Have you spoken to Building Control?

If you haven’t chosen your building control yet, our customers recommend Assent or London Building Control. You will need to know why an automatic fire suppression system is required in your home. Do you have a four-storey house, a three-story property with an open plan area, or another compliance requirement? If unsure, you can also speak to your builder, architect, or fire engineer. This is important as your installer needs this information to provide you with options to meet building regulations, as certain property types offer more flexibility than others.

What do you need to do?

Start by sending a floorplan of your property to your chosen installer, or ask for a site visit if preferred. They need a floorplan and the reason why you require a system to generate a quote and design proposal. You can show this to Building Control for pre-approval. That way, you can establish if your home will be compliant with Automist installed before you spend any money. Each design proposal will align with Plumis’ installation guidelines which consider how many sprayheads are needed in each room. Finally, why not set up a Building Passport to make it easy to hold and share all your building information.

Have trouble getting acceptance from Building Control?  

Perhaps they don’t like the layout of the building as it deviates from standard practice (guidance in Approved Document B)? You may need a fire engineering report to support your application. A fire engineer can help present your case, which is helpful for unusual projects. Perhaps they are unfamiliar with Automist and want you to use a traditional sprinkler? We can help and show them evidence why Automist is more suitable than traditional sprinklers for domestic fires. If all else fails, it is worth noting you can appeal for a ‘determination’ if you believe that your plans comply with regulations but have been rejected.

Your installation  

Once you have confirmation, book your installation with your Authorised Installer. Automist is designed for retrofit and to minimise disruption to your home. Once the installation is complete, your installer will provide you with the final sign-off paperwork. Remember to register your installation online. The manufacturer, Plumis, offers £50 John Lewis vouchers for those willing to share pictures and a short interview with us about their experience.
