On behalf of Longleat Building Services, we would very much like to thank Onyx Civils for the recent works completed at the Adventure Castle, and in the village of Horningsham.
The works were completed to a very high standard, and the projects managed from start to finish with expert care and attention to detail.
I would not hesitate to recommend Onyx Civils to anyone thinking of having and groundworks completed! Brilliant job, start to finish
Many thanks



Lewis Civil Engineering used Onyx Civils  on a pipeline project we have constructed for Wessex Water. As a company, we found that the services provided were to a high standard. This included excellent quality of work, time keeping, condition of plant, excellent attitude to work. Nothing that they were instructed to do was ever too much. Would strongly recommend their services

The projects Onyx Civils undertook for me have been carried out to a very high standard, on time and on budget. They are thorough, thoughtful and communicative and I recommend them to anyone looking for hard landscaping expertise.
