Acoustic consultants across Northern Ireland
Planning-ready noise surveys, noise impact assessments and acoustic reports across Northern Ireland, from Belfast and Lisburn to Derry, Newry and Craigavon.
Northern Ireland councils assess noise through the Strategic Planning Policy Statement and their own plans, alongside the British Standards Environmental Health officers expect. We measure, assess and report against BS 8233, ProPG and BS 4142, framed around the policy your case officer will apply.

Northern Ireland planning noise requirements
Northern Ireland councils ask for acoustic evidence whenever noise could affect a new development, or a new development could affect its neighbours. These are the situations we assess most often.
New homes near the M1, M2 and A1, the Belfast to Dublin and Derry lines, or Belfast's two airports, where glazing and ventilation must be designed around noise.
Condensers, extract and heat pumps assessed to BS 4142, from city-centre restaurants to rural homes where background levels are very low.
Flats above shops and bars, and changes of use of halls, churches and commercial buildings, where neighbouring uses must be considered.
Homes near Belfast Harbour, industrial estates, quarries and late-night venues, where industrial and entertainment noise must be assessed.

Send us the detailsLocal planning knowledge
Planning in Northern Ireland is run by 11 councils, guided by the Strategic Planning Policy Statement and each council's Local Development Plan. Environmental Health teams advise on noise and often set the assessment approach.
Agreeing the scope with Environmental Health before the survey is booked is what keeps an application moving, and avoids the cost of re-surveying.

The SPPS and Local Development Plans
Northern Ireland applications are judged against the Strategic Planning Policy Statement and each council's plan, so reports reference that framework alongside BS 8233 and BS 4142.
Assessment: framed around NI policy
Belfast's two airports
Homes near Belfast City and Belfast International airports can need aircraft noise measured or modelled alongside road traffic.
Assessment: BS 8233 with aircraft noise
The M1, M2 and A1 corridors
New housing along the main road corridors faces continuous traffic noise, so layout, glazing and ventilation are designed around it.
Assessment: ProPG and BS 8233 road noise
Harbour, industry and quarries
Belfast Harbour, industrial estates and quarrying bring industrial sound close to homes, where BS 4142 applies.
Assessment: BS 4142 industrial noise
Changes of use of community buildings
Churches, halls and older commercial buildings converted to new uses need their effect on neighbours assessed.
Assessment: noise impact assessment
Quiet rural areas
In rural Northern Ireland, very low background levels mean heat pumps, farm diversification and leisure uses need careful assessment.
Assessment: BS 4142 in low-background settings

How it works
A clear, fixed-fee process built around your planning programme. You always know what is being assessed, why, and when your report will be ready.
01
Share the site address, drawings and any planning condition or EHO comments. We confirm the right assessment and send a fixed-fee quote.
02
We measure the existing noise climate with Class 1 instrumentation, including night-time and unattended monitoring where the assessment calls for it.
03
Results are assessed against BS 8233, ProPG, BS 4142 or BS 5228 as relevant, with clear, practical mitigation set out for your design team.
04
We respond to questions from planning officers and Environmental Health, and help you discharge noise-related planning conditions.
Northern Ireland noise sources
Every site has its own noise climate. We design each survey around the sources that matter at your address, measured at the right times and positions so the assessment stands up to scrutiny.
The M1, M2, M22, A1 and Westlink, plus busy routes through Belfast and the main towns.
The Belfast to Dublin Enterprise line and the lines to Derry, Larne, Bangor and Portadown.
Belfast City and Belfast International airports.
Bars, music venues and late-night uses in Belfast and the larger towns.
Air conditioning, refrigeration and kitchen extract on shops, restaurants and offices beside homes.
Belfast Harbour, manufacturing and quarrying.
Policy and guidance
Every report is framed around the policy the case officer will apply: the Strategic Planning Policy Statement, the relevant Local Development Plan and the standards Environmental Health expect.

Frequently asked questions
Straight answers to the questions developers, architects and homeowners ask us most about noise surveys and acoustic reports in Northern Ireland.
Usually, if noise could affect the people who will use the development, or the development could affect its neighbours. Common triggers are new homes near main roads, railways or airports, new plant or air conditioning, conversions near shops and bars, and late-night uses. If you're unsure, send us the site address and we'll tell you whether one is likely to be needed.
Simple noise assessments can start from around £750, and a planning noise survey and report for a small-to-medium project commonly costs £1,000–£2,500+. The fee depends on how long monitoring needs to run, the number of measurement positions and what the council requires. We always provide a fixed-fee quote. Our guide to noise assessment costs explains the main price factors.
We plan Northern Ireland surveys around your programme. Once instructed, we confirm the survey dates, duration and reporting programme with your quote, and can often work to urgent deadlines.
The acoustic standards are the same, BS 8233, ProPG and BS 4142, but the planning framework is Northern Ireland's own: the Strategic Planning Policy Statement and council Local Development Plans rather than the NPPF.
BS 8233 gives guidance on acceptable noise levels inside and around homes and other buildings. Together with ProPG, it is used to design glazing, ventilation and outdoor amenity areas for new residential development. BS 4142 assesses the impact of industrial and commercial sound, such as plant and machinery, on nearby residents by comparing it with the existing background sound level.
All of Northern Ireland, including Belfast, Lisburn, Newry, Derry, Craigavon, Ballymena and rural areas across all 11 council districts.
Often, where new plant or a heat pump is close to neighbours or the council asks for one. We assess it to BS 4142 against the existing background sound level and advise on selection, location and screening.
Yes. Where a community building is converted to a new use, we assess the noise the new use could create at neighbouring homes and set out any sound insulation or management measures needed.
A planning noise report sets out the site and proposal, the relevant policy and standards, the survey methodology and equipment, the measured results, the assessment against the applicable criteria and any mitigation needed, such as glazing, ventilation, barriers or plant attenuation. See what a noise impact assessment report includes for a full breakdown.
