I tend to charge about £11 - £12 for basic 3 bed semi with no access hassles. I do still have 3 that I've been cleaning for years where I charge £8 (from before I slapped on my £10 minimum for new work). However, even with these £8ers, I can be taking 15 minutes from arriving to pulling away so it's hardly a disaster. If I pushed myself, I could probably maage in 10 or 11 minutes so long as thewre was no bird poo baked on anywhere. I just don't give them an elaborate service but it's certainly sufficient.
