Rubik Builders in short

Rubik Builders is a Telford home builder and improvement contractor at Hortonwood, covering retrofit insulation, electrics, gas and renewables to PAS 2035 standards, from design and planning approval through to install [1]. Federation of Master Builders and TrustMark registration is on the issuing registers, with NICEIC, Gas Safe Register and MCS membership listed on the firm's own site [1] [2] [3]. Insurance is stated with amounts, which stands out in this ranking [1].

Customer reviews are few but warm, with Google showing 4.3 from 18 reviews [5]. What counts against Rubik Builders in our judgement is focus and money: the site leads with decarbonisation schemes rather than garden rooms, and it publishes no prices, rates or call-out fees [1].

In our judgement Rubik Builders suits a Telford homeowner who wants a whole-house project owned by one contractor, with the scheme memberships and stated cover to match. Readers who want a dedicated room specialist with room photos and list prices should shortlist below it.

Our verdict

Our judgement: Rubik suits you if you want an established Telford builder for a whole-house project with retrofit, electrics and paperwork in order [1] [2]. The registered accreditations and stated insurance with amounts stand out. What counts against it for this ranking is focus: the site leads with decarbonisation schemes, not garden rooms, and it publishes no prices.

Questions about Rubik Builders

Is Rubik Builders any good?

On the evidence, yes for whole-house projects: it tops our Telford garden room ranking, holds registered Federation of Master Builders and TrustMark membership, and states insurance with amounts [1] [2] [3]. The Google record is small at 18 reviews and the site shows little garden-room detail. Send your project list through the contact form and ask for room examples with the quote.

Is Rubik Builders registered with a trade scheme?

Yes. Federation of Master Builders and TrustMark registration is on the issuing registers [2] [3], and NICEIC, Gas Safe Register and MCS membership is listed on the firm's own website [1]. Ask for the scheme numbers with your quote and check each one on its register before work starts.

What does Rubik Builders charge?

It publishes no prices, rates or call-out fees anywhere on the site [1]. That means the quote does the talking: send the full scope and ask for an itemised fixed quote showing labour, materials and VAT apart. Confirm the warranty terms and the payment stages at the same time.

Where does Rubik Builders work?

The contractor works from Horton Court at Hortonwood in Telford, covering retrofit, electrical, gas and building jobs [1] [5]. Telford sits inside its patch. Send your postcode with the job list to confirm you are covered and ask for a visit date.
