FAQ's Replacement Swish windows, doors and conservatories

Before you email us with a query please take the time to read though our frequently asked questions

What is the Window Energy Rating System and
how does it affect me?

Much like white goods windows are also rated for energy efficiency. Ratings of A, the highest, through to G, the lowest, are available.

First introduced in the Spring 2006 the system is designed to give a clear indication to consumers as to the energy performance they can expect from their windows. It measures the whole window including the frame and the glass and takes into account 3 factors which influence the energy performance – heat loss, solar gain and energy lost through air filtration.

The minimum level of window that can be fitted now is an E, the minimum recommended by the Energy Saving Trust is a C. The Twentyfour-Seven system from Swish is designed to achieve up to an A rating, visit our Green PVC-U page to find out how much you could save by fitting Energy Rated Windows or talk to your Authorised Installer about the most suitable rating for your home.

What guarantees are available?

Your guarantee will be direct with your Swish Authorised Installer, make sure you discuss a 10 year insurance backed guarantee with your installer.

I have condensation on the inside of my windows –
are they faulty?

Condensation is a naturally occurring and not indicative of a fault with your windows. As our houses have become warmer the problem has become more apparent. We now have sophisticated heating systems and have eliminated draughts from doors and windows as well as insulating our lofts. All these elements combined mean we have reduced the level of ventilation into our homes.

To reduce the amounts of condensation consider the following options:

Open a section of window to provide natural ventilation.
Draught proof your internal doors and keep doors shut to prevent water vapor transferring from your kitchen and bathrooms to the rest of your home.
Where possible locate your radiators under the window will help keep the temperature on the inside of your glass at a reasonable level.
Fit a ventilator/ extraction unit in the kitchen and bathroom.
Fit night ventilation facilities in your bedroom windows such as a ventilation grill in or above the door.

I have condensation between the two panes of glass of my double-glazing – what can I do?

Unfortunately this is an indication that the sealed unit has failed. Contact you installer who will be able to fit a replacement sealed unit, check with them whether the sealed unit was covered by a warranty when installed, many are for up to 15 years.

Will I need planning permission for my conservatory?

This depends on the size of your planned conservatory and whether you have extended your home previously. For detached and semi-detached homes you can add up to 15% onto the original floor plan of your home, or 70 cubic metres whichever is larger, without requiring planning permission. For a terraced house the size in reduced to 10% or 50 cubic metres.

Your Swish Authorised Installer will be happy to advice and if required assist you in applying for any planning permission required.

How much will my conservatory cost?

Such a high number of variables in conservatory design, size and materials make it very difficult to give an exact price. Your Swish Authorised Installer will be able to talk you through all of the options available and their cost implications. It is worth noting that investing in such options as roof vents, specialised heat reflecting glass and blinds can greatly increase your enjoyment of your conservatory and make it suitable for use year round.

How should I clean my windows and conservatory?

Always avoid solvent based or abrasive cleaners. Wash frames with soap and water every four months to remove grime and atmospheric deposits.

If required use a soft cloth to apply a non-abrasive cleaner suitable for plastics.
Take care not to disturb any sealant.
Clean the gutters around your conservatory as required removing leaves and debris.

How much will my windows cost?

All replacement windows and doors are made to measure for your home, there’s no such thing as a standard window size, design or colour. A Swish Authorised Installer will need to visit your home to carry out a detailed survey and talk to you about the wide variety of options available before being able to supply a quote to you.

How long will it take between placing my order and
installation starting?

This depends on the choice of window options you select. Foiled colours in particular will take longer but you should expect to wait on average between 3 to 6 weeks.
