Heat pumps for landlords in Birmingham

What the census says about Birmingham’s rented homes

Birmingham had 423,455 households at the 2021 Census, and 95,719 of them (22.6%) rented privately. Owner-occupiers were 52.7% and social tenants 23.5%.

The housing stock is mostly ordinary family housing. Semi-detached houses are 35.6% of homes, about 150,700 households, and terraced houses are 27.8%, about 117,700. Flats make up 21.0%, converted or shared houses 2.9% and detached homes 11.2%.

Measure (Census 2021)	Birmingham
Households	423,455
Renting privately	22.6% (95,719)
Semi-detached	35.6%
Terraced	27.8%
Flats	21.0%
Detached	11.2%
Converted or shared house	2.9%
Mains gas central heating	74.2%
Electric-only central heating	11.7%
District heat	0.6%
Oil	0.1%

Mains gas serves 74.2% of homes, about 314,200 households. Electric-only heating covers 11.7%, about 49,500 households, and district heat only 0.6%. The typical Birmingham landlord decision is therefore a gas boiler in a semi or terrace, and the real question is whether to replace it with a heat pump or keep it and improve the fabric.

The arithmetic for a gas semi

Start with the break-even. Gas heat from a 90% efficient boiler costs 7.97 / 0.9 = 8.86p per kWh. Electricity is 26.32p per kWh (Ofgem cap, 1 October to 31 December 2026). A heat pump has to reach a seasonal efficiency (SCOP) of 26.32 / 8.86 = 2.97 just to match gas.

Worked example (modelled, not a real project). A three-bedroom semi using 12,000kWh of heat a year, the illustrative load used across this site.

Option	Calculation	Annual fuel cost
Gas boiler, 90%	12,000 / 0.9 x 7.97p	£1,063
Heat pump, SCOP 3.0	12,000 / 3.0 x 26.32p	£1,053
Heat pump, SCOP 3.5	12,000 / 3.5 x 26.32p	£902

A heat pump saves £10 a year at SCOP 3.0 and £161 at SCOP 3.5. Against an Energy Saving Trust typical cost of around £12,000 before grant, less the £7,500 Boiler Upgrade Scheme grant, the net cost is about £4,500. At £161 a year that is a 28 year payback on running costs alone, so a Birmingham gas semi does not justify a heat pump on bills.

It can still be justified on compliance. The government has said it will require EPC C by 1 October 2030 with a £10,000 cost cap, but the regulations are not yet made. If the home sits at D or E and fabric measures cannot reach C, the heating system may be the route. The EPC C by 2030 guide and the EPC deadline checker set out the dates. A modelled sum is no substitute for a survey by an MCS installer.

Licensing shapes the decision in Birmingham

In Birmingham two licensing schemes can apply alongside any works plan. The council’s selective licensing covers 25 of the city’s 69 wards. It started on 5 June 2023, each licence costs £700 and lasts up to 5 years. Landlords who fail to license risk a civil penalty of up to £40,000. A property already licensed as an HMO, one managed directly by an educational establishment or one let by a registered social landlord does not need a selective licence.

Separately, since 5 June 2023 a smaller HMO, with 3 or 4 occupants from 2 or more households sharing facilities, needs an additional licence, at £755 a property. Both application forms ask for the current electrical installation inspection and test certificate and, where there is gas, the most recent gas safety certificate.

That has two practical effects. First, a landlord who removes gas altogether still needs the electrical certificate up to date, so schedule the heat pump around inspection dates. Second, swapping a gas boiler for a heat pump in an HMO may take that appliance out of the annual gas safety check. Read landlord gas safety certificates and heat pumps for what changes and what does not.

Grants. Birmingham is outside the national Warm Homes: Local Grant. The DESNZ policy guidance (updated June 2026) says the West Midlands Combined Authority received its allocation through an integrated settlement, so it and its member councils, Birmingham City Council included, cannot take part in the national scheme. The combined authority’s own landlord page offers grants covering 70% of the cost for up to 4 properties and 50% from the fifth, for homes rated EPC D or below in Castle Vale, Balsall Heath, Sparkbrook, Tyseley or Bromford. Tenants may face income or benefit checks depending on the postcode. The measures it lists are insulation, high energy storage heaters, hot water cylinder insulation, solar panels and ventilation, not heat pumps, so ask the combined authority whether a heat pump is in scope before you plan around it.

Conservation areas. Birmingham has 29 recognised conservation areas. Article 4 directions apply in some, including Austin Village, Bournville Village, part of Edgbaston, Greenfield Road, High Street Sutton Coldfield, Moor Pool Harborne, Moseley, Old Yardley, Selly Park, Selly Park Avenues and St Agnes. The council says even minor residential alterations there, such as a porch, replacement windows or re-roofing, need planning permission. Whether an outdoor unit is caught depends on the wording of each direction, so ask the council before you book.

Net zero plan. The council declared a climate emergency in 2019 and aims for net zero by 2030, or as soon as possible afterwards. Its annual net zero report, published in January 2023, put domestic housing at 36% of city carbon dioxide emissions, ahead of transport at 34%. The figure is dated, but it shows why housing sits at the centre of the council’s plans.

Heat networks. Birmingham took part in the government’s heat network zoning pilot (list updated 25 November 2025). District heat serves only 0.6% of homes, about 2,500 households, so most landlords can ignore it, but anyone in the city centre should ask the building manager.

When a heat pump is the wrong answer in Birmingham

• The home is gas heated, the fabric is poor and the EPC gap is small. Loft and cavity insulation may lift the rating for less money.
• The tenant is on a tight budget and the system will run at SCOP 3.0 or lower. They pay the electricity bill and may see no saving.
• An HMO with several tenants on a shared supply, where billing for electricity is unclear. Sort the billing first.
• The property is in an Article 4 conservation area and the only unit position is on a front elevation.
