Oldham's mix of housing stock throws up some interesting challenges for conservatory installers. You've got Victorian terraces around Waterhead and Coldhurst with narrow rear yards, semis in Chadderton and Royton with more generous gardens, and newer estates out towards Shaw where plots are smaller but easier to build on. The Pennine weather doesn't help either. A good installer needs to know how to handle exposed sites near Saddleworth, where wind loading and rainfall matter more when choosing between a glass, tiled or polycarbonate roof. Local knowledge of planning rules matters too, since some streets fall within conservation areas where extensions need extra sign-off from the council.
The businesses listed here come from public business listings, ranked mainly by review rating and how many reviews they've built up, with a small lift given to those showing a working website and phone number. We read through each business's homepage to check that conservatory installation is genuinely what they do day to day, which stops general builders or unrelated tradespeople slipping onto the page. Any listing flagged as permanently closed gets removed automatically. Where you spot a Trust Verified badge, that business has gone through our fuller check, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page sets out exactly what that involves. Businesses without the badge haven't been through that process with us, so it's down to you to check those things yourself before signing anything.
Before committing, ask to see a FENSA or CERTASS certificate, since building regulations still apply to most conservatories, particularly around glazing and electrics. Get written confirmation of the roof type, glass specification and base construction, and ask whether the quote includes planning permission costs if your property needs it. Prices for a similar-looking conservatory can vary by thousands between installers, so getting two or three quotes is worth the time. Check what guarantee covers the frames, the roof and the workmanship separately, and ask how long the company has been trading locally, since that tells you something about how they handle problems after the sale.
How We Select & Rate The Best Conservatory Installers in Oldham
Ranking is driven mainly by review rating and review count pulled from third-party business listings, with a small lift for businesses showing a working website and phone number.

How much does a conservatory installers cost in Oldham?
A basic lean-to conservatory in uPVC with a polycarbonate roof typically runs from around £6,000 to £10,000, while a larger Victorian or Edwardian style with a tiled or glass roof can push past £18,000 to £25,000. Size, roof type, base groundwork and whether you need planning permission all affect the final figure. It's normal to get two or three quotes before deciding, since prices for similar specifications can vary quite a bit between installers in the Oldham area.
Do I need planning permission for a conservatory in Oldham?
Most conservatories fall under permitted development, meaning no planning permission is needed if they meet size and height limits. But properties in conservation areas, listed buildings, or those where the conservatory would cover more than half the garden, often need formal permission. Check with Oldham Council's planning department or ask your installer to confirm before work starts, since building without permission when it's required can cause problems later.
How long does it take to build a conservatory?
A straightforward lean-to on an existing patio base can take two to three weeks once the base is prepared. Larger builds with new foundations, or ones needing planning permission first, can take six to eight weeks from the initial survey to completion. Weather affects the schedule too, particularly foundation work in wetter months, so ask for a realistic timeline rather than a best-case estimate.
What's the difference between a glass, tiled and polycarbonate roof?
Polycarbonate is the cheapest option but can mean the room feels too hot in summer and cold in winter, plus it's noisier in heavy rain. Glass roofs with modern coatings regulate temperature much better and look smarter, but cost more. Tiled or solid roofs give the best year-round insulation and often let you use the conservatory as a proper extra room, though they're the priciest option and can need planning consideration depending on the design.
Will a conservatory add value to my house?
A well-built conservatory that suits the style of the property can add value, particularly on semis and detached houses in areas like Royton and Shaw where buyers expect extra living space. Poorly built or dated conservatories can actually put buyers off, though, so quality of build and how well it matches the house matter more than simply having one. Estate agents locally can usually give a rough idea of what's realistic for your street.
How do I choose between conservatory installers in Oldham?
Ask to see photos of completed jobs nearby, and if possible speak to a previous customer directly. Confirm the installer holds FENSA or CERTASS registration for the glazing work, and ask for proof of public liability insurance rather than just taking their word for it. Get a written quote breaking down materials, labour and any groundwork separately, and check what happens if the job overruns. Checking Companies House for how long the business has been registered can also give you a sense of stability before you commit.
