A loft conversion is the easiest way to add extra space to your house. If your family grows, your home needs to grow too. With a loft conversion you can add:

  • Extra bedrooms
  • Bathrooms
  • Home office
  • Or even a home cinema or gym!

If carried out by a professional company like ourselves the cost of your loft conversion should (at the very least) be added to the value of your property.

We specialise in Box Dormer, L-Shaped and Hip to Gable Conversions.  We can also provide Architects and Structural Engineers to assist your build, taking you from early design to completion.  We are proud members of The Federation of Master Builders and all our Loft Conversions are also covered by a 10 Year Warranty.

We don’t subcontract out to other builders, so you can be safe in the knowledge that all the tradesmen involved in your Loft Conversion are qualified, experienced and vetted by us.

As a small, family run business, you can be assured that we will be there throughout your build, easily contactable, and happy to discuss your on going requirements over the phone, email, or through our regular, scheduled, site meetings.

Frequently Asked Questions

How many bedrooms/bathrooms can I have in my Loft Conversion?

This depends on the type of house you have. Standard 1930’s, 3 bedroom homes, will normally achieve 1 bedroom and shower room. Victorian houses with an ‘outrigger’ part of the house will usually achieve two bedrooms and a shower room. If you would like to know what your home could potentially fit, please give us a call for your no obligation, feasibility survey.

Whats the average cost?

The cost can range from £28,000 – £50,000 +VAT. The cost will vary greatly depending on whats being included, in regards to Architects Drawing, Structural Engineers Drawings, Building Control Fees, Decorating, Tiling etc. For an example, for an average 1 bedroom, and shower room box dormer you can expect to pay between £35,000- £38,000,to a plastered finish, with clients supplying their own bathroom suite floor coverings, and tiling. For a 2 bedroom and shower room conversion you can expect to pay £41,000- 45,000 + VAT (again with with clients supplying their own bathroom suite and floor coverings, and tiling). Extra costs that are sometimes requested are re-roofing the existing roof, full decoration down to the front door, any other building works.

Do I need Architects or Structural Drawings?

SLK Services can provide full Architects Drawings for planning or certificate of lawfulness, and full structural engineers drawings. We can do this as part of a full package, where we take the job from the very start to completion.

How long does a Loft Conversion take to build?

This varies depending on the type of work being carried out. A standard Loft Conversion can take anywhere from 6-16 weeks. This will depend on whether dormers are being built, how many bedrooms are installed, if structural work needs to be carried out, and to the extent of the finish. At SLK Services we like to finish the job so it is painted, tiled in bathrooms, floors down, its habitable and ready to move in. Some companies will only complete to a plastered finish.

Do I need planning permission?

Usually no, the majority of Loft Conversions can be built under Permitted Development Rights. Mid terraced houses will usually have a 40 cubic metre allowance, semi detached houses will have 50 cubic metres allowance. If you own a flat you will need planning permission. There are various other occasions where you might need planning permission, so its best to give us a call for a chat or check with your local councils planning department.
