Charities we've supported

At Acorn Windows we firmly believe in giving back something to the local community, without whom we would not have succeeded since we started way back in 1989.This may involve installing windows at no charge or helping out with a charity or community project.

The Benefits

Weather Protection

We use a neoprene gasket on both sides of the opening vents to eliminate draughts and rain. The noise reduction from this system is amazing.

Controlled Ventilation

All of our windows have a “night vent” facility which enables you to leave the window partially open whilst still secure.

No More Painting

Our PVCu frames are guaranteed to retain their colour, requiring only the occasional wipe over with a soaped cloth, to maintain their pristine condition.

No Unsightly Holes

Our PVCu system has concealed drainage so you do not have the unsightly drainage caps so often seen.

Fire Escape Hinges

We install fire escape hinges where current Building Regulation Requirements state they are needed.

Secured by Design Police Approval

All our products are fully reinforced which has enabled us to be approved and acredited with the scheme operated by the police.

External Sill Range

There is a selection of sills available to complement any home.

Window Cleaning Made Easy

The windows open to 90º allowing the outside of the window to be cleaned from the inside.

Peace of Mind

We are continuously upgrading our locking systems to deter even the most determined of intruders. We use the latest Saracen shootbolt locking with anti jemmy hinges.

Range of Handles

We use “push to open” handles which are both easy to use and highly secure. Available in white, brass, black or chrome.

Noise & Thermal Insulation

28mm Double glazed sealed units with an optimum air gap, provide superb insulation.

Quality Marks

At Acorn Windows we firmly believe in giving back something to the local community, without whom we would not have succeeded since we started way back in 1989.This may involve installing windows at no charge or helping out with a charity or community project.


Acorn Windows have been awarded a Secured by Design Licence.

Secured by Design is the UK Police flagship initiative supporting the principles of “designing out crime” by use of effective crime prevention and security standards for a range of applications.

Currently Acorn Windows are the only retail installer of PVCu windows and doors in Nottingham to be endorsed by the Police. We are very proud that our windows and doors meet the specifications required by the Police and offer the highest possible security innovations.


Building Regulations for Your Windows – FENSA (registration number 16983)

On the 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.

You can meet your commitments under the Building Regulations by using Acorn Windows, who 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 Acorn Windows to certify through FENSA that the installation meets current Building Regulations. FENSA will register your installation electronically with your Local Authority and send you a certificate which records we have certified that the installation meets the appropriate Building Regulations.

A FENSA Registered Business, like Acorn Windows, is required to understand the Regulations and be capable of installing a product in your home which meets requirements. We will therefore advise you on the design of windows and doors and see that the installed windows have the correct thermal performance. Acorn Windows is not permitted to fit non-compliant products that would put you or your installation at risk. By registering your windows you will avoid any problems when you come to sell your home.

FENSA also organise, on a random basis, the inspection of a number of our installations to ensure that Building Regulations are being met.

Since we joined FENSA in 2002 not one of our installations has failed a FENSA inspection.
