Best Fuse Board Brands UK 2026 — Hager, Schneider, Lewden, Crabtree

BS 7671:2018 Amendment 4 was published April 2026 and applies to new electrical work from October 2026. The single biggest practical change is Type A RCD protection where DC fault current is foreseeable — which now covers most modern domestic boards.

AFDDs are mandatory on socket circuits in higher-risk premises (HMOs, residential care, schools). For domestic, AFDDs are recommended but not yet required. Boards should be specified with optional AFDD-capable slots.

SPD (surge protection device) is now expected on the main intake. Type 2 SPD is sufficient for most London homes. Adds £80–£120 to a fuse board upgrade but reduces transient damage from grid spikes — common with overhead line areas.

All four brands below offer A4:2026-compliant ranges as of mid-2026. The question is execution: terminal quality, RCBO availability, and how the board feels at second-fix.

Hager's Design 50 range dominates UK domestic installs in 2026. Solid plastic clip retention, generous busbar, and the most reliable Type A RCBOs at this price point.

Strengths: RCBOs ship with reliable test buttons, busbar is captive, terminations stay tight. Schemes consistently grade Hager installs well at audit.

Weaknesses: surface-mounted variants are bulkier than competitors. Premium pricing (board + 12 RCBOs £280-340 trade, before labour).

Best for: standard residential installs, MEES-prep upgrades, landlord-portfolio repeat work. Our go-to for 70%+ of domestic upgrades.

Schneider's Easy9 (residential) and Acti9 (commercial) ranges are universal. Acti9 dominates UK commercial installs and Easy9 is a credible residential challenger.

Strengths: Acti9 modular RCBOs are easily the best in class for commercial. Replacement parts widely available. Type A RCBOs ship in volume.

Weaknesses: Easy9 residential boards have plastic terminations that loosen over time more than Hager. Less forgiving of poor first-fix.

Best for: commercial three-phase boards, large residential (5+ bed houses), and any install where future expansion is likely.

Lewden has emerged as the strongest value brand. Type A metal-clad consumer units at £140-180 trade. RCBOs at £18-24 each. Total board (12 RCBOs) trade cost around £210.

Strengths: surprisingly solid terminations for the price. Genuinely A4:2026-compliant Type A RCBOs. Lewden Pro range is competitive with Hager at 30% less cost.

Weaknesses: smaller distribution network — sometimes parts take longer to source if you need a specific RCBO mid-week. Less brand recognition with picky customers.

Best for: cost-sensitive landlord upgrades, MEES-mandated upgrades where the customer is doing a portfolio at once, and second properties.

Crabtree (now Eaton-owned) and Wylex were the dominant UK domestic brands of the 1990s and early 2000s. Modern Crabtree Starbreaker and Wylex NHRS ranges are competitive but not market-leading.

Strengths: spare parts widely available for legacy boards. Repair-don't-replace economics work for Wylex up to about 15 years of age.

Weaknesses: build quality is good but not exceptional. RCBO availability is fine but not as instant as Hager. Pricing is mid-range without the value of Lewden.

Best for: like-for-like replacements where a homeowner wants to keep the brand. For new specs, we'd choose Hager or Lewden.

1. Hager — best overall, best build quality, best installer experience.

2. Lewden — best value, A4:2026-compliant at 30% less than Hager.

3. Schneider — best for commercial and large residential.

4. Crabtree/Wylex — fine for legacy repairs, not first choice for new installs.

Whichever brand: insist on Type A RCBOs (not Type AC), Type 2 SPD on the main intake, and ample spare ways for future EV/heat pump circuits. Future-proofing a board today saves a full re-install in 2029-2030.
