Thermal modernization = lower bills. When does insulation pay for itself?

Thermal modernization is a renovation that pays for itself — showing up as savings on your bills every month. ## How much you can save - Wall insulation (15–20 cm): 20–30% lower heating costs. - Window replacement: another 10–15%. - Roof insulation: 10–15% — heat escapes upwards the fastest. - Comprehensive: 40–50% lower annual bills. ## When it pays off For a 120 m² house, the investment is approximately £12,000–£18,000 with a 6–10 year payback period from savings alone. But that is not the whole story: - the house gains market value, - comfort increases — no more drafts or cold walls, - without thermal modernization, you cannot take advantage of subsidy programs. Start with an energy audit (£60–£120) — it will show which elements provide the highest return for your home. Compare quotes for thermal modernization — post your project on LocalTrader.
