Personal story:

We have two young children and deeply care about the impact climate change will have  on future generations.  We are part time environmentalists offering environmental education to children,  it is called  Go Green Workshop.


Houses cause 33% of the pollution from CO2 so we wanted a home fit for the future of our children and the planet. We also want to show our home and the measures installed to other people who may be interested in saving energy and having substantially lower energy bills.

Property background:

When we bought our Edwardian home it was cold and draughty with single glazed windows and no insulation.  We wanted to retain all the original features like stained glass windows,  pine floors and double doors to the garden.

Key changes made:

Internal wall, floor and roof insulation, double glazed windows and install PV panels.

Full details of measures installed

Internal wall insulation: internal walls were fitted with 100mm cork thermal plaster internal wall insulation.

Floor insulation: The suspended timber floor was insulated with 200mm of wood fibre which was sandwiched between 2 layers of air tightness membrane.

Windows: The windows were replaced with timber frame sash double glazed windows, care was taken to ensure airtightness of the windows using specialised expanding foam and airtightness tape.

Roof insulation: The roof was insulated with 80mm of sheep wool between the rafters, the slanted ceilings were lined with 10mm of plasterboard laminated with Aerogel layer, the flat top floor ceiling was fitted with  300mm of sheeps wool.

The cellar was tanked to prevent rising damp and the walls were insulated with cork thermal plaster.

Double glazed the glass on the front door and draught proof around the inner front door.

5 chimneys have been blocked to stop cold air entering our home.

We use Ecotricity as our electricity and gas supplier which offer us 100% clean  gas and electricity, the electricity is produced from renewable energy.

Measures installed in detail:

10 cm of Internal solid wall insulation, 30cm of loft and 8cm of roof insulation, tanking and cellar wall insulation, 200m of floor insulation on the ground floor, all insulation using natural breathable materials which allows the moisture to pass through the house.

Sash timber double glazed windows with air tightness using expanding foam and airtightness tapes

PV panels on the south facing roof. LED lighting, A + rated kitchen appliances. Radiators have individual temperature control,  new combi boiler, humidistat bathroom extractor fans, 2 Passifer air vents  on each floor.

Benefits of work carried out:

We have saved £1500 pa off our annual heating bill, during the summer months we use hardly any electricity from the grid as we produce our own.

Favourite feature:

Double glazed French double doors onto the garden.
