Energy Rated Windows
The UK government is committed to reducing levels of carbon dioxide emissions throughout the United Kingdom and utilising energy as cost-effectively as possible. When you consider replacing windows and doors, it is equally important to consider your energy expenditure and costs.
Our Energy Rated windows are independently tested and verified by the British Fenestration Registration Certification Authority and recognised by the Energy Trust. All windows are available in a variety of energy-efficiency levels from A to C, conforming with or surpassing building regulations in current legislation.
