We did it! EWI Store has been shortlisted as a finalist in The Lloyds Bank British Business Excellence Awards in the category Small-To-Medium-Sized Business of the Year. This award celebrates resilience and innovation within some of the UK’s best businesses and we are so proud to have been shortlisted for this prestigious award!

What is The Lloyds Bank British Business Excellence Awards?

Attracting a variety of organisations, from small startups to large corporations, the Lloyds Bank British Business Excellence Awards is the largest and most comprehensive business awards programme in the UK. These awards acknowledge businesses that find new ways to support their communities and where employees thrive in times of hardship. This prestigious award is only awarded to businesses that are able to demonstrate clear processes aimed at supporting their local communities.

What Have We Achieved This Year?

Many have struggled over the past year and, to further support our community of homeowners, installers and architects, we have invested heavily in our training. This training is aimed at both new and experienced installers who are looking to either gain the necessary skills for the industry or to maintain their professional development and keep up to date with the latest processes and techniques. This year, we created an educational CPD (Continual Professional Development) programme aimed at architects which we have successfully had approved by the Royal Institute of British Architects (RIBA). This shows that our CPD course is of high quality and meets the very stringent criteria that are required to gain RIBA approval.

Here at EWI Store, we handpick only the highest quality products to sell in our stores. We stock the full range of products from EWI Pro who are well known for their supreme range of silicone renders. Their Premium Bio Silicone Render is an award-winning render, resistant to cracking, biological growth and discolouration and thereby providing a stand-out finish for years to come. By selecting only the best products, we ensure long-lasting and high-quality results for our community.

As usual, we would like to thank all our customers for their continued support. Make sure to keep your eyes peeled for future announcements!

Is External Wall Insulation Expensive?

Many of us here in the UK are interested in the idea of External Wall Insulation, with a vast range of benefits both environmental and financial it is easy to understand why. The biggest reservation many people have is regarding the upfront cost of the External Wall Insulation installation process. In today’s blog, I will explain the costs and hopefully put your financial worries to rest!


The process of External Wall Insulation has many components; the price accounts for the required insulation materials and labour costs. The cost of EWI materials will depend on the size of the project but also what EWI materials you choose. Not only do the prices of materials vary, but some materials require fixings and some require adhesive which will also need to be accounted for within the price. This means that the cost of your EWI system will depend entirely on the specific needs of your project.


Calculating the cost of the External Wall Insulation Materials

As explained above, there are a lot of components to consider when calculating the price. Luckily, we have a great solution for you; not only do we have a fantastic team on hand who can provide you with a quote, but we also have an easy-to-use EWI Materials Calculator tool that takes all of the faffs out of the calculation process. If you would rather have a helping hand and some guidance, just give us a call on 02033974067.


What is the EWI Materials Calculator?

The EWI Materials Calculator is an online tool that enables homeowners, installers and architects to quickly and accurately calculate the correct EWI materials needed to meet their requirements for their next project. The calculator will ask a series of questions to gather how much the system will cost depending on your needs.

Average External Wall Insulation costs:

EWI Typical Cost
Mid-terrace house £4,000 – £6,000
Semi-detached house £8,000 – £10,000
Detached house £12,000 – £14,000 +


This may seem like a scary amount for some but if your property has solid walls, you could save between £115 and £360 a year by installing External Wall Insulation. This means, over time, the External Wall Insulation will start to pay for itself. You have to remember that not only will you save on your heating costs, but you will also reduce the amount of CO2 emissions your property emits into the atmosphere which will help the environment. Your External Wall Insulation job will also be finished with your choice of render and colour, providing additional value if your brickwork is damaged, worn down and in need of a makeover.

If this still sounds like too much for you, there is government-backed support that you could be eligible for. Currently, there is a subsidy called the Energy Company Obligation (ECO) which was launched in December of 2018. The scheme runs until the 31st March 2022 and focuses on customers with low incomes and considered to be in vulnerable situations e.g. living in fuel poverty. Under ECO, grants are available to cover all or part of the cost of energy efficiency measures. Ask your energy provider for more information on this scheme.

Trade Installers get fantastic prices and warranties on the system

As an installer, you may well be eligible for our trade discount prices too; so, not only will you get a BBA-approved external wall insulation system delivered directly to the site, but also the materials you need at a great price. As a trade partner, we are also able to offer system warranties provided the installers have been on our free training course.
