The following words are very common and were not included in your search: how to

[google.com...]
There used to be a page on some seo site, might even have been here at the searchengineworld.com branch of WebmasterWorld, that topped 'how to' in the SE's and gave the example of 'how to' as 'unexpected' extra keywords you could optimize for. I'm not finding it with "how to" in double quotes, so it's probably been removed or replaced with a different example text.
Adsense, of course, is a somewhat different game than SEO, and it's possible that 'how to' will still get you placed, even though queries for 'how to' remove this phrase from the query.
I suppose they could be shoppers at the beginning of the shopping cycle but this product is also a DIY so they might want info how to do it themselves.

Stating the blatantly obvious though, I would be more inclined to target the rest of the question:
How can I rewire my home...
How to convert a loft
ad nauseum
Incorporating a solution to the question within the body copy would also prove attractive to me:
Loft conversion
