For double glazing in Havering, Inspired Glazing surveys, makes and fits aluminium windows and doors, UPVC windows, composite doors and conservatories for houses across Romford, Hornchurch, Upminster and the estates around them. Our aluminium frames are fabricated in our own workshop at Fifield, near Windsor, and fitted by our own team. We have no east London branch: Havering is roughly 50 to 60 miles from Fifield by road depending on whether we take the M25 or cross London, usually an hour and a quarter to an hour and a half, so we plan surveys and installation days in advance around that journey.

A borough built mostly between the wars
Havering is mainly suburban. More than half of the borough is Metropolitan Green Belt, and most of its homes went up in a few big waves. Hornchurch’s population rose by 335 per cent between 1921 and 1938 as Londoners moved out along the newly electrified District line, and Upminster has been part of the continuous built-up area since the 1930s. The result is street after street of interwar semis and short terraces, with older and newer pockets in between.
The older layers matter too. Emerson Park began in 1895, when 200 acres of the Nelmes estate were sold for around 200 larger homes, and it still has bigger plots than the denser estates that followed. Elm Park was launched by Costain in 1933 as a garden city of planned houses, with about 2,600 built by 1939 and over 1,000 council houses added after the war. To the north, Harold Hill was built by the London County Council between 1948 and 1958: 7,631 permanent homes, mostly brick terraces with some flats.
Gidea Park and Havering’s other conservation areas
Gidea Park is the borough’s most distinctive suburb. It began as the Romford Garden Suburb, an exhibition of 159 houses and cottages built in 1910 and 1911 by more than 100 architects, and a second exhibition in 1934 and 1935 added 35 mostly flat-roofed modern houses around Heath Drive and Brook Road. Havering Council has an Article 4 direction that withdraws certain permitted development rights from houses in the Gidea Park conservation area, so window and door changes there need care.
The borough has 11 conservation areas in all, including Romford, Rainham, Corbets Tey, Cranham, Havering-atte-Bower, North Ockendon, Langtons and the RAF Hornchurch site. If your home is in one of them, or is listed, check with Havering Council before choosing new windows. We can supply drawings and product details to support an application, but we will never guess at what the council will accept.
Matching products to Havering houses
- Interwar semis in Hornchurch, Elm Park and Upminster: our UPVC windows and doors on the Selecta Advance 70 system suit bay-fronted semis and are often the best-value replacement for tired 1990s frames.
- Harold Hill and Collier Row terraces: UPVC casements and a composite front door make a practical, low-maintenance upgrade for brick terraced houses.
- The 1930s modern houses at Gidea Park and larger Emerson Park homes: slim aluminium windows, including the Reynaers SlimLine 68 outward-opening casement, keep thin sightlines on white-rendered or architect-designed houses.
- Gardens across the borough: Havering’s generous back gardens suit aluminium bifold doors from Smart Visofold or Cortizo, or Reynaers ConceptPatio 130 sliding patio doors.
- Extra space: conservatories, orangeries, porches and roof lanterns for semis with room to extend.
We do not make timber windows. Where a woodgrain look is wanted, woodgrain-finish UPVC or aluminium, or a composite door, is the alternative.

From survey to fitting day
Because the drive from Fifield is a long one, we book Havering surveys in advance. The surveyor measures every opening, looks at the brickwork and any existing bays, and talks through glass, colours and hardware. You then get a written quote. Aluminium windows start from £400, with lead times from 10 days, and every installation carries our 10-year guarantee. For a fuller picture of costs, see our double glazing cost guide, and for permission questions, our guide to planning permission for replacement windows.
Once you approve the design, aluminium frames are made in our Fifield workshop and the fitting team travels out on a booked date, removing the old frames, installing the new ones and finishing the reveals before they leave.

Frequently asked questions
Do I need planning permission for new windows in Gidea Park?
Possibly. Gidea Park is a conservation area and Havering Council has an Article 4 direction removing certain permitted development rights from houses there. That can bring window and door changes under planning control. Check with Havering Council before ordering. We can provide drawings and product details for any application, and we will not start work until you know where you stand.
Can you replace windows on an ex-council house in Harold Hill?
Yes. Harold Hill was built by the London County Council between 1948 and 1958, mostly as brick terraced houses, and many are now privately owned. If you own the freehold, replacing windows is normally straightforward. If the home is leasehold or still managed by the council, check whether you need landlord consent before we order.
How far does your team travel to reach Havering?
Our workshop and team are based at Fifield, near Windsor. Havering is roughly 50 to 60 miles away by road depending on the route, usually an hour and a quarter to an hour and a half. We have no local office, so we plan surveys and installation days in advance around the journey.
What suits a 1930s bay-fronted semi in Hornchurch or Upminster?
For interwar semis, UPVC windows on the Selecta Advance 70 system are a practical choice: they can be made up for curved and angled bays and need little maintenance. If you want slimmer frames and a more modern look, aluminium casements are the alternative. Our surveyor will measure the bay and explain the options and costs for each.
How much do aluminium windows cost in Havering?
Our aluminium windows start from £400 each. The final price depends on size, glass, colour and how many windows you replace in one go. Replacing several windows at once is usually the most efficient way to plan a visit from Fifield. Book a free survey and you will get a written quote for your home.
