Paid and Members-Only Energy Market Reports

Energy market reports sit in two very different worlds. One is the commercial research market, where a single title such as BSRIA's World Heat Pump Markets 2026 is a product with a price attached, sold under licence with restrictions on reuse. The other is the trade association and government world, where the same headline numbers are published free to read, often as accredited official statistics or as association news. The figures a householder hears quoted on the news almost always come from the second group.

The most quoted UK solar figure is an official statistic, not a commercial one. Solar PV deployment data covered the UK up to the end of May 2026, and the next release, for December 2026, is confirmed for 28 January 2027 at 9:30am¹. On the European heat pump side, the European Heat Pump Association published market data in August 2026 showing around 2.9 million domestic heat pumps sold across 21 European countries in 2025, with sales growth in 14 of 18 countries analysed³.

What that means for a household is straightforward. The numbers that describe the market are free. What is paid for is the packaging: the forecast, the segmentation, the licence to reproduce a chart, and the analyst time behind it. A home's own energy independence does not depend on any of it, but reading the free layer correctly does, because the paid layer is where the confident projections live.

What a paid or members-only energy market report is

A paid energy market report is a document or dataset sold under a licence. The buyer gets the analysis, and usually the right to read it inside their own organisation, not the right to republish it. That distinction matters more than the price. A chart lifted from a commercial report and posted on a website is a licensing problem, not a citation, and the same applies to a table of figures reproduced in full.

The public sector has its own version of this, and it is instructive because the fees are published. The register of energy performance data charges £12.10 for entering data from which an energy performance certificate and recommendations report may be produced for buildings or building units other than dwellings⁷. A separate fee of £1.70 applies under regulation 25A(b) for entering data from which a non-domestic EPC, a display energy certificate or an inspection report may be produced⁸. These are statutory fees for data handling, not research subscriptions, but they show the principle: some energy data is a priced transaction with a defined purpose.

Members-only data works differently again. A trade association collects sales figures from its members, aggregates them, and publishes the result to the membership first. The value to a member is benchmarking against peers, and the value to the association is that members supply the raw numbers. The public usually sees the headline, not the underlying tables.

For a household, the practical question is what a report can and cannot tell you. It can tell you how many units were sold, in which countries, and at what rate the market is growing. It cannot tell you what a heat pump will cost to run in a particular house, because that depends on the fabric, the emitter sizes and the control strategy. Market data describes a population; a home is a sample of one.

Who publishes the reports householders hear cited

The reports that reach a general audience come from a small set of publishers, and knowing which is which tells you how much weight to give a figure.

Official statistics carry the strongest status. Quarterly Energy Prices is published as accredited official statistics, most recently for December 2025⁹. The Household Energy Efficiency Statistics headline release includes further analysis and geographical breakdowns of ECO measures, ECO delivery costs, estimated carbon and energy savings from measures installed, and the supply chain¹². These are produced under a code of practice, with revisions documented and methods published.

Independent and consumer-facing research forms a second layer. The Energy Consumer Satisfaction Survey is commissioned by Ofgem and Citizens Advice, and covers domestic energy consumers in Great Britain¹⁰. Ofgem also publishes research on consumer attitudes towards the current energy market and price cap¹³. Government-commissioned work sits alongside it: Energy Systems Catapult completed the report on home energy information, advice and guidance¹¹.

The distinction matters because the layers have different incentives. An official statistic is produced to be accurate and is revised when it is wrong. A commercial forecast is produced to be useful to a buyer, and a forecast that turns out badly is quietly superseded rather than corrected in public. When a headline says heat pump sales will reach a certain level by a certain year, the source is almost always the commercial layer, and the number is a projection rather than a measurement.

What reports typically cost, and why many are free to read

Commercial market reports are priced per title or per subscription, and the price is quoted on application rather than published. That is not evasion: the price depends on the number of users, the territories covered and whether the buyer wants the underlying data. A single-seat PDF and an enterprise licence with the dataset behind it are different products.

