Despite months of preparing and chasing to get a Green Deal since March 2013, our actual Green Deal installation happened to coincide with my main PhD research in winter 2013/14. This meant I did not manage to blog about the process as we went along; but I did end up taking many pictures - often once the installer had left for the day and I returned from my fieldwork. It also meant that I missed out on being there for several crucial stages. For example it was my husband who was around when Instagroup came to inspect the works on two occasions; when the window cills were measured and installed and reveals insulated (only very few); when the insulation was mechanically fixed and gaps filled; the eaves capping was installed and I was also not present when the services were finally insulated and boxed in nor when the rendering and painting took place. 

Being unable to witness and influence the Green Deal installation process is definitely frustrating as an architect (and when knowing a thing or two about thermal bridging), though it probably prevented me from becoming the 'client from hell' by interfering. As such I do think that our experience and installation is probably fairly typical of a Green Deal installation and I will write another blog about some issues with standard detailing and trying to find solutions with the installer (who were as flexible as they could be within the constraints of Instagroup's EWI system and Green Deal approval). 

Actually, I bet you can identify some of these issues and (potential) problems from some of the photographs below, without my commentary? Do leave comments! 

The existing roof basically was just some asphalt on timber boards over timber joists. You can see here where the previous owner had the chimney removed and had run a new piece of asphalt across this gap! On the right is the new roof on top of the old: 18 mm OSB + vapour barrier + 100mm ECOTHERM insulation board (k=0.025 W/mK) + underlay + waterproofing. The new timber edge is to enable the 100 mm insulation and the roof also overhangs by ~ 150 mm over the wall to meet the 100 mm EWI at later stages, avoiding typical EWI Green Deal capping systems for most of the roof - see pictures. NB: We will still need to insulate in between the joists from the ceiling at some point,...

Our Green Deal process has finished exactly a year later - and we have just submitted paperwork for our cashback. 

Firstly, scaffold was installed in late November to enable flat roof insulation and new waterproofing, a process which took < 1 week. In early December, the scaffold was adjusted further away from the walls to allow for future EWI installation and things initially took off quickly. However, soon delays occurred due to darkness setting in sooner at that time of year and on many occasions the guys on site had to wait until temperatures were > 5ºC and rising to glue the insulation to the walls. As a result the works did not finish before Christmas and New Year 2013, and around this period much of the UK witnessed extreme weather leading to further delays on site: rendering and painting can only happen when there are several days of dry weather so there were several weeks where nothing could happen. A few Green Deal installers told me that they had been under pressure to render several houses to finish on time (before the cash-back ran out or ECO would be scrapped) and overnight rain washed the render away and it had to be all scraped off and redone at another time - so things could have been worse I guess!

Our window cills also took almost 2 months to arrive! 

NB: I will be taking some InfraRed images too and will post them here at some stage,...

The Sunday Times printed a brief 'quote' today of a much longer conversation (over 30 minutes + 2 follow-up emails) I had with their journalist Jonathan Leake on Friday 18th September. When the journalist called me, he said that most in industry he had spoken to said that the Green Deal has great potential but that in its present form it is too complex. I agreed with him. We discussed the process and I gave several examples of the complexity of the scheme, but I also said that DECC Green Deal team had been very helpful and got the ball rolling and that we now had quotes offering a large proportion of the works to be funded under ECO. Yet the final article ends up pretty negative about the Green Deal with no mention of the 'potential' of the Green Deal, nor its necessity. Below is the Sunday Times' 'quote': 

A lot has been made in the media and in politics that the Green Deal has not taken off and there are suggestions from some quarters that it should be scrapped. 

Readers of this blog will know about my own criticism and issues encountered with the Green Deal for my own house.

So far there are ’12 Green Deal Plans’, which I understand are the households currently having had their measures installed, but 677 were in the system since the end of August. This would exclude our GD plan and many others presumably. 

As time progresses, more plans will have been installed; but these numbers are still in stark contrast with the 71,000 GD assessments so far undertaken. Though this disjunct may be partially explained by the fact that the figures above do not include householders choosing to act outside the GD. 

