Nick and team saved our Christmas! We had left a voicemail overnight and Nick responded to us super quickly the next morning. They were professional and efficient in getting us back up and running that day and have just been to complete the long term fix today. An excellent and reliable team of engineers, we have been really delighted with their work. Many thanks Baystar!

I hadn’t used Baystar before but needed a service of my air source heat pump. Both the service and remedial follow-up visit were quickly organised with the engineers arriving on time. Both engineers were courteous and very well informed, taking time to talk me through the system adjustments in suitably non-technical language. One tricky issue relating to a previously damaged solar thermal panel was dealt with quickly through phone support from the office. I’ve already made a note to call Baystar back for the next service since I think they did an excellent job.

Having moved into a new property with a Air Source Heat Pump we had no real idea how to effectively run the system - Baystar were super helpful in sending round an engineer to explain what we needed to do and how to use the system to get the best out of it - we were super impressed with service we received from both the engineer and office staff. Would highly recommend them

I highly recommend Baystar based on our extensive correspondence for ground source heat pumps maintenance and solar PV consulting. Their service and communication have been outstanding.

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.
