Personal story:

I met Richard, a widower, in 2006. He wooed me with tales of climate change and cataclysmic disaster, and we married in 2011.

Glebe House, exactly half way between each of our homes, was for sale. My friend said: “I have seen the house you should buy, but it is very ugly”. It had the garden Richard wanted and the Wallingford town centre position I wanted.

We worked for over one and a half years (2013-2014), on renovations to make the house warmer and to improve the internal spaces. After suffering a rogue builder who fleeced us of massive amounts of cash, we had to learn a lot about building, to manage the project ourselves.

2015-16 we had the garden landscaped to protect us from the noise of the road, producing one pond for wildlife, and one pond for me to swim in. (The ducks do get muddled about this rule). Richard grows food in the garden, and the lawn is a wildflower meadow, with flowerbeds full of plants to encourage wildlife.

In the 2017, I stood for the Green Party in Wantage Constituency (a completely safe Tory seat). This gave me a platform to talk about our broken planning system, which is littering the countryside with unneeded carbon-hungry homes.


Richard was the director for climate change research at the Centre for Ecology and Hydrology. After I met him, I began a new career as a domestic energy efficiency advisor, running Ecomorph, within the construct of the ill-fated Green Deal.

We have joint concern for our ravaged planet, and wanted to renovate our house as a model ecofit of a 1960s house.

We transformed the house and garden, converting the loft into a large living space and re-arranging the interior. Insulation was the priority, and although the house already had filled cavity walls, we super-insulated with thorough loft insulation, and external wall cladding.

The ecofit was designed to reduce our carbon footprint dramatically, whilst increasing the comfort and the aesthetic of the house. Many people think it is a new house, due to the complete change in the facade from external wall insulation.

Property background:

This house was freezing! The windows upstairs were the originals: single-glazed, draughty windows with rotten wood frames. There was a strange dormer from the gigantic master bedroom, which flew over a patio space beneath. Its ‘cheeks’ were barely insulated.

There was minimal loft insulation, and an old boiler-room that infringed on the kitchen space and was a terrible heat-loss area, shining brightly red on the thermal camera.

Most miserable was the outdoor space. A back garden given over to featureless grass and a dying pear tree, with rubbish piled up in a corner. The grass had been used as a carpark, and the carport between the house and garage used as a throughway, for cars, and, as it turned out, for the howling gale and road-noises that rushed through it. The front garden was tarmac and useless earth mounds.

We got the keys to the house on a damp, mild November day in 2010 and promptly went on holiday. We returned to a frozen Wallingford, gradually defrosted the house, and went out for a couple of hours. On our return there was a monsoon in the kitchen. The mains feed to the coldwater tank had burst.

We camped out for 2 years in a patched-up home, planning refurbishments. One was definitely to convert the loft and replace the cold water tank with a mains-pressure cylinder on the ground floor where it could do less damage.

Key changes made:

  • Floor insulation including St Lucian’s Skirt
  • Roof room and flat roof insulation
  • Log burning stoves
  • Low energy lighting
  • PV to the east and west, now with batteries!
  • Roof insulation
  • Solar water heating
  • Triple Glazing
  • Water saving devices
  • Whole House Ventilation Heat Recovery system
  • Insulated doors
  • Rainwater harvesting
  • Natural swimming pond
  • Electric car charger
Measures installed in detail:

  • Roof room insulation – phenolics (eg Celotex) to rafters, backfilling with rockwool; u-values 0.1-0.2
  • Flat roof insulation with phenolics and rockwool ‘warm roof’, u-value 0.09
  • External wall insulation over filled cavity walls: 100mm Kingspan on outside; cost £25K, final wall u-value 0.17
  • Floor insulation where possible, and St Lucian’s Skirt of polystyrene around the perimeter; u-values 0.13-0.39
  • Triple Glazing Argon filled £23500, u=0.9 and insulated doors u=1.4.
  • Whole House Ventilation Heat Recovery System: wonderful!
  • Low energy LED lighting
  • Induction hob, and AAA rated electrical appliances
  • Two sets of PV, each of 4 kWp (16 panels), facing east and west
  • Batteries to store 4kWh of PV-generated electricity
  • Solar water heating using low-cost invention of Ed Atkinson
  • Log burning stoves in kitchen and living room
  • Condensing boiler: zoned heating and rads with TRVs
  • Rain water harvesting for toilets,outside taps,and washing machine
  • Water saving circulation pump to bring hot water across house, attachments to showers, replaced mains pipe
  • Natural swimming pool
  • Filtration pond to encourage wildlife
  • Gardening for biodiversity
  • Electric car charger
Benefits of work carried out:

The new layout has helped to open up the house, transforming the kitchen and loft space. The outside of the house is beautiful to look upon. Our winters are now warm and our summers cool thanks to proper insulation and ventilation.

I love the triple glazed windows which seal with a sucking in of breath, protecting us from the world outside. It has also greatly reduced road-noise.

Wildlife-friendly improvements to the garden give a feast to the eye with colourful flowers and fruits and an engaged insect population; bumble-bees rolling delightedly in the poppies.

Our electric car runs on free solar electricity for much of the year! The batteries smooth the energy from the in-out sunshine hitting the solar panels, and, with care, we can get a full charge without using grid electricity.

Favourite feature:

We have just installed batteries for the 8kWp of solar panels. This is such an exciting move forwards. Although they are only lead acid (we couldn’t afford lithium), they provide 4kWh of storage. This is enough to tide us over the summer nights, and also to smooth out usage during the day.

What I mean by that, is that if you put the washing machine on and then the sun goes behind a cloud, the batteries take over until the PV clocks back in again.

Project update:

Enjoying running the electric car, purely on solar energy at this time of year!
