What is Velux Loft Conversion?

Velux loft conversion is one of the most popular types of loft conversion. It doesn’t require any structural alteration to the roof, it is affordable and it’s the least invasive loft conversion. It is the first choice for Brighton homeowners who want to have their loft converted.

A Velux loft conversion makes the most of your current space, increases natural sunlight in the room, makes it more habitable and doesn’t require planning permission to implement. It is ideal for the building where the loft has sufficient headroom but a small space, such as a study or single bedroom.

When compared to other types of loft conversion such as Mansard, Hip to Gables or Dormer loft conversions, Velux requires less construction, ensuring that it is not as disruptive as other types of loft conversions in Brighton.

Whilst planning permission may not be required, you should still check with the local authority in Brighton to ensure that you don’t need planning permission.

Our experts can provide you with free advice to get you past the planning process and ensure your loft conversion meets all the building regulations.

A rooflight window lets in plenty of ventilation and natural light to your Brighton home whilst retaining your privacy. You can use a blackout blind to prevent the room from being too warm in summer. It can also include a Cabrio system that turns your window into a balcony.

Types of Rooflight Windows

Fixed rooflights

A traditional design that is secured to an upstand on the roof. If you have a large window glazing area, several glass panes are joined to make one large rooflight. It offers great thermal performance and maximises sunlight to ensure the Rooflight doesn’t lead to heat loss.

Opening rooflights

This is a good solution for Brighton homeowners who are seeking more fresh air and increased ventilation for living areas below. These are electronically operated with a remote to provide an amazing combination of clean air and natural sunlight.

Walk-on rooflights

Just as the name suggests, you can walk on them. They are typically used in a garden or courtyard area that sits above a subterranean living space. It is a good way to increase natural light in the living area below. The glazing you use has to be strong enough to handle foot traffic have watertight performance and be completely safe.

Roof lanterns

If you’re looking to get great sky views or brighten up a dark space, then roof lanterns are the best option. They are designed to provide plenty of light, unrivalled sky views and an elegant style.

Sliding rooflight

A thermal-efficient sliding rooflight brings the outside in for increased ventilation and unobstructed light when slid into the open position. The rooflight supports its’ own weight without obstructive supports or roof tracks using a built-in telescopic sliding mechanism. It uses an electric motor and can be fitted with a rain sensor, remote control, temperature sensor and safety access control sensor.

Clifton Hill & Montpelier Loft Conversions only uses the highest quality Velux windows

We offer an impressive range of Velux windows to our Brighton customers who are considering a Velux loft conversion. The most desirable is the Velux smart window that does more than just let sunlight in.

These impressive windows automatically shut down when they sense that its’ about to rain and they open again to let in the sun. Adding a Super Sound Insulation reduces noise pollution by 50% for those who live in a noisy area. Our high-quality Velux windows ensure that your Brighton loft conversion is filled with natural light that complements the design of the room and makes it feel like home.

The benefits of roof windows in Brighton

High intensity, direct light

Sunlight is important for good health, and rooflight windows bring daylight directly to you. It is a part of the architecture that reduces energy for lighting and impacts cooling and heating loads.

This means your loft is more energy efficient when you install a roof window. The light from the sun enhances morale, reduces eyestrain and fatigue and leads to a positive attitude that lasts the rest of the day.

It is crucial that you use a good quality roof window to enjoy “first hand” proper light energy that is glare-free. Electric lighting is usually the best choice for Brighton lofts.

Great ventilation for Brighton homes

Ventilation in a building freshens up the air inside your Brighton home to maintain thermal comfort and good air quality. It also influences your psyche by creating a link to nature, the feeling of being in control and odour management.

Considering that many homeowners in Brighton spend a lot of time indoors, it is important to maintain the right context for healthy, fresh air to exist. The DEIC states that the quality of indoor air influences your mental performance and general wellbeing, makes you feel comfortable and prevents asthma caused by humidity.

Protect your loft from unwanted noise

Outside noise, especially for those who live in populated, urban areas has a negative effect on mood, health and learning capabilities. Noise can affect your well-being, cause mental fatigue, lower productivity and trigger stress. A well-insulated Velux window blocks outside noise makes you more serene and contributes to a relaxed sleep at night.


The opening and closing could either be automatic or controlled by an innovative bar at the top. Either way, it ensures you have a superb view when sitting or standing up and lots of natural light throughout the loft.


Most loft conversions get very cold in winter and too hot in summer. Velux windows feature ThermoTechnology which uses an airtight seal and excellent insulation to maintain an even temperature all year round.

Can I convert my loft?
Most lofts in Brighton are convertible but the only way to know for sure is to call Clifton Hill & Montpelier Loft Conversions for a free site survey. The most important thing to check for is the height of the roof. When measured from floor to ceiling, it should be at least 2.3 metres high.
How does a loft conversion add value to my home?
A loft conversion is an investment in itself. It creates additional room for a growing family. It can be used as storage, an extra bathroom, home office, kids’ playroom or bedroom. Building a loft with an en-suite bathroom could potentially increase the value of your Brighton home by up to 21%.
Who supervises my loft conversion project?

