If you’re planning a development anywhere in Greater London, there’s one requirement you can’t skip: your scheme must be air quality neutral. Get it wrong, and your planning application can be delayed or refused. Get it right, and it’s usually a straightforward part of your submission. This guide explains exactly what air quality neutral means, how the benchmarks work, what a full assessment involves, and the mistakes that catch developers out. We’ve kept it plain and practical, with a worked example and a real project to show you how it plays out. What is air quality neutral? Air quality neutral means your development won’t add more pollution to London’s air than a set benchmark allows. It doesn’t mean zero emissions. It means your building and transport emissions stay at or below the levels the Greater London Authority (GLA) has defined as acceptable for your type and size of development. The policy comes from Policy SI1 of the London Plan. It was brought in because lots of small developments, each adding a little pollution, were quietly making London’s air worse over time. Every scheme individually looked harmless, but together they added up. Air quality neutral tackles that by putting a cap on each new development. The rule is simple: every development proposal in Greater London must be at least air quality neutral, or risk refusal. Which pollutants and emission sources are assessed? An air quality neutral assessment looks at two pollutants: nitrogen oxides (NOx) and fine particulate matter (PM2.5). The older 2014 guidance used PM10, but the current guidance switched to PM2.5 because the health evidence around fine particles is much stronger. Your emissions are measured against two benchmarks: The Building Emissions Benchmark (BEB) — emissions from your heating and energy systems, such as gas boilers, CHP plant, or backup generators. The Transport Emissions Benchmark (TEB) — emissions from the vehicle trips your development generates. Your proposal has to meet both benchmarks. Passing one but failing the other means your scheme is not air quality neutral. How the benchmarks work The benchmark you’re measured against depends on what you’re building and where. For building emissions, the allowance depends on your land use (residential, office, retail, industrial) and your heating system. Here’s the key point that shapes most modern schemes: a development using 100% electric heating, such as air source heat pumps, produces no on-site NOx and automatically meets the Building Emissions Benchmark. For PM2.5, the building benchmark is effectively zero, which means biomass boilers and most on site combustion plant will not pass unless they’re genuine emergency backup. For transport emissions, the allowance depends on your land use and your location the Central Activities Zone, Inner London, and Outer London all have different trip rate benchmarks. Central London has better public transport, so lower car trip rates are expected there. Simplified vs full assessment: which do you need? Not every development needs a full set of calculations. The guidance splits assessments into two routes. Feature Simplified Procedure Full (Detailed) Procedure Applies to Minor developments, and major developments with no additional emission sources All major developments, and any scheme that fails the simplified criteria Building emissions Passes if heating is a heat pump/zero-emission source, an ultra-low NOx boiler (≤40 mg/kWh), or connects to an existing heat network Full BEB calculation using heating system and expected energy demand Transport emissions Passes if car-free, or parking is within London Plan maximum standards (Policies T6–T6.5) Full TEB calculation using predicted vehicle trips from a transport assessment Report output Short air quality neutral statement with summary tables Detailed section within the wider air quality assessment, with full calculations Consultant needed? Often not essential, but recommended Yes — specialist input strongly advised One important catch: if your site sits inside an Air Quality Focus Area a part of London with especially poor air quality your local planning authority can insist on a full assessment even for a minor development. A worked example (so you can see how it adds up) Let’s take a simple case. Imagine a small residential block in Inner London. The consultant calculates the Building Emissions Benchmark for the scheme’s floor area say the total BEB comes out at 161.7 kg of NOx per year. The proposed development, using an efficient low-NOx boiler system, produces 84 kg of NOx per year. Because 84 kg is comfortably below the 161.7 kg benchmark, the development passes for building emissions and is air quality neutral on that measure. The same scheme is then tested for transport. If the predicted car trips generate emissions above the Transport Emissions Benchmark, the scheme fails on transport even though it passed on buildings. At that point the design has to change, usually by cutting parking spaces, before it can be called air quality neutral. This is the trap most developers miss: you have to pass both, and transport is where schemes usually fall down. What happens if your development is not air quality neutral? If your assessment shows you’re over a benchmark, the guidance sets out a clear order of steps and offsetting money is genuinely the last resort. Air quality neutral vs air quality positive: what’s the difference? These two terms get mixed up constantly, so here’s the plain version. Air quality neutral London plan means no net increase in emissions above the benchmark. Air quality positive goes further it means your development actively improves air quality compared to the baseline. Air quality positive is currently expected mainly on large, strategic masterplan schemes, and it usually involves things like fully zero emission heating, car free layouts, and strong active travel provision. For most developments, air quality neutral is the requirement you need to meet. A real project example We recently supported a mid sized residential scheme in an Inner London borough that had failed its first air quality neutral check on transport emissions. The original design included too much car parking for its location. Rather than heading straight for an expensive offsetting payment, we reworked the transport inputs, reduced
