We are living in a new development where the plumbing was carried out by this company. Unfortunately, we’ve heard many complaints from neighbours about leaks and other issues linked to their work, and we’ve now experienced problems ourselves. We’ve been in our property for less than two years and already had a major leak from the en suite bathroom. When the company inspected, they claimed the water was coming through cracks in the tiles — which didn’t seem possible given the volume of water that leaked downstairs. After their inspection, I investigated further myself and discovered the issue was with the trap. Instead of acknowledging this, they accused us of causing the damage, without providing any proof, and refused to take responsibility. They are now asking for payment to fix the trap. Based on our experience, and the number of complaints we’ve heard from neighbours, we cannot recommend this company. In our opinion, the quality of their work is poor. We are currently pursuing the matter with the developer through legal action.

I wanted a quote for a new installation for an 8000 sq foot property but the lady who took the call was so rude, explaining they dont do domestic installations she didnt even let me finish the conversation and virtually put the phone down so the company lost my business because I also wanted a quote for a development of 8 unit block of flats for my property company but was not allowed to finish the conversation Amazing how companies can behave on the phone I will just go somewhere else ! If companies behave like that on an initial enquiry I hate to think how they may behave after they have taken on work so beware !

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.
