Conservatory refurbishment cost
There are many different ways you can refurbish a conservatory. You may simply wish to give it a new look and feel, or you might want to convert your conservatory into a living space.
In recent years, homeowners realising the ease at which ageing glass or polycarbonate roofs can be replaced has seen a rising trend in conservatory refurbishment projects. Updating your conservatory roof can make all the difference and often sole the issue of the room being too hot in summer and freezing in the winter. The cost of updating your conservatory roof will be between £3,000-£5,000, although prices will be higher if you want a solid roof installed. The cost to refurbish the conservatory including the roof, window and walls will usually fall within the range of £4,000-£8,000.
Alternatively, you may want to reclaim the space entirely and turn the conservatory into a standard room in your home. As for the question of how much to convert your conservatory into a room, you’re looking at a price range of £5,000-£25,000 depending on your requirements.

- Location – As with all home renovation projects, costs will depend on location. Prices will usually be higher in the South than in the North of the UK.

FAQs
How much does it cost to have a conservatory roof insulated?
Polycarbonate and glass roofs may be visually pleasing, but they don’t add much in the way of thermal insulation. Adding layers of high quality, reflective film and thermal webbing will help transform your conservatory into a room you can use all year round.
The average cost for conservatory roof insulation including supply will sit between roughly £895 and £1,850 depending on the quality of materials and size of the roof.
Do you need planning permission to change a conservatory into a room?
Generally speaking, most projects of this nature won’t require planning permission. Since conservatories are typically located at the rear of the house, it won’t have an impact on neighbouring properties or nearby roads.
However, if you are planning to extend the conservatory space out into a bigger room, it’s best to apply for a Certificate of Lawfulness from the council to be on the safe side.
Is it cheaper to refurbish my conservatory than rebuild it?
The conservatory refurbishment costs will ultimately depend on your ambitions. In some cases, it can be as cheap to rebuild a new style extension than refurbish a conservatory.
If you’re making considerable structural changes, it may be worth asking your builder for a quote to rebuild rather than refurb so you can make a decision on the best route to pursue.
Can I refurbish a conservatory by myself?
Conservatory refurbishment projects require a lot of time and effort to complete. There are many parts of a conservatory refurbishment you can complete by yourself safely without much hassle. For more complicated refurbishments (glasswork, adjustments to foundations, carpeting), we recommend contacting a professional tradesperson if you have limited experience in home refurbishment.
A good conservatory refurbishment firm will take up any carpets or flooring carefully, take away and store and re-fit on completion rather than leaving it exposed to weather damage when the roof comes off.
