Our Clients – Our Priority

We offer a bespoke professional service prioritising your needs… not ours!
Everyone’s needs are different so we treat you as an individual.

Our Expertise

SMA was established in 1996 as a specialist loft conversion company & since then, has been trading continuously under the same company name, directors & registration number (First 5 years as a partnership and subsequently as a limited company). Your conversion will be undertaken by one of our eight dedicated, non-subcontracted permanent teams. We never sub-contract out our work nor carry out work on another contractor’s behalf. In a transient industry, we are proud that our teams choose to remain with us, many for over 10 years.

Fixed Price Quotation

We only work to a fixed price quotation and our aim at the outset, is to capture the entire project specification as far as is possible. We clearly state what is included and, more importantly, what is not. We believe you should know the final cost of your project before you start your work… something our previous clients will happy attest to.

Guarantees & Insurance Liability ~ You’re Covered

We carry unlimited Employers’ liability insurance & £2million ‘All Risk’ public liability insurance to protect you whilst the build is in progress and a full 10 year, transferrable, warranty once the work is complete. We are members of the Federation of Master Builders, a Build Assure Warranty Registered company, able to offer insurance backed warranties. We are a (Government Backed) Trust Mark approved member and member of The UK Trades Confederation.

So why is SMA Lofts different?

Due diligence is the key ~ if you do your research, you will find that we are who we say we are!.
If you do your research, you will find we are who we say we are. Our reputation has been built on a long-standing, honest and transparent approach to quality construction. Our quotation will include a list of local client referrals ~ we urge you to make use of these to satisfy these claims for yourself. We take ownership & responsibility for your project!
