After using this firm twice and giving them thousands I have to say I shan't be using them again complained to them about the chrome door handles peeling and a smug guy calling to see them I've not heard anything since, their loss having another firm to give a quote on a new conservatory Well this morning I had a call from Ambassador asking what had they done wrong, and I have to admit I was wrong putting this review on here, my issue was with the smug guy that called on us and not Ambassador the firm, I should have called them to complain about the guy so they could deal with him I've had good quality service in the passed from them I hope they will except my apology so again my fault not theirs.

Arranged for salesman to call out. Waited in all evening and he never turned up. Received a call from him the following day stating there was some other matter he was dealing with and his phone died. Really? Anyway, he then called another day, agreed a price, paid 400 deposit & was told 8 weeks for the door. 10 weeks later with no update I chase them up to be told we don't have it but it's due in next week.

Next week as you can imagine came and went, no door. Week 12 I chase them up again to be told it's been sent to another company and that it'll have to go back to the manufacturer to be checked who'll then send it to Ambassador to be checked and they'll the arrange to fit it. Week 14 the fitters turn up with a door that was the correct colour but a totally different design to what we ordered. The fitter was shown the order form as completed by ambassador & confirmed, it's not what you ordered & took it away with them.

So all this, they check it then we check it was all nonsense. After 14 weeks I demanded a refund which I did receive. The reality is that after 14 weeks my door had not been made or started as they made the wrong door! Not even an apology.

Rang for quote for two windows on 12/04/22, stating I was in a rush as was in middle of 2 bathroom renovations. Arranged visit for next day, when I accepted quote. Measurements taken the following day, Thursday. Then came Easter weekend. Tuesday 19th I was contacted and asked to confirm glass choice and windows fitted today, despite I'd not even paid deposit. All staff pleasant and helpful, actually arrive and ring back as arranged and workmanship second to none. Price not the cheapest but competitive with companies providing similar quality product. Highly recommend as my first choice.

We've just finished having all new sash windows installed and new doors. To say we are pleased is an understatement! The service and workmanship was exceptional. I highly recommend Ambassador Windows.

Absolutely brilliant service. The new windows and doors are superb quality and were professionally installed by a tidy, polite, competent team who took pride in their work and getting things right. We went with Ambassador after a previous conservatory we had from them. The Swish window units are rock solid and high quality. The after installation care is also excellent if there are any problems. Stay away from the cowboys, and ask Ambassador for a quote. The are highly recommended. Their prices are also excellent. The new Gray Windows and doors look very smart.
