Established over 40 years

Jargon free, transparent maintenance

At Triangle we have a maintenance solution to fit your demands. Whether its a 1-5 year service contract, an annual PPM strategy or ad-hoc callouts, our standard rates make budgeting easy and ambiguity free.


Estates, Property portfolios and office buildings are regularly being handed over to Triangle for compliance improvement following previous management and contractors neglecting their responsibility to maintain safety systems.  Triangle are a valuable asset to our clients and we relish a challenge.


Our 1-5 year service contracts include all M&E annual service items, providing our clients with a single point of contact for all your compliance demands. 

To improve site continuity Triangle have partnered with a specialist company for all disciplines outside of our remit allowing us to offer a turnkey solution for everything maintenance and compliance related.  This allows Building Managers to focus on their day to day operations.

As a UKAS BSI ISO 9001: 2015 approved company, our supply chain includes some of London's best specialists and they have all proven to be an asset to Triangle and our clients. 

Our clients are ambassadors of true quality.
