Spring Boiler Deals April 2026: Alpha, Vaillant and Labour-Only Installations in Liverpool
- 3 days ago
- 10 min read

Spring is the most sensible time of year to replace a boiler. Engineers have more availability than during the winter rush; you are not sitting without heating in freezing temperatures while the work is done, and you have months before the cold weather returns to make sure everything is running as it should.
If your gas bills still make you wince every month, your boiler could be a big part of the problem. Many Liverpool homes are still running on older, inefficient boilers that waste energy every time the heating comes on. The result? You pay more than you need to for less warmth and comfort. Modern condensing boilers are designed to do the opposite. They use far less fuel to produce the same amount of heat, recover more energy from exhaust gases, and run more reliably day to day. Over the lifetime of a boiler, that extra efficiency can add up to significant savings on your energy bills – especially if you’re upgrading from an older, G‑rated appliance. At DD Wilson Gas & Heating Engineers, we’re seeing more homeowners across Liverpool choose efficient Alpha and Vaillant boilers as a way to take control of their heating costs. When combined with simple changes like smart controls, correct boiler sizing, and a well‑maintained system, a modern boiler can help reduce wasted energy and keep your home comfortable for less. In this article, we’ll look at how newer boilers save energy, what to consider when upgrading, and how our Spring Boiler Deals for April 2026 can help you spread the cost of installation while you start saving on your bills.

Spring Boiler Installation Deals
This April, DD Wilson is running three time-limited boiler deals across Liverpool, Merseyside, Wirral and Cheshire, our Spring Boiler Installation Deals. All three are available only for April 2026. Once the month is done, the pricing returns to standard. Here is what is on offer.
The Three April 2026 Boiler Deals at a Glance
Before going into the details of each deal, here is the quick summary:
Deal 1: Combi-to-combi swap, £600 labour only. You supply the boiler and all materials. We provide the installation. Terms apply.
Deal 2: Alpha boiler, fully fitted, £1,599. Down from £1,999. Saving of £400. Includes a free service in 12 months, a magnetic filter and a thermostat.
Deal 3: Vaillant Pro 30kW, fully fitted, £2,200. Down from £2,599. Saving of £399. Includes a free service in 12 months, a magnetic filter and a thermostat.
All three deals close on 30 April 2026. To book or get a quote, call us on 0151 739 8945 or request a quick quote online.
Deal 1: Combi-to-Combi Swap - £600 Labour Only
This deal is aimed at homeowners who have already sourced their own boiler or who want to keep the overall cost as low as possible by supplying their own materials. The price of £600 covers labour only. You are responsible for purchasing the boiler itself, the flue, fittings, controls and any other materials required for the job.
Who is this deal for?
It suits homeowners who are confident in sourcing their own materials, who have been quoted for a boiler elsewhere and want a Gas Safe engineer to carry out the installation, or who have a boiler through a supplier deal and simply need fitting. It is also popular with landlords who manage their own procurement for multiple properties. The boiler being installed must be a combi replacing a combi. If your current setup is a system or heat-only boiler, or if you are looking to change your heating configuration, this deal does not apply, and we would put together a separate quote. You can read more about the different routes available on our boiler installations page.
What the £600 covers
The £600 covers all labour for a standard combi-to-combi swap in a domestic property. This includes removal of the old boiler, installation and commissioning of the new one, gas and water connections, and the standard checks required under Gas Safe regulations. Any work beyond a standard swap, such as relocating the boiler, extending pipework, or upgrading the flue arrangement, would be priced separately before the job is booked.
Terms apply. Please call us on 0151 739 8945 before purchasing your materials so we can confirm the job qualifies and agree on the scope of work.
Deal 2: Alpha Boiler, Fully Fitted - £1,599 (Was £1,999)
The Alpha boiler deal is our most popular April package. For £1,599, we supply and install a new Alpha combi boiler, and include three things that are often quoted as extras elsewhere: a magnetic system filter, a new thermostat, and a free boiler service booked for 12 months' time.
The standard price for this package is £1,999. The April savings are £400.
About Alpha boilers
Alpha is a UK-manufactured boiler brand with a strong reliability record and a wide range of domestic models. They are A-rated for efficiency and carry manufacturer warranties of up to 10 years, depending on the model installed. Alpha boilers are a solid choice for most standard UK homes and a common recommendation for straightforward combi replacements where the priority is a dependable, efficient boiler at a fair price.
We have installed a large number of Alpha boilers across Liverpool, Merseyside and Cheshire over the years. If you have questions about whether an Alpha is the right fit for your property, we are happy to talk through it before you commit.
What is included in the £1,599 deal
Supply and installation of a new Alpha combi boiler, a magnetic system filter installed in line with the central heating system, a new programmable thermostat, and a free boiler service scheduled for 12 months after the installation date. The service helps protect your manufacturer's warranty and keeps the boiler running at peak efficiency through its first year.

