Established in 1998 by owner and managing director Simon Walker, award-winning SPS Timber Windows is a reputable specialist in the design, manufacture, installation and finishing of premium quality, energy-efficient, bespoke timber windows and doors, notably BFRC A-rated Accoya wood box sash windows and casement windows, French doors, single exterior doors and folding sliding doors.
SPS Timber Windows is endorsed by Which?, is FENSA certified, BFRC authorised, with our windows having been awarded an A-rating for its thermal energy performance and is BWF-approved and Trustmark accredited.
The company’s dedicated team of 27 includes very experienced, highly multi-skilled designers, joiners, carpenters, installers, decorators and administrative personnel whose common goal is to deliver excellence.
“Our customers, primarily in London and Surrey, are very discerning,” explains Simon. “Quality, longevity and authenticity are of paramount importance; they are keen to maintain or restore the original characteristics of their period properties and the vast majority of our customers, whether owners of new or period properties, also have a strong environmental awareness.
“Timber is the preferred choice for their windows and doors and our bespoke service, our ability to make to individual requirements, to replicate the designs and features of original installations with all the benefits of modern specifications, offers the ultimate appeal.
Improved energy efficiency, noise reduction, security and safety
“Our windows and doors not only serve to aesthetically enhance and add value to our customers’ properties and to prolong their original characteristics, but they also significantly improve them for modern living, with greatly improved energy efficiency, noise reduction, security and safety.
Examples of our completed installations
High quality, traditionally crafted windows and doors
“Our windows and doors are individually made, to exacting standards, in our London workshops and are installed and fully finished by our highly skilled craftsmen, installers and decorators.
“High performance double-glazing, high security locking systems, draught sealing, our advanced, low maintenance microporous paint system and the best timber available add optimum performance and durability to authentically reproduced designs.
“We are a very well-established, experienced, trusted business, offering a bespoke service. Our customers also appreciate the fact that we offer a comprehensive service, from initial consultation to fully completed installation, and that we manufacture locally. We have a Wimbledon-based showroom, where customers are very welcome to discuss their requirements and view sample windows, doors, glass, fittings.
“We continue to experience a complete volte-face in property owners’ perceptions of timber windows and doors. Certainly for SPS and our customers, long gone are the days of rotting, high maintenance wooden structures and a preference for plastic reproductions,” says Simon.
“Accoya wood has raised the standards of reliability and performance for timber windows and doors. This premium timber, with Class 1 durability, is guaranteed against rot for 50 years. Combined with our advanced, low maintenance microporous paint system, our Accoya wood windows and doors will last for many, many years. SPS Timber Windows was one of the first UK manufacturers to use Accoya wood and continue to use it as the best timber available.
Great products in high demand
“Demand for our bespoke Accoya wood windows and doors continues to be very high, such demand is greatly valued and, as part of our policy of continuous improvement, it is vital that improvements continue to be made to enable us to keep up with the demand,” explains Simon.

Having already outgrown two premises, SPS was becoming a victim of its own success and needed to find efficiency in the production process as its set-up of using spindle moulders, tenoners and all the traditional joinery techniques and processes had become a concern.
“Whilst the manual input of our highly skilled staff continues to be so very important for the production of our traditionally-made windows and doors, the need to meet the increasing demand for our windows and doors and to speed up production has necessitated the acquisition of additional state-of-the-art machinery.
Efficiency needed to be improved
“We carried out a lot of research as to which machine would be best for our purposes,” Simon explains, “we decided on the Crafter as this machine offered everything we needed. We made the right choice! Jaroslav Soukup’s extensive experience, advice and assistance were invaluable.
“The Crafter has enabled us to further improve the performance of our latest design of traditional box sash windows which have been awarded an A-rating by the BFRC (British Fenestration Rating Council).
“The whole process, from our initial enquiry with Ian Brown through to delivery, commissioning and training, has been excellent.
“Soukup arranged a demonstration and training in their modern facility in Prague for our workshop and installations managers, Eric Frimpong and Richard Fitch.
“The whole team at Soukup has been extremely helpful and has quickly assisted with any questions.The Crafter machine enables us to produce windows and doors to an excellent quality with greatly improved efficiency.
Increasing production capacity
“Producing each window takes less than half the time it took previously. Eric Frimpong, our workshop manager, is very impressed with the machine and with how much it has helped to increase our production capacity. We no longer require the older spindle moulders and tenoners and selling these has enabled us to free up some much-needed space.
“I, Simon Walker, am full of praise for the Soukup Crafter. We are very pleased with the investment we made in the Crafter and tooling and would highly recommend IWM and the Crafter machine. It is doing everything we had hoped it would do and more. Our expectations have been exceeded.
“Ian Brown will be our first port of call for any new machines we’ll be investing in to further improve our efficiency and productivity.”
