EC4Y · Fleet Street & the Temple
EC4Y is Fleet Street, Whitefriars, Carmelite Street and the Temple — the old newspaper quarter, now offices, wrapped around the Inns of Court. The Temple is one of the few corners of the City where people genuinely live, alongside a handful of upper-floor conversions off Fleet Street. Nearly everything sits within a conservation area and a large share of it is listed, so listed building consent — covering internal alterations as well as elevations — is the usual route, and unauthorised work is a criminal offence. Permitted development does almost nothing.

Real · planning.data.gov.ukCity of London has 28 designated conservation areas and 0 Article 4 areas. A district is too coarse to say which apply to your house — postcode districts span many streets and EC4Y crosses 3 boroughs.

Is EC4Y in a conservation area?
Partly — and which part matters. A postcode district is never uniformly designated: EC4Y contains 27 conservation areas within 1km of its centre, and whether your own property sits inside one decides whether permitted development survives. The centre point of EC4Y itself falls inside Temples.

Does an Article 4 direction apply in EC4Y?
Yes — EC4Y has 22 Article 4 directions mapped within 1km of its centre. An Article 4 direction withdraws specific permitted-development rights on the streets it covers, which is the most common reason a project that looks like permitted development turns out to need a full application. The centre point of EC4Y does not fall inside one, but coverage is street-level — verify your own address.

Do you need planning permission in EC4Y?
Three routes exist, and which one you are on is decided by your address, not your postcode district:
| Permitted development — no application. The work stays inside the GPDO limits and no designation removes them. A Lawful Development Certificate is cheap proof for a future buyer. | No permission |
| Prior approval — the larger single-storey rear extension route, with neighbour consultation. Not available on designated land. | 42 days |
| Full householder application — required once a designation removes your permitted-development right, or the scheme exceeds the limits. | 8 weeks |
EC4Y contains mapped conservation-area or Article 4 geometry, so a meaningful share of its streets will have lost some permitted-development rights — which pushes those properties onto the full-application route. Whether yours is one of them is an address-level question, not a district-level one.
What does planning permission cost in EC4Y?
| Householder planning application | £548 (from 1 April 2026) |
| Lawful Development Certificate — proposed works | £274 (half the application fee) |
| Lawful Development Certificate — existing works | £548 (the full application fee) |
| Listed building consent | No fee |
| Resubmission after a refusal | Free once, within 12 months of the decision |
National statutory figures for England — councils do not set them, so they are the same in every borough. Planning fees re-index every 1 April; confirm the current amount on the Planning Portal fee calculator before you apply. These are the council's fees only — drawings, surveys and any specialist reports are separate.
How long does it take?
| Householder application — statutory target | 8 weeks |
| Householder application — in practice | 8–12 weeks |
| Prior approval (larger home extension) | 42 days |
| Lawful Development Certificate | 8 weeks |
| Householder appeal — deadline to lodge | 12 weeks from the decision date |
| Householder appeal — typical decision | Around 18 weeks |
What if it's refused?
A refusal is a decision notice with reasons attached, and those reasons are a roadmap. Most homeowners in City of London — as anywhere in England — are better served by amending the scheme and using the free resubmission than by appealing: you get one further application on the same site within 12 months without paying again.
| Who can appeal | The applicant only — not neighbours |
| Fee to appeal | None — you bear your own costs |
| Procedure | Written representations for most householder appeals |
| Success rate | Roughly a third — about 36% of householder appeals allowed in 2025/26 |
Appeals go to the Planning Inspectorate, an independent national body. How to read a refusal and choose your route →
