The right windows for your home depend more on when and how it was built than on anything else. East London covers ten boroughs and almost every type of London house: Georgian weavers' houses in Spitalfields, Victorian terraces in Hackney, Walthamstow and Forest Gate, the Becontree estate (once the largest council estate in the world), the Arts and Crafts houses of Gidea Park, and the 1930s semis of Bexley and Sidcup.

This guide sets out the main types of home across East London, where each is most common, and the windows and doors that suit it best. It also covers the conservation area and Article 4 rules in each borough, which range from very strict in Lewisham to relatively relaxed in Tower Hamlets.

Aliluxe designs, supplies and installs aluminium, uPVC and timber windows and doors across London. Every recommendation here comes from what we see on surveys.

Georgian and early 19th century houses

East London's oldest houses are mostly near the City and the river, and many are listed.

Where you'll find them

Spitalfields: most houses in Fournier Street were built in 1725–28, and early occupants included silk weavers.
Bow: Tredegar Square was built mainly between 1820 and 1860, with three-storey terraces and a stuccoed north side.
De Beauvoir Town, Hackney: laid out from the 1820s and 1830s, including Benyon Cottages of 1839.
West Greenwich: houses built piecemeal on Crooms Hill from the 17th century onwards, and early 19th-century houses on Royal Hill.
Forest Gate: eight semi-detached houses of about 1839–40 on Romford Road.

What the windows are usually like

Double-hung timber sashes with fine glazing bars, often in nearly flush frames on the earliest houses.
Wide 'weavers' windows' in the top storey of some Spitalfields houses.
Timber window shutters, as in Tredegar Square.

What we recommend

Listed buildings need listed building consent for any window change. Timber is expected, and slim heritage double glazing or secondary glazing is often the practical upgrade.
In conservation areas, timber sashes with correctly proportioned glazing bars are the safe choice. REHAU uPVC sliding sash windows can work where the council accepts them.
Keep shutters working by matching the new frame depth to the old one.

Victorian and Edwardian terraces

Most of inner East London was built between 1850 and 1914, as the railways and workmen's fares brought new streets to Hackney, Walthamstow, Forest Gate and Ilford.

Where you'll find them

Hackney: the number of inhabited houses rose from 9,027 in 1851 to 28,422 in 1891, and the streets around St Mark's in Dalston were built in 1860–70 (the church itself dates from 1864–66).
Brockley, Lewisham: a speculatively developed Victorian suburb, mostly from the second half of the 19th century.
Walthamstow: two-storey yellow-brick terraces with bays were the most common type from 1870 to 1914, alongside the red-brick Warner estates.
Forest Gate and Manor Park: the Woodgrange estate's 1,160 houses were built in 1877–92, and Durham Road in the 1880s.
Ilford: Cameron Corbett's Grange estate began in 1894, and Peter Griggs began the Cranbrook estate in 1897, with long streets of two-storey terraces.
Bow: the terraces around Driffield Road, some with canted bays, were built between 1857 and the 1890s.

What the windows are usually like

Timber sliding sashes, plate-glass sashes with horns on later houses.
Large sash windows in stucco bays, and bays on two storeys on later Woodgrange houses.
Gables, recessed porches and glazed front doors on Warner and Edwardian houses.

What we recommend

Sliding sash windows keep the original look. REHAU uPVC sliding sash windows with run-through horns give the traditional proportions, and Newham's Durham Road guide accepts heritage-style uPVC sashes like these.
In stricter boroughs such as Lewisham, replacements on any visible elevation must match the original material and design, which usually means timber sash.
For bays, use REHAU bay windows or match the sash style across all faces.
At the back, aluminium bi-fold or sliding doors for a kitchen extension.

Garden suburbs and cottage estates

East London has some of the most important planned housing in England, from wartime garden suburbs to the huge London County Council cottage estates.

