Heat pumps for landlords in Norwich

Norwich has more flats than most cities

Norwich has 17,351 privately rented households out of 64,457, which is 26.9% (2021 Census). Owner-occupiers are 42.1% and social tenants 30.3%, the highest social share among the cities on this site.

The property mix is close to an even split between terraces and flats. Terraced homes are 32.0% of households (about 20,600) and purpose-built flats 30.2% (about 19,500). Semi-detached homes are 21.8%, detached 10.3% and converted houses 3.1%. Only London, Southampton and Cambridge on this site have a higher flat share.

The first question for a Norwich landlord is therefore often “is this a flat?”, and the answer changes the whole decision:

Property	The first question
Flat in a purpose-built block	Will the freeholder consent, and is there space for a unit within the 0.6 cubic metre limit?
Terraced house	Is there a rear position for one unit that meets the 37.0 dB(A) noise limit?
Semi or detached house	Is the fabric good enough for low-temperature heat?
House in a conservation area	Does the position face the street, and do the extra limits apply?

These percentages cover all households, not only rented ones, so check your own property.

Heating in Norwich

Mains gas heats 75.7% of homes, about 48,800 households. Electric-only heating is 10.6%, about 6,800. District heating is 2.4%, about 1,500, which is higher than most cities here. Oil is 0.2% and no central heating 1.5%.

Three points follow:

• The common swap is gas to heat pump, where the sums are tight. Gas is 7.97p per kWh and electricity 26.32p under the Ofgem cap for 1 October to 31 December 2026, so a heat pump needs a good SCOP to cut the tenant’s bills.
• Electric-only flats are the strong case. A heat pump at SCOP 3.0 uses about a third of the electricity of direct electric heating for the same heat. See storage heaters vs heat pumps.
• The £9,000 off-gas rate is rare in the city. It needs oil or LPG with no mains gas connection. At 0.2% on oil, plan on £7,500. For off-gas homes elsewhere, see replacing oil or LPG heating in a rental.

If your building is one of the 2.4% on a district heating system, ask the operator about the connection terms before replacing anything.

Worked example (modelled, not a real project)

Inputs: a two-bedroom flat using 4,000kWh of heat a year (an assumption for a flat with neighbours on two sides), Ofgem cap unit rates for 1 October to 31 December 2026 (electricity 26.32p, gas 7.97p per kWh), direct electric heating at 100%, a gas boiler at 90% and a heat pump at SCOP 3.0 or 3.5. Standing charges are left out.

Heating	Fuel needed	Fuel cost a year
Direct electric heating	4,000kWh electricity	about £1,053
Gas boiler, 90%	4,444kWh gas	about £354
Heat pump, SCOP 3.0	1,333kWh electricity	about £351
Heat pump, SCOP 3.5	1,143kWh electricity	about £301

Against direct electric heating the tenant saves about £700 a year. Against gas the saving is small, about £50 at best. In a gas-heated flat the heat pump case rests on the EPC, not the bills, and the installed cost is the same whichever system it replaces.

Warm Homes: Local Grant in Norwich

GOV.UK lists Norwich City Council with £5,504,964 under the Warm Homes: Local Grant, with no consortium partners, more than Leicester’s £4,507,699 or Sheffield’s £4,006,008. The council’s own page, read on 8 October 2026, says:

• It covers privately owned or rented homes with an EPC of D, E, F or G.
• Up to £30,000 worth of works, including insulation, ventilation and low-carbon heating such as heat pumps.
• Three income routes: a postcode ranked 1 or 2 on the Index of Multiple Deprivation, a qualifying benefit, or household earnings under £36,000 before tax.
• Applications go through E.ON, the council’s partner, or the GOV.UK form, and the scheme was open.

The council has separately described £4.7 million secured to improve 330 private homes. For a landlord, the national terms matter most: the first property is fully funded and later ones need a 50% contribution, you declare that rent will not rise because of the funded work, and an EPC F or G rental needs a registered exemption first. Read the Warm Homes Local Grant page before you apply, and ask the council which terms it applies.

HMO licensing in Norwich

Norwich City Council’s HMO licensing page describes the national mandatory scheme: a licence is needed where 5 or more tenants form 2 or more households. The fee is £1,141 in total, £636 on application (non-refundable) and £505 once the application is processed, for a 5-year licence. In February 2025 the council consulted on an updated HMO licensing policy and said it oversees about 1,000 licensed HMOs.

The council’s licensing page does not describe a selective or additional licensing scheme. A licence carries conditions, so if your property is licensed, ask the council whether a heating change affects them.

Conservation areas in a historic city

Norwich City Council says there are 17 conservation areas in Norwich, protected by law. In a conservation area the heat pump permitted development rights carry extra limits, and a listed building needs consent. Check the council’s conservation area maps before agreeing a unit position.

Norwich’s climate programme and heat network

The council’s plan is the Climate Responsive Norwich Programme 2026 to 2035. It sets net zero council operations by 2030 and net zero Norwich by 2045. The site panel shows the council’s 2030 target; the citywide target is 2045. Neither is a duty on landlords.

The council says it is exploring a citywide heat network, and Norwich is in the government’s heat network zoning pilot. Nothing published sets a date for private rented homes to connect, so a heat network is not a reason to delay a decision on a typical flat or terrace.

EPC C by 2030

Today the legal minimum is EPC E, with a £3,500 cost cap including VAT. The government plans EPC C by 1 October 2030 with a £10,000 cost cap per property, but the regulations have not been laid. Read EPC C 2030 and your heating choice, the cost cap and exemptions and does a heat pump improve an EPC rating. In a Norwich flat, controls and insulation are often cheaper EPC gains than a new heating system.

Grants for Norwich landlords

• Boiler Upgrade Scheme: £7,500 for an air-to-water or ground source heat pump. Landlords are eligible, and an MCS installer applies for you. See the BUS page for landlords.
• Warm Homes: Local Grant: see above.
• Warm Homes Loan Scheme: a lender loan, not a grant.

The Boiler Upgrade Scheme excludes homes already given government heat pump funding, so decide which route fits before applying.

When a heat pump is the wrong answer

• A flat where the freeholder will not consent or there is nowhere for the unit. See heat pumps for flats.
• A building already on a district heating system.
• A gas-heated home with thin insulation where tenants would pay more.
• A conservation area position facing the street without checking the limits first.
