When It\u2019s Harmless and When It\u2019s Not"},"content":{"rendered":"<body>\n<p class=\"wp-block-paragraph\">You flick the heating on, and ten minutes later there\u2019s a smell. Not a nice one. Maybe it\u2019s warm and dusty, maybe it\u2019s sharp, maybe you just can\u2019t put a name to it. So you\u2019re stood in the hallway, sniffing the air, wondering whether to ring someone or carry on with your evening.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here\u2019s the short version, in case you\u2019re in a hurry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The short answer:<\/strong> a mild, dusty smell during the first heating session after summer is common and usually harmless. A smell of gas, burning plastic or hot metal is not. If you smell gas, get outside and call the National Gas Emergency Service on <strong>0800 111 999<\/strong>. It\u2019s free and answered 24 hours a day. And one more thing worth knowing: carbon monoxide has no smell at all, so a boiler that smells fine isn\u2019t automatically a safe one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We\u2019re Boiler Services London, a team of Gas Safe registered engineers with 8 years of looking after boilers across Greater London. What follows is how we\u2019d talk you through it if we were standing in your kitchen, starting with the one thing that can\u2019t wait.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">If it smells like gas, stop reading and move<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Natural gas has no scent of its own. Suppliers add one so leaks are easy to notice, and people most often describe it as rotten eggs or sulphur. If that\u2019s what you can smell:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>No flames and no switches.<\/strong> Don\u2019t smoke, light anything, or turn lights and appliances on or off.<\/li>\n\n\n\n<li><strong>Open doors and windows<\/strong> to let the gas clear.<\/li>\n\n\n\n<li><strong>Turn the gas off<\/strong> at the meter control handle, unless your meter is in a cellar.<\/li>\n\n\n\n<li><strong>Get outside<\/strong> and call <strong>0800 111 999<\/strong> from there, or from a neighbour\u2019s phone.<\/li>\n\n\n\n<li><strong>Stay out<\/strong> until you\u2019re told it\u2019s safe to go back in.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If anyone feels dizzy or sick, or has collapsed, call 999.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can\u2019t fix a gas leak yourself, and you shouldn\u2019t try. Gas work has to be done by a Gas Safe registered engineer, and the emergency service will tell you who to involve once the property is safe.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Smell by smell: what your nose is telling you<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not every odour means the same thing. This is the quick reference we\u2019d pin on the fridge.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>What you smell<\/th><th>Likely cause<\/th><th>How worried to be<\/th><th>What to do<\/th><\/tr><tr><td>Rotten eggs or sulphur<\/td><td>Gas escaping<\/td><td>Very.