The free layer is large, and it is free for a reason. Official statistics are published because government needs a common factual base for policy, and because the public has paid for their production. The energy price cap exists in the same spirit: it is a regulatory instrument, and the analysis behind it is published so that it can be challenged. Ofgem's wholesale costs review drew on data collected from 11 suppliers representing 96% of the retail market¹⁴, and its review of historical debt related costs proposed to include costs and revenues across all tariff types, not just customers on variable tariffs¹⁵. Both documents are free to read in full.

Trade association reports are free because members have already paid, through subscriptions, and because the association wants the figures quoted. Solar Heat Europe published its Solar Thermal Market Outlook in September 2026 and made it available free on its website. EHPA publishes its European sales data through its public market data pages.

There is a further category of free data that is easy to overlook: the statutory and regulatory material that defines how the market is measured. The Feed-in Tariff levelisation process apportions cost based on each supplier's share of the Great Britain electricity market, taking into account any FIT contribution already made¹⁶. That is a rule, published in full, and it explains why some suppliers appear in market datasets and others do not.

Membership: what it includes and who qualifies

Trade association membership is a business arrangement, and the benefits are aimed at companies rather than householders. The core of it is data: a member supplies its own sales or installation figures and receives the aggregated market picture in return. That reciprocity is what makes the dataset possible, and it is why the underlying tables are rarely public.

The second benefit is influence. Ofgem's consultation on operating cost allowances set out that it particularly welcomed responses from consumer groups and charities, energy suppliers and industry bodies. Industry bodies are named as a constituency in their own right, which means membership can buy a seat at the table in a way that individual reading of a consultation does not.

The third is access to technical work. BSRIA's role in the heat pump market is a good example of how commercial and grant-funded work sit side by side. The Heat Pump Ready programme lists three projects with public grant values:

• Guru Verify for Heat Pumps, led by Guru Systems Ltd: BEIS grant value £475,162.00¹⁷
• MEASURED, led by Build Test Solutions: £233,887.58¹⁷
• Digitising the Customer Journey of Heat Pumps in Social Housing, led by Switchee Ltd: £468,656.00¹⁷

Those are public grant awards for verification and measurement tools, and the outputs feed into the same evidence base that commercial reports draw on.

For a householder, membership is not the route. The relevant free services are consumer-facing. The Consumer Council NI and Northern Ireland Energy Advice give free, independent and impartial energy advice to all domestic householders in Northern Ireland¹⁸. The Energy Ombudsman service is free of charge to the customer¹⁹, and an independent test of an electricity meter is also free, though the meter accuracy dispute process has its own conditions²⁰.

Where a household wants to understand its own bill rather than the market, the components are published: wholesale costs, network costs, operating, debt and industry costs, EBIT, policy costs, VAT at 5%, the type of energy used, the type of meter installed and how the bill is paid²¹. That is the free layer doing real work.

The flagship reports: heat pump and solar market outlooks

The two reports most often cited in UK coverage are the European heat pump market data and the solar thermal market outlook, and both are free at the headline level.

EHPA's August 2026 market data showed over half of households in Norway, Finland and Sweden owning heat pumps, around 2.9 million domestic heat pumps sold across 21 European countries in 2025, and sales growth in 14 of 18 countries analysed³. The pattern is worth reading carefully: high ownership in the Nordic countries reflects decades of policy and cheap electricity relative to gas, not a recent surge. The 2.9 million figure is a European total, and it says nothing directly about the UK.

Solar Heat Europe published its Solar Thermal Market Outlook in September 2026, free on its website. Solar thermal is the smaller and quieter half of the solar market, and its reports tend to be read by the industry rather than the public.

The UK policy figures that sit behind these reports are published separately. The Warm Homes Plan sets a UK-level ambition to deliver more than 450,000 annual heat pump installations in existing and new buildings by 2030⁴. The government's options assessment for raising minimum standards for heat pumps applies an annual technological progress of 1% to product energy efficiency in the model up to 2035, stable thereafter, and projects that with an annual 1% increase the figure grows to 166.6% SSHEE for standard-temperature air source heat pumps by 2027⁵.

That is a modelled assumption, not a measurement, and it is the kind of figure that travels from a technical annex into a commercial report and then into a headline without the qualifier. The distinction between a target, a model and an outturn is the single most useful thing a reader can carry into any market report.

