Who We Are
The combined service of the National Replacement Window Advisory Service (NRWAS) and the National Conservatory Advisory Service (NCAS) is a unique and proven alternative way of finding the right people to improve your home.
- A Consumer Organisation
We are not a trade association and do not accept membership fees. We are totally independent from the companies we may recommend, as well as from other installation companies and industry groups.
Our commitment, through our philosophy and service procedures is to you, the consumer.
Whilst we work very closely with registered installers, manufacturers and trade specialists throughout the UK, we serve your interests first and foremost and our objective is to give you qualified, independent advice. We offer you realistic and practical information for your project and help you find the most cost effective way of completing your home improvement, on-time and within budget.
- A tried and tested service
The service was conceived in 1992 as a regional service, and has grown over the subsequent years, into a multi-faceted, National home improvement organisation, having helped tens of thousands of home owners throughout the UK to find the right products, prices and installers for their project, without the need to go through a multitude of sales people & companies and the "hard-sell" and confusion, which often accompanies the quest for the right result.
- Our policy is simple
We seek the same requirements as you - value for money, and a good standard of both installation and materials from reliable, well-run companies which will not let you down.
