Noise objections delaying approval?

We resolve them with BS4142/BS8233 Noise Impact Assessments, mitigation design, and council/EA liaison.

Independent reports led by Chartered engineers

Environmentally Sound Limited provides independent Noise Impact Assessments (NIA) that unlock approvals for developments in Milton Keynes and within a 30-mile radius. Each project is led by our Chartered Mechanical & Acoustic Engineers, and we bring in trusted specialists when required — ensuring every assessment is accurate, defensible, and tailored to the problem at hand.

What is a Noise Impact Assessment?

An NIA evaluates how your scheme affects nearby receptors — and how existing noise sources affect your site. Local Planning Authorities (LPA) and Environmental Health Officers (EHO) frequently require an NIA before granting approval.

What our assessment includes

  • Baseline monitoring using precision sound level meters.

  • Prediction of operational and construction noise using accepted calculation and modelling methods.

  • Assessment against BS4142, BS8233, NPSE, and NPPF.

  • Practical mitigation: acoustic glazing, barriers/bunds, layout optimisation, operational limits, and (where appropriate) engineering refinements at source.

  • Stakeholder liaison: we engage early with councils and the Environment Agency to agree scope and avoid rework.

When you’ll need an NIA

  • Residential developments (demonstrate BS8233 internal noise criteria).

  • Industrial/commercial sites (plant/deliveries assessed under BS4142).

  • Transport exposure (road, rail, aircraft) for new buildings.

  • Mixed-use schemes combining housing with retail/leisure.

For major schemes, the NIA may form part of an Environmental Impact Assessment (EIA).

Why choose Environmentally Sound

  • Led by Chartered engineers with 29 years’ experience in acoustics, vibration, and mechanical design.

  • A flexible consultancy model — we assemble the right specialists for each project, ensuring the exact expertise you need without unnecessary overheads.

  • Local expertise across Milton Keynes, Newport Pagnell, Bedford, Northampton, Aylesbury, and Luton.

  • Reports routinely accepted by Milton Keynes Council, Bedford Borough Council, Central Bedfordshire Council, and Buckinghamshire Council.

  • Independent and insured consultancy for robust, impartial reporting.

If predicted noise is too high

  • Low-noise plant specification and acoustic enclosures.

  • Barriers/bunds, screening, and source–receiver re-layout.

  • Enhanced façades: acoustic glazing and attenuated ventilation.

  • Operational controls and timing restrictions.

Cost and timescale

  • Typical NIAs start from £800 (scope and monitoring drive cost).

  • Delivery aligned to planning submission deadlines.

Local example — Newport Pagnell

BS4142 noise assessment for an air source heat pump (ASHP)

  • Initial MCS020 application was refused for exceeding permissible sound limits.

  • We completed baseline monitoring (Rion NL-53) and prepared a BS4142 report.

  • Result: ASHP was 6 dB below background at the nearest receptor.

  • Planning permission granted by Milton Keynes Council within two weeks of submission.
