The new Hockerton type houses are coming on a pace in Eakring with the 4th out of 9 being plastered as I write. These houses will be the most well insulated in the UK SAP rating 142! The complement very well the “Hockerton House Performance Standard” (HHPS) that we have just trademarked. Please don’t be put off by this. They are free to download and use. We want as many more houses built to the highest standards as possible to help tackle the climate crises. We only ask that out name is referenced in any build project. The HHP standard goes well beyond any current option – the bar has been reset to meet the challenges we face. This contrasts with COP26 as we see below. The standard aims to help and guide you to achieve sustainable housing without fossil fuel input but with community at its heart. Available free of charge from our shop.

I am delighted to report that the eco house in Hockerton that we advertised sold and contracts have been exchanged; sorry if this was an opportunity that you wanted but missed. We had a lot of interest and could have sold the house many times over. It shows there is a market for eco houses that is not being met. The Guardian agrees.

We help make climate friendly housing a reality for people that come to us for help. Here is some resent feedback on our consultancy service.

Absolutely spot on info, thanks very much. You understood exactly what I was getting at with my questions. Just the right amount of detail at this stage for us. 

Intrigued to know why you changed your ventilation system fans to computer cooling fans – but that will do for another time. As you say, probably best to stick with a conventional system for now.

All the very best,


We offer guidance on your current home and new build consultancy service back up with full professional indemnity insurance.

I went to COP26 in Glasgow recently and was very heartened by the enormous numbers of people in the marches supporting action on the climate crises. I think these were under reported.

Does COP26 keep global warming below 2C?

Not all good news ….. According to Carbon Brief:

Not good enough! This all leads to mass extinctions and unparalleled climate shocks.

If we pull together at three levels, we have a chance to avert this catastrophe. Personnel actions, actions in our workplace and persuading the politicians to deliver policies that give us a chance. What can you do? Top tips to save the planet in order of priority:

Write to your MP, the person that represents you, to make the planet safe for you and future generations by removing all fossil fuel subsidies. We must leave fossil fuel in the ground!

Ask your boss what your workplace is doing to tackle the crises. Have they installed renewable energy yet?

Turning the heating down on the thermostat and then add insulation to your house.

Hockerton Housing Project is excited to announce it has released its own housing standard fit for the future world of zero carbon houses. It is called the Hockerton House Performance Standard and outlines the requirements that houses will need to be built to in order to achieve a sustainable low impact world. Unlike the Passivhaus standards these are free to use and go far beyond what Passivhaus can achieve. They are there to inspire!

Nick Raynsford MP launches HHP

Since the visit of the Minister for Housing Nick Raynsford at our opening we have been pushing the boundaries of construction. Our latest development of nine houses is taking shape with the walls going up in Howgate Close, Eakring with a predicted SAP score of 142! Jerry Harrall is delivery the project and writing Howgate Close, blog.


Eakering Howgate close foundations

Howgate close foundations

The UK is facing a crisis in housing which requires a dramatic change in how houses are designed and built to achieve the carbon reductions necessary to meet our climate change targets. With this in mind we are proposing standards of construction to inspire people to construct very high-performance houses factoring in embodied energy and within sustainable communities. The lifestyle of the people living in houses affects emissions of carbon significantly so cannot be ignored. A well-engineered house and designed community space will help inspire them to reduce their carbon emissions. Inspiration can lead to action given the right environment.

The imbedded House Performance Standards are performance based to allow individual designers and builders to create their own solutions. This should encourage creativity and enable future solutions to be incorporated in the finished houses.

These performance standards have been inspired by Dr Robert Vale, Professor Brenda Vale, Mr Nick Martin and the practical experience of the members of Hockerton Housing Project since 1993. They have drawn on General Information Report 53 produced for the Department of Environment Transport and the Regions by the Building Research Energy Conservation Support Unit. More recently the Leti “Net Zero Operational Carbon” targets have pushed us!

The Hockerton House Performance Standards

There are five subsidiary standards:

  1. Hockerton-Zero,
  2. Hockerton-Heat,
  3. Hockerton-Embodied
  4. Hockerton-Water,
  5. Hockerton-Community

Combining these five standards will create houses fit for the future.

How does HHP manage its autonomous water systems at this time of year? As spring arrives, we are planning ahead. We have been pumping rainwater up to our reservoir for the last few months. It is very nearly full at the moment which feels great. We could be going into a dry period so may need it to last quite a long time. We have over 150 days in the waterbody which means self-sufficient living does not feel risky. I am fairly sure it will rain again in the next 5 months!

How many rainwater harvesting systems do we have at HHP? We have three systems one using the reservoir which supplies the bulk of our water, a second one supplying our drinking water and a third more informal system catching water from a shed roof to help supplement watering the plants. Having diverse systems helps you become resilient.

