Home Energy Efficiency Improvements in Wokingham: How One Retrofit Journey Led to Lower Bills for Hundreds

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.

A Retrofit Journey That Started with Energy-Efficient Windows

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

Their improvements included:

• Replacing all existing windows with high-performance uPVC energy-efficient windows
• Installing a composite traditional front door to reduce heat loss
• Fitting two Solarlux bifold door systems, combining modern design with excellent thermal performance
• These changes immediately improved insulation, reduced draughts, and helped stabilise indoor temperatures throughout the year.

Learning How Homes Really Use Energy

As part of their retrofit journey, they went far beyond surface-level improvements. They took time to fully understand:

• Home insulation performance
• Heating systems and boiler efficiency
• Solar panels and battery storage
• Energy tariffs and electricity usage patterns

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.

From Homeowner to Qualified Energy Advisor

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 Energy Efficiency Services

Comprehensive Home Energy Audits

KillaWatt’s home energy audits go far beyond a standard EPC. During an in-home visit, they assess:

• Inefficient energy use
• Heating system settings and controls
• Cold spots, draughts, and problem areas
• Damp or mould-prone zones
• Overall electricity consumption
• Whether a better energy tariff is available

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 System Reviews

Solar panels, batteries, and EV chargers can significantly reduce energy bills—but only if they’re set up correctly.

KillaWatt’s Solar System Reviews help homeowners understand:

• Whether their system is performing as expected
• How to maximise solar and battery usage
• How to optimise savings even during the winter months
• Common pitfalls that reduce returns on investment
• This service is ideal for homeowners who feel their solar system isn’t delivering the savings they expected.

Supporting Energy Efficient Homes Across the Thames Valley

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.
