How to Budget for a Heat Pump in Leicester (2026 Prices)

Step 0: check whether you would pay anything at all

Before pricing a heat pump, it is worth five minutes to see if someone else will pay for it.

Leicester City Council has more than £4.5 million of Warm Homes: Local Grant funding. It pays for insulation, solar panels and low-carbon heating such as air source heat pumps in privately owned homes (owner-occupied or privately rented) where:

• the household income is below £36,000 a year, and
• the home has an EPC rating between D and G.

Eligible households pay nothing. Leicester has a younger and lower-income population than many English cities, so a meaningful share of homes in the city could qualify. The scheme runs in phases until March 2028.

One catch for people just outside the city boundary: Leicestershire County Council has paused new applications to its own scheme because of demand. If you live in Oadby, Wigston or Birstall, you can still register interest through the government’s Warm Homes: Local Grant service so you are contacted when funding opens again.

If you don’t qualify, the steps below build a realistic budget.

Step 1: the heat pump itself

The outdoor unit, its controls and commissioning usually make up 40–55% of the total. Size is set by your home’s heat loss, measured room by room in the survey.

Typical Leicester home	Heat loss	Unit size	Unit budget
Two-bed terrace, Clarendon Park or Highfields	4–6 kW	5–6 kW	£5,000–£6,000
Three-bed interwar semi, Knighton or Western Park	6–8 kW	7–8 kW	£5,500–£6,500
Four-bed Edwardian villa, Stoneygate	9–13 kW	10–12 kW	£7,000–£8,500

Leicester’s winters are colder than the South West’s. The nearest long-running Met Office station, at Sutton Bonington, averages a January overnight low of about 1.9°C. Installers design for a cold day near freezing, so don’t be surprised if your unit is a size up from a similar house in Bristol or Cornwall.

Step 2: a hot water cylinder

Heat pumps heat water into a stored cylinder rather than on demand like a combi boiler. Expect £1,600–£2,400 for a 150–250 litre heat pump cylinder, fitted.

In Leicester’s terraces, finding room for the cylinder is often the hardest part. Common answers are the old airing cupboard, a cupboard built over the stairs, or the loft with a properly supported platform.

Severn Trent’s water in Leicester is hard — typically somewhere around 220–280 mg/l of calcium carbonate depending on your street. Ask for a cylinder whose coil is rated for heat pumps, and think about a scale reducer if limescale is already a nuisance in your kettle.

Step 3: radiators

Heat pumps run the heating water cooler than a gas boiler — usually 45–55°C rather than 70°C. Some radiators then need to be larger to keep each room warm.

• Most interwar and post-war semis: one to three upgrades, £400–£1,200
• Victorian terraces with solid nine-inch brick walls: three to five upgrades, £1,200–£2,200
• Large villas: five or more, £2,000–£3,500

If your house still has microbore (8–10 mm) pipework from a 1970s or 1980s heating upgrade, some of it may need replacing to carry enough flow. That can add £500–£2,000 and is one of the most common surprises.

Step 4: installation and extras

Item	Typical range	When it applies
Pipework, labour, concrete base	£1,500–£3,000	Always
Electrical circuit / consumer unit	£300–£800	Most homes
Supply upgrade from the network operator	Usually £0	Rare; National Grid Electricity Distribution covers the East Midlands and assesses this
Oil or LPG tank removal	£400–£900	Off-gas homes only
Planning application	£0–£600	Conservation areas (front elevation), listed buildings
Acoustic enclosure or extra siting work	£300–£1,000	Tight back yards close to neighbours

Leicester has 25 conservation areas, including Stoneygate, Castle Gardens and Ashleigh Road. A unit in the back garden is normally covered by permitted development even there; one fixed to a wall facing the street is not.

The noise rule matters more in Leicester than in many places. In a row of terraces with yards a few metres wide, the unit has to calculate at no more than 37 dB at the neighbour’s nearest window. A good installer picks a quiet unit and siting that passes, rather than leaving you with a planning application.

Step 5: add it up and subtract the grant

Here is how the steps combine for three common Leicester homes.

	Clarendon Park terrace	Knighton semi	Stoneygate villa
Heat pump	£5,500	£6,000	£8,000
Cylinder	£1,700	£2,000	£2,300
Radiators	£1,600	£800	£2,800
Installation and extras	£2,400	£2,000	£3,200
Gross	£11,200	£10,800	£16,300
Boiler Upgrade Scheme	−£7,500	−£7,500	−£7,500
Your share	£3,700	£3,300	£8,800

For comparison, the national median for heat pumps installed under the scheme in 2025/26 was £13,041, with most jobs between £8,000 and £14,000.

The £7,500 grant is open to any homeowner or private landlord replacing a fossil-fuel or electric heating system with an MCS-certified installer — no income test. Homes currently heated by oil or LPG get £9,000 on applications from 21 July 2026 to 31 March 2027. VAT on heat pump installation is 0% until March 2027.

Step 6: what it will cost to run

At the price cap for October to December 2026, gas costs about 8p per kWh and electricity about 26p. A heat pump turns each unit of electricity into roughly three to four units of heat, so it breaks even with a modern gas boiler at a seasonal efficiency of about 3, and saves money above that — more on a heat pump tariff with cheaper off-peak electricity. The running cost guide has worked examples.

Before you sign

Compare quotes line by line, not just the bottom figure. A cheap quote that leaves out radiators or microbore replacement isn’t cheaper once the extras arrive. Our hidden costs guide lists every line to check, and the BUS eligibility guide confirms whether your home qualifies for the grant.
