“Both Shaun and Carl were friendly and professional while fitting our new double glazed windows. They were thoughtful and tidy and cleared up behind themselves.”
“With so many window companies in the local area sometimes it can be hard to choose, but so glad we went with Admiral.”
“The two window fitters were very professional, hard working, cheerful and very polite, they also cleared up behind themselves at the end of the day.”
“…the fitters Andy and Nick were second to none. All mess cleared up and old windows taken away for recycling.”
“…they really do look like wood when viewed from the outside - but without all the hassle of having to paint them.”
“They have just completed a new-build property for me in Smart Aluminium and their knowledge and advice from product selection through to installation and care has been first rate.”
“The windows and doors are great looking product fitted with comfort plus glass which I recommend you pay the extra for.”

Why people pick Admiral over other window companies.
Four things customers mention again and again, in their own words.
-
Fitters you’ll know by name

“…no hard selling, just clear communication with no pressure.”
Lara Rodwell, Trustpilot, Jul 2023 -
Clean and tidy
Our fitters clear up behind themselves, and the old windows leave with them.
“The fitters Steve and Josh were really lovely guys. Very respectful of your property, clean, tidy and took great pride in how to fit the windows and doors.”
J Smith, Trustpilot, Aug 2026 -

- Whole house
“Ash and Jake are 2 genuinely nice guys with a wealth of expertise and fitted the whole house in 2 days to an excellent standard. Not only that the care and thoughtfulness they gave to cleaning up and looking after my house was so appreciated.”
Eve Dunn - Windows and doors
“Excellent product, very good quality UPVC windows and Aluminium doors. The value for money was really good and better than the 4 other local competitors we viewed.”
Adrian Leveridge - Victorian cottage
“Ours is a small Victorian cottage and although we at first wanted wooden windows to keep the cottage looking authentic we were persuaded to move over to the Admiral upvc ones as they really do look like wood when viewed from the outside…”
Lesley Hickman - Conservation area
“As we are in a conservation area they helped us with window selection and were very knowledgeable about what windows were required. The fitters were excellent and we were surprised how little disruption there was to each room.”
Mrs Hall - Comfort Plus glass
“The windows and doors are great looking product fitted with comfort plus glass which I recommend you pay the extra for. The installers were very friendly and professional, everywhere was left clean and tidy.”
Julian Pyke - One or two at a time
“…a quote well within my budget… the work was completed to a high standard. This was my 5th purchase, as I can only afford to do 1 or 2 windows at a time.”

How much do replacement windows cost?
Every window is made to measure, so the price depends on the size, style, frame and glass. We don’t guess from a photo: one of our own surveyors measures every opening for free, then you get a written quote to take away. If you’d like to spread the cost, finance is available at 12.9% APR representative.
Who will fit my windows?
One of our own surveyors measures every opening first, then Admiral’s long-serving fitting teams do the installation. Customers often name them in their reviews: Andy and Nick, Ash and Jake, Shaun and Carl.
Will you take the old windows away?
Yes. Our fitters take the old frames and glass out, clear up behind themselves and take the old windows away with them.
uPVC or aluminium: which is right for my home?
uPVC is the affordable, versatile, low-maintenance choice, and flush or woodgrain styles can pass for timber. Aluminium gives you slimmer frames, more glass and a crisp modern finish, and with the right detailing it suits older homes too. Both are A-rated as standard. Compare them side by side in our showroom, or ask at your survey.
Are your windows energy efficient?
Yes. All our windows are A-rated as standard, with triple glazing and acoustic glass available. In England, replacement windows must reach a U-value of 1.4 W/m²K or better, or energy rating Band B, and we confirm the rating of your windows, with the glass you choose, in your written quote.
I live in a period home or a conservation area. Can you help?
Yes. Flush casements and sliding sash windows are made to look like traditional timber, and your council decides what’s allowed in a conservation area. For listed buildings, where the original windows have to stay, secondary glazing adds warmth and quiet from the inside. We’ll tell you what’s likely to suit at your survey.
How soon can you fit them?
Every window is made to measure, so timing depends on the system, colour and glass you choose. We’ll give you a timescale with your written quote, and agree the fitting date with you.
Can I spread the cost?
Yes. Finance through Novuna at 12.9% APR representative, from £500 to £25,000 over 1 to 10 years, or buy now, pay later at 14.9% APR. Finance is subject to status. Try the calculator.
