Shrewsbury is known for its beautiful historical streets, timber-framed buildings, and elegant Georgian terraces. These distinctive homes give the town its unique charm and are a major reason why people choose to live here. For landlords, period properties can also be attractive investments. They often appeal to tenants looking for character homes with space, history and architectural details.
However, the same features that make these homes desirable can also make them challenging to modernise. With energy efficiency standards becoming a central focus in the private rented sector, many landlords are now asking how older properties will meet future expectations. The conversation around EPC requirements, particularly the goal of achieving EPC Band C, has become increasingly relevant in 2026.
For owners of buy-to-let Shrewsbury properties, the challenge is clear. How can landlords improve energy efficiency while preserving the character that makes these homes valuable in the first place? With careful planning and the right improvements, it is possible to balance both priorities.
Why energy efficiency matters for landlords
Energy efficiency is becoming an increasingly important part of housing policy across the UK. Government initiatives aim to improve the energy performance of homes, reduce carbon emissions and help tenants manage rising energy costs.
The Energy Performance Certificate, commonly known as an EPC, measures how efficiently a property uses energy. Ratings range from A, the most efficient, to G, the least efficient. Most rental properties currently require a minimum rating of E in order to be legally let.
However, proposed regulations suggest that higher standards may be expected in the future. Many discussions across the housing sector focus on the possibility of EPC Band C becoming the long-term benchmark for rental homes.
According to ONS housing energy efficiency data from 2026, older properties across the UK are more likely to fall into lower EPC categories. This is particularly relevant in historic towns such as Shrewsbury, where period homes form a large part of the housing stock.
Why period properties present unique challenges
Unlike modern homes, period properties were not designed with modern insulation standards in mind. Many traditional buildings use solid brick or stone walls rather than cavity walls, which means they lose heat more quickly.
Older windows, wooden floors and traditional ventilation methods also affect energy performance. While these features contribute to the property’s character, they can make achieving higher EPC ratings more complex.
In conservation areas, which are common in historic towns, there may also be restrictions on how properties can be altered. Landlords must therefore consider how improvements will affect the building’s appearance as well as its efficiency.
Start with a professional EPC assessment
Before planning any upgrades, landlords should review their current EPC report. This document provides detailed insight into how the property performs and identifies areas where improvements could be made.
The report also includes recommendations that may increase the EPC score. These suggestions often highlight practical improvements such as insulation upgrades or heating system improvements.
For landlords managing buy-to-let Shrewsbury properties, understanding the starting point is essential. Some homes may already be close to the desired EPC rating, meaning only a few targeted upgrades are required.
Improving insulation without damaging character
One of the most effective ways to improve energy efficiency in period homes is by enhancing insulation. However, because older buildings often rely on breathable materials, insulation must be installed carefully.
Loft insulation is usually one of the most straightforward upgrades. Adding insulation within the roof space can significantly reduce heat loss while leaving the property’s historic features untouched.
Floor insulation is another option. Many period homes have suspended timber floors that allow heat to escape. Insulating beneath these floors can improve warmth and comfort without affecting the appearance of the property.
These improvements can often be completed without major structural changes, making them a practical starting point for landlords.
Modern heating systems for older homes
Heating systems have a major influence on a property’s EPC rating. Older boilers tend to operate less efficiently than modern systems, meaning they consume more energy to produce the same level of heat.
Replacing an outdated boiler with a modern condensing system can significantly improve energy efficiency. Smart thermostats and programmable heating controls also allow tenants to manage heating more effectively.
These improvements benefit both landlords and tenants. Tenants enjoy a more comfortable living environment, while landlords see improved EPC ratings and potentially stronger rental demand.
Sensitive window upgrades
Windows are often a defining feature of period homes. Sash windows, in particular, are common in many historic Shrewsbury properties. While replacing these windows entirely may not be desirable, there are ways to improve their performance.
Secondary glazing is one popular solution. This involves installing an additional pane of glass on the interior side of the existing window. The original window remains intact, preserving the property’s appearance while improving insulation.
Draught-proofing sash windows is another effective improvement. By sealing gaps around frames and improving window fittings, landlords can reduce heat loss without altering the property’s character.
Managing ventilation carefully
Older properties rely on natural airflow to regulate moisture and maintain healthy living conditions. When improving insulation, it is important to ensure that ventilation remains adequate.
Poor ventilation can lead to condensation and damp problems. Landlords should therefore consider installing discreet ventilation solutions that maintain airflow while preserving energy efficiency.
Balanced ventilation systems or improved extractor fans in kitchens and bathrooms can help manage moisture effectively.
Balancing costs with return on investment
One of the biggest concerns landlords have about energy upgrades is the cost. Improving EPC ratings can require investment, and it is important to ensure that upgrades deliver value over time.
Focusing on improvements that provide the strongest return on investment can make the process more manageable. Upgrades such as insulation, efficient boilers and draught-proofing often provide significant energy savings relative to their cost.
Energy-efficient homes may also attract tenants more easily. Tenants increasingly consider energy bills when choosing a property, particularly as household costs continue to rise.
The importance of professional property management
Navigating energy efficiency improvements can be challenging without expert guidance. Landlords must balance regulatory requirements, building preservation and financial considerations.

Protecting the value of Shrewsbury’s heritage homes
Shrewsbury’s historic architecture is one of its greatest assets. Preserving these buildings while adapting them for modern living is essential for the long-term health of the local property market.
By upgrading energy performance carefully, landlords can protect the value of their properties while maintaining the charm that attracts tenants. Thoughtful improvements allow historic homes to remain comfortable, efficient and desirable.
Landlords who plan upgrades strategically are more likely to meet future standards without unnecessary expense.
Looking ahead to the future of buy-to-let in Shrewsbury
The conversation around EPC improvements will continue as housing standards evolve. While the prospect of new regulations can feel daunting, it also presents an opportunity for landlords to enhance their properties.
Energy-efficient homes are becoming increasingly attractive to tenants. By investing in thoughtful improvements, landlords can future-proof their portfolios while maintaining rental demand.
In historic towns like Shrewsbury, the goal is not to replace traditional homes with modern ones. Instead, it is about adapting heritage properties so they remain practical and comfortable in the years ahead.
