6 Best Roof Lantern Suppliers for UK Homeowners

When homeowners need to find lighting for an extension they will search for the best roof lantern suppliers near them and often struggle to identify the right source for their particular needs. In this article we offer a review of the six best roof lantern sources in the UK for homeowners renovating or building an extension. Read on to learn more.

A Review of the Best Roof Lantern Suppliers for Homeowners in the UK

A roof lantern can make a deep extension brighter and more inviting, but the frame, glazing and ordering route all need careful thought. Homeowners must compare more than appearance. Dimensions, thermal design, lead times, installation support and the difference between stocked and made-to-order units can all affect the finished project.

This guide ranks six roof lantern suppliers for UK homeowners, self-builders and contractors planning a kitchen, dining room or living-space extension. Addlite takes first place for buyers who want a made-to-order aluminium system with slim sightlines and a straightforward online route. EOS Rooflights is the most relevant alternative when a standard-size unit and a short stated turnaround are priorities. Aliwood Roof Lanterns offers another option for people who prefer the warmth of timber inside.

Before ordering, ask your builder to confirm the structural opening, upstand and drainage detail. You should also request the whole-unit thermal specification, glazing build-up, warranty terms and current delivery estimate from the supplier. These checks make it much easier to compare quotations on a like-for-like basis.

What to compare all the roof lantern suppliers before buying

Frame and glazing specification

Aluminium is popular because it combines strength with relatively slim profiles and requires little routine maintenance. A thermally broken frame reduces heat transfer through the metal, but performance depends on the complete unit rather than the frame alone. Ask for information covering the glass, spacer, frame and junction with the upstand.

The glazing specification should also suit an overhead application. Confirm the inner pane and available solar-control options and coatings, along with any requirements set by your designer or building control body. Do not assume that two products described as double glazed will perform in the same way.

Thermal performance

The roof lantern forms part of the extension’s overall energy calculation. Approved Document L, Volume 1: Dwellings provides the relevant energy-efficiency framework for work in England. Requirements and assessment routes vary with the project, so obtain the current product data and let the project designer or building control professional assess it in context.

A low headline glass value is not enough by itself. Ask whether the stated figure applies to the centre pane or the complete lantern. Installation quality also matters, while insulation around the kerb and effective air sealing will influence comfort.

Made-to-order or stocked sizing

A made-to-order lantern can match a planned opening and preserve the proportions intended by the designer. It is useful when the extension has already been designed around a particular daylight area or when standard sizes do not fit. The trade-off is that manufacture normally has to be scheduled before delivery.

A stocked unit may suit a simpler project with a standard opening and a tight programme. The builder must design the kerb around the actual product dimensions rather than relying on a nominal description. In either case, written confirmation of dimensions is essential.

Ordering support and documentation

A useful supplier should be able to explain how its quoted dimensions relate to the structural opening and upstand. Installation instructions, glazing information, maintenance guidance and written warranty terms should be available before commitment. Direct online ordering is convenient, but access to knowledgeable support remains valuable if the drawings are unclear.

Delivery and site handling

Roof lantern components and glass need safe access and dry storage. Confirm whether delivery is kerbside, how much notice the carrier provides and who must be present to inspect the consignment. Do not book installers solely against an estimated date. Wait for the supplier to confirm dispatch, then check the delivered items promptly.

1. Addlite

Best for made-to-order aluminium lanterns with slim sightlines

Addlite is the leading choice in this comparison for homeowners and trade buyers who want a focused aluminium roof lantern offer for a UK extension. It supplies made-to-order units through an online route, with a range centred on slim framing, thermal separation and project-specific sizing.

As a specialist roof lantern supplier, Addlite is particularly relevant to a single-storey kitchen or dining extension where the opening has been planned around a specific lantern size. The made-to-order approach allows the buyer and builder to coordinate the product with the structural opening instead of changing the roof around a limited stock list.

The focused range also makes the decision process more manageable. Buyers do not have to compare many unrelated systems before configuring a suitable unit. The company describes online ordering and support for homeowners and trade customers, which can help a self-builder who wants to purchase directly while still checking dimensions with a builder.

The route will not suit every buyer. Someone who needs an immediately available standard size may prefer a stock-led supplier. Addlite’s offer is also centred on an aluminium system, so people seeking hardwood or a timber-aluminium appearance should compare the specialist options lower in the ranking. Installation remains a separate responsibility and should be handled by a competent person following the product instructions.

Pros

• Made-to-order sizing for planned openings
• Aluminium system suited to contemporary extensions
• Online purchasing route for domestic and trade customers
• Specialist daylighting focus
• Slim-frame positioning for buyers prioritising glass area

Cons

• Less suitable for buyers wanting timber construction
• Made-to-order production requires programme planning
• Installation must be arranged separately
• Buyers should confirm current specification and delivery before ordering

Choose Addlite if you want a made-to-order aluminium lantern and prefer a focused online buying route.

2. EOS Rooflights

Best for standard units on a shorter programme

EOS Rooflights is a useful alternative where the opening can be designed around a standard unit. The company manufactures and sells rooflights, roof lanterns and skylights for domestic and commercial projects. Its published information includes a short delivery window for standard-size products, although buyers should confirm stock and dispatch dates for the exact unit before scheduling labour.