Where you'll find them

Becontree, Barking and Dagenham: about 25,700 homes by 1938, mostly small two-storey houses in short terraces, called in 1939 'the largest municipal housing estate in the world'.
Downham, Lewisham: an LCC cottage estate of about 7,000 homes, built in 1924–30.
Progress Estate, Eltham: built in 1915 for munitions workers at Woolwich Arsenal, and 'a very fine early example of garden suburb townscape design'.
Gidea Park, Romford: begun in 1910, with an exhibition of 159 houses by 100 architects in 1911.

What the windows are usually like

Six-light timber casements at the Progress Estate, and metal Crittall casements with leaded lights on some houses.
Timber casements with small panes, generally horizontal in proportion, at Gidea Park.
Neo-Georgian cottage windows on the Becontree estate.

What we recommend

On the Progress Estate, timber side-hung casements are preferred, and where uPVC is used, only external glazing bars are acceptable.
At Gidea Park, an Article 4 direction means front and side alterations need permission, and the council is critical of poor uPVC replacements.
On Becontree, REHAU uPVC casement windows with a cottage-style bar pattern suit most houses, and the council's new design code is worth checking first.
Where the originals were steel, heritage steel-look windows give the slim sightlines.

1920s and 1930s semis and bungalows

The outer boroughs, Bexley, Havering, Redbridge and parts of Waltham Forest, filled up with private semis and bungalows between the wars.

Where you'll find them

Bexleyheath and Sidcup: 'rapid sub-urbanisation during the great housing boom', with estates such as Brampton Park in Bexleyheath.
Highams Park, Chingford: The Highams Estate was largely developed in the 1930s by the Warner-associated Law Land Building Department. It consists mainly of semi-detached houses, with prominent bay windows and distinctive Arts and Crafts-influenced architectural details.
Redbridge: a Bungalow Estate of 1920s–30s bungalows in a garden setting, and interwar semis across the borough.
Gidea Park: a second 'Modern Homes' exhibition in 1934, with white rendered flat-roofed houses and steel windows.
Blackheath Park: interwar semis and detached houses on the Cator estate.

What the windows are usually like

Timber casements with leaded lights and coloured glass, plus diamond or oriel side windows, on the Redbridge bungalows.
Two-storey bay windows on most semis.
Steel windows on Moderne houses.

What we recommend

Casement windows suit these houses best. REHAU uPVC casement windows are good value, and Origin OW-80 aluminium gives a slimmer, flush finish.
For the bay, REHAU bay and bow windows keep the original shape. Ask about a structural check, as many 1930s bays have no proper lintel.
On the Redbridge Bungalow Estate, slim-profile uPVC is accepted in some cases where uPVC is already in place.
At the back, French doors or a wide sliding door to the garden.

Estates, flats and modern homes

East London also has a large stock of flats, from the London County Council's first estate to post-war towers and Docklands developments.

Where you'll find them

The Boundary Estate, Shoreditch: built by the LCC in 1894–1900, 'the first to be developed by the authority', with 20 blocks around Arnold Circus.
Span houses: the Blackheath Park Span estate of about 1960, with large plain windows.
Post-war estates: Harold Hill in Havering (7,361 homes, 1948–58), and Heath Park and Marks Gate in Dagenham.
Docklands and Canning Town: 1960s–70s redevelopment and 1980s–90s housing at Beckton.

What the windows are usually like

Timber sashes or steel windows in older blocks.
Large plain timber windows on Span houses.
First-generation uPVC from the 1980s and 1990s, now reaching the end of its life.

What we recommend

Tilt and turn windows for flats and upper floors: REHAU tilt and turn.
Slimline aluminium for a modern look with more glass: Origin OW-70.
Span houses look best with slim frames that copy the large plain panes. Aluminium is often a better match than chunky uPVC.
Flats need the freeholder's consent, and planning permission if the new windows look different.

Conservation areas, Article 4 and listed buildings in East London

Before you choose windows, check three things with your council: whether your home is listed, whether it is in a conservation area, and whether an Article 4 direction applies.

