Would fitting a combination boiler (including controls) in a bathroom cupboard be acceptable within Part L of regulations?
A. Part L does not introduce specific restrictions on where the boiler can be fitted. The bathroom must be considered along with all other locations if assessing the case for a non-condensing boiler – see Appendix A of the Domestic Heating Compliance guide. (This guide is referred to in the Approved Documents ADL1A and ADL1B). The Guide can be viewed or downloaded via the following link: http://www.planningportal.gov.uk/uploads/br/BR_PDF_PTL_NONDOMHEAT.pdf The boiler position must meet the requirements of manufacturers’ instructions, Building Regulations Parts J and P, the Gas Safety (Installation and Use) Regulations and relevant standards such as BS 5440. A particular consideration for bathroom installations is the electrical safety requirements in Part P. The installation of a boiler and controls in a bathroom cupboard is an accepted way of dealing with some of these more difficult requirements.
