Our Services

Sadler Energy and Environmental Services Ltd is an independent Consultancy, providing sustainable development advice to developers and builders from pre-planning stages through the construction process, providing certification and testing services on completion.
Our aim is to give impartial and pragmatic advice on all environmental issues working across a broad range of domestic and commercial developments which will enable the improved performance within the constraints of the project.

Extensions

L1B of the building regulations require extensions where there will be an amount of glazing that accounts to the equivalent of 25% of the extension floor area or when a highly glazed area, such as an orangery, is to be opened up to the main house, to demonstrate that it will not be detrimental to the overall energy performance of the property as a whole.

Conversions

Building Regulations require a SAP Assessment and Energy Performance Certificate to be produced when an existing building is converted into a new dwelling. Whilst there are not as many requirements as a new build there are certain criteria that our energy assessors will help you with, such as elemental u-values.

NEW photographic evidence requirements

Going forward the developer will need to appoint a person in charge for supplying the photo evidence to the SAP assessor on a plot-by-plot basis. What is clear from the new regulations is that the photos MUST be plot specific and will need to be geo tagged.
