Street naming and numbering charges on a new scheme
A finished house without an official address has no postcode, no utility accounts and no realistic mortgage offer. Here is how allocation works, what it costs and when to apply.
Street naming and numbering is the small administrative step that stops a finished house from being sold. The council allocates the address, not the developer and not the builder, and the street naming and numbering cost is a locally set charge rather than a national fee, usually a base amount plus a sum for each plot. Apply early. A new dwelling without an official address has no postcode, and without a postcode it has no utility connections, no council tax band, no broadband order and, in practice, no mortgage offer for the buyer.
Why the council allocates addresses
The function is statutory but old. Local authorities rely on one of several nineteenth and early twentieth century regimes, commonly the Towns Improvement Clauses Act 1847, the Public Health Acts Amendment Act 1907 or the Public Health Act 1925, depending on which the authority has adopted. That is why procedures differ between neighbouring councils in a way that looks arbitrary.
The council maintains the local land and property gazetteer, which feeds the national address database used by the emergency services, utilities and government. Once the council has allocated an address it notifies the postal operator, which assigns the postcode and adds the property to the postal address file.
The practical consequence is that you cannot obtain a postcode directly. A developer who writes to the postal operator before the council has acted gets nowhere, and an address invented for marketing purposes has no standing at all.
The application and the local charge
Applications are made to the council's street naming and numbering team, usually online, after planning permission is granted and with the approved layout attached. Expect to supply the permission reference, a site plan showing plot numbers, floor plans for flats, the developer's contact details and any proposed street names.
Charges are set locally rather than nationally, under the general power for authorities to charge for discretionary services, and they are published. The usual structure is a base fee for the scheme, an amount per dwelling or unit, a separate fee for naming a new street, and further charges for later changes, renaming or renumbering. Street name plates are often an additional cost, supplied and erected to the authority's specification.
Do not budget from a figure quoted on a forum. Download the current schedule from the authority's own website, because these charges are reviewed annually and vary widely between councils. This belongs in the same part of the cost plan as the other post-permission charges discussed in our note on budgeting for CIL and the exemption paperwork.
Naming a new street
Where the scheme creates a new street, you may usually propose names, and the council decides.
Most authorities apply a published set of rules, which run along these lines.
- No duplication of, or close similarity to, an existing street name within the same postal town, because similar names cause emergency service errors.
- A preference for names with local historical, geographical or ecological relevance, evidenced rather than asserted.
- No names of living people, and caution with recently deceased people.
- Names that cannot be misread, misheard or spelled several ways, and no apostrophes or punctuation.
- Suffixes used accurately: a cul-de-sac is a close, a through route is a road or street, and a short terrace is not a way.
- Consultation with ward or parish councillors, the emergency services and sometimes a local history group.
Submit three or four options in order of preference with a short justification for each. A single proposal with no fallback adds a round of correspondence, and councils reject more names than developers expect.
Timing against completion and utility connections
This is the part that costs money when it goes wrong, because several processes depend on the address rather than on the building.
| Depends on an official address | Effect if it is missing |
|---|---|
| Electricity, gas and water connections | Supplier cannot create an account or a meter point reference |
| Broadband and telephone orders | No order can be placed, so a buyer moves into a house with no connection |
| Council tax banding by the valuation office | No band, which delays the buyer's liability and sometimes the completion |
| Land Registry first registration of the plot | Registration proceeds on a plan, but the address description matters on sale |
| Warranty and insurance | Policies issued against a plot reference have to be amended |
| Energy performance certificate lodgement | The certificate needs the address that will be used |
Councils publish target timescales for allocation, and the postal operator then takes its own time to add the address. Ask for the published target, add the postal stage, and work backwards from your intended completion date. On a single self-build, applying when the walls go up rather than when the roof goes on is the right instinct.
Where the scheme includes new roads, the naming application interacts with the adoption process and the street works programme, which is covered in our note on section 278 and section 38 highway costs.
When the wrong address delays a sale
Three failure modes recur.
