Why is it Important to Choose a Verified Installer?

Selecting a trustworthy installer is vital when undertaking work to your home. You can gain confidence in your choice by ensuring the installer is Checkatrade and FENSA approved, and a member of the Plastic Windows Federation. None of these approvals are required by law, so an approved company indicates and willingness to provide the very best for their clients.

What is Checkatrade and Why is it Important?


Checkatrade is a trusted online platform, designed to help homeowners in the UK find trustworthy and reliable installers.


Checkatrade verifies installers by using 12 key checks, these including;

Identification, proof of address, qualifications, open-source check, court judgements for both personal and business, company history - requiring proof of good trading, financial history, duplicates, director history and company reviews.


Becoming a member of Checkatrade involves committing to delivering a high quality of workmanship, maintaining high standards of personal conduct, working safely and ethically, communicating clearly and honestly and agreeing costs and contract terms upfront.


At Insulation Services we strive to achieve all of the above to the best standards, our 644 customer reviews have given us an overall score of 9.88 out of 10!



What is FENSA?


FENSA is a government-authorised scheme that monitors installer's compliance with building regulations for replacement windows and doors. All FENSA approved installers are regularly assessed to ensure the standards are continually maintained.


A FENSA certificate indicates that an installer is compliant with the current building regulations and it can also be useful when it comes to selling your house. A FENSA registered company will certify all installations and you as the homeowner will receive a certificate to show that your windows and doors have been installed compliantly. This helps to install trust in the new owners when looking to sell your home. 



What is Plastic Windows Federation?


Plastic Windows Federation provides insurance backed guarantees for members who install windows, doors, conservatories, roofline products and solar panels. This is only available to approved installers who must pass a strict quality approval process, ensuring you're in trustworthy, capable hands. PWF helps you to have peace of mind when trusting in an installer, as you can be sure your products are covered under guarantee, even if a business ceases to trade for any reason.


Plastic Window Federation policies protect the installation of PVC-u, aluminium, hardwood, softwood and composite windows, doors, conservatories, replacement roofs and roofline products for a 10 year guarantee period.

"We have used Insulation Services previously and have always been very satisfied with the service provided. Office staff very friendly, helpful and quick to respond. Fitters extremely good with minimal disruption and arranged for some (manufacturer) damage (which we could not see) to be replaced. Have used other similar firms in the past but Insulation Services is by far the best of them all."
