Heat Pump Guide UK Editorial Policy

Our Editorial Principles

Heat Pump Guide UK exists to make complicated heating technology easier to research, understand and compare.

Whether we are writing about a domestic heat pump, commercial manufacturer, refrigerant, heating control or industrial system, our editorial approach is based on the same principles.

• Accuracy before speed: we would rather qualify a claim or identify uncertainty than present an unsupported figure as fact.
• Evidence before marketing: manufacturer claims can be useful sources of technical information, but promotional claims are not automatically treated as independent evidence.
• UK relevance: we prioritise information relevant to UK buildings, regulations, energy markets, products and support schemes.
• Context matters: headline efficiency figures, temperatures and specifications are explained alongside the conditions that affect real-world performance.
• Clear commercial boundaries: payment or a commercial relationship cannot purchase a favourable independent conclusion.
• Transparency: material commercial involvement should be made clear to readers.
• Corrections matter: material errors should be corrected when they are identified.

Who Is Responsible for Our Content?

David Tooth is the founder and primary researcher behind Heat Pump Guide UK and is responsible for the site’s overall editorial direction.

David researches residential, commercial and emerging heat-pump technology using published evidence, technical documentation and relevant specialist sources.

David is not a heating engineer and Heat Pump Guide UK does not provide project-specific engineering design, heat-loss calculations or system specifications. Where a subject requires specialist engineering judgement, our role is to explain the available evidence and considerations rather than replace appropriately qualified professional advice.

You can learn more about David, Heat Pump Guide UK’s background and the purpose of the site on our About page.

How We Research Heat Pump Topics

The sources used vary according to the subject, but we aim to use primary and authoritative information wherever practical.

Sources may include:

• UK government departments and official schemes
• Ofgem publications and energy-market information
• Energy Saving Trust and Carbon Trust resources
• Relevant industry and building-services guidance
• Manufacturer datasheets, installation manuals and technical documentation
• Published product specifications and performance information
• Relevant legislation, regulations, standards and official guidance
• Academic or technical research where appropriate
• Real project data and case studies
• Expert commentary from engineers, manufacturers, researchers and industry specialists

We do not assume that every source has equal evidential value. A measured result from an operating system, for example, is different from a theoretical calculation, manufacturer specification or marketing claim.

Where those distinctions materially affect the conclusion, we aim to make them clear.

Prices, Costs and Savings

Prices, tariffs, grants, equipment costs and installation costs can change.

When we publish cost information, our aim is to explain both the available figures and the factors that can cause actual costs to differ.

Where an article contains an example calculation, estimate or indicative price range, it should not be interpreted as a quotation or guarantee.

Heat-pump running costs and potential savings can vary significantly according to:

• Heat demand
• System efficiency
• Flow temperature
• Electricity and alternative-fuel prices
• Heating patterns and occupancy
• Controls and commissioning
• Hot-water requirements
• Building fabric and heat loss

We therefore avoid presenting savings as guaranteed outcomes.

Product Comparisons and Recommendations

Some Heat Pump Guide UK articles compare heat pumps, controls, thermostats, accessories and other relevant products.

There is rarely one product that is objectively best for every property or application. Where we use terms such as “best”, our intention is to identify options that perform strongly against relevant criteria and to explain the circumstances in which different products may be better suited.

Depending on the category, comparison criteria may include:

• Published performance and efficiency
• Operating temperature range
• Output and system suitability
• Controls and usability
• Noise
• Refrigerant
• Warranty information
• Product range and available configurations
• UK availability and support
• Relevant features and limitations
• Price or overall value where reliable pricing is available

Not every factor applies to every comparison.

Manufacturers and commercial partners cannot purchase a position within an independent ranking, a guaranteed recommendation or a favourable conclusion.

Manufacturer Information

Manufacturers are often the primary source for product specifications, operating limits, dimensions, refrigerants, warranties and other technical information.

We therefore use manufacturer documentation where it is the most appropriate source, but distinguish between technical specifications and promotional claims.

Where a claim is particularly important to an article’s conclusion, we may seek supporting technical information or compare it with other available sources before presenting it as established fact.

The fact that a manufacturer supplies information to Heat Pump Guide UK does not guarantee that the company or product will be included in an article.

Expert Contributions

Heat Pump Guide UK welcomes useful technical input from people with relevant first-hand expertise.

This may include engineers, manufacturers, installers, researchers, consultants, building-services professionals, technology specialists and people involved in real heat-pump projects.

Expert input may take the form of:

• Technical explanations
• Answers to specific editorial questions
• Commentary on developing technologies
• Project information and case studies
• Measured performance data
• Product documentation
• Practical lessons from design, installation or operation

Where appropriate, contributors may be identified by name, role and organisation so readers can understand the source of the information.

