Do not use these clowns. We called them out at 7pm explained we had problem with heating, they had been out previous evening & said there was air stuck in pump & all was good… we made them aware we have a sick child that had just been discharged from children’s hospital & the cold would affect his disease. We where told someone would be out & they would call us when they where on their way, after 4 hours we called again however no one was picking up, we searched the internet & found another contact, whom told us they would contact them & explain our urgency that we had no heating or hot water. My husband sat up all night waiting yet it is now the following day 11.30am still no one has had the decency to call us & guess what no surprise there no one answering the phones! Read the reviews they speak for themselves…..This is BSW Haywards heath.

My elderly mother has had no heating or hot water for over a week, and BSW Heating have done absolutely nothing to resolve it. An engineer came, said a part was missing, and promised to return — never did. We’ve had no communication since, and I’ve spent hours on hold (over 3.5 hours once while number one in the queue). We were told someone would come between 6 PM and midnight or at least bring a heater — but at midnight, they called to say no one would attend. When I tried to complain, their staff (Sophie) even told me I couldn’t complain directly to BSW until I challenged her. Completely unacceptable service — zero communication, zero care, and no urgency. My mother has been left in unsafe conditions, and it’s shocking that this company handles housing repairs for vulnerable residents.

I am ment to have a boiler service but they just make appointments for you . Have texted them serval time but just ignored. Then they call when you are out. Also gives you a time between 1 and 5 as if people don’t have anything to do with their lives. I have waited in for them and not even turned up

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.
