Energy costs remain a business risk
Energy costs have become one of the most important operating risks for commercial buildings. Although average non-domestic energy prices have eased from the extreme levels seen during the energy crisis, they remain significantly higher than they were in 2021.
The Office for National Statistics reported that the average electricity price for UK non-domestic users increased from 14.81 pence per kWh in Q1 2021 to a peak of 28.39 pence per kWh in Q4 2023 — a rise of more than 90%.
The DESNZ Quarterly Energy Prices release showed average non-domestic electricity prices including Climate Change Levy at 24.14 pence per kWh in Q1 2026, with gas at 5.17 pence per kWh.
Why glazing upgrades can be a strategic decision
Historically, many glass replacement projects were treated as simple repairs. A unit failed, glass cracked, condensation appeared between the panes, or a building needed to be made safe.
Today, glass replacement can be far more strategic.
Modern glazing can be selected to improve thermal insulation, reduce solar gain, improve internal comfort and modernise the appearance of the façade. In some cases, the existing window or curtain walling system may still be suitable, meaning the glass can be upgraded without replacing the entire façade.
This can make glazing upgrades a practical part of a wider building improvement strategy, particularly for offices, schools, healthcare buildings, leisure centres, retail premises and public buildings.
The risk of delaying essential upgrades
When budgets are tight, it can be tempting to delay building upgrades. But delay can carry its own risks.
Old or failed glazing may continue to perform poorly. Internal spaces may remain too hot in summer or too cold in winter. Tenants and building users may continue to complain about comfort. Heating and cooling systems may keep working harder than necessary.
A delayed glazing upgrade can also mean that a building owner continues to carry exposure to energy price volatility. The building may not be using energy as efficiently as it could, and the opportunity to improve performance is pushed further into the future.

Why spreading the cost can reduce risk
For many commercial customers, the main benefit of finance is not simply affordability. It is control.
By spreading the cost of a glazing upgrade over an agreed period, a customer may be able to preserve cash reserves, avoid a large one-off capital outlay and plan repayments alongside other operating costs.
The British Business Bank explains that asset finance can help a business acquire business-critical assets, replace ageing equipment or expand operations without putting additional pressure on cashflow or needing to raise a significant amount of working capital before purchase.
For a glazing upgrade, this can be particularly relevant. The building owner may be investing in a long-life improvement to the building envelope. Spreading the cost over time can help match the project cost more closely to the period over which the building may benefit from improved appearance, comfort and performance.
Use the Dortech calculator first — then explore finance
Before considering finance, customers should first understand the potential value of the glazing upgrade itself.
Dortech Maintenance’s Commercial Glazing Energy-Saving Model has been created to help customers explore the possible impact of upgrading commercial glass. The calculator helps users consider how changes in glazing specification may influence heat loss, solar gain and indicative energy-saving potential.
Once a customer has used the Dortech calculator to understand the potential performance benefits, the next step is to consider how the project could be funded.
The embedded HEXA Finance calculator on the Dortech Maintenance page allows customers to explore what their glazing upgrade project could cost if financed over time. This gives building owners, landlords and facilities managers a clearer view of possible monthly payments before making a decision.
A smarter way to plan glass replacement
In a high-energy-cost environment, commercial glass replacement should not always be treated as a distress purchase or emergency repair.
It can be part of a planned building improvement strategy.
By combining Dortech Maintenance’s glazing expertise, the Glass Energy Saving Calculator and access to project finance through HEXA Finance, customers can make more informed decisions about their buildings.
They can explore the potential benefits, understand the likely project cost, consider whether finance is suitable and decide whether upgrading their glazing could support better comfort, better appearance and improved energy performance.
