Recent Testimonials
Hello Jacky and team Just a short note to say ‘thank you’ for our new conservatory. We are delighted with the finished building and appreciate the trouble that you went to get everything absolutely right. All your workmen, particularly Darren and Josh, were very efficient and were a pleasure to have around (as long as gallons of tea were provided!).

Dear Cousins Just wanted to say thank you for the lovely bouquet of flowers you sent us on completion of our lovely conservatory. We are just laying a new wooden floor in there and look forward to using it over Christmas and the New Year. Please pass on to all staff concerned, our wishes for a very Happy Christmas and a Happy New Year.

A very good experience from first visit to show through to completion. Excellent attention to detail by Gavin, Jackie and Roger during quotation and specification. Similarly during installation by the two Daves work was carried out efficiently again with good attention to detail and finish. Cousins have transformed an old shabby conservatory into a bright modern living space.

Dear Cousins Having just received your guarantee document in relation to our new conservatory we’d like to say that we are very pleased with it. It has exceeded our expectations. The construction is excellent, the finish really good. We’d particularly like to commend your teams, Ian and Louis, LJ and his crew for their excellent work. It’s (almost) been a pleasure having them here, despite them drinking us out of tea and coffee and elder-flower cordial. So many thanks to you all for a job very well done.

Dear Sean and Sam Cousins did an excellent job on our new Summerhouse. The building size had to be adjusted for planning reasons due to the proximity of the boundary and this they managed very well. The groundworks were completed very well and with minimal mess.Finally the fitting team arrived the following week and meticulously put together the building with particular attention paid to the cedar shingle roof. They also painted any scuff marks that had occurred during the build at the end of the job. All in all an excellent building and well put together and at a competitive price. We would throughly recommend Cousins to anyone looking for a garden building or similar. Ours certainly looks beautiful.

Dear Sean We are delighted with the Summerhouse that you have supplied for us, very well made and constructed. The organisation at your end has been perfect and the people that you sent to do the work were really efficient and good humoured, a pleasure to meet. Your team had to carry all the items a considerable distance. The laying of the concrete base and construction of the building went so smoothly that at one point I began to wonder if I was dreaming.

We've always been impressed with our Cousins conservatory. We've had it for 11 years and it's the room we spend the most time in all year round. We've just had the roof upgraded to an ultra frame roofing system, ordered through and fitted by Cousins. The workmanship is great, the roof is fantastic: much better light levels, improved thermal performance (keeps the space cooler on sunny days and warmer in the colder evenings), looks great and is so much quieter than polycarbonate when it rains. We'd recommend Cousins, their products and their fitters very highly indeed.

Frequently asked questions
Affordability is perhaps the most important consideration for any homeowner. Conservatories vary greatly in price, starting at around £10,000 right up to over £100,000. Costs will be influenced by size, material, design, roof, glazing type, and site. It’s also worth visiting our vast show centre where we can give you guideline prices for models as displayed.
Usually the answer is no, as long as the conservatory does not cover more than half your garden area. There are exceptions, such as installing conservatories on Listed Buildings or in conservation areas, so, if you’re unsure, it’s always best to check with your local authority. Although planning permission is not usually required, your conservatory installation will need to comply with current Building Regulations.
When you’re planning a conservatory installation, it’s important to have a realistic timescale. This can help to limit disruption to your daily routine. Of course, timescales will depend on the size and complexity of the installation. A free survey will give you a general idea of what timescale to expect.
From Traditional style Conservatories to modern home Extensions, Orangeries, Loggias, and tiled roof conservatories, the choice can sometimes be overwhelming. By talking to an adviser and explaining your preferences, they can advise you on the best solution to your specific requirements.
Again, this will depend a lot on your personal preferences and the style of your home. As a general guide, PVCu is usually most cost-effective/thermally efficient and virtually maintenance free. Hardwood Timber is ideal for period properties and Listed Buildings.
Every home is different. The good news is that a range of conservatory styles will be available to you when you speak to us. We are able to tell you about the range of products available – for example, a Contemporary Lean-to conservatory is suitable for smaller homes – we offer advice on how to customise your product. For example, you could ask what colour schemes are available and whether you can add a wood-grain foil effect to the design.
