F G Alden Ltd Special Projects Department is experienced at carrying out a wide range of small to medium sized mechanical services projects.

Our main area of work within special projects, is where our experienced staff can design a plant room to suit our customer’s particular requirements, whether as a replacement/ refurbishment or new installation. Most of our Special Projects works are carried out in existing buildings.


The majority of our workforce have been with the company for many years and stand by the same philosophies of quality and value upon which the reputation of the business was originally founded.


Founded in the early 1920’s, Aldens have become the most substantial and highly regarded mechanical engineering company in Oxfordshire.

We have been awarded the Royal Warrant of Appointment to the Queen for our work on behalf of the Royal household, in particular the fire restoration works at Windsor Castle.

The firm was established in 1923 and the business first operated from High Street, Oxford before moving in 1925 to New Road. Following from New Road, we then moved to Aristotle Lane in 1961 and again in 2000 to where we are currently located in Langford Locks, Kidlington.

Throughout the 1930’s Alden’s made great strides in the area of air conditioning as well as central heating, “environmental engineering” as it became known.

At the outbreak of the war in 1939, Alden’s became heavily involved in Britain’s war effort, turning over the workforce to the needs of the nation.
Following the war, Alden’s experience with the Universities paid great dividends. The Government’s interest in education meant that this became a considerable growth area for the company.

During the 1950’s many contracts were carried for the Government, and the refurbishment of the London Guildhall.
The new prosperity of the 60’s brought contracts in the commercial sector, particularly office blocks and retail outlets.

In the 70’s and early 80’s the company was very much involved in the Hospital expansion programme. The 1990’s included work within the Pharmaceutical research and manufacturing industry.
Since entering the 21st century we are proud to have been associated with many prestigious projects including the Said Business School, Tusmore House, Kensington Palace and most recently Lords Pavilion, amongst many others.

We work closely with many leading firms of Architects and Consulting Engineers, and over the years we have also worked extremely successfully in a consortium with other building disciplines.
