What’s Included in a Boiler Service in Blandford
Our annual boiler service follows manufacturer guidelines and covers every key component. Because we work to a consistent checklist, nothing gets missed — and your service record documents every check carried out on the day.
Our engineer checks the boiler casing, controls, pipework connections, and installation position for signs of corrosion, leaks, or damage. Clearances are also confirmed against current requirements before moving on.
Next, the engineer inspects the flue for blockages, damage, and correct termination. A flue gas analysis then confirms the boiler burns gas cleanly and efficiently — a critical safety check that identifies carbon monoxide risk.
Your engineer inspects and cleans the heat exchanger, burner, spark electrode, and condensate trap in situ. Any signs of premature wear go onto your service record for future reference, so you have a clear history of the boiler’s condition.
Finally, the engineer measures gas inlet and burner pressure against manufacturer specifications. All safety controls are also tested — including the overheat thermostat and pressure relief valve. System water pressure and inhibitor levels are assessed before your service record is completed.
Why Have Your Boiler Serviced Annually?
An annual boiler service is one of the most cost-effective steps you can take to protect your heating system. A boiler that goes unserviced runs less efficiently over time. It consumes more gas, pushes up your bills, and becomes far more likely to break down without warning.
Most manufacturers require annual servicing to keep the warranty valid. Skipping a service risks voiding your cover. It also means small faults go undetected until they become expensive repairs. Catching a minor issue during a routine service typically costs a fraction of an emergency call-out.
For landlords in the Blandford area, there is also a legal dimension. Under the Gas Safety (Installation and Use) Regulations 1998, you must hold a valid landlord gas safety certificate (CP12) for every rental property with gas appliances. Our engineers carry out both the annual service and the CP12 at the same visit, saving you time and cost.

New Boiler Installation in Blandford Forum
When a boiler is getting old, keeps breaking down, or a repair would cost more than it is worth, a replacement is often the better option. We fit new boilers in homes across Blandford and North Dorset, from straightforward combi swaps in Blandford St Mary to converting older village properties off tanks and cylinders.
This is the quickest option if you already have a combi. It is usually fitted in a day, reusing the existing pipework and flue position where it meets current regulations.
Many older homes around Blandford still have a hot water cylinder and tanks in the loft. As a result, converting to a combi frees up space and gives you hot water on demand. We remove the old tanks and cylinder and alter the pipework to suit.
For larger homes with two or more bathrooms, a system boiler with an unvented cylinder gives strong showers in more than one room at once. Either way, we will tell you on the survey which setup suits your home.
What Every Installation Includes
- Removal and disposal of the old boiler
- Chemical system flush and inhibitor to protect the new boiler
- Magnetic system filter, which many manufacturers require for the warranty
- New programmer or timer, and a carbon monoxide alarm
- Glow-worm boilers with up to a 10-year manufacturer warranty, plus our 1-year workmanship guarantee
- Registration with the manufacturer and Gas Safe on completion
Spread the Cost
Finance is available on new boilers, subject to status. Dorset Plumbing Ltd is an Introducer Appointed Representative (FCA no. 834818) of Phoenix Financial Consultants Ltd (FRN 539195), a credit broker, not a lender.

Frequently Asked Questions
Dorset Plumbing charges £69.99 + VAT for a full annual boiler service in Blandford. This covers all major makes and models. The price includes every check, a flue gas analysis, and your service record on the day — no additional call-out fees.
Generally, a standard annual service takes between 45 and 60 minutes. However, if a landlord gas safety inspection runs at the same visit, allow up to 90 minutes. This depends on the number of gas appliances at the property.
Our engineer will tell you about any faults straight away. You then receive a written quote before any additional work starts — no hidden charges. Because our vans stock common spare parts, many faults get fixed on the first visit. No work starts without your approval.
When a boiler has stopped working, our engineers carry out a fault diagnosis and repair instead. In that case, call us on 01258 920333. We will advise the right course of action for your situation.
It depends on the boiler, where it goes and how much pipework needs changing. A like-for-like combi swap costs far less than a full conversion from tanks and a cylinder. We survey for free and then give you one fixed written price, valid for 14 days.
A straight combi swap is usually done in a day. However, moving the boiler or converting from a tank-fed system takes longer, and we will tell you how long on the survey so you can plan around it.
If the boiler is over 12 to 15 years old, keeps breaking down, or needs an expensive part, replacing it is often better value. In any case, our engineer will give you an honest view on both options, with prices, so you can decide.
