We recently had our boiler changed into a combi, and received outstanding service from start to finish. The initial consultation was very informative, with multiple options tailored to our specific needs. Rob, the technician who installed the boiler, was excellent. He completed the work smoothly and respectfully, taking great care of our home. Once finished, he made sure we fully understood how to use and maintain the new boiler. During the period between the consultation and installation, Glow kindly lent us electric heaters free of charge so we wouldn’t be left without heating. Fantastic service all around - highly recommended.

Just had the boiler changed to a combi boiler after 26 years of using the old water tank system and these gentlemen did it professionally and without causing any worries for me. They took the water tank out and put a radiator in and showed us how to use the new Hive system, and were near and tidy while being on time over the three days. Thank you so much Glow!

Dan came round and gave a quote for my new boiler install and the price was better than any other company. This was promptly booked in and they could do this before the cold weather really hit. Rob arrived on the date we arranged and installed my boiler. Very pleasant and explained what would be happening each day as this was a relocation along with new system. He worked efficiently, cleared up after himself along with being very pleasant and helpful. The day after they called to check if any concrrns. Would 100 %recommend this company. Great work and a lovely warm home.

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.