Top Ten Tips for Rainwater Systems

The top ten ways I would suggest to improve a rainwater systems:

  1. Maintain the collection area so things like gutters are clear and clean. This means you will not lose water when it rains and your filters will have less work to do.
  2. Keep a record of when you change the filters so that you know when they are due to be done next time.
  3. Keep an inventory of the stock of filters so you are aware when you need to buy more.
  4. As mentioned above have more than one system so if one fails you have another water supply to hand.
  5. Regularly check the level of the store so you know how much water you have and adjust your behaviour should the tank become near empty.
  6. If you plan to have a drinking water system, consider using concrete tanks instead of plastic tanks for storage as these help reduce the acidity of the water, limit food for bacteria and improve the taste.
  7. Improve the resilience of your rainwater system by having a large storage tank. The amount you can store enables you to continue to use water between rainfall events. If you believe climate change is going to increase the variability of rainfall, then I would suggest you err on the side of caution and have as large a tank as possible. This will enable you to keep going for as long as possible with your own supply.
  8. If you want to collect rainwater on a budget, I suggest buying a device that you fit into a standard down pipe that collects the water without any leaves etc. The water collected can be diverted to something as simple as a dustbin or other watertight container. You will supply yourself with a surprising amount of water. There is a local supplier of off the shelf systems called Stormsaver if you want a whole house system.
  9. If you want to treat a large amount of water that is not for drinking, I suggest a slow sand filter. The name suggests it does not supply enough water but in fact they can. It all depends on the area of the sand and the depth of water above it.
  10. If you are using a slow sand filter to treat your water be attentive to th
    Rainwater system Slow Sand Filter at Hockerton Housing Project

    The water from out store is treated through this slow sand filter.

    e top 25 millimetres of sand. It is this where the Schmutsdeke lives that does most of the water treatment. When the flow rate reduces you will need to reduce the thickness of this layer but I would suggest only removing about 10 millimetres so there is sufficient left to continue treating the water to some extent when you refill the filter.

Our Rainwater Systems Products

If you want more information, we have chapter written on our water systems which has good clear information and advice. Get chapter 7 here. We also have one on our unique hot water systems chapter 4 and one on the value of autonomy, chapter 12,  which you may find useful.

People come on tours to see our systems and we get some good revues.

Subject: Today’s tour!

Dear Debbie, Matthew and Simon,

Thank you so much for the tour today. As always, it was a great way for the students to see and connect many different aspects of the material covered throughout their Environmental Management MSc, and a nice eye-opener for our international students, who are predominantly from India/Pakistan/East and West Africa (some of whom haven’t left their accommodation since they arrived in the UK in January!). Thanks, too for the added XR discussion. Hopefully, there’ll be a few more additions to the XR academy, now!

In other news, we’ve a new MSc course starting in September, on Renewable Energy Management. So it might mean even more attendees next time around, but perhaps by then we may be back in person.

All the best,


Book your tour here.

Rt Hon Robert Jenrick MP

House of Commons

Dear Robert Jenrick

I did not imagine I would be writing to you about a small piece of irreplaceable Fenland habitat near York and the threat from property developers to destroy it.  Understanding the value of our natural environment is key to a sustainable healthy future.

Globally our whole planet is under threat from Covid 19 and climate collapse.  Could the former be a turning point to help solve the latter? A cool-headed assessment is required. Thankfully, the World Meteorological Organisation (WMO) has just produced a report titled ‘The Global Climate 2015 to 2019’ to help us understand where we are. The New Scientist interviewed the author Petteri Taalas who had some very interesting things to say. 

  • During the past 20 years we have seen the 19 warmest years on record.
  • We have observed concentrations of carbon dioxide in the atmosphere of 415 parts per million (400 was once regarded as critical.)
  • During the past century sea level rise was typically 1 to 2 millimetres per year, during recent years we have seen the rise of between 4 and 5 millimetres per year.
  • 20 years ago we had 20 million people exposed to heat waves on an annual basis, during the past 3 years we have exceeded 200 million a year. We have seen casualties from this in Europe at over 75,000 people in a single year.

Where is all this leading? Is it possible that we will reach the lower limit of the Paris agreement, the international accord on limiting climate change, a 1.5-degree increase, during the coming five years – we typically see warming of 0.4 degrees per decade.

With these sobering conditions in mind as we invest in the recovery from COVID-19 it is imperative that we tackle climate change as part of the recovery. This is perfect opportunity to start solving the problem.

The IPCC report found last year that emissions must fall by 7.6% every year this decade to meet the Paris agreements goal of checking warming at 1.5 degrees Celsius. 

We cannot assume the climate catastrophe is solved by Covid -19. We must not head back to burning coal, oil and gas.  If we allow the climate catastrophe to continue the health and economic impacts will be much higher than the ones that we are facing with this “short term” COVID-19 crisis. If you compare casualties from hunger the numbers are already much higher than the COVID-19 casualties.

Please support The Climate and Ecological Emergency Bill – this new Bill is coming to the house of commons soon!

Details here for the CEE. What it aims to achieve:

What about the little scrap of fenland bog in Askham near York? Well I am pleased to say you made the right decision and stopped the development. I wholeheartedly congratulate you for this. Please focus your mind on solving the much bigger yet more important problem of the climate crisis with similar resolve. You would be very welcome to visit Hockerton Housing Project to see our attempt at a solution for low cost low impact eco housing with a holistic approach while still meeting very high environmental, social and financial standards.

If you have read to here congratulations. If you have read to here and you are not Robert Jenrick please consider sending this or a similar letter to your MP. If you are an MP please consider acting upon this information.


If you want to come to see Hockerton Housing Project for real book a place here for the 12th September.

May be of interest….a webinar run by The Concrete Centre provides an introduction to thermal mass and its energy/carbon saving benefits. It will cover: What is thermal mass? How is it used? How is it measured and how much do you need? General rules of thumb are provided throughout the talk, including the upfront carbon savings that can be achieved through avoided internal finishes and M&E plant. Book now
