Heat Pump Cost for a 2-Bed Bungalow: Full 2026 Breakdown

This site has two bungalow pages, and the difference between them is money rather than wording. Our main bungalow guide is built around a three bedroom bungalow of roughly 101 square metres, which our model puts at 10,350 kWh of annual heat demand, a heat pump of about 9.5 kW and £11,000 to £15,500 before the grant. This page is the two bedroom case: roughly 70 square metres, 8,280 kWh, about 7.5 kW and £10,500 to £15,000 before the grant. On the same insulation level the median job is about £700 cheaper and the running cost is £139 a year lower on a heat pump tariff.

Use floor area rather than the bedroom count to decide. Two bedrooms plus a large through lounge can reach 90 square metres and behave like the three bedroom case; two small bedrooms, a bathroom, a kitchen and one living room is the house described here. Our heat pump calculator runs your own figures through the same model.

The best price evidence is what installers actually charged. Every heat pump paid for through the Boiler Upgrade Scheme in England and Wales has its installed cost recorded on its MCS certificate, and the government publishes the median by heat pump size. In 2025/26 the median air source installation cost £12,164 at 6 to 8 kW, across 8,054 homes, and £12,686 at 8 to 10 kW, including the system, labour and VAT, before the grant. Our heat model sizes a typical 2-bed bungalow at 7.5 kW and reads the scheme's median for that size.

Only £600 separates the medians of the top and bottom rows, £12,000 against £12,600, and that is the point most quotes miss. Insulation barely moves the price of a small heat pump, because the recorded costs for small units sit close together. What it moves is the flow temperature the system can hold, and therefore the running cost. Most of this guide is about that.

Two cheap outcomes are common here: a system boiler with an airing cupboard cylinder solves the cupboard problem already, and a usable crawl space lets the installer drop pipework under the floor rather than chase walls. The expensive outcome is a bungalow that needs most of its radiators replaced, which can take the job above the typical range if that work is not in the quote.

A two bedroom bungalow is not a small house on the heating bill. It sits between a 2-bed end terrace and a 3-bed bungalow, and it costs more to heat than any other two bedroom home except a detached house.

A two bedroom bungalow uses 31% more heat than a two bedroom mid terrace and 23% more than a two bedroom semi. It is more expensive to heat than a 2-bed terrace, semi or flat, and close to a 2-bed detached house. That is not a quirk of the model. It is geometry, and it is why this page exists. Note the middle column too: on standard electricity every one of these homes costs more to run on a heat pump than on gas at average insulation.

Stack a house and you halve two of its surfaces. Spread it out and you double them. The heat model behind this site puts a two bedroom home at roughly 70 square metres of floor area. Over two storeys that is 35 square metres of roof and 35 of ground floor. As a bungalow it is 70 square metres of each, because every room sits directly under the loft and directly on the ground.

Walls go the other way, but not far enough to compensate. A 70 square metre bungalow on a 10 metre by 7 metre footprint has roughly 82 square metres of external wall; a two storey house of the same floor area has about 115. So the bungalow trades roughly 33 square metres of extra wall for 70 square metres of extra roof and floor. Its total heat losing envelope is about 222 square metres against about 185, for exactly the same living space.

The split matters as much as the total:

• In a 2-bed bungalow the loft floor is roughly a third of the whole heat losing envelope.
• In a two storey 2-bed house the roof is under a fifth of it.
• The ground floor is the same story again, and it is the surface almost nobody insulates.
• Walls, the measure most retrofit advice leads with, are a smaller share here than in a house.

The conclusion runs against most general insulation advice. In a two storey house the walls come first. In a two bedroom bungalow the loft and the floor deserve as much attention as the walls. Our insulation calculator ranks the measures for your own property type.

