How Much Does an HVAC Maintenance Plan Actually Cost in London?

If you're looking at an HVAC or heating maintenance plan in London, you probably just want a straight answer.

How much is this going to cost me each year?

For most homes and rental properties in Central London, the honest range is usually somewhere between £350 and £3,100 per year. I know, a huge range.

What Drives the Price?

That's a wide gap, which is why the price can feel confusing at first. The reason it varies so much isn't random — it usually comes down to the type of property, age, how many systems are installed, how integrated systems are, and how detailed the servicing and support is.

Some properties are simple. A single boiler, radiators, no cooling, no pumps, no ventilation system. In those cases, maintenance tends to sit toward the lower end of the range.

Other homes — particularly modern Prime Central London apartments — often include Heat Interface Units (HIUs), underfloor heating zones, mechanical ventilation (MVHR), booster pumps, and sometimes cooling units. The more equipment involved, the more time it takes to inspect, clean, test, and maintain everything properly. That naturally pushes cost upward.

Complexity also matters. Servicing a straightforward boiler is very different from inspecting strainers in an HIU, checking condensate drainage in cooling units, testing pressure stability in pump systems, and reviewing ventilation filters. Some systems simply take longer and require more specialist knowledge.

Property risk plays a part too. In higher-value homes, a small issue can escalate into expensive secondary damage — especially where water is involved. That doesn't mean everything will fail, but it does mean preventative checks often carry more weight.

Real Examples: What You Might Pay

Basic setup: A 1-bed flat in Zone 2 with a single HIU, underfloor heating and ventilation unit — £350–£700/year

Mid-complexity: A 2-bed Knightsbridge apartment with HIU, underfloor heating, comfort cooling and MVHR — £800–£1,200/year

Full system: A 3-5-bed Mayfair property with HIU, underfloor heating, comfort cooling ventilation, smart home and integrated BMS software— £1,200–£3,100/year

When Costs Come Down

Prices sit lower when:

• The system setup is basic

• The equipment is newer

• Coverage is limited to one annual visit without ongoing support

• Systems are standalone and not integrated

Why Provider Prices Vary

You'll also notice big differences between companies.

Some providers charge significantly more. That's often because they include longer servicing visits, more detailed inspection, broader system coverage, highly trained staff or faster attendance if something does go wrong.

Cheaper providers aren't automatically bad — but lower pricing often reflects narrower scope and less training. It might mean a quicker visit, boiler-only servicing, limited preventative checks, or fewer consumables included.

The key isn't whether one is "right" and the other is "wrong." It's whether you understand what's included.

Where MaintainMyHome Fits In

You'll probably want to know where MaintainMyHome sits in all of this.

We're not the cheapest option in London. If price alone is the priority, there are lower-cost providers who offer general servicing.

We offer different membership models to suit different customer profile and priorities and tend not to be positioned as the highest-fee "concierge-style" maintenance company.

We tend to sit in the upper middle of the market.

Our plans are designed for modern London apartments with multiple systems — heating, cooling, ventilation, pumps — where structured preventative servicing genuinely reduces risk over time.

We focus on:

• Proper time spent on site

• Cleaning and inspection of common failure points

• Clear communication

• Practical preventative care rather than reactive fixes

That usually places us somewhere between the lowest-cost boiler-only providers and the premium multi-layer service contracts.

For some properties, that makes sense.

For others, especially very simple homes, a basic annual boiler service may be perfectly adequate.

The Reality of Preventative Care

One thing that's worth saying openly: in quiet years, a maintenance plan can feel unnecessary. If nothing breaks, it can seem like you've paid for very little. That's the uncomfortable side of preventative care — when it works well, it's invisible.

Reactive maintenance works differently. Some years you might spend almost nothing. Other years you might face emergency callouts, urgent winter heating failures, pump replacements, or water damage repairs. Over time, those spikes can add up — but they don't happen predictably.

So the real decision isn't just about the number itself. It's about how comfortable you are with variability.

Making Your Decision

If your property is simple and you're comfortable managing issues as they arise, a basic annual service may be enough.

If your property has multiple systems, cooling, pumps, tenants, or is left empty for periods of time, structured preventative care often makes more sense.

The Bottom Line

In London, £500–3,100 per year is normal for annual heating and cooling maintenance plans, depending on what's installed and how thorough the service is.

The most important thing isn't finding the cheapest option.

It's making sure you understand what you're paying for — and what you're not.