More impressively however is that by the end of July there had been ~ 196,000 ECO measured installed, benefiting 173,000 households. Most of this was loft insulation(40%), cavity wall(34%) and boiler upgrades(21%) with just 4% solid wall insulation installations, as is illustrated in DECC's graph below. 

Reducing carbon emissions associated with domestic space heating is a key aspect to meet the UK Government’s overall emission reduction targets of 80% from 1990 levels by 2050 (Crown, 2008). Given that 7.8 million of 26.7 million dwellings in Great Britain are solid walled dwellings (DECC, 2012) and roughly 98% have un-insulated walls (DECC, 2012); the number of solid wall installations is particularly disappointing. 

To meet the ambitious carbon reduction targets set by Government in the Climate change Act, almost all such dwellings will need to be upgraded, yet while ploughing through literature, it struck me how little we actually know about the existing housing stock, and in particular pre-1919, solid walled dwellings. 

The STBA (May, 2012) highlight the lack of knowledge and the potential increased risk for unintended consequences to occur with damage to the building fabric, if we are not careful. Gauging from industry interest in my own PhD research on pre-1919 suspended timber ground floor heatloss and insulation measures, I am aware that industry will need answers much faster than the time it takes to collect evidence. 

Perhaps the slow green deal uptake is a blessing in disguise? Rather than rolling out measures on a large scale, there is the benefit of a slower uptake to learn lessons and for industry and academia to collect evidence of associated risks and how to minimise them.

This blog post is inspired by an email from Stewart Gilmour, CIBSE Director of finance and Services, quoting the Chief executive of the Green Deal Finance Company (GDFC) Mark Bayley who said the interest rate was very competitive already: “If you take a typical finance for a boiler over several years, you are looking at 19% and ours is less than 9%.”


Compared to the Bank of England base rate of 0.5%, 9% does not sound competitive at all, does it? In Germany, a similar 'pay as you save' scheme as the Green Deal was hugely successful with the energy-efficient improvement of about 1 million existing homes between 2006-2009. It achieved this with low interest (subsidised) loans and performance targeted subsidies (full report by UCL Energy Institute and LSE here). The interest rate was 3-5% fixed rate for ten years, and no early redemption penalties. 

Given the high quoted Green Deal interest rates and the difficulty to get a Green Deal Finance Plan, we decided to try to finance our GD interventions another way (i.e. part savings, part personal loan).  

We cannot remortgage before 2016 as we are in a fixed rate, so we cannot release 'cheap' money this way like some others can; nor does our bank offer a low interest rate loan for energy efficiency improvements, as offered by Nationwide at below 3% interest rate for existing mortgage holders.

Yet Bayley may not have been so incorrect stating that the 9% rate is "competitive". While many advertised bank loan rates are around 5-6% (assuming good credit; more like 14-15% with fair credit); the less money you borrow, the higher the interest rate. 

For example, if you do not hold a Nationwide mortgage and are borrowing with a standard personal loan instead;  < £5000 from Nationwide will attract 11.9% interest; while between £5000 and < £7500 this is 8.9% and the lower advertised rate of 4.9% does not kick in until you borrow > £7500. Most loans work this way. 

And these are quite good rates for small amounts of money, for example the Bank of Scotland's rate for < £5000 is as much as 19.5%; though the cheapest I could find for this amount was Zopa (peer to peer lending) with 6%. 

With personal loans, the payback is usually ≤ 5 years, while for the Green Deal this can be spread over a longer term, with a minimum of 10 years, ofcourse building up proportional interest accordingly (see later). 

As this is paid back through the energy bills, selling your house would in effect pay off 'your' loan, by passing it to the next homeowner with the house sale, unless you need to pay it off early to find a buyer; there are likely to be early repayment redemption penalties for GD loans. 

Example 6, courtesy of DECC*, below highlights that repaying £3900 over 25 years at an assumed interest rate of 7.9%, will result in a total cost to be paid back of around £9000, with £362 annual repayments, or around £30 per month. However, if you can afford a higher repayment of £85 per month, you are better off taking the Nationwide loan, even at nearly 12%, as you'd paid back a total of £5100 after 5 years for the initial borrowed £3900. 

