Dishes, aerials and cabling on listed buildings

Satellite dish listed building consent is needed for the fixing, not just for the dish. Drilling four stainless anchors into an 1830s parapet is work affecting the character of a listed building, and that is what section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 controls. Permitted development rights for antennas say nothing about it, because listed building control is a separate regime with its own offence and no time limit for enforcement.

For a landlord with converted flats in a listed terrace, the practical consequence is that every tenant's dish is a potential breach, and the least costly answer is usually to install one system before anyone asks.

Two consents, and one does not cover the other

Keep the two regimes separate in your head.

Planning permission is dealt with by the antenna class in the General Permitted Development Order, which permits a limited number of microwave antennas within size and siting limits, and which restricts installation on designated land where the wall or roof slope faces onto and is visible from a highway. Our note on the antenna class limits covers that side.

Listed building consent is needed separately wherever the work affects the building's special interest. Fixing a bracket into the fabric does. So does running a cable through a wall, cutting a notch in a cill, or lifting lead to pass a cable under a flashing.

The application for listed building consent carries no fee, which removes the usual argument for taking a view and proceeding. A conservation area does not need consent for the dish itself, but the antenna class restrictions apply there and an Article 4 direction may remove them altogether.

Choosing a position that gets consent

Conservation officers approve dishes. What they resist is dishes in the wrong place, and the wrong place is almost always visible from the street.

Positions that get consent, in rough order of success:

1. A pole mount in the rear garden or a rear yard, with a buried cable run and no fixing to the building at all.
2. A rear roof slope below the ridge, in a valley or behind a parapet so the dish does not break the roof line.
3. A rear elevation wall, fixed into mortar joints, below eaves level.
4. An outbuilding or boundary structure, provided it is not itself listed or a curtilage structure of interest, a question our note on walls, railings and gates deals with.

Positions to avoid proposing: chimney stacks, principal elevations, parapets, front roof slopes, and anything visible in the view along a terrace. Line of sight is a real constraint and sometimes forces a visible position, in which case the application has to show the alternatives that were tested and why each failed. A signal survey carries more weight than an assertion.

Specify a dish in a dark matt finish, the smallest that works, and a mesh type where the aesthetics are marginal.

Fixings into historic fabric

This is the detail that decides whether the consent is granted with or without an argument, and it is usually missing from applications.

What a conservation officer wants to see:

• Fixings into mortar joints rather than through the face of brick or stone, so that a future removal leaves repointing rather than a scar.
• Stainless steel fixings, not galvanised, to avoid staining and corrosion.
• Mechanical fixings in preference to resin anchors in soft or friable stone.
• The smallest number of fixings consistent with wind loading, with the loading calculated rather than assumed.
• A note on what happens on removal: joints repointed in a matching lime mortar, no filler.

Draw the bracket. A dimensioned detail at a sensible scale showing the bracket, the fixing positions relative to the brick courses and the mortar specification turns a contested application into a straightforward one.

Avoid fixing to anything structurally marginal. Parapets, cornices, chimney stacks and thin gable walls all move, and a dish bracket is a lever in high wind. Where a stack is involved, the structural question comes first, as our note on chimney stacks sets out.

Cable routes are the part that gets refused

Applicants spend their effort on the dish and lose the application on the cable.

Surface clipped coaxial running diagonally across a principal elevation, stapled over string courses and dropped past window reveals, is the single most common harm in this category. It is also entirely avoidable.

The approach that works:

• Use existing penetrations. Redundant flues, old service holes, air bricks and existing pipe entries all take a cable.
• Route internally wherever possible, in floor voids, roof voids and existing boxing.
• Where an external run cannot be avoided, keep it on a rear or secondary elevation, follow a vertical line in a reveal or against a downpipe, and paint it to match the background.
• Group everything in one containment rather than adding a cable per tenant over the years.
• Never run cables under lead flashings or through lead gutters, which causes the lead to fail and the leak to be blamed on the roofer.

Show the route on an elevation drawing and on a plan. A cable route drawing is rarely submitted and almost always welcomed.

One communal system instead of twenty dishes

For a converted listed building with multiple flats, a single communal reception system is the answer that satisfies everyone. One head-end position, one set of fixings, one cable route into a riser, and a distribution network inside the building.

The arguments for it go beyond appearance:

• One consent rather than a rolling series of individual applications and breaches.
• One set of penetrations through historic fabric.
• A contractual answer when a tenant asks, which is a lease or tenancy clause prohibiting individual installations because provision is already made.
• A system you control at sale or refinance, rather than a facade covered in other people's equipment.

Deal with it at the conversion stage if you can, because the consent for the conversion is the moment when a riser and a head-end position can be designed in. Retrofitting a riser into an occupied building is a much harder project.

Where an operator's apparatus is involved rather than domestic reception equipment, different rules apply, and a Telecommunications Compliance submission may be needed alongside the heritage case.

What to submit

A listed building consent application for antennas and cabling is short, and completeness is what makes it quick:

• A location plan and elevation drawings showing the dish, its diameter, its position and the cable route.
• Photographs from the street, from the nearest public viewpoint and of the proposed fixing position close up.
• The bracket and fixing detail, with the mortar specification.
• The product specification and finish.
• A brief Heritage Statement covering the significance of the elevation, the alternatives tested, and why the chosen position causes least harm.
• Where line of sight forced the position, the signal evidence.

Say plainly what will be removed and made good at the end of the installation's life. Offering that commitment up front usually produces a better condition than the one an officer would otherwise write.

Conditions, removal and enforcement

Expect conditions requiring approval of the fixing detail before installation, a specified finish, a limit on the number of antennas, and removal with making good when the equipment is no longer needed.

The enforcement position is worth being clear about with tenants and managing agents. Unauthorised works to a listed building are a criminal offence, there is no period after which the breach becomes immune, and a listed building enforcement notice can require removal and the making good of the fabric. Removal of a badly fixed dish often costs more than the original installation, because the repair is a masonry job.

Before any installation on a listed building, agree the position, the bracket and the cable route with the conservation officer on site. Half an hour there prevents the whole sequence of problems above. You can browse the report types by category to see which heritage documents the application will need.

This is general guidance, not legal advice. Check the position with your local planning authority's conservation officer or a qualified heritage professional before relying on it.
