Orpington lies in the south-east corner of London, where the suburbs give way to the Kent countryside and the M25 runs just to the south. It is the largest town in the London Borough of Bromley outside Bromley itself, and most of its homes date from the railway-led building boom of the 1920s and 1930s. Inspired Glazing designs, makes and fits aluminium windows, sliding and bifold doors, UPVC windows and composite doors for homeowners in Orpington and the neighbourhoods around it.
What Orpington homes are like
Orpington station opened in 1868, bringing the first new housing to Crofton and Broom Hill. The real growth came after the station was expanded in 1904, with house building peaking between the wars. That history shapes what we see today:
- Inter-war semis and detached houses make up much of the town. Many have bay windows and small top-lights, and they are often on their second or third set of windows.
- Older buildings around the High Street and The Priory, a medieval hall house beside the gardens where the River Cray rises, form the historic core.
- Post-war and later estates on the fringes, where wider garden doors and practical, low-maintenance windows are the main requests.
Planning and conservation areas in Bromley
Planning in Orpington is handled by the London Borough of Bromley, which has 47 conservation areas. Locally they include The Priory in Orpington, The Covert in Petts Wood and the large Chislehurst conservation area. Bromley’s 2025 appraisal for The Covert, for example, describes neo-Tudor houses whose typical windows are metal casements in timber frames with square or diamond leaded lights, and it encourages owners to keep original proportions and detailing.
That kind of guidance varies from area to area and from house to house. If your home is in a conservation area, is listed or sits in one of Bromley’s areas of special residential character, please check with the London Borough of Bromley before ordering. We are happy to supply drawings, samples and specifications for that conversation.
Areas we cover around Orpington
Petts Wood
Laid out from the late 1920s by developer Basil Scruby, Petts Wood is known for its mock-Tudor houses. Slim aluminium with applied glazing bars can respect that style where the council is happy with modern frames.
Chislehurst
Larger Victorian and Edwardian houses set around the commons, many within the conservation area, where careful choice of profile and colour really matters.
Farnborough Village and Green Street Green
Farnborough keeps an older village centre to the south-west of the town, while Green Street Green, to the south-east, is largely twentieth-century housing that suits aluminium or UPVC replacements.
Biggin Hill
On high, open ground near the Kent border, Biggin Hill has a mix of bungalows and family homes, where well-sealed windows and sturdy doors make a noticeable difference.
Products for Orpington homes
Our core aluminium window is the Reynaers SlimLine 68. Reynaers lists Classic and Ferro design variants, describes ultra-slim sightlines in the outward-opening version, and quotes PAS 24 and Secured by Design ratings (Reynaers SlimLine 68). For inter-war bays, the slim frames help keep the curve of the bay looking light. We also fabricate Cortizo and Alunet windows; see our aluminium windows page for more.
At the rear, the Reynaers ConceptPatio 130 sliding door suits wide extension openings, and our bifold doors use Smart Visofold and Cortizo systems. For a lower-cost option, our UPVC windows use Advance 70, and a composite door is a popular front-door upgrade.
Survey and installation from Fifield
We do not have an office in Orpington. Our workshop is at Coningsby Farm in Fifield, near Windsor, about 55 to 60 miles away by road. The drive usually takes a little over an hour round the M25, leaving at junction 4. At the survey we measure every opening, check the condition of the brickwork and bays, talk through styles and colours, and note parking and access. Your frames are then made in our own workshop and fitted by our own team, who remove the old units and clear up afterwards. Lead time is from 10 days and our guarantee lasts 10 years.
For nearby towns across the border, see our windows and doors in Kent page.

Frequently asked questions
Who handles planning for windows in Orpington and Petts Wood?
The London Borough of Bromley. It has 47 conservation areas, including The Priory in Orpington, The Covert in Petts Wood and Chislehurst, and some neighbourhoods have extra local guidance. Listed buildings need Listed Building Consent for window changes. Check with the London Borough of Bromley before ordering, and we can supply drawings to help.
Can you replace windows on a mock-Tudor house in Petts Wood?
In many cases, yes. Petts Wood’s neo-Tudor houses often had metal casements with leaded lights, and slim aluminium frames with applied glazing bars can respect that look. Some streets, such as The Covert, have conservation-area guidance favouring original detailing, so check with the London Borough of Bromley first. We will discuss the options at the survey.
What is the best window for a 1930s bay in Orpington?
Slim aluminium frames, such as the Reynaers SlimLine 68, keep the bay looking light and let in plenty of daylight, and the Classic or Ferro variants suit different 1930s styles. UPVC is a lower-cost alternative that suits many inter-war homes well. We can quote both so you can compare looks and price.

Our workshop is in Fifield, near Windsor, around 55 to 60 miles from Orpington by road. The journey usually takes a little over an hour round the M25, leaving at junction 4. We do not have a local branch, but our own team makes, delivers and fits everything, from survey to the final clean-up.
