Cavity wall installations drop since the Green Deal

Research suggests installations are 'down 60%'.

Energy efficiency graph

The number of cavity wall installations has dropped significantly since the Green Deal came into force, according to figures from the Cavity Insulation Guarantee Agency.

Only 1,138 installations were completed last month, down from 49,650 in April 2012, it says.

In the first four months of 2013 insulations of cavity walls averaged 11,000 a month – a fall of 73% on the 2013 monthly average. The Cavity Insulation Guarantee Agency monitors installations and guarantees.

Cavity wall insulation and the Green Deal 

This drop coincides with the changeover between government energy efficiency schemes. The previous government scheme  provided cavity wall and loft insulation either heavily subsidised or for free. The new Green Deal is a loan but currently only the assessments not the loans are available.

The Green Deal launched at the end of January this year and provides homeowners with a loan to install energy efficiency measures, such as insulation and double glazing.  

Alongside the Green Deal, the government has put the Energy Company Obligation (ECO) in place. Energy suppliers will use the ECO to subsidise energy saving measure. The money to fund the scheme will be taken from consumers’ energy bills. In order to qualify for a grant through the ECO scheme you have to meet certain criteria. You can find out if you qualify by calling the Energy Saving Advice Service on 0300 123 1234.

Which? and cavity wall insulation

Which? has previously said that it would like to see more of the ECO funding allocated to cavity wall and loft insulation because these are low cost ways of making savings on your energy bills. 

As it stands Which? thinks that too much of the ECO funding will subsidise high cost measures such as solid wall insulation.

Is the Green Deal good value for money?

Although the Green Deal is attached to a property, a lot depends on individual personal and financial circumstances and Green Deal plans will have different terms and conditions and interest rates.  

Which? advises you to read the terms carefully and think about the all the implications when signing up to this long term commitment. Read our Green Deal FAQs to find out more. 

Green Deal – shop around

As with any financial product, we recommend shopping around and researching whether or not the Green Deal is right for you. Remember:

  • You can get as many quotes as you want but check for charges. 
  • There are other means of paying for energy efficiency improvements, such as extending your mortgage. The best option will depend on your circumstances.
