What heat pumps work involves
An air source heat pump replaces a boiler with a unit outside the property that moves heat into your heating system at a lower flow temperature. Because the flow temperature is lower, the emitters and the cylinder matter as much as the heat pump itself.
Air source heat pump costs depend on heat loss, radiator upgrades and cylinder work.
Estimated cost
Most heat pumps projects we hold cost data for fall between £8,000 and £12,000. Air-source, 8kW
The estimator for this service isn't available yet.
Estimated range only. The actual price depends on site-specific factors such as access, condition and specification.
What changes the price
- Heat loss of the property
- The design starts with a room-by-room heat loss calculation, which sets the size of everything else.
- Radiator or underfloor changes
- Lower flow temperatures often mean some emitters need to be larger.
- Hot water cylinder
- A suitably sized cylinder with a large coil is normally required.
- Outdoor unit position and pipework
- Distance from the plant position to the heating system affects pipe runs and groundwork.
- Electrical supply
- A dedicated circuit is needed, and the consumer unit sometimes needs work.
- Insulation and airtightness
- A poorly insulated property needs a larger unit and runs less efficiently.
Heat pumps in Hastings
Hastings addresses in our coverage data start with the TN34 postcode.
It sits within East Sussex.

What a contractor will ask about your property
- What heats the property now, and how old is the system?
- What type and size are the existing radiators?
- Is there loft and wall insulation?
- Where could the outdoor unit stand?
- Is there space for a hot water cylinder?
- What heats your home today?
- How many bedrooms?
- What insulation do you have?
- Are you interested in the government grant?

Permissions and regulations
- Many domestic air source installations are permitted development subject to size and siting conditions; listed buildings and conservation areas differ.
- Building regulations apply to the heating system, hot water and electrical work.
- Grant schemes have their own eligibility and installer requirements.
Problems that commonly come up
- Undersized emitters that leave rooms cool at a sensible flow temperature.
- No practical position for the outdoor unit within noise and siting limits.
- No space for a cylinder in a property previously run on a combi boiler.
- Microbore pipework that restricts flow.
When you need a specialist
- Underfloor heating and significant emitter replacement may bring in additional trades.
- Where the electrical supply is marginal, an electrician should assess it before design is finalised.

Common questions
Will a heat pump work in an older house?
It can, but the design has to reflect the actual heat loss. Insulation improvements and larger emitters are often part of the project.
Do I have to replace all my radiators?
Rarely all of them. The heat loss calculation identifies which rooms need a larger emitter at the design flow temperature.
Are grants available?
Government schemes exist and change over time. Eligibility depends on the property and the installer, so check the current scheme rules rather than relying on an estimate.
Is the estimate a quotation?
No. Heat pump pricing depends on a heat loss survey; the estimator gives an indicative range only.