An expert contribution does not automatically imply endorsement of the contributor, their employer, products or services.

Commercial Partnerships and Sponsored Content

Heat Pump Guide UK may enter into paid commercial relationships with relevant manufacturers, technology companies, suppliers, agencies and other organisations.

Commercial partnerships help fund the continued development of the site and can also provide access to specialist expertise, technical information, products, projects and data that may be useful to our readers.

However, commercial participation and independent editorial judgement are separate.

Payment does not entitle a partner to:

• A guaranteed positive conclusion
• A higher position in an independent product or manufacturer ranking
• Guaranteed inclusion in unrelated editorial guides
• Removal of legitimate limitations or criticism
• Control over Heat Pump Guide UK’s wider editorial coverage

Where a company has paid for or materially sponsored a particular piece of content, that relationship should be disclosed clearly enough for readers to understand the nature of the content.

Organisations interested in editorial contributions or commercial partnerships can find more information on our Work With Heat Pump Guide UK page.

Sponsored Links

Where an outbound link exists because of a paid commercial relationship, Heat Pump Guide UK applies appropriate link attributes rather than presenting it as an independent editorial endorsement.

Commercial arrangements do not provide a right to manipulate search rankings through undisclosed paid links.

Affiliate Links

Some Heat Pump Guide UK content may contain affiliate links. If a reader clicks an eligible affiliate link and subsequently makes a purchase, Heat Pump Guide UK may receive a commission without increasing the price paid by the reader.

Where affiliate content requires a disclosure, we aim to make that commercial relationship clear to readers.

Affiliate availability does not determine whether a product is eligible for consideration and does not guarantee a favourable recommendation.

Where practical, our product comparisons consider suitability and evidence first rather than commission potential.

Products Supplied for Review or Research

A manufacturer or supplier may occasionally provide access to a product, demonstration, software platform, technical briefing or other resource for research purposes.

Receiving access to a product or service does not guarantee positive coverage.

Where free access, a sample, loan or other material relationship is relevant to understanding a review or recommendation, we aim to disclose it appropriately.

We will not describe a product as independently tested by Heat Pump Guide UK unless meaningful testing has actually taken place.

Case Studies and Project Data

Real-world projects can provide valuable evidence, particularly within commercial and industrial heat-pump research.

When assessing case studies, we are particularly interested in information such as:

• Building or application type
• Previous heating arrangement
• System capacity and configuration
• Operating and design temperatures
• Refrigerant
• Heat source and heat sink
• Measured energy consumption
• Measured efficiency or performance data
• Commissioning information
• Project challenges and lessons

We aim to distinguish measured results from modelled savings, manufacturer projections and estimated outcomes.

AI-Assisted Research and Content Production

Heat Pump Guide UK may use artificial-intelligence tools to assist parts of the research and editorial workflow.

AI tools can be useful for organising research, comparing information, identifying questions that require further investigation, analysing datasets and assisting with drafting or editing.

AI-generated output is not treated as an authoritative source of factual information.

Material factual claims should be supported by appropriate sources, and editorial responsibility for content published on Heat Pump Guide UK remains with the site rather than an AI system.

We do not knowingly use AI as a substitute for verification where current prices, regulations, grants, specifications, safety information or other material facts require checking against reliable sources.

Updates and Content Reviews

Heat-pump technology and the UK energy market change regularly. Manufacturers update product ranges, electricity prices move, government schemes change and new technical evidence becomes available.

Important pages are therefore reviewed and updated where appropriate.

An updated date does not necessarily mean that every sentence on a page changed on that date. It indicates that the content has been reviewed or materially revised.

Areas particularly likely to require ongoing review include:

• Energy prices and tariffs
• Government grants and eligibility rules
• Product ranges and specifications
• Installation costs
• Regulations and official guidance
• Commercial heat-pump technology
• New refrigerants and product developments

Corrections

Despite our efforts to check information before publication, errors can occur.

If we identify a material factual error, our policy is to correct the article rather than leave information online that we know to be inaccurate.

Minor spelling, formatting or clarity changes may be made without a specific correction notice.

Where a correction materially changes the meaning of an article or an important conclusion, we may add clarification within the page where appropriate.

If you believe information published on Heat Pump Guide UK is incorrect, you can contact us with the relevant page, claim and supporting evidence.

Conflicts of Interest

A commercial, affiliate or professional relationship can be relevant to how a reader interprets content.

Where such a relationship is material to a specific article, recommendation or conclusion, our aim is to disclose it appropriately rather than leave readers unaware of it.

Heat Pump Guide UK does not accept payment in exchange for presenting paid opinion as independent editorial judgement.