Most two bedroom bungalows need a heat pump of around 6.5 to 8.5 kW. Our model puts a typical one at 7.5 kW, a well insulated one with 270 mm in the loft, filled cavities and double glazing at 6.5 kW, and one with thin 1970s loft insulation, an unfilled cavity or a conservatory running off the radiators at 8.5 kW. That is one to two sizes below a three bedroom bungalow at 9.5 kW, and above a two storey 2-bed terrace at 5.5 kW.

The room by room heat loss calculation decides it, not the bedroom count. Your MCS installer surveys every room, works out its loss on a cold design day and sizes the unit to cover that and your hot water with a small margin. A quote without that calculation was sized by guesswork.

Oversizing is the specific risk at this size, because installers often reach for the unit they fit most. An oversized heat pump costs more to buy and switches on and off more often on mild days. If a unit well above the calculated heat loss is proposed, ask why in writing.

In few other homes does one measure matter as much as loft insulation does in a two bedroom bungalow. The loft floor is roughly a third of the heat losing envelope, the insulation is often the original 1970s or 1980s depth, and the fix is one of the cheapest in the retrofit catalogue.

On our model, moving this house from average to well insulated cuts heat demand from 8,280 kWh to 7,038 kWh. On gas that is £733 down to £623, a saving of £110 a year. On a heat pump tariff it is £557 down to £432, a saving of £125, and the heat pump's seasonal efficiency rises from 2.78 to 3.05 because it can hold a lower flow temperature. That full step includes more than the loft. Measured in real homes, loft insulation on its own, top-ups and bare lofts together, cut gas use by a median 3.2% in the government's NEED data, so the loft is only one part of the step, but it is by a distance the cheapest part.

Three points specific to bungalows. The loft is often in use as storage, because there is no spare bedroom and frequently no garage, so raise boards on loft legs rather than crushing 270 mm of mineral wool under chipboard. A bungalow loft is wide and shallow at the eaves, so corners get missed and ventilation gets blocked; ask for eaves trays. And the hatch and any loft pipework need insulating too. Our DIY loft insulation guide covers doing it yourself, our guide explains how long loft insulation lasts, and on a qualifying benefit free loft insulation may be available.

The ground floor of a two bedroom bungalow is the same 70 square metres as the loft, and in many older bungalows it is suspended timber over a ventilated void with nothing under it at all. It is the second largest heat losing surface in the building and the one that rarely appears on a retrofit quote.

It matters more with a heat pump than with a boiler. A heat pump runs the house at a steady, gentle output rather than heating it in bursts, so draughts through floorboards and cold surfaces at ankle height are more noticeable. Insulating between the joists and sealing the perimeter gap at the skirting can make a room feel warmer at the same thermostat setting. Underfloor insulation costs depend heavily on access, and a bungalow with a decent crawl space is the easy end of the range.

If the bungalow has a solid concrete floor, insulating it means raising floor levels and is rarely worth it alone. Go loft, then draught proofing, then cavity wall insulation if the cavity is unfilled.

The 6 to 9 kW class is the busiest part of the market, and every major manufacturer has a unit in it. These are the models you are most likely to be quoted, with specifications from each manufacturer's own pages.

At this size the brands are close and the design decides the result. Ask for a design flow temperature of 50°C or lower, the seasonal performance the installer expects at that temperature in writing, and an MCS 020(a) sound calculation for the position the unit will actually occupy. R290 units can run hotter, which can save a radiator or two in a 1930s bungalow with small panels. Our heat pump noise guide explains what the decibel figures mean in practice.

A heat pump runs the heating at a lower water temperature than a gas boiler, so radiators have to be larger. A two bedroom bungalow has 5 to 7 radiators and 2 to 3 usually need upsizing, often the living room, the hall and the main bedroom. Bungalows help here: long, low walls under wide windows mean a double panel radiator in the same slot solves many rooms without moving pipework. Our radiator sizing guide explains how installers choose.

