Emergency Boiler Repair in London: What to Do When You Lose Heating

The heating’s off, the radiators are cold, and your boiler has stopped working — again. Whether you're managing a residential flat, commercial premises, or your own home, a boiler breakdown can be more than an inconvenience. It can pose a risk to health, safety, and daily operations.

At Pleasant Plumbers, we handle emergency boiler repairs across London every day. Here's what you need to do immediately when your boiler fails — and how to prevent it happening again.

Step 1: Check the Basics Before You Panic

Before calling for an emergency boiler repair in London, check these simple things first:

  • Power Supply: Make sure your boiler is plugged in and switched on.
  • Boiler Pressure: Most boilers operate between 1–1.5 bar. If it's too low, top it up using the filling loop.
  • Thermostat Settings: Ensure the room thermostat isn’t set too low.
  • Gas Supply: Check if other gas appliances (like your hob) are working. If not, call your supplier.
  • Reset Button: Try resetting the boiler once — not repeatedly.

If none of these solve the problem, or if you see a fault code, it’s time to call a Gas Safe registered boiler repair engineer.

Step 2: Know When It’s an Emergency

You need emergency boiler repair services in London if:

  • You have no heating or hot water in cold weather.
  • There’s a leak coming from the boiler or pipework.
  • You can smell gas or burning near the boiler (turn off gas and call 0800 111 999 immediately).
  • The boiler is making loud banging noises.
  • You have vulnerable residents, like children, the elderly, or tenants relying on heat.

If in doubt, it’s always safer to call and have the issue assessed professionally.

Step 4: Don’t Ignore Boiler Warning Signs

Most boiler failures don’t come out of nowhere. Common red flags include:

  • Unusual noises (gurgling, banging)
  • Water pressure dropping
  • Cold spots in radiators
  • Boiler constantly turning off
  • Persistent error codes
  • Leaking pipework or dripping from underneath

Spotting these early and booking a preventative boiler repair could save you from a full breakdown — and emergency call-out charges.