This route may appeal when a project is already on site and the contractor wants to avoid the longer programme associated with a one-off configuration. It also gives buyers access to a wider daylighting range if the extension needs a lantern in one area and a different type of rooflight elsewhere.

The available evidence does not provide enough detail to compare every thermal value, warranty term or glazing option here. Ask EOS for a current data sheet and written quotation. Check whether the relevant product is genuinely held as a standard unit or still requires manufacture.

Pros

• Standard-size option for time-sensitive projects
• Rooflight, lantern and skylight range
• Direct technical enquiry route
• Suitable for residential and commercial enquiries

Cons

• Short delivery claims must be confirmed for the chosen product
• Full thermal and warranty details require checking
• A standard size may not suit an opening already formed
• Bespoke lead times may differ from stock estimates

Choose EOS Rooflights if: your builder can work with a confirmed standard size and programme speed is important.

3. Stratus Lanterns

Best for manufacturer-direct aluminium enquiries

Stratus Lanterns offers a manufacturer-direct route for buyers looking for an aluminium roof lantern without using a broad home-improvement retailer. Its published offer focuses on made-to-measure supply, short lead times and competitive pricing, with clear relevance to trade customers.

A direct relationship can be useful when a builder wants to discuss dimensions and specifications with the producer. It may also suit repeat purchasers who already understand kerb construction and need a quotation based on drawings. Homeowners can still consider the company, but should establish how much measuring and installation guidance is available.

Published detail available for this comparison is limited. Buyers should request the whole-unit thermal value and glazing build-up, as well as colour choices, warranty terms and a drawing showing the relevant dimensions. Lead time should be confirmed in writing after the final specification is accepted.

Pros

• Manufacturer-direct buying route
• Made-to-measure positioning
• Relevant to builders and trade customers
• Aluminium system for contemporary work

Cons

• Technical detail needs direct confirmation
• Homeowner ordering support is less clear
• Warranty information should be requested in writing
• Stated lead times may vary by specification

Choose Stratus Lanterns if you are comfortable handling a direct factory enquiry and want an aluminium quotation based on project dimensions.

4. Prefix Systems

Best for broader glazed-roof and extension packages

Prefix Systems differs from the lantern-only specialists because its product scope covers glazed roofs, rooflights, solid-roof products and other extension components. That breadth can suit installers and builders who want to coordinate more than one part of an orangery or extension roof through the same manufacturer-led network.

A system-based approach may reduce uncertainty at junctions between components, particularly when the installer is familiar with the supplier’s details. It also gives trade buyers a broader set of options if the project changes from a fully glazed concept to a mixed or solid-roof design.

For a homeowner seeking only one lantern, the trade-oriented route may feel less direct than a simple online checkout. Availability can also depend on the installer or fabricator channel. Confirm who will provide the quotation and carry the warranty, and check which drawings apply to the proposed configuration.

Pros

• Broad extension-roof product range
• Relevant to installers sourcing coordinated systems
• Technical support within a manufacturer network
• Useful for orangery and mixed-roof projects

Cons

• Less focused on direct homeowner checkout
• A lantern is only one part of a broad catalogue
• Product-specific performance must be checked
• Supply may be arranged through a trade route

Choose Prefix Systems if: your installer wants to source a broader extension-roof package rather than an isolated lantern.

5. Aliwood Roof Lanterns

Best for a timber-aluminium appearance

Aliwood Roof Lanterns is the clearest choice in this list for buyers who want more warmth inside than an all-aluminium system usually provides. Its specialist offer combines timber character with external aluminium protection and concentrates on square and rectangular lantern forms.

That material approach can work well in traditional kitchens, period-sensitive renovations and interiors where visible timber complements cabinetry or roof structure. It provides a distinct design alternative instead of competing only on delivery speed or price.

The buyer should ask how the internal timber is finished and maintained and what colour and coating options apply outside. It is also important to establish how the complete unit performs thermally. Timber requires more consideration than a fully aluminium interior, particularly in rooms with changing humidity. Current size limits, lead times and warranty scope should be confirmed for the proposed design.

Pros

• Warm internal timber character
• External aluminium protection
• Specialist square and rectangular lantern focus
• Suitable for traditional and design-led interiors

Cons

• Timber needs suitable care and environmental control
• Narrower material and shape proposition
• Current thermal values require confirmation
• Made-to-order work needs programme allowance

Choose Aliwood Roof Lanterns if the internal material and character matter more than an all-metal minimalist look.

6. Tuck’s Wood Roof Lanterns

Best for bespoke hardwood craftsmanship

Tuck’s Wood Roof Lanterns serves a different part of the market from standard aluminium systems. Its workshop-led proposition centres on bespoke hardwood construction, with aluminium used for external weather protection on relevant designs. This can suit heritage properties and highly individual extensions where the lantern should resemble architectural joinery.

The quotation-led process allows the buyer to discuss proportions, finish and project requirements rather than choosing only from standard online options. That flexibility is valuable for unusual openings, though it also means more design work and a less immediate ordering process.

