Title: Ripon Cathedral
Value: £600k
Client: Ripon Cathedral
Description: Not every electrician gets to work in a Medieval Minster. Elliott Bennett (aged 18) is the apprentice working for R.T.Harris & Son Ltd, the contractors responsible for the Vision Project, the wiring and re-lighting work at Ripon Cathedral.

As part of this Heritage Lottery funded work, Elliott has been learning about working in a Grade 1 listed building: 'At first it was scary working up high, but with the harness it starts to feel safe. You have to pay attention to where you are drilling!' For this young Oxfordshire man, it is not only the first time working in a Cathedral, but also the first time working away from home. The contractors undertaking the work on Ripon Cathedral have experience in working on historic buildings. Mr Bob Harris, the MD, said: 'We put a very high value on training our people so that in this environment not only are they learning their electrical skills, but also developing an insight into the needs of historic buildings. Last year we worked on Salisbury Cathedral'. Elliott is seen here undertaking extra conservation training with the Cathedral Architect, Patrick Crawford, who said: 'As the Cathedral Architect I was delighted to have an opportunity to discuss with Elliott Bennett the extensive range of concerns which need to be addressed when working in a Historic Building of the significance of Ripon Cathedral. By training the next generation of craftsmen we are going a long way to ensuring that the fabric of these incredibly important buildings will be in safe hands for years to come'.

Title: St Antony's College, Hilda Besse Building, Dining Room
Value: £10K
Client: St Antony's College
Description: When an Oxford University college needed to improve comfort levels in a hard-to-heat dining hall, Dimplex’s commercial heating experts came up with an efficient solution to keep students warm year-round.


The dining hall at St Antony’s College was built in the late Sixties with large single-glazed windows, low levels of insulation and a high ceiling. The hall is used daily for lunch and dinner, and also frequently in the evening for a variety of other functions. It’s a large facility in the middle of the site, and an important focus in the students’ daily life, so it’s vital that it remains in commission.


The college consulted Oxford-based contractor RT Harris and Son with the aim of finding a more permanent and effective system. David Sexton explains: “Reliability was a priority in this installation, due to the frequent usage of this hall and high volumes of people depending on it. We use Dimplex products all the time, we know they won’t give any problems, so the manufacturer was our first choice."
