Planning Permission & Building Regulations

Citywide Lofts takes the stress out of compliance — we manage the entire process on your behalf.

Planning Permission

Most conversions fall under permitted development and don't require planning permission. For larger projects like hip-to-gable, we handle the full application and liaise with local authorities.

Building Regulations

All loft conversions must meet UK building regulations covering insulation, fire safety and structural integrity. We work closely with certified inspectors throughout your build.

Party Wall Agreements

If your home shares walls with neighbouring properties, a Party Wall Agreement may be required. We help arrange agreements to keep your project on track and dispute-free.

Local Brighton Expertise

Our in-depth knowledge of Brighton & Sussex regulations, combined with established relationships with local architects and surveyors, means your conversion is always compliant.

Frequently Asked Questions

Everything you need to know about loft conversions in Brighton & Hove. Can't find your answer? Give us a call.

Most loft conversions in Brighton fall under permitted development rights, meaning planning permission is not required. This typically applies to Velux and standard dormer conversions. However, if your home is in a conservation area, is a listed building, or the conversion significantly alters the roofline, planning permission may be needed. We assess this during your free consultation and handle any applications on your behalf.
Timescales vary depending on the type of conversion. A Velux conversion typically takes 4-6 weeks. A dormer conversion usually takes 6-8 weeks. A hip-to-gable conversion can take 8-12 weeks. These timelines cover the full build — from scaffolding to plastering. We provide a detailed project timeline before work begins.
Yes — a loft conversion is one of the best ways to add value to a property. Industry estimates suggest a well-executed loft conversion can add between 15-25% to your home's value, depending on location and specification. In Brighton & Hove, where space is at a premium, this figure can be even higher.
A Velux conversion installs roof windows flush with the existing roofline — no structural changes to the roof shape. It's the least disruptive and most cost-effective option. A dormer conversion adds a box-shaped extension that projects from the roof, creating a vertical wall with a window. This gives significantly more headroom and floor space, making it the most popular choice for habitable rooms like bedrooms.
Costs vary depending on conversion type, size and specification. As a guide: Velux conversions typically start from £20,000-£30,000. Dormer conversions usually range from £35,000-£55,000. Hip-to-gable conversions tend to start from £45,000+. These are indicative figures — we provide a detailed, fixed quote after your free survey so there are no surprises.
In most cases, no. The majority of loft conversion work is carried out from scaffolding externally, with internal work only beginning once the roof is watertight. We work hard to minimise disruption to your daily life throughout the project.
Most lofts in Brighton & Hove are suitable for conversion. Key factors we check include head height (ideally 2.2m+ from floor to ridge), roof pitch, and available floor area. Properties with traditional cut rafter roofs are generally the most straightforward to convert. We assess suitability during your free no-obligation survey.
All loft conversions must comply with UK building regulations regardless of whether planning permission is required. Key areas include structural integrity, fire safety, insulation and energy efficiency, staircase design, and sound insulation. Citywide Lofts manages the full building regulations approval process and works with certified inspectors throughout the build.
