Government Cuts Red Tape for Fibre Broadband Installs in England
WHAT THE NEW FIBRE CABLING RULES MEAN FROM SEPTEMBER 2026
Fibre installs should get a little less painful
The government has published new directions that should make some fibre broadband installation work easier in existing buildings in England.
From 1 September 2026, certain small fibre cabling jobs will no longer need to go through the same building-control procedures as before. The key point is the 25mm rule: the dispensation covers holes of 25mm or less through internal or external walls for fibre optic cabling.
That sounds technical, but it matters. A lot of full fibre delays happen at the final stage: getting the cable from the network into the building and then to the customer. Flats, shared buildings and older premises can be especially awkward.
This does not give installers a blank cheque. Firestopping, weatherproofing, soundproofing, competent work and proper approval still matter. The change is about removing avoidable paperwork for small, defined cabling work.

What changes?
The government is using powers under the Building Act 1984 to relax some building-control procedural requirements for telecoms work. For broadband, the practical change is aimed at small fibre cabling holes in existing buildings.
In simple terms, if an installer only needs to drill a hole of 25mm or less through an internal or external wall for fibre cabling, some of the usual procedural steps should no longer be needed once the rules take effect.
That should help where a broadband provider can reach a building, but the last bit of cabling is being slowed down by processes that are out of proportion to the work.
Worth noting: the rule is narrow. It is about small fibre cabling holes through walls. It is not a general pass for bigger works, floor penetrations, ceiling penetrations or poor installation standards.
Why this matters
Full fibre rollout is not just about digging streets or building networks. The final connection into the property can be the part that holds everything up.
This is especially true in blocks of flats, converted buildings and shared premises. A network may be nearby, but customers can still end up waiting if access, cabling routes or building processes slow the job down.
Removing some of that friction should make life easier for ISPs, landlords and installers. More importantly, it could help customers get connected sooner where a small wall hole is the main practical obstacle.
What customers should know
- It does not start until 1 September 2026. Before then, the existing process still applies.
- It applies to England. Scotland, Wales and Northern Ireland can have different rules.
- It will not solve every delay. Wayleaves, landlord permission, provider availability and appointment slots can still hold things up.
- Safety checks still matter. Good installers should still seal holes properly and protect against fire, water and sound issues.
- Flats may benefit most. The change is most useful where fibre has to be routed through shared or existing building fabric.
Final view
This is a sensible change for full fibre rollout in England. Small cabling jobs should not be buried under unnecessary process, especially when better broadband depends on getting fibre into real buildings, not just past them.
The important caveat is safety. The best outcome is faster installation with proper firestopping, weatherproofing, product standards and records. If providers use the dispensation carefully, it should help customers. If they use it carelessly, it will create avoidable problems later.
Overall: useful, practical and pro-rollout — but not a reason to cut corners.
FAQs
WHAT HAS THE GOVERNMENT CHANGED?
The government has issued directions that remove some building-control procedural steps for defined fibre optic cabling work in existing buildings in England.
WHEN DOES IT START?
The fibre cabling dispensations start on 1 September 2026 and are proposed to last for three years.
WHAT SIZE HOLES ARE COVERED?
Holes of 25mm or less through internal or external walls for fibre optic cabling are covered. Holes through floors or ceilings are not covered.
ARE SAFETY RULES BEING REMOVED?
No. Firestopping, weatherproofing, soundproofing, competent work and Building Regulations compliance still matter.
WILL THIS SPEED UP FULL FIBRE INSTALLS?
It should help in some existing buildings, especially flats and shared premises, but it will not remove every barrier such as wayleaves, landlord access or provider coverage.
