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 value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!

how much is a dormer loft conversion?

Are you considering a dormer loft conversion for your home? If yes, then you’d probably want to know how much it costs. Unfortunately, due to the several variables and influencing factors, a precise answer can not be provided for all dormer loft conversions. In this article we’ll give you a vague idea of the general cost so you can set a more realistic budget and start planning.

There are three main types of loft conversion which includes the Velux, Dormer, and Mansard. Out of the three types, the dormer happens to be the most common type and possesses a small flat roofed extension with a window. The dormer loft conversion will usually cost within the range of £25,000 to £30,000.

The price for a smaller dormer loft conversion, mid range dormer loft conversion and large scale dormer loft conversion will be at £2,000 to £7,000, £10,000 to £30,000 and £40,000 to £60,000 respectively. However, you should take note that the prices given are all based on varying influencing factors such as the type of installation that is selected, the type of the rood, en suite conversion as well as other customization. Changes in price can be as a result of the materials required and the extra time per labour that’s needed to complete this home improvement project by the tradesmen employed.

Furthermore, a dormer loft conversion average cost will also depend on the type of dormer you opt for. Here is a list of the most common applications:

✓ Blind dormer loft conversion - £3,200 to £4,400

✓ Recessed dormer - £1,300 to £1,850

✓ Barrel roof dormer - £3,000 to £4,600

✓ Gable dormer - £5,500 to £7,500

✓ Hipped roof dormer - £5,600 to £6,660

✓ Pedimented dormer - £12,700 to £23,100

✓ Flat roof dormer loft conversion - £13,800 to £21,600

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.
