I do. The great things about A&A are:

- they don't assume you are a muppet
- they have no upload limits at all
- they have no evening download limits at all
- they have no weekend download limits at all
- you can carry your peak time download allowance or over usage over to the next month
- they give you as many IP address as you need
- they are good at badgering BT to fix things (and monitor all of their customer lines so they know there is a problem before you do)
- they give you access to all the stats that BT provide them on your line

Unfotunately they probably don't meet your cost and working at home requirements. Their peak hours, when the download limits apply, are 8am-6pm which is unlikely to fit well with working at home if you use a fair bit of bandwidth connecting to the office.

£22.97 + VAT will get you 3GB of peak download, £29.78 + VAT will get you 5GB of peak download. They are as reliable as any other ADSL ISP I have used (Plusnet, Easynet and Zen).
