Emerald's 10 Year Guarantee

We offer a 10-year insurance backed guarantee on all work we carry out. We also guarantee all deposits that are paid to us. This means that even from the point that you pay any deposit to us, you are guaranteed that all money you pay to us is backed by insurance that you can trust. We issue you with a certificate covered by the Plastics Window Federation (PWF).

The PWF is the market leader in providing quality insurance protection to customers of its network of member companies. Emerald is a proud member of the PWF. This means that we have been selected from a number of companies large and small that provide replacement windows, doors and conservatory installations of consistently superior quality. The aim of the Federation is really to protect the general public when purchasing uPVC products from its members. What this means is that as well as the continuous monitoring that the PWF does, it also offers an insurance backed guarantee to the customer in case the member company ever ceases trading.

This is why you are given an insurance backed guarantee when choosing Emerald. With Emerald you are protected. Emerald offer a full 10 year guarantee on all of our products, covering ever aspect of both materials manufacture and installation.

However, a guarantee is only as good as the company that backs it, and the Emerald guarantee is underwritten by a FENSA approved independent insurance company.

In the unlikely event that Emerald goes into liquidation then your Emerald products will be covered for the remainder of the guarantee period through the insurance company.


On 1st April 2002 the replacement of windows and doors came within the scope of the Building Regulations for England and Wales. Therefore replacement of windows and doors in your home are subject to the requirements of these regulations. This was one of a number of changes designed to improve the thermal efficiency of our homes and to assist the government in meeting its commitments to reduce CO2 emissions under the Kyoto Agreement. It will also mean that our homes are warmer and use less energy. You can meet your commitments under the Building Regulations by using Emerald, as we are fully approved by FENSA.

The FENSA scheme was set up by the Glass and Glazing Federation with the cooperation of the Office of the Deputy Prime Minister, the government department responsible for Building Regulations, as a Competent Persons Scheme. This scheme enables Emerald to certify through FENSA that all installations meet current Building Regulations. FENSA will register your installation electronically with your local authority and send you a certificate which records that we have certified that the installation meets the appropriate Building Regulations.

A FENSA registered business such as Emerald is required to understand the regulations and be capable of installing products in your home which meet all requirements. We will therefore advise you on the design of windows and doors, and see that the windows have the correct thermal performance. Emerald is not permitted to fit non-compliant products that would put you or your home at risk. By registering your windows with FENSA you will also avoid any problems should you decide to sell your home at any time in the future.

According to Trading Standards, it is estimated that more than 106,000 complaints about rogue traders are logged every year. Disreputable companies carrying out substandard work wastes £1.5billion each year, consumers have to fund the repairs to the damage they cause. Rogue tradesmen are more commonly known as cowboys. They are people that carry out home improvement work without the necessary qualifications and experience. Cowboys take advantage of their customers, often over charging for services and causing damage to homes. Using a window installer registered with FENSA will help you to avoid falling victim to cowboy tradesmen.
