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

An air source heat pump for a two bedroom bungalow costs £9,200 to £10,600 installed, the cheapest bungalow job on this site. The £7,500 Boiler Upgrade Scheme grant brings that down to £1,700 to £3,100, and the £9,000 grant for replacing an oil or LPG boiler brings it down to £200 to £1,600. With radiators and a cylinder the whole job is £11,400 to £15,100 before the grant and £3,900 to £7,600 after it. At the Ofgem price cap for October to December 2026, a typical 2-bed bungalow with 8,280 kWh of heat demand costs £514 a year on a heat pump tariff against £733 on gas, but £751 on standard electricity, £18 a year more than the gas boiler it replaces. Two things set this house apart: the unit is smaller, usually 4 to 6 kW, and the loft matters more here than in any other property shape.

Two beds or three: which guide you need

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, with 10,350 kWh of annual heat demand, a 7 to 10 kW unit and £12,000 to £16,000 before the grant. This page is the two bedroom case: roughly 70 square metres, 8,280 kWh, a 4 to 6 kW unit and £11,400 to £15,100 before the grant. On the same insulation level the heat pump itself is about £800 cheaper and the running cost is £128 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.

What a 2-bed bungalow heat pump really costs

Across every house type in England and Wales, the median air source heat pump installation funded by the Boiler Upgrade Scheme cost £12,908 in April to June 2026, with a quarter of jobs under £11,128 and a quarter over £15,627, according to the Microgeneration Certification Scheme (MCS). A two bedroom bungalow sits below the lower quartile. It takes the smallest unit in the bungalow range, has 5 to 7 radiators rather than 8 or 10, needs a modest cylinder and runs every pipe on one level.

Heat demand from the site heat model, built on 39,502 gas heated records in the DESNZ NEED 2026 dataset. Installed cost covers the unit, labour, controls, commissioning and the MCS certificate. Radiators and cylinder are separate, below. With the £9,000 oil and LPG grant, take a further £1,500 off the last column.

Only £1,400 separates the top and bottom rows, and that is the point most quotes miss. Insulation barely moves the price of a small heat pump, because a 5 kW unit and a 7 kW unit sit close together on the price list. What it moves is the flow temperature the system can hold, and therefore the running cost. Most of this guide is about that.

The extremes rarely occur together. A bungalow needing the 6 to 8 kW unit has usually never been insulated, and those houses tend to carry the oversized cast panels of the 1960s and 1970s, which often survive a conversion untouched. Most two bedroom jobs land in the middle: about £13,000 before the grant and £5,500 after it. 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.

How a 2-bed bungalow compares

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 two bedroom home with two storeys.

All at average insulation and the Ofgem cap for October to December 2026, at an effective heat pump tariff rate of 18p. See our 2-bed terrace guide, our 3-bed semi guide and our costs by house type guide for installed prices on each.

A two bedroom bungalow uses 31% more heat than a two bedroom mid terrace and 23% more than a two bedroom semi, and it is more expensive to heat than a 2-bed house of any other shape. 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 houses costs more to run on a heat pump than on gas.

Why one storey costs more to heat

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 come first, and the walls come third. Our insulation calculator ranks the measures for your own property type.

What size heat pump for a 2-bed bungalow

Most two bedroom bungalows end up with a 4 to 6 kW air source heat pump. A well insulated one with 270 mm in the loft, filled cavities and double glazing takes 4 to 5 kW. One with 50 mm of 1970s loft insulation, an unfilled cavity or a conservatory running off the radiators can need 6 to 8 kW. That is one to two size bands below a three bedroom bungalow, and it is the main reason this job is cheaper.

The room by room heat loss calculation decides it, not the bedroom count. Your MCS installer surveys every room and works out its loss on the design day, around minus 3C in the south of England and colder further north. A 70 square metre bungalow with reasonable insulation loses roughly 4 to 5 kW, and the unit covers that plus hot water with a small margin. A quote without that calculation was sized by guesswork.

Oversizing is the specific risk at this size, because 4 and 5 kW models are thin on the ground and installers reach for the 7 kW unit they stock. An oversized heat pump costs more, short cycles on mild days and runs at a lower seasonal efficiency, which shows on every bill for twenty years. If a 7 kW unit is proposed against a 4.5 kW heat loss, ask why in writing.

Loft insulation is the biggest lever here

Nowhere else on this site 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 usually the original 1970s or 1980s depth, and the fix is the cheapest in the retrofit catalogue.

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 £514 down to £396, a saving of £118, and the heat pump also moves from a seasonal efficiency of 2.9 to 3.2 because it can hold a lower flow temperature. The loft is the largest single component of that step in this property type, not the whole of it, and 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 to 100 mm 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, mineral wool lasts 40 years or more, and on a qualifying benefit free loft insulation may be available.

