what we do

Myriad specialise in the service and maintenance of commercial and industrial biomass heating plant, allowing you to keep your building or site running smoothly and profitably.

If you’re a commercial or industrial Gilles biomass boiler owner, you can maximise your income from RHI, increase the lifetime of your biomass heat and power systems and minimise breakdown incidents.

How is this achieved? By giving you access to a suite of biomass services, unrivalled support and a proactive approach from our fast-growing central UK service desk team.

And with nationwide coverage, you’ll be supported wherever you are.

Service Contracts

If you would like ongoing support or preventative maintenance and servicing, you could benefit from one of our biomass service packages, detailed in the table below.

For many of our clients, this is their preferred arrangement as it provides excellent balance of cost between Service and Maintenance (call outs/repairs). Managed Servicing will reduce the number of breakdowns and part failures.
