Super. Simple. Boilers.
No Power In Your Boiler?
Having no power to your boiler can be frustrating and stressful, especially when it means losing access to hot water and central heating. However, before you call an engineer you can try to get your boiler up and running again yourself. Some problems can easily be fixed yourself such as a tripped fuse or an electricity supply issue.
However, other issues may be dangerous to fix yourself and may require you to contact an engineer.
Warmable’s team will put you in contact with a local engineer who can provide you with a free quote. No matter what issues you are having with your boiler, our team can find you the best deals from trusted experts.
What to Check Before Calling an Engineer if You Have No Power in Your Boiler
Tripped Fuse in the Fuse Box
One of the common reasons for no power to your boiler is a tripped fuse in the fuse box (RCB). If another electrical component connected to the same zone as your boiler experiences an issue such as a blown light bulb, it can cause the fuse to trip and disrupt the power supply to your boiler.
To fix this, head to your fuse box and ensure that all the switches are in the correct position. If you find a tripped switch facing downwards, simply flick it back up to restore power to your boiler.
Blown Fuse
Boilers, like all electrical devices, are equipped with fuses to safeguard against power surges. If the fuse blows, your boiler cannot receive power and therefore will not turn on.
Locate the switch controlling power to your boiler (usually located near the boiler or in your airing cupboard), and carefully open the fuse holder with a screwdriver (avoid using a metal object). Replace the blown fuse with a new one to restore power to your boiler.
Electricity Supply Issue
If your central heating boiler lacks power, the problem may lie with your electricity supply. Check your other electrical appliances to see if they are working. If none of them seem to function, you may need to contact your electricity distribution company.
If you have a pay-as-you-go electric metre, ensure you have credit remaining. If you have credit and other appliances still don’t work, there might be a fault with your electric metre. Contact your utility company to resolve the issue over the phone or request a technician to inspect and fix the problem.
Reset Your Boiler
After successfully resolving your boiler’s power issue using the above checks and fixes, remember to reset your system. Most modern boilers have a reset button on the display panel, which you can usually press for a few seconds to restart the boiler. If you can’t locate the reset button, refer to your user manual or check the manufacturer’s website for guidance.
Should You Replace Your Boiler If It Has No Power?
If your boiler frequently experiences issues or is over 10 years old, it may be time to consider a replacement to avoid costly boiler repairs. The market offers a range of options from different manufacturers, many of which come with long warranties.
To find the best deal, consider obtaining fixed-price quotes from various companies. You can complete an online form to receive free quotes from trusted locally-based engineers. You may also be eligible for a boiler upgrade.
Can Weather Lead to No Power in My Boiler?
Yes, severe weather conditions like storms, heavy snowfall, or high winds can cause power supply disruptions in your area. Falling trees, damaged power lines, or transformer failures due to weather-related incidents can all affect your boiler’s power.

When to Call an Engineer If You Have No Power in Your Boiler
While the above checks are safe to perform on your own, certain boiler issues demand the expertise of a Gas Safe registered engineer. Attempting to fix these issues yourself can be dangerous and may cause further damage.
Printed Circuit Board (PCB) Failure
The printed circuit board (PCB) is a critical component that allows various electrical parts of your boiler to communicate with each other. If the PCB develops a fault, your boiler might display an error code or refuse to turn on.
PCB failure can either be a straightforward fix or require a replacement, which can cost up to £500. If your boiler is old or out of warranty, you might consider investing in a new one.
Power Light Failure
A less severe issue that can mimic a power loss is a power light failure. This problem often results from a faulty LED light or a broken power light, giving the illusion that your boiler has no power.
However, your boiler should still function as normal despite this issue. To identify and fix the problem, it’s best to have a registered engineer carry out tests.
Blown Internal Fuse
Boilers have internal fuses that can blow due to age or other factors. Checking and replacing internal fuses is a task best left to your heating engineer, as it involves handling electrical components.
Once the engineer replaces any blown internal fuses, they will test your boiler to ensure they don’t blow again. If the problem persists, it could indicate another fault with your boiler, which the engineer will investigate and fix.
What Should I Do if My Smart Home System Has No Power and My Boiler Is Connected?
If your boiler is part of a smart home system and you have lost control due to a power issue, check if your smart hub or controller is also without power. If the hub is functioning correctly and connected to the internet, try restarting it. If the issue continues, consult your smart home system’s manufacturer or a technician familiar with the system for further troubleshooting.
Are Power-Related Boiler Issues Covered by My Warranty?
Not usually, no. Typically, warranties cover defects in materials and workmanship, but they might not cover issues caused by external factors, such as power supply problems.
The coverage of power-related boiler issues under your warranty depends on the specific terms and conditions of the warranty provided by the manufacturer or installer. Review the warranty documentation or contact the manufacturer/installer to determine the extent of coverage.
You could also consider solutions depending on your type of boiler.
Can I Still Use My Gas Hob or Cooker if the Boiler Has No Power?
Yes, sometimes. If the gas supply to your home is unaffected, you can still use your gas hob or cooker even if the boiler has no power. These appliances do not rely on the boiler’s electricity to function, so they should work.
