UK VoIP Call Costs Compared

As you might have seen from my recent tweets, I’m looking at changing my VoIP provider (I started off on Gradwell’s Multi User package, moved to VoipFone (which never really “worked right” with my setup) then moved to AAISP), as AAISP don’t currently offer all the facilities I would like (the most important one being sending the “number being called” as the CLI when forwarding VoIP calls to my mobile). But which one to go to? Well, after two long calls to o2 mobiles today, I started to look at call costs as well as the “monthly rates” – and here’s the details of the VoIP call costs and “line rentals” which may be of use to people:

Provider Monthly rate for 01/02 number Monthly rate for 03333 number Peak to o2 mobile Weekend to o2 mobile Peak to 01/02/03 numbers Weekend to 01/02/03 numbers
Gradwell Single User £4.00 £4.00 9.00ppm 6.00ppm 1.25ppm 1.00ppm
Gradwell Multi User £8.00 £8.00 9.00ppm 6.00ppm 1.25ppm 1.00ppm
AAISP £1.00 £1.00 18.33ppm 18.33ppm 1.25ppm 0.83ppm
VoipFone £2.00 £2.00 12.00ppm 12.00ppm 1.00ppm 1.00ppm
Soho66 £2.00 £2.00 10.00ppm 10.00ppm 1.00ppm 0.50ppm
VoIPTalk Standard Tariff £2.99 £2.99 11.90ppm 11.90pm 1.40ppm 1.40ppm
VoIPTalk Prepay Silver Package £6.98 £6.98 9.90ppm 7.90pm 1.00ppm 1.00ppm
DrayTEL Standard Tariff £2.99 £2.99 11.90ppm 11.90pm 1.40ppm 1.40ppm

None Not offered 9.90ppm 9.90ppm 1.19ppm 1.19ppm

£2.00 £2.00 7.10ppm 7.2ppm 1.00ppm 0.80ppm

All prices subject to VAT, prices may vary yadda yadda yadda. In otherwords, these are the prices I found when I looked – the prices you might be charged and might find may be different.

Correction: 14 Feb 2011 13:41: Previously AAISP’s prices were shown including VAT. This has now been fixed.


  1. Thank you. A great summary, I started much the same spreadsheet the other day and glad to say you have found some that I didn’t know about 🙂

    Having just started a business I invested in a home router that is also a VPN end point (handy for remote working) and VoIP client for any normal home phone you plug in. It’s by far been the best thing I have bought so far for my business.

    My general findings were that it didn’t really matter which VoIP service you used as long as you didn’t use your normal home phone or mobile! You can fight over 1ppm or 1.4ppm but compared to 20ppm either is fine :-p

    Good to see that you’re staying with VOIP. as Peter Kay would say “It’s the future/”

    Tried to register for a couple of these I came across the following issues (that I thought others might be interested in):

    i. Voipfone’s terms and conditions have the threat of a 450 GBP fine for misuse hidden in their contract

    ii. aql have a lag on issuing you a number, which they only inform you of after you have paid. They will only issue numbers during office hours. They also require your mobile number.
