Where the terraces are
The 2021 Census found 37.9% of Liverpool households living in a terraced house, well above England's 23%, while detached houses made up just 8.2% (ONS). On the wards used at the Census, the terraced share was highest in County (75%), then Old Swan (65.5%), Anfield (61.1%), Speke-Garston (56.3%) and Picton (52.4%).
Many of those streets are old: 30.9% of Liverpool's properties were built before 1919 (VOA 2026). They range from small two-up two-downs to bay-fronted rows with attic rooms, and the differences show up on the roof.
Two slopes, opposite ways
A through-terrace owns the slope over the street and the slope over the yard, so the two always face opposite directions, and one of them normally points somewhere into the southern half of the compass. PVGIS figures for Anfield show what each pairing gives (PVGIS 5.3):
| Street runs | Better slope | kWh | Other slope | kWh |
|---|---|---|---|---|
| East–west | south | 965 | north | 509 |
| North-west to south-east | south west | 913 | north east | 581 |
| North-east to south-west | south east | 899 | north west | 595 |
| North–south | west | 766 | east | 749 |
On a north–south street, neither slope faces south, but both are usable, and splitting panels across them spreads output through the day. In Liverpool the west slope edges the east. Try your own pair on the rooftop estimator.
Stacks, offshoots and dormers
Terrace roofs are narrow, and what sits on them decides how many panels fit. Chimney stacks often stand on both party walls, and a shared stack can shade the nearest panels for part of the day. A two-storey rear offshoot, common on Victorian terraces, can shade the main back slope in the morning or evening depending on which side it sits. Loft conversions add dormers and roof lights. Ask for a layout drawing showing each panel against these obstacles, and an estimate of the shading loss in kWh.
Where shade falls on part of the array, optimisers or microinverters stop one shaded panel holding back the rest; on a clear slope they add cost for little gain.
Scaffold and access
On a terrace the scaffold usually stands on the pavement at the front, or in a narrow yard or alley at the back. Scaffold on the highway needs a licence from the council, which the scaffolder normally applies for. Parked cars, bin days and the neighbours' front doors all need planning. Make sure the quote says where the scaffold goes, that the licence is included, and how long the scaffold will stand.
On streets inside a conservation area, the Article 4 directions that cover most of them include alterations to roofs and roof coverings (Liverpool City Council). The council's page does not mention solar specifically, so ask the planning team before committing; see planning and Article 4.
Small systems and the price per kW
A small roof means a small system, and small systems cost more per kW because scaffold, inverter, electrics and certification cost much the same regardless. In 2025/26, MCS-certified systems up to 4 kW in the North West averaged £2,021 per kW and those from 4 to 10 kW £1,768 (DESNZ). A 2.5 kW array at the smaller-system average would cost about £5,050 by our arithmetic, and make about 2,413 kWh a year on a south slope in Anfield. The costs page has the full range.
The EPC on a terrace
Of Liverpool's terraced homes with an EPC, 47.8% reach band C or above, against 55.6% of semis and 75.3% of flats (ONS). Panels help a rating, but for an older solid-walled terrace, insulation and draught-proofing usually do more for comfort and bills. Households who qualify for the council's Warm Homes: Local Grant may get both through one assessment; eligibility and its current status are on help with the cost. The average Liverpool terrace sold for £178,929 in August 2026 (UK HPI); we make no claim about what panels add to a sale price.
Terraces and the help on offer
Only 47.8% of Liverpool's terraced homes with an EPC reach band C (ONS), so most of them meet the council grant's EPC test, which looks for band D to G. The household still has to qualify, on income below £36,000, a means-tested benefit or a qualifying postcode, and the council says the scheme is oversubscribed for its second year (Liverpool City Council). Rented terraces are the landlord's decision, under the council's licensing scheme for 1 April 2022 to 31 March 2027 (Liverpool City Council). See paying for solar for every route.
An Anfield terrace, worked through
Take a two-up two-down in Anfield whose slopes face east and west, with a stack at each end and a back offshoot. If 1.5 kW fits on each slope, PVGIS gives about 2,273 kWh a year between them; at the North West mean for small systems that is about £6,050 (our arithmetic from PVGIS 5.3 and DESNZ), though a real quote for a roof this small will often sit above the mean per kW. Check the figure on the estimator and the price on the costs page.
