The UK government periodically offers schemes supporting home energy efficiency improvements. It’s worth checking the current status of the ECO4 scheme and the Great British Insulation Scheme, which may cover some window upgrades for eligible households. Get in touch with our team, and we’ll be happy to advise on what support may currently be available to you.

Yes, both financially and in terms of comfort. Beyond annual bill savings, well-fitted energy-efficient windows improve your property’s EPC rating, which can increase its market value. They also make your home noticeably warmer, quieter and less prone to condensation, improving the quality of life every day.

Key signs include condensation between the panes (indicating seal failure), cold draughts near closed windows, difficulty opening or closing, rattling frames, or windows that are simply single-glazed. If your windows are more than 20 years old, the energy performance will likely have deteriorated significantly.

Triple-glazed windows currently offer the highest level of thermal performance available for residential properties in the UK. They feature three panes of glass with two gas-filled cavities, achieving significantly lower U-values than double glazing. For most homes, A-rated double glazing is an excellent and cost-effective choice; triple glazing is ideal for those wanting maximum efficiency or living in particularly exposed locations.

The Energy Saving Trust estimates that upgrading from single glazing to A-rated double glazing can save a typical semi-detached home up to £235 per year. Even upgrading from older double glazing can result in meaningful savings, particularly if your current units show signs of seal failure or condensation between the panes.
