Solar panels on Warrington's New Town homes
Warrington became a New Town in 1968, and the homes built over the next twenty years shape what solar looks like here. Many of them have exactly the kind of roof panels suit. Here is what to check on a house from that era.
How the New Town was built
Warrington was designated a New Town on 26 April 1968. The designated area, about 7,550 hectares, took in three large former public sites: the RAF camp at Padgate, much of RAF Burtonwood and the Royal Ordnance factory at Risley. The members of the Warrington Development Corporation were appointed in March 1969, and its Outline Plan, approved in 1973, set out to grow the town's population from about 120,000 to 200,000. By March 1981 the Corporation had completed about 3,500 rented homes as well as industrial units, alongside private housebuilding. In 1981 it became the Warrington and Runcorn Development Corporation, and it was wound up on 30 September 1989.
The Valuation Office Agency's 2026 count shows the result. Homes built in 1973 to 1982 make up 10.8% of Warrington's stock (England 8.7%), 1983 to 1992 9.9% (6.8%) and 1993 to 1999 7.5% (4.9%). Taken together, 29.1% of the borough's 97,700 dwellings date from 1965 to 1992, against 24.8% nationally.
Why these roofs often suit panels
- Simple shapes. Many estate houses have a plain gable roof with two uninterrupted rectangular slopes, which makes the panel layout straightforward and keeps scaffolding simple on a two-storey house.
- Fewer chimneys. Houses built for central heating often have no chimney stack, or a small one, so there is less shade on the array.
- Mid-life roofs. A roof covering from the 1970s or 1980s may still have plenty of life, but it is worth having its condition checked before panels go on, so you do not have to lift them for re-roofing in a few years.
- Reasonable efficiency already. 74.4% of Warrington homes built between 1983 and 2011 that have an EPC are rated C or better (ONS), so panels add to a fairly efficient home rather than compensating for a leaky one.
What to check on an estate house
Which way the slopes face
Estates were laid out around roads, not the sun, so many houses have east-west roofs. That is fine: in Warrington an east or west slope at 30° makes about 757 kWh per kW a year against 930 for south, and putting panels on both slopes spreads output across the day. The roof output page has the figures for every direction.
Trees planted with the estate
Landscaping that was knee-high in the 1970s can be tall now. Look at what stands to the south, east and west of your roof, including street trees and neighbours' gardens, and ask any installer to show the shading they assumed in the output estimate.
The roof covering and fixings
Ask how the roof hooks will pass your tiles. Interlocking concrete tiles, common on houses of this period, are usually straightforward; some lightweight or less common tiles need specific brackets. The mounting kit should carry an MCS 012 certificate.
Shared and linked houses
Terraces and linked houses on some estates share roof lines with neighbours. Panels on your half of the roof are your decision, but keep the array within your own roof and away from the party wall line, and tell your neighbours before the scaffolding goes up.
Leasehold and estate covenants
Most New Town houses are freehold, but check your title deeds for covenants about alterations, and if your home is leasehold, read the lease. Former Development Corporation and council homes bought under right to buy are freehold in most cases, while flats are usually leasehold.
Birchwood and the network operator
Warrington is unusual in having two electricity network operators. Overlaying the official licence-area map on the borough's wards suggests that Birchwood lies almost entirely in Electricity North West's area, along with much of Culcheth and Glazebury and part of Rixton and Woolston, while the rest of the borough, including the western New Town estates, is SP Energy Networks. It makes no difference to you in practice, as long as the installer notifies the right company; see grid connection.
Typical systems
| House | Usual roof | Typical system | Output a year (south, 35°) |
|---|---|---|---|
| Terraced or linked house | Narrow gable, one usable slope | 2.5–3.5 kW | about 2,340–3,280 kWh |
| Semi-detached | Gable, one or both slopes | 3–4.5 kW | about 2,810–4,220 kWh |
| Detached | Larger slopes, often a garage roof | 4–6 kW | about 3,750–5,630 kWh |
| Bungalow | Low, wide roof | 3–4 kW | about 2,810–3,750 kWh |
System sizes are typical ranges for these roof shapes, not survey results. Output: PVGIS 5.3 for central Warrington before shading; east or west slopes make about four fifths of these figures.
Warrington has more bungalows than England on average, 10.3% of homes against 9.0% (VOA). Their low roofs are easy to work on but more easily shaded by hedges and neighbouring houses.

Questions about New Town homes
Are New Town houses in Warrington good for solar panels?
Often, yes. Many houses built between 1965 and 1992 have simple gable roofs in sound condition, which makes panels quicker and cheaper to fit. Check the direction of the main slope, any shade from trees planted when the estates were built, and how the roof tiles are fixed.
My estate house faces east-west. Is solar still worth it?
Usually. In Warrington an east or west roof at 30° makes about 757 kWh per kW a year, about four fifths of a south roof, and spreads the output across the morning and evening.
Who is the network operator for Birchwood?
Electricity North West covers most of Birchwood, while most of the rest of Warrington is SP Energy Networks. Your installer notifies or applies to whichever covers your address.
