8 UK Companies to Buy Coxdome Rooflights From in 2026

If you have already decided on the brand, the next step is to compare where to buy Coxdome rooflights in the UK in 2026. Coxdome is a well-established name for flat roof daylighting, so the buying decision depends as much on stock range, delivery reliability, pricing clarity and ordering support as it does on the product badge. We considered five buying questions for each supplier: product range, delivery, pricing clarity, project suitability and ease of ordering. Published detail varies, so confirm any unanswered points before purchasing.

Our top pick is Addlite for buyers wanting a broad Coxdome range from a dedicated rooflight specialist, because it brings polycarbonate domes, flat glass variants and fixed, opening and electric formats together in one specialist catalogue. It covers residential and commercial requirements, with free or fast UK delivery depending on the product selected. For trade buyers who prefer direct support before committing, Trade Access Panels is a strong alternative. For buyers sourcing Coxdome Lumiglaze flat glass alongside other roofing supplies in a single order, Roofing Megastore is also worth considering.

The list below sets out eight UK Coxdome suppliers and the buying scenario each may suit, so you can narrow your options before checking the final specification and delivery terms. Whether you need a single residential unit or volume trade supply, there is a suitable stockist here.

What to Look For

When comparing Coxdome suppliers, consider these five factors and confirm any details a retailer does not publish. Start with range breadth: does the stockist list both polycarbonate domes and flat glass options, including fixed, manual opening and electric formats, so you can mix types in one order? Next, check delivery, including mainland UK coverage and whether the service is free or fast for your chosen product size, contacting the supplier about remote areas where the information is unclear. Look at pricing transparency and any stated guarantees, then consider whether the supplier fits your project, from a single residential flat roof unit to repeated commercial supply. Finally, assess ease of ordering, whether through online self-service, phone support or a trade account.

#1. Addlite – Best for Buyers Wanting a Broad Coxdome Range From a Dedicated Rooflight Specialist

Addlite is a dedicated UK rooflight specialist serving homeowners, self-builders and trade contractors who need to compare different Coxdome formats in one place. Its dedicated category for Coxdome rooflights brings together polycarbonate dome and flat glass options, including Lumiglaze variants, in fixed, manual opening and electric opening configurations. That breadth matters when a project mixes a fixed Coxdome Classic unit over a hallway with an opening rooflight over a kitchen, or an electric model over a hard-to-reach stairwell. For a UK flat roof buyer who wants to assess residential and commercial rooflight suitability without visiting several merchants, the specialist grouping keeps the specification work with one supplier.

Ordering is available online with no branch visit required, which suits both single residential purchases and repeat commercial orders of Coxdome rooflights. Delivery is described as free or fast depending on the product selected, so buyers should check the terms shown for their chosen size and format, then confirm coverage for remote postcodes before checkout. The presentation supports careful comparison of polycarbonate and flat glass products, kerb compatibility and ventilation choices, helping self-builders and contractors brief clients with more confidence. Buyers who need unrelated roofing materials may still require a second merchant, but the focused rooflight catalogue offers considerable choice.

Key Specs:

• Coxdome range covering polycarbonate dome and flat glass products, including Lumiglaze
• Fixed, manual opening and electric opening configurations listed together
• Specialist catalogue organised for residential and commercial specification
• Online ordering with free or fast UK delivery depending on the product
• Suitable for single-unit homeowner orders and multi-unit trade supply

Pros:

• Broad single-source selection across dome, flat glass, fixed, opening and electric products
• Specialist focus with clear grouping for side-by-side comparison
• Free or fast UK delivery depending on the selected product
• Suitable for residential one-offs as well as trade and commercial orders
• Online ordering without the need to visit a branch

Cons:

• No physical showroom for buyers who want to inspect a unit before purchase
• Not designed as a general roofing merchant for complete material orders
• The broad catalogue may take time to compare if only one standard size is needed

Who It Is Best For: UK homeowners, self-builders and contractors who want a wide Coxdome choice from one specialist supplier.

#2. Trade Access Panels – Best for Trade Buyers Wanting Direct Support and a Dedicated Coxdome Range

Trade Access Panels is a Cannock-based, trade-oriented supplier with a dedicated Coxdome rooflights category. Its offer is positioned for builders and maintenance teams as well as confident homeowners who already understand the basic specification they need. Buyers looking for a Coxdome Classic dome for a straightforward replacement, or comparing fixed and ventilated formats, can use the enquiry route and follow up during office hours. Customer reviews featured on the site provide another point of reference for first-time buyers assessing the company.

