- Best for (20 words max)
- Resellers and public sector networks wanting wholesale full fibre underlay, not a direct MPLS service.
- Review date (YYYY-MM-DD)
- 2026-10-06
- Strength 1 (25 words max)
- Operates a full fibre XGS-PON network with an MPLS core for its wholesale PWAN and IP VPN products.
- Strength 2 (25 words max)
- Lists access from 100 Mbit/s to 10 Gbit/s, and PoPs in London, Slough, Manchester and Edinburgh.
- Strength 3 (25 words max)
- Publishes a 9 week install lead time.
- Weakness 1 (25 words max)
- It sells through partners only, so a UK business cannot contract directly.
- Weakness 2 (25 words max)
- No SD-WAN, VPLS or direct MPLS offer was found, and its NHS and council cases use dark fibre or access fibre.
- Weakness 3 (25 words max)
- The PoP cities come from PeeringDB, not a CityFibre map.
- Buyer size fit (comma separated: Large global enterprise, Mid-market, Small business)
- Mid-market
- Verdict (40 words max; must include one figure from the fact sheets and the review month)
- Netify recommends CityFibre as an underlay for partners needing full fibre access from 100 Mbit/s to 10 Gbit/s, not as a direct MPLS supplier. Ask your reseller about its 9 week install lead time. Reviewed October 2026.

- Notes
- Legal name and number are a Companies House name match only. Contracting entity, parent, type, URLs and Ofcom status not yet reviewed. Check whether CityFibre contracts MPLS or IP VPN with UK businesses or is wholesale only. This may be an exclusion. Re-check 2026-10-02 (page-reader wording, confirm on the page): the PSC is CityFibre Networks Limited; ultimate parent is Connect Infrastructure Topco Limited (Antin and West Street Infrastructure Partners). The PWAN datasheet (version Dec 2021) describes IP VPN on an MPLS core with a managed Cisco router and dual resiliency, so it may be dated. Ethernet datasheets say MEF-aligned only, so MEF 3.0 is Not found. The 100% SLA and 5 business hour return to service come from a 2021 leased line page that could not be re-fetched and are left out. 4.5m premises is the business FTTP footprint (January 2026), not leased line coverage. Install lead time 9 weeks is 45 business days for Ethernet 10000 Pro (datasheet). Cells filled on 2026-10-02 from the outside research pass are Partial unless the re-check confirmed them. Not found means the pass searched and saw nothing, not that it does not exist. Verify each against its source row, then set Decision.