Independent testing behind the numbers: BSRIA's role

BSRIA occupies an unusual position: it is a commercial testing and research organisation whose output feeds both the paid report market and the public evidence base. Its World Heat Pump Markets 2026 was published in April 2026 as a commercial title.

The testing side is where the numbers originate. A manufacturer's claimed performance is verified against a standard, and the verified figure is what enters a market dataset. That is why a report can quote a coefficient of performance with confidence and why a householder should still treat it as a laboratory figure rather than a prediction for a specific house.

The grant-funded work shows the direction of travel. The three Heat Pump Ready projects listed above, with BEIS grant values of £475,162.00, £233,887.58 and £468,656.00, are all concerned with verification, measurement and the customer journey¹⁷. In other words, the industry is funding work to check whether installed systems perform as specified, which is an admission that the gap between modelled and measured performance is real.

For a household, the practical implication is that a market report tells you what the stock of installations achieves on average, under test conditions or in monitored trials. It does not tell you what a particular installation will achieve. The measured-versus-modelled gap is the subject of its own body of work, and it is the reason a heat pump specification should be based on a room-by-room survey rather than a market average.

How market report data reaches UK government statistics

The path from a manufacturer's sales return to a published government figure runs through several hands, and each hand adds a definition.

1. Trade associations collect member data and publish aggregates.
2. Government analysts combine those aggregates with regulatory returns.
3. Official publications carry the result, with methods and revisions documented.

Ofgem's wholesale costs review, for example, drew on data collected from 11 suppliers representing 96% of the retail market¹⁴, and proposed to exclude one supplier from the analysis sample¹⁴. That is a market report in everything but name, published free as a consultation.

The Feed-in Tariff levelisation process shows the same machinery in a statutory setting: cost is apportioned based on each supplier's share of the Great Britain electricity market, taking into account any FIT contribution already made¹⁶. A supplier's share of the market is therefore not an academic figure; it determines what that supplier pays.

Official publications then carry the result. Energy prices statistics include retail price data and EU comparative data for May 2026². Solar photovoltaics deployment data covers the UK up to the end of May 2026². The Household Energy Efficiency Statistics release includes further analysis and geographical breakdowns of ECO measures, ECO delivery costs, estimated carbon and energy savings from measures installed, and the supply chain¹².

The chain has a weakness worth naming. Where a figure originates in a voluntary member return, it is only as complete as the membership. Where it originates in a regulatory return, it is complete for licensed suppliers but may not capture the whole market. Where it originates in a survey, it carries a sample. A reader who knows which of the three applies can judge how much weight a number will bear.

Where a householder can read the findings without paying

Almost everything a household needs is free, and the free versions are usually better sourced than the paid ones.

Start with the official statistics. Solar PV deployment is published as accredited official statistics, with the April 2021 release published on 27 May 2021 as an example of the series²³. The next release, for December 2026, is confirmed for 28 January 2027 at 9:30am¹. Quarterly Energy Prices is published as accredited official statistics⁹, and the June 2024 edition is described as a quarterly statistical publication on energy prices²⁴. Older editions exist for comparison: the June 2016 edition is also a quarterly statistical publication²⁵, and Energy Trends has published Major Power Producers data monthly²⁶.

For European context, the association pages are the free route. EHPA's market data pages carry the sales figures³, and Solar Heat Europe's outlook is free on its website.

For advice rather than data, the devolved picture differs. The Consumer Council NI and Northern Ireland Energy Advice give free, independent and impartial energy advice to all domestic householders in Northern Ireland¹⁸. In Northern Ireland, energy prices were not capped and suppliers have the flexibility to set their tariffs independently to reflect their costs of operating²⁷, which means the market data for the province is not directly comparable with Great Britain. Low carbon heating guidance for Northern Ireland is published separately²⁸.

The wider point for a household's energy independence is that the data describing the market is a public good, and the paid layer is a convenience. A home that wants to know how many heat pumps were installed in its area, what solar capacity exists, or how prices have moved can find all of it free. What it cannot find free is a prediction, and a prediction is the one thing a household does not need.
