Why do we need Building Regulations?
Building Regulations are legal requirements aimed at achieving adequate standards for the construction of domestic, commercial and industrial buildings. They are laid down by Parliament and are supported by separate documents containing practical and technical guidance on compliance, which are known as 'Approved Documents'. These are produced in different parts.
Building Regulations have three purposes:
- To ensure the health and safety of people in and around buildings.
- The conservation of energy.
- Access to and facilities provided for all.

What are the Building Regulations? A summary of the 'Approved Documents'
The Approved Documents that run from Part A to Part P reproduce the legal requirements and give practical and technical guidance on how to meet them.
They are all summarised below. For more information please use the following link or alternatively contact us using the details found at the top of this web page.
Part A - Structural Safety
- The weight of the building from the walls, furniture and people in the building will be transmitted to the ground, so as not to cause instability to the building or other buildings.
- Requires buildings to be built in a way ensuring no collapse will occur disproportionate to its cause.
- Ground movement such as freezing of subsoil will not impair the stability of the building.
Part B - Fire Safety
- Requires safe means of escape from the building.
- Requires the stability of a building to be maintained in a fire, both internally and externally.
- Internally - The wall lining i.e. plaster, plasterboard or wooden boards on the walls and ceiling will resist the spread of flames and give off reasonable levels of heat, if on fire.
- Internal stability will be maintained during fire and fire spread will be prohibited.
- Fire and smoke will be prohibited from spreading to concealed spaces in a buildings structure.
- Externally - The external walls and roof will resist spread of fire to walls and roofs of other buildings.
- The building will be easily accessible for fire fighters and their equipment.
Part C - Site Preparation and Damp Proofing
- Nothing should be growing on the ground covered by the building.
- Precautions must be taken to stop gases and dangerous substances from previous land use from entering the building and endangering the health and safety of occupants.
- Subsoil drainage will be in place, if needed, to stop the passage of ground moisture to the interior of the building and to prevent damage to the fabric of the building.
- The walls, floors and roof of the building shall prevent moisture passing to the inside of the building.
- The building must have provision to prevent condensation occurring in the roof structure.
Part D - Toxic Substances
- Insulating materials inserted into cavity walls can give off fumes. Prevention must be taken to stop these fumes reaching occupants of the building.
Part E - Soundproofing
- Floors and walls between domestic buildings should have a certain resistance to the passage of sound.
- Sound insulation requirements also apply to floors and certain walls within individual dwellings and new schools.
Part F - Ventilation
- The building must have adequate provision for ventilation.
Part G - Hygiene
- Adequate sanitation facilities i.e. toilet.
- A house must have either a bath or shower with ability to heat hot water.
- Unvented hot water storage systems - restrictions apply to who can install the system.
Part H - Drainage and Waste Disposal
- An adequate system to carry water used for cooking, washing, toilet, bath or shower to a sewer, cesspool or settlement tank must be in place.
- A cesspool or settlement tank must be impermeable to liquids and have adequate ventilation. It must also have means of access for emptying, not harm the health of any person and not contaminate water or water supply.
- An adequate system to carry rainwater away from the roof of a building eg. guttering carrying water to a sewer.
- A place to put a wheelie bin or dustbin. The place must not harm anyone's health.
Part J - Heating Appliances
- Must have an adequate air supply for combustion and for efficient working of a fluepipe or chimney.
- Appliances shall discharge the products of combustion to the outside.
- The appliance, fireplace and chimney shall reduce the risk of the building catching fire.
Part K - Stairs, Ramps and Guards
- Stairs, ramps and ladders shall provide safety for people, when moving between different levels of a building.
- Stairs, ramps, floors and balconies shall be adequately guarded.
- Safety shall be provided for people using vehicle ramps and loading bays.
Part L - Conservation of Fuel and Power
- Provision must be made for the conservation of fuel and power in a building.
- The fabric of the building must limit heat loss.
- Controls for operating the heating of the building and heating of water.
- Heat loss from hot water tanks and hot water pipes must be limited.
- Lighting systems in buildings should use no more energy than needed and have adequate controls.
- New buildings to have thermal calculations provided to demonstrate their energy efficiency.
Part M - Access to and use of buildings
Buildings should have reasonable provision:
- For all people to gain access and use the building.
- Toilets provision shall be made available for all.
- If a building has seating such as audience or spectator seating, reasonable provision should be made for people with disabilities.
Part N - Glazing Materials and Protection
- Glazing that people come into contact with whilst in a building, should, if broken, break in a way unlikely to cause injury, resist impact without breaking or be shielded or protected from impact.
- Buildings, other than dwellings that have transparent glazing which people come into contact with while moving around a building, must have features to make it apparent. Windows that can be opened must be operated safely and provision made for safe accessible cleaning.
Part P - Electrical Safety
- Reasonable provision shall be made in the design, installation, inspection and testing of electrical installations in order to protect persons from fire or injury.
- Sufficient information shall be provided so that persons wishing to operate, maintain or alter an electrical installation can do so with reasonable safety.
- Installers who are members of a certified "Competent Persons Scheme" may carry out electrical work without the need to submit a formal building regulations application.
