Welcome to J Hare Diamond Drilling Ltd

JHare Diamond Drilling Ltd based in Hertfordshire was established in 1989 and has expanded to become one of the leading Diamond Drilling contractors in the UK.  

This expansion has been achieved through years of customer satisfaction, and by establishing close liaison at every level within Main Contractor organisations. We hold Term Order Contracts with a growing number of major UK construction companies, and are always keen to forge new working relationships within the construction industry.

Operating from our offices in Hitchin, Hertfordshire with a fleet of over 30 vehicles, we are ideally positioned to cover all of London and the Home Counties and have carried out contracts throughout mainland UK and abroad.  

Our base workforce of over 40 directly employed operators are all CSCS card registered, giving us a Platinum Commitment Award, and they all hold CITB Certificates of Safety Awareness and Certificates of Competence for the equipment they use. Our operators all hold NVQ level 2 in Specialist Concrete Occupations, and all have passed the Health & Safety touch screen test.

We are committed to an ongoing training programme of both in-house and specific external courses regarding safety and equipment for all our employees.  

All J Hare consumables conform to European Standard EN13236. We have recently achieved ISO14001 environmental compliancy, and are on course to achieve an IMS within 12 months, encompassing ISO9001, ISO18001 and ISO1400.1

Health and Safety is paramount to J Hare.  Our involvement with, and membership of the Drilling and Sawing Association (D.S.A.) keeps us up to date with new innovations and latest requirements in health and safety to ensure we remain at the forefront of our field.


Our safety record is excellent having never been issued with a prohibition or improvement notice, nor ever incurring any form of prosecution from the HSE.


Virtually all of our work is executed by utilising our comprehensive range of directly owned plant and equipment. Regular maintenance and PAT testing are carried out by our full time directly employed fitters.  

We are currently registered with Builders Profile, Competefor and Constructionline, Railtrack Achilles Link-up and CHAS, among others.