The floor is the second largest surface

The ground floor of a two bedroom bungalow is the same 70 square metres as the loft, and in most pre-1970 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 almost never 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 blasting it twice a day, so draughts through floorboards and cold surfaces at ankle height are far more noticeable. Insulating between the joists and sealing the perimeter gap at the skirting is the difference between a room that feels warm at 20C and one that needs 21C. Underfloor insulation costs £500 to £2,500 depending on access, and a bungalow with a decent crawl space is the easy end of that range.

If the bungalow has a solid concrete floor, which most post 1970 ones do, 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.

Which heat pumps suit a 2-bed bungalow

The 4 to 6 kW class is a smaller market than the 8 to 10 kW class most installers work in every day. Not every brand makes a unit this small, and some will quote the next size up because it is what sits in the van.

Outputs are the nominal ratings in each range that cover a two bedroom bungalow. Grant rates its units at minus 5C air and 55C flow, a harder condition than the 7C most brands quote, so its figures are not directly comparable.

At this size the brands are close and the design decides the result. Ask for a design flow temperature of 50C or lower, a seasonal coefficient of performance (SCOP) above 3.5 in writing, and an MCS 020 noise assessment for the position the unit will actually occupy. R290 units 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.

Radiators, cylinder and pipework

A heat pump heats water to 40 to 50C instead of the 65 to 75C a gas boiler uses, so radiators have to be larger. A two bedroom bungalow has 5 to 7 radiators and 2 to 3 need upsizing, usually the living room, the hall and the main bedroom, at £1,200 to £2,000. Bungalows help here: long, low walls under wide windows mean a double panel radiator in the same slot solves most rooms without moving pipework. Our radiator sizing guide explains how installers choose.

The cylinder is smaller than in the three bedroom case, at 150 to 180 litres, so the space problem is easier. With no landing airing cupboard it goes in the hall cupboard most pre-1980 bungalows still have, the space the old boiler occupied, a utility room or an integral store. A slimline 150 litre cylinder around 450 mm across fits a standard 500 mm deep cupboard. Avoid the loft: a full cylinder weighs over 200 kg and 1960s ceiling joists were not sized for it. On a combi there is no cylinder today, so allow £800 to £1,500 plus somewhere to put it. Our main bungalow guide goes through the cupboard options in more detail.

Pipework is what a bungalow makes cheap. Runs are short and horizontal and nothing drops through a ceiling, so installation is usually two days rather than three. 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.

Running costs: 2-bed bungalow

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. Oil is 9.0p per kWh, the September 2026 kerosene price, and LPG 9.5p. The worked example is a typical two bedroom bungalow with average insulation and 8,280 kWh of heat demand.

8,280 kWh heat demand. Gas at 7.97p/kWh and 90% boiler efficiency. Oil at 9.0p/kWh and LPG at 9.5p/kWh at 85% efficiency. Heat pump COP 2.9 at 26.32p/kWh, or 18p/kWh effective on a well scheduled heat pump tariff such as Octopus Cosy. Standing charges excluded.

On a standard electricity tariff the heat pump costs more to run than the gas boiler it replaces, by £18 a year. That is the honest arithmetic at this price cap, not a rounding error to be argued away: gas rose 9% at the October change while electricity barely moved, and a seasonal efficiency of 2.9 does not close a gap that size between 7.97p gas and 26.32p electricity. 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 18p and the saving becomes £219 a year, or £4,380 over twenty years. 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 £126 a year even on standard electricity and £363 on a heat pump tariff. Against LPG it saves £174 and £411. Against an electric boiler or old storage heaters it is not close: £514 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 the clearest example of it on the site.

Saving is the heat pump on a tariff against a 90% efficient gas boiler. Seasonal efficiency of 3.2, 2.9 and 2.6 for the three rows.

The saving falls as the house gets worse: £227, then £219, then £178. 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 3.2 to 2.6, and the lost efficiency costs more than the extra demand gains. The well insulated bungalow is also the only one of the three that is cheaper to run on standard electricity, at £579 against £623 on gas. Insulating first is not a nice extra before a heat pump in this property type. It decides whether the heat pump has a case at all. Our running costs guide works the same comparison across every house type.

Grants, and the off-gas case

The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump in England and Wales, and since July 2026 £9,000 where it replaces an oil or LPG boiler. On a two bedroom bungalow the second figure almost covers the installation: £9,200 to £10,600 becomes £200 to £1,600. Your MCS certified installer applies and it comes off the invoice. The scheme runs to 2030, installations carry 0% VAT until March 2027, and the bungalow qualifies provided it has a valid EPC and the heat pump covers the whole heating and hot water load. A hybrid keeping the oil boiler as backup does not. Read our BUS grant guide for the detail.

