This question would be fine a year or so ago. Right now the question cannot just be answered as above. If you are in no rush and fancy trying selling, fine. If you want some immediate income then rent it. More and more building societies are pulling all their mortgages and the housing market is worsening because of this, not lack of buyers.
Also be aware, that in some areas, like mine, a further +/-100 houses each week are coming on the rental market.
Something else to bear in mind is how extensive are the renovations? Winter's coming. Does it have heating? Are you taking walls down? Plumbing being ripped out? If so you will need a bolt hole during the worst of it. Putting your current home on the market should at least enable you to live in it for a few months.
Suggest you hedge your bets. Put a sign up offering it as both a let and a sale.
