If you hire the experts we have at Loft Conversion London, rest assured that we will inform you of the process we’ll go through, detail to detail. Firstly, an area examination will be done. This is an important step because it will help us determine the available space where the conversion will happen. The square meter must meet the required measurement of your chosen loft type to ensure that you’ll get the space you want. Once the size of the area is set, plans for the loft conversion will be laid out. As we devise the plan, your opinions will be incorporated. The process concludes as we officially start with the construction of your loft in your house. Since we’re experts already in this kind of industry, you can conveniently check out how the loft conversion is being made and if it is being done accordingly to your plan.


The usual cost for a loft conversion starts at £25,000. You’re bound to spend only this much if you’ll opt for an internal loft conversion where construction only includes the installation of skylight windows and insulators. If you’re after a more substantial conversion, the cost may increase up to £95,000 depending on your chosen type of loft conversion.


Loft conversions take time to be completed because of how intricate their construction is. A loft conversion can take from 8 to 10 weeks to be built depending on how complicated your design goal is and how experienced the builders you will hire are. Acquiring our services at Loft Conversion London will have you experiencing undisturbed construction as we work with minimal disruption since we already have years of experience in converting lofts.


Yes, you do. For every construction that will happen in your home in St. James, getting a building regulation certificate is necessary. Having this in hand will imply that the construction that happened in your house has undergone proper safety procedures and is approved by the relevant authorities. This will also be a crucial document to present when you decide to sell your house later in the future because without this your property may be devalued as the loft cannot be considered habitable