Ordering is centred on direct contact, with support available from Monday to Thursday, 09:00 to 17:00, and Friday, 09:00 to 16:00. That structure favours planned trade purchasing because sizes and kerb details can be checked in advance, although it is less convenient for evening or weekend enquiries. Confirm delivery availability and lead times for your postcode before committing, particularly if you are outside the Midlands. For Midlands contractors, dealing with a Cannock-based supplier may make communication and order planning more convenient.

Pros:

• Cannock-based supplier that may suit Midlands trade buyers
• Dedicated Coxdome category for focused product comparison
• Business-hours support for pre-purchase queries
• Customer reviews provide an additional source of purchasing reassurance

Cons:

• Support hours are limited, with a 16:00 Friday close
• The Cannock base is less local for buyers in Scotland, Wales or southern England
• No verified delivery speed or nationwide coverage details available

Best For: Trade contractors and builders who value direct advice alongside a dedicated Coxdome product category.

#3. Toughened Glass Systems – Best for Price Conscious Buyers Wanting a Stated Price Guarantee

Toughened Glass Systems is a London-based glass and rooflight supplier with a dedicated Coxdome rooflights category. Its search presentation carries a best price guarantee claim, which gives it a price-led proposition for cost-conscious homeowners and small builders. The Coxdome offer covers glass and polycarbonate formats, allowing buyers to compare a flat glass rooflight for a contemporary extension with a polycarbonate dome for a more budget-sensitive refurbishment. Direct sales contact also provides a route to clarify sizes and compatibility before purchase.

Online purchasing is supported by direct contact, which suits buyers who want to check specifications quickly without first opening a trade account. The best price guarantee should be read as the supplier’s commercial claim rather than an independently verified market test, so buyers should still compare like-for-like specifications, including the kerb, glazing and opening equipment. Check delivery timing, postcode coverage and trade account options before ordering. Buyers should therefore confirm delivery terms for their region and ask about pricing for larger orders where relevant.

Pros:

• States a best price guarantee for cost-focused buyers
• London base with direct support for pre-purchase queries
• Dedicated Coxdome category covering glass and polycarbonate products
• Specification questions can be raised before ordering

Cons:

• No verified delivery speed, coverage or trade account details available
• No showroom information was confirmed
• Limited public detail on the full range beyond glass and polycarbonate formats

Best For: Price-conscious buyers who want a stated price promise and access to direct support while ordering.

#4. Sterlingbuild – Best for London and Hertfordshire Buyers Wanting Local Merchant Support

Sterlingbuild is an established UK roof window merchant with business locations in London and Hertfordshire. Several contact methods are available, including phone, email and WhatsApp, giving trade buyers a practical way to raise questions from site. The company stocks Coxdome products through its brand section and serves homeowners and contractors who prefer a familiar merchant model rather than a rooflight-only catalogue. A buyer sourcing an opening rooflight for ventilation or a fixed unit for daylight can seek advice before placing an order.

Ordering can be discussed through several channels, although buyers should confirm the available purchase and fulfilment options for the exact product they need. The two premises may be useful to local customers seeking support, but collection or customer access should not be assumed without prior confirmation. Before ordering, check delivery prices and lead times for your postcode, particularly if you are outside London or Hertfordshire. As a generalist roof window merchant rather than a rooflight-only specialist, Sterlingbuild offers broader industry context, although its Coxdome range may be less extensive than a dedicated catalogue.

Pros:

• Business locations in London and Hertfordshire
• Multiple contact channels, including WhatsApp, for trade queries
• Established merchant presence familiar to local contractors
• Suitable for buyers seeking roof window and rooflight support from one company

Cons:

• Locations are concentrated in London and Hertfordshire
• No verified delivery speed or coverage details available
• Coxdome is part of a broader merchant range rather than the sole specialism

Best For: Buyers near London or Hertfordshire who value local merchant support and several contact options.

