“What’s not to like about Q-Bot, it’s safe, it’s non-disruptive, it makes people’s houses warmer and can save bills.”

“What’s not to like about Q-Bot, it’s safe, it’s non-disruptive, it makes people’s houses warmer and can save bills.”

Cllr Patricia Callaghan, Camden Council.

“Most importantly the tenants are comfortable and happy as it makes an immediate difference to their comfort as well as the energy cost. This is why we intend to look at how we can apply the treatment across our portfolio.”

Peter Armfield, CityWestHomes

“Using Q-Bot allowed us to bring our older homes to a higher standard with less disruption to our tenants than other insulation measures, and at a reasonable cost. Our assessment of the trials has been positive and we are looking at ways we can roll this out across more of our homes.”

John Kolm-Murray, Islington Council.

"We hope the robot will help us reduce disruption to residents, whilst allowing us to insulate their homes, keep them warm, and help to save them money on their energy bills."

Shaun Kelly, Peabody

“It’s very exciting that here in Cardiff we’re exploring new ways of saving energy that will not only be cost effective but will also potentially change the way organisations and individuals operate in the future.”

Cllr Ramesh Patel, Cardiff Council.

How can we help?

Q-Bot helps landlords reduce fuel poverty, increase the energy rating of their stock and improve comfort and wellbeing of their tenants. Floor insulation by Q-Bot typically improves the EPC score by 3-6 points (depending on the size of the property) and is the most cost-effective insulation measure after loft insulation.

Residents love Q-Bot for the efficient service, non-hassle installation and for making their home less draughty and a lot warmer.

Over 6 million homes in the UK are known as ‘hard to treat’ with standard energy efficiency measures. They are expensive to heat, suffer from cold draughts and are very uncomfortable. Q-Bot underfloor insulation reduces energy use by as much as 25% and draughts by up to 50%, all with minimal disruption to residents.

Reduce energy bills

Insulating a suspended timber floor can reduce the heating bills for a typical property by as much as quarter. Leeds Beckett University recently completed analysis of the heating bills before and after the installation of Q-Bot’s under floor insulation which showed a reduction in heating requirements of 26% and an improvement in air tightness of 39%.

Q-Bot studied several properties and found underfloor insulation typically saves around £180/year in heating bills. Examples for different properties are shown below and please see the Camden Council case study for further information.

Reduce fuel poverty

There is a direct link between fuel poverty and the EPC rating of a property (the EPC rating uses information on the building materials, construction and size along with assumptions on average comfort requirements to grade how efficient the property is on a scale from A - good to G - bad). Properties which are less energy efficient understandably have higher bills and have been shown to be at a greater risk of fuel poverty. Older, hard to treat properties tend to be some of the worst performing, but also the least frequently upgraded, as the options are expensive and have a huge range of practical issues.

Q-Bot makes homes warmer and easier to heat. As a result, it saves residents energy and money, making them better off. Q-Bot is also applicable to the worst performing, hard to treat properties, where there are few practical or cost-effective alternatives. The impact of Q-Bot’s insulation was studied in detail on a number of homes and it turns out that it is a lot more cost effective than alternative energy improvements such as solid wall insulation, double glazing or boiler replacement.

Camden Council
Camden Council have trialled the solution across 48 properties. The initial results show that the EPC ratings improved by an average of 6.1 points and energy bills were reduced by £181/year. The case study showed that Q-Bot’s solution is 2-4 times cheaper per EPC point than the alternative measures that are applicable to these properties.

Islington Council

The serious health impacts of cold homes led Islington Council to trial a ‘Warmth on Prescription’ programme aimed at improving the homes of those with serious health conditions. Traditional measures such as new boilers or loft insulation have been applied where possible, but alone do not bring a property up to modern standards. Therefore, many of these older, period properties remain energy inefficient, resulting in their inhabitants struggling to stay warm in winter.

A trial of Q-Bot’s under floor insulation service showed that this was the most cost-effective energy improvement option available (at £970 per EPC point compared to £2,015 for solid wall insulation and £11,810 when replacing the windows) with the biggest impact on CO2 reduction for the cost (with over 6.2kg of CO2 saved for each £1 spent over the lifetime of the measure, 4 times higher return than from installing a new condensing boiler).

Two Storey Terraced House

Location: North West London

Result: The SAP rating improved from 37F to 44E with predicted energy bill savings £150/year and a payback of 16 years.

Resident said, “I have definitely noticed a difference. The property retains the heat better, stays warm and is a lot less draughty now. I would recommend Q-Bot for floor insulation as disruption is limited.”

One Bedroom Bungalow

Location: Leeds

Result: Insulating the ground floor resulted in a 39% reduction in draughts following the installation and a 24% reduction in the energy required to heat the property.

The SAP rating improved from 59D to 64D with predicted energy bill savings £100/year.

Two Storey Semi Detached Cottage

Location: Hastings

Result: The SAP rating improved from 27F to 32F with predicted energy bill savings £150/year and a payback period of 18 years.

The resident was very pleased with the installation process, noting “This is the most friendly, helpful, informative, and accommodating team of workers I have ever experienced!”

Two Storey Terraced House

Location: Newcastle

Result:The SAP rating improved from 60D to 64D with predicted energy bill savings £90/year and a payback of 22 years.

Insulating the ground floor resulted in a 29% reduction in draughts for the whole property.

One Bedroom Purpose Built Flat

Location: North London

Result:Cold draughts breezing through the flat were reduced by 40%. The SAP rating improved from 58D to 65D with predicted energy bill savings £150/year and a payback of 20 years.

Resident commented “It has been great over this cold snap, it’s been much warmer and I’m spending less on heating. Friends no longer comment on my flat being freezing.”

Three Storey Semi-Detached House

Location: North London

Result:The SAP rating improved from 61D to 65D with predicted energy bill savings £255/year and a payback period of 16 years.

Resident noted “The work was done to plan; the installers were respectful, cleaned up each day and put the furniture back in place.”

Four Bedroom Purpose Built Flat

Result:The SAP rating improved from 58D to 70C with predicted energy bill savings £270/year and a payback period of 18 years.

Before the installation, the resident described crawling around to try and fill the gaps in the floor where the cold draughts were coming from. Following the install the resident stated the flat was “less draughty, warmer and no longer needs the heating on all the time.”

Two Storey Semi-Detached House
