Start with your project
Choose a focused room renovation or a coordinated refurbishment. Each service page explains the scope in more detail and gives you a direct route to discuss the work.
01 Terraces and whole homes
Connect the kitchen, bathrooms and living rooms in one considered refurbishment. Start with the condition and layout of the house, then coordinate retained stairs, fireplaces and joinery with structural work, heating, electrics and new finishes.
02 Converted flats and apartments
Make a converted flat or apartment work better without overlooking the wider building. Coordinate storage and room layouts with lease permissions, shared drainage, floor construction, ventilation and the route through common areas.
03 A focused room renovation
Discuss a standalone bathroom renovation, en-suite or wet room as its own project. Fit the layout to the existing structure and service routes, and bring waterproofing, extraction, lighting, tile setting and fittings into one specification.
Space, light and considered storage
Considering more space or a better use of existing rooms in Angel and Islington? Compare loft conversion, house extension and bespoke joinery options with the building, ownership and local controls before fixing the brief.
Explore a loft bedroom or workspace in Angel and Islington, with the room layout and stair considered alongside the roof form and the ownership of the building.
The Angel CA18 guidelines include a property-specific traditional roof-extension schedule. Check the correct conservation area and the actual property before choosing a mansard or dormer.
Where accommodation is above another flat or commercial space, establish the roof demise, structure and lease requirements before developing the design.
Plan a kitchen, dining or living-space extension in Angel and Islington, connecting the addition with the existing rear layout and the outdoor space available.
For CA18 properties, assess the addition’s scale and relationship to the existing building and windows. The guideline is not a permission template for wider Islington.
Show the intended footprint, adjoining openings and relevant structural or excavation work so private rights and Party Wall procedures can be assessed.
Make an Angel or Islington home more practical with fitted wardrobes, alcove cupboards, bookshelves and compact study storage, designed around the rooms and openings you already have.
Identify original windows, doors and any shopfront details before replacement work is designed; apply the guideline for the correct conservation area.
Coordinate interior storage with existing fabric and shared access. Changes to listed interiors or complete fire doorsets need a separate assessment from decorative finishes.
Tell us how you want to use the space, what needs to stay and which drawings or permissions you already have. A measured brief can connect the roof or extension layout with stairs, storage, lighting and joinery before specifications are priced.

Local knowledge with a purpose
An Upper Street address, a terrace by the New River Walk and a flat above a shop can need very different renovation briefs. Understand both the building and its surroundings before choosing a layout or specification.
The Angel and Upper Street (North) conservation guidelines describe a mix of older buildings, narrow plots, commercial frontages and residential uses. A home behind or above a shop may share an entrance or services; establish the lawful use, access rights and existing arrangements rather than treating every N1 property as a detached house.
The Angel conservation design guidelines · Upper Street North conservation design guidelines · Islington permitted development and Article 4 directions
Duncan Terrace/Colebrooke Row has its own conservation area and design guidelines. The terraces and landscape around the New River Walk give a different context from the shopping streets. Record surviving windows, railings, stairs, plasterwork and fireplaces, and check individual listing before proposing their alteration.
Duncan Terrace and Colebrooke Row design guidelines · Historic England: listed-building consent
Chapel Market/Penton Street is another separately mapped conservation area. Buildings near the canal or in other parts of Islington need their own designation and planning-history checks. Existing conversion, extension or basement work does not by itself show what can be altered now.
Chapel Market/Penton Street conservation design guidelines (CA33) · Islington conservation-area register and map · Current Islington Local Plan and policies map
The first local check
Confirm the local authority, search the property on the council map, and open the relevant conservation guideline, listing entry, Article 4 direction and planning history. Angel and Islington is the service area; an N1 postcode does not establish one consent route for every home.