#5. INBUILD UK – Best for Trade Enquiries and Less Common Configurations

INBUILD UK, trading as Inbuild Online Limited, is a Kent-based independent merchant noted for trade supply and a broader choice of configurations. The company is listed as stocking Coxdome Classic alongside Pyramid and Circular formats, making it relevant where a project calls for something beyond a standard rectangular dome. Direct support is available for contractors who need to discuss several products or a repeated specification. For a trade rooflight brief involving multiple plots or commercial units, dealing with the requirement through one enquiry can simplify the initial planning stage.

Ordering for less common sizes and configurations is best approached through direct contact so availability can be checked. This suits experienced buyers but may take longer than an instant online transaction. The company’s online visibility is lower than that of some larger merchants, so buyers should request details of the current range and confirm the kerb, size and opening options in writing. Confirm delivery timing and coverage, and ask whether bulk pricing is available, before placing an order. South East trade buyers may find the Kent base convenient, while customers elsewhere can enquire when a particular configuration is difficult to source.

Pros:

• Reported Pyramid and Circular lines for less common project requirements
• Kent base may suit South East trade buyers
• Direct contact available for multi-unit or project enquiries
• Classic products are listed alongside alternative shapes

Cons:

• Full current availability may need to be established by direct enquiry
• No verified delivery speed or coverage data available
• No showroom or customer-access arrangements were confirmed

Best For: Trade buyers seeking information about Pyramid, Circular or other configurations that can be harder to find.

#6. Jupiter Blue – Best for Trade Accounts Needing Technical Support on Electric Opening Units

Jupiter Blue is a Yorkshire-based trade supplier with a service-led proposition built around technical support, bespoke sizing and fire certification documentation. The tagline “Proof, not promises” reflects its emphasis on documentation for commercial work. Its Coxdome information includes Classic electric opening formats, which may suit contractors fitting an electric rooflight where ventilation control, wiring and compliance paperwork need to be established before installation. The company is available Monday to Friday and states that it usually aims to reply within two hours, giving trade buyers a useful benchmark for weekday enquiries.

Ordering is consultative, with buyers encouraged to confirm dimensions, controls and certification needs rather than relying only on a self-service process. Any reference to next-working-day supply for electric units should be treated as a supplier claim and confirmed for the specific size and control option, particularly during busy periods. If drawings or bespoke sizes are involved, allow time for a weekday exchange and check whether the chosen unit can be ordered online. Northern England contractors may find the Yorkshire base useful, while buyers elsewhere should confirm delivery arrangements in advance.

Pros:

• States an aim of replying within two hours on weekdays
• Technical support and bespoke sizing for non-standard projects
• Fire certification documentation available for relevant applications
• Yorkshire base adds an option for Northern England buyers

Cons:

• Monday-to-Friday availability, with no weekend support confirmed
• Smaller independent supplier with a potentially narrower range
• No verified self-service online ordering route confirmed

Best For: Trade professionals needing technical advice and documentation for an electric opening specification.

#7. Rooflights & Roof Lanterns – Best for London Based Buyers Sourcing Classic Polycarbonate Domes

Rooflights & Roof Lanterns is a London specialist retailer with an active e-commerce presence and detailed product content for the Coxdome Classic polycarbonate dome line. That focus makes it a natural fit for buyers who have already settled on a Coxdome polycarbonate dome for a flat roof extension and want clear variant information before ordering. The company operates from premises in the Staples Corner area, but customer access is not available without prior booking. Its model is therefore primarily based on online purchasing and direct sales support rather than casual visits.

Ordering is available online with support for sizing and compatibility questions, which may suit South East homeowners and contractors working to a defined programme. Anyone who wants to visit should book first rather than travelling without confirmation. Check current lead times, delivery availability for your postcode and any trade account terms before completing an order. The range may be narrower than that of a full-spectrum specialist, but buyers focused on Classic domes may find the detailed product content easier to navigate.

Pros:

• London location may suit South East buyers and contractors
• Confirmed Classic polycarbonate range with detailed product pages
• Direct support available for ordering queries
• Active e-commerce presence with variant information

Cons:

• No walk-in access, with an appointment required for a visit
• Range may be narrower than those of broader specialists
• No verified delivery speed or trade account details available

Best For: London-area buyers focused on Classic polycarbonate dome supply with direct support available.

