How much does a loft conversion cost in London?

The average cost of a loft conversion in London would be anywhere between £30k pounds and £75k pounds dependent on what type of loft conversion you want to have.

The price of a Velux or skylight conversion

One way to carry out our cost effective conversion of your loft is to consider a skylight conversion. This is probably the least expensive method because it does not alter the roofline structure. However what you gain in cost effectiveness you may lose in available space inside your new loft space. it will usually be possible to install a skylight loft conversion in most properties but this will depend on there being enough head height. The head height will be measured from the bottom of the ridge beam to the floor joists and needs to be a minimum of 2.2 metres. For a Velux conversion, Velux windows will be added to the conversion to maximise the light that comes in and this can be a great bonus in a smaller space. Cost for this kind of conversion, because again the structure of the roof does not need to be altered. with either the Velux or skylight conversion you will not usually need planning permission. Conversion can cost as little as £30k depending on the internal specifications and the size of the property in which the conversion is taking place

The cost of a dormer loft conversion

This is probably one of the most popular types of conversion and can cost from as little as £27k pounds up to around £50k pounds. The dormer loft conversion is what we would consider a mid-range price conversion but the big advantage it has is that it will be able to offer a lot more space. Where families are looking for more room this can be an ideal alternative to having to move house and will certainly add value to the property. This kind of conversion will also offer more headspace but you need to be careful if you live in a listed building or a property in a conservation area because special permissions will probably be required. We can advise you in all cases.

The cost of hip to gable loft conversion

This kind of conversion will normally cost anywhere from the low forty thousands to around £50,000, depending on the specification. The hip to Gable loft conversion price will vary depending on, of course, the size but also the internal specifications and the location.

The cost of a mansard loft conversion

the mansard loft conversion is often considered the elite and the most aesthetically pleasing of loft conversions and can give a stunning appearance to the exterior of the property as well as provide welcome extra space inside it. A mansard roof is categorised by its slope that needs to be of at least 72 degrees. Because this is almost a vertical slant the space within at the property is maximised. Mostly planning permission will be needed for a mansard loft conversion and this will depend on the nature and the size of any customised specifications that are needed.
