Cardo builders .Scaffolding went up end of August,job supposed to last 6/8 weeks. Still up .work on roof only 13days since going up. Company blaming everything except themselves.now informed will take at least another 3/4 months. Small sheltered housing estate now like building site no where to park dirt and filth everywhere. More scaffolding erected on another block.no sign of any work on both blocks this is work or no work by cardo builders

Cardo group are awful! That’s why there hiding under a different name on their reviews, there COWBOYS have damaged my car and others in the apartment block and denied it all! Leaving us with ruined cars, ruined walls! Ruined mental health! Their foreman had me crying in the middle of the carpark as he was so nasty to me! I am a young female and the way cardo treat people is absolutely disgusting, I do not recommend getting work done by them at all!

I live in a disabled access property with a housing association, Cardo came out to do a small groundwork job, they left the first time leaving a massive trip/ fall hazard outside my door,I had to send pics to a serveyors to get them back out, they fitted an ako drain, the work was diabolical, outside my door again, I tripped/ fell and hurt my back, they then came out for a third time to put this issue right, I wouldn’t trust this company with a dust pan and brush,I’ve had no call back off Cardo or my housing association? Disgusting, we pay charges for these reprobates! Do me on social media for pictures.

Absolutely terrible service from Cardo Group, who are carrying out repairs on behalf of Wokingham Borough Council. It’s been over a week since I reported the issue and it still hasn’t been resolved. The customer service is extremely disappointing – I’ve had to chase constantly with no real progress. To make matters worse, they even sent an “out of hours” engineer at midnight who had no idea how to close the water mains. Completely unprofessional and shows a lack of training. I’m left with the same unresolved problem and zero confidence in this company. Would not recommend at all.

Anchor Housing use this company and I have had to wait 7 weeks for them to replace a shower pump - this was classed as an urgent job!! Also had a contractor look at fixing my windows, only to be told 7 weeks later that they need to send someone else, as the contractor that came out had left, and they haven’t ordered the parts that he recommended, so basically need to start from scratch again. Their time scales are shocking not to mention the fact that I have got to have more time off work to accommodate their inadequate staff and total incompetence. I’m really not happy with them, and when I spoke to the supervisor Jasper and expressed my concerns his attitude was one of sarcasm and it is what it is attitude! The only good points - Erin in the office and contractor Carl are both extremely helpful. This review relates to the Crawley office. Would definitely not recommend!!

Frequently asked questions

How do I know you’re properly qualified and certified to install heat pumps?

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).

Can you tell me if a heat pump is actually suitable for my home?

We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.

What type and size of heat pump will you recommend for my property, and why?

We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.

What will the full installation cost be, and what’s included in your quote?

Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.

Can you help me access government grants like the Boiler Upgrade Scheme?

Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.

How much disruption should I expect during installation, and how long does it take?

A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.

Will I need to replace my radiators or upgrade anything else in my home?

After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.

How noisy is the outdoor unit and where will it be installed?

Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.

What warranties, servicing and aftercare do you provide?

You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.

What running costs and savings can I realistically expect compared to my current boiler?

We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
