🔊 Top reasons Noise Impact Assessments cause delays

A Noise Impact Assessment doesn't usually "fail" because of the assessment itself. More often, delays happen because key considerations weren't addressed early enough in the project.

See the graphic below for some of the most common issues...

The earlier potential noise issues are identified, the easier they are to address. Whether it's changes to glazing, ventilation, site layout, or acoustic design, making informed decisions early can help avoid redesigns and keep your project moving.

A Noise Impact Assessment isn't just about meeting planning requirements, it's about understanding potential risks before they become costly problems.

Need advice on whether your site requires a Noise Impact Assessment? Get in touch with our team.

🔊 What does an acoustic consultant actually do on a building project?

Acoustic consultancy isn't just for theatres, music venues, or recording studios.

On residential developments, acoustic consultants play an important role in helping buildings achieve the required levels of sound insulation and occupant comfort.

This can include advising on:
✔️ Wall, floor, and ceiling constructions to meet Part E of the Building Regulations
✔️ Sound insulation between flats and adjoining homes ✔️ Mechanical plant and service noise
✔️ Room acoustics for shared spaces
✔️ External noise affecting the development

By considering acoustics early in the design process, developers can reduce the risk of costly redesigns, failed testing and occupant complaints after handover.

Good acoustic design isn't just about compliance, it's about creating buildings that people enjoy living in.

Have a question about acoustic consultancy or Part E requirements? We'd be happy to help.

What is ventilation commissioning and when is it required?

Installing a ventilation system is only part of the process.

Before a new dwelling can achieve Building Regulations sign-off, the system must be commissioned to demonstrate that it's performing as designed.

Under Part F of the Building Regulations, ventilation commissioning verifies that systems such as:
✔️ MVHR (Mechanical Ventilation with Heat Recovery)
✔️ MEV (Mechanical Extract Ventilation)
✔️ Intermittent extract fans have been installed correctly and are delivering the required airflow to each room.

The commissioning results are recorded and form an important part of the compliance process.

By testing and verifying performance before handover, developers can reduce the risk of delays and ensure buildings provide the healthy indoor environment they were designed to achieve.

Have a question about Part F or ventilation commissioning? Our team is here to help.

💧 What is a water usage calculation and what does it prove?

Water usage calculations are used to demonstrate compliance with Part G of the Building Regulations, which sets limits on water consumption in new dwellings.

The calculation assesses the specification of:
✔️ Taps
✔️ Showers
✔️ Baths
✔️ Toilets
✔️ Water-using appliances

Using the flow rates and capacities of these products, the calculation determines whether the property will meet the required water consumption target of 125 litres per person per day, or, in some areas, the more stringent 110 litres per person per day standard.

It's a small detail that can have a significant impact on compliance, making product specification an important consideration early in the design process.

Have a question about Part G compliance or water usage calculations? Get in touch.

Building Regulations compliance isn't just about passing tests.

Increasingly, regulations are focused on demonstrating real-world building performance through evidence, calculations, testing and documented decision-making.

The earlier compliance is considered, the smoother project delivery tends to be.

🌱 It's not just about solar panels. Here's what a Sustainability Statement actually covers...

A Sustainability Statement explains how a development contributes to sustainable development across three key areas:
🌍 Environmental sustainability
👥 Social sustainability
📈 Economic sustainability

Many local authorities require Sustainability Statements for medium and large-scale developments as part of the planning process.

They can cover a wide range of topics, including:
✔️ Energy and carbon reduction
✔️ Biodiversity and green infrastructure
✔️ Water efficiency
✔️ Sustainable transport
✔️ Community benefits
✔️ Materials and resource use

In simple terms, it's an opportunity to demonstrate how a development will positively contribute to the area beyond the buildings themselves.

As planning policy continues to evolve, Sustainability Statements are becoming an increasingly important part of the planning submission process.

🌡️ What is an overheating assessment?

As UK summers become warmer, overheating in homes is becoming a growing consideration for developers, designers and building owners.

Introduced under Part O of the Building Regulations in 2022, overheating assessments are designed to demonstrate that new homes will remain comfortable during hot weather and won't be at risk of excessive heat build-up.

Depending on the project, compliance can be demonstrated through:
✔️ Simplified Part O assessments
✔️ TM59 dynamic thermal modelling

Getting overheating assessments right at the design stage can help avoid costly redesigns later and keep projects moving smoothly through the approval process.

Have a question about Part O or overheating assessments? We'd be happy to help.

🏡 What is a SAP calculation and do you actually need one?

It's one of the most common questions we get asked.

If you're building a new home in England or Wales, a SAP calculation is a requirement for Building Regulations compliance.

It assesses the energy performance of the dwelling by considering factors such as:
✔️ Insulation
✔️ Windows and doors
✔️ Heating systems
✔️ Ventilation
✔️ Renewable technologies

The results are used to demonstrate compliance and support building control sign-off.

💨 Top Tip: Schedule air tightness testing before glazing is fully completed to help avoid costly rework later.

Identifying potential leakage issues earlier in the programme gives you more opportunity to resolve them quickly and efficiently, before final finishes and sign-off deadlines become a pressure point.

A little forward planning can save significant time, cost, and disruption later in the project.
