Putting a mobile phone mast on a church tower
Three permissions, three bodies, three tests. How Part 16 prior approval, the ecclesiastical exemption and the faculty jurisdiction fit together on a church tower installation.
Three separate permissions can apply to a telecommunications installation in a church tower, and they are granted by three different bodies on three different tests. The council deals with planning, usually through the prior approval route in Part 16 of the General Permitted Development Order. Listed building consent is the second, and for most listed places of worship still in use it is replaced by the denomination's own internal system under the ecclesiastical exemption. For a Church of England building that internal system is the faculty jurisdiction, and the Diocesan Chancellor decides it.
An operator who secures prior approval and then discovers the faculty has not been granted has wasted a year. The order of work matters.
Prior approval for telecommunications apparatus
Part 16 gives electronic communications code operators permitted development rights for a range of apparatus, including antennas on buildings, with a prior approval procedure that lets the council consider siting and appearance.
Prior approval is narrower than planning permission. The council is considering where the apparatus goes and what it looks like, and it cannot refuse on other grounds. National policy is explicit that authorities should determine these applications on planning grounds only, should not question the need for the network, should not seek to prevent competition between operators, and should not apply health safeguards different from the recognised international exposure guidelines.
Part 16 has been amended repeatedly, including changes intended to support network rollout, so take the limits from the current text rather than from an older note. The rights exclude a number of situations, and listed buildings and scheduled monuments are among them, which is precisely the position a church tower is usually in.
Where the right does not apply, the operator makes a full planning application instead, and the council then considers the proposal against the development plan in the ordinary way.
Where the ecclesiastical exemption does and does not apply
The Ecclesiastical Exemption Order 2010 removes the need for listed building consent for works to certain listed places of worship, where the denomination operates its own approved system of control. The Church of England, the Roman Catholic Church, the Methodist Church, the Baptist Union and the United Reformed Church are the bodies covered.
Three limits on the exemption catch people out.
It applies only while the building is in use for worship. A redundant church, or one in alternative use, loses the exemption and needs listed building consent in the usual way.
It covers the listed building, objects or structures fixed to it, and certain structures within the curtilage, so an antenna on the tower is within scope while a new access track across the churchyard may not be.
And it never replaces planning permission. The exemption is about listed building consent only, and the council's planning function is unaffected by it.
Churches of other denominations, and independent chapels, have no exemption at all and need listed building consent from the council for any works affecting the character of a listed building.
Listed building consent for a tower installation
Where the exemption does not apply, listed building consent is needed for works affecting the character of the listed building as a building of special architectural or historic interest. Fixings into historic masonry, cutting cable routes, enlarging an opening, altering louvres and attaching equipment internally all qualify.
Carrying out such works without consent is a criminal offence, and it is one of the few areas of planning law with that consequence. There is no four or ten year immunity for unauthorised works to a listed building.
A Heritage Statement explaining the significance of the tower, the effect of the installation and how harm has been avoided or reduced is the document that carries the decision. For a telecoms installation the significant points are usually the reversibility of the fixings, whether any historic fabric is lost, and the visual effect on the belfry openings.
Historic England publishes advice on telecommunications in historic buildings, and its position broadly favours installations that are reversible, concealed and cause no loss of fabric.
Visual impact and the siting of antennas
The design question is almost always the same: how to put antennas inside a stone tower without changing how the tower reads.
Four approaches are used, in rough order of acceptability.
Antennas mounted inside the belfry behind the existing louvres, where the stone and timber are thin enough to transmit adequately. Replacement of existing timber louvres with glass reinforced plastic replicas matched to the original profile and paint colour, with the antennas behind them. Antennas inside the tower behind a window opening fitted with a radio-transparent panel. And, least often accepted, antennas mounted externally on the parapet or behind a shroud.
The practical constraint is radio performance. Stone attenuates signal, and the thicker the wall the more the operator will want an opening. That tension between concealment and coverage is the technical heart of these applications, and it is resolved by the radio engineer rather than by the planner.
Photographic evidence decides the case. Views from the churchyard gate, from the nearest residential street and from any longer view where the tower is a landmark, with the proposal superimposed, will tell the officer more than any written assessment.
Cabinets, cable routes and ground level equipment
The antennas are rarely the problem. The equipment cabinets are.
A typical installation needs cabinets housing radio equipment, power and a battery backup, and they have to go somewhere accessible for maintenance. Options are inside the tower at ground level, in an adjacent outbuilding, or in an enclosure in the churchyard.
