Any significant addition or change to an external appearance of a building usually requires planning permission, from your Local Authority. Certain projects might only need to be dealt with under ‘permitted’ development rights, however this is limited to a specified extended. H & C can guide you through the planning process.
To encourage developers, and even householders to build more energy efficient buildings, the Government, has set Targets for Co2 emissions from new and refurbished properties. We have an in house accredited Assessor for both Code and Bream Refurbishment schemes that can produce these reports as required.
