What visitors are saying

“This Milton Keynes Home World exhibition original (1982) eco home is quite an eye opener. The owners have added PV, zoning and a new boiler but the original building fabric still holds its own – beating current UK building regulations for energy efficiency!"

"The use of solar gain (large triple glazed windows to the south side) gives this bungalow great natural lighting and warmth. The underfloor heating and mechanical ventilation with heat recovery made it a very comfortable space on the (cold) day of our visit, despite the heating having switched off hours before our arrival.”

“Interesting to see which past eco measures were still effective and quality of original build etc, also how these were being upgraded with today's technology.”

“A fascinating tour of the Homeworld site, followed by a look round one of the houses. The owners were a mine of information and their enthusiasm was infectious.”

"Very interesting. Great hosts and very passionate about their house which really came across."

"My wife and I first saw these houses in 1982 which is why we were keen to revisit.”

Personal story:

I’m an architectural technician and both my wife Dianne and I are very keen to reduce energy use and carbon emissions. We had intended extending the house we were living in and had done a great deal of work making it a lot more energy efficient. However, we decided to view a couple of properties as a ‘possible’ alternative to extending our existing home. When we viewed the bungalow we felt that we needed to own it and restore it, making it as efficient as possible. We moved in at the end of September 2012 so it’s very much a ‘work in progress’. It’s a Danish, system build, timber framed design with brick and timber cladding and the lady who owned it before us had kept all the original brochures, including specifications and drawings. These state that the U-value for the walls when originally built was 0.23. Having done the calculations I think this is a bit optimistic and they were probably more like 0.3. Even so, it would pass current building regulations for energy performance; the house we sold to buy this one, which was built in 1994, would not.


The cost of energy will continue to rise so to spend money now to save money later (after we have both retired) seems an intelligent thing to do! I’m also keen to see how what was a ‘super home’ in 1981 can be a SuperHome 30 years later.

Property background:

Detached system built timber frame bungalow originally built in 1981 for the Milton Keynes Home World exhibition of 1982.

Key changes made:

  • MVHR (ITHO advance system) – the bungalow originally had a whole house ventilation system but this had been removed some years ago when it broke down, consequently the house was wringing with condensation and we’re gradually drying it out
  • Condensing ‘A’ rated gas fired boiler (Valliant ecotech plus 418)
  • Solar thermal (Solfex SSK 2.1 panel)
  • 4kWp solar PV (16 Conergy 250W panels)
  • With a new manifold installed, the existing underfloor heating system has been separated into 3 thermostatically controlled zones: all bedrooms in one zone, (as 3 out of 4 bedrooms have solar gain on south side). The lounge in another zone and the kitchen bathroom, shower room and the hall in the third which has no solar gain from the windows
  • Water saving devices: one 200 litre water butt – with another two waiting to be connect. Bathroom and showers will be modernised with aerated taps and shower head, also dual flush for the toilet cistern
  • 270mm loft insulation installed by previous owner. I’m going to add another layer on top as the last layer of mineral wood had to be moved to instal the duct work for the MVHR and other electrical work
  • Floor insulation installed from new with a U-value of 0.34 quoted

To date the total cost of all the changes is approximately £16,500. Existing double glazing is 24mm with two large windows triple glazed.

Measures installed in detail:

  • Loft and floor insulation
  • MVHR
  • Condensing ‘A’ rated gas boiler
  • Solar thermal
  • 4kWp solar PV
  • Underfloor heating zoning
  • Water saving devices: one 200 litre water butt
  • Triple Glazing was already in place

Superhomes are working closely with the Building Retrofit Network in Milton Keynes. This home was brought into the network with project support from Green Deal Pioneer Places Funding from DECC.

Benefits of work carried out:

Reducing energy bills and living in a warm, cosy home. We moved in at the end of September 2012 so, as yet, we have not lived in the house long enough to analyse the bills. We have monitors inside and outside the house recording the temperatures, we also note the consumption of electricity and gas.

Favourite feature:

Solar thermal panels to heat the hot water. At our last house we received a summer quarterly gas bill of under £5! Once you’ve had a solar thermal hot water system, you truly cannot understand why they are not fitted as ‘standard’ on all new homes!

Project update:

Since we last opened we have installed an “immersun” to convert the excess energy from our solar panels to heat hot water and a real-time solar monitor and have a growing spreadsheet showing energy use and cost against FIT and RHI income – and the water butts in the garden now number seven and are used in conjunction with solar pumps to make watering the garden easier!

Assessment types

SuperHomes Assessed

A home that has been visited and assessed by us and confirmed as reaching the SuperHome standard, which demonstrates a 60% carbon saving.

Homeowner Reported

Information has been provided by the homeowner about their home and energy use prior to the installation of measures and following their installation which demonstrates a carbon saving. This information has not been verified.

Remote Assessed

The homeowner has provided information on their home including what measures have been installed which has enables an assessor working on our behalf to assess their carbon savings. This home has not been visited to verify the measures installed.


This home has not been assessed, but the homeowner has reported what measures have been installed. It may be that this home is awaiting assessment.
