UPVC stands for Unplasticised Poly Vinyl Chloride. Also sometimes known as vinyl, it is a material that is rigid, long lasting, durable and low maintenance. UPVC double glazed and triple glazed windows offer high energy efficiency and are designed to be strong, robust and secure. We can supply and install a range of upvc window styles to compliment all properties from Woodgrain to White, Anthracite Grey to Irish Oak.

UPVC has become accepted as the most practical, affordable and stylish material for replacement windows and doors in the UK. Over the last 40 years, UK manufacturers have made considerable investment into their machinery and processes to produce the high quality products that we can now supply.

Maintenance Free

UPVC windows will never rust, rot, peel, are fully recyclable and lead free. Our windows are supplied with easy clean hinges that only need an occasional wipe down with warm soapy water.

Quiet and Warm

Our windows are all made to measure and A+ rated as standard. The window frame and sash are multi chambered to reflect heat back into the property, whilst also preventing it from escaping. The gap between the window panes is filled with Argon gas to keep the cold out, and the separating spacers are coated with a low conduction material to hold more heat. In addition, the high-quality seals are double weather resistant to prevent rain or draughts incurring into your home. All of these features deliver excellent thermal efficiency, keeping your home warmer, quieter and helping to reduce your energy bills.

Safe and Secure

All of our windows meet the British Standard for security, ensuring that your home has the highest level of protection. We use an internal glazing bead to prevent the glass being removed from the outside. In addition, our windows are all fitted Shockbolt Locking Secured by design locking system and Fire Escape as standard.

Assured Certified

We are an Assured Certified installer. Assure is an official, UKAS-accredited Competent Persons Scheme authorised by the Ministry of Housing, Communities and Local Government (MHCLG) for the replacement of windows, roof windows, roof lights and doors in England and Wales.

Every project is automatically registered and backed by a 10-year warranty, providing further peace of mind and guaranteed satisfaction for our clients.

We can provide a range of UPVC window styles, including:

UPVC Casement Windows

A casement is a window that is attached to its frame by one or more hinges at the side. They are used singly or in pairs within a common frame, in which case they are hinged on the outside. Casement windows are often held open using a casement stay.

Astragal Bar Windows

Astragal bar windows are where the bars are planted on to the glass. They separate panes of glass, giving the effect of traditional period features.

Georgian Bar Windows

Georgian bar windows are where the bars are sandwiched between the pains of glass, creating the Georgian window style but remaining easy to clear and maintain.

Residence 9 (R9) Windows

Residence-9 Window – R9 is manufactured from a modern composite material to give a virtually maintenance free finish. It is a new window system designed to replicate the 19th Century Flush Timber Windows.

Vertical Slider Windows

Our vertical slider windows maintain the period features of Georgian sliding windows without the associated draughts, rattling or poor security. Our leading-edge design sliding upper and lower window panes combine a smooth glide operation, with high quality hardware and brush seals for exceptional draught proofing and thermal efficiency.

Tilt & Turn Windows

Tilt and turn windows are some of the most versatile UPVC windows available. The windows open inwards to allow you to clean the glass without leaning outside, whilst the tilt option provides ventilation without compromising security.


How much maintenance will my windows require?

Hardly any! We would recommend using a good quality glass cleaner to regularly clean your windows and soapy water only to clean window frames.

Are they expensive?

Compared to other window materials, such as timber and aluminium, UPVC is more affordable. If you would like a free, no obligation quote please get in touch with us.

Should I change all of my windows at the same time?

There’s no need to change all your windows at once. If it is more convenient for you and your budget, we can install one or two windows at a time.

What styles are available?

We have a wide range of window styles and colours available to suit all types of property. Gone are the days of simple white UPVC window frames, now you can choose from wood grain, grey and oak amongst others.

Can shutters be fitted to UPVC windows?

Yes. The process of fitting shutters to UPVC window frames is the same as timber frames because they are usually fitted to the building rather than the frame itself. We would recommend using a specialist company to ensure clearance from handles and hinges, and easy opening of the windows.

How long do UPVC windows last?

The life expectancy of UPVC doors and windows is around 30 years.

Are UPVC windows energy efficient?

If fitted correctly, UPVC windows can achieve energy ratings as high as ‘A’. This is best possible energy efficiency within homes and exceeds the industry requirement.

Will I need planning permission for new windows?

Planning permission is not normally needed for repairing, fitting or replacing doors and windows, unless your building is listed, or you live in a conservation area. If this is the case, we recommend you check with your local planning authority before going ahead.

How long will installation take?

Installation time depends on the number of windows and style, but generally a whole house (8-10 windows) will take 1-2 days to complete. When we visit your property to carry out a survey, we will understand the scope of work required and be able to give you a more accurate time estimate.

What happens to my old windows?

If your old windows are UPVC, we will send them to a recycling facility where they will be used to make new energy efficient products.

Will I need to redecorate or replaster after installation?

It is possible that some plaster work will be required around the window reveals, but our installer will carry this out for you.

Will I need to remove my curtains or other window dressings?

Yes, we will need full access to the windows to carry out the installation.

Will the installer need access to my home?

Yes, we need access to both the outside and inside of the property in order to replace the windows. Our installers are all fully trained and will make necessary arrangements with you to access your home. We respect any health concerns, for example COVID, and will clear away all mess at the end of the job.

We welcome you to contact us for a no obligation appointment, where we can show you samples of our windows and talk you through the many product choices that we offer. Once we have agreed a design and specification of product with you, we will provide you with a free written quotation and timescale for installation.