Deal 3: Vaillant Pro 30kW, Fully Fitted — £2,200 (Was £2,599)
The Vaillant Pro 30kW is our premium April deal. At £2,200 fully fitted, this is a saving of £399 on the standard price of £2,599. The deal includes the same three extras as the Alpha package: a magnetic system filter, a new thermostat, and a free boiler service in 12 months.
About the Vaillant Pro
Vaillant is one of the most respected boiler brands in the UK market. The Pro range sits at the top of the domestic product line and is designed for homes with higher hot water demand or larger heating systems. The 30kW output is well suited to properties with multiple bathrooms, larger floor areas or open-plan layouts where a lower-output boiler can struggle to keep up during peak demand.
DD Wilson is a Vaillant Advance Master Tech-approved installer. This is the highest tier of Vaillant installer certification, and it means we have met Vaillant's own standards for technical competence, training, and quality of installation. Not every heating company carries this accreditation. It matters because a Vaillant installed by an Advanced Master Tech-approved company typically carries a longer manufacturer warranty and gives Vaillant confidence to back the product fully.
For more on the Vaillant installations our team has carried out, see our Vaillant boiler installation review.
What is included in the £2,200 deal
Supply and installation of a new Vaillant Pro 30kW combi boiler by Vaillant Advance Master Tech-approved engineers, a magnetic system filter, a new programmable thermostat, and a free boiler service booked for 12 months after installation.
Why the Magnetic Filter and Thermostat Matter
Both the Alpha and Vaillant deals include a magnetic system filter and a new thermostat. These are often sold as optional add-ons by other companies, but we include them as standard in both April packages because they make a genuine difference to how long a boiler lasts and how efficiently it runs.
Magnetic system filters
Over time, the water circulating through a central heating system picks up iron oxide particles, commonly called sludge. This builds up in the heat exchanger inside your boiler and in the base of your radiators. It forces the boiler to work harder, reduces efficiency, and is one of the most common causes of boiler breakdowns and early failure. A magnetic filter is fitted in line with the heating circuit and captures these particles before they reach the boiler. It is one of the most effective protective measures available and is recommended by all major boiler manufacturers. Many warranties require one to be fitted as a condition of the guarantee. We also recommend combining this with a power flush if the existing system is more than 10 years old, to clear any existing sludge before the new boiler goes in.
New thermostat
Fitting a new thermostat alongside a new boiler means the two are calibrated together from the start. An old thermostat on a new boiler can cause the system to short-cycle, which is where the boiler fires up and switches off too frequently rather than running through a full cycle. Short-cycling wastes energy and increases wear on the boiler components. A new thermostat also gives you the opportunity to upgrade to a programmable or smart control if you prefer.

Why Spring Is the Right Time to Replace a Boiler
Most boiler replacements happen in winter, when a breakdown leaves people with no heating and no choice. That reactive pattern is expensive and stressful. Spring replacements are planned, unhurried and almost always cheaper.
There are three practical reasons to act in April rather than wait.
First, the engineer's availability is better. Between November and February, our diary fills up quickly with emergency callouts and breakdown repairs. In April, we can usually get an installation scheduled within a few days rather than a few weeks. Second, you are not without heating during cold weather. A boiler installation takes the better part of a day for a standard swap. Being without heating in April is a much smaller inconvenience than being without it in January. Third, if your boiler is already showing signs of age, it is unlikely to make it through another winter without a problem. Our blog post on boiler lifespan covers the warning signs in detail. An old or inefficient boiler is also costing you more to run each month than a modern A-rated model, as we cover in our post on why an old boiler is your home's biggest value killer.
If you are not sure whether your boiler needs replacing or just servicing, we are happy to give an honest assessment. Call us on 0151 739 8945, and we can talk it through.
Finance Options
If the upfront cost is a consideration, DD Wilson offers finance options on boiler installations. Rather than paying the full amount on the day, you can spread the cost over a period that suits your budget. To find out more about what is available and how to apply, visit our finance options page.

Frequently Asked Questions
Are the April deals available throughout April?
Yes. All three deals are available from 1 April 2026 and close on 30 April 2026. Installations do not need to be completed by the end of April, but they must be booked and confirmed in April to qualify for the deal pricing.
What does the £600 combi swap deal include?
The £600 covers labour only for a standard combi-to-combi swap in a domestic property. The customer is responsible for supplying the boiler and all associated materials, including the flue, fittings and controls. Any non-standard work beyond a like-for-like swap is quoted separately. Terms apply. Call us before purchasing materials to confirm your job qualifies.
Can I choose a different Alpha model or output?
Yes. The April deal applies across a range of Alpha combi models suited to your property. When you get in touch, we will recommend the right output based on your home size, number of bathrooms and hot water demand. The £1,599 price applies to a standard domestic installation.
Is the Vaillant Pro suitable for a large house with multiple bathrooms?
The Vaillant Pro 30kW is designed for higher demand properties. It is a strong choice for homes with two or more bathrooms or larger floor areas. If your property is unusually large or has more than three bathrooms, we would assess whether a higher output model is more appropriate before confirming the deal price.
What does the free service in 12 months cover?
The free service scheduled at 12 months is a full annual boiler service carried out by a DD Wilson Gas Safe engineer. It covers a visual inspection of the boiler and flue, combustion analysis, heat exchanger cleaning, a check of all controls and safety devices, and a gas pressure test. It forms part of the standard annual maintenance recommended by all boiler manufacturers to keep the warranty valid.
Do you offer finance on the April deals?
Yes. Finance is available on the Alpha and Vaillant fully-fitted packages. Visit our finance options page or ask when you call for more information on repayment terms.
What areas do you cover?
We cover Liverpool, Merseyside, Wirral, Knowsley, Sefton, St Helens, Halton, West Lancashire, Cheshire West and Cheshire East. For a full list of specific towns and postcodes, see the local areas we cover page.
