Swish Fibre Broadband Review 2026

Swish Fibre is a Home Counties Full Fibre altnet operating its own XGS-PON FTTP network across Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey, Sussex, Oxfordshire, Hampshire, Northamptonshire, and parts of Yorkshire. As of April 2026, it covers approximately 250,000 premises and offers Swish 400 (400Mbps) at £35/month and Swish 900 (900Mbps) at £55/month on 18-month contracts, with an eero Pro 6E mesh router included. Latency of approximately 2ms has been recorded in independent tests.

Packages and Pricing

Swish Fibre offers two residential tiers on its own network: Swish 400 at £35/month and Swish 900 at £55/month, both on 18-month contracts. Speeds are symmetrical — upload and download are equal. The eero Pro 6E mesh router (worth approximately £250 retail) is included free with both plans. A six-month half-price promotion was running on 24-month contracts up to March 2026; check for current promotions before signing up. Swish also resells on CityFibre in some areas, offering C-150 (150Mbps) at £32/month and C-500 (500Mbps) at £34–£35/month on 24-month contracts. In areas served by both its own network and CityFibre, Swish's own XGS-PON product tends to offer lower latency and higher future upgrade potential. Compared with Gigaclear and BT in its coverage area, Swish's 400Mbps symmetric at £35/month is competitive for the specification. There are no rolling monthly contract options on the main FTTP range; 18 months is the minimum term. No TV or phone bundles are offered.

Performance: Speeds, Reliability, and Latency

Swish Fibre's XGS-PON network has been independently tested to exceptional speeds: TotalTele recorded over 9,000Mbps download in a residential speed test, confirming the network infrastructure's multi-gigabit future potential. In everyday use, Swish 400 customers consistently achieve 380–420Mbps in both directions on wired connections. Swish 900 customers regularly see 870–950Mbps symmetrical. Latency is one of Swish's standout metrics: ISPreview.co.uk tests have recorded approximately 2ms on the own-network FTTP product — significantly below the 7–15ms typical of Openreach-based providers. This makes Swish an excellent choice for online gaming and real-time applications. The included eero Pro 6E router provides Wi-Fi 6E coverage and handles multi-device households well, including larger properties that would require extenders on a standard router.

Customer Service and Satisfaction

Swish Fibre is not large enough to be tracked in Ofcom's major ISP satisfaction surveys. Independent reviews on ISPreview.co.uk are generally positive, with customers citing good installation experiences and responsive customer service. As a relatively young network in active expansion, Swish occasionally faces installation delays in newly deploying areas — a common challenge for growing altnets. There is no dedicated Ofcom complaint data available, but Trustpilot and independent comparison sites suggest a satisfaction level broadly in line with the UK altnet average. Customer service is available by phone and online chat. Compared with Sky and BT, which have larger support teams, Swish's customer service team is smaller but typically more responsive for technical issues on its own network. No mid-contract price rises are applied during the contract term.

Verdict: Who Is Swish Fibre Best For?

Swish Fibre is an excellent choice for households in its Home Counties and Yorkshire coverage area that want high-performance symmetrical broadband with future-proof infrastructure. The 2ms latency, Wi-Fi 6E eero router, and no-mid-contract-price-rise policy are all compelling advantages over major ISPs at the same price point. The Swish 400 plan at £35/month offers symmetric performance that BT and Sky's Openreach-based products simply cannot match on upload speed. It is best suited to tech-forward households, remote workers, gamers, and families who stream or upload large files frequently. If price is the absolute priority and you only need download speeds, Gigaclear's promotional entry pricing from £16/month undercuts Swish. But for the combination of symmetric speed, router quality, and low latency, Swish Fibre is one of the better altnet choices in its coverage area.