#8. Roofing Megastore – Best for One Stop Orders Combining Lumiglaze With Other Roofing Supplies

Roofing Megastore is a large online roofing merchant with a broad catalogue that allows customers to shop for a rooflight alongside other roofing products. Its Coxdome offer includes the Lumiglaze flat glass format, so a buyer specifying a Coxdome Lumiglaze rooflight for a modern extension can check whether the other materials needed for the project are available from the same merchant. Sales support is available for order enquiries, and office visits are by appointment only. This model may suit organised self-builders and contractors who know their schedule and want to reduce the number of suppliers involved.

Ordering is handled through an online retail model backed by direct support. It works well for planned purchasing, although the rooflight range is less specialised than a dedicated catalogue. Check the current delivery estimate and any trade terms at checkout, and confirm arrangements for large or fragile items. Office visits require an appointment and should not be treated as a walk-in service. For customers who prioritise consolidating purchases over having the widest possible Coxdome choice, Roofing Megastore remains a practical option.

Pros:

• Confirmed Lumiglaze flat glass option for contemporary flat roof designs
• Broad roofing merchant catalogue for buyers seeking other project materials
• Direct sales support available for order queries
• Established online retail presence for planned purchasing

Cons:

• Not a dedicated rooflight specialist, so Coxdome depth may be narrower
• Appointment-only office visits with no walk-in access
• No verified delivery speed, lead time or trade terms available

Best For: Buyers who want Lumiglaze glass and may also need other roofing products from the same merchant.

Frequently Asked Questions

What Is the Difference Between a Coxdome Polycarbonate Dome and a Coxdome Flat Glass Rooflight?

A Coxdome polycarbonate dome is a lightweight moulded unit suited to cost-sensitive replacements and projects where impact resistance and straightforward installation matter. A Coxdome flat glass rooflight uses a flush glass pane to create a contemporary, low-profile appearance and often suits living spaces where clear views and daylight quality are priorities. Thermal behaviour, kerb design and cleaning requirements also differ. Check the size, upstand compatibility and ventilation requirements before choosing between the two formats.

How Much Do Coxdome Rooflights Cost in the UK?

Cost depends on the size, glazing type and operating method, with fixed, manual opening and electric models priced differently. Kerbs, controls and delivery can also affect the final amount. Polycarbonate domes are usually positioned below comparable flat glass products, while electric operation and bespoke sizes add cost. One supplier in this list states a best price guarantee, but that remains a commercial promise, so compare identical specifications. For an accurate budget, request an itemised quote that separates the unit, any kerb, controls and delivery charges.

Which Coxdome Rooflight Is Best for a Residential Flat Roof Extension?

For most residential flat roof work in 2026, a fixed unit suits hallways and landings where daylight is the main requirement, while a manual opening unit can work well in kitchens and bathrooms where background ventilation helps control moisture. Electric operation is worth considering for high or hard-to-reach positions over stairwells. A UK flat roof buyer should confirm the internal reveal size, external kerb height and weather detailing with the supplier. If you want to compare all three operating modes through one company, start with a full-range specialist.

Can I Buy a Coxdome Electric Rooflight for a Commercial Project?

Yes, electric opening formats are available through UK rooflight suppliers in this guide, including specialists that work with trade customers. For commercial use, confirm the power requirements, control options, rain sensor behaviour and any fire certification documentation expected by the relevant building control body. Bespoke sizing may be offered where structural openings are non-standard, but availability needs to be checked. Allow time for technical checks and written confirmation of delivery, then retain the certification with the handover pack for future maintenance.

How Long Does Delivery Take When Ordering Coxdome Rooflights Online?

Lead times vary according to size, glazing and whether the unit is stocked or made to order, so there is no single UK delivery figure. Standard fixed domes may be quicker to despatch than electric or bespoke glass formats that require additional assembly. Check the current product information and confirm the postcode, access arrangements and delivery day in writing before booking follow-on trades. For remote areas, ask specifically about delivery terms and any additional handling requirements for fragile glass.

Do UK Coxdome Suppliers Offer Trade Accounts or Bulk Discounts?

Many suppliers in this roundup work with builders on repeat business, although formal trade account terms and bulk discounts are not always published. Possible arrangements vary by company and may include project pricing, staged deliveries or additional account support. To ask for suitable terms, share your schedule, total unit count and required configurations, such as Classic, Pyramid or opening models. Obtain written confirmation of any discount, delivery split and returns process so the site team can plan accurately.