You also need a hot water cylinder, and the recorded job costs above include one. With no landing airing cupboard it goes in the hall cupboard many older bungalows still have, the space the old boiler occupied, a utility room or an integral store; the Energy Saving Trust says a cylinder can usually fit in any cupboard at least 80cm by 80cm. Avoid the loft: a full cylinder is very heavy, and 1960s ceiling joists were not sized for it. On a combi there is no cylinder today, so the installer needs somewhere to put one. Our main bungalow guide goes through the cupboard options in more detail.

Pipework is what a bungalow makes simpler. Runs are short and horizontal and nothing drops through a ceiling, so installation is usually quicker than in a two storey house. The exception is microbore, the 8 mm or 10 mm pipe fitted from the 1970s onwards, which restricts flow at heat pump temperatures and usually needs replacing with 15 mm. Ask for pipe sizes at the survey, and insulate any loft pipe run as well as the loft floor.

These figures use the Ofgem price cap for 1 October to 31 December 2026: electricity 26.32p per kWh and gas 7.97p per kWh. Heating oil is 11.3p per kWh, the BoilerJuice UK average of 116.20p a litre on 25 September 2026, and LPG 9.5p, the price our model uses. Electricity carries no VAT from 1 October 2026 to 31 March 2027, so when 5% VAT returns every heat pump figure below rises by about 5%. The worked example is a typical two bedroom bungalow with average insulation and 8,280 kWh of heat demand.

On a standard electricity tariff the heat pump costs more to run than the gas boiler it replaces, by £51 a year, or about £90 once VAT returns to electricity. That is the honest arithmetic at this price cap: at a seasonal efficiency of 2.78, a unit of heat from 26.32p electricity still costs more than one from 7.97p gas through a 90% boiler. Against gas, the whole case for a heat pump in this house rests on moving to a heat pump tariff, where the effective rate falls to around 18.7p and the saving becomes £176 a year, or about £148 once VAT returns. Treat the tariff as a condition of the project rather than a bonus, and read our tariff guide before signing anything.

Off the gas grid the picture is better and does not depend on the tariff. Against oil the heat pump saves £317 a year even on standard electricity and £544 on a heat pump tariff, with oil at 11.3p per kWh, the BoilerJuice UK average of 116.20p a litre on 25 September 2026; oil prices move, so these savings will too. Against LPG it saves £141 and £368. Against an electric boiler or old storage heaters it is not close: £557 against £2,179.

A leakier bungalow is a worse case, not a better one

It is tempting to assume that the harder a house is to heat, the more a heat pump saves. The model says the opposite, and this is one of the clearest examples of it on the site.

The saving falls as the house gets worse: £191, then £176, then £140. Poor insulation hurts a heat pump twice. It raises heat demand, which a boiler also has to meet, but it also forces a higher flow temperature to keep rooms warm, dropping seasonal efficiency from 3.05 to 2.55, and the lost efficiency costs more than the extra demand. The well insulated bungalow is also the only one of the three that is cheaper to run on standard electricity, at £607 against £623 on gas. Insulating first is not a nice extra before a heat pump in this property type. It goes a long way to deciding whether the heat pump has a running cost case at all. Our running costs guide works the same comparison across every house type.

The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump in England and Wales. Until 31 March 2027, a home heated by oil or LPG that has no mains gas connection gets an extra £1,500, making £9,000. On a two bedroom bungalow that takes the whole job from £10,500 to £15,000 down to £1,500 to £6,000. Your MCS certified installer applies and it comes off the invoice. Regulations in force from 28 April 2026 extended the scheme to 2030 and removed the need for a valid EPC, and installations carry 0% VAT until 31 March 2027. The bungalow qualifies provided you own it and the heat pump replaces fossil fuel heating. A hybrid that keeps the oil boiler as backup does not qualify. Read our BUS grant guide for the detail.

Bungalows are common off the gas grid, in villages and on the edges of towns where the main never arrived. If the bungalow is in England with an EPC of D to G, and the household income is usually £36,000 or less, someone receives certain benefits or you live in an eligible postcode, the council run Warm Homes: Local Grant can pay for insulation, an air source heat pump and solar panels at no cost to you, where the council has funding. You apply through the council rather than the installer, so check it before accepting a quote. The earlier Home Upgrade Grant is closed to applications. Our grant checker covers the rest.

