I am really pleased with my bathroom renovation. Todd and team did a fantastic job transforming the space from a bathroom with a bath into a modern open shower. The whole process was smooth from start to finish. Everyone involved was professional, friendly, and respectful of my home. The tiling work in particular is great, and the finish throughout is clean and high quality. Todd kept me updated along the way, and any challenges were handled quickly and efficiently. It’s made such a difference to the space and I’d definitely recommend Todd and his team if you’re looking for reliable, skilled tradespeople who take pride in their work. Thanks again!

We have used Todd for all our plumbing and heating needs for several years and the time had come for a new boiler. Todd has done a fantastic job replacing our very old boiler system with a new Worcester /Hive combination with new radiators. The process went smoothly from start to finish. He is always on time, clean and tidy. The difference has been amazing. We would highly recommend him and wouldn’t use anyone else.

Got in touch with Todd right before Christmas as my boiler broke down and was in need of replacement. Despite the awkward timing Todd was super responsive and booked us in promptly. He turned up on time, worked efficiently and got our heating up and running again when we really needed it! Would highly recommend.

Todd has serviced our central heating boiler for several years now. He seems very thorough and leaves everything clean, tidy and working efficiently. This year he was particularly helpful when we had to reorganise the appointment.

Todd fitted a complete heating system for us and we have been very impressed, with both the standard of his work and how easy he was to deal with. Highly recommend.

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.
