Choosing a supplier for your home improvements can be a sticking point for many people. If you’re in the market for external insulation, solar panels or any other form of home improvement you want to be sure that you are dealing with a reputable firm.


How can you be sure that the quality of the work is up to scratch, and that they are a company you can trust? There’s a lot of help available to help you in your choice, so that you work with a reliable, trustworthy contractor. Here is our advice on how to pick the best supplier for you.

Experienced installers

We recommend meeting your installer or contractor face to face to allow you to ask questions and get a feel for their experience and how they work.

An experienced installer will talk you through the choices available to you, and will objectively advise you of the best options, even if that means a lower cost to you.

They should willingly tell you about other similar projects they have worked on in the past, sharing pictures so that you can see the quality of their work. You want to be sure that they are experts in the type of work you are asking them for – as you want an expert rather than a jack of all trades.

Quality of workmanship

Does the firm have the required qualifications and snipaccreditations? You wouldn’t think to use an unqualified doctor, so the same case applies for energy efficiency installers.

“NICEIC approved contractor” is also known as “PAS2030:2017 certified”, and it's the industry standard for contractors working in the building sector. It provides assessments and certifications to ensure that the work being done is safe and of the highest standard. You can check the details of any firm on their website.

For any structural changes to your building you will want to be reassured about the firm’s understanding of Health & Safety regulations. Not only should the site itself be safe, but the transport of materials, the working conditions of their team and company processes should all comply with Health & Safety legislation.

CHAS accreditation and Safe Contractor are both recognised accreditation schemes that demonstrate to you that your contractor is up to date with their Health & Safety obligations.

Customer recommendation

How satisfied are past customers of the firm? Word of mouth recommendations are the strongest endorsement a firm can receive. It is also worth searching online for reviews from past customers to find out what they think of the quality of work delivered.

Some firms also operate their own customer survey, in which case do they publish the results? Find out what other people have said about the firm to get a general impression of how well regarded they are by others.

Their customer service post-installation is also important. Good firms want to ensure that their customers are satisfied and will want to hear from you if you have any questions post-installation. Check that their contact details are easy to find in case you have any questions after the work is complete.

Best value installers

Each contractor may have quoted based on different grade materials or components, a different finish or quality render. A good contractor will have a direct relationship with the manufacturers of the materials they plan to use, and will be therefore able to secure you a good deal on high quality products.

Their knowledge of the products on offer will ensure that they are up to date with the latest innovations and will be able to advise you on the options available to you ranging in quality and price.

As with everything, you get what you pay for. If you’re looking for a high-quality finish to your project, whether it is external wall insulation, rendering or other energy efficiency measures then the cheapest quote may be a false economy.
