Insurance regulations stipulate that air duct and ventilation systems should be cleaned on a regular basis. If this is not carried out, any fires with clear evidence that ventilation systems have not been cleaned and maintained can be voided.


No matter how well your ventilation and air conditioning works, dust and debris will accumulate in the ducts running through the building and become a breeding ground for bacteria and mould. Without regular cleaning, air will pass through the polluted duct carrying bacteria into the building.


The Workplace Regulations 1992 states it is every employer’s and building owner’s responsibility to ensure that the air introduced should be, as far as possible, free of any impurity that is likely to be offensive or cause ill health. It is the duty of the building owner or facilities manager to ensure the ventilation and / or air conditioning is internally clean and suitable records are maintained to support compliance.


Our complete ventilation duct cleaning service ensures the air system will be thoroughly cleaned from the supply system right through to the fresh air intake, mixing area and supply diffusers. Along with the grilles through to discharge to include, motors and fan blades.

On completion of the work we will provide a comprehensive Report, together with certification confirming the work has been undertaken. We can also include a detailed photographic portfolio, if required.

More and more we are seeing that failure to clean your system by a professional, accredited, kitchen extraction cleaning company is invalidating insurance policies. Fires caused by a lack of ventilation cleaning can result in costly situation for your business.

At Balmore Contracting, we promise to undertake cleaning at times convenient to you and do not charge extra fees for weekend or night work. Where access to the extraction system is not in place, and it is safe to do so, we install access panels ensuring thorough cleaning. On completion, we then provide a detailed Report and Schedule of Works, which is acceptable to environmental health inspections, fire regulations and insurance companies and is evidence to show you have taken action to reduce the fire risks from the build-up of grease in your extraction system.
