What determines how long a loft conversion will take
As mentioned in the previous section, a loft conversion timeline can vary based on several factors, each impacting the overall duration of the project. Here are the key factors that can affect how long it takes to convert a loft:
Type of Conversion: The type of loft conversion you choose can significantly impact the timescale of your new loft project. For example, a dormer loft conversion, hip to gable or a mansard loft conversion will take longer than a velux loft conversion
Size and Complexity: The size and complexity of the project will determine how long it takes to convert a loft. A larger and more complex project will naturally take longer to complete.
Structural Work: Any additional structural work required, such as reinforcing the existing roof structure or adding new support beams, can change the duration of the project.
Types of loft conversion
There’s a diverse range of loft conversion types available, each with its own unique features and style options. Some popular choices include rooflight conversions, dormer conversions, and hip-to-gable conversions, allowing homeowners to pick the one that suits their needs and preferences best.
However, it’s important to note that the suitability of a property for a loft conversion can vary widely. Whether you live in a bungalow, a two-story house, a terraced home, or a tenement, each type of property presents its own unique opportunities and challenges when it comes to loft conversions.
The key is to customize the conversion to the specific characteristics and layout of your property, ensuring a successful and functional loft space that enhances your house.
How long does a Velux loft conversion take?
The duration of a Velux loft conversion project can vary depending on several factors, including the size of the loft, the complexity of the design, and local building regulations. However, on average, a Velux loft conversion typically takes around 6 to 8 weeks to complete. Here are the main points to consider:
- Project Complexity: The complexity of your loft conversion design will play a role in determining the timeline. More intricate designs or structural changes may take longer to complete.
- Size of the Loft: Larger lofts naturally require more time for conversion, as there is more space to work on and finish.
- Planning and Permissions: The time required for obtaining planning permission and building regulations approval can affect the project timeline. Ensure all necessary permits are secured in a timely manner.
- Weather Conditions: External factors like weather conditions can impact construction schedules. Adverse weather may cause delays, so it’s important to account for this possibility.
- Contractor Availability: The availability of skilled contractors and tradespeople can affect the project timeline. Ensure that your contractors have a realistic schedule in place.

- Client Decision-Making: Efficient decision-making by the client regarding design changes or material selections can help keep the project on track.
How long does a dormer loft conversion take?
A dormer loft conversion follows a process similar to a Velux conversion but may require a bit more time due to certain factors.
Dormer conversions often involve a more complex design and extensive construction work, including structural modifications and roofing adjustments.
Obtaining planning permissions and ensuring compliance with building regulations can also be more intricate, adding to the timeline.
However, despite the extended timeframe, a well-executed dormer conversion can significantly enhance your living space and property value, making it a valuable investment in the long run.
Typical Phases of a Loft Conversion Timeline
When planning a loft conversion, it’s important to understand the estimated time frame for the project. A loft conversion can be divided into several distinct phases, each with its own timeline. Here’s an overview of the typical phases and their average length:
Phase Average Length
Design and Planning 2-4 months
Building regulations approval & Structural Assessment 2-4 months
Construction 6-12 weeks
Finishing Touches 1-2 weeks
The design and planning phase is where you’ll work with your architect or designer to create a detailed plan for the conversion, which will be submitted for approval. This phase can take anywhere from 2-4 months in total depending on the complexity of the project.
However, your loft conversion may not require planning approval – it may be permitted development if the conversion meets this criteria. (There are many different types of loft conversions)
If your project requires planning approval this generally takes around 8 weeks, sometimes less, sometimes more. It will depend on how busy the planning department is.
A building warrant or building regulations approval is required for every loft conversion across the UK, even the simplest conversion types. it’ll take around 12 weeks from start to finish to to obtain building regs approval.
In total allow at least 6 months to complete the design, planning, and building warrant.
It seems like a long time but it is worth taking time to ensure that everything is in order. when this is rushed mistakes can be made later during the construction stage.
Your home is often your biggest asset so it is worth protecting the value of your home.
The structural assessment and design phase will involve the structural engineer assessing the existing structure of the property and preparing design drawings for the conversion. This happens during the building warrant stage
The construction phase is where the actual work of the conversion takes place. This involves a range of activities such as removing the old roof, installing a new roof structure, creating new rooms, and adding insulation. Depending on the size and complexity of the project, construction can take anywhere from 6-12 weeks.
