Not counted — no bonus earned, and nothing deducted
Our own calculation, not Google’s and not the contractor’s. Ratings from few reviews are held closer to average, because a handful of five-star reviews is not the same evidence as a long record. The items above can only add to a score, never subtract from one: a contractor scoring nothing on all of them still reaches 80 out of 100 on a strong rating alone. “Not counted” means we have no bonus to award, not that anything is wrong.
Their website says it has been working since 1968.

Taken from their own website (www.mastermechanical-ltd.com), read on September 9, 2026. These are the company’s statements about itself, quoted from the page — not claims we have checked. Ask to see a licence before any gas work.
Master Mechanical Plumbing & Heating has not provided a company history yet. Their own website gives 1968 as the founding year.
