Building Regulations 2013

What are the building regulations?

Other regulations to consider are the Code for Sustainable Homes and EPC for Construction.

New 2013 Building Regulations:

The new 2013 Building Regulations came into force on 6th April 2014.

Any sites registered before 5th April 2014 can still comply to 2010 building regulations. All sites registered after 6th April 2014 will have to comply to the new 2013 Regulations.

The Building Regulations are the Government’s minimum standards for design, construction and alterations to virtually every building.

The Building Regulations contain a list of requirements to ensure minimum standards for health, safety, welfare, convenience, energy efficiency and sustainability.

A key element of the Building Regulations for sustainable construction is the Part L. The aim of the Part L Regulation is to cut carbon emissions through savings in the energy needed to heat, cool, ventilate, light, and supply hot water to new buildings.

What's changed?


The minimum U-values for each part of the structure (or “backstops”) have stayed the same: * Roof 0.20W/m²K * Wall 0.30W/m²K * Floor 0.25W/m²K * Openings 2.0W/m²K


  • The new regulations for England require a 6% reduction in CO2 emissions for domestic buildings or 9% for commercial compared to 2010 Building Regulations.
  • Wales has differing regulations for the first time, from 31st July 2014, requiring a 8% reduction in CO2 emissions for domestic buildings compared to the 2010 regulations.


  • The Target Fabric Energy Efficiency (TFEE) is being introduced for new houses. This ensures developers must take a ‘Fabric First’ approach to new homes, and not compensate for less-than-average U-values by installing low carbon or renewable systems.
  • Only A-Rated boilers must be installed in new properties.
  • All new homes must have 100% Low Energy Lighting.

What is the SBS solution?

We have a series of technical drawings for brick and block construction to help house-builders cost-effectively achieve 2013 Building Regulations.

It is possible to achieve the new regulations simply and easily with standard masonry construction as long as you use strong fabric first principles, and have the right technical advice. Walls with a thickness of 300mm are still feasible with very little new additional equipment.

Should the build require renewable technologies we provide a simple menu of options to make the building as efficient as possible, and to cater for specific customer and site requirements


To ensure optimum whole-house performance we have specified a fabric-first approach.

Should the builder want to incorporate renewable technologies, we provide a simple menu of options to make the building as efficient as possible, and to cater for specific customer and site requirements.

How we have made a difference

Our Standard Construction drawings have been used by a number of national house builders to ensure their house types are compliant with the Building Regulations 2013. A top 50 house builder was able to build a more thermally efficient house, with lower running costs, and a 25mm reduction in cavity, whilst saving over £3,500 in materials per house.
