Needed some work done that couldn't be completed until other work was done, and ERG hung with me while I was bounced around through that without a word of complaint, even though I know their scheduling got messed about as well. When they did show up, they immediately put on masks without a word of argument (more rare than should be the case, unfortunately) and did a superb job very efficiently. I did feel that each of their teams (sales, customer service and installers) were consistently courteous; I recommend ERG without hesitation.

Great company to deal with. Even when you know exactly what you want the surveyor will help with suggestions for improvements such as a wider door so our customers can fit through with their luggage etc. They finished the door off beautifully even adding a little extra trim on the inside that I requested to make the finish perfect. I would highly recommend this company and will definitely use again. The whole team are very helpful from salesmen, to fitters, surveyor and office staff...superb..thank you

We recently (April 2025) had a new front door and four windows installed in our house in Fortrose, Highland Region and are delighted with the high quality of the products and the skilled workmanship of the installers.
The composite door is of the high quality we were looking for since our house faces the sea (about 150 metres away) and the prevailing wind. Despite several days of severe gales and driving rain, it has already proved its worth - an enormous improvement on our previous door which although double glazed allowed the wind to penetrate round its edges.
The four PVC windows we had fitted on the north facing side of the house are also impressive. As well as having a high standard of insulation, they are also very attractive to look at, as has been commented on by several visitors.
The whole process from the first survey through to final installation was first class, especially the efficiency and friendliness of the staff from salesman, surveyor, receptionist and installers.
We should add, that we had a conservatory and garage conversion carried out by ERG Scotland about five years ago and were also very impressed by them.

The men from ERG windows Invergordon were very nice. They got on with the work and the job looks great ...I'm very pleased with the results 😊

Really human interaction with the firm. First the salesman was polite and considerate, second the office were really good to deal with and lastly the fitter worked hard, was professional and good humoured. The door is great and looks just how we wanted.

We engaged ERG to replace our old windows and install new patio sliding doors onto a new decking area. The ERG team were responsive to our requirements, completed the installation quickly and efficiently and left the site perfectly tidy. The work was completed in 2022, and I have delayed this review for 2.5 years in case there were any subsequent problems - there have not been, and we are delighted with the work. We have no hesitation in recommending ERG.

Ordered 2 composite doors front & back of home address. Impressed by ERG price and payment options initially so ordered products through them. Very professional fitting of doors and delighted with communication and after sales service. Excellent guarantee so peace of mind for the future. Would certainly recommend them for this type of work.

Kieran was brilliant, polite friendly and efficient, he did a great job we are very pleased with his work. Happily use ERG again and would recommend them. Thanks ian

We live on Skye and had our conservatory rebuilt by ERG Scotland last August (2024) as our old one was leaking and was too hot in summer and too cold in winter. ERG replaced all the windows and doors and put on a fantastic new "Ultraroof". I decided to delay writing a review until after it had endured its first Skye winter and everything the elements could throw at it over the recent months including some severe hurricane force storms. I am thrilled to say the new conservatory has passed its initial test with flying colours. We now have a wonderful room which we can get much more use from throughout the year. Add to that the friendliness and helpfulness of the team that installed it with minimum fuss and exactly when they said they would and I really can't praise and recommend ERG Scotland enough.

We heard great things about ERG, their service, quality and customer care - so having checked around with other companies ERG came out tops! We had a tremendous service from Colin in Sales, David the surveyor and finally the most important part the installation by James, who did an outstanding job in fitting our new windows - absolutely faultless! We highly recommend ERG for their quality and customer service which was outstanding and WOW a 20 year guarantee! Hunters, Wick

Thoroughly professional company providing a quality product at reasonable prices. A glazing company I can heartily recommend. I will use them again. From deciding on product to installation I can't fault any of the team. Every one who I had dealings with was polite and efficient

There are many glazing companies out there so it is often difficult to find one which actually lives up to its advertising blurb. ERG were recommended to us by friends and local tradesmen who had used them in the past. I have to say, we weren't disappointed. From start to finish the people we dealt with were thoroughly professional, courteous and efficient.

The products are of an excellent quality at competitive prices and were installed with care and respect for our property by a team of two who completed the work in a morning.

I wouldn't hesitate to recommend ERG to friends and neighbours and look forward to having further work done by them in the future.