So, is the 9% Green deal rate competitive? Depends how you look at it and what other access to money you have and how much you can afford to repay each month. It is indeed a good thing that there are other incentives to bring costs down for those on low incomes. As our Green Deal Assessor said at her visit: "you may find that borrowing under the Green Deal Finance Plan is not the best way to fund the improvements, so look around." This advice is sound, it seems!

An update is long overdue. In the past 12 weeks I have met with DECC and have had 3 installers over the floor (one of them 3 times even) and received one quote with an idea of ECO-funding available and am due to receive another this week. I will cover all of this in a separate blog update, hopefully early next week.

Firstly to keep you updated on my meeting with DECC:

The DECC Green Deal Team were genuinely interested in my experience as a consumer. I was impressed how the team knew the policy backward and forward and really took their time to listen and answer questions. They clearly have put a lot of work in.


The DECC team made it clear the GDAR is meant to be portable, but that some companies are taking a different approach to this and interpreting issues of liabilities differently. Linn Rafferty also discusses this here.

The DECC Green Deal team have kindly been in touch after spotting my tweets and blog. I have agreed to put feedback together from a GD occupant perspective and they have generously invited me to meet with them next week. (So any other occupants out there, feel free to contact me about the good and the bad) 

DECC stated that: " … we have been doing all we can to work with Green deal Providers to help them enter the market as quickly as possible. The Green Deal is a market based mechanism. Whilst Government is responsible for putting in place the legislative and supporting frameworks to enable delivery, we are reliant on the private sector to come forward and offer green deal assessments, Plans and measures to consumers."

The letter goes on to state that : "There are 48 companies registered as Green deal Providers and The Green Deal Finance Company stands ready to provide finance to them. Of these 48 companies, some are more advanced than others in terms of their own systems and readiness to deliver."

Of the 40 providers I contacted, around 55-60% responded. Of those who may offer individual households finance, they said that the software is not yet ready. 

The good news however is that DECC state that " .. we are aware that some companies are already offering ECO funding to support the option of solid wall insulation in individual households". This is good news, and DECC have - with my agreement- passed on my details to 2 companies, "who should be in touch shortly".

Interestingly, I have also been contacted by another occupant, who is trying to find a Green Deal installer with ECO access, (no need for finance) and he has been unable to find someone too. He works in the building industry so he has been trying to use his insider knowledge and contacts to negotiate and find willing 'ECO' installers. This process is obviously not repeatable for those outside the industry, and just adds to uptake barriers and hassle.

Finally, the DECC letter also says that ESAS (Energy saving advice Service 0300 123 1234) is:"...currently in the process of updating its advice to better reflect the status of different Providers and readiness to go to the market. ESAS is therefore the referral menchanism for those seeking a provider…". 

However, I did contact ESAS in April, before the DECC letter arrived and all they could do was take my details so DECC can give me a list of Providers who are ready as they do not have that list. They told me it would take 7-10 days to hear back with this information. So far, I have had more luck with direct DECC contact as I have not heard anything yet, though this is rather an unusual route and not really what I am meant to do. 

ESAS also told me (incorrectly) that all ECO-funding is means-tested and 
"only for people on certain benefits". When I read out a phrase from their own leaflet and Ofgem's website to contest this statement, ESAS then read out a standard statement stating the 3 parts of ECO (i.e. ECO Affordable Warmth; ECO Carbon Saving and ECO Carbon Saving Communities), to then agree that for ECO Carbon Saving, residents do not need to be on benefits to be eligible. Let's hope that this misinformation is due to early teething-problems, but I pointed out that it is crucial that ESAS give correct and consistent information to the consumer, particularly as in the information leaflet provided by the Green Deal Advisor it clearly directs consumers to them for advice on ECO-eligibility.

I have also received a request from DECC for feedback via an online survey ( and £10 voucher to encourage me to do so). It is a long and detailed survey, but  - if returned en masse by Green Deal occupants - will give insights to motivations for the Green Deal, assessment experience and identification of uptake barriers of approved measures. It is hoped that each occupant will fill this in as it will be useful feedback.
