Ranked 2 of 10 in Builders in Telford

Best for: retrofit insulation, heat pumps and renovations

Trading as Rubik Builders Limited · Telford · Service area: Telford, Wolverhampton, Walsall

Rubik Builders in short

Rubik Builders is a Hortonwood building firm pairing extensions and renovations with retrofit insulation, heat pumps and solar work. Our judgement: with Federation and TrustMark listings on the register and the round's fullest stated insurance cover, it is one of the best-documented firms here. It suits you if energy-efficiency work sits alongside general building. The record shows extensions and renovations paired with retrofit insulation, heat pumps and solar from the Hortonwood base, with garage conversions and garden rooms also on its trade listings. Cover runs across Telford, Wolverhampton and Walsall, and the site publishes company and VAT numbers beside its accreditations.

Customer reviews are its softest spot: 4.3 from 18 Google reviews, the lowest headline rating in the top three. NICEIC, Gas Safe and MCS credentials are stated on the firm's own pages rather than the registers. Seven years on the company record and a published VAT number add to the paperwork.

Customer evidence is the thinner half of the file: the headline is 4.3 from 18 Google reviews, the softest score in the top three, with no second review platform held. In our view the stated insurance and register listings are the stronger half here, which is the reverse of most rivals.

What counts against Rubik Builders is pricing: no prices or call-out fees are published anywhere on the site. Itemised written figures and the scheme details are what is missing.

Questions about Rubik Builders

Is Rubik Builders any good?

On the evidence, yes for combined building and energy work: it ranks second in our Telford table, holds Federation and TrustMark listings on the registers, and states the round's fullest insurance cover. Its reviews are middling at 4.3 from 18 Google ratings, so read the full page and its sources. Ask for an itemised quote.

Is Rubik Builders registered with a trade scheme?

Yes, on two registers: the Federation of Master Builders listing and the TrustMark firm page both confirm the business, with TrustMark licence 2396010 covering electrical, solar, gas and battery trades. NICEIC, Gas Safe and MCS credentials are stated on its own pages. Ask for the scheme details in writing. Keep any scheme paperwork with the written quote and check the dates match.

What does Rubik Builders charge?

It publishes no prices, rates or call-out fees anywhere on the site, so every job is priced on enquiry. Expect a site visit and a written scope before any figure appears. Send the full job list with your address. Ask for itemised written figures. Set the written figure beside one rival quote before deciding.

The firm works from Hortonwood and covers Telford, Wolverhampton and Walsall. Retrofit and renovation jobs across those towns sit inside its patch. Send your postcode with the job list to confirm you are covered. Use the phone, email or contact route. Confirm your street sits inside the patch before arranging a visit.

How is Rubik Builders ranked?

It ranks second of the ten builders in our September round, chosen for retrofit insulation, heat pumps and renovations with documented cover. We looked first at what customers say, then qualifications and the rest. Read the full review, then ask for the itemised quote. Then weigh the strengths above against the limitations beside them.

How does Rubik Builders compare with the other builders in this round?

It is the best-documented firm below the leader and the only one pairing general building with retrofit energy work at this level of stated cover. Randle below it offers a similar building-plus-energy mix with warmer reviews but thinner insurance statements. Where insulation, heat pumps or solar sit inside the job, Rubik Builders reads strongest; for pure roofing or garden work, other cards suit better.