The first is marketing a plot under a name the council later rejects. Sales particulars, the warranty, the mortgage offer and the draft transfer all carry the wrong address, and amending them takes weeks at the point when everyone wants to complete.
The second is numbering that changes late. Where the council renumbers plots to produce a logical sequence along a street, plot 4 may become number 11, and every document that referred to plot 4 needs checking. Keep a plot to address schedule and issue it formally to the solicitors, the warranty provider and the utilities as a single controlled document.
The third is the flat conversion where the council requires a different format from the one the developer used. "Flat 3, 14 High Street" and "14C High Street" are not interchangeable, and the postal operator's records follow the council's decision rather than your brochure.
None of these are planning matters, which is exactly why they get missed. Nobody raises them at a planning committee.
Renumbering an existing building after conversion
Converting a house into flats, or a commercial building into dwellings, needs new addresses for each unit and often a revised position for the original building.
The council will normally require a numbering scheme submitted with floor plans showing each unit and its entrance. It then allocates flat numbers or letters, notifies the postal operator, and updates the gazetteer. Where the building has a name as well as a number, adding or changing that name usually needs the council's agreement too, and some authorities charge for it separately.
Tell the existing occupiers of neighbouring properties if their numbering changes as a consequence, which happens when an infill plot is squeezed into an existing run. Councils will consult them, but a letter from the developer explaining the change prevents a good deal of local irritation.
Adding the step to a completion checklist
Treat it as a line item with an owner and a date, not a job someone remembers at the end.
- At permission stage, note the authority's current charges and target timescale, and add both to the cost plan and the programme.
- Submit the application with the approved layout as soon as the plot layout is settled, and before marketing names are used anywhere.
- Propose several street names with justifications, and do not print anything until one is confirmed.
- Issue a controlled plot to address schedule to the solicitors, warranty provider, utilities and building control.
- Confirm the postal operator has the address before your first intended completion.
- Order street name plates to the authority's specification if that obligation falls to you.
- Keep the allocation letter with the title documents, because a buyer's solicitor may ask for it.
You can see what the documents in a planning submission cost on the pricing page, and work through which of them a scheme needs on the report index. The address application is separate from all of it, and nobody else will chase it for you.
This is general guidance, not legal advice. Street naming and numbering procedures, powers and charges differ between authorities, so check your council's own published policy and current charges before relying on it.
Frequently asked questions
Who allocates the address for a new house?
The local authority, under one of several older statutes that councils have adopted, which is why procedures differ between neighbouring areas. The council maintains the local gazetteer and notifies the postal operator, which then assigns the postcode. You cannot obtain a postcode directly, and a marketing address has no official standing.
What does street naming and numbering cost?
There is no national fee. Councils set and publish their own charges for the service, usually a base amount for the scheme plus a sum for each dwelling, a separate fee for naming a new street, and further charges for later changes. Street name plates are often extra. Download the current schedule rather than relying on an older figure.
When should I apply?
Once permission is granted and the plot layout is settled, and well before first occupation. Utility connections, broadband orders, council tax banding, warranty documents and energy certificates all depend on the official address. On a single self-build, applying when the walls go up rather than at roof stage is the right instinct.
Can I choose the name of a new street?
You can propose names and the council decides. Expect rules against duplication or close similarity within the postal town, against names of living people, and against spellings that can be misheard, plus a preference for evidenced local relevance. Submit three or four options in order of preference with short justifications.
What happens if plot numbers change to street numbers late?
Every document referring to the plot needs checking, including sales particulars, the warranty, the mortgage offer, the transfer and the utility accounts. Keep a controlled plot to address schedule and issue it formally to the solicitors, warranty provider, utilities and building control as soon as the council confirms the allocation.
How are flats addressed after a conversion?
The council allocates the format, which may be a flat number or a letter suffix, based on floor plans showing each unit and its entrance. Those formats are not interchangeable, and the postal operator follows the council rather than your brochure. Adding or changing a building name usually needs the council's agreement as well.
