We moved to Leicester from Bedfordshire in 2009 with Rick’s new job, which was as a university lecturer in energy and sustainable development. We rented a house with the intention of getting to know the area and finding a house that needed renovating so that we could experience an eco-retrofit for ourselves. We are both keen DIYers so we felt that we could tackle much of the work ourselves. We found an empty house in need of renovation, since it had not been updated at all since it was built in 1978. Our children were adults and we felt we had the time and resources to renovate the house. We bought the house in January 2010 but decided not to move in until we had completed much of the noisy and dirty work, which we did while we were renting. This included installing the new central heating system, boiler, underfloor heating, wood burning stove, kitchen, bathroom and associated plumbing, downstairs flooring, an almost complete re-wire and carpets upstairs. We decorated each room quite speedily in magnolia, reasoning that we’d do each room properly when we had lived there a while and had time to choose the colours properly. We moved into the house in April 2010 with many jobs still to do.
The next jobs we tackled were the downstairs toilet and we also completed the bathroom, kitchen and utility room and fitted a water softener. We also had the loft insulation increased to modern standards and had double-glazed windows and doors installed. We went for wooden windows at the front since we feel these suited the house this age. These windows were made by a local company with turned out to be the same company who had made the original 1978 window frames! So cut costs, we had uPVC windows installed at the back and sides and a uPVC back door.
We then tackled the en-suite bathroom by replacing the old bright purple toilet, bidet, sink and shower with modern units in white including a dual-flush toilet to save water. At this stage we insulated the space between the garage and the en-suite and also added fire-proof plasterboard in the garage.
Next we had solar thermal panels installed to feed the hot water cylinder (we had previously chosen a cylinder with two heating coils that was compatible with solar hot water heating). While the scaffolding was up, we used it to install the first of two sun-tubes. Since these are quite expensive we wanted to see whether we could get away with one instead of two.
After a year of living with solar hot water we were so pleased that we decided to use the rest of the roof for a PV installation. The reason we had not done this earlier was that we felt the house was unsuitable with its east/west facing roof, but when Rick had learned how to estimate the energy gain we changed our minds. We installed a 4kWp PV system with 10 panels on the back of the house and 4 on the front. While the scaffolding was up, we took the opportunity to install a second sun tube.
Since then, there have mainly been small modifications such as water butts, extra LED lights, a garden pond and a wood store. We now have an electric vehicle (Vauxhall Ampera) and have installed a charge point. During the week, the car is mainly used by Shirley who finds the battery range is more than adequate for commuting even in winter, while Rick usually cycles to work.
Our daughter has left home but loves coming to stay partly because the house is very cosy, especially in winter. Our son is living with us having recently completed a degree in the city and his girlfriend stays occasionally.
To reduce our environmental impact, save money and experience a range of retrofittable energy efficiency upgrades to see which work best for us and which might be worth avoiding in future.
A 1978 detached home with a double garage and a small garden to the rear. It was built by local builders and is one of three in the village of Great Glen. It had cavity wall insulation and rudimentary loft insulation when we bought it, but it also had single glazing throughout and a very inefficient boiler. One reason that we bought the house was that although it had a gas fire (that did not work) it has a chimney that looked as if it contained a flue that was suitable for a wood burner. When we moved in, it turned out to be ideal so that was one of the first jobs we tackled.
Significantly reduced CO2 emissions and energy costs, although we did not live in the house before the refurb so this is impossible to verify. We believe the PV will have paid back over 9 years but the solar thermal panels will take much longer to pay back. Sun tubes have really improved what was a gloomy upstairs corridor but savings are negligible. Improved comfort from underfloor heating, mains pressure shower and woodburner (which is also mesmerising to look at and can be used to roast chestnuts).
Wood burning stove, due to the combination of comfort, low cost, visual appeal and ‘carbon neutrality’. The shower is a close second and underfloor heating third, both for comfort reasons.
