Peter and Maggie had lived in their 1970s detached house in Sandford-on-Thames since it was first built in 1972. Over the years, they’d made occasional updates – but they knew the house could be warmer, more energy-efficient, and better suited to the years ahead.

They wanted to cut carbon, reduce energy bills, and improve comfort – without the stress of navigating complex decisions on their own.

Why they turned to Cosy Homes Oxfordshire

Like many homeowners, Peter and Maggie had a clear idea of what they wanted to achieve – but weren’t sure where to begin. Faced with technical information and conflicting advice, they found the process overwhelming.

That changed when they got in touch with Cosy Homes Oxfordshire. Together, we created a tailored Whole House Plan, breaking everything down into clear, manageable steps that matched their goals, budget, and timeline.

“The Cosy Homes team is obviously dedicated, and we were particularly pleased with the project guidance – we would never have been able to cope with that.”

Smarter upgrades, one step at a time

Peter and Maggie took a phased approach to their retrofit, starting with the biggest impact measures and working through the rest in stages. This allowed them to spread out costs and make thoughtful decisions at every step.

The improvements they made included:

• Replacing their old oil-fired boiler with an Air Source Heat Pump, supported by a buffer vessel to store hot water
• Installing a Solar PV system on the sunniest part of their roof – generating their own electricity, with surplus used to heat water via an immersion
• Upgrading insulation throughout the home – including cavity wall, loft, and flat roof insulation
• Replacing one window to improve comfort and reduce heat loss

A plan that made progress possible

By working to a clear, expert-led plan, Peter and Maggie were able to move forward with confidence – knowing what their home needed, and in what order.

Rather than rushing into quick fixes, they made measured improvements that balanced energy savings with comfort and affordability. The result is a much warmer, more efficient home – and a smoother experience along the way.
