Your Tenant Just Texted “The Boiler's Dead” — Now What?

23 September 2026 · 6 min read

It usually arrives at the worst possible moment. You're on the school run, in a meeting, or halfway through dinner, and your phone lights up: "Boiler's dead. No heating, no hot water."

If you self-manage a handful of properties, you'll get this message sooner or later. The good news is that a dead boiler is one of the most predictable repairs you'll deal with. Have a simple playbook ready and you can turn a stressful text into a well-handled job — and a record you'll be glad of later.

1. Acknowledge fast, even before you have answers

The first thing your tenant wants is to know someone has heard them. You don't need a fix yet; you need a reply.

Something like this works well:

"Thanks for letting me know — sorry you're without heating. I'm on it. Can you answer a few quick questions so I can get the right person out?"

A quick acknowledgement lowers the temperature (so to speak), reduces follow-up messages, and shows you're taking your repairing obligations seriously. Aim to reply within the hour where you reasonably can.

2. Triage: what's actually going on?

"The boiler's dead" can mean many things. A few questions help you work out whether it's a two-minute fix or a job for an engineer:

  • Is there any heating or hot water at all? Or just one of the two?
  • What does the boiler display show? Ask for a photo of any error code or the pressure gauge.
  • Is the pressure low? Many combi boilers stop working if pressure drops below about 1 bar.
  • Has the power tripped, or is the thermostat or timer set correctly?
  • Is there a prepayment meter, and does it have credit?
  • Any smell of gas, unusual noises, or signs of leaking water?

Ask for photos or a short video. It saves back-and-forth and gives the engineer useful information before they arrive.

Some issues — a tripped switch, a timer change after the clocks went back, low pressure the tenant is comfortable topping up following the manufacturer's instructions — can sometimes be resolved quickly. Only suggest simple, safe checks. Never ask a tenant to open up the boiler or attempt anything beyond the user controls.

3. Safety first — always

If your tenant mentions a smell of gas, the triage stops there. They should:

  • Call the National Gas Emergency Service on 0800 111 999 straight away
  • Turn off the gas at the meter if it's safe to do so
  • Open doors and windows, and avoid using electrical switches or naked flames

Likewise, if they notice signs of carbon monoxide — headaches, dizziness, a boiler flame that's yellow or orange rather than blue, sooty marks — they should get fresh air, turn the appliance off if safe, and seek advice immediately.

Make sure your tenants know these steps before anything goes wrong. It's worth including them in your move-in information.

4. When to call a Gas Safe engineer

If the simple checks don't solve it, it's time for a professional. For any work on a gas boiler, the engineer must be Gas Safe registered. You can check an engineer's registration on the Gas Safe Register website, and it's sensible to ask to see their ID card when they arrive.

When you book, pass on everything you've collected:

  • The boiler make and model (often on a sticker on the front or underneath)
  • Photos of any error codes and the pressure gauge
  • The tenant's description of what happened and when
  • Access details and the tenant's availability

Loss of heating and hot water — especially in winter, or where tenants include young children, older people or anyone vulnerable — should be treated as urgent. If the repair will take a while, consider whether temporary heaters are appropriate while you wait for parts.

5. Keep the tenant in the loop

Silence breeds anxiety. Once you've booked someone, tell the tenant:

  • Who's coming and roughly when
  • Whether they need to be home or can provide access another way
  • What happens next if parts need ordering

A short update each time something changes goes a long way. Tenants are usually understanding about delays — what frustrates them is not knowing.

6. Document everything as you go

This is the step most DIY landlords skip, and it's the one that matters most later. For every boiler issue, try to keep a record of:

  • When the tenant reported it, and how
  • When you responded, and what you said
  • Photos and videos the tenant sent
  • Who you booked, when they attended, and what they found
  • Invoices and job sheets for the work
  • When the issue was resolved, and confirmation from the tenant

Why bother? Because if there's ever a dispute — about response times, damage, deposit deductions or disrepair — a clear timeline is far more persuasive than trying to piece things together from memory. It also helps you spot patterns: if the same boiler fails three winters in a row, that's a conversation about replacement, not another repair.

7. Tie it back to your gas safety record

While the engineer is there, it's a good moment to check where you are with your annual Gas Safety Certificate (CP12). Make sure the current certificate is filed somewhere you can find it, the expiry date is noted, and a copy has been given to your tenant as required.

If the boiler has been replaced or significantly worked on, keep that paperwork alongside your gas safety records too.

The real problem isn't the boiler

Boilers break. That part's unavoidable. What turns a routine repair into chaos is the admin around it: messages scattered across WhatsApp, texts and email; photos buried in a camera roll; invoices in a drawer; no clear record of who said what and when.

A structured maintenance inbox can help here. Instead of piecing things together from a dozen chat threads, each request has its own record — the tenant's report, the photos, your updates, and the outcome — all in one place. Pair that with a simple home for your compliance documents and expiry dates, and the next "boiler's dead" text becomes a routine job rather than a scramble.

Quick checklist

  • Reply to the tenant quickly, even if you don't have answers yet
  • Ask for photos, error codes and pressure readings
  • Stop immediately and direct them to 0800 111 999 if they smell gas
  • Book a Gas Safe registered engineer for anything beyond simple checks
  • Keep the tenant updated at each step
  • Log the timeline, photos, invoices and resolution
  • Check your CP12 is current and filed

Less chaos. More control.
