Insufficient head height assumed
Many homeowners assume their loft is suitable without a structural survey. Ridge height, roof pitch and steel requirements determine feasibility.
Loft Conversions
Unlock hidden space in your roof: bedrooms, offices, en-suites.
Loft conversions add significant living space without extending your footprint. We assess suitability, agree the layout with you and deliver a fully finished room.
What's included
- Structural assessment and steelwork if required
- Staircase design and installation
- Roof insulation and Velux or roof windows
- Plumbing for en-suites where requested
- Electrics, heating and lighting
- Plastering and decoration
- Building Control throughout
Structural works, fire safety, insulation and ventilation are signed off through Building Control.
The challenge
Problems homeowners face
Loft conversions unlock valuable space, but only when structure, regulations and finishes are handled correctly.
Wrong conversion type chosen
Velux, dormer, hip-to-gable and mansard each suit different properties. Choosing incorrectly wastes money or limits usable space.
Staircase compromises
Poor staircase placement steals room from existing floors. We design access that meets regulations without wasting space.
Thermal and fire standards missed
Loft rooms must meet strict insulation and fire escape rules. Non-compliant work fails Building Control and affects resale.
Disruption underestimated
Scaffolding, deliveries and structural work affect daily life. Without a clear programme, projects overrun and stress builds.
Our approach
How we solve them
We assess your roof structure first, recommend the right conversion type, and deliver a fully finished room signed off through Building Control.
Structural assessment included
We check ridge height, floor loading, roof type and steel requirements before quoting.

Regulations
Planning & Building Control
Planning Permission for Loft Conversions
Many loft conversions fall within Permitted Development, but dormers and mansards have size and position limits. We advise at survey.
- Rear dormers often permitted within volume limits
- Front dormers usually require planning permission
- Mansard conversions typically need full planning approval
- Conservation areas and listed buildings have additional rules
Permitted Development for Lofts
Permitted Development allows certain loft works without a full application, subject to volume, height and balcony restrictions.
- Volume allowances differ for detached and semi-detached properties
- Materials must be similar in appearance where visible
- Balconies and verandas are not permitted under PD
- We verify PD status before you commit to design
Building Regulations for Loft Conversions
All loft conversions must comply with structure, fire safety, insulation and ventilation standards.
- Floor structure must support new loading
- Fire-rated doors and escape routes to habitable rooms
- Part L thermal standards for roof, walls and glazing
- Staircase dimensions and headroom requirements
- Completion certificate issued before handover
Avoid costly errors
Common mistakes to avoid
Learn from the errors we see homeowners make — so your project runs smoothly from day one.
Not checking ridge height first
Minimum 2.2m at the ridge is a common requirement for habitable space. We measure at survey.
Choosing dormer before checking PD
Large dormers may need planning permission. We advise before design fees are spent.
Underestimating staircase impact
Stair location affects existing rooms. Early design prevents costly compromises.
Separating structure from fit-out
Integrated quotations avoid gaps between shell completion and final finishes.

Frequently Asked Questions
Is my loft suitable for conversion?
Most properties with sufficient head height (2.2m+ at the ridge) and adequate floor structure are suitable. We assess this at our initial survey.
What type of loft conversion is best?
This depends on your roof type — dormer, mansard, hip-to-gable or Velux-only. We recommend the most cost-effective option for your property and goals.
How disruptive is a loft conversion?
Most work happens in the roof space with scaffolding externally. We protect your home throughout and maintain clear communication on noisy phases.

Feeling Like Just Another Customer
Customer Completion Gift
A small thank you for choosing us.
A fantastic job done on my property by Kyle and team. Highly recommend them for all roofing and guttering jobs. Also would like to add the great communication from start to finish. Thank you!
Kyle and the team did a great job today of cleaning my garage roof from moss and then painting a polymer waterproof coating onto the roof. The manufacturers 10 year guarantee for a single layer makes it an easy choice for fixing water ingress into a garage. Time will tell, but I have high expectations. All the rubbish generated was taken away so very pleased.
Kyle and his team at Quality Roofing were great, punctual, communicative, and reasonably priced. They removed our old solar heating panel, replaced the felt and tiles underneath, and disposed of the panel, all in under 90 minutes. Great service from a reliable team.
Kyle arrived quickly to look at a problem we had with an old Velux. He quickly set about repairing it and it is now working fine. We really appreciate his quick service. Highly recommended.
