What visitors are saying

"Very motivating to hear pros and cons of different methods."

Personal story:

I am a retired lecturer in Further Education and moved to Leamington Spa when my late husband Christopher took up a post on the lecturing staff in the Engineering department at the University of Warwick in 1965.


My husband became involved with the Centre for Alternative Technology in Wales in 1975 and the whole family spent the summer there in 1976. In 1977 Christopher and Robert Todd (then Technical Director of the CAT) co-edited The Alternative Energy Strategy for the United Kingdom. 30 years later this was updated as Zero Carbon Britain and is now available to download on the web as Zero Carbon Britain.

On our return, Christopher was intent on making solar thermal panels, but sadly he died in early 1979 before he was able to finish these. As time moved on I was determined to put Christopher’s ideas and principles into practice. Being energy conscious was by then part of my make-up.

Property background:

The land was sold for building in 1896 so I assume the house was built soon after that.  It is a classic Victorian semi detached double fronted construction with 9 inch walls of Leamington bricks: fired just up Campion Road at the Leamington Brick Works (the Works chimney was taken down only a month or so after we moved in during August 1965).  This is now a Conservation Area.

In keeping with the needs of a Victorian House in a Conservation Area, much work has been done over the years to maintain the house in prime conservation condition. The original wooden frame windows have been kept and properly painted with the small amount of rotten wood removed and replaced with old wood scavenged from skips. Pointing has been done to a high standard on the brickwork as required to ensure that no damp can penetrate. The chimneys and firewalls have also been repointed, and four Victorian chimney pots installed where the originals had been removed, and 4 ‘ersatz’ pots now sit on the capped off gable end chimneys, which much improve the look of the house.

Key changes made:

I eventually got a solar thermal system installed by Solar Twin and began thinking about the next steps, eventually replacing the Solar Twin with solar tubes and installing PV panels on the gable end of the house. They caused quite a stir (which was the intention) and were there for three years, before being replaced by the ones on the main roof.

When I was redoing the kitchen all the internal walls got insulated and a conservatory (for solar gain) was built onto it. I put insulation in the loft then installed double glazing in about half of the windows in the house – the other half have good quality internal secondary glazing fitted to the original Victorian windows.

Measures installed in detail:

  • Condensing boiler
  • Approximately half of the windows have good quality secondary glazing
  • Some overhauled and draught stripped windows
  • Partial internal wall insulation
  • Low energy lighting
  • Full depth roof insulation
  • Photovoltaic panels on gable end
  • Solar thermal panels
  • Micro wind as part of Warwick Wind Trials
  • Wood burning stove
  • Conservatory for passive solar gain used in spring and autumn to heat the house


Benefits of work carried out:

The Solar PV provides the household with free electricity during the day and any surplus is exported to the grid.

The large Victorian style windows at the front of the house are made of plate glass which means the traffic noise from the road is not evident when the windows are closed.

Project update:

The wind Turbine is now gone because it was part of the Warwick Wind Trials which conclusively demonstrated that micro wind in urban areas Does Not Work!
