Improving home energy efficiency has never been more important for UK homeowners. With rising energy costs and growing environmental concerns, many households across Wokingham and the Thames Valley are looking for practical ways to cut bills while improving comfort.
One of our customers recently shared an inspiring local success story that shows how powerful the right home energy-efficiency improvements can be.

In 2023, our Wokingham-based customer began a series of home upgrades to reduce their energy consumption and lower household bills.
Their improvements included:

As part of their retrofit journey, they went far beyond surface-level improvements. They took time to fully understand:
This deeper knowledge allowed them not only to reduce their own energy bills, but also to help neighbours save hundreds of pounds each year through simple but effective changes.
After seeing the impact of their advice and being driven by a genuine passion for the environment, they went on to complete City & Guilds qualifications as Energy Advisors.
This led to the creation of KillaWatt, a local energy advice company helping homeowners across Wokingham and the surrounding areas improve efficiency and reduce costs.
KillaWatt’s home energy audits go far beyond a standard EPC. During an in-home visit, they assess:
Each visit is followed by a clear, easy-to-understand report outlining practical steps homeowners can take to improve comfort and reduce bills.
While EPCs can be useful for homebuyers, they often don’t address real-world issues like draughts, heating system optimisation, or day-to-day electricity usage.
Solar panels, batteries, and EV chargers can significantly reduce energy bills—but only if they’re set up correctly.
At Thames Valley Windows, we love seeing how high-quality windows, doors, and glazing can form the foundation of a broader home retrofit for energy efficiency.
Energy-efficient windows and doors don’t just reduce heat loss—they improve daily comfort, cut carbon emissions, and help households take control of their energy usage.
KillaWatt’s work complements this perfectly by helping homeowners understand and optimise every aspect of their home’s energy performance.
