Start With What You Want to Improve

You do not necessarily need to start by replacing your heating system. Choose the route that best matches what you are trying to achieve at home.

Improve My Existing Heating

If your boiler still works, start with controls, radiator performance and smaller upgrades that could reduce wasted heating now.

Move to a Heat Pump

Compare air source heat pumps, installation costs, radiators, running costs and the practical questions to check before switching.

How Our Heat Pump Advice Is Researched

Heat Pump Guide UK is written primarily to help UK homeowners make better heating decisions before committing to expensive upgrades.

Our guides cover heat pumps, running costs, grants, radiators, flow temperatures, smart heating controls and home air conditioning. We use official scheme information, independent energy guidance and public technical information where relevant.

We are not a heat pump installer and we do not sell installations. The aim is to help you understand the options, compare claims more carefully and ask better questions before spending money.

Choose the Right Path for Your Home

Whether you are trying to lower bills, replace a boiler, improve comfort or add summer cooling, start with the problem you actually want to solve.

My Boiler Still Works

See whether better controls, heating schedules and room-by-room control should come before a full heating-system replacement.

Heat Pump vs Smart Controls →

I Want a Heat Pump

Compare the main air source heat pump options and the practical differences that matter in UK homes.

Best Air Source Heat Pumps →

I Want to Replace My Current Heating

Switching from gas, oil or LPG can involve different costs, hot-water changes and running-cost considerations.

I Want to Understand the Cost

See installation costs, grants, common extras and why two heat-pump quotes can look very different.

I Am Not Sure My Home Is Suitable

Start with heat loss, radiator output and flow temperature rather than assuming your home is either suitable or unsuitable from its age alone.

Check Radiator Requirements →

I Want Summer Cooling Too

Air conditioning can be a separate homeowner route. Many fixed systems can cool in summer and operate as air-to-air heat pumps for heating.

Home Air Conditioning Guide →

Before You Replace a Working Boiler

If the main problem is high bills, uneven temperatures or heating being left on longer than necessary, a complete heating-system replacement may not be the first thing worth doing.

Smart thermostats for UK heating controls

Smart Thermostats

Improve schedules, control and visibility if your current heating is running longer than necessary.

Smart TRVs

Useful where bedrooms, offices or other rooms need different temperatures or are used at different times.

Heating Upgrades

Compare controls, radiator balancing, emitter upgrades and insulation before replacing a boiler that still works.

See the Upgrade Guide →

Want Summer Cooling as Well as Heating?

Heat pumps do not all deliver heat in the same way. A conventional UK air-to-water system heats water for radiators or underfloor heating, while fixed air-conditioning systems can use an air-to-air heat-pump cycle to provide both cooling and warm air.

If summer comfort matters as much as winter heating, this is a separate route worth understanding before you choose a system.

Home Air Conditioning

Understand portable, fixed split and multi-split air conditioning, whole-home options, installation, noise and cooling considerations.

Best Portable AC Units →

Air-to-Air Heat Pumps

Learn how reversible fixed air-conditioning systems can provide heating as well as cooling and where they differ from radiator-based heat pumps.

Air-to-Air Heat Pumps →

Heat Pump or Air Conditioning?

Compare air-to-water central heating with heating-and-cooling air conditioning if you are unsure which route suits your home.

Compare the Two →

Two different homeowner journeys

If you mainly want whole-home wet central heating and hot water, conventional air-to-water heat pumps remain the natural starting point. If cooling is a priority, explore air conditioning and air-to-air systems before deciding.

What Matters Most When Choosing a Heat Pump?

A heat pump should be judged as part of a complete heating system rather than by the outdoor unit alone.

The Heat Pump

Compare output, noise, efficiency, controls, support and suitability rather than choosing from brand recognition alone.

Compare Heat Pumps →

Heat Loss & Radiators

The home needs enough emitter output at sensible flow temperatures if the heat pump is to work efficiently.

Radiators & Heat Pumps →

Installation & Running Costs

Look at the full project cost and expected annual operation rather than comparing the equipment price in isolation.

Controls & Temperature

Weather compensation, sensible flow temperatures and appropriate controls can materially affect comfort and electricity use.

Common Heat Pump Questions

If you are still deciding whether a heat pump is right for your home, these are some of the most useful questions to investigate first.

Are Heat Pumps Worth It?

Compare the benefits, drawbacks, costs and practical considerations before deciding whether to switch.

See the Pros & Cons →

Do Heat Pumps Work in Winter?

Understand cold-weather operation, output, defrost and what matters more than the minimum temperature on a brochure.

Winter Performance →

Do I Need New Radiators?

Find out why radiator output changes at lower temperatures and why some rooms may need upgrades while others do not.

Check Your Radiators →

Do I Need a High-Temperature Heat Pump?

See when 65°C+ capability can help with an existing heating system and why the lowest practical flow temperature still matters.

High-Temperature Heat Pumps →

Why Is My Heat Pump Not Saving Money?

High flow temperatures, controls, tariffs, emitters and commissioning can all affect the result.

Troubleshoot Running Costs →

Why Are My Energy Bills So High?

Check schedules, unused rooms, insulation, hot water and other causes before assuming the heating appliance itself is the problem.

Find the Cause →

Why Trust Heat Pump Guide UK?

Independent, UK-focused advice designed to help homeowners understand heating, heat pumps and home cooling before making expensive decisions.

Independent by Design

We are not a heat pump installer, so our guides are written to explain the decision rather than push you towards an installation company.

Built Around UK Homes

Our content focuses on the questions UK homeowners actually face: costs, grants, radiators, controls, tariffs, older homes and practical system design.

Focused on the Complete System

Heat loss, emitters, flow temperature, controls and installation quality can be just as important as the heat pump itself.

Clear About Limitations

No guide can guarantee your savings or performance. Results depend on the property, system design, installation, usage and energy tariff.

Researching Heat Pumps for a Business or Commercial Building?

Heat Pump Guide UK is primarily a homeowner resource, but we also publish independent guidance for businesses, estates teams and organisations researching larger non-domestic heat-pump systems.

The commercial section covers system types, air source heat pumps, costs, design and procurement, manufacturer selection and the distinction between commercial building heating and industrial process heat.
