Windows
We supply and install A+ rated uPVC, aluminium, and timber-effect windows with double/triple glazing. Our energy-efficient solutions reduce heat loss while maintaining aesthetic appeal, available in casement, flush sash, and sliding sash designs. All installations include a 10-year guarantee and come with optional integral blinds sealed within the glazing units for enhanced privacy and light control.
Doors
Our composite, aluminium, and bi-fold doors combine security with modern design. Featuring multi-point locking systems and thermal insulation, these doors enhance kerb appeal while meeting Secured by Design standards. We offer Origin Doors and Solidor composite options with customisable finishes and glazing patterns to match property styles.
Conservatories
We construct Victorian, Edwardian, and lean-to conservatories using premium uPVC and aluminium components. Our designs incorporate energy-efficient glazing and insulated roofs, with options for smart glass technology. All projects include a 10-year guarantee and meet building regulations for structural integrity and thermal performance.
hup! Extensions
Our hup! extensions use Ultrapanels for five times greater thermal efficiency than traditional builds. These off-site manufactured structures install in 3-4 days with minimal disruption, offering design flexibility for kitchens, home offices, or living spaces. BBA-certified for quality, they include A-rated glazing and meet Part L building regulations.
Roofline
We replace roofline components with durable uPVC fascias, soffits, and guttering in multiple colours. These low-maintenance systems prevent water damage, improve ventilation, and enhance property aesthetics. Installed with a 10-year guarantee, they feature bird-resistant designs and come with optional decorative finials and vented soffit boards.

I warn you don't use this company. Some of their fitters will ruin your installation. Ken Rhodes himself takes no responsibility. Our new windows were a complete mess and the doors still don't lock properly, as they are out of line. Two previous Instalations by two different companies were spot on. Ken Rhodes himself had the cheek to say my walls were out of line. Funny how the other companies had no problem.

Use them at your risk. He says in his reply he has no record of this installation. He probably has no memory that he spent two hours at my property and arguing in the street. He also has all the photos of the bad workmanship.

We had new windows, doors, conservatory and gutters/fascia/soffits done. All the work should have been completed by end of June but for various reasons got delayed and except for some snagging issues the works are only just complete 9 September! This has clearly been very stressful and we felt like we have only now just got our home back. Having said all of this I found Ken Rhodes (firm & owner) to be fair, reasonable and willing to see the job through.

If they got something wrong they would resolve it somehow. Overall I am happy with the work especially our new conservatory. We also had some new technology built into our windows which Ken Rhodes installed for the first time. Whilst this created some delays it is fairly unique. Special thanks to Dean, Gareth, Ross, Chris and Mick - pride themselves on quality. I feel if Ken Rhodes can improve their logistics and general customer service they will continue to maintain their fine local reputation. The issues with labour and building materials supply has clearly challenged all firms in the construction and allied trades industry.

I was given a quote, paid the deposit and was told i would have to wait 8 weeks for the installation. I was eventually given an installation date, took the day off work, waited at home and they never turned up, i was told i would have to wait another 8 weeks. I cancelled the installation and requested my deposit back.

This is by far the worst business I have ever dealt with in my life. The sales guy gives you all the lips service, " we are professional yaady daa nonsensical salesman talk", but when it comes to delivering on their contracts and actually being professional and honest there you find the real dishonest unreliable incompetent Kenrohdes management They stalled us with every excuse made up under the sun. 4 times they fail to deliver on agreed dates, 4 times the laying unreliable management come up with excuses I cannot fault the installers, good job they are contractors to them not part of them.

They caused so much stress and upset to us and so far no kind of professionalism or owning up or meeting their contractual delivery agreement Still waiting for my windows certificate Ken! If you need windows done avoid those pethatic excuse of company

I want to give a big shout out and thank you to the brilliant Service Eng who called at my mums this morning to rectify a problem with a door that was fitted at the end of January. He was professional, knowledgable, kind and helpful. Just a shame the same can't be said about the original fitting and rude and unfriendly Customer Service I recieved on the phone. Would I use Ken Rhodes again? Probably not!

No messing around, came out and gave us a reasonable quote in 5 minutes. We had quotes from others who started at twice the price and "haggled" down to a similar price. I happily recommended to my nan knowing she wouldn't be taken advantage of. Installation was quick and a really good finish. Only thing I'd change is the specifications we ordered got copied from one piece of paper to another when they measured up which makes it easy for mistakes. Had to give a ring to make sure it was all correct. A digital confirmation would be ideal.
