Better Indoors

Better Indoors is a leading commercial and residential solutions provider to the air purification and ventilation verticals. Our products comprise the latest innovations and leading technologies. Our range of services include site surveys, air monitoring and testing plus design, specification, installation and commissioning of integrated air purification and BBA approved ventilation systems performed by industry qualified engineers. Our problem solving solutions are guaranteed with long warranties. Whether your problem is condensation and mould, or lingering odours, or you have concerns about dust mites, allergens, radon, VOCs, or sick building syndrome symptoms at home or work, or concerns about air pollution affecting indoor environments in homes, schools or hospitals, we can be trusted to properly understand your problem and then permanently solve it.

Our advanced air purification technology is unique. It was created to replicate nature’s process and is the only technology that actively purifies all of the air and surfaces at the same time. It destroys bacteria, viruses, odours and mould spores at source before they can spread and is effective against all 3 categories of indoor pollutants:

  • Particulates
  • Microbial
  • Gases

This distinguishes our technology from passive purification systems which require the air to pass through a filter and/or chamber to be treated. The difference is best described by the Sneeze Test (see which neutralised 98% of all germs before they had travelled 3 feet ! Our technology is highly effective at eliminating odours from cooking, pets, dirty socks, nappies, drying clothes and musty rooms and preventing the spread of common illnesses such as colds and flus or dangerous outbreaks such as MRSA, e-Coli and Norwalk in any populated indoor environment including homes, offices, gyms, hospitals, schools, care homes and public transport.  In fact it was deployed in subways and public buildings in China during the deadly SARS outbreak in 2003 to help prevent contagion. Originally developed in the 1980s and deployed in over 4 million products in 57 countries around the world, the technology has achieved outcomes of:

  • Reduction in absentee rates in schools
  • Prevention of infection outbreaks in healthcare facilities
  • Improved office/workplace productivity
  • Prevention of bacterial/viral illnesses in elite sports teams
  • Improved building occupant health and well being
  • Major saving in HVAC and ductwork system cleaning and maintenance costs
  • Reduced energy consumption costs/carbon footprint

Our expertise also extends into air pollution control initiatives where we recently consulted on solutions that help towns and cities improve outdoor air quality around schools, hospitals, residential areas and other urban facilities that are located in areas of high traffic and NOX pollution.

FTA is one of the biggest business groups in the UK, supporting, shaping and standing up for efficient logistics. We are the only organisation in the UK that represents all of logistics, with members from the road, rail, sea and air industries, as well as the buyers of freight services such as retailers and manufacturers whose businesses depend on the efficient movement of goods. As champions and challengers, FTA speaks to Government with one voice on behalf of the whole sector, greatly increasing the impact of our messages and achieving amazing results for Members.

FTA supports the Logistics Emissions Reduction Scheme (LERS), an industry-led scheme dedicated to recording, reporting and reducing carbon emissions from freight. The latest data released in the LERS eighth Annual Report Update shows that LERS members registered average emissions levels 13 per cent per vehicle km lower than in the wider logistics industry. This reduction in emissions directly led to a similar saving in fuel costs. The LERS demonstrates how supply chains can reduce carbon emissions through voluntary agreements rather than regulation and shows how businesses and the environment can benefit from sharing best practice.

FTA is also supporting logistics in meeting carbon reduction targets by promoting and supporting the use of alternative fuels. Operators of national heavy goods vehicle fleets are considering wider use of natural gas and biomethane powered vehicles to help achieve operational efficiencies and reduce carbon emissions. To support this FTA has developed a natural gas-powered heavy goods vehicles manifesto for achieving breakthrough in the take-up of natural gas-powered heavy goods vehicles.

GEM Air Quality Ltd

GEM Air Quality Ltd are independent air quality consultants, specialising in air quality assessments for planning and Environmental Impact Assessment (EIA) purposes.

These assessments typically examine the impact of both the construction and operational phases of a particular development.  The impacts are compared against UK air quality objectives and/or significance criteria defined within relevant air quality guidance.

Depending on the scale of these impacts the air quality assessment may also discuss the mitigation measures that will need to be adopted.  Such measures will focus on the reduction of emissions during the construction phase, plus any measures relating to the introduction of new exposure into an area of existing poor air quality and/or the wider impacts of a proposed development on local air quality.

Following publication of the London Plan and the Mayor of London’s Sustainable Design and Control Supplementary Planning Guidance (SPG) we also undertake “Air Quality Neutral” assessments, which are now required for all major new developments.  These assessments focus on the building and transport emissions over a year and compare these with a benchmarked emission rate.

Established in early 2009, GEM Air Quality Ltd has established a wide customer base, including planners, architects and developers.  Through its employees, GEM Air Quality Ltd has over 12 years experience in the field of air quality assessment and monitoring having completed numerous air quality assessments and monitoring projects.

