Just £10 per month


Business phone lines or analogue telephone lines are now primarily used as a bearer line with xDSL broadband services. However they can also be implemented as a single Direct Exchange Line (DEL) for use with alarm systems (Redcare), PDQ, modems or fax – or simply as great value standalone phone line.


Spitfire provide business phone lines through BT Wholesale making it straight forward to transfer an existing service to us.  You are then billed a competitive rate with no change of service or down time.  Once the transfer is completed within just 10 days Spitfire would then become your point of contact for both Support and Billing. Easy.


Choose the fault resolution level which best suits your requirement, right up to a 24/7 service with a 6 hour fix for business critical lines.


To switch your existing BT business phone lines to Spitfire, or to discuss installing new analogue phone lines, please just give us a call on 020 7501 3333 or 0800 319 6363.

Business phone lines in more detail


Business phone lines or analogue telephone lines are a PSTN service rather than ISDN (Public Switched Telephone Network), and are still widely used for a variety of purposes such as alarm lines, lift lines, ADSL bearer lines, PDQ machines, or just as a simple phone line.


There are a number of support options available from Service Level 1 (SL1) through to Service Level (4) – the difference being in the Service Level Agreement fault-repair times.


For a normal business service, Spitfire always recommends Service Level 2 as a minimum.  From just £1.50 per month this provides target fault clearance by the end of the next working day.  


For business critical phone lines we recommend Service Level 3 as a minimum – providing 24/7 cover and a target fault clearance of end of next half working day.

Cost comparison


  • Business phone line rental with Spitfire is 37% cheaper than BT on a 12 month contract. BT business phone line rental is £15.90 per month vs Spitfire £10 per month.
  • Spitfire’s new line installation price is also 18% cheaper than BT – costing £99 as opposed to BT’s fee of £120.
  • Restart a line on site for just £10 with Spitfire – that’s over 70% less that BT.
  • Already have a BT phone line? Then switching to Spitfire is easy and just a straight forward admin change – the line itself doesn’t change, you’re simply transferring your billing and account management to us.
