Most loft conversions typically fall between £30,000 and £60,000, depending on the size, type, and specific requirements of your home. Every project is unique, and the final cost really comes down to your design, layout, and the work involved.

There are several types of loft conversions — including Velux, dormer, and hip-to-gable — each with its own price range and structural needs. With over 25 years of experience, Glenn has delivered every kind of loft imaginable, so you can trust him to give you a realistic and transparent quote based on your exact vision.

Glenn is always happy to talk through ideas and tailor a design that suits both your home and your budget — no pressure, and no obligation.

The timeline for a loft conversion depends on a few key factors — including the size of the space, the type of conversion, and the layout of your home.

That said, most of Glenns loft conversions are completed in around 4 weeks, give or take a couple of weeks either side. More complex designs or larger builds may take a little longer, but he’ll always give you a clear and realistic timeframe from the start.

Every project is different, so the best way to get an accurate estimate is to book a site visit and consultation. Glenn will walk you through the process, answer your questions, and give you a personalised timeline based on your plans.

Glenn can typically begin building your dream loft conversion in as little as 4–8 weeks. This timeframe can vary slightly depending on demand, but in most cases — whether you're based in Thanet, or further afield in Kent — the schedule stays consistent.

If your plans, structural designs, and party wall notices are already in place, Glenn can move quickly. If not, you’ll want to allow around 2–3 months to get those sorted before construction begins.

Glenn offers a full design-and-build service, so if you need help with drawings, approvals, and paperwork — he’s got it covered. Already have everything ready to go? No problem — he's also happy to quote for the build-only phase.

Once Glenn has visited your home and completed the loft conversion survey, you’ll receive a detailed quotation within 7 working days by email. If it hasn’t arrived by then, be sure to check your junk folder — and feel free to give him a call just in case.

The good news? Your quote isn’t set in stone.

If you’d like to tweak the design, remove something, or add a feature you’ve seen in his past projects — that’s absolutely fine. He’s happy to revise your quote to suit your vision and budget, with help from your dedicated surveyor.

If your property shares a wall with a neighbour — either semi-detached or terraced — then a party wall agreement is usually required before starting your loft conversion. By law, your neighbours must be formally notified at least two months before any work begins using a party wall notice.

This agreement helps protect both you and your neighbours by outlining what will happen if any issues arise during the build. It ensures transparency and avoids disputes later on.

If needed, Gell can guide you through the process and connect you with a trusted, certified party wall surveyor to handle everything properly and professionally.

In most cases, you won’t need planning permission — as long as your property isn’t a flat or located in a conservation area, you likely have Permitted Development (PD) rights.

Under these rights, you can usually convert your loft without full planning approval, provided your design stays within certain limits:

Terraced homes: up to 40m³ of additional space

Semi-detached or detached homes: up to 50m³

If your design meets these conditions, you can apply for a Certificate of Lawful Development from your local council to confirm everything is compliant.

If your plans exceed PD limits or your home falls outside the criteria, you’ll need to apply for full planning permission — and we’ll guide you through that process too.

To meet building regulations in the UK, you generally need a minimum ceiling height of 2.2 metres (measured from the existing floor to the highest point of the roof).

This ensures there's enough usable space once insulation, flooring, and ceiling finishes are added. If your loft is just below this height, don’t worry — there are options like lowering the ceiling below or raising the roof, though these will require additional structural work and possibly planning permission.

There are several types of loft conversions available, including Velux (skylight), rear dormer, L-shaped dormer, mansard, hip-to-gable, and more — each suited to different property styles and space requirements.

Not sure which one fits your home? Our planning section and guide to loft conversion types break it all down, including which designs work best for terraced homes, Victorian properties, 1930s semis, and more.

🛏️ Master Bedroom with Ensuite

Create a peaceful, private retreat at the top of the house — ideal for growing families or just a little extra luxury.

🧒 Children’s Bedroom or Playroom

A fun, tucked-away space that keeps toys and mess upstairs and gives kids a room of their own.

🖥️ Home Office or Studio

Quiet, distraction-free, and filled with natural light — perfect for working from home or creative projects.

🛋️ Lounge or Media Room

An extra living space for relaxing, entertaining, or movie nights — especially popular with teenagers.

🧓 Guest Room

A welcoming, self-contained space for family or friends to stay comfortably.

🧘‍♀️ Wellness Room / Hobby Space

Whether it’s a yoga studio, reading nook, or craft room, a loft offers the perfect escape.

In most cases, a well-designed and professionally built loft conversion can add up to 20% to your home’s market value. It turns unused roof space into valuable square footage — whether that's an extra bedroom, ensuite, office, or living space and makes your home more appealing to potential buyers.

Not only do you gain more space without the stress of moving, but you also make a smart long-term investment in your property.

Great question! The choice between Velux (skylight) windows and a dormer loft conversion depends on your space, budget, and how you plan to use the room. Here's a quick comparison to help you decide:

🪟 Velux (Skylight) Loft Conversion

Best for: Simpler projects, good existing head height, and a lower budget

✅ Fits within your existing roofline — no major structural changes

✅ Typically cheaper and quicker to build

✅ Ideal for storage rooms, offices, or occasional guest rooms

✅ Less impact on external appearance

✅ May feel cosier, but space is limited by the sloping ceiling

🏠 Dormer Loft Conversion

Best for: Creating a full-height, spacious room like a bedroom or ensuite

✅ Involves extending the roof to create more usable floor space

✅ Adds headroom and light — ideal for bedrooms, bathrooms, or lounges

✅ Higher cost than Velux, but often adds more value to your property

✅ More flexibility with layout and furniture placement

In short:

Choose Velux if your budget is tighter or your loft already has good height.

Go for a dormer if you need maximum space, light, and comfort.

A site survey with a loft specialist (like Glenn!) will help determine which option suits your home best.

Yes, it is generally possible to have a loft conversion even if you have solar panels, but they may need to be temporarily removed and reinstalled during the conversion process. Glenn will need to assess the property for the best way forward. He can arrange for this process, or you can do it yourself.

In most cases, you don’t need a new roof to convert your loft. If your existing roof is in good condition and provides enough head height (typically 2.2m or more at the highest point), we can usually work within the current structure — especially with Velux or dormer conversions.

However, there are a few situations where a new or modified roof might be necessary:

🏠 Low head height – You may need to raise the roof or lower the ceilings below to create usable space.

🔨 Roof in poor condition – If the structure is damaged or worn, it might need repair or replacement anyway.

🧱 Complex layouts – Some larger or more bespoke conversions (like mansards) may require structural roof changes.

The good news? During your site survey, Glenn will assess the condition and structure of your roof and advise you on the best and most cost-effective option.
