Loft Conversion
Cost in Aberdeen.
How much should a loft conversion really cost in the North East? This is our honest, indicative price guide by type, from a Velux roof light to a full mansard, with a clear breakdown of what drives the figure and what is included.
How much does a loft conversion
cost in Aberdeen?
As a broad guide, most loft conversions in Aberdeen and Aberdeenshire fall somewhere between £45,000 and £65,000 and up, with the majority of completed projects landing in the middle of that band. A tidy Velux roof light scheme sits at the lower end, a dormer in the middle, and a hip-to-gable or mansard towards the top. Where your own project lands depends on the type of conversion, the size and shape of your roof, the finish you choose, and what we find once we get into the loft.
That is the honest version. Most pages will give you a single national average and leave it there, which is of little use when you are trying to budget for a real home in the North East. This guide breaks the cost down properly: by loft type, by what is and is not included, and by the factors that genuinely move the number. It is written for Aberdeen homes specifically, from granite terraces in the city to detached houses out in the shire, where older cut roofs, solid stone gables and the Scottish building warrant process all shape the final price.
Every figure here is indicative and meant for planning only. The single most reliable way to know what your loft conversion will cost is a free site survey followed by a detailed written quotation, which we provide with no obligation. For the full picture of the service itself, see our main loft conversions in Aberdeen page.
Indicative loft conversion
prices in Aberdeen.
Four common conversion types, four different starting points. The figures below are realistic guide prices for the Aberdeen area, based on the kind of work each type involves. Your roof decides which is right, and we will tell you which at survey.
Indicative only, subject to a site survey, and exclude VAT. These ranges reflect typical Aberdeen and Aberdeenshire projects and assume a single habitable room with a new staircase, insulation, windows, electrics and finishing. Adding an en suite, premium materials or complex structural work pushes the figure higher. We provide a detailed written quotation free of charge after a site survey, so the price you plan around is the price that holds.
What is included in a
loft conversion quote.
A cheap quote is rarely cheap by the end. The gap is usually in what was left out. When we price a loft conversion, the figure covers the full job, finished and signed off, not just the shell.
Structure
Steel beams, new floor joists, and any dormer or gable structure to carry the new room.
Warm & Watertight
Roof works, windows, full insulation to current standards, and making the space watertight.
Staircase & Services
A new staircase, electrics, heating, and plumbing for any en suite or storage you plan.
Finish & Warrant
Plastering, decoration, flooring, doors, plus building warrant liaison and completion sign-off.
Indicative only, subject to a site survey, and exclude VAT. A few items sit outside a standard quote unless you ask, such as bespoke fitted furniture, high-end sanitaryware, or upgrades to the wider home like rewiring beyond the loft. We set all of this out clearly in writing before you commit, so nothing arrives as a surprise on the final invoice.
Seven things that move the
cost of your conversion.
Conversion Type
The single biggest factor. A Velux scheme that works within the existing roof costs far less than a mansard that rebuilds it. Your roof shape often decides this for you.
Size & Head Height
More floor area and more structural change cost more. A tight loft that needs a dormer or hip-to-gable to become usable will sit higher than a generous loft that does not.
Roof & Structure
A traditional cut roof is generally simpler to convert than a modern trussed roof. Chimneys, water tanks and where a new staircase can land all feed into the figure.
Granite & Stone
Many older Aberdeen homes have solid granite or stone gables. Forming openings or a new gable in stone is more involved than in modern blockwork, and that shows in the price.
En Suite & Plumbing
Adding a bathroom or en suite means soil pipes, water runs and tiling. It lifts the cost, but it is also one of the surest ways to add value to the finished room.
Finish & Spec
Standard plaster and paint or bespoke joinery, fitted storage and premium flooring. The level of finish you choose can swing the final figure by several thousand pounds.
Building Warrant & Fees
In Scotland a loft conversion needs a building warrant, and most projects also carry design and structural engineering fees. These professional costs are real and we set them out plainly rather than hiding them inside the headline number.
The Unexpected
Old roofs sometimes hide rot, dated wiring or a structure that needs more support than the surface suggests. We survey thoroughly to limit surprises, and if something does appear, you hear about it and price it before we act, never after.

Is a loft conversion worth
the money in Aberdeen?
For many Aberdeen homeowners, a loft conversion is the most cost-effective way to add a room, because the space already exists above your head. You are not buying land or losing garden, and the cost per square metre is usually lower than building outwards. A finished, warranted loft room with a proper staircase, especially one with an en suite, is exactly the kind of space buyers value.
We will not promise a precise uplift, because the figure depends on your home, your street and the market on the day you sell, and we do not deal in invented statistics. What we can say plainly is that a quality conversion done to the building warrant, by an accredited builder, is far more likely to add lasting value than a cheap job that has to be revisited. The cheapest quote and the best value are rarely the same thing.
If you are weighing a loft against building out, it is worth comparing the two properly. Our home extensions in Aberdeen page sets out how a ground-floor extension compares on cost and use, so you can decide which route suits your home and budget best.

Loft conversion cost FAQs.
As a guide, most loft conversions in Aberdeen and Aberdeenshire cost between £45,000 and £65,000 and up. A Velux roof light scheme typically runs £45,000 to £50,000, a dormer £50,000 to £65,000, a hip-to-gable £55,000 to £65,000, and a mansard from £65,000 upwards. These figures are indicative only, subject to a site survey, and exclude VAT. The reliable way to know your own cost is a free survey and a detailed written quotation.
A Velux, or roof light, conversion is almost always the most affordable, because it works within your existing roof rather than rebuilding it. Windows are set into the current slope, so there is no dormer or gable structure to build, which keeps the cost down. It only works where you already have enough head height, so the saving depends entirely on your roof. We will tell you at survey whether a Velux scheme suits your loft or whether a dormer is the better value over the long run.
The conversion type is the biggest single factor, followed by the size of the room, the structural change involved, and the finish you choose. Aberdeen specifics matter too: forming openings in solid granite or stone is more involved than in modern blockwork, older cut roofs can hide surprises, and adding an en suite lifts the cost through extra plumbing. Professional fees for design, structural engineering and the building warrant are real costs as well, and we set them out plainly rather than burying them in the headline figure.
In Scotland a loft conversion needs a building warrant from Aberdeen City or Aberdeenshire Council. Our quotes cover liaising with the council and managing the application on your behalf, and we set out any associated design, structural engineering and council fees clearly so you can see them. We tell you exactly what is and is not included at quote stage, so there is no confusion about who is paying for what.
Usually because something has been left out. A low headline number often excludes the staircase, full insulation, finishing, or the building warrant, which then appear later as extras. We price the whole job, finished and signed off, in writing, so you are comparing like for like. If a quote looks unusually low, ask exactly what it includes. The cheapest quote and the best value are rarely the same thing.
Yes. You pay to a written schedule tied to agreed milestones, so you only pay for work that is completed and inspected, never a large sum upfront. For larger projects we can also introduce a regulated finance provider so you can spread the cost over time. We are happy to talk through the options at quote stage so the project fits your budget as well as your home.
