Stages to saving energy

Arrange for us to survey your part of your site

We will provide proposals with costs and paybacks

You could order a pilot to prove financial savings

We design energy-efficient solutions to common lighting problems:

Old-style sleepy 'cave-effect' lighting converted in minutes to 'wide-awake' direct-indirect lighting... also saving up to 65% of energy!

Contact us on 0845 224 2254 to arrange a discussion about your site, your goals and your energy-uses.


You can achieve the maximum savings with the minimum capital-expenditure.

The results are lower energy costs, and often better appearance or improved lighting for staff, students or visitors.  Areas in North London, Hertfordshire Essex Cambridgeshire and Bedfordshire we can visit easily to survey

We work with many publicly-funded sites, and private organisations from offices, to hotels to factories and warehouses, where payback can be as fast as 12 months.
We can discuss funding arrangements and pilots to help ease your way.
