Why is my boiler not working after I got a smart meter installed?

Hi everyone

Which number can i contact if the boiler is failing? There doesnt seem to be a helpline for this emergency. The emergency line only deals with gas leaks etc . Boiler failure is a serious emergency in the chilling cold temperatures as there doesnt seem to be hot water any either PLEASE HELP US!!!!

I presume you mean the OVO boiler cover? If so the only number I can find is 24 hour emergency helpline 0330 102 8905 which is at the end of their terms and conditions brochure

Yep BPLightlog is spot on @Sop2328 , 0330 102 8905 is the 24/7 OVO Homeplan boiler cover emergency helpline. See the terms and conditions in this PDF file for more info on OVO Homeplan.

Did you get this sorted? 

Hi, we got it all sorted but not with OVO, as i mentioned we dont have boiler cover with OVO, the question was how could they help if we don't have the plan, i was told to just call a local engineer as gas supplier dont help you if you dont have a plan with them

BPLightlog, you misunderstood my question, we do not have the boiler plan....you havent answered my question

If you have no cover in place then you will need to call a local engineer to come take a look at your boiler. You can search for one here: https://www.gassaferegister.co.uk/boiler-engineer/

Thank you Paul for answering my question properly. I have done just that and the service and efficiency of the company we called was fantastic

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.