How do I obtain a quote?
You can call us directly on 01273 257450, send us an email or complete the online enquiry form and we’ll arrange a date that fits into your schedule for the free site survey.
Can I have a roof window if I live in a conservation area or listed building?
Designated areas include areas of outstanding beauty, national park, conservation area or World Heritage Sites.  You must apply for planning permission before a loft conversion in a conservation area. Considerations for permission include the height of the roofline, the impact on parking, the loss of light, privacy, noise and effect on nature conservation.

If you construct a loft conversion without a planning permission, your loft conversion is illegal and attracts a hefty fine of up to £10,000.

Can I carry out a loft conversion if I have a water tank in my loft?
Your water tank provides hot water that the occupants of your home rely on. If it’s located in the loft, you have several options.

The first option is to move the water tank to a corner. It frees up space and allows you to maximise your loft. A box in the tank hides the tank without affecting the aesthetics of your new loft conversion.

An unvented hot water cylinder is a great alternative to your old water tank. It eliminates the need for a cold water tank in the loft, so you save space. They can be located anywhere, including the basement.

The best option is to remove the old tank completely and replace it with a combi boiler. It takes up minimal room and is the ideal, long-term solution for maximising space in your loft whilst improving the pressure of hot water throughout the home.

Do I need building regulations for a loft conversion in Brighton?
The alteration, addition or removal of a rooflight can impact how the roof works. When making any improvements to the roof, it is crucial that you work with a specialist to ensure the roof performs as it should even after the conversion.

Building regulation is always required for a loft conversion. By UK laws, any structural modification to a building must comply with building controls that stipulate the standards for safety and design.

Do I need blinds for Velux windows in Brighton?
Roof windows increase natural lighting by 30% more than a standard window. If you require daytime shade, a suitable blind is essential. Most manufacturers offer blinds designed for their specific windows.

You are assured that Clifton Hill & Montpelier Loft Conversions stock both windows and blinds for your preferred rooflight window manufacturer. For example, Keylite’s window blinds reduce heat loss by 20% and some even improve thermal efficiency in your loft conversion.

How do I finance my Velux loft conversion?
There are many options to consider when planning how to pay for your Velux loft conversion. Re-mortgaging is popular with our Brighton clients. They take out a second mortgage on their home to fund their loft conversion.

The second option is the cash buyer programme where you pay for your loft conversion in stages from the date you signed the contract to the date when you receive the certificate of completion.

The third option is to leverage your savings if you have enough in the bank. If you don’t, you can put the rest on your credit card or look into a credit card cashback deal.

The final option is the “buy now pay later deal”. You pay 50% at the start of construction and the balance is paid over a period of 12 months. Alternatively, you could use the deferred and preferred method where the final 50% is spread over 60 months or 120 months.

What is a Velux window?
Velux is a type of rooflight window and the leading manufacturer in the UK. They have a reputation for quality that is unmatched by other manufacturers. Velux offers a range of window designs for Brighton homeowners who want a loft conversion that sheds light into the darkest corners of their loft, increases ventilation, makes their loft energy efficient and maximises available space.

Clifton Hill & Montpelier Loft Conversions uses high-quality Velux products that are inexpensive and durable. The faultless design, solid construction and quality materials gives a classic look to your loft.

How much is Velux loft conversion?
There are several things that affect the price of a Velux window. A few things include

  • The roof window size,
  • Centre pivot or top hung,
  • Manual, solar or electric,
  • Type of internal finish (white polyurethane, white painted or pine finish),
  • Type of glazing (extra noise redundant, extra low energy, comfort and safety)
  • Window flashing. Options range from EDW tile flashing to EDN recessed slate flashing

The most cost effective Velux loft conversion starts at £28,000 + VAT. The factors we mentioned above will influence the cost by as much as £1,000 or more.

Should I expect disruptions during a Velux loft conversion?
Velux loft conversion is a minimally invasive procedure. This means that you can go about your day without any issues. The process takes four to six weeks to complete.
Do I need a staircase for my Velux loft conversion?
Yes. Every loft conversion requires a staircase. The position of the staircase is one of the most crucial decisions. Our RIBA certified architects will advise you on the best position for your staircase, the design that best complements your loft and the general aesthetics of your Brighton home.

The ideal loft staircase maximises space in your home. A smart option is to install the loft staircase over the existing staircase. It creates a symmetrical design where one staircase leads to the other whilst saving space for your loft without affecting headroom. Clifton Hill & Montpelier Loft Conversions will design and build an amazing staircase for you.

Can I undertake a Velux loft conversion myself?
We do not advise DIY Velux loft conversion. The design process is especially tricky. You have to ensure that the building is strong enough to support the loft conversion and the design maximises space in the loft whilst sticking to Brighton building regulations. A poor design could endanger the lives of your family and those around you.

If you build a loft without getting the right permit, your loft is illegal and it loses any assumed increase in value. This makes it very difficult to sell your home when you want to move.

What is a party wall agreement?
A party wall is a shared wall between neighbouring houses, usually in a semi-detached or terraced house. It is the wall that divides both houses. A party wall agreement is needed for any building work that involves insertion of damp proof courses, loft conversions and digging new foundations.

You need a written party wall agreement signed by adjoining owners. A surveyor is appointed to prepare a Party Wall Award that states how work will progress. The adjoining homeowners have to be given two months written notice.

I have my own plans; can I use them?
We can use your own plans if that is what it takes to bring your dreams to life.
