Boiler Condemned? What to do!

Boiler Condemned? What to do!

Key takeaways

  • A boiler can be 'condemned' if it's deemed Immediately Dangerous (ID) or At Risk (AR) by a qualified engineer.
  • If your boiler is condemned remember to keep calm and logically assess replacement options.
  • If ever in doubt please contact a Gas Safe registered engineer.

If your boiler has been recently condemned, it can be a cause for concern as panic and indecision can begin to cloud your rationality and judgement process.

Don’t worry, here at iHeat we’re experts in all things boilers, and in this blog we’re going to guide you on how to proceed through this process

What Is A ‘Condemned’ Boiler?

The term condemned relates to any boiler that has been deemed not safe for use by a Gas Safe registered engineer.

A boiler may be classified ‘condemned’ in one of the following two ways - 

ID (Immediately Dangerous) 

The most serious type of classification, a boiler with this certification could pose a genuine danger to life and will be immediately disconnected by the engineer assessing the boiler.

If the occupant refuses to have their condemned boiler disconnected, the engineer must report this to the Gas Emergency service Provider (ESP) who actually have the power to enter the property in order to disconnect the boiler and ensure site safety.

At Risk (AR)

A boiler declared to be at risk will have at least one serious problem that could cause potential harm to the owner or property. The boiler will be subsequently disconnected and the owner advised not to re-use until the issues have been addressed.

The owner could possibly be advised that while the boiler may not be dangerous at present, it does not meet industry regulatory standards.

ESP Visit

If the Gas Emergency Service Provider assess the boiler but cannot definitively determine whether or not the boiler is safe in terms of continued use, they may still apply a ‘danger - do not use’ classification

Often costs of a new boiler may be a deterrent for the owners of condemned or faulty boilers to upgrade to a new boiler, however safety should be considered paramount, also new modern boilers are far more efficient than antiquated models and would start to pay for themselves in reduced outgoings!

What To Do If Your Boiler Is Condemned

Keep Calm

It’s understandable that this is a distressing situation, but it’s important to remember the engineer will have already assessed the boiler and taken the appropriate measures to ensure safety, so no need to panic.

Don’t rush or worry, simply read the engineers report and don’t be afraid to ask questions if you still have doubts.

How To Avoid A Condemned Boiler

Arrange A Boiler Service

It can be beneficial to have your boiler serviced by a gas safe registered engineer every 12 months or if you notice a decrease in its performance.

Keep The D.I.Y To A Minimum

While it is often tempting to carry out small repairs on your faltering boiler, it’s always best to leave the work to a professionally trained heating expert, especially for safety purposes.

Get A New Boiler

Even if your old boiler has not been officially classified as ‘condemned’ it may behove you to consider upgrading, proactively replacing ageing or faulty boilers at the earliest signs of degradation, this preventative step is far more prudent than reactive maintenance.
