Are Air Source Heat Pumps Noisy? 7 Proven Facts

cylindrical heat pumps, ashps that comply with MCS 020.

With the rapid rise in air source heat pump installations across the UK and in particular, London, one question continues to surface: are air source heat pumps noisy? While many homeowners worry about disturbing their neighbours or breaching planning conditions, the reality is often misunderstood. Modern heat pumps are designed with noise reduction in mind, […]

How Often Is a Noise Survey Required in the UK?

Noise surveys and noise monitoring are essential for demonstrating compliance with UK noise standards, planning policies, and environmental regulations. How often is a noise survey required for planning applications in the UK? Well… a noise survey typically measures existing sound levels to support a planning or design process. There’s no single rule for how often these assessments must be […]

Acoustical control is about far more than just “making things quieter.” In modern planning and building design, it’s about shaping how sound behaves — both inside buildings and in the wider environment. This is done by different types of acoustic control. From traffic noise spilling into new homes, to plant equipment disturbing nearby residents, to reverberation inside plant […]

How a Noise Impact Assessment Helps New Urban Projects Achieve Planning Success

a city with a tall building, London, UK. Noise impact assessment for City of Westminster and London Borough of Camden. Urban Developments.

Want to know how a noise impact assessment helps new urban developments to achieve planning success? To set the scene, imagine a mixed-use scheme with noise sensitive receptors nearby and within the development itself. The architects need to consider externally located condenser ASHP units and a kitchen extract fan. But… it’s noisy. How can a […]

Noise Assessment Survey: A Complete UK Guide for 2025

TL;DR: If your proposed scheme is noise sensitive (e.g., new homes) or noise generating (e.g., plant, kitchens, delivery yards), you’ll likely need a noise assessment to support planning. A robust report will reference the correct standards (e.g., BS 8233:2024, ProPG, BS 4142, and BS 5228), use representative monitoring (day & night, or alternative periods where relevant), model future conditions, and set […]

Environmental Noise Solutions: How to Get Planning Consent

If you’re trying to get planning consent, designing or building in the UK, noise objections can stall a great scheme. Planners want confidence that residents, neighbours and site users won’t be harmed by sound from roads, rail, plant or construction. The outcome you want is clear: a clean planning consent that’s deliverable without nasty surprises. […]

Heat Pump Noise Complaints: Easy 7-Step Guide to Meet UK Planning Requirements

A Ballu air conditioner condenser unit mounted on a building exterior, showcasing modern HVAC technology. Noisy heat pump. Air source heat pump noise complaints and mitigation.

For UK developers, architects, and planners, one of the most persistent challenges with heat pump adoption is noise. Systems designed for efficiency can attract objections if they disturb neighbours or exceed planning thresholds. The real difficulty lies in predicting acoustic impact, understanding planning requirements, and choosing mitigation before problems arise. Unlike other technical issues, heat pump […]

You can find a copy of this British standard here. In this guide, we […]

Noise Pollution in Residential Areas — BS 8233, BS 4142 and BS 5228 Explained

Noise pollution in residential areas and developments. text over black background representative of BS 8233, BS 4142 and BS 5228 noise assessments.

Noise from road traffic, rail lines, fixed plant, and neighbours is a common hurdle for housing proposals. It can disturb sleep, reduce quality of life, and stall planning applications. Noise pollution in residential areas is one of the most frequent triggers for planning conditions or refusals in the UK. Most developers, planners, and architects want a simple […]

Bass That Travels: How to Manage Room Modes in Studios

a bunch of speakers that are sitting on a table after being destroyed by excessive speaker boundary interference response (SBIR) and room modes.

For music and media producers, the frustration is familiar: a bass line feels perfect in the studio, only to sound thin in a car or overpowering on a client’s laptop. The culprit is often room modes in studios, combined with other low-frequency issues like SBIR (speaker boundary interference response) and poor subwoofer alignment. These distort monitoring […]
