Felix was so brilliant and my family and I were hugely appreciative of his help! With a small baby in the house, we needed an immediate fix for our issue for peace of mind, and Felix absolutely delivered, kindly flexing his schedule to get us a solution as soon as possible. He was also extremely mindful of the baby's nap-time, working quietly so as not to disrupt baby's sleep, which was so thoughtful! We will definitely use Polkadot again and we are so grateful to Felix for his professionalism, tidiness, and friendly attitude.

I would highly recommend Polkadot. They were excellent from start to finish. Our boiler broke down in January, which was far from ideal, but they arranged an appointment very quickly to install a new boiler and carry out a full system power flush. Every member of staff we dealt with was friendly, professional, and helpful throughout the process. Pricing seemed reasonable, and we paid what was initially quoted. An outstanding service all round.

Excellent service from start to finish! From speaking to Becky, who promptly arranged for Jon and Nick to visit, inspect, quote, and replace my toilet, everything was handled brilliantly. They were polite, tidy, and incredibly friendly throughout. It’s very rare to find Plumbers who work so well with older properties. Becky even stopped by to make sure everything was running smoothly, asked if she could take a few photos of the ongoing work for their social media and even gave our dog a little walk, such a lovely personal touch! We’ve used Polkadot for many years, and they always show true value to their company. professional, efficient and never wasting time. They’re consistently reliable and I am excited to recommend them. What a 10/10 team!

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.
