From start to finish the service has been amazing. We used the website to organise a meeting for a quote. Luke came out to us he was very knowledgeable and helpful! The installation team were great too, very professional and quick. Would definitely use 5 star again and recommend to anyone interested. 

First had a new sliding door fitted, which in total took almost five months. Measured incorrectly initially, and had to wait ages for the replacement. Doors satisfactory, and a discount was given for the problems encountered.
Second, had already ordered a new conservatory, to slightly enlarge old one, and again, measured incorrectly. Frequent calls, emails etc with quibbles about almost everything. 5* finally finished the project eleven months after beginning removal of the old conservatory, which was four months after initiating the project. Poor communication between all aspects of design, work, finishing. Final product is almost what I originally asked for. Not impressed, and very little was offered by way of compensation - had to fight tooth and nail for anything.

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.

This is the second time we have used 5 star windows. First time we had all our windows changed which have exceeded expectations and they look fantastic.
Most recently we have had a set of bi-folds doors to replace a window. I am absolutely over the moon with them, they look amazing, the quality is second to none and the service has been outstanding. They have given our living room a new modern looking twist whilst creating a great connection with the outside. I would highly recommend this company. I cannot thank them enough!

As above. Stronly recommend.

Installation crew (3 guys) were punctual, polite, very hard working, very helpful & nothing was too much trouble. Each evening they left our house very clean & tidy.
We are very impressed with the products, which replaced 23 year old Trademark doors & windows.
The latest products are a great improvement.
Thank you very much to everyone involved.
Best wishes, Angela & Colin.

Recently had a new back door installed by 5 Star. Great job. Totally satisfied.

We've had Premier Windows and Conservatories previously to fit new windows, doors and conservatory roof to our house at different times over the last 25 years, always with brilliant service.
We now needed 2 new windows in the garage to replace old rotten wooden ones and to replace an old sash window which hadn't been done previously as it is internal to the house due to the conservatory.
We didn't even look elsewhere as we have had such good service in the past. The quoting process was excellent with really good advice about the best way to replace the sash window. The wait time for fitting was not too long (and was even sooner than quoted).
On the day of fitting, the guys arrived on the dot and got cracking straight away. Dust sheets were put down to protect carpets (and even a dust sheet at the back of the garage). The job was completed to a very high standard and everything cleaned up and all rubbish taken away.
The result was better than expected - especially the sash window replacement which we weren't even sure about having done.
Cannot recommend this company enough.

Entire house fitted with windows less than a year ago, overall they seem ok, but its the after-sales service that you need to watch out for.

Ecofit wont transfer the warranty to a new homeowner, which makes it a limited warranty, not the impressive guarantee that they celebrate in their paperwork. Interestingly, they will also not honour the warranty with the original homeowner if they move out of the house - in our situation, we are in touch with the original homeowner, but Ecofit refuse to honour the warranty, even if the original homeowner was to request the repair.

This was told to me with delight by the receptionist who very quickly resorted to this line almost immediately after our phone call started. One might wonder why a business would offer such a 20 year guarantee, but seek not to honour it at all if the home changes hands; it became clear why this was later on.

One of the handles on the windows we have has come loose - the paperwork states the windows were fitted in June 2024, 4 months before we took ownership of the house, since when the window hasn't been opened until the summery weather began a few weeks ago. During the conversations with the business, not only did they advise the warranty was non-transferable; the contracted party (the previous owner) could not claim on the warranty; but a handle coming off less in less than a year was not an installation or a manufacturing fault, and was not coverable at all; the owner claimed if a handle has come off then it must have been exposed to extreme trauma and there was no possibility it could have happened otherwise (not that they were willing to come and investigate). They also refused to give me information on the part to seek my own replacement.

All-in-all I would recommend if you are looking to have these cowboys install your windows, be confident that they've done a good job from the outset because from the sounds of it they know their windows are fallible and will use any excuse they can find not to honour their guarantee. From their website: "We have total confidence in our products and installation skills, and the length of this guarantee proves that." The truth is, they can offer a 20 year guarantee because they have no intention of actually honouring it and will seek any opportunity to escape it that they can.

I did attempt to resolve this with the firm before writing a review, but they simply ignored it and never replied.

Their commitment to the Glass and Glazing Federation's Ethical Code of Practice it seems are only skin-deep, and the Consumer Protection Association membership must come in a cereal packet because it certainly seems that there's no willingness to uphold these concepts in practice.

We had a traditionally built garden room attached to the back of our bungalow. The workmanship of all the tradesmen was exceptional and of a high standard. Everyone, including suppliers of equipment and materials, were extremely considerate and polite. We cannot praise this company enough as they had very limited access in which to achieve such a lovely spacious room. From initial enquiry to end of contract, administration was of a high standard. We can't thank them enough for our beautiful room.

New windows in cloakroom and attic fitted in an old farmhouse.. Very pleased with result. 5 Star were a pleasure to deal with in all aspects from start to finish. Very polite and professional staff. Prompt and clear communication at all times. Would definitely recommend and use again.

We approached 5 Star Windows to get some ideas for replacing an existing,slightly leaking, twenty five year old roof.We were very impressed with the choice offered and,although not the cheapest quote, we decided to proceed as we had heard some good reports about the company.
We were very impressed with the service, the staff and most importantly the finished product.
All completed within the given timeframe and to a high standard.
We will certainly use the company again when their services are required.
