Excellent Service by Management, Admin, & Engineer. From initial assessment, order, supply and the installation of new combi boiler within 2 days. A truly professional and efficient response by Denver Services that could not be faulted. Highly recommend

When my elderly mother’s heating stopped over Christmas I was recommended Denver Services by our usual plumber who was away they were quick to arrange an appointment and had an engineer on site that afternoon he quickly identified and fixed the issue and provided advice. The team in the office were polite & friendly and understood the urgency during the cold snap the day after they followed up to check that my mums heating was still ok and she was warm . Thank you Denver Services

We were recommended your company by our plumber as he was so busy with all the problems brought on by the resent water problems in our area, you sent a very kind plumber the next day who found the problem and fix it temporarily so we could have a little heat and hot water. Unfortunately we did have to wait a couple of weeks before getting it fixed because like every plumber you where so busy too. Finally it's been done, all working ,we found both the men friendly and polite and very tidy and the staff we spoke to in the office so nice, so thank you so much.

We have used Denver several times for boiler services and also a dripping pipe! Their engineers arrive on time and are polite, professional and clear up when they've finished! This time we needed to have our old Aqualisa shower replaced and the workmanship was excellent! Tim took the old shower out and you cannot see the 'join' where the new one is! As is often the case when work is done in our 1930s house there were a couple of unforeseen glitches, but this did not phase Tim who sorted these out very satisfactorily, and we now have a far better shower than the old one! Thank you to Denver and to Tim in particular for his workmanship and problem solving skills! - and also to George who cheerily services our boiler! And not forgetting the lovely helpful admin team, and especially Jo who who has such a friendly and reassuring manner! You can tell this company really cares about the standard of their work and their customer service! We would highly recommend Denver and will continue to use them for any future heating or plumming work!

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.