Bungalows are over-represented off the gas grid, in villages and on the edges of towns where the main never arrived. If the bungalow is off gas, has an EPC of D to G and the household income is below £36,000 or someone receives a means tested benefit, the Home Upgrade Grant can fund up to £25,000 of work through the council, including the heat pump, the loft and solar. It is applied for through the council rather than the installer, so check it before accepting a quote. Our grant checker covers the rest.

Is a heat pump worth it for a 2-bed bungalow

On mains gas it is marginal on running cost alone, and mostly a choice about getting off gas. Against a new gas boiler at £2,000 to £3,000, the whole heat pump job costs £1,400 to £5,100 more once radiators and the cylinder are in. At £219 a year on a heat pump tariff that is a payback of roughly 6 to 23 years, and on a standard tariff there is no payback at all because the heat pump costs £18 a year more to run. The case strengthens when the boiler is due anyway, when the radiators need little work, or if you value the 20 to 25 year life against 12 to 15 for a boiler. It does not strengthen because the house is draughty.

Off the gas grid the answer flips. Against a new oil boiler at £3,500 to £5,500, the whole job after the £9,000 grant is £2,400 to £6,100, so the extra outlay ranges from nothing to about £2,600 while the heat pump saves £363 a year on a tariff. That pays back inside eight years at worst and often costs nothing extra on day one. 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 not worth considering here. It needs a borehole or around 200 square metres of trench, costs £20,000 to £30,000, and buys roughly £100 a year more than air source on a house this size. The bungalow's real advantage is its roof: twice the area per square metre of floor that a house has, and a better use of the money.

Placement, noise and controls

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: permitted development in England wants at least one metre from the boundary and MCS 020 wants 42 dB or less at the neighbour's nearest habitable room window, which in a bungalow sits at the same height as the unit with no upstairs to lift it clear. Most units pass at 50 to 55 dB at one metre, but one forced onto the party wall side may need an acoustic enclosure at £300 to £800. 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 20C 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 between 11pm and 7am if the unit sits near a bedroom window, which in a bungalow it often does.

Getting quotes: what to check

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 50C or lower, and the SCOP expected at it.
• A justification for the unit size if it is more than about 1 kW above the calculated heat loss.
• A radiator schedule for all 5 to 7 emitters, which ones change and their new sizes.
• The cylinder size, whether it is slimline, and exactly which cupboard it goes in.
• An MCS 020 noise assessment, if the bungalow is attached or close to a neighbour.
• For oil and LPG bungalows, 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 takes two days for most two bedroom bungalows, three when several radiators are swapped. Find installers through the MCS installer search, and in off-gas areas quote 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. Reduce vibration through a wall bracket or plinth with anti-vibration pads, and track what the system actually uses with an energy monitor.

Frequently asked questions

How much does a heat pump cost for a 2-bed bungalow?

£9,200 to £10,600 installed. After the £7,500 BUS grant you pay £1,700 to £3,100, or £200 to £1,600 with the £9,000 oil and LPG grant. With radiators and a cylinder the whole job is £11,400 to £15,100 before the grant and £3,900 to £7,600 after it.

What size heat pump does a 2-bed bungalow need?

4 to 6 kW for most, 4 to 5 kW when well insulated and 6 to 8 kW when poorly insulated. That is one to two bands below a 3-bed bungalow. Top up the loft before the survey so the installer sizes to the improved house.

How much does a heat pump cost to run in a 2-bed bungalow?

£514 a year on a heat pump tariff or £751 on standard electricity for 8,280 kWh of heat demand, against £733 for gas at the October to December 2026 cap. On a standard tariff the heat pump costs £18 a year more than gas, so the saving depends entirely on the tariff. See our running costs guide.

Why does a 2-bed bungalow use more heat than a 2-bed terrace?

Geometry. A bungalow puts its whole floor area under the loft and on the ground, so it has about twice the roof and floor of a two storey home the same size. A 2-bed bungalow uses 8,280 kWh against 6,300 kWh for a 2-bed mid terrace, despite having the same number of bedrooms.

Is a heat pump worth it for a 2-bed bungalow?

On mains gas it is marginal on running cost alone and mostly a choice about getting off gas: £219 a year on a heat pump tariff, and £18 a year worse than gas on a standard one. Off the gas grid it is clearly worth it, saving £363 a year against oil with the £9,000 grant covering most of the install. Compare with our boiler vs heat pump tool.

Should I insulate the loft before the heat pump survey?

Yes, and in a bungalow more than in any other property. The loft floor is roughly a third of the heat losing envelope. Topping up to 270 mm costs £300 to £600, can drop the unit a size band and cuts running costs by about £118 a year on a heat pump tariff. Done afterwards, you keep the larger heat pump. See our underfloor insulation guide for the second measure.
