Gas Supply Pressure Fluctuations caused by ME war

Over the last three weeks (April 2026), my Glow Worm Energy 18r boiler has started showing the F28 ignition fault early in the morning (around 06:00) before the boiler calls for gas to service the central-heating and hot water systems in my home. I reset the boiler and it fires up okay when called upon to do so at 06:30/07:00 but I am now investigating the cause of the fault. One possible cause is fluctuation of gas pressure and I am wondering if the war in the Middle East has caused the pressure of gas supplied to domestic homes in the UK to be temporarily reduced overnight resulting in the F28 fault message? Have other Ovo users experienced this fault condition recently, or has the war caused fluctuations in the pressure of gas supplied to domestic premises?

Howdy ​@BenThePen ,

That… Is rather curious…

Personally - and this really is just me - I can’t think of a reason why such events elsewhere would cause a random pressure drop like that. IIRC gas isn’t transported to the UK from that part of the world via pipelines - it’s transported by ships. And there are multiple sources for redundancy.

My best guess is that something else is going belly up - possibly a bad ignition lead or the gas valve is on the blink.

Definitely one for a Gas Safe Engineer to take a look at. Feel free to pick your own, but https://www.gassaferegister.co.uk/ should make it easy to find one.

    Morning ​@BenThePen and a warm welcome to the OVO Forum. I hope you’re well.

     

    ​@Blastoise186 is right in what he’s saying - world events are unlikely to have a direct effect on the Grid and gas flow into your home. Potential causes of this fault (following a Google search) could be:

     

    • Faulty Ignition Leads/Electrode: Components failing to spark or detect a flame.
    • Gas Valve Malfunction: Valve failing to open to allow gas into the burner.
    • Burner Debris: Carbon buildup in the burner preventing ignition.
    • PCB Failure: The main circuit board not controlling the ignition sequence.

     

    Definitely one to speak to a Gas Safe Engineer about.
