Trickle vents and everything you need to know.

New building regulations have been announced in the UK today.


So, what is the new home regulation that has been placed today? From today, all new and replacement windows must meet new ventilation and energy efficiency regulations. What does that mean? New and replacement windows should be fitted with trickle vents regardless of whether the windows being replaced had vents in them or not if no background ventilation alternative is being installed.


What impact will trickle vents make?


Installing trickle vents to windows will help keep the air in our homes fresh and clean, as well as keep condensation out and lower humidity in a room. While they may not be the most comprehensive ventilation solution, they can be used in conjunction with other systems to ensure excellent air quality throughout your property.


What does the regulation require?


Here is a summary of what the regulation requires:


  • When replacing windows with background ventilation (or trickle vents), it is necessary to ensure that new trickle vents are no smaller than the vents in the original window, and they must be controllable either automatically or by the occupant.
  • When replacing windows without background ventilation (or trickle vents), replacement of the windows is likely to increase the home’s airtightness. Therefore, the regulations specify that the ventilation provision is no worse than before the work was carried out by ensuring the installation of appropriate trickle vents.


The installation of appropriate trickle vents involves careful assessment of the room that needs to be ventilated and the positioning of the vents within the building. This will ensure comfortable and adequate ventilation whilst managing draughts and external noise.


The new building regulations coming into effect from June also specify certain requirements for thermal efficiency – this means that a particular ‘U Value’ needs to be achieved:


  • Achieving a thermal efficiency U Value rating of 1.4 W/m²K or less is required for all new and replacement windows and doors.


These regulations are there to help improve air quality within our homes and reduce the chance of dampness. However, as some of you may be aware, they could also lead to a need to overheat your house in winter by a couple of degrees which goes against NZ50 ambitions.


Things for businesses and consumers to be aware of:

  1. Trickle vents are short in supply. They are a regulatory requirement so be prepared for secondary visits to fit, or a slight delay to your initial installation date.
  2. Trickle vents for some are not the prettiest item to see. For consumers, your contractor will be obligated to fit them, so we would expect them to be quite forthright in installing them.
  3. The majority of windows and doors projects will require them. There are a handful of scenarios where they may not be required. These kind be found in the document detailing Part F:

How to write a complaint properly?

Having an excellent customer experience is vital to us all. Whatever service you may require, the customer always looks at what lengths the service provider will go to make your journey easy and smooth. But what happens when you don’t get that service?

Just as important as it is to know how to handle a complaint, it’s also important to know how to write a valid complaint to those who have misled and not met your customer’s needs.

Here are our tips to help you achieve this:

Straight to the point

Writing a well-detailed complaint is the most important part in writing a complaint. You need to provide enough information to the person you’re writing to, enabling them to investigate your complaint properly. The aim is to stay on track and not go off point; going off-topic can be confusing, getting lost in translation and making things more complicated for your case.

100% Facts

When writing a complaint, one thing to bear in mind is that the truth will always come out. Keeping to the facts and what you know will be in your favour. Do not make allegations or accusations that you can not prove. Making fake accusations and allegations can lead to dismissing your complaint or something much more serious, which may cost you a more significant price.

Your feelings are valid

Making your feeling heard is an essential part of writing a complaint. Explain how you felt about the behaviour or service you’re complaining about, but don’t use emotive and abusive language. Reflecting on your feelings will help them understand how you felt about their service and how you weren’t pleased with the end results. Maintain a firm but respectful tone, and avoid aggressive, accusing language. Keep the tone of your complaint letter professional. The person dealing with you might not be directly responsible for the problem and will be more likely to help you if they sympathise with you.

Proof, proof and more proof

Proof is your best friend; having accurate information and proof of what happened on the day will help your complaint and speed up the process. Having the date, time, and who dealt with your service/products, documents, and email you’ve exchanged will make your complaint stronger to help your case to the fullest. If you don’t have the exact detail of the event, but know that it happened before a specific event, just say that. For example, you could say, ‘A few days before 14 February …’, or ‘Just before Christmas….’

Coming to a conclusion

What is it that you want? Is it your money back or the product to be replaced? Maybe an apology is enough.

Make it clear to tell them what you want from this situation. It’s important to voice the outcome you are after and say precisely what you expect from the person. That way, they are more likely to be able to resolve the problem faster and give you what you want.

Do not threaten action

Don’t threaten any action unless you are willing to follow through with it.

If you don’t have a strong case, or you are asking for perhaps more compensation than you think you might receive, or if the cost of the action is greater than the compensation, the other party will think that you are bluffing.

Take action only if it is worth it and only when all avenues of discussion have been exhausted.