If you’ve landed here, there’s a good chance a planning officer has just told you that you need an air quality assessment and you’re not entirely sure what that means, whether you really need it, or what it’s going to cost you. That’s completely normal. It’s one of those planning requirements that sounds far more complicated than it actually is, and getting a straight answer online is surprisingly hard. What is an air quality assessment planning? An air quality assessment (AQA) is a technical report, put together by a qualified air quality consultant, that your local planning authority uses to decide whether your development is acceptable when it comes to air pollution. Here’s the bit most people miss: it works in two directions at once. First, it looks at what your development will do to the surrounding air think extra cars on the road, dust kicked up during construction, or fumes from a biomass boiler. Second, it looks at what the existing air will do to your development which really matters if you’re putting homes, a school or a care home next to a busy road where the air is already poor. That second point catches a lot of developers out. You can have a scheme that barely adds any pollution itself, but if you’re placing new residents somewhere the air already breaches legal limits, the council will still want an assessment. It’s about protecting the people who’ll move in, not just the neighbours. The report is built around the rules that matter in the UK the National Planning Policy Framework, Defra’s Local Air Quality Management guidance, and the Institute of Air Quality Management (IAQM) methodology plus whatever your specific council asks for in its local planning policy. In practice, three things do most of the damage to air quality in the UK: nitrogen dioxide (NO₂), tiny particles called particulate matter (PM₁₀ and PM₂.₅), and construction dust. Traffic is the main culprit for the first two, which is why almost every assessment ends up looking closely at how many extra vehicles your development will bring. When do you actually need an air quality assessment? This is the question everyone wants answered, so let’s be direct. The council has the final say, and every authority is slightly different but based on IAQM guidance and the validation rules most UK councils publish, you’ll usually need an assessment if any one of these is true: A quick self check: do you need one? Run through this. A “yes” to any of these means you very probably need an assessment, and it’s worth confirming the details with a consultant or the council’s environmental health officer before you submit: Honestly, if you’re in a city and building anything of a decent size, the safe assumption is that you’ll need at least a basic assessment. It’s far cheaper to check early than to have your application bounced back weeks down the line. The two types of assessment and which one you’ll need Not all air quality assessments are the same, and the difference matters for your budget and your timeline. It really comes down to one thing: whether the consultant needs to build a dispersion model (a computer model that predicts exactly how pollution spreads). Feature Basic (Screening) Assessment Detailed Assessment Also known as Baseline or screening assessment Air Quality Impact Assessment Uses dispersion modelling? No Yes — usually ADMS-Roads Best for Smaller, lower-risk developments Major schemes, sites in AQMAs, high-traffic locations What’s involved Baseline air review, construction dust risk, traffic screening Everything in a basic assessment, plus modelled pollution levels at specific homes and receptors Typical cost £500–£1,200 £1,500–£4,000+ Typical timescale 1–2 weeks 3–6 weeks (longer if new monitoring is needed) Basic (screening) assessment A basic assessment sets the scene. Your consultant pulls together existing data the council’s own monitoring, Defra’s background pollution maps, and the context of your site to work out what the air is like right now. They then check your development’s expected traffic against the IAQM screening thresholds to see whether a fuller study is needed. Most basic assessments also include a construction dust risk assessment. If your traffic numbers come in under the thresholds and future residents won’t be exposed to unsafe pollution, a basic assessment is often all the council needs. Detailed assessment (Air Quality Impact Assessment) For bigger schemes, or anything in an AQMA, you’ll need the full version. Here the consultant builds a dispersion model nearly always ADMS-Roads to predict pollution levels at specific spots: the new homes, the school across the road, whatever’s nearby and sensitive. Those predicted figures get compared against the UK’s legal air quality objectives, like the 40 µg/m³ annual average for NO₂. If your development pushes things over the line, you’ll then need to look at mitigation. What actually happens during an assessment the process step by step People often imagine this is some mysterious black box. It isn’t. Here’s how it actually runs: The 2024 IAQM dust guidance the update most articles miss Here’s something you won’t find in most of the guides currently ranking for this topic, and it genuinely matters. In 2024, the IAQM published a substantial update to its guidance on assessing dust from demolition and construction the version most people call V2.2. Since nearly every council in the country leans on this exact methodology for construction dust, the update changes how dust risk gets worked out on real projects, which in turn changes the mitigation and monitoring you’ll be asked to put in place. The headline change is in how the “dust emission magnitude” is defined for the four activities demolition, earthworks, construction and trackout. In plain terms, some projects that used to screen as higher risk now land in a lower category, and some the other way round. That directly affects what you’ll need to do on site. Why should you care? Because if your consultant is still quietly using the old 2014 method, your dust assessment could specify the wrong level of control either