Churchyard siting raises issues that have nothing to do with planning. Burials, consecrated ground, monuments and the possibility of disturbing human remains are faculty matters, and a diocesan chancellor will look hard at any excavation in a churchyard. Where archaeology is likely, the county archaeologist will want a watching brief at minimum.
Cable routes are the other overlooked element. A cable run up the inside of a tower wall, fixed into historic plaster or stone, is works to a listed building whatever the exemption position, and an external run is a visual intrusion that is hard to justify.
Plan the whole installation, cabinets and cables included, before submitting anything. Applications that deal with the antennas and leave the cabinets to be agreed later tend to come apart at the second stage.
The health declaration and what it covers
Every application for telecommunications apparatus is expected to be accompanied by a declaration that the installation will comply with the recognised international guidelines on limiting exposure to electromagnetic fields, issued by the International Commission on Non-Ionizing Radiation Protection.
The declaration is a statement about the installation as designed and commissioned, signed by someone competent to make it, normally a radio frequency engineer acting for the operator. National policy is clear that councils should not set health safeguards different from those guidelines, and that the presence of a compliant declaration means health concerns carry no weight in the decision.
That is a hard message to deliver at a parochial church council meeting, and it is the right one. Objections on health grounds will not affect the planning decision, and a council that refuses on those grounds is likely to lose an appeal with costs.
A Telecommunications Compliance document sets out the declaration and the supporting technical information. Councils normally expect it to be prepared by a suitably qualified radio frequency engineer, and professional review before submission is strongly advised.
Faculty jurisdiction alongside planning
For a Church of England building, a faculty is the internal permission, granted by the Chancellor of the diocese on the advice of the Diocesan Advisory Committee.
The process is slower than planning and the test is different. The committee considers the effect on the building's significance, whether the proposal is necessary, and whether any harm is justified by public benefit, applying the questions the courts have set out for works to listed churches. It also considers matters a council would never touch: the terms of the lease to the operator, the income to the parish, access arrangements for engineers, interference with the bells or the clock mechanism, and the view of the congregation.
Allow for a longer programme. A Diocesan Advisory Committee meets periodically, a faculty petition is publicised locally, and objections are dealt with by the Chancellor in writing or at a hearing.
Assembling the submission
The order that works, for a Church of England tower:
- Radio survey and a feasibility discussion with the diocese before any design work
- Diocesan Advisory Committee informal advice on the concealment approach and the cabinet location
- Heads of terms for the lease, since the Chancellor will want to see them
- Design freeze covering antennas, cabinets and cable routes
- Planning submission, with a Planning Statement, a heritage statement, the compliance declaration, photographs with the proposal superimposed and a maintenance access plan
- Faculty petition, running in parallel where the diocese is content
The honest uncertainty is in how individual chancellors weigh parish income against harm to a listed building. Faculty decisions are published, and they vary more than planning decisions do.

Frequently asked questions
Does the ecclesiastical exemption remove the need for planning permission?
No. The exemption under the Ecclesiastical Exemption Order 2010 removes the need for listed building consent for works to certain listed places of worship still in use for worship, where the denomination runs its own approved control system. Planning permission or prior approval from the council is still required, and the exemption does not touch it.
Can a council refuse a mast on health grounds?
No. National policy is clear that authorities should not set health safeguards different from the recognised international exposure guidelines, and applications are expected to carry a declaration of compliance with them. A refusal on health grounds is likely to be overturned at appeal, potentially with costs awarded against the council.
Which denominations have the ecclesiastical exemption?
The Church of England, the Roman Catholic Church, the Methodist Church, the Baptist Union and the United Reformed Church. Other denominations and independent chapels have no exemption and need listed building consent from the council. The exemption also lapses where the building is no longer in use for worship.
What is a faculty and who grants it?
A faculty is the internal Church of England permission for works to a church, granted by the Chancellor of the diocese on the advice of the Diocesan Advisory Committee. It considers the effect on significance and the justification for harm, and also matters outside planning such as lease terms, parish income and interference with bells or clocks.
What usually causes most difficulty, the antennas or the cabinets?
The cabinets. Antennas can often be concealed behind existing or replica louvres with no loss of fabric. Equipment cabinets need maintenance access and power, and siting them in a churchyard raises consecrated ground, monuments and archaeology issues that the diocesan chancellor examines closely.