Most houses, including houses in conservation areas without an Article 4 direction, can usually replace windows without planning permission, as long as the new ones are similar in appearance to the old (Planning Portal).
Flats and maisonettes don't have the same permitted development rights as houses. Identical, like-for-like windows usually don't need permission, but windows that look different may, and if you're a leaseholder you may also need consent from your landlord, freeholder or management company (Planning Portal).
Listed buildings need listed building consent for any significant works, inside or out, including windows (Planning Portal).
An Article 4 direction removes permitted development rights, so even a like-for-like replacement can need an application. Many London councils use them in conservation areas, and the ones that cover windows are listed below.
Barking and Dagenham: has 4 conservation areas, and no Article 4 directions on windows. New directions for the Becontree estate, due to take effect in November 2026, cover porches and side and roof alterations on corner plots, not windows (Barking and Dagenham Council).
Bexley: Has 23 conservation areas. Article 4(2) Directions in Old Bexley restrict window alterations at specified addresses, with additional directions covering window changes and other external alterations in Brook Street, Old Forge Way and Red House Lane (Bexley Council).
Greenwich: has 23 conservation areas. In its Article 4 areas, including the Progress Estate and West Greenwich, you may need permission 'for most works including replacing windows and doors' (Royal Greenwich). The council calls uPVC 'a poor and inauthentic compromise' on the Progress Estate.
Hackney: has 35 conservation areas. Directions in De Beauvoir and St Mark's cover changes to windows and front doors, and newer ones apply in Brownswood, Well Street, Beck Road and Shacklewell Green (Hackney Council).
Havering: has 11 conservation areas. The Gidea Park direction controls alterations to the front and sides of houses, and at Level 2 the rear too (Havering Council).
Lewisham: has 29 conservation areas and Article 4 directions in about 20 of them, covering 'changes to windows' (Lewisham Council). Replacing original windows with uPVC or aluminium on visible elevations 'will not be accepted', though slim double glazing usually is (Lewisham Council).
Newham: has 9 conservation areas. In Durham Road, Romford Road and the Woodgrange Estate, replacing windows needs consent, and Durham Road accepts heritage-style uPVC sashes (Newham Council).
Redbridge: Has 16 conservation areas. Article 4 Directions in Aldersbrook and the Bungalow Estate restrict certain window replacements. A separate direction covering windows and window frames, among other changes, applies to Nos 2 to 48 The Drive, Snaresbrook (Redbridge Council).
Tower Hamlets: Has 58 conservation areas. The council's published list of confirmed Article 4 Directions does not identify any specifically covering window replacements, although individual conservation-area guidance may recommend or restrict changes to historic windows. Many historic properties are statutorily listed, in which case alterations affecting their special character may require listed building consent (Tower Hamlets Council).
Waltham Forest: Has 15 conservation areas, with Article 4 Directions in most of them, as well as a separate Article 4 Direction covering the Highams Park Estate, the borough's only Area of Special Character. Whether replacement windows require planning permission depends on the property's location, status and the scope of the proposed work.
Carrying out work without the necessary consent can lead to enforcement action, potentially requiring the windows to be reinstated at the owner's expense. We check the relevant planning and heritage requirements for every survey and can help with the application process where permission is needed.

Frequently asked questions

Can I fit uPVC windows in an East London conservation area?

It depends on the borough. Lewisham says uPVC or aluminium on visible elevations 'will not be accepted', while Newham's Durham Road guide accepts heritage-style uPVC sashes with run-through horns. Where an Article 4 direction applies, you'll need planning permission first. We check your street at survey.

What windows suit a Becontree house?

Most Becontree houses suit cottage-style casements with a simple glazing-bar pattern. The council has adopted a new design code for the estate, so we check it before quoting.

What windows suit a Victorian terrace in Hackney or Walthamstow?

Sliding sash windows, in timber or uPVC, with the original glazing pattern. Keep the bay, and copy any arched or paired window heads.

Do I need permission to replace windows in a flat?

Often. Identical, like-for-like replacements usually don't need planning permission, but windows that look different may, and rules vary by council. If you're a leaseholder, check your lease, as you may also need the freeholder's or management company's consent.

Do you cover my part of East London?

Yes. We work across all ten East London boroughs, including Hackney, Bow, Greenwich, Blackheath, Walthamstow, Ilford, Romford, Bexleyheath and Dagenham.
