Home energy

A warmer home that uses less energy.

The best retrofit is rarely one magic technology. It is a sequence: understand the building, stop wasting heat, improve comfort and ventilation, then choose low-carbon heating and generation that suit the home.

Start with the building

Woodstock has everything from modern estates to old stone cottages, listed buildings and homes in the conservation area. The right measures depend on how a particular building was constructed, how it is heated and ventilated, and what problems you are trying to solve.

For substantial work, a whole-house plan can prevent expensive mistakes: for example, fitting a new heating system before reducing heat loss, or adding insulation without thinking about moisture and ventilation.

1 · Understand

Look at bills, comfort problems, draughts, damp, ventilation and the fabric of the home. Thermal imaging in cold weather can help reveal heat-loss patterns, but it is most useful when interpreted in context.

2 · Reduce demand

Draught-proofing, loft insulation, appropriate wall or floor insulation and better windows or secondary glazing can all reduce the amount of heat a home needs. In older buildings, materials and moisture movement matter.

3 · Control heat well

Good thermostatic controls, sensible heating schedules and well-balanced radiators are unglamorous but effective. They can improve comfort without major building work.

4 · Decarbonise heating

Heat pumps can provide efficient low-carbon heating when correctly designed for the property. The installer should assess heat loss, emitters, hot-water needs and electrical capacity rather than simply replace a boiler like-for-like.

5 · Generate electricity

Roof-mounted solar PV can cut grid electricity use and export surplus power. Batteries may increase self-use, but the economics depend on your generation, consumption and tariff.

Solar generation can complement efficiency and low-carbon heating; reducing demand first usually makes every later step work better.

Where to get independent help

Cosy Homes Oxfordshire offers independent whole-home retrofit advice and can help residents work out which improvements make sense and in what order. It is particularly useful when a house needs more than a single straightforward measure.

Energy Saving Trust provides current national guidance on insulation, heat pumps, solar, grants and consumer choices. Funding changes, so it is worth checking current eligibility before planning around a grant.

Funding changes over timeAs checked in September 2026, the Boiler Upgrade Scheme can provide up to £7,500 towards eligible low-carbon heating systems, with temporary higher support for some off-gas-grid homes. Always check the current scheme rules before committing to work.

What Sustainable Woodstock has done locally

Home energy has been part of Sustainable Woodstock's work for many years. Volunteers have organised thermal-imaging surveys to help residents understand where heat was escaping and previously coordinated group purchasing of solar PV to make installations easier and more affordable.

The technology and funding landscape has changed since those early projects, but the underlying idea has not: good information, trusted local experience and collective action can make difficult household decisions easier.

Have useful local experience? If you have recently insulated an older Woodstock home, installed a heat pump or solar PV, or navigated listed-building and conservation-area constraints, your experience could help other residents. Sustainable Woodstock is interested in sharing practical local learning rather than promoting particular suppliers.

A sensible order of questions

  • Where is the home losing heat, and what makes rooms uncomfortable?
  • Which low-cost draught and control improvements are worth doing immediately?
  • Which insulation measures are appropriate for this building fabric?
  • How will ventilation and moisture be managed after improvements?
  • What size heating system will the improved home actually need?
  • Would solar PV or a battery fit the household's electricity use?
  • Are current grants or local support available?