Give a Car

How the Giveacar Scheme Works

Giveacar is an organisation that is festooned in the art of turning a negative into a positive. By embracing unwanted, neglected or unusable cars and donating the proceeds raised through scrap or auction to charity, we are giving a new lease of life to both the vehicle that’s donated and the causes they support. Sandwiched between the charity sector and commercial re-sale of scrap metal and motor vehicles, we continue to be the trusted leader within the car donations service.

Our scrap car partners have sites strategically placed up and down the country, all of which are registered as Authorised Treatment Facilities and are regulated by the Environment Agency. We always provide our donors with a Certificate of Destruction as evidence that their vehicle has been recycled in accordance with proper etiquette. These are the key ingredients TfL require in order to gain eligibility for their scrappage scheme, therefore perfectly establishing Giveacar as the means with which people can join the TfL scheme.

As a not-for-profit social enterprise, our sole income is generated through our admin fee. With vehicles that have a value of £149 and below we take a 25% fee, and vehicles worth £150+ we take an additional 5%. Many of our customers are happy to proceed on this basis, most notably because we communicate to them that with every £1 that’s donated we raise £11.30 for other charities, therefore maximising every donation we receive.

That’s Giveacar. We are the market experts and are driven towards a more charitable and sustainable environment.

GRAMM SmogStop

GRAMM is the UK leading specialist in the design, supply & installation of environmental acoustic barriers with over 20 years of experience. We have constructed literally 1,000’s of Km’s of acoustic barriers of all types of materials throughout the UK and Europe.

GRAMM is the exclusive UK partner for SmogStop.

GRAMM SmogStop Barrier reduces air and noise pollution levels in surrounding neighbourhoods, and takes a two-pronged approach to reducing air pollution from major roads, highways and railways.

The patented aerodynamic design reduces pollution levels by enhancing dispersion so that neighbouring residents can breathe easier. At the same time, a proprietary coating on the barrier actually breaks down the NOx and VOCs that produce smog, transforming them into harmless by-products.

GRAMM SmogStop Barrier’s angled baffle and double-walled design serve two main purposes. First, they direct traffic emissions between the two walls, where a photo catalytic coating treats the pollutants. Second, they generate vortexes and enhance vertical mixing of emissions with clean air, further decreasing pollution levels in surrounding neighbourhoods.

The proprietary coating we’ve developed transforms smog-producing NOX and VOCs into harmless gases and water, powered purely by sunlight.

GRAMM SmogStop Barrier incorporates ClearSoundBlok: a sound-reducing, break-resistant and highly transparent grade of acrylic.

The result? A dramatic reduction in noise and air pollution — without sacrificing sunlight.

Over the course of a year, a single kilometre of GRAMM SmogStop Barrier can remove 16 tonnes of NOX— the equivalent of taking 200,000 cars off that stretch of road.

Turnkey Instruments

Turnkey Instruments Ltd. design and manufacture a range of easy-to-use dust monitors, created to continuously measure and record the concentration of airborne particles. Our instruments feature two modes; in environmental mode they can simultaneously monitor the concentrations of TSP, PM10, PM2.5 and PM1 particles, while their workplace mode monitors the inhalable, thoracic and respirable fractions. In addition, they all include a data logging feature.

Every product includes a proprietary nephelometer, designed and produced by ourselves, that analyses the individual particles of an air sample as they pass through a laser beam; the particles are then collected on the reference filter. This advanced technology allows fractions to be determined at concentrations up to several mg/m³.

Our product range includes DustMate, Osiris and Topas. DustMate is a hand-held detector ideal for short term sampling and is highly effective for monitoring air quality within buildings and clean rooms, Osiris is a small and compact instrument designed to study particulate monitoring on a short to long term basis, used to determine exceedance areas while Topas is a fixed station monitor designed for long term installation. With Topas/Osiris, several sites can be linked together to form a larger monitoring system, controlled by our web server, using the 3G and 4G data network. Additionally, our latest noise monitor, i-dB &iVIBE can be used with both Osiris and Topas to create a full site monitoring station, designed to monitor both dust and noise & vibration emissions to meet all regulations.

iGASair is a new internet gas monitor from Turnkey. Its multiple gas sensors are housed within a shielded manifold and aspirated with an ultra-quiet pump, making the instrument equally suitable for both outdoor and indoor air pollution monitoring.Carbon dioxide is detected by means of a nondispersive infrared (NDIR) detector, VOCs (isobutylene) by a 10.6 eV photoionization detector (PID), and the other gas species by means of 4-electrode electrochemical cells. A proprietary zero gas generation scheme is employed to eliminate zero drift in all of the gas sensor cells.
