Our Services
At Ratio Seven, we take pride in offering a wide array of services that cater to the construction sector’s unique requirements. Our services include:
Air Testing Hereford
Air Pressure Testing is a crucial aspect of building assessment in the UK. This process involves the evaluation of the air pressure within your building with the aim of optimising ventilation and enhancing energy efficiency.
In the context of the UK’s construction and environmental regulations, assessing air pressure becomes imperative to ensure that your building complies with the necessary standards. The British construction industry places a strong emphasis on creating energy-efficient structures, and one of the key factors in achieving this is maintaining optimal air pressure.
Air Permeability Testing
Ensuring that your construction meets the required air permeability standards is a critical step in achieving energy efficiency and compliance with UK building regulations. In the United Kingdom, there are strict guidelines in place to control the level of air leakage in buildings, and meeting these standards is essential for both environmental and cost-saving reasons.
SAP Calculations Hereford
Accurate SAP (Standard Assessment Procedure) calculations for energy efficiency compliance. Our expert team can assess your building’s energy performance, providing you with valuable insights on how to improve energy efficiency and reduce carbon emissions. By utilising advanced software and industry knowledge, we help you make informed decisions regarding insulation, heating, and ventilation systems.

Air Pressure Testing
Evaluating the air pressure within your building is a crucial step in optimising ventilation and enhancing energy efficiency, especially in the context of the construction and environmental standards. The UK places a strong emphasis on creating sustainable and energy-efficient buildings, and assessing air pressure is integral to achieving these goals.
Door Blower Testing
Testing the performance of doors and windows for air tightness and security is a crucial aspect of ensuring the overall efficiency, comfort, and safety of a building. This evaluation aligns with the country’s construction standards and regulations, which emphasise the importance of energy efficiency and security.
Heat Loss Surveys
Identifying areas of heat loss and improving energy efficiency is of paramount importance, where energy-efficient building practices are highly valued for their environmental and cost-saving benefits.
Thermal Imaging
One effective method for identifying areas of heat loss is through thermal imaging. This technology allows you to visualise temperature variations in your building’s envelope, revealing areas where insulation may be inadequate or where air leakage is occurring. Thermal imaging can be particularly useful in pinpointing problem areas, such as poorly insulated walls, roofs, or windows.
Building Consultancy Services
Obtaining expert advice and consultancy tailored to your project’s needs is a prudent step in ensuring the success and efficiency of any construction or building-related endeavour.
Experienced consultants can provide invaluable insights during the initial planning and design stages of your project. They can help you make informed decisions regarding materials, building methods, and energy-efficient design principles, ensuring your project aligns with your goals and meets regulatory requirements.

In the world of construction, ensuring the quality and safety of a building is of paramount importance. It’s not just about aesthetics; it’s about functionality, energy efficiency, and compliance with building regulations. This is where air testing plays a significant role.
Air Testing Explained
Air testing, in simple terms, is the process of measuring how airtight a building is. It evaluates the ability of a building’s envelope (the outer shell, including walls, roof, and floors) to prevent the uncontrolled flow of air in and out of the structure. Why is this important? Because unwanted air leakage can lead to several issues:
- Energy Inefficiency: Air leakage allows conditioned air (heated or cooled) to escape, leading to increased energy consumption and higher utility bills.
- Comfort Issues: Drafts caused by air leakage can make indoor spaces uncomfortable, affecting the well-being of occupants.
- Moisture Problems: Air leakage can allow moisture to enter the building, potentially leading to mould and structural damage.
- Compliance: Many building codes and regulations require a certain level of airtightness to be met for new constructions.
The Role of Air Permeability Testing Hereford
Air permeability testing, often referred to as the “blower door test,” is a key component of air testing. During this test, a special fan is used to depressurise or pressurise the building, simulating the effect of wind or temperature differences. The airflow rate required to maintain the pressure difference is then measured.
By conducting air permeability testing, we can determine the air permeability of your building, expressed as an air changes per hour (ACH) value. This value indicates how many times the volume of air within the building is replaced in one hour due to leaks.
The Importance of SAP Calculations
SAP calculations, are another crucial service provided by Ratio Seven. SAP calculations are a fundamental part of assessing the energy performance of a building, particulally in the UK.
What Are SAP Calculations?
The Standard Assessment Procedure (SAP) is a methodology approved by the UK government for calculating and comparing the energy and environmental performance of residential buildings. It takes into account various factors, including:
- Thermal insulation
- Heating systems
- Ventilation
- Renewable energy sources
- Building fabric
SAP calculations result in an energy performance certificate (EPC), which provides an energy efficiency rating for a property. This rating not only determines compliance with building regulations but also influences potential buyers and tenants.
Why SAP Calculations Matter
- Compliance: Meeting the required SAP score is essential for compliance with building regulations in the UK. Failing to do so can result in costly delays and rework.
- Energy Efficiency: SAP calculations help identify areas where energy efficiency can be improved. This can lead to long-term cost savings and a reduced carbon footprint.
- Marketability: A higher SAP rating can make your property more attractive to potential buyers or tenants, as it indicates lower energy bills and a more comfortable living environment.
