The National Trust is the UK’s premier conservation organisation and has a membership of over 5 million people. As well as managing vast tracts of countryside, the Trust has a large portfolio of historic properties from the grand to the humble. Many of these are open to the public, and others are available as holiday rentals.

We’ve recently been commissioned to fit sympathetic secondary glazing to 25 National Trust rental properties in the Lake District over a period of 12 months. This builds on our longstanding relationship with the Trust that has seen us carry out work at a range of different properties, including the Manor House at Edenbridge and the iconic Lindisfarne Castle.

Lindisfarne Castle was a fantastic project. This North East landmark was first intended to defend the island from Scottish invaders when the relationship between England and Scotland was extremely volatile, but it now has an altogether more peaceful purpose. Fitting secondary glazing in this centuries-old structure had its challenges, needing to respond to both the aesthetic sensitivities of the site and the exposed, weather-battered location.

Our latest National Trust project will see horizontal sliding units being installed into historic casement windows. These are ideal in situations where ventilation is required and can be easily removed to allow for cleaning and maintenance of the primary windows.

The sliding units themselves are easy to maintain – something which is all-important in a historic holiday property where the maintenance and upkeep can be significant. The window units we will be fitting will improve thermal efficiency, ensuring the properties are cosy for visitors, even in the middle of winter. They will also reduce noise and meet the new EPC rules that come into force on the 1st of April.

We’re proud of our work alongside the chief custodian of the nation’s built heritage and environment, strengthening a relationship built on trust and delivery.
