LRQA, which runs NERS for the DNOs, does not publish a fee for NERS accreditation. The trade bodies that do publish fees charge a firm of 10 to 249 staff anything from under a thousand pounds to over ten thousand a year, depending on the body and the firm's turnover. On 1 October 2026, none of nine trade body and prequalification directories appeared in 168 search results for eighteen buyer questions. The NERS register appeared twice, and both times it ranked first.
Assistants tend to treat a claim as settled when somebody other than the firm makes it, and registers and trade bodies are the obvious somebody. Below: what each costs, who it suits, and how often it turned up where buyers look.
What does NERS accreditation cost?
LRQA does not publish a fee on its NERS pages. The only estimate we found was in a management systems consultancy's guide from 2022, not from LRQA, and we do not repeat it here as a price. If you need a number, ask LRQA for a quote against the scopes and voltages you want approval for.
What LRQA does publish is the register, the strongest third-party record in the sector: public, 538 providers on 1 October, every scope of approval by voltage and a named contact on each entry. NERS is recognised by every mainland DNO and required for contestable connection work.
How this was checked
Every fee below was read on the institution's own live pages on 1 October 2026, or in a fee document those pages link to. Where a body does not publish a fee, the table says “not published”. Whether VAT is included is stated only where the source says so.
The same day we ran eighteen buyer questions across four markets and recorded all 168 results by kind of source, which is how we know which of these institutions a buyer meets. The samples are written up in which ICPs does AI recommend, who gets named for a UPS maintenance contract and who writes the BESS lists; the power equipment set is on power equipment marketing.
What this does not show
- Prices that will hold. Fees are as published on 1 October 2026 and change, some on 1 January.
- That a fee does not exist. “Not published” means we did not find it on the institution's own pages that day.
- What any assistant said. The 168 results are search results, the material assistants draw on, sampled once through a search tool that runs from the United States rather than Google UK. Twelve of the eighteen questions returned nine results rather than ten.
- That a membership is worth having or not. Most are bought for reasons that have nothing to do with search: compliance, procurement, technical standing, the network.

Two quirks, reported as printed. The AMPS page starts its £5m band at £4,999,999, which looks like a typo. The Solar Energy UK fee document leaves a gap between £24m and £25m.
Did any of them appear in search results?
Almost never. Across 168 results for eighteen buyer questions on 1 October, none of the nine trade body and prequalification directories appeared: not ECA, BEAMA, AMPS, REA, Solar Energy UK, Achilles UVDB, Constructionline, CHAS or SafeContractor. Five of them run public, searchable member directories, and still none turned up.
The NERS register appeared twice. Both times it ranked first, on the two ICP questions that used the scheme's own wording: “NERS accredited ICP list” and “ICP for 11kV connection”. On the three ICP questions phrased without that vocabulary, it was absent.
Two other industry bodies did appear: the network operators' industry body, with a guide from 2020, and a renewables trade body with a policy blog. Neither names a supplier. Ofgem and a DNO appeared on the question about using someone other than the DNO, and they name no firm either.
What did name firms from the outside was trade press, a market-data firm's list and listicles: 22 of 46 results in battery storage, one in critical power.
Public directories and closed schemes
These institutions split into two groups, and the split matters more than the fee. NERS, ECA, BEAMA, AMPS, REA and Solar Energy UK publish directories anyone can search, so an assistant can in principle read them and a buyer can be sent to them.
Achilles UVDB, Constructionline, CHAS and SafeContractor are prequalification schemes, bought to pass procurement rather than to be found. Their databases are closed, so an assistant cannot read them, and their only public trace is what the firm says about itself.
A framework you cannot bid without is worth its fee whatever a search engine thinks. Just do not expect a CHAS or UVDB badge on a website to work as independent evidence.
What a membership buys, and what it does not
A membership buys a directory listing that assistants rarely surface on their own. The value comes from getting the membership mentioned where answers already draw from, and three of those places are within a firm's reach:
- Your own pages, with the membership or accreditation stated, the certificate or member number printed, and the register or directory entry linked. None of the five ICPs we checked did this.
- The trade press, through real projects. Trade press carried six of the 46 storage results, and in switchgear the only trade press present was writing about a multinational.
- The register entry itself, kept complete and current, with your scopes, regions and a named contact, because it is the one record that ranks first when a buyer uses the scheme's vocabulary.
Which to start with
By type of firm, on this evidence:
- An ICP: NERS is required anyway. Link the register entry from every ICP page and print your scopes by voltage.
- A generator, UPS or critical power service firm: AMPS, at £1,815 for a firm turning over £1m to £5m, plus trade press on real maintenance work.
- A manufacturer of electrotechnical equipment: BEAMA, whose fee is not published, so ask.
- An electrical or HV contractor: ECA, whose contractor fee is on enquiry and whose directory filters by High Voltage.
- A storage or solar EPC or O&M firm: REA or Solar Energy UK, both with directories that filter by activity, plus the market lists and trade press that already shape that market.
- Anyone bidding into utilities or construction: the prequalification scheme your buyers require, bought for the bid and not for visibility.
The work of making these memberships count is the corroboration workstream in the Pipeline Engine. Sector detail is on power equipment and critical power and grid and storage delivery. It starts with the Pipeline Diagnostic, which lists the sources behind every answer your buyers get.
Quick answers
- How much does NERS accreditation cost?
- LRQA, which runs the scheme for the DNOs, does not publish a fee. The only estimate we found was in a consultancy's 2022 guide, not from LRQA, so we do not repeat it as a price. Ask LRQA for a quote against the scopes and voltages you want approval for.
- Is the NERS register public?
- Yes. It needs no login and on 1 October 2026 listed 538 providers, filterable by region, by voltage and scope and by site type, with every scope of approval and a named contact on each entry. It ranks nobody. In our samples that day it ranked first whenever the buyer used the scheme's own wording.
- How much is AMPS membership?
- AMPS publishes annual fees by turnover, excluding VAT: £825 under £250k, £1,815 for £1m to £5m, £2,118 for £5m to £20m and £2,420 for £20m to £50m, rising to £3,630 at the top. Membership renews on 1 January and needs at least twelve months of trading.
- Do trade body directories help a firm appear in AI answers?
- Not by themselves, on our evidence. None of nine trade body and prequalification directories appeared in 168 search results for eighteen buyer questions on 1 October 2026. A listing helps when something an assistant reads points to it: the firm's own page with the membership stated and linked, or a trade article.
- Can a DNO recommend an ICP?
- There is no route for a supplier to be listed or recommended by a DNO. DNO connection pages tell customers they may use an ICP or IDNO for contestable work. The one we checked on 1 October 2026 points to its own alternative-providers page rather than naming firms.