Separate checks, one coordinated brief
One approval does not settle every requirement. Identify the applicable routes before ordering work, and record who will prepare submissions, arrange inspections and provide the relevant completion information.
What part of the proposal is development?
Ordinary internal alterations generally do not need planning permission. Extensions, changes of use, new external openings and other development need a separate assessment. Householder permitted development rights have limits and conditions and do not extend to flats; check local directions and previous conditions against the actual proposal.
When planning permission is required · Householder permitted development technical guidance · Islington permitted development and Article 4 directions
Will the work affect special interest?
Check the individual listing. Listed-building consent is required for work affecting a listed building’s special architectural or historic interest, including relevant internal changes. Conservation-area designation is a different control. Avoid assuming that a new bathroom, replacement window or removal of internal detail is exempt or always needs the same consent.
Historic England: listed-building consent · Islington conservation-area register and map
What must be checked and recorded?
Structural alterations, drainage, ventilation, electrical work and other parts of a refurbishment can engage Building Regulations. Establish the approval, competent-person and inspection routes applicable to the scope, and agree who supplies the completion records. A planning decision does not settle these separate requirements.
When Building Regulations approval is needed
Which private rights and notices apply?
Read the lease and obtain any required written landlord consent for flat alterations. Confirm rights over shared services and common areas. Separately check whether work to shared walls, boundaries or nearby excavation engages the Party Wall Act. A Licence to Alter or Party Wall award is not automatically required for every bathroom refit.
LEASE: alterations and home improvements · Party-wall work requiring notice
Local facts that affect the brief
The council lists The Angel (CA18), Upper Street (North) (CA19), Duncan Terrace/Colebrooke Row (CA3) and Chapel Market/Penton Street (CA33) as distinct conservation areas. Check the property boundary and the applicable design guideline; a nearby street name does not establish that the whole home or proposal falls within one area.

Islington’s conservation-area directions can remove particular permitted development rights, including specified minor external alterations. The council also has separate Class MA directions affecting commercial-to-residential changes of use, including a Camden Passage direction. These are different controls: use the map and operative document to identify the property and the development right withdrawn.
Islington permitted development and Article 4 directions · Camden Passage Class MA Article 4 direction and schedule
The adopted Local Plan brings together Strategic and Development Management Policies, Site Allocations and the Bunhill and Clerkenwell Area Action Plan. The council identifies the previous plan documents as an archive for reference. Use the current policies and map for the address, alongside relevant conservation guidance and the complete proposal.
Current Islington Local Plan and policies map
The council adopted its Climate Action SPD on 25 September 2025, replacing the earlier Environmental Design SPD. Read this current guidance and the council’s Retrofit Handbook when considering energy improvements, alongside the heritage and consent checks for the individual home.
Climate Action SPD adoption statement · Islington Retrofit Handbook
Islington says planning permission is usually required to construct a basement. Its Basement Development SPD concerns excavation to create new or additional basement space. A bathroom refit within existing accommodation differs from lowering a floor, extending underground or forming a lightwell. Establish the structural, ground, drainage, tree and neighbour information the particular proposal needs before assuming feasibility.
Islington basement development guidance · Basement Development SPD January 2016 · When Building Regulations approval is needed · Party-wall work requiring notice
Identify the applicable controls before committing to external materials, windows, roof plant or excavation. A conversation or pre-application response is not the same as a granted permission or required private consent.

Local guidance checked . The linked sources help you prepare a brief; requirements depend on the address, building and complete proposal.
From retained details to shared services
Survey existing windows, doors, plasterwork, floorboards and joinery before deciding what to repair or replace. Use the relevant conservation guidelines and listing information to coordinate proposed changes. A matching appearance alone does not settle the consent question.
The Angel conservation design guidelines · Duncan Terrace and Colebrooke Row design guidelines · Historic England: listed-building consent
Set out the waste route, water supply, waterproofing and extraction before choosing tiles and fittings. Plan service access and avoid concealing unresolved leaks. Moving a bathroom in a flat needs a check of shared connections and any required landlord permission.
When Building Regulations approval is needed · LEASE: alterations and home improvements
Check the existing floor build-up before specifying stone, tiles or timber in a flat. Coordinate acoustic requirements, lease conditions and any structural assessment with the proposed finish. Approved Document E applies to relevant building work; it does not establish one floor specification for every existing apartment.
GOV.UK: Approved Document E, resistance to sound · When Building Regulations approval is needed · LEASE: alterations and home improvements
Identify protected trees and conservation-area tree controls before pruning, excavation or material storage. Notice and consent rules have exceptions and depend on the tree and proposal. Plan root protection and permeable surfaces with the drainage strategy; front-garden paving has its own permitted development conditions.
Tree preservation orders and conservation-area trees · GOV.UK: householder guidance, front-garden surfaces (Class F)
Check existing drainage, ground levels and moisture before fitting out a lower-ground room. For excavation, use the council’s basement guidance to identify site-specific ground, flood, tree and structural evidence. A dry-looking cellar or neighbouring basement does not prove that a new excavation is suitable.
Islington basement development guidance · Basement Development SPD January 2016 · Check long-term flood risk in England
Consider heating, insulation, ventilation and moisture as a whole-building package. In a period home, retain the details that matter and assess how proposed changes affect existing fabric. Check roof plant, external grilles and window changes against local planning controls instead of treating them as purely internal upgrades.
Historic England: a whole-building approach · When Building Regulations approval is needed · Islington permitted development and Article 4 directions
A practical plan for the street and building
Plan the actual delivery route and lawful unloading, skips and scaffolding. Islington directs red-route obstruction applications to TfL, naming Upper Street and City Road as examples; check the authority for the exact frontage. Council parking-bay suspensions and highway licences are separate arrangements. Keep entrances and escape routes usable, and establish rights before using a pavement, market space or canal path.

