WRAS approved bronze circulating pump

Updated: 22 October 2026

Your letting agent asked for WRAS on the invoice, or the cylinder manual says use an approved bronze or stainless circulator, and the amazon.co.uk results only shout bronze body in the title. This page explains Regulation 4, when explicit WRAS wording matters, what the six-row comparison actually states, and how to verify the pump that arrives rather than a sibling model on a trade website. Product specs stay on the [bronze circulating pump comparison](/hub/heating/bronze-circulating-pump). Peter F. compared those amazon.co.uk listings and public UK guidance. There was no lab test. A qualifying purchase can earn a commission at no extra cost to you.

Regulation 4 and WRAS in plain English

The Water Fittings Regulations 1999 require fittings on a potable supply to be of an appropriate quality and fitted so they do not waste or contaminate water. WRAS approval is a familiar UK scheme: manufacturers submit a fitting, and approved items appear on lists installers search. Approval is for the exact model, not a family name or the word bronze. Worcester installation guide 1051705 calls for a WRAS approved bronze or stainless circulator with a non-return valve on a secondary circuit. BPF Pipes Group guidance on continuously operated hot water also points to manufacturer-approved products. None of that replaces the nameplate on the parcel. Store the evidence per model so a later reorder does not drift to a lookalike listing.

When WRAS wording matters most

A homeowner sometimes skips WRAS paperwork if the installer signs off locally. Landlords, HMO agents, schools and care settings usually cannot. The file needs a line from the order to the nameplate. If the job is mechanical and you trust the merchant sheet, a union kit and 130 mm fit can come ahead of WRAS. Those trade-offs are on best bronze circulating pump. When an auditor asks for WRAS, the title and the plate matter more than £10 saved. Stainless ECM recirculation pumps are a different class. Grundfos COMFORT T literature lists drinking-water approvals. A central-heating stainless pump removed from this batch is not a substitute.

What this amazon.co.uk set actually states

This comparison records whether WRAS is stated on each ASIN. Hanicks 97549426 (B0992DD6W7) shows approval in the listing because WRAS approved appears in the amazon.co.uk title, alongside 6 m head, 65 L/min, 1½ inch connections and 5.0 from three reviews. Trident TP256-130BR, GPD25-6SQ-130, Tower BRZPUMP, BritTherm 15-60/130 and Circulation Pump Ltd SE60B do not state WRAS. They must not be written up as WRAS approved without new evidence. Archergas DHW15 is a useful trade reference with a clear WRAS yes on the merchant site, but it is not the Hanicks ASIN. Cross-reference the duty, 6 m, 65 L/min and 130 mm, without mixing up the approval numbers. Merchant copy on Grundfos UPS WRAS products shows the wording pattern auditors recognise, even when that stock is unavailable.

Bronze versus approved stainless

Wilo’s UK FAQ contrasts bronze and stainless for domestic hot water circulation. It focuses on material and hygiene, not on amazon.co.uk models. Approved stainless domestic hot water pumps exist. Bronze remains common on UK cylinder secondary kits because merchants stock 15-60/130 class bodies with familiar unions. Choosing bronze or stainless is a material and approval question. It is not a claim that every bronze listing is WRAS listed. If WRAS is mandatory on the job and Hanicks is out of stock, the next step is a merchant with a searchable approval number, not a cast-iron heating circulator from the wrong category.

Checklist before you sign off

Before the job sheet, keep a screenshot of WRAS wording on the exact ASIN and a nameplate photo that matches the invoice. If the client asks, add the WRAS directory reference for that model. Check seals and non-return valve orientation against the secondary return bronze pump page. Note a timed run where a legionella policy applies. The HSE hot and cold water systems hub is the context. If the title says WRAS and the box label does not, query the seller before you install.

Common questions

Is WRAS legally mandatory for every domestic ensuite loop?
Regulation 4 applies to the suitability of fittings. WRAS is a common way to demonstrate it. Some domestic jobs rely on installer judgement. Regulated portfolios often insist on explicit approval.
How do I verify WRAS on an amazon.co.uk order?
Match the ASIN, the title and the nameplate model. Search the WRAS listings for that model number. Keep the screenshots and the photos in the job file.
Does bronze material automatically satisfy Regulation 4?
No. Material is part of the story. Approval, or other suitable evidence, is still required for clients who want a formal sign-off.
What documents should a landlord keep?
The invoice, a listing screenshot, a nameplate photo, and a WRAS reference if it was requested, plus the install date and who commissioned the loop.
Can I use a stainless ECM pump instead of bronze?
If it is an approved domestic hot water recirculation product sized for your loop, possibly. The fittings and the duty differ. Do not use a central-heating stainless pump from the wrong category.
Does WRAS cover the unions and seals in the kit?
Approval applies to the listed fitting or to the kit scope the manufacturer submitted. Seals and unions supplied separately may need their own approval. Check the certificate scope.
