Gas Safety (Installation and Use) Regulations 1998
This piece of legislation is the most important rule regarding the installation of a new combi boiler. It covers what fittings need to be completed by a Gas Safe professional, including any work associated with installation, maintenance, or altering pipework, regulators or meters, or any other apparatuses or appliances that supply heat light or gas.
British Standards 7671 IET
Under British Standard guidelines, the IET (Institute of Engineering and Technology) outlines specific rules regarding any fitting or installation involving electricity. It is important to note that this does not apply to all combi boiler installations, as it is only about those with electrical components.
Part P of UK Building Regulations
Ensure you have an updated copy of this regulation, as the latest amendments came in 2010 (rather than the 2006 version). This is especially 
important if you are installing your new combi boiler without the assistance of a professional. The following regulations are merely recommendations for the most reasonable provisions against many kinds of danger (such as fire or physical injury) for combi boiler installers. The sub-categories are about a specific area of danger you may come across and are as follows:
1.Section A: Structure – concerns the strength and security of the building, specifically the areas where piping or wiring needs replacing or where who will install the combi boiler.
2.Section B: Fire Safety – ensures appropriate clothing and eye-wear are worn for installation, and caution is always taken when first lighting the new boiler.
3.Section C: Site Preparation – recommends clearing away clutter and moving out your family for a few days, if necessary, to ensure installation is completed with minimal fuss and disruption.
4. Section F: Ventilation – ensures the flue for your new combi boiler leads safely and securely outside to expel exhaust gases.
Remember, these are the most important rules and have been given only the most basic outline to help you begin.
For specific areas of concern, always look up the necessary laws and regulations in detail. If you still have reservations about your combi boiler installation, you can always get in contact with your Local Authority’s Building Control Department, who can provide free information and advice where necessary.