On mains gas the running cost case is thin, and the decision is mostly about getting off gas. The government puts the average cost of a new gas boiler at about £3,500 including VAT, and our boiler vs heat pump comparison scales that by home size to about £3,200 for two bedrooms. Against that, the whole heat pump job at £3,000 to £7,500 after the grant ranges from £200 less to £4,300 more, plus any radiator work not in the quote. At £176 a year on a heat pump tariff the payback runs from immediate to about 24 years, or about 29 years once VAT returns to electricity, and on a standard tariff there is no payback at all because the heat pump costs £51 a year more to run. The case strengthens when the boiler is due anyway or when the radiators need little work. It does not strengthen because the house is draughty.

Off the gas grid the answer flips. With the £9,000 grant the whole job is £1,500 to £6,000, and the heat pump saves £544 a year against oil on a tariff with oil at 11.3p per kWh, so every £1,000 of extra cost over a new oil boiler pays back in about two years, for as long as oil stays near that price. Claim before 31 March 2027 to get the higher grant. Run your own numbers with our boiler vs heat pump comparison and read heat pump vs new boiler for the fifteen year view.

Ground source is rarely worth considering here. It needs a borehole or a large area of garden for a trench, and under the scheme the middle half of ground source installations in April to June 2026 cost £18,136 to £42,110, well above the air source figures for a house this size. The bungalow's real advantage is its roof: twice the area per square metre of floor that a two storey house has, and possibly a better use of the money.

On a detached bungalow the outdoor unit goes on the side or rear wall nearest the cylinder cupboard. Attached bungalows are tighter than two storey houses. To be permitted development in England, the unit must pass the MCS 020(a) sound calculation, which sets a limit of 37 dB at a point one metre outside the nearest window or door of a habitable room in a neighbouring home, and in a bungalow that window sits at the same height as the unit with no upstairs to lift it clear. The old one metre boundary rule no longer applies. Manufacturers rate units of this size at a sound power from the low 50s to the low 60s dB(A), so most pass, but one forced onto the party wall side may need a quieter model or an acoustic enclosure. Our planning permission guide covers the exceptions.

Controls should be simple. One floor at one temperature needs one thermostat, weather compensation set by the installer and no zone valves to fail. Set it to a comfortable temperature and leave it running: a heat pump is cheapest at a steady low flow temperature and most expensive recovering a cold house twice a day. Ask for quiet mode overnight if the unit sits near a bedroom window, which in a bungalow it often does.

Get three quotes from MCS certified installers and compare them on the design rather than the price. In a two bedroom bungalow the loft depth and the unit size are where quotes diverge most. Each should include:

• A room by room heat loss calculation, with the design outdoor temperature and the loft depth assumed. If you are topping the loft up, make sure it assumes 270 mm.
• The design flow temperature, ideally 50°C or lower, and the seasonal performance expected at it.
• A justification for the unit size if it is well above the calculated heat loss.
• A radiator schedule for all 5 to 7 emitters, which ones change, their new sizes, and whether that work is in the price.
• The cylinder size, whether it is slimline, and exactly which cupboard it goes in.
• An MCS 020(a) sound calculation, if the bungalow is attached or close to a neighbour.
• For oil and LPG bungalows with no mains gas, the £9,000 grant rate and whether tank decommissioning is included.
• The warranties, and confirmation that the installer claims the Boiler Upgrade Scheme and deducts it from the invoice.

Installation is usually quicker than in a two storey house, and longer when several radiators are swapped. Find installers through the MCS installer search. In off-gas areas it is worth including an oil boiler specialist who has added heat pumps alongside a heat pump specialist. Read our old house guide if the bungalow has solid walls or single glazing, and ask for anti-vibration mounts on the wall bracket or plinth.
