Cheltenham's mix of Regency terraces in the town centre, Victorian villas around Pittville and newer estates out towards Up Hatherley and Bishop's Cleeve means conservatory jobs here vary enormously. A wraparound extension on a period property near the Promenade throws up different problems, planning sensitivities, matching brickwork, listed building rules in the conservation areas, compared with a simple lean-to on a 1990s estate house near Warden Hill. Installers who work regularly in the area tend to know which streets sit in conservation zones, how local planning officers view rear extensions, and which roof styles cope best with the Cotswold weather rolling in off the hills.
The businesses listed here come from public business listings, and we've ranked them using review rating and the number of reviews each has built up, with a small boost given to those showing a working website and a contactable phone number. We also read through each firm's homepage to check that conservatory installation is genuinely their main line of work, not a sideline tacked onto general building or double glazing services, which keeps unrelated trades off this page. Listings that show as permanently closed get stripped out automatically. Where a business carries our Trust Verified badge, it means they've gone through our fuller check covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company details, and you can read exactly what that involves on our How We Verify page. Any business without that badge hasn't been through those checks by us, so it's worth doing your own homework before signing anything.
Before committing to a quote, ask to see evidence of FENSA or CERTASS certification for the windows and doors involved, and check whether the installer is Competent Person Scheme registered, since that affects building control sign-off. Get written confirmation of the base type, whether it's a dwarf wall or full glazed, and how they're handling the roof insulation, as thermal performance rules have tightened and affect what you can build without full planning permission. It's sensible to get two or three quotes for anything over £10,000, comparing not just the headline price but what's included, guarantee length and who's liable if something goes wrong with the base or the glazing seal.
How We Select & Rate The Best Conservatory Installers in Cheltenham
Ranking is based on review rating and review count pulled from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm conservatory installation is their primary trade, which filters out unrelated businesses. Listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have additionally passed our fuller 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 complete list. Other businesses on this page haven't been independently verified by us, and appearing here isn't an endorsement. Always carry out 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 Cheltenham?
A basic lean-to conservatory around 10 to 12 square metres typically runs from £8,000 to £14,000, while an Edwardian or Victorian-style build with a solid tiled roof can push past £25,000 once you factor in bifold doors and underfloor heating. Prices swing based on base type, glazing spec (double or triple glazed) and whether planning permission or building regulations sign-off is needed. Get two or three written quotes, since pricing between local installers can differ by several thousand pounds for a similar spec.
Do I need planning permission for a conservatory in Cheltenham?
Most conservatories fall under permitted development if they're single storey, don't exceed certain height and depth limits, and aren't at the front of the house. However, properties in Cheltenham's conservation areas, including parts of Pittville and the town centre, or listed buildings, often need full planning permission regardless of size. Check with Cheltenham Borough Council's planning department or ask your installer to confirm before work starts.
How long does it take to install a conservatory?
A standard lean-to or Victorian-style conservatory usually takes two to four weeks from breaking ground to handover, assuming no delays with groundwork or weather. Larger orangery-style builds with brick piers and a solid roof can take six to eight weeks. Ask your installer for a realistic timeline in writing and check what happens to the schedule if the base needs extra work due to clay soil, which is common in parts of the Cheltenham area.
What's the difference between a conservatory and an orangery?
A conservatory is mostly glazed, with a glass or polycarbonate roof and minimal brickwork, while an orangery has more solid brick or render walls, a flat roof with a central lantern, and usually feels more like an extra room than a garden room. Orangeries cost more, often £5,000 to £10,000 above an equivalent conservatory, because of the extra structural work and insulation needed to meet building regulations.
Will a conservatory add value to my house in Cheltenham?
A well-built conservatory that suits the style of the house can add value, particularly on family homes in areas like Charlton Kings or Leckhampton where extra living space is in demand. Poor quality installations or ones that look out of keeping with a period property can actually put buyers off, so matching materials and proportions to the existing house matters more than just adding square footage.
How do I choose between conservatory installers in Cheltenham?
Ask each installer for photos of completed jobs nearby, ideally ones you can go and look at in person, and request references from recent customers. Confirm they're FENSA or CERTASS registered for the glazing work and ask to see their public liability insurance certificate directly rather than taking it on trust. Check Companies House if they trade as a limited company, read recent reviews rather than just the overall star rating, and get everything, including the guarantee terms, in writing before paying a deposit.
