Energy Ratings

Get a competitive advantage

Energy efficiency is invisible. If homeowners can't see the performance of your windows or doors, how will they prefer yours? When homeowners choose windows and doors for their home, they can see how they'll look but not how they'll perform. That’s why it's crucial to offer BFRC rated products and advise homeowners about energy efficiency. So that when your customers' homes are warm and cosy, they'll reward you with referrals.

Many installers still use discounting to win work. This is despite homeowners preferring installers who offer advice to those pushing price. Use BFRC rainbow ratings to show simply that an A-rating is better than a B-rating.

How BFRC rainbow ratings work

Advise customers to fit more energy efficient products

When trying to win new business, homeowners prefer being advised that to feel they're being sold to. Using BFRC ratings to give customers the evidence they need to make the right choice of windows and doors for their home's energy performance requirements, gives them confidence to appoint you as their installer.

Comply with Building Regulations

Building regulations stipulate that replacement windows must be rated B or above and doors B (or C if more than 60% glass)) or higher, except in historic properties and conservation areas. FENSA installers can have BFRC ratings free of charge when their frame supplier is BFRC registered and has the appropriate documentation. BFRC ratings do much more than comply with building regulations, they help your customers choose the right energy performance to make their home more comfortable to live in.

Proof of performance certificate

Provide homeowners with BFRC energy performance certificates that confirm the rating details of the window products installed. A certificate can be ordered when registered your installations with FENSA.

BFRC uses the UK’s most well-known, well understood and widely used A++ to E “rainbow” energy performance rating labels for windows and doors – similar to those on fridges and washing machines. BFRC rainbow ratings show the complete energy performance of the whole window or door including thermal transmittance, solar factor and effective air leakage.

Homeowners recognise our labels and understand what the ratings mean. To them, a BFRC energy rating represents proven energy performance and will help set your products apart from those recommended by your competitors.
U-value is a measure of heat transfer across a product. It is commonly cited when describing a window or door’s energy performance yet on its own is not enough to provide a comprehensive energy rating. That’s because there is no direct correlation between U-value and energy rating: it is possible to achieve an A rating with U-values ranging from 1.0 W/m2K to 1.7 W/m2K.

BFRC ratings go further by taking into account U-value as well as G-value (solar gain) and L-value (air leakage). Each of these values is calculated independently and in accordance with EN and ISO standards, leading to a more comprehensive rating of the product’s complete performance.
BFRC independently assesses and approves manufacturers of PVCu, timber, aluminium and steel frame windows, and manufacturers of external pedestrian and glazed (French, folding and sliding) doors. Each BFRC Approved Manufacturer is periodically inspected to ensure they are continuing to supply correctly rated products.

For the best results when installing energy efficient windows and energy efficient doors, always use BFRC rated products from BFRC Approved Manufacturers. This way, you can be sure that the products you recommend have been proven to perform as promised for heat loss, solar gain, and air leakage.
