I had an issue with my boiler, and a radiator. I find Sally from Smith & Byford, very efficient, thorough, polite and informative about what ever the problem was within the boiler system etc. She explains things very well, in an understandable manner. Big thank you to her. Thank you also to S&B for arranging time slot reflecting my request.

I would give a minus if I could! The people I've spoken to on the phone have been lovely, BUT the engineers are useless, say they've turned up and given the office evidence, yet I never see them, then I rearrange and someone calls the office on my behalf, (I live on my own) and rearranges the appointment I never even got a confirmation from anyone of the so called appointment. So 2 wasted days waiting in for no good reason.

Hes great. An absolute asset to S&B. The office staff are always happy and eager to help. Thank you so much to all the staff at S&B. Merry Christmas 🤶 🎄

The gas engineer was fantastic and done an amazing job. Very professional and very helpful and polite. He took his time to listen what the problem was and fix the job . He also left no mess and cleaned up after he had finished. I recommend him to all

Very happy with this service. Friendly and efficient. Really impressed I got a call to say the operative was sick and could I change the appointment, this doesn't happen often with many other contractors. Gave me a chance to change my day.

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.
