Examples of paperwork required include: Certificates of compliance/completion of works – evidence of building regulations being signed off by the local authority. Insurance and guarantee documents – from your loft conversion company, architect, builder and other professionals involved.
Most loft conversions are considered permitted development, which means you won't need to get planning permission as long as the building work fits certain criteria. So, if you're looking to get a simple conversion with roof windows, you generally don't need to worry (but it's best to check).
The first step involves determining if planning permission is required for the loft conversion or if the construction work can be completed under permitted development. We will be able to advise on this during the initial meeting with our design consultant.
If you are only carrying out internal works, planning permission is most likely not required. However, local interpretation can vary so it is important to have this verified. If you are planning on altering the roof space with an extension or dormer, planning permission would be required prior to beginning any works.
To help your loft conversion project run smoothly, ensure your loft is easily accessible. This includes clearing hallways and doorways to provide a clear path for the builders to manoeuvre through. Not only will this speed up the renovation process, but it will also ensure the safety of the workmen.
A basic loft conversion cost in the UK typically starts from around £20,000 to £30,000. However, more complex conversions or those with higher-end finishes can cost upwards of £40,000 to £50,000 or more. These costs are estimates. Get a local installer to QUOTE now!
In practical terms, you will need someone to provide architectural drawings for your loft conversion. You will need drawings for building regulations approval, and construction drawings for your builders to work from. But a good architect will do so much more than that.
Moreover, houses built during or after the 1960s may have trussed roofs, which are characterised by their 'W' shaped frames that support both the roof and the floor. These trusses are not designed with loft conversion in mind, as altering them is a complex process that requires replacement with sturdier supports.
Can you convert your loft yourself? Yes, but it depends on the project's complexity and your skills. Simple loft conversions like storage can be DIY, but more extensive work requiring structural changes or utilities usually needs professional help.
Absolutely. A loft conversion must be inspected and signed off by either local building control or an approved inspector to ensure it meets the building regulations.
A lot needs to be considered structurally, and the interior needs to be carefully considered to avoid problems down the line. Choosing to convert a loft without an architect's help comes with several risks, including: Poor design – this can lead to your house price decreasing rather than increasing. Planning refusal.
Lowest cost: A rooflight conversion that simply involves fitting out the existing roof space, requiring limited structural alterations and the addition of insulation, plumbing and heating, staircase, plaster and decoration, will be the least expensive option.
The timeline to complete loft conversions depends on multiple variables, including project size, type of conversions, and challenges faced during conversions. However, on average, a project can be completed in 6–12 weeks. The entire process of loft conversion is divided into different stages.
Your neighbours may reject your loft conversion plans due to noise, light, or privacy concerns, which will be taken into consideration by the council. If your planning permission is rejected, you can either appeal or amend your plans, keeping in mind the reasons for rejection.
Increases property value: Adding a loft conversion can increase the value of your home by 20% typically. This provides a good return on investment if you ever sell. Makes better use of wasted space: Most lofts are just used for storage. Converting it allows you to get more practical use out of the space.
Head height
Depending on the type of building you live in (and most likely, the date it was built), the minimum headroom required by law may differ. As a general rule, 2.2m from floor to ceiling at its highest point is the threshold for undertaking a loft conversion.
A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, provided certain limits and conditions are met.
Average costs for a small basic loft conversion can be as little as £13,000 to £20,000. A mid-sized loft conversion making space for a double bedroom with two windows would cost around £18,000 to £25,000. And average costs for a large double bedroom with an ensuite bathroom would be around £25,000 to £40,000.
A skylight (also known as a 'room in loft' or 'Velux' conversion) involves keeping the structure of the room as it is and simply fitting it out with better flooring, insulation, walls, and windows. This is the most budget-friendly conversion but does require you to have at least 2.1 metres of headroom available.
Converting your loft into a bedroom can be a great way to maximise space and add comfort to your home. Successful bedroom loft conversions, can increase the value of your property by up to 20%-25%. Your new bedroom must comply with building regulations to be signed off as a bedroom.
Loft conversion drawing costs range between £1,500 and £3,000. This includes initial consultations, the development of the concept, and the final detailed plans necessary for construction and any required approvals. The final cost can vary depending on the project's complexity, location, and the architect's experience.
A loft conversion is considered illegal if it was built without building regulations or planning permission. This may mean the conversion isn't safe for use or fit for habitation and unless it's rectified, the loft will be a potential risk to anyone living in the house.
Any construction work for a loft conversion will need to be signed off by local building control, with full documentation as evidence that your project has been carried out in compliance, even for permitted development.
