In this post, we\u2019ll explain how loud they actually are, what the rules are in the UK, and what really makes the difference when it comes to noise.<\/p>\n\n\n\n<div style=\"height:57px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">How loud is a heat pump?<\/h2>\n\n\n\n<p>Most modern air source heat pumps produce around&nbsp;<strong>40\u201350 decibels (dB)<\/strong>&nbsp;during normal operation. Even when working harder, such as during very cold weather or a defrost cycle, they typically peak at&nbsp;<strong>55\u201360 dB<\/strong>.<\/p>\n\n\n\n<p>To put that into context:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>30 dB \u2013 a quiet library<\/li>\n\n\n\n<li>40 dB \u2013 a quiet room or fridge humming<\/li>\n\n\n\n<li>50 dB \u2013 light rainfall<\/li>\n\n\n\n<li>60 dB \u2013 normal conversation<\/li>\n\n\n\n<li>70 dB \u2013 vacuum cleaner<\/li>\n<\/ul>\n\n\n\n<p>In real terms, a properly installed heat pump is usually closer to&nbsp;<strong>background noise<\/strong>&nbsp;than anything intrusive.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">UK noise regulations explained<\/h2>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>In the UK, heat pumps are covered by strict planning and noise rules.<\/p>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Most domestic installations fall under&nbsp;<strong>Permitted Development<\/strong>, but they must comply with&nbsp;<strong>MCS 020<\/strong>&nbsp;noise standards. The key requirement is that the heat pump must not exceed&nbsp;<strong>42 dB at the nearest neighbour\u2019s boundary<\/strong>.<\/p>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>This limit is assessed at the&nbsp;<strong>quietest time of night<\/strong>, when background noise levels are lowest. If a heat pump meets this requirement at night, it will be even less noticeable during the day.<\/p>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>These rules exist specifically to protect neighbours and ensure heat pumps don\u2019t become a nuisance.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Why do some people think heat pumps are noisy?<\/h2>\n\n\n\n<div style=\"height:13px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>When noise complaints do happen, it\u2019s rarely because of the heat pump itself.
