Heat Pump Prices in Bristol
Here are the price bands we see most often for Bristol installations, with the grant shown separately. They’re realistic ranges rather than “from” figures, and they include fitting.
| Installation | Price range (fitted) | What’s involved |
|---|---|---|
| One room, air-to-air | £1,500 – £3,500 | A single wall-mounted indoor unit paired with its own outdoor unit. |
| Two rooms on one outdoor unit | £3,000 – £6,000 | A multi-split serving, say, the front room and the main bedroom. |
| Four or more rooms | £5,000 – £12,000+ | Most of a flat or house, with more pipework and several indoor heads. |
| Air-to-water heat pump (boiler swap) | £8,000 – £14,000 | Runs radiators and a hot water cylinder. Shown before grant; big houses can exceed this. |
Ranges reflect typical Bristol installs in 2026. We confirm an exact figure in writing after visiting the property. Where the property qualifies, the Boiler Upgrade Scheme knocks £2,500 off air-to-air or £7,500 off air-to-water. The installer claims it, so it comes straight off your bill.
The Things That Move the Price
- How many indoor heads — every extra room means another unit, more pipe and more hours.
- How much heat each room loses — solid walls, big sash windows and tall ceilings need a bigger unit.
- Distance between the units — a long route up a three-storey terrace costs more than a back-to-back install.
- Your fuse board — a new radial circuit is usually needed, and older boards sometimes need upgrading.
- The equipment chosen — whisper-quiet and top-efficiency models carry a premium.
- Reaching the wall — scaffold towers or a platform for high or awkward elevations.
- Finishing — pipe covers, drain runs and a tidy-up of plaster and paint.
- Whether the grant applies — a qualifying job has £2,500 or £7,500 deducted.
Bristol Examples
Ground-floor flat in Redland, storage heaters
Two indoor units (lounge-kitchen and bedroom) on one multi-split outdoor unit in the rear garden, with the freeholder’s written consent. Short pipe runs, one new circuit. Storage heaters removed. Typically in the lower half of the two-room band, with a strong case for the £2,500 grant.
Loft bedroom in a Bishopston terrace
A dormer room that roasts in July and is chilly in January. One floor console under the dormer window, with the pipe run down the rear elevation to a bracket above the kitchen extension roof. Middle of the one-room band, given the height and the extra pipe.
Three-bed semi in Westbury-on-Trym, gas boiler
Owners wanted cheaper heating in the rooms they live in and cooling for hot nights. Three indoor units on a multi-split, boiler kept for hot water and occasional use. Upper end of the multi-room band; not eligible for the grant because the gas system stays.
Victorian semi in Knowle, full boiler swap
Air-to-water heat pump with a new cylinder in the old airing cupboard and four larger radiators. Middle of the air-to-water band before the £7,500 grant.

What’s Included
- Survey, heat-loss calculation and system design;
- all indoor and outdoor units, brackets or bases and anti-vibration feet;
- refrigerant pipework, insulation, trunking and condensate drains;
- a dedicated electrical circuit and isolator;
- pressure testing, evacuation and commissioning;
- removal of packaging, and of old heaters where agreed;
- warranty registration and a handover of the controls.
Possible extras — a consumer unit upgrade, scaffolding for a high wall, or decorating after a pipe route — are listed separately so nothing appears later as a surprise.
Comparing Quotes
When you line up prices from different installers, check:
- whether each room has been sized from a heat-loss figure or just floor area;
- the exact make, model and output of every unit;
- the planned outdoor position and pipe route;
- whether electrics, drains and trunking are included;
- who handles the grant, and whether the quote shows both pre- and post-grant totals;
- warranty length and what servicing is required to keep it.
Equipment Choices and Price
Within each price band, the equipment makes a difference. Entry-level units do the job well for most rooms. Premium models add quieter operation, higher seasonal efficiency, better filtration, slimmer designs and more capable apps. For a bedroom where noise matters, or a room you heat every day, the extra efficiency and comfort can be worth it. We’ll usually show two options on the proposal so you can compare.
Running Costs
Electric heaters give one unit of heat per unit of electricity. A well-installed air-to-air system typically gives two and a half to four. On the same tariff, that’s roughly a third to a half of the running cost for the same warmth. Against mains gas the saving is slimmer and shifts with prices, yet warming only occupied rooms and getting cooling thrown in usually tips the balance.
Keeping Costs Down
- Start with the rooms you use most and add others later.
- Keep units close together where possible — shorter pipe runs cost less.
- Sort cheap insulation and draught-proofing first; it can mean a smaller unit.
- Check grant eligibility early, as it can change which option is cheapest overall.
Air-to-Water Costs
Swapping a boiler is a bigger job: as well as the outdoor unit there’s a cylinder, new controls, pipe alterations and often a few bigger radiators. Most Bristol houses come in at £8,000–£14,000 fitted, pre-grant; big or complicated homes can go higher. Eligible installations have £7,500 deducted, or £9,000 where oil or LPG is being replaced with no mains gas until March 2027. More on the boiler replacement page.
Servicing Costs
An annual service typically costs £70 to £250 per system depending on the number of units and what’s involved. Regular servicing is usually a warranty condition. See maintenance and repairs.
