To save sending PM's individually to all, I'll post thie info, seing as others have also done so, without being removed by Admin.

We had ours done recently by a company called Loftlife. We have a 1930's semi. They have, apparently done several in our street over the years. As loft converters they were good, but beware of the sub-ccntracted specialist trades - the roofers were excellent, the plasterers good, but very messy (though I believe that's par for the course), but dear god their plumbers were abysmal.

I've also heard good things about the One Stop Loft Shop in Sydenham.

The Classic Loft Co. are also very active locally, but I've not heard them positively recommended. (As already mentioned by a previous poster). To a certain extent you get what you pay for.

Also, one of the companies we had a quote from wanted us to pay their builders in cash at the end of every week, from which we ran a mile!
