Bespoke design rooflights

Beautifully crafted bespoke rooflights individually designed for your project

As the UK’s leading manufacturer of bespoke roof windows we are confident that you simply cannot buy a better quality product than a Lumen bespoke rooflight.

Unlike other companies, we don’t do upgrades. The reason being is that we can’t!

From the material frames, to the internal hardwood linings, high specification glazing and solid brass winding or electric opening mechanisms, we only use the highest quality materials available as standard.

We work with you to make your designs a reality

Lifting your designs from the two dimensional architect plans and turning them into a working product can be difficult. Our service is truly bespoke and you can work with us to produce rooflights to the size, shape and configuration that you want. Colours, glazing specification, interior timber choice and actuation can all be decided by you.

UK design, manufacture & assembly

We do it all here. Your project will start and finish in the UK; from your initial discussion about your requirements, through to your approval drawings, the production and the hand finishing. We are readily available via phone, email and live chat to ensure that we can help at any time throughout the process.

Lumen Heritage rooflights are designed, manufactured and assembled in the UK

No project too small

We pride ourselves on our approach to all projects and are as happy to produce one off small items as we are the larger projects. If you require something unique to suit your home, then we can help regardless of size or quantity.

A clear and simple process

We always aim to provide a written quotation on the same day as you request it. This will list out the requirements relative to each rooflight so you can understand exactly what you are getting for the price quoted. The quotation is provided without charge and you are under no obligation to accept. Should you wish to proceed with a bespoke order we require a 50% deposit of the total amount (inc VAT). You will then receive a confirmation via post. Once the deposit amount has been paid, our design team will produce an approval drawing for each rooflight on the order. This process can take up to 10 working days. Once your bespoke rooflight drawing/s are prepared we will send them to you via email for you to review. When you are happy that the drawing/s exactly match your requirements we need your written approval (usually via email) to move into the production stage. You are able to make as many changes and alterations to the drawings as necessary and we will not produce anything until you are happy for us to do so. The approval drawing is the final stage before the manufacturing process. Once you approve your drawing any subsequent changes will incur costs. If you do not understand your drawing please make sure that you speak to your builder or architect. The approval drawing will be the last document issued prior to manufacturing and will supersede your original enquiry or details shown on any quotation provided by us. If there is any discrepancy or error it will need to be highlighted as this point. If at any time you would like to discuss your drawing or query any information contained within it, please contact us via phone, email or live chat.


The manufacturing and finishes stages usually take around 6 weeks in total. This can go up and down depending on work schedules at the time of your order. Approximately one week before delivery we will contact you to discuss a convenient delivery date and take the balance payment. Your approval drawing will show you exactly how big your bespoke Lumen rooflights are, including the weights. Please ensure that you have adequate facilities on site to unload your delivery. Please tell us if there are any restrictions or difficulties that may hinder the delivery process. Most deliveries will be supplied by a national pallet network. Larger rooflights will not be able to utilise a tail lift so it might be necessary for you to have suitable equipment or manpower on site to unload. If you require specific delivery requirements or a dedicated vehicle, please talk to us. Your bespoke Lumen rooflight will benefit from the same comprehensive guarantee as all our Lumen rooflights.

Please note that all of our blinds, flashing kits, electric actuators and bespoke rooflights are manufactured at the point of order and are deemed to be special (bespoke) items. Bespoke items are non-refundable so it is important that you choose the right products when you order. If you are unsure or have questions, please contact us via phone, email or live chat to ensure that the product you are buying is right. In addition we take a 50% deposit on bespoke rooflight orders. Due to the work involved in producing these items, all deposits are non-refundable. Please refer to our current terms & conditions for full details. By placing an order with us, it will be deemed that you accept our terms & conditions.
In addition it should also be noted that whilst we are able to offer bespoke rooflights to any RAL colour, the silicones, tapes and rubbers will always be black. Please note that we are not able to accept returns of products that have been adapted or manufactured to customer requirements. In addition, we cannot refund deposits for work already started nor can we issue refunds for delivery costs, fixed standard sizes, electric actuators and flashing kits. We apply a 40% restocking charge to all stock items that are returned in the delivered condition and in the original packaging.

Our rooflights are available with a variety of electric actuator options. The actuators used are based on a number of factors including design and application. Not only do these drives provide the lift for the casement, they also provide the fixing (lock) when the casement is closed. The power of the locking is measured in Newton force (N). This can be converted approximately into kilograms and as an example, forcing open a drive with a 1000N force would be the same as lifting 100kgs (you would also need to factor in the casement weight).

The locking force of the drives we use is as follows:

KATO = 1700N
VCD = 2000N
KA34 = 1000N
KA54 = 1000N
KA66 (Twin Push) = 2000N
ZA85 (Pair) = 2200N


Unless otherwise requested by you, our delivery is to the site address only. Due to the sizes and weights of bespoke rooflights, the unloading and lifting process is the responsibility of the customer and the site team. The majority of bespoke designs cannot be unloaded by tail lift and it is therefore essential that you have the appropriate equipment and or people on site to unload. You will be provided with an approval drawing showing the weights and dimensions of each rooflight on your order to allow you to organise the necessary equipment. If you are unable to arrange your own offload, please talk to us and we can provide a quotation for additional equipment or manpower to assist on site.