Islington’s published building-site noise guidance sets normal working hours of 8am–6pm Monday to Friday and 8am–1pm Saturday, with prior approval needed outside these hours. Check any tighter site or building conditions. Agree protection, service isolation and neighbour communication, and temporary facilities if the home remains occupied.

A clear scope before a price
Build the quotation around the rooms, retained fabric and outside work that your property actually needs. Resolve the important unknowns before comparing prices.
Separate known repairs from questions that need opening-up or specialist assessment.
Describe the house, flat or bathroom scope room by room so quotations address the same work.
Identify the applicable professional input, outside work and practical site costs.
Make responsibilities and unresolved decisions visible before agreeing the contract.
Ask for quantities, professional fees, permissions, site facilities, VAT and unknown conditions to be explained. An N1 address does not establish a fixed percentage premium or programme. Agree the sequence after necessary investigations and approvals; a standalone bathroom requires its own room-specific quotation.
From an idea to a workable scope
Send the full address, house or flat type, rooms to change and features to retain. Include photographs of the existing layout, stair or entrance access and any known service or moisture problems.
Share available drawings, the lease, managing-agent requirements, listing information and previous planning or building-control decisions. Note shared drainage, restricted delivery access or garden trees where relevant.
Separate repairs, layout changes, heating and electrical upgrades, bathrooms and finishes. Agree what needs investigation before fixing quantities, specifications and the quotation.
Identify who handles each required approval and inspection. Plan ordering, protection, neighbour contact, occupation and service isolation before construction, then agree the completion information to be handed over.

Yes. We can discuss a family bathroom, en-suite or wet room as a focused project, as well as bathrooms within a larger refurbishment. Send the room dimensions and existing layout, and identify the water, drainage and extract routes. Tell us if it is your only bathroom so temporary arrangements can be discussed.
No. The Angel, Upper Street (North), Duncan Terrace/Colebrooke Row and Chapel Market/Penton Street are separate mapped conservation areas. Check the complete address and applicable guideline on the council map. A neighbourhood name or an N1 postcode does not establish the designation.
Islington conservation-area register and map
No. Read the direction for the property and the specific development right it withdraws. Conservation-area directions and Class MA commercial-to-residential directions control different work. Check any previous planning conditions too; do not infer a rule for an internal bathroom refit from a nearby change-of-use direction.
Islington permitted development and Article 4 directions
Ordinary internal alterations generally do not need planning permission. Relevant work affecting a listed building’s special interest may need listed-building consent. Building Regulations, lease permissions and qualifying Party Wall notices are separate checks. External work and changes of use need their own assessment.

Householder permitted development rights do not extend to flats. Assess external alterations, extensions and other development against the applicable planning route. For internal work, also check the lease, shared structure and services, and the relevant Building Regulations requirements.

Islington adopted its current Local Plan on 28 September 2023. Start with its current policies and map, then the relevant conservation guidelines, listing and operative directions. The council keeps previous Local Plan documents in an archive for reference; they should not be mistaken for the current adopted plan.

No. Refitting an existing lower-ground room differs from excavation, deepening, enlargement or a new lightwell. Islington’s published Basement Development SPD concerns new or additional basement space. Establish the planning route and necessary site-specific investigations before assuming that excavation or a new bathroom layout is feasible.
Islington basement development guidance · Basement Development SPD January 2016 · When Building Regulations approval is needed
Identify shared stacks, waste falls, water pressure and the extract route. Check floor construction, acoustics and service access, and read the lease for any required written landlord permission. Coordinate service isolation and protection of common areas with the relevant building manager.

The council’s published building-site noise guidance gives normal hours of 8am–6pm Monday to Friday and 8am–1pm Saturday, with prior approval needed outside those hours. Confirm any tighter building or site conditions before programming work, and plan deliveries and neighbour communication separately.