Introduction When many people live close together, it is hard to keep the air clean. In cities like London, there is a lot of traffic and many factories. These can make the air dirty. Air Quality Neutral is very important. It helps make sure that new buildings do not make the air worse. This keeps people healthy. In this article, I will explain what Air Quality Neutral means. I will talk about why it is important. I will also explain how we check the air quality. Lastly, I will share how Freshbreeze helps make the air cleaner for everyone. What does Air Quality Neutral London Plan Guidance mean? Air Quality Neutral is a regulation laid down by Greater London Authority (GLA). It defines that new construction should not contribute more pollution than that allowed. It also create buildings meeting the air quality standards applicable to the site. This makes it much cleaner and safer for everyone involved. Key Components of AQN Building Emissions Benchmark (BEB): This checks how much energy buildings use for heating. Because of this, new buildings use technology that saves energy. This helps lower costs and keeps the air cleaner. Transport Emissions Benchmark (TEB): This standard measures the pollution from cars that travel. This rule encourages developers to find ways to be more eco-friendly. They can add things. Like public transport, nearby, bike parking, and electric vehicle charging stations. Why Do We Need It? Air Quality Neutral guidance is important because there are growing concerns. This is about how air pollution affects people and the environment. Air pollution can cause many diseases and health problems. It especially harms the lungs and heart, leading to early deaths. This is why we need rules like Air Quality Neutral to help keep our air clean and safe for everyone. By implementing AQN policies, London aims to: – Reduce Overall Emissions: The guidance concerns cuts in nitrogen oxides (NOx) and particulate matter (PM10). Two of the most notorious pollutants for city air. – Encourage Sustainable Transportation: In a way which supports cycle use and public transport. As options to car use the AQN guidance does serve to reduce emissions-related from traffic. – Promote Zero-Emission Heating Systems: New developments should use sources of energy. They do not harm the environment protecting it from pollution. Another environmentalist said, “Such guidance is timely as more cities seek to reduce pollution while pursuing development.”For more details Click Here How Has This Guidance Been Prepared? The AQN guidelines have been created through research and discussions with experts. In the environment, city planners, and other interested groups. The Greater London Authority (GLA) studied real air quality data to set realistic standards. They looked at current air quality levels and what might happen in the future. This means they want to make sure that new buildings do not make the air worse. They want to keep the air clean and safe for everyone. What is New in the Changed Guidance Recent changes have also increased the usage of AQN from large scale projects to all new builds in London. This shift says this aspect requires focus at the lowest level of development. So, that every project will impact positively on the city in terms of air quality.

How does a development get AQN status? To qualify for AQN status, a development required to prove that their building and transport emissions are below certain set levels. If emissions go over these levels, then some form of control or an equivalent in money may be needed. What are the best ways to respond to the mitigation? Mitigation strategies may include: Realizing energy efficient heaters for heating. Self-promoting public transport use or providing appropriate bicycle parking space. Adding trees or any form of landscape to created to enhance the quality of air in the interior or exterior environment respectively. How Freshbreeze help in the compliance of AQN?

7 Must-Know Facts for a Healthier Homeffect Air Quality Introduction – Why Seasonal Air Quality Shouldn’t Be Ignored As crisp autumn mornings shift into the colder clutches of winter, most people focus on staying warm. But there’s an invisible factor that often gets overlooked, air quality, especially indoors. At Freshbreeze Environmental Ltd, we’ve seen how seasonal changes drastically affect the air we breathe, and the health implications can be serious. Whether it’s trapped pollutants, increased heating emissions, or poor ventilation, indoor air quality (IAQ) during colder months deserves urgent attention. Understanding the Science Behind Indoor Air Quality Indoor air quality refers to the cleanliness and chemical composition of the air inside buildings. Unlike outdoor air, which disperses pollutants more freely, indoor air can become a concentrated mix of harmful substances. Common Indoor Pollutants Include: When poorly managed, these pollutants can pose real risks to health and well-being, especially during the seasons when we spend most of our time indoors. How Weather Changes Influence Air Quality As temperatures drop, several environmental factors come into play, affecting both outdoor and indoor air quality: Temperature Inversions Normally, warmer air rises and carries pollutants upward. But in winter, temperature inversions trap a layer of cold air near the ground. This also traps: The result? Air pollution becomes concentrated right where we live and breathe. Increased Use of Heating Systems During winter, we rely on heaters and stoves to stay warm but many traditional systems… especially wood-burning stoves or older furnaces release a surprising amount of indoor air pollutants. Without proper ventilation or filtering, you’re circulating contaminated air. The Problem with Reduced Ventilation in Winter Closing windows keeps the cold out, but it also traps pollutants. VOCs, carbon dioxide, and airborne allergens have nowhere to escape, which leads to stale, unhealthy air. Reduced Ventilation In colder weather, we tend to close windows and seal homes for warmth. This results in less natural ventilation, trapping indoor pollutants such as volatile organic compounds (VOCs), carbon dioxide (CO2), and household dust, leading to poor air quality inside homes and offices. The Hidden Health Risks of Poor Air Quality in Cold Weather Respiratory and Allergy Issues Exposure to VOC’s and particulates can trigger: General Discomfort and Cognitive Fatigue Even for those without allergies, poor air can lead to: Lack of concentration Headaches Brain fog How Freshbreeze Environmental Ltd Can Help Air/ Indoor Quality Assessments The good news is, there are solutions!
