FAQs

Will I need planning permission to convert my loft?

Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.

how much is a loft conversion?

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?

Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.

✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.

✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.

✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.

✓ Hip To Gable Loft Conversion - This usually starts from £50,000.

how disruptive is a loft conversion?

Asides the questions relating to planning permission of a loft conversion as well as the total cost of completing a loft conversion project, this is perhaps the most common question on the loft conversion subject matter. Before making an investment decision, many homeowners will want to know just how disruptive a loft conversion is. Well, we’ve all heard the several horror stories when loft conversion builder with dirty boots tramples all over the fresh and just-acquired shag pile or the noise of the construction loud enough to annoy neighbours from four blocks away or an obvious shortage of teabags, sugar and lots more. Good news is, the disruption of loft conversion is not as bad as people make out. Let’s have a look at how it works!

Just like all other major building projects, a loft conversion is disruptive to your property. However, no two loft conversions are the same, therefore some are certain to be more drastic and invasive than others. In the long run, the project is worth the stress and inconveniences caused and in most cases, it’s usually a very good investment.

Normally, an average loft conversion is expected to last for about 9 to 12 weeks (depending on the complexity of the loft conversion project some might take longer). Some of the factors that affects the duration of a project includes the type of the loft, the design of the loft as well as the style of the property.

Generally, a loft conversion is a lot less disruptive than say completely moving a home. It all has to do with how you’re able to deal with it as a person. And besides, the effect it’s going to have to a large extent depends on the company you hire. A good company will always look to ensure to keep disruptions to a minimal when carrying out the loft conversion project.

how long does a loft conversion take?

If you’re about to carry out a loft conversion project, you’d probably be wondering how long it’ll take to complete the task. Well, you’re not alone! This is one of the most common questions when it comes to loft conversion projects, however, providing a set timeframe for completion of such projects is impossible as all loft conversions vary. There are different factors that can determine the duration of your project. These factors include, the materials to be used, the type of the proposed loft conversion, the kind of staircase you’ll like to have installed, the number of windows included, the number of rooms to be added as well as a number of other influencing factors. As a result of these variables, the milestones and timings provided are only to be taken as guidelines. If you’d really like to have a set date, you can get in touch with a professional for help.

Generally, it’ll take up to 8 weeks to complete a loft conversion project.

✓ The first week activities will include putting up scaffolding, receiving the first materials for the build and creating an opening in the roof to gain access to the loft space.

✓ In the second week, the structure of the roof will be ammended and more support added.

✓ Third week, the floor joists will be fitted, building of the loft conversion will start, completion of the external roof works and commencement of plumbing and electric works.

✓ Fourth week, complete the building, construct the loft floor, fit the roof windows, insulation, ventilation and internal stud walls.

✓ Fifth week, apply plaster and plasterboard to the room walls, create a staircase opening and fit the new staircase.

✓ Sixth week, plaster the staircase area, complete plumbing and electrical works, hang the doors, fit skirting, handrails and bannisters and start decoration.

✓ Seventh week, complete the decoration and clean and wipe out all wastes.

✓ Eight week, complete all the remaining tasks.
