Every business needs a backup power plan in case of emergency – and diesel generators are one of the most popular and reliable options. Having a reliable source of standby power can be really important for complying with industry regulations and requirements – but you also have to ensure that you follow noise laws and local council rules so that your generator set is legal and allowed to operate.
Here’s a quick and simple guide to generator regulations and noise laws so you know how to get the right essential critical power equipment to protect your business.
What are the noise laws for generators in the UK?
When it comes to getting started with critical power, one of the first questions you’ll need to ask is ‘do I need planning permission for a generator?’. As explained in our blog, under certain circumstances you might need planning permission to have a full generator set or Uninterruptible Power Supply installed on your site.
In the UK there are general noise regulations that will apply for the use of equipment, as well as specific regulations that control the use of generators in residential areas UK-wide.
How is noise measured?
For generators and critical power equipment, noise is measured in dB(A) – A-weighted decibels. When you purchase or hire a generator from Vital Power, you’ll get manufacturer’s information about the equipment’s dB(A) rating at a specific set distance. You can also get further information and advice from our expert generator engineers at every stage.
Silent generators usually operate at levels of around 75 to 85 dB(A) at a distance of 1 metre. For comparison, some other common equipment sound levels are:
- Normal conversation – 60-65 dB(A)
- Main road traffic at street level – 80 dB(A)
- Petrol lawn mower – 90 dB(A)
- Chainsaw – 110 dB(A)
What are the generator noise laws and UK regulations?
According to The Control of Noise at Work Regulations (2005) from the UK Government’s Health and Safety Executive, the sound level at which a business has to provide both hearing protection and zones for hearing protection is 85 dB(A). At a level of 80 dB(A), assessment into any risks to staff members’ health and training must be provided. There is also a named exposure limit of 87 dB(A). This means that after taking into account any provided hearing protection, workers cannot be exposed to noise over 87 dB(A).
How do I choose the right generator for my business?
Choosing the right generator will, of course, depend on the sound requirements of your business – for example if your staff will be working near the equipment, or if your site has lots of neighbours or is in a residential area. The choice will also be dictated by your site type, the power requirements of your equipment, and lots of other factors.
At Vital Power we stock a wide range of generator sets and equipment. As well as dedicated silent generators designed to operate at the quietest possible levels, we offer a selection of industrial generators for multiple sectors.
Our team of engineers work round the clock – with true 24-hour, 365-day service – to provide unbeatable service.
