Alan Dadley,
Managing Director


With over 40 years in the security industry and having diversified into fire protection some 20 years ago, Alan’s background gives Davenheath a strong focus on the industry.  Alan’s previous security business merged with Davenheath in 2002 giving Davenheath a broader service to customers.

Running the business doesn’t leave much time for recreation but when the opportunity arises Alan is a real film buff converting his loft into a home cinema.

Sue Gregory,

With strong administration and financial skills, Sue joined Davenheath in 2005 after having run her own business successfully for many years.  Having been involved with Davenheath prior to joining she knew the business well and very soon became a significant key member of the team accepting a directorship in 2007.

Apart from organising the team she organises her home around her family and 3 dogs as well as the odd bit of DIY.


Charlotte Dadley,
Office Manager

As you guessed from the name, Charlotte is Alan’s daughter.  Charlotte joined Davenheath in May 2011 booking work in for the engineers.  With an inquisitive mind and the need to always be busy, she quickly progressed to managing the company vehicles and IT requirements and finally to book keeping.  Deciding to have a short break of service to broaden her new found skills with numbers, she again returned to the fold in August 2016 as Office Manager overseeing all that she had carried out before and managing key accounts of the business.

Charlotte loves a glass of Prosecco which we attribute to her ‘sparkling’ nature and a good holiday as long as her dad looks after her cats.


Matt’s best quote though is  ‘Born to fish, forced to work’

Matt Gregory,
Design Engineer

From working at Davenheath during his school holidays Matt joined the company straight from school as an apprentice fire alarm engineer whilst attending college to gain his electrical qualifications.  Never having looked back he has progressed through the ranks of servicing, installing, fault finding and 10 years on he is now one of our Design Engineers getting to grips with paperwork.

Dan Henry,
Design Engineer

In November 2011 Dan Henry decided Davenheath was a company where he would like to work.  With fatherhood looming he saw prospects for a good future within the company.  However due to a severe injury in 2012 Dan was unable to return to work for over a year, unperturbed his career has progressed seeing him move to commissioning of systems and in depth fault finding to design engineer.


All that and 3 children later you would think Dan had no time for recreation…..you would be wrong.  As a very avid follower of the Motor Cycle racing world Dan likes nothing better than to get on two wheels of any kind and enjoy the thrill of the ride.
