How we research products, choose picks, and check our sources.
Daily Tech Navigator is an anonymous editorial team publishing buying guides for smart home, home energy (Octopus Agile, portable power stations, home batteries) and household electronics. This page documents how we work — and just as importantly, what we deliberately don't do.
We focus on durable, consideration-heavy purchases: portable power stations, home backup batteries, MPPT charge controllers, inverters, smart energy meters, robot vacuums, air fryers, espresso machines and mid-range smartphones. Every category gets a hub page with the buying-decision overview plus several deep-dive spokes on specific decisions.
Our recommendations rest on manufacturer datasheets, official specifications, certifications (BSI, CE-UKCA), and UK-specific regulatory context (Ofgem for tariff rules, MCS for installer requirements, BS 7671 for electrical work, G98/G99 for grid connection). We pull live marketplace data from amazon.co.uk via the Product Advertising API for availability and prices. We cross-check our conclusions against independent UK test publications including Which?, TechRadar, Stuff, T3 and Energy Stats UK.
We don't run a lab. We don't stage hands-on tests we haven't actually performed. We don't assign our own star ratings. Where we cite real-world experience reports, we attribute them. Where we give measured numbers or latency figures, they come from the named third-party source or manufacturer spec — not from in-house testing, unless explicitly stated.
Candidates must clear three bars: proven UK market presence (high-street availability or established online stocking), credible third-party validation (professional reviews plus high-volume real buyer reviews), and a fair price-to-performance ratio for the tier. We prefer manufacturers with transparent UK warranties, documented support reachability, and verifiable specs. Marketing claims without evidence get the conservative read. Where US-named brands trade under different names in the UK (e.g. Breville sold as Sage), we use the UK brand name.
Daily Tech Navigator is funded through the Amazon Associates programme. When you click one of our links and buy something on Amazon, we receive a small commission at no additional cost to you. Commission tiers do not influence our picks: we link the product we judge best for the tier, regardless of payout.
Every article shows a visible "Last updated" date and emits a dateModified field in the Article JSON-LD. Hub pages are reviewed at least quarterly for product changes, price drift and ASIN availability. If you spot a stale price, a dead listing or an outdated claim, please tell us through the contact address on our imprint page. Corrections are flagged transparently.
