Broadband speeds in Epping Forest
Share of premises by the fastest download speed available, averaged across every Epping Forest postcode.
Two of the nineteen outward codes carry almost all the recorded fibre. E4 reaches 87.9 per cent of its postcodes and RM4 sits a whisker behind on 87.8, yet the district-wide full fibre figure is just 7.1 per cent. That mismatch means fibre is dense where it exists and missing almost everywhere else, with CM15, CM16 and CM17 all recording zero.
The rest of the picture is comfortable. Superfast covers 96.2 per cent of postcodes, essentially level with the national norm. Gigabit-capable lines reach 84.7 per cent, and where fibre is absent that availability points to cable network coverage. The slow end has nearly vanished too: 0.9 per cent of the district's 3,434 postcodes sit below 10 Mbps. Only the fibre map looks lopsided. Everything else reads like a well-served district whose averages can broadly be trusted.

Epping Forest at a glance
A household choosing between addresses here faces two different markets. In E4 or RM4, full fibre is a realistic expectation and gigabit speeds a straightforward order. In the CM codes, cable or a superfast line is the practical option, and 30 Mbps or better remains available at the overwhelming majority of postcodes. With under 1 per cent of postcodes below 10 Mbps, genuinely poor connections are rare whichever side of the divide an address lands on.

Epping Forest broadband FAQs
Which parts of Epping Forest district have full fibre?
E4 and RM4, where fibre to the premises reaches 87.9 and 87.8 per cent of postcodes respectively. No other outward code in the extract records any.
Why is the district's overall full fibre figure only 7.1 per cent?
Because the build is concentrated in two of nineteen outward codes. High coverage in E4 and RM4 averages out against zeros across the CM codes.
Is broadband in CM16 slower than the rest of Epping Forest?
CM16 shows zero full fibre in the current data, but that says nothing about cable availability at a given address. Checking the specific postcode is the only reliable answer.
How common are very slow connections in Epping Forest?
Rare. Just 0.9 per cent of the district's 3,434 postcodes fall below 10 Mbps.
Does Epping Forest meet the UK average for superfast coverage?
Close to it. Superfast reaches 96.2 per cent of postcodes here, against a national figure of roughly 97 per cent of premises.
