YES, Light Steel Framing is included in NHBC Standards and all NHBC projects which conform to the principles of NHBC Standards Chapter 6.10 receive an NHBC warranty.
NB: Some SHG members use Zurich and Premier for warranties that are comparable to NHBC.

YES, for instance, Barratt and Redrow have used Light Steel Framing on numerous schemes and have obtained acceptance from all major mortgage lenders. There are currently more than 10,000 steel framed homes in the UK which proves that it is not an issue.

NO, insurance costs are currently comparable with traditional construction. However, because of the ease and speed of repair, it is anticipated that, in the future, insurance costs will be lower than those associated with traditional. There is already evidence of this happening with Zurich in North America.

YES, relatively simple lintel conditions for new openings provide a more straightforward route for extension compared with propping, demolition and lintel insertion in traditional heavy construction.
Most ground floor windows in Light Steel Framed houses can be easily converted into patio type doors to gain access to conservatories for example. However professional advice should be sought before making any alteration to the property. As with all forms of construction, it is important to ensure that the integrity of the structure is not compromised.
Modular extensions can also be  added easily to some properties by using a volumetric supplier. These can be already fitted out internally together with service installations.
Equally, many light steel framing products are based on a simple wide span configuration, which gives freedom to also reconfigure the house internally.

NO, The steel frame is galvanised and normally comes with a warranty for use in its designed environment. The cavity between the frame and the external skin is drained and ventilated to minimise any risk of corrosion.

YES, there is no apparent reason why a metal framed house should be any less prone or more prone to lightning strikes and damage.

NO, there is no reason why a steel frame building would interfere with a radio or television signal more so than any other building construction type. The issue here is clearly as much to do with (i) absorption as (ii) reflection of a signal, both of which can damage the quality of a signal.
The reception of radio / TV or mobile phone signals obviously depends on geographical location as well as the reception systems used, but the same factors affect any building construction type.

YES, all forms of construction must meet the requirements of the Building Regulations, Part B. In light steel construction this is achieved by using fire-rated plasterboard linings. The number and thickness of boards is dependant on the fire rating requirements. Certified Systems have undergone testing and/or accreditation for fire resistance to prove compliance with the Building Regulations. Steel is incombustible and does not add to the fire load.

YES, there is no problem with putting up curtain rails or hooks etc as there is a range of proprietary systems available for attaching household objects to plasterboard which will easily support normal loads. Heavy loads can be screwed directly to the frame, which can be found using the type of hand held metal detector often used by plumbers.
