Gas boiler installation completed to a very high standard. The engineer was thorough, knowledgeable, and clearly took pride in his work. Everything was checked carefully and finished neatly. He explained what he was doing, answered questions clearly, and made sure the system was working exactly as it should before leaving. A professional job from start to finish. I would happily recommend him.

Anderson is such a lovely, helpful and efficient tradesperson - he has helped us a few times now by installing a new water tank and emersion heating element for our flat. He is a great communicator and was available to help as soon as he could. I recommend him and will use him again!

Prompt service when I was stuck in a bind. Encountered a broken faucet where I had to close main water valve in order to stop water flow. Called up other plumbers who promised to show up on Saturday and never bothered to even call. Instead I called Pacific Solutiond Sunday morning and Anderson responded promptly. After showing him pictures of the broken faucet, he arrived with a new faucet and went straight to work. Was done in a couple of hours and must say thank you to Anderson once again. Before and after photos enclosed.

I cannot recommend Anderson enough, he came to fix a gas leak and I have never had such a friendly and professional plumber! He identified the problem very quickly, went out and sourced some supplies to fix the leak, coming back and sorting out the issue very quickly and thoroughly. He made sure everything was working as it should before leaving. I was alone at my apartment when Anderson came, and as a female it can be daunting having a stranger in your home. But Anderson was super friendly and made me feel at ease. Such a lovely guy! Thank you so much Anderson!

Couldn’t recommend this plumber more! Anderson was brilliant - he arrived within 3 hours of my call when my boiler suddenly started leaking water. He was super friendly, fixed the boiler really quickly and explained everything to me clearly so I now feel much better able to handle future boiler problems. Really reasonably priced & very efficient!

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.
