As manager of the team investigating complaints made to Brighton and Hove City Council about noisy neighbours, I would like to respond to "Life wrecked by no action on neighbours from Hell" (Opinion, April 20).

We receive about 3,000 noise complaints each year. We have a duty to investigate every complaint to establish if the problem warrants legal proceedings.

Initially, an informal approach is taken because, quite often, noise-makers may not be aware of the level of disturbance they are causing. We start by advising them a complaint has been received, while protecting the identity of the complainant.

If this proves unsuccessful, we attempt to gain evidence to determine if further legal action is required. The evidence must be sufficient to stand up in court if necessary.

Where we gain sufficient evidence, we are duty bound to take action. Equally, where, despite our efforts we have no or insufficient evidence, we cannot take legal action.

We have to work within the law. Where we are unable to gain evidence we can recommend either the individual takes private action or arbitrates with the neighbours through the Brighton and Hove Meditation Service.

I can assure the letter writer we take our responsibility seriously and do not "wash our hands of problems". When residents are not satisfied by our service, there are both internal and external avenues through which to pursue a complaint.
