2014 One of the first fully funded ECO schemes in London delivered by Keepmoat 
Value £550k

Residents from 350 properties in five high rise blocks now benefit from warmer homes as a result of the free cavity wall insulation works delivered by Avalon Sustainable Energy Solutions on behalf of Keepmoat. As one of the first fully funded ECO projects completed in London, it was entirely free of charge for residents, saving them on up to £140 per year on their energy bills. 

Accessing the blocks via rope instead of traditional scaffolding, we were able to increase efficiency whilst reducing disruption, enabling us to complete the works within a tight timescale and before winter. 

As a result of the works, the thermal insulation for the blocks has been greatly improved with each property receiving an individual energy performance certificate showing the increase in energy efficiency. For more information, click HERE.

2013 Utilising ECO funding from NPower

St Georges's Fields is a privately owned 1970s low-rise development located in a Westminster conservation area. The estate comprises of 300 privately owned flats. Completing the installation of works took just a few weeks and there was minimal disruption to residents. Using abseilers to install insulation negates the need for scaffolding, saving time, money and also reduces disruption and security risks for residents. NPower achieved a 5638 tonnes carbon saving. For more information, click HERE.

2012 Utilising CERT funding from British Gas 
Value £1.8m

Working directly with The London Borough of Southwark, Avalon Sustainable Energy Solutions delivered Cavity Wall Insulation to 2408 flats, across 59 tower blocks via rope access. Using our knowledge and experience, we helped the client identify the suitability of their high rise stock by sending our surveying team out free of charge to undertake a simple stock survey which could be used to identify a list of blocks that would benefit from CWI.

Once the list of suitable blocks were determined we then developed a project delivery program and instructed our in-house health and safety team to carry out site specific inspections that would enable them to produce appropriate method and risk assessments for each block.

This would determine not only the equipment required to rig and access each block but also key holder details, positioning of welfare facilities, parking and highlighting any possible risks to public or staff where restricted access is an issue, this document would also then be incorporated into daily tool-box briefings.

The project was delivered ahead of schedule and on budget without any incidents or accidents.

2011 Utilising CERT funding from British Gas 
Value £600k

As a sub-contractor appointed to work directly for City West Homes, Avalon Sustainable Energy Solutions tendered for a Cavity Wall Insulation project to install 920 flats with CWI measures. The buildings identified for inclusion were the most awkward to access for insulation. Because of this they had been placed into the second phase to enable City West Homes to achieve their Phase 1 targets.

Whilst access is not normally an issue for rope access technicians, the point of delivery of materials and access to the buildings is sometimes more complex requiring greater consideration of rigging points, working environment and the ability to physically deliver material to the site. However, using Avalon, City West Homes were able to undertake this project which was carried out successfully and ahead of program.

2010-2011 Utilising SHESP Funding 
Value £1.2m

Working through the Framework contractor Enterprise, Avalon Sustainable Energy Solutions successfully and on time installed Cavity Wall Insulation (CWI) measures to 2300 flats on behalf of City West Homes in Westminster, London.

Avalon assisted Enterprise with their bid for the works by sending out our experienced team of surveyors to inspect survey and ascertain the suitability of the stock for CWI and to look at the access requirements in order for Enterprise to submit the winning bid.

Using our abseil techniques to carry out the installs and minimising the access costs to the client meant that Enterprise were awarded the contract and the client getting approx. 50% more CWI works carried out rather than spending the budget on Mobile Elevated Work Platforms and scaffolding.

Our quick and easy approach to carrying out the works means that we could finish a 60 flat block in just over a week. Comparatively, it would probably take a week to arrange scaffold permits and get materials to site; and then take 3 weeks to erect. Another benefit is that no satellite dishes need to be taken down or moved for our works to take place.
