What Does Each Package Include?
Basic Velux conversion - from £16,000
A Velux conversion is the simplest and most affordable option. We install roof windows (Velux or similar), add full insulation to walls, floor and ceiling, lay chipboard flooring, and board the space for storage or light use. An access hatch and fixed ladder are included. This is ideal if you want a usable storage space or a simple hobby room.
Standard loft room - from £22,000
Our most popular package. This converts your loft into a proper habitable room — fully insulated, plastered and finished. It includes a new fixed staircase, Velux windows, first-fix electrics (sockets and lighting), and a plastered finish ready for decoration. Building regulations sign-off is included.
Premium loft - from £30,000
Everything in the Standard package plus en-suite plumbing, an additional roof extension if needed, and a higher specification finish. Ideal for a master bedroom with bathroom or a self-contained suite.
Dormer conversion - from £38,000
A dormer adds a vertical extension to your roofline, creating full-height walls and much more usable floor space. This is the right choice for bungalows or properties where headroom is limited. It involves more structural work and usually requires building regulations approval.
Custom build - POA
Multi-room layouts, high-spec finishes, home offices with built-in storage, studio spaces. We quote these on a project-by-project basis after a free site survey.
What Affects the Cost of a Loft Conversion?
Several factors can move your final price up or down:
Property type. Bungalows typically cost more than standard semis or terraces because the roof structure requires more work to create usable headroom. Victorian properties with original roof timbers can also add complexity.
Roof pitch. A steeper pitch means more natural headroom and usually a lower cost. Shallow-pitched roofs may require a dormer to create a usable room.
Existing access. If there's already a hatch and basic boarding in your loft, we're building on a better starting point. No existing access means more first-fix work.
Specification. The finish level — flooring choice, window type, bathroom spec, storage solutions — all affect the final cost. We'll walk through your options clearly at the survey.
Structural requirements. Some loft conversions require additional structural steelwork, particularly in older properties or where a dormer is being added. We assess this at the free survey.
Do I Need Planning Permission for a Loft Conversion in Manchester?
In most cases, no. The majority of loft conversions in Greater Manchester fall under permitted development rights, meaning you don't need to apply for planning permission.
Exceptions include: properties in conservation areas, listed buildings, and conversions that significantly alter the roofline beyond permitted development limits.
We confirm planning requirements at your free site survey before any work begins.
How Long Does a Loft Conversion Take?
Most standard loft conversions take 4 to 8 weeks from start to finish. Dormer conversions and more complex builds typically take 8 to 12 weeks. We agree a timeline before we start and stick to it.
Is a Loft Conversion Worth It in Manchester?
Yes — a well-built loft conversion typically adds 15 to 20% to the value of a property. In Greater Manchester, where moving costs (stamp duty, legal fees, removals) can easily reach £20,000 to £30,000, converting your loft is almost always better value than moving to a larger house.
It's also significantly cheaper than a ground-floor extension in most cases, with less disruption to daily life during the build.
