Sound familiar?

Running out of space, but don't want to move?

Moving means stamp duty, agents' fees and leaving an area you like. Meanwhile the biggest unused room in most houses is sitting directly overhead.

The difference between a loft conversion that adds real value and one that disappoints is in the planning: the headroom, the staircase, the structure and fire safety. We work all of that out before you commit to anything.

See what my loft could be
  • Outgrown the house

    A growing family, a home office, or a guest room you simply don't have.

  • The cost of moving

    Tens of thousands in fees and taxes just to get one extra bedroom.

  • Unsure it's possible

    Not knowing whether your roof has the headroom, or which type of conversion suits it.

  • Worried about regulations

    Planning, building control, fire safety and party walls, all at once.

What's Included

  • Velux, dormer and hip-to-gable loft conversions, managed from design to final finishing
  • Structural work, insulation, stairs, electrics and plastering by one team
  • Building control handled, with party wall matters explained early
  • One loft conversion company from the first drawing to the final handover

Loft conversion in Swansea

Many homes in and around Swansea are older solid-wall properties, and coastal exposure makes wind-driven rain and damp a real consideration. Whether a loft suits a Velux, dormer or hip-to-gable conversion comes down to head height, roof pitch and the shape of the roof, and that varies street by street across Swansea with the age and style of the house.

What the survey checks

We measure head height at the ridge, check the roof structure and joists, and work out where the staircase can go without taking too much from the floor below. Swansea is covered by the same in-house team that works across the West Midlands, with surveys arranged around our regular South Wales work.

Planning and building rules in Swansea

Many loft conversions in Swansea fall under permitted development, within limits on added volume and where the dormer sits. Every conversion needs Building Regulations approval for structure, fire escape and insulation. Wales sets its own permitted development limits, so we confirm the route for your house before quoting.

We required an urgent new boiler installation due to the old one breaking down and being unrepairable. Greentek Energy supplied and fitted a new one at very short notice so our tenants could have heating and hot water again. We are very grateful to Greentek Energy and would recommend them highly.

What it costs

What a Loft Conversion Costs

The type of conversion drives the price far more than the floor area does. A Velux sits at the lower end, a dormer loft conversion in the middle, and a mansard at the top. We confirm what your roof allows before quoting anything.

  • Conversion type

    Velux, dormer loft conversion, hip-to-gable or mansard, in rising order of cost.

  • Structural work

    Steels, floor strengthening, and what the existing roof structure allows.

  • Stairs

    Where a compliant staircase can go, and what it costs the floor below.

  • Fit-out standard

    Whether the room includes an en-suite, and the standard of finish.

Every quote includes

  • A free site survey, with no obligation to go ahead
  • A fixed price agreed in writing before any work starts
  • Materials, labour and making good, in one price
  • Our own team throughout — no subcontractors marking the job up
  • A written workmanship warranty on completion

We don't quote over the phone from a postcode — the survey is what makes the price fixed rather than an estimate that moves. Finance is available through Ideal4Finance, subject to status.

Frequently asked questions

How much does a loft conversion cost in Swansea?+
It depends on the conversion type, the size and the structural work involved. We survey your Swansea loft, confirm what's achievable and give a fixed-price quote. Swansea is covered by the same in-house team that works across the West Midlands, with surveys arranged around our regular South Wales work.
What type of loft conversion suits homes in Swansea?+
Many homes in and around Swansea are older solid-wall properties, and coastal exposure makes wind-driven rain and damp a real consideration. Terraces often suit a rear dormer, semis a hip-to-gable conversion, and roofs with good headroom a simpler rooflight conversion. We recommend the type after measuring your loft.
Do I need planning permission for a loft conversion in Swansea?+
Many loft conversions in Swansea fall under permitted development within volume limits, but not all. Wales has its own planning rules, which differ from England's in places, so we check what applies to your Swansea address before quoting. Building regulations approval is always required, and we handle it.
How long does a loft conversion take in Swansea?+
Typically several weeks, depending on the type. Swansea is covered by the same in-house team that works across the West Midlands, with surveys arranged around our regular South Wales work. We'll give you a timeline with your quote.
Do you do loft conversions in Neath and Port Talbot?+
Yes. The same in-house team that handles loft conversions in Swansea also covers Neath, Port Talbot, Bridgend and Wrexham, with the same survey, fixed-price quote and workmanship warranty. See everything we do in Swansea.
