: Legally required — one per floor in every tenanted property. Keep spares for when one expires or a tenant pulls one off the ceiling.
Must be BS 5446-compliant (or EN 14604 for the same standard). The sealed 10-year battery type means no tenants 'borrowing' the 9V battery for a remote control. Kidde, FireAngel and Aico are the three brands you want. Install and date them; replace the whole unit at year ten. See our full smoke alarm guide.
View on Amazon →Carbon Monoxide Alarm (BS EN 50291, 10-Year)
~£18–£30Why it's in the kit: Legally required in any room with a fixed combustion appliance — gas boiler, wood burner, open fire. Non-negotiable for rentals.
BS EN 50291-rated with a 10-year sealed battery and an LCD display showing current PPM. FireAngel CO-9X-10 and Kidde 10LLCO are the two you will see in most landlord kits. Mount at head height near the appliance, not on the ceiling — CO is roughly the same density as air, not lighter.
View on Amazon →Basic Landlord Toolkit (26–40 Piece Boxed Set)
~£30–£60Why it's in the kit: For the boring everyday jobs between tenancies — tightening handles, re-securing curtain poles, changing washers, swapping lightbulbs.
A boxed 26–40 piece set with screwdrivers, spanners, pliers, a hammer, a tape measure and a utility knife. Stanley, Draper or Rolson all do decent entry-level sets for £30–£50. Spend another £30 on a second-hand cordless drill and you have everything you need to sort 80% of between-tenancy snags without calling anyone.
View on Amazon →Compact LED Torch (USB Rechargeable, 500+ Lumens)
~£15–£25Why it's in the kit: For reading meters in dark cupboards, checking stopcocks under sinks, and every late-night call-out where the tenant says 'the lights won't come back on'.
A pocket-sized USB-rechargeable torch lives in the glove box. 500+ lumens is enough to light a whole kitchen when the power is off; a zoom focus lets you read serial numbers on boilers from six feet away. Nitecore, Fenix and Olight all make good ones for under £30.

FAQs
Am I legally required to provide any of this to tenants?
Yes — the smoke alarm on each floor and the carbon monoxide alarm in any room with a fixed combustion appliance are both legal requirements under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 for England. Scotland and Wales have similar but slightly different rules. The rest of this kit is for you as landlord, not for the tenant — though leaving a spare set of smoke alarm batteries and a stopcock key at the property saves 11pm phone calls.
What's the single best item on this list for reducing call-outs?
The RCD plug-in adapter. Nine out of ten 'the lights are off' tenant calls turn out to be an RCD tripped by a faulty appliance. Teaching a tenant how to identify which appliance is the culprit (which this adapter does in 30 seconds) prevents you paying £90 emergency electrician fees for a problem a tenant could have solved.
How quickly do I need to respond to emergencies?
Legally, you must respond to genuine emergencies (no heating, no water, serious damp, no working toilet) within a reasonable time — case law suggests 24 hours for heating in winter, 48 hours for most else. Having this kit means you can often talk a tenant through a fix on the phone or attend in person without waiting for a tradesperson's next-day slot.
When do I actually need to call a Gas Safe engineer?
Any time a tenant reports: a gas smell, a boiler not firing, a pilot light that will not stay lit, yellow or lazy flames on a hob, or a CO alarm going off. Do not attempt any of these yourself — it is illegal for a non-Gas Safe registered person to work on gas appliances, and it is genuinely dangerous. See our Gas Safe engineer listings for Kent below.
