I have used ERG twice recently for my properties and on both occasions the service they have given me has been first class. Their quotations have been very competitive, communications have been swift and efficient. And the work was completed on time with no fuss. The staff are very friendly and very knowledgeable and I won't hesitate to use them again.

From initial enquiry, right up to completion, we found the service first class. All employees were polite, helpful and totally professional. There was straight forward pricing with no pressure. The fitter arrived promptly and worked non stop throughout the 2 days it took to complete the work. Our property was left immaculately tidy both inside and out. Would highly recommend.

Everyone was so helpful and the process, from getting a quote to installation, was quick and simple. Good quality windows and doors and installation team were very respectful of our property. Highly recommend ERG.

Brilliant service from ERG Windows. My new patio doors look fantastic and the quality is excellent. Kieran, who did the installation, was professional, friendly, and left everything spotless. Highly recommend!

From start to finish the whole experience was easy to follow from the initial meeting with the salesman who didn't pressure sell,the very efficient survey and probably the best and hardest working window fitter I have seen(Neil).Even the billing was exact and very well explained.

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.
