We use all of experience and knowledge to advise you and help you to select the right solution for your own project and your own unique requirements. We advise you on the technologies available, selection of the right products and manufacturers for the job, the best system options and components available, the best control options and products available and advise on available grant funding and how to access it!

This allows us to compile an initial outline for your consideration and then a detailed specification for your approval for your project. From this we can give you a fixed quotation for the works and you are free to get other quotes based upon this detailed specification. For your peace of mind we will even refund our consultancy fee to you (terms apply) when you proceed with us for the installation.

If you proceed with another installer, then you know that you have got exactly what you wanted, hassle free, with no pressure, no dodgy sales or special “today only deals” or “one off” discounts - at the most competitive, fairest and realistic price. We don't think you can get a better or fairer than that!

So why consult?

When companies are competing for business, they have to be just that - competitive. But what does a price tell you? If you get 10 estimates, you get 10 prices. Why is there such a variation in the range of the prices? What are the reasons for the price variations and what does it mean?

Unless all the companies are pricing to the exact same detailed specification and parameters - they mean absolutely nothing! There is no other comparison other than the price! Its just a lucky dip - Good luck!

So why are they all charging different hourly rates?

A good professional company knows its worth and charges accordingly for professional quality installation that is fully compliant with all rules and regulations in force and gives good customer service. If you pay peanuts - you get monkeys! Beware of cheap installations.

Why are they all differing in time to complete the works?

This will vary depending on quality of workmanship and quality and specification of installation. Speed isn’t everything! Why cut corners just to save time?
