If you’re renovating a bathroom rather than installing one from scratch, utilities like electricity, plumbing, and waste will almost certainly be connected. However, you may require additional wiring or plumbing in your bathroom, or you may need to adjust the arrangement of your sanitaryware.
While changing worn-out sanitaryware and taps does not require building permit permission, moving or constructing a bathroom does.
Similarly, any electrical work in or around wet areas, such as bathtubs and showers, as well as any work that expands or modifies existing drainage systems, must comply with building regulations.
This is another area where hiring a professional builder can be beneficial in guiding you through the process. Many builders can find trustworthy tradesmen to complete electrical and plumbing work for you if you’re project managing.
When the task is finished, your employees should pass over the requisite certification, verifying that the work complies with building codes, if applicable. If you used qualified trades, this is a routine aspect of the operation. Remember, it’s your responsibility to keep your certifications secure and present them when needed—potential purchasers will want to see compliance documents if you’re selling your home.
