Do Gas Hobs Require FFD or FSD?

When it comes to gas hob safety, you may have come across terms like or . These are vital safety features that prevent gas leaks and protect your home. But are they required on all gas hobs? Let’s take a closer look.

What Are FFD and FSD?

Both FFD (Flame Failure Device) and FSD (Flame Supervision Device) refer to the same thing — a built-in safety mechanism designed to automatically stop the gas supply if the flame goes out unexpectedly.

This can happen due to a draught, spill, or if something boils over. Without an FFD/FSD, unburned gas could escape, posing a serious fire or carbon monoxide risk.

Do All Gas Hobs Need an FFD or FSD?

Yes — in the UK, all new built-in gas hobs must include a Flame Failure Device or Flame Supervision Device to comply with modern safety standards. Since around 2010, this feature has become mandatory for any gas hob sold or installed in the UK.

Older or imported hobs without this protection are not permitted for installation under UK Gas Safety regulations. If your current hob is over a decade old, it may not have this feature — so it’s worth checking before use or replacement.

How to Check if Your Hob Has an FFD/FSD

It’s simple to check whether your hob includes one:

Look closely at the burner — you should see a small metal probe or sensor near the flame ring.
Consult your hob’s manual or look up the model number online.
Most modern gas hobs will clearly state “Flame Failure Safety Device” or “FFD/FSD included” in their specifications.

Why It Matters

Having a Flame Failure Device is not just a legal requirement — it’s an essential safeguard for your home. It protects against gas leaks, reduces fire risks, and ensures your hob meets current safety standards.

If you’re installing or replacing a gas hob, always check it has an FFD/FSD and ensure installation is carried out by a Gas Safe registered engineer.

Conclusion

All modern gas hobs sold in the UK must be fitted with a Flame Failure Device or Flame Supervision Device. These systems are designed to stop gas flow automatically when the flame goes out — keeping you and your kitchen safe.

If you’re buying or installing a new gas hob, make sure this essential safety feature is included to stay compliant and secure.
