About Us

Company Background

Here at Winstanley Windows, Robert has been in the Glass & Glazing industry since 1977. Starting as a trainee at a well known Folkestone glass company, after leaving school, he was taught all aspects of the industry from glass cutting to fitting shop fronts. From here he moved to another well known, at the time, uPVC window manufacturing company where he fitted windows, doors and conservatories for over 10 years; during which time he also obtained a City & Guilds in Carpentry.

In 1993 Robert set out on his own, initially working for himself, Robert covered the selling, surveying and installation process of the business. “Recommended by Reputation” soon meant that the company saw rapid growth. The workforce grew swiftly and now boasts teams of employed fitters, a separate glazing division and full time service department. Many of the staff have been at Winstanley Windows since just after the outset; with some starting as young lads who are now out and about as team leaders.

Covering most areas of Kent, East Sussex and certain areas of Outer London our fully trained and highly expert team of fitters offer both peace of mind and professional customer service when installing and completing your home improvement project.

Winstanley Windows prides itself on the reputation of Robert and his staff coupled with the standard of work and client service levels offered by the company. These are values that we continue to work by and are pleased to be “Recommended by Reputation”.

Staff Training

Our continuous staff training programme has provided our employed staff with the key skills and knowledge required to safely and competently carry out their work. All employees are qualified to a  minimum NVQ Level 3 with plans currently in place to upgrade to NVQ Level 4. With various Health & Safety training days scheduled throughout the year, to ensure current legislation and standards are  adhered to, our fitters also train in Job Risk Assessment and First Aid.

With our entire on site workforce holding current CSCS cards (Construction Skills Certification Scheme) they have had to demonstrate their occupational competence and have passed the Construction Skills Health and Safety Environment Test. This ensures our qualified team of fitters are proficient to work on building sites for commercial developments and refurbishments.

Benefits of using a FENSA registered company

FENSA is the industry standard for replacement window and door installers self-certifying compliance with the building regulations.

Here is why you should look for the FENSA logo when having replacement windows and doors fitted in your property:

Save time and costs:

  • You do not have to register your window or door installation with the local authority yourself. Not only is the FENSA approach much faster and easier – it will also save you up to £250!
  • Compliance with the Building Regulations without the added cost and time of arranging assessment by Building Control
  • If you own properties across different local authorities – for consistency of quality and price, you are able to use the same FENSA installer for all installations, as they can work in all Local Authority jurisdictions

Confidence in FENSA installers:

  • FENSA is the brand trusted by all local authorities, industry and government.
  • An independent report commissioned by the Government found FENSA to be the most successful of all competent person schemes to date in the UK, across all industries.
  • Vetting: All FENSA registered companies are continually re-assessed by an independent inspection body to ensure consistency of Building Regulations adherence and service.
  • Nearly 9,000 companies nationwide have joined FENSA which include glazing companies, builders, national and smaller home improvement companies, local authorities, housing associations and property developers. If all these companies trust and use FENSA, consumers & homeowners can too.
  • FENSA does not demand any specific brand of insurance from its installers – homeowners and installers have freedom of choice over insurance providers whose policies are underwritten by ‘different’ insurance companies (FENSA is not insurance-led)
  • FENSA proactively protects consumers from the cowboys – not only by withholding the scheme from those unable to pass FENSA’s independent assessments; but also by reporting to Local Authorities and Trading Standards companies who erroneously claim FENSA registration, to enable prosecution.
  • Customers are able to provide a rating score for installers on the feedback form which can be found on their website www.fensa.co.uk/feedback.aspx
