Average Skylight Installation Cost
The average cost to install a skylight in the UK ranges from £800 to £2,500. Prices vary based on skylight type, labour and any extra materials used.
Factors Influencing Skylight Prices
Several factors affect how much someone pays for skylight installation. The main factor is size. Larger skylights cost more for both materials and labour. Shape is also important. Flat glass panes are often cheaper than domed or custom designs.
Glazing type is an important contributor. Triple glazing costs more than double glazing but will provide further insulation. Some brands offer extra features like UV protection, remote opening or rain sensors. These can also raise the cost.
Roof type can impact the price. Installing on a sloped or tiled roof might require more preparation and flashing than a flat roof. Flat roof skylight prices tend to be less than skylights on pitched roofs for this reason.
Cost Comparison by Skylight Type
There are 3 main types of skylights: fixed, vented, and tubular. Each type will cost different amounts. Below is a simple table:
| Skylight Type | Material Cost (per unit) | Typical Installed Cost |
|---|---|---|
| Fixed | £150 to £400 | £300 to £600 |
| Vented | £300 to £900 | £500 to £1,000 |
| Tubular | £200 to £500 | £300 to £800 |
Fixed skylights are the most budget friendly as they cannot open. Vented skylights open to allow airflow so they have extra hardware and are more expensive. Tubular skylights are smaller and work best for lighting small areas like hallways.
Large, motorised or custom skylights can cost more. Adding additional features such as blinds, tinting or sensors increases the installation cost.
Labour Costs
Labour accounts for a large part of the total skylight installation cost. Most installers charge £250 to £500 per skylight for standard jobs. This covers cutting the opening, preparing the site, installing the skylight and waterproofing the area.
If the roof structure needs support beams moved or additional reinforcements then labour costs can rise quickly. Roofers might need to match new parts with the existing roofing materials which takes more skill.
Some jobs take longer if internal work is needed. This can include work such as adding light wells or painting. Simple skylight installations take about a day whereas complex jobs could need two days or more. Labour rates depend on location with higher costs usually seen in London and larger cities.
Types of Skylights and Associated Expenses
Skylight costs can vary based on the type chosen. Installation, size and features also play a major role in determining final prices.
Fixed Skylights
Fixed skylights do not open or close. They are designed to provide natural light and are generally the most affordable type. Fixed skylights do not provide any ventilation.
Typical cost:
- Unit price: £150 to £400
- Installation: £300 to £600
These skylights are best for areas where ventilation is not needed such as hallways or stairwells. Simpler design means fewer moving parts and lower maintenance costs.
Advantages:
- Cost-effective
- Minimal risk of leaks
- Easier to install compared to ventilated models
Fixed skylights cannot help with moisture control in kitchens or bathrooms as they are permanently sealed. Most come in fixed sizes which can restrict placement options.
Ventilated Skylights
Ventilated skylights can open to let in air. This makes them a more versatile option. People often install them in kitchens or bathrooms to reduce humidity and smells.
Typical cost:
- Unit price: £300 to £900
- Installation: £500 to £1,000
They may include manual or electric opening options. Some models have rain sensors that automatically close the skylight when it starts to rain.
Advantages:
- Improved ventilation
- Helps control moisture
- Reduces condensation in damp rooms
Ventilated skylights cost more than fixed types due to the moving parts. They also require slightly more maintenance than fixed versions.
Tubular Skylights
Tubular skylights are smaller and designed to light specific spots, like small bathrooms, closets, or corridors.
Typical cost:
- Unit price: £200 to £500
- Installation: £300 to £800
A reflective tube guides sunlight from the roof into the space below. Installation can be easier and less disruptive as the tubes are smaller than traditional skylights.
Advantages:
- Great for small, dark spaces
- Lower heat gain and loss
- Minimal structural changes needed
They usually do not open so they do not provide ventilation. Instead they focus only on delivering natural light. Their discreet size makes them more adaptable in tight areas.
Skylight Installation Costs to Consider
The skylight installation cost often involves more than just the price of the unit and labour rates. Specific factors like changes in the roof, weather protection and additional features can increase the total cost of the project.
Roof Modifications
Adding a skylight can involve making changes to the structure of the roof. If the roof has trusses, rafters or other supports where the skylight is going, the installer may need to cut and reinforce framing. Older roofs might need extra work if the structure is weak or damaged.
Roof pitch and material affect costs as well. Tile and slate roofs usually cost more to modify than a concrete tiled roof. Flat roofs may need special types of skylights with extra drainage features. Removal of old roofing materials and debris disposal adds to the final bill.
Key points to consider:
- Structural changes can cost £200–£600+
- Special roof types (tile, metal, flat) may require added labour
- Waste removal fees sometimes run £50–£100
Weatherproofing and Insulation
Proper weatherproofing keeps water from leaking into the home. This often means installing flashing kits that channel water away from the skylight. Specialised sealants and waterproof membranes may also be needed.
Heat loss and condensation can be issues if the skylight is not insulated well. Quality skylights will include double glazing or tight seals. Sometimes extra insulation is added around the frame or in the roof cavity.
What to expect:
- Flashing kits typically cost £40–£150
- Sealants/membranes might add £20–£50
- Additional insulation could cost £50–£250, depending on the roof structure
Skylight Accessories
There are several optional accessories that can improve comfort and function. For example manual or electric blinds control the amount of light let into the space. Some skylights come with solar-powered remote controls. These of course add convenience but also cost.
Sensors that close the skylight when it rains are useful for certain types of roof windows. UV filters or tinting can reduce glare and protect interior furnishings from fading. Prices vary based on the brand and features selected.
Examples:
| Accessory | Typical Cost (each) |
|---|---|
| Manual blinds | £50–£120 |
| Electric blinds | £160–£400 |
| Rain sensors | £100–£200 |
| Bug/insect screens | £25–£70 |
| UV/tinted glass upgrade | £80–£200 |
Tips for Reducing Skylight Installation Cost
Careful planning and timing can help homeowners spend less on skylight installations. Skylight installation prices drop by choosing qualified installers and booking installations during quieter seasons.
Choosing the Right Installer
Comparing different installers is one of the best ways to lower costs. By getting written quotes from at least three local professionals it will be easier to see who offers the best rate and which services are included in the price.
Check if the installer is certified or recommended by skylight manufacturers. Certified installers are more likely to do the job right the first time reducing the risk of future repairs and extra costs. Always ask for previous customer reviews or photos of past projects.
Some installers offer discounts if multiple skylights are fitted at once. It may help to group jobs or coordinate with neighbours for a bulk rate. Avoid hiring anyone without insurance as mistakes could be costly if not covered.
