Our Values

Nothing is more important to us than building and maintaining strong relationships with our clients. To do this, we rely on three vital elements:

  1. Staff
  2. Support
  3. Professional standards

Our own fully trained staff

Delta Security relies only on fully trained in-house staff. By avoiding sub-contractors, we keep total control over the quality of our work. This means a first class job for you, completed on time and without fuss.

Ongoing security support

We can support almost every security job with our optional gold star maintenance package. This takes care of all costs related to future servicing, call-outs and repairs* and gives you total peace of mind.


Professionally approved work

Delta Security is approved to European Standard ISO 9001.

The security industry's leading governing bodies approve our work and company. This keeps us up-to-date with the latest technology, rules and regulations and ensures we maintain our professional standards. The organisations that approve our work demand the highest standards, and have exacting rules. Some carry out regular inspections, while others seek frequent references.

Be confident you can trust our work from memberships, certifications and approvals that include:

Ask for yourself

If you would like direct, personal reassurance about the quality and efficiency of our staff and services, we can connect you with independent contract managers, surveyors and consultants who will be happy to discuss our work with you.
