Is the grass really greener? New research reveals how much better (or worse) off you could be in another country

As across the UK temperatures officially hit single digits, homes will be turning to their trusty thermostats to give them some much-needed warmth this autumn. However, with your boiler sitting docile all summer, you may find yourself without heat when you need it. With an average of 5,100 searches each month, in autumn, searches for “boiler repair” begin to creep up. They peak in December as households find broken boilers when they need it the most. Searches have climbed 257% this month alone. With this in mind, Yell has partnered with David Doran, a plumbing expert at Blackstone Plumbing & Heating Ltd to find out what heating checks you need to make and how to avoid a winter breakdown. What checks should you carry out before turning your heating on? ● Check your boiler pressure Your boiler pressure gives you an idea of how efficiently your heating system is running by telling you the pressure of the water circulating through your system. If the pressure is too high, then this could cause leaks to develop. If it’s too low, the system won’t work as well, leading to ineffective heating, and you’ll find your home will be colder than expected. David explains, “Low pressure can result in ineffective heating, while high pressure can potentially damage your system.” He recommends keeping the pressure gauge between 1 and 2 bars, which provides the ideal balance for optimal performance. If you notice a slight increase in boiler pressure while it’s running, don’t worry—this is completely normal. Just ensure the pressure stays below the 3-bar mark during use. ● Check your thermostat Make sure your thermostat is working properly and accurately reading the temperature. If the readings are inaccurate, the thermostat might cause your boiler to work overtime, wasting energy trying to reach a room temperature that’s already been achieved. Conversely, it could shut the boiler off too early, known as short cycling, leaving you in the cold. David suggests, “ Consider replacing old thermostats with programmable or smart thermostats to improve efficiency. If your thermostat runs on batteries, check if they need replacing. ” ● Test out your heating system before you need it It’s important to test your boiler before you need it, to avoid being one of the thousands of Brits searching for “boiler repair” in December. Run your heating system for a short period (e.g., 15-30 minutes) to ensure all radiators heat up evenly and there are no unusual noises from the boiler or pipes (e.g., banging, clanging, or gurgling sounds). Should you notice anything untoward, such as cold spots, it’s worth reaching out to your local heating specialist . On Yell, you can either browse nearby listings or post an enquiry . ● Ensure your boiler is regularly serviced Annual servicing of your boiler is important to ensure that your system is operating safely. According to insights from HomeServe , more than half (58%) of UK households haven't checked that their boiler is working as it should and 56% of the population haven't had an annual boiler service. David says that it’s important to “ have your boiler serviced once a year. Faulty boilers can lead to dangerous situations like gas leaks or carbon monoxide poisoning, which can be deadly. ” A service includes checks for leaks, blockages, and the correct operation of safety devices. David adds, “R egular servicing keeps your boiler running efficiently. Over time, boilers can accumulate dirt, dust, and limescale, reducing efficiency. A well-maintained boiler burns fuel more effectively, helping you save on energy bills. ” Alongside this, it’s important to remember that many boiler manufacturers require annual servicing as part of their warranty terms. Skipping a service could void your warranty, leaving you without coverage if something goes wrong. Additionally, some home insurance policies may also stipulate that your boiler must be serviced regularly. A local plumber should be able to service your boiler and give you the advice and support you need. Tips on how to get the most out of your heating during cold weather According to Pepper Money’s Specialist Lending Study , 73% of people say that even a £100 increase in monthly bills would seriously affect their household finances. With winter on the way, maximising the efficiency of your heating during cold weather can keep your home warm and comfortable while also saving on energy bills. David Doran and Yell provide tips on how to make the most of your heating in the cold weather: ● Only set your heating to when you need it: A programmable thermostat allows you to create a heating schedule that fits your routine, reducing wasted energy when you’re not home or during sleeping hours. Smart thermostats can learn your habits and adjust heating automatically, optimising efficiency. ● Aim for a comfortable temperature: Aim for a comfortable temperature between 18-21°C (64-70°F). Setting your thermostat at 18-20°C can significantly reduce energy consumption compared to higher temperatures. For every degree you lower your thermostat, you can save around 1-3% on your heating bill. ● Only heat the rooms you need: Thermostatic radiator valves (TRVs) only heat the rooms you’re using. Keep unused rooms at a lower temperature or turn the radiators off entirely in those spaces. ● Don’t block the heat with furniture: Avoid placing large furniture or curtains in front of radiators. This blocks heat circulation and makes your heating work harder to warm the room. Clear airflow helps the heat distribute more effectively throughout your home.