Request drawings, timber and finish information and glazing details, along with maintenance guidance, warranty terms and an agreed manufacturing programme. A bespoke hardwood unit is unlikely to be the best answer where low maintenance, rapid delivery or a tightly controlled budget is the main priority.

Pros

• Bespoke workshop-led service
• Hardwood character for period projects
• Scope to coordinate finishes with existing joinery
• Alternative to standard extruded systems

Cons

• Quotation required
• More maintenance than an all-aluminium interior
• Bespoke manufacture requires time
• Less suitable for price-led standard projects

Choose Tuck’s Wood Roof Lanterns if: the project calls for a distinctive hardwood feature and allows time for bespoke design.

Planning the design and installation

The lantern should be considered while the extension is being designed, rather than after the roof opening has been formed. Its dimensions affect the trimming structure, insulation, waterproofing and internal finishes. Early coordination also allows the designer to balance useful daylight against heat loss and summer solar gain while considering the visual scale of the room.

Ask for a dimensioned supplier drawing and have it checked against the structural plan. The builder must understand which measurement describes the structural opening and which describes the upstand or finished lantern. Nominal website sizes are not enough for construction. If the roof is already built, provide verified site dimensions instead of estimates.

Orientation matters as well. A large glazed area may receive strong sun at certain times of day, so discuss glass options, shading and ventilation with the project designer. A coating or solar-control specification may be appropriate in one setting but unnecessary in another. Avoid choosing an upgrade without understanding its effect on daylight colour, heat gain and cost.

Installation quality can determine whether a sound product performs well. The upstand needs to be square, level, insulated and correctly weathered. Fixings, seals and glass positioning must follow the manufacturer’s current instructions. The installer should inspect components before starting and should not improvise around missing or damaged parts.

Allow a realistic sequence for delivery. Large glass panels need suitable access and enough people or equipment to move them safely. Clarify whether the driver assists with unloading and identify where components can be stored. Protect finishes and glass edges until installation, retaining packaging labels and paperwork in case a problem needs to be reported.

Practical ordering advice when dealing with roof lantern suppliers

Start with a dimensioned drawing instead of a rough measurement. The supplier and builder must agree whether a dimension refers to the structural opening, external kerb, internal kerb or overall frame. Even a small misunderstanding at this stage can create expensive site alterations.

Next, obtain the complete technical pack. It should cover the glazing, frame and fixings, together with weathering and relevant performance information. Ask the building professional responsible for the extension to review it. Planning and building control are separate matters, and rules depend on the property and scope of work. General background on how permissions and building work interact can also be seen in discussions of loft conversions in the United Kingdom, although project-specific advice should come from the local authority or a qualified professional.

Then decide whether stock speed or a made-to-order fit matters more. A stock lantern can simplify procurement if the roof has not yet been formed. A made-to-order unit is usually more logical when the designer has already set the opening and proportions. Each route has its place.

FAQs About Roof Lantern Suppliers

Are made-to-order roof lanterns better than stocked units?

They solve different problems. Made-to-order products suit planned or non-standard openings and give the designer more control over proportions. Stocked units can shorten procurement when the builder is able to form the roof around a confirmed size. Compare the full specification and total programme, rather than looking only at the unit price.

What should I ask the roof lantern supplier for before placing an order?

Request a dimensioned drawing, whole-unit thermal information, glazing build-up and installation instructions. You should also obtain the warranty terms, colour confirmation, delivery conditions and a current lead time. Ask your builder to approve the opening and upstand dimensions in writing.

Does a roof lantern need building regulations approval?

A lantern installed as part of an extension normally has to be considered within the building regulations assessment for that work. Structural support and safety glazing may be relevant, as can thermal performance and weathering. Confirm the route with the project’s building control body before ordering.

Is aluminium or timber better?

Aluminium usually suits buyers seeking slim profiles and low routine maintenance. Timber provides warmth and traditional character but needs suitable finishing and care. Hybrid construction aims to combine an internal timber appearance with external aluminium protection. The best material depends on the architecture, available budget and expected level of maintenance.

How should I plan delivery and installation?

Confirm the dispatch date before booking labour and make sure there is safe access for unloading. Inspect the package promptly and store all components according to the supplier’s instructions. Installation should follow the approved drawings and product guide, with careful attention paid to the upstand, insulation and waterproofing.

Final verdict on the best roof lantern suppliers

When reviewing the best roof lantern suppliers for a property, Addlite is the strongest overall option in this ranking for a homeowner or builder seeking a made-to-order aluminium lantern through a focused online route. EOS Rooflights is a practical alternative for a confirmed standard size on a shorter programme, while Stratus Lanterns suits manufacturer-direct trade enquiries. Prefix Systems is relevant when the lantern forms part of a wider extension-roof package. Aliwood Roof Lanterns and Tuck’s Wood Roof Lanterns serve buyers who value timber character.

Shortlist your preferred roof lantern suppliers by project type, then compare drawings and written specifications rather than headline claims. The right supplier is the one whose product fits the opening, performance brief and programme, with an installation plan that leaves no unresolved assumptions.
