RESIDENTIAL
Air Source Heat Pump (ASHP) Noise Surveys and Assessments
(MCS 020 and BS4142)
MCS 020 Desktop Noise Assessment (Permitted Development)
For many domestic ASHP installations, compliance with MCS 020 is required to meet permitted development criteria. This standard sets noise limits at the nearest neighbouring property and is typically assessed using a desktop calculation and noise modelling approach, avoiding the need for site attendance in many cases.
Our MCS 020 assessments are designed to provide a fast, cost-effective route to compliance:
-
Fixed-cost desktop assessments with rapid turnaround
-
Noise level calculations based on manufacturer data and site layout
-
3D noise modelling where required
-
Clear confirmation of compliance (or early identification of risk)
-
Practical advice on positioning, screening or mitigation
Where installations are compliant, this allows your project to proceed without planning delay. Where potential exceedances are identified, we provide clear, pragmatic mitigation options before costs escalate.

BS 4142 Noise Impact Assessment (Planning Applications)
Where permitted development criteria cannot be met, or where required by the local authority, a full BS 4142 noise assessment is undertaken. This is a more detailed evaluation of sound from mechanical plant against the existing background noise environment.
BS 4142 assessments are commonly required where:
-
The ASHP is close to neighbouring dwelling
-
The installation is part of a commercial or multi-unit scheme
-
Local authority planning conditions require detailed assessment
-
Noise limits cannot be demonstrated via MCS 020
These assessments involve a combination of baseline noise monitoring and predictive modelling, comparing the operational noise of the ASHP against measured background sound levels to determine likely impact.
Our BS 4142 service includes:
-
Site-based baseline noise surveys (short-term or extended monitoring)
-
Rating level calculations in accordance with BS 4142 methodology
-
Detailed noise modelling and impact assessment
-
Planning-ready reports suitable for submission
-
Targeted mitigation design (acoustic enclosures, barriers, relocation)
Our focus is on delivering clear, defensible assessments that satisfy local authority requirements while minimising cost and programme risk.
Cost subject to scope starting from
£799.99
