What does it all mean?
If you’re thinking of refreshing or renovating your conservatory roof, then the chances are you’re going to come across some industry jargon. It’s almost part and parcel of understanding what are the best products and who are the best tradesmen. So in this post, we’re going to provide you with an “all you need to know” guide of some of the terms you may come across and what they mean.
Local Authority Building Control
One of the first expression you may come across is LABC. Local Authority Building Control (LABC) is a not-for-profit membership organisation that represents all local authority building control teams in England and Wales. If you are having any work done to your conservatory roof, you should ensure your contractors are registered with them. 2Hot2Cold is LABC registered and that means:
- Helps us ensure acceptance of proposed works by all local authorities across England, Wales and Scotland
- Makes the building control process faster, easier and cheaper by simplifying the submission route
- Provides both us and you with a readymade library of rigorously checked systems and products
- Ensures easier structural warranty approval through our association with our colleagues at LABC Warranty
For additional information about your LABC please see: https://www.labc.co.uk/
An ETA is an approval based on testing carried out to agreed European levels. Where a product is completely new or innovative, testing may take the form of an individual assessment carried out under bespoke requirements detailed within a European Assessment Document (EAD).

The Standard Assessment Procedure (SAP) is a methodology introduced by the Government to assess and compare the energy and environmental performance of buildings to make sure that any new developments will not only meet Building Regulations, but also all energy and environmental policy initiatives. The principle aim is to assess how much energy a new development will consume, when delivering a defined level of comfort and service provision using standard assumptions for occupancy and behaviour. This process also standardises the assessments of dwelling energy performance so that like for like comparisons can be made nationwide.
How are SAP calculations done?
SAP calculations are based on the energy balance of a new development, considering a range of factors that contribute to energy efficiency, such as:
- materials used for the construction
- thermal insulation of the building fabric
- air leakage characteristics of the dwelling, and performance of ventilation equipment
- efficiency and control of the heating systems
- solar gains through openings in the dwelling
- the fuel used to provide space and water heating, ventilation and lighting
- energy for space cooling
- renewable energy technologies
The calculation does not include individual characteristics of the household such as household size and heating patterns and temperatures. SAP calculations can also determine fuel costs and the Environmental Impact Rating via the emissions of carbon dioxide (CO2).
Why are SAP calculations important?
SAP assessments have been a legal requirement for all new-build, domestic properties in the UK under Part L of Building Regulations since 1995. Homes must achieve a ‘Pass’ on these calculations for the project to pass Building Regulations. Without this, a property will not be signed off by Building Control and may not legally be listed for rent or sale.
As so many of the elements of the assessment are related to the construction of the development, it is strongly advised that the SAP scores are calculated and considered at the beginning of the project in order to best inform architects, builders, surveyors and suppliers. Achieving a pass on the SAP calculation can involve numerous important initial design decisions.
Alongside the regulatory aspect, there are other reasons why it is vitally important to consider your SAP score long before project completion. Factors such as energy consumption and carbon output can be accurately predicted and the running costs of the home minimalised from an early-stage professional SAP assessment.

BBA – a recognised symbol of quality
BBA certification is recognised throughout the construction industry as a symbol of quality and reassurance. It’s a vital ingredient for product manufacturers to help ensure acceptance with specifiers, building control, local authorities and insurers. BBA work with the construction industry to achieve the approval of construction products through robust test and assessment schemes.