Fire it up and that dust burns off, which can smell like burning fabric or a hot electric heater. To some noses it even smells faintly like gas, which is why people panic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s probably dust if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It shows up the first time or two you use the heating after a long break.<\/li>\n\n\n\n<li>It\u2019s mild, not sharp or chemical.<\/li>\n\n\n\n<li>It fades quickly and stays gone once the boiler has been running.<\/li>\n\n\n\n<li>The boiler otherwise behaves normally, with no error codes, strange noises or pressure drops.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If it lingers, or comes back every time the boiler fires, it isn\u2019t dust any more. And if you honestly can\u2019t tell whether it\u2019s dust or gas, treat it as gas. A wasted phone call costs you nothing. The other mistake can cost a great deal more.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A practical tip: switch the heating on for a short test on a mild day in September or October. That way, if something does smell off, you\u2019re finding out on a Tuesday afternoon rather than during a January cold snap.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The one you can\u2019t smell: carbon monoxide<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Carbon monoxide (CO) is the reason we never tell anyone to judge a boiler by its smell alone. The Health and Safety Executive describes it as a colourless, odourless, tasteless gas, made when fuel doesn\u2019t burn properly. According to HSE statistics, around 7 people a year die in the UK from CO poisoning caused by gas appliances and flues that haven\u2019t been properly installed, maintained or ventilated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seven is a small number, and that\u2019s the point. These are exactly the cases that a yearly service and a cheap alarm exist to prevent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Signs your boiler may not be burning properly<\/strong> (these come from HSE):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Flames that are yellow or orange instead of crisp blue<\/li>\n\n\n\n<li>Soot or yellow-brown staining on or around the appliance<\/li>\n\n\n\n<li>A pilot light that keeps blowing out<\/li>\n\n\n\n<li>More condensation than usual on the inside of your windows<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Symptoms to take seriously:<\/strong> headaches, dizziness, nausea, tiredness, breathlessness, and pains in the chest or stomach. They can feel like flu or a stomach bug, which is why CO gets missed. The NHS points out that symptoms can come and go, get worse in the affected room and ease when you leave it or go outside.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>If you suspect carbon monoxide:<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Get into fresh air and leave doors and windows open as you go.<\/li>\n\n\n\n<li>Switch the appliance off and shut off the gas at the meter if it\u2019s safe to do so.<\/li>\n\n\n\n<li>Call the National Gas Emergency Service on <strong>0800 111 999<\/strong>.<\/li>\n\n\n\n<li>Call <strong>NHS 111<\/strong> if you think you have symptoms. Call <strong>999<\/strong> or go to A&amp;E if anyone is struggling to breathe or has suddenly become confused.<\/li>\n\n\n\n<li>Don\u2019t go back in until you\u2019ve been given the all-clear.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Every home with a gas boiler should have a working CO alarm. Think of it as a smoke alarm\u2019s quieter cousin.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Smells that aren\u2019t gas: here\u2019s what we\u2019d do<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">So it isn\u2019t gas, but something still doesn\u2019t smell right. Here\u2019s the calm, sensible order of play.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Switch the boiler off<\/strong> at the boiler itself, and leave it off.<\/li>\n\n\n\n<li><strong>Open a window<\/strong> and give the room some fresh air.<\/li>\n\n\n\n<li><strong>Make a quick note<\/strong> of what the smell is like, where it\u2019s strongest, when it started and whether it\u2019s constant or only when the boiler fires.<\/li>\n\n\n\n<li><strong>Check the display.<\/strong> If there\u2019s an error code, write it down. Our guide on <a href=\"https:\/\/www.boilerserviceslondon.co.uk\/blog\/what-your-boiler-error-code-is-really-telling-you\/\" target=\"_blank\" rel=\"noopener\">what your boiler error code is really telling you<\/a> will help you make sense of it.<\/li>\n\n\n\n<li><strong>Leave the casing alone.<\/strong> Opening up a gas boiler is a job for a Gas Safe registered engineer, not a screwdriver and YouTube.<\/li>\n\n\n\n<li><strong>Call a Gas Safe engineer<\/strong> and give them your notes. They\u2019ll work faster and diagnose better with them.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Before anyone touches your boiler, ask to see their Gas Safe ID card, and check it against the Gas Safe Register. It takes a minute and it\u2019s worth it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re in London and the heating has gone cold at the same time, we handle <a target=\"_blank\" rel=\"noopener\" href=\"https:\/\/www.boilerserviceslondon.co.uk\/boiler-repair-in-london.php\">emergency boiler repair in London<\/a> across the capital, including Worcester and Vaillant models.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Smells rarely turn up on their own<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A boiler that\u2019s unwell usually tells you in more than one way.

One clue is a hint. Three is usually a diagnosis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">An older boiler that keeps smelling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes a smell is the first sign that something inside is wearing out. If your boiler is getting on and the faults keep coming, ask your engineer for a straight answer on whether another repair is sensible or whether replacement is the safer and cheaper route over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you do start thinking about a new one, the worry we hear most is about the rest of the system.

A mild, brief smell is common. If it\u2019s strong, smells of gas, lasts beyond the first session or two, or returns every time, get it checked by a Gas Safe engineer.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794552351856\"><strong class=\"schema-faq-question\">What does a gas leak smell like?<\/strong> <p class=\"schema-faq-answer\">Most people describe it as rotten eggs or sulphur. That smell is added to natural gas so leaks are easy to spot. If you notice it, open windows, turn the gas off at the meter if it\u2019s safe, leave the property and call 0800 111 999 from outside.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794552367361\"><strong class=\"schema-faq-question\">Is a burning smell from a boiler dangerous?<\/strong> <p class=\"schema-faq-answer\">It can be. A faint dusty smell on first use is usually harmless. Burning plastic, hot metal or burning oil can point to an electrical fault or overheating, so switch the boiler off and call a Gas Safe registered engineer.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794552389227\"><strong class=\"schema-faq-question\">Can a boiler leak carbon monoxide without any smell?<\/strong> <p class=\"schema-faq-answer\">Yes. Carbon monoxide is colourless, odourless and tasteless. Warning signs include yellow or orange flames, soot or brown staining, a pilot light that keeps going out, extra condensation on windows, and headaches or dizziness that ease when you leave the house.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794552401090\"><strong class=\"schema-faq-question\">Should I turn my boiler off if it smells?<\/strong> <p class=\"schema-faq-answer\">If the smell isn\u2019t gas, yes: switch it off, open a window and call a Gas Safe engineer. If it is gas, don\u2019t touch switches. Open windows, turn the gas off at the meter if you can, leave, and call 0800 111 999.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794552422645\"><strong class=\"schema-faq-question\">Who do I call about a boiler smell in London?<\/strong> <p class=\"schema-faq-answer\">For gas or suspected carbon monoxide, call 0800 111 999 straight away. For any other boiler smell, call a Gas Safe registered engineer.
