Planning your project
Time, cost and what to prepare.
What affects the time and cost
- The type of conversion and whether the roof shape changes
- Head height in the existing loft
- Where the new staircase can go
- Structural work to the floor and roof
- Adding a bathroom or en-suite
- Windows, insulation and fire safety requirements
Before you ask for a quote
- What the new room will be used for
- Photos of the loft and the landing below
- A rough measurement of the height at the highest point of the loft
- Whether the house is in a conservation area
- Any previous work on the roof
Rules in the UK
Permissions and regulations.
Many loft conversions count as permitted development, within limits: the extra roof volume is capped, nothing may rise above the existing roof, balconies are not allowed and materials should match the house. Houses in conservation areas, and flats, do not have these rights, so planning permission is needed there. See the Planning Portal guide to loft conversions and the general guide to planning permission (gov.uk).
Turning a loft into a habitable room always needs building regulations approval, covering structure, the new staircase, fire safety and insulation; see building regulations approval (gov.uk). In attached houses the party wall rules (gov.uk) often apply. A new loft room also needs ventilation under Part F; in an airtight loft, MVHR heat recovery ventilation is one option.
General guidance only, based on gov.uk and the Planning Portal. Your council or building control has the final say.
Things to watch
- Building regulations apply to every loft conversion that creates a habitable room.
- Changes to the roof, such as a dormer, can need planning permission.
- Semi-detached and terraced houses often need party wall notices.
- Bats are a protected species: if there may be bats in the roof, a survey can be needed first.

FAQ
Loft Conversions: your questions.
Do I need planning permission for a loft conversion in London?
Often not, because many loft conversions are permitted development. You will need planning permission if the work goes beyond the limits, for example a large dormer or one facing the street, or if the house is in a conservation area or is a flat.
Does a loft conversion need building regulations approval?
Yes. Converting a loft into a habitable room needs building regulations approval, which covers the floor structure, the staircase, fire safety and insulation.
What can my loft become?
An extra bedroom, a home office or a recreational space, customised to suit your needs.
Do you handle the whole loft conversion?
Yes. Our team handles the entire conversion process, from planning permission to building control sign-off, so you have one company to deal with.
Do you work with an architect?
Yes. We work with an architect and can help with this if your project needs it.
Will my neighbours need a party wall notice?
In a semi-detached or terraced house, usually yes: work on a shared wall is covered by the Party Wall etc. Act 1996, and notice must be given before it starts.
Do you give a warranty?
Yes. GONT LTD offers a 6-month warranty on its construction services. If an issue appears in that time, we come back and put it right.
