Frequently Asked Questions

Below are a list of answers to frequently asked questions about each of our products. If your question isn’t answered in any of the below, feel free to contact us and we’ll be happy to help with your query.

Loft Insulation

Will I get Loft Insulation for free?

The funding we are able to secure for you to pay for your Loft Insulation varies with the level of Carbon Emission Savings achieved by having the work done. The survey you have done before installation predicts the expected carbon savings, a figure that varies on a home by home basis.

In some cases the survey will highlight that your funding entitlement will fall short of what is required for the work to be undertaken. Unfortunately this means that without a contribution from you to make up this shortfall we will be unable to proceed with your install as planned. That’s why we may have to ask for a contribution from you before the installation.

The payment will be due upon completion.

What is loft insulation?

Loft insulation is man-made mineral fibre in a roll form. Often referred to as “Quilt” the material generally used is made from silica sand, creating a wool-type product also known as glass wool. Old style loft insulation was known to be itchy, but modern insulation has been re-designed to be soft to touch and virtually non-itchy. Regardless though, it will be delivered into your loft sealed inside a plastic package.

How long does loft insulation last?

Providing the material is left undisturbed, it is maintenance free and should last indefinitely.

What arrangements are made for the installation?

A member of our production department will contact you to make a mutually convenient arrangement for the installation to be undertaken. Alternatively, you may telephone 0116 296 1402 and and a member of our team will schedule a mutually convenient appointment.

What happens to items stored within the loft space?

You must ensure that items stored within the loft space are removed prior to our crews arriving. Small items such as Christmas trees and suitcases will be moved within the loft by our crews, but our technicians are not able to move either general or large amounts of items.

Please ask if you are unsure.

Do I need to provide anything?

No, our installation teams provide all of their own equipment including lights and ladders.

What is the procedure regarding boarded areas?

Boarded areas will need to be removed prior to the date of installation. If you do not wish to remove the boarded area but wish to proceed with the installation, standard industry best practice is for the insulation to be laid over the boards.

How is loft insulation installed?

Our technician will arrive on the agreed date. The technician will be wearing our traditional red and blue BillSaveUK uniform, but we request that you remember to ask to see their identification.

The material will be in sealed bags, which will be carried into your loft and opened within the loft space. The insulation will be laid between and across the joists. The loft hatch will also be insulated. We must stress that once we have finished, the joists will not be visible and we recommend that you do not access the loft without the use of crawling boards and only still if you are aware of the exact position of the joists.

How long does it take to install loft insulation?

The installation should take between 1-2 hours to complete.

Is there much mess?

No. It is possible that a small amount of dust may fall from the loft hatch, (depending on how long it has been since the hatch was last opened!) but this will be cleared by the crew and all packaging will be removed from your home.

How much energy will I save by installing loft insulation?

You will save around 990kg of CO2 per year compared to an un-insulated loft, and around £240 per year on your energy bills.*

Cavity Wall Insulation

Will I get Cavity Wall Insulation for free?

The funding we are able to secure for you to pay for your Cavity Wall Insulation varies with the level of Carbon Emission Savings achieved by having the work done. The survey you have done before installation predicts the expected carbon savings, a figure that varies on a home by home basis.

In some cases the survey will highlight that your funding entitlement will fall short of what is required for the work to be undertaken. Unfortunately this means that without a contribution from you to make up this shortfall we will be unable to proceed with your install as planned. That’s why we may have to ask for a contribution from you before the installation.

The payment will be due upon completion.

Do I have to do anything before installation takes place?

The drilling process does create some vibration – so it would be wise to remove ornaments, particularly on external walls, for safety and peace of mind.

The technician will need to gain access to all walls, so he will need to get inside attached garages, lean-to-sheds, conservatories etc. If you have a wall right on a boundary, you may like to mention to your neighbour that the technician will need to go onto their property.

Does the technician have to come into the house?

The technician must undertake checks before and after installation, including any heating appliances, so it is essential that they have access inside the property.

Is there much mess?

The drilling process inevitably creates a little dust. The technician will go around the outside of your home at the end of the installation and clean up. It is important to note however, the conditions and nature of our weather can at times hamper even the most determined attempts.

Please, take the time to speak with our staff and be sure that you are happy with the finished product.

We also believe it wise to remove vehicles from the drive and items close to the walls. In return this will give the technician better access for equipment and tools.

How do I know the walls are full?

This system of cavity wall insulation has a defined pattern of holes, which has been tested by the British Board of Agrément to verify that it results in a complete fill.

Also, during your survey, we took measurements of your home including a depth gauge and inspection of the cavity to be filled. From these measurements we know the amount of material required to correctly fill your walls.

The technician will, therefore, check and record this data and match this against the quantity of insulation used. Our internal office staff operate a 100% check of this data and measure your results before we issue your 25 year guarantee.

It is possible that you may also be randomly selected in our on-site technical monitoring.

What about the ventilators that are in the external wall?

Ventilators supplying combustion air to fuel burning appliances must be safeguarded. Similarly ventilators at ground level that ventilate below timber floors must be safeguarded.

The technician will investigate them to check they are already sleeved. If they are not, the technician will remove them and seal around them to stop them being blocked by the insulation. Other vents, which may be redundant, such as cavity vents or vents that are in bedrooms may be closed off.

The technician should discuss these with you, so if you have any questions please ask.

Redundant airbricks may be filled.

What about filling the holes?

The technician will fill all the injection holes with mortar that closely matches the existing colour and texture.

On some older properties or weathered facades it may take several months for the newness of the mortar to blend, but these holes are very small and they will blend as the weather effects them.

On pebbledash finishes, they will apply pebbles to the surface to match the existing finish, as close as possible.

But my house has painted areas?

Normally, we will not paint the injection holes. Unfortunately, even if the original paint is used, it may not match due to weathering. So it may be necessary for you to consider painting the area, after the mortar has dried.

When will I receive the guarantee?

BillSaveUK will carry out the guarentee application on your behalf and issue you with the guarentee. Please note it can take up to 8 weeks for this to be delivered to you after installation.

Will my house be warmer?

Insulation dramatically reduces heat loss through the insulated wall therefore you will be able to achieve the same temperature in your home by turning your thermostat down by a little.

Your property should still achieve the desired warmth because the house will retain its temperature for longer.

It can also be noted that during the summer the insulated cavity will prevent some of the suns heat from entering the walls, therefore, keeping your home cooler.

Are there any maintenance or servicing requirements?

No, not to the cavity wall insulation, but normal building maintenance is needed.

If I am concerned after the installation – what should I do?

Talk to us to discuss your concerns and allow us an opportunity to investigate your worries. Most concerns can be resolved swiftly and efficiently so please do not hesitate to speak to a member of our customer services team.

How long will the insulation last?

For the life of the building – the British Board of Agrément say so.