The finishing touches phase is where the final work of the conversion takes place. This usually includes activities such as decorating, laying flooring, and installing fixtures and fittings. This phase typically takes around 1-2 weeks to complete.
Keep in mind that these timelines are estimates and can vary depending on the specific requirements of your loft space. It’s also important to consider any unexpected delays or challenges that can arise during the conversion process.
How Long Does a Loft Conversion Take?
Now that we’ve discussed the factors affecting your loft conversion’s duration, let’s dive deeper into the step-by-step breakdown of the average timeline. Keep in mind that the following timeline is based on an average-sized loft conversion and may vary depending on the project’s size and complexity.
It’s important to be realistic regarding the time required to convert your loft.
During construction problems can occur which can delay the project, it’s best to allow a contingency for this.
1. Initial Design & planning permission (2-4 Months)
During this stage, you’ll work with your Architect to design & finalise the plans and designs for your loft conversion. This will include an initial site survey. Drafting the initial design and evolving this until you’re completely happy with this.
Once the design is finalised the drawings will be prepared to a standard that is suitable for a planning application. The planning application is submitted to the local planning department and we wait until a decision has been made – hopefully, the planning application will be approved!
A decision from the planners normally takes around 8 weeks (this fits within government target times)
If planning is not required we advise our clients to apply for a certificate of lawfulness (we apply for this on your behalf)
Once planning is secured (or the certificate of lawfulness has been approved) We move on to the next stage
2. Building regs approval & Structural Design (3-4 months)
The next phase involves submitting an application for building regulations approval or a building warrant to the local authority, at this stage, the structural engineer will be involved. The engineer will carry out his own survey of the property specifically focusing on the structure.
The structural design drawings and architectural plans will be submitted as part of the building warrant application.
Typically the structural design will focus on new support beams, bearing stresses, strengthening the floor, and updating the roof’s structure. The duration of this phase depends on the complexity of the project and whether or not any unexpected design issues arise.
Generally, an average loft will take 3 -4 months to gain building warrant approval.
You may also need a party wall agreement. (liaise with your neighbour about this)
Once the building warrant has been approved you can move on to the construction stage (carry out the loft conversion under building regs)
If any changes are made to the approved drawings during the build then an amendment to the warrant will be required.
Also if many changes are made during the construction phase then the timescale to complete it could go out the window!
All of these elements contribute to how long a loft conversion takes.
3. Construction – Structural
The first stage normally involves sorting out the structural changes that are required, doubling up joists and rafters, trimers for the stairs, installing steel beams, etc.
Depending on the contractor’s workflow, this generally needs to happen first.
An average full loft will take around 2- 4 weeks max for this, depending on the amount of structural modification required, if it’s a complex conversion it will take more time.
4. First fix Electrical and plumbing (2-4 Weeks)
During this phase, the first fix plumbing and electrical systems will be installed. This includes running cables for sockets and switchplates etc, Drainage and pipework will also be installed. To complete it could be around 2 – 4 weeks.
It’s important at his stage to know where all of the lighting, sockets, and switches will go as well as radiator positions, fans for ventilation etc.
5. Insulation and Plastering Second Fix Plumbing and Electrics (1-2 Weeks)
This phase involves insulating the walls and roof to ensure the space is energy-efficient and warm. After insulation, the walls and ceilings will be plastered to a smooth finish in preparation for painting and decorating.
During this phase, the fittings and fixtures for the plumbing and electrical systems will be installed, including showers, sinks, and light switches.
6. Joinery and Carpentry (3-6 Weeks)
This phase involves fitting doors, windows, and any bespoke carpentry, such as fitted wardrobes, cupboards, or shelving.
7. Final Fix Plumbing and Electrics (1-2 Weeks)
During this phase, the final touches will be added to the plumbing and electrical systems, including the installation of the boiler and radiators.
8. Decorating and Final Touches (2-4 Weeks)
During the final phase, the space will be decorated, including painting and laying flooring. The final inspection will take place to ensure that the project meets the building regulations, and any snags will be rectified.
Overall, the time to complete a loft conversion project can range from 14 weeks to 36 weeks, depending on the project’s complexity. Keep in mind that unforeseen circumstances can arise, resulting in delays, so it’s always best to be prepared for any unexpected issues.
