Worthing's housing stock throws up all sorts of conservatory jobs, from Edwardian terraces around Broadwater with tight side returns to the wider plots you get near Salvington and Findon Valley where a bigger orangery-style build is more realistic. Coastal exposure matters too. Properties closer to the seafront and Goring need installers who understand how salt air and wind loading affect uPVC and aluminium frames, and how flat roof lantern glazing holds up against driving rain off the Channel. A local installer will also know which conservatories need planning permission versus permitted development, which matters more than people expect given how many Worthing streets sit within conservation areas.
The businesses listed here are pulled from public business listings and ranked mainly by review rating and review count, with a small boost given to those showing a working website and phone number. We check each business's homepage to confirm conservatory installation is genuinely what they do day to day, rather than a sideline for a general builder, which keeps unrelated trades off this page. Listings flagged as permanently closed are stripped out automatically. Where you see a Trust Verified badge, that business has gone through our fuller verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. You can read exactly what that involves on our How We Verify page. Businesses without the badge haven't been through that process with us, so it's worth doing your own checks before you commit to anything.
Before signing off any quote, ask to see FENSA certification for windows and doors, and check whether the installer is registered with a competent person scheme for building regulations sign-off, since conservatories over a certain size or ones replacing an existing structure often need this. Ask what guarantee comes with the frames and the roof separately, as these sometimes carry different warranty lengths. Get at least two or three quotes in writing before you decide, and compare them on spec, not just price, because a cheaper quote sometimes means thinner glazing units or a lower-grade roof system. It's also worth asking previous customers in Worthing directly, if the installer can put you in touch, rather than relying purely on online reviews.
How We Select & Rate The Best Conservatory Installers in Worthing
Rankings on this page are driven by review rating and review count from public business listings, with a small lift given to businesses that show a working website and phone number. We check each business's homepage to confirm conservatory installation is genuinely their main trade, rather than a general builder taking on occasional glazing work. Listings marked permanently closed are removed automatically. Businesses carrying a Trust Verified badge have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information (see our How We Verify page for the full list). Other businesses here haven't been independently verified by us, and inclusion isn't an endorsement, so do your own checks before hiring.
Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

How much does a conservatory installers cost in Worthing?
A basic uPVC lean-to conservatory around 3m by 3m typically runs from about £8,000 to £14,000 in the Worthing area, while a larger Victorian or edwardian-style conservatory with a solid tiled roof can push past £25,000. Aluminium frames and bifold doors add to the cost, and orangeries with brick pillars and a lantern roof often start around £20,000 upwards. Ground conditions matter too, clay soil common around parts of Worthing can mean deeper foundations, which adds to the bill. Get two or three written quotes before deciding, since prices vary a fair amount between installers for what looks like the same spec on paper.
Do I need planning permission for a conservatory in Worthing?
Most conservatories fall under permitted development if they're single-storey, don't cover more than half the garden, and stay within height limits, but Worthing has several conservation areas, particularly around the seafront and parts of Tarring, where the rules tighten. If your property is listed or in a conservation area, check with Adur & Worthing Council's planning department before ordering anything. A decent local installer will usually flag this early and can help with the paperwork if it's needed.
How long does a conservatory take to build?
Once the design is agreed and any planning or building control sign-off is sorted, the actual build usually takes two to four weeks for a standard conservatory, weather permitting. Base and foundation work adds time if the ground needs digging out and concrete curing, so factor in a bit of a buffer. Larger orangery-style projects with brickwork and a lantern roof can take five to six weeks. Ask your installer for a realistic start-to-finish timeline in writing before work begins, not just a vague estimate.
What's the difference between a conservatory and an orangery?
A conservatory is mostly glass, with a glazed roof and thin frames, while an orangery has more brickwork, often a flat roof with a central lantern, and feels more like an extension of the house. Orangeries tend to hold heat better in winter and cope well with Worthing's damp, breezy winters, but they cost more and let in less natural light overall. Which one suits your house often comes down to the style of the property, a Victorian terrace usually suits a traditional conservatory better than a boxy orangery.
Will a conservatory need building regulations approval?
Not always. Conservatories under 30 square metres that are separated from the house by external-quality doors and have independent heating are often exempt from full building regulations. Once you start knocking through the wall for open-plan access, or if the conservatory sits over 30 square metres, building regs will usually apply. A competent installer registered with a scheme like FENSA or CERTASS can self-certify a lot of this work, which saves you dealing with building control directly, but always ask them to confirm which category your project falls into before work starts.
How do I choose between conservatory installers in Worthing?
Start by asking to see recent examples of their work locally, ideally something you can go and look at in person rather than just photos. Check they're registered with FENSA or a similar competent person scheme, and ask for proof of public liability insurance rather than taking their word for it. Read through recent customer reviews yourself, not just the star rating, to see how they handle problems if something goes wrong. Get a written quote that breaks down materials, roof type, glazing spec and labour separately, and be wary of anyone pushing you to sign on the day for a discount. Finally, ask how long they've been trading under their current company name, since that's easy to check via Companies House if they're a limited company.
